How to make a cold forging machine with your own hands For many craftsmen who decide to try hand-made forging tangible products, the snail used for cold forging has become an important tool in their work. This machine is rarely found in sales, so it is recommended that you assemble it yourself. Structurally, it is a device used to manufacture solid products or individual elements in the form of spirals: such objects are usually forged grilles, fences, steel decorative ornaments and other parts of the system. The snail used for artistic forging is suitable for bending samples with a diameter or side (in the case of a square cross-section) up to 11-13 mm; if necessary, the equipment can be equipped with automation and electric devices to facilitate the work of experts and speed up production process. Created features Most varieties are created by independent drive and manual drive, suitable for processing thin workpieces. The volute machine used for cold forging can handle larger parts with a thickness of more than 13 mm, but its size is too large and not always convenient. If the workshop area is limited, the equipment can be improved in another way (installation of electric drives). The power of the machine is increased, so it can handle thicker workpieces without increasing the size of the tool itself. The cold forging process is carried out at a low speed, because when exceeded, the geometry of the workpiece will be deformed sharply, resulting in the formation of cracks on the surface. If the machine is used to make thin and curly curly hair and gorgeous decorations, there is no need to use an electric drive for design. It is important to not only assemble the motor correctly with your own hands, but also to determine the gear ratio of the gears of the gearbox to ensure uniform and smooth processing without the risk of obvious defects, so as to correctly determine the motor’s power. When creating a snail diagram, it is important to determine the automation design and the location of activation elements, control buttons, and other components so that the equipment works as efficiently as possible. You can make all the machines for manual cold forging with your own hands. Through your proficiency in technology, this is how to make a very useful machine. Its working principle is as follows: See also: Homemade dark blue electric guitar delay pedal. Such equipment makes work easier and greatly improves productivity. The aforementioned device for cold metal forging is not difficult to manufacture, easy to operate, and not whimsical. If there is no reason to purchase high-performance equipment to meet the needs of factories, etc., but you plan to install it in a small furnace, you must have all the necessary conditions to order the necessary equipment with your own hands or from a homemade craftsman. This investment will pay off soon. You can start small and gradually expand your machine park. Decorative ornaments and furniture made of wrought metal have always been popular. They are not only known for their beautiful appearance, but also for their extraordinary strength and long service life. These items can usually serve generations of owners inherited by fathers and sons. In addition, the process of forging metal to make artwork is always done by hand, so each product is proprietary and different from similar analogs. With cold forging, you can make exclusive forged products at home. At the same time, such products can not only be produced using heating traditionally associated with forging concepts, but also by cold forging. If the first one requires both forging and special qualifications, the second one can easily be produced independently at home. In this way, you can make glass grilles, fences for the front garden and backyard, railings for stairs and balconies, canopies on doors, and interior decorations such as chairs, beds, sofas and fireplace grilles, flower stands and fireplace accessories. Each such homemade food will be exclusive. Main structural elements In most cases, the manufacture of forged volutes includes the following: Main parts. Active shaft. A lever of mechanical force. Workpiece fixing elements. The lever used to monitor and control the pressure roller, the pressure roller itself. Fix the fingers of the plowshare. Slot for moving the pressure axis. A spring used to pull the shaft. Axis linkage axis. In order to better understand the design, you can view the drawings. These drawings have machine projections on different sections and should indicate the size ratio between the parts. Creation method This process is carried out in stages, and its function algorithm is as follows: Before making a snail for cold forging, preparations are required, in which paper drawings and templates for future design are prepared. At the same stage, it is necessary to determine the size of the material to be processed with self-made tools: the larger the diameter of the rod used as the blank, the wider the stride of the machine. The size of the latter always exceeds the diameter of the blank. Working surface: The cold forging machine has a platform, which is made of sheet metal with a minimum thickness of 4-5 mm. The surface area itself depends on the size of the part to be processed, because the volute must be kept in such a position during the cold forging process so that it is convenient and safe to use the volute. To create the shape, a 3 mm thick metal plate can be used to make it easier to use the finished equipment. It is recommended to fix the edge of the workpiece, as this has a pressure shaft in the equipment. In addition, a cutting rod with a length equal to the strip of the workpiece can be used as a fixing element. It is important that the material is firmly fixed in place, because it is physically impossible to fix it manually while the cold forging machine is running. If you use detailed drawings and instructions, you can assemble the main parts of the machine in a few hours. The homemade snail used for cold forging work can have a monolithic or foldable system: the choice depends on the master's preferences and the time he is willing to spend on creation. If the workshop is equipped for a period of time, the prefabricated model is especially important. If the room is permanent, it makes sense to design a monolithic device. The snail itself can be made of the following materials: thick metal strips. Bend it to the desired position and rotate it the required number of turns, and then fix it on the workbench by welding. A piece of metal from which it is cut and bolted to the surface. If you need to use a variety of blanks and create parts with different shapes and crimp numbers, you can assemble a workbench on which there will be multiple devices that can release the required types of items. The forging press uses this equipment to produce various spiral and ring shapes, wavy shapes, and crimps. In order to manufacture such a manual cold forging machine, it is necessary to operate according to a certain technique, which includes several stages. Before manufacturing any equipment, art forging machine or hand tool, it is necessary to make sketches, templates, graphic images of future products. If you cannot make a complete drawing, please create a template, which will help you with subsequent operations. In order to make the marking more accurate, it is more convenient to use graph paper. Draw a spiral on it, where the turning radius should gradually increase. The same distance must be maintained between them. It should be noted that since the concept of artistic value is individual to everyone, this condition must be met only when the pattern is required to be symmetrical. This also applies to the number of turns-usually no more than 4. See also: Self-made mechanical wood splitter with your own hands. Please consider the workpiece you will use in advance. The steps between turns must be made slightly larger than the diameter of the iron rod, otherwise it is difficult to remove the finished part from the machine without damaging its shape. You will need sheet metal for the work surface. A thickness of 4 mm is sufficient. The determination of the linear size is based on the size of the future product. To make a mold, use 3 thick strips. You can use hand tools to handle such materials. Use normal pliers to simply bend it into a spiral shape. In order to ensure a complete workflow, you will need a good fixation at one end of the workpiece. A rod equal to the width of the strip is convenient. The workbench can be used to strengthen the work area. Sometimes a part of a thick-walled pipe is used as a support, and it is necessary to ensure that the structure reinforced in this way does not interfere with other types of work. For this, you can choose the option to fix the entire assembly in a vise. The most important thing is to ensure the greatest degree of fixing reliability, because huge physical effort will be expended during the cold forging process. How much is this process? Do-it-yourself construction of snails is relatively cheap, and the cost includes the following: the materials used to prepare the spiral, the table top, and the fasteners used to assemble the structure. The complexity of the structure created by the machine can be used. The cost of materials used to form metal products. Finishing agent (primer, paint, varnish, etc.), the choice depends on the product type, use and design features. It takes some time to self-assemble the snail machine for cold forging, but it can save you a lot of the cost of buying a ready-made version, the price of which is at least 20,000 rubles. If the equipment fails, it will be more difficult to repair. Before starting work, it is necessary to prepare the drawings of the snail model machine, and then carry out the work of manufacturing the machine according to the drawings: they can be made into ready-made drawings or engineering drawings that consider future tools independently, and take into account personal wishes and extensive Application scope. Usually, the template is made on graph paper, and the new spiral will be larger with each revolution. If the step parameter is indicated in the figure, the design must be carried out in consideration of the ratio. The cold forging machine is an important tool for metal craftsmen. It can be used to manufacture various decorative objects and interior decorations. It is forged from metal and is a multi-stage but uncomplicated process. If you have instructions, drawings, and time, you can use rolled metals (channel steel, plates, rods, etc.) and tools such as grinders, drill presses, and lathes to complete the work alone. Any craftsman equipped with a smithy needs minimal tools and accessories. However, usually, the simplest technical operation of metal blanks can only be completed in the first stage. With the accumulation of work experience, the desire and demand for art forging emerged-this is not only home decoration, but also additional income. Unfortunately, the snail-like machine used to mold samples is not actually on sale. Usually, in one way or another, but home craftsmen make with their own hands. The subject of this article is the self-design and assembly function of the snail for cold forging. The characteristics of snails The author specifically decided to attract readers' attention to the following points. This will help avoid some errors in the future. For example, after clarifying the structure of the snail and its functional principle, someone will want to assemble their own device, which is different from the device that will be introduced below. Such a device is quite good (if we are talking about manual devices), it can bend samples with a cross section (square sides) no more than 11-13. This refers to the snail model. In fact, no one has anything to do with the large samples in daily life. The machine can also be improved by installing drivers and motors. But how reasonable is this for a small blacksmith shop? Cold forging is performed at a low speed. Rapid changes in metal geometry can cause cracks (fractures). You not only need to choose the motor/motor power, but also the gear ratio of the gearbox. In addition to this-install the automation circuit by installing the appropriate components (buttons, starters, etc.). All this significantly complicates the manufacture of the machine. Conclusion-For the home blacksmith shop, the snail is enough, you can use it to bend metal products by hand. Anyone who understands the nuances of its design and at least understands electrical engineering knowledge can independently install electrical/drivers on it. The adaptable manual rigging cannot be attributed to the machine tool, even if the technical operation performance of them is considered with the help of powerful force. On the Internet, the tools, equipment and accessories used for forging are usually mixed together. We have explained the differences here, but here, we only discuss the equipment, which is more complicated than manual tools, but more complicated than electric power. The machine is simple. However, by analogy, the fixtures have the same name. Each type of machine has its own unique fixing device. See also: Technical Specifications of Metal Snail Twisting Machine Snails belong to the category of machines in which shapes are formed by twisting the workpiece. The main equipment in the design is the equipment made in the form of movable and foldable parts of patterns or fixed templates. The bottom surface of the tool performs the function of obtaining elements according to the drawing size. Torsion bar This is a device used to twist or twist a metal bar around its axis. The task solved by the tool is to securely fix the rod end, ensure free rotation, and eliminate the possibility of deflection of the rotating shaft. To make a flashlight, a tubular mandrel was used. The workpiece is obtained in three dimensions. Bending machine-bending machine Generally, the bending machine is called the bending machine. The equipment used to bend steel bars at a specific angle has the same name. A simple tool, consisting of rollers and stops, can bend rods and steel belts according to a given pattern. Self-made whip wave device The main part of the device is a movable and fixed roller with a stop device, allowing you to obtain a wave-shaped profile on the rod. The length and amplitude of the wave can be different. Manual equipment or pipe benders for bending special-shaped pipes can be made manually. The simplest original equipment is a bent pipe, which does not require high bending accuracy. If other equipment (such as a jack) is placed in a self-made structure, the strength loss of the finished bending element is small. In cold forging, some elements are called crow's feet. It is easily obtained by rolling the standard equipment used for this purpose. At the same time, equipment for performing this technical operation has been developed. They are made in the form of self-made embossing rollers or embossing equipment. In order to manufacture such self-made products, performers are required to have high qualifications and special materials. Conductor The conductor is used in the snail machine to obtain a crimped, spiral-shaped device. They are mandrels whose contour corresponds to the manufactured component. There are two main design types for the machine: the fixture is made in the form of a foldable rotating template with a gate on its axis. With fixed fixture and rolling roller. Make curls for the railing on the self-made fixture. If you add another door to the snail machine by rotating sharing, you can get a smooth wavy product. By changing the distance between the doors, you can get various contour waves. Several devices are shown in the snail making diagram. Things like this (on the basis) should work. Assembling the snail by yourself is one of the options for self-design. When you can't give a suggestion that shows the exact parameters of all components, you can design it yourself. Here, you need to focus on your own thoughts on the way and way of bending (radius, number of turns of the spiral, etc.). However, if the nature of the manufacturing process becomes clear, then the assembly itself will not cause difficulties. The cold forging process of table design requires a lot of work. If you already have a finished workbench, you may need to enhance it. When making snails from scratch, the table frame is made of metal only-channel, angle steel, thick wall tube. Obviously, the desktop should also be metal. The snail will be subjected to static and dynamic loads during operation. Therefore, ordinary iron sheets are not suitable. Only one board, and at least 4 mm. The layout and installation of equipment is perhaps the most creative stage of work. You can do everything yourself. But how do you think about the prospects or limit yourself to producing the same type of samples? Option 1. The simplest. The focus of the operation is to draw the outline of the spiral on the desktop. In fact, this is a sketch of the future curled part, for example, starting with a bar graph. After that, you can cut out a few pieces from the thick strip of iron and bend it along the radius. Weld them to the workbench, and the bending mechanism is basically ready. See also: Drilling machine for metal models. Someone will find this design more attractive-with a strong steel belt. But practice shows that it is more difficult to use this snail. For example, when removing the finished product from it, certain difficulties will arise. Option 2. Same, but multiple contours are drawn. Drill a hole along each hole and cut threads in it. It just prepares a template for the stop segment. They are usually made of thick cardboard or plywood with their own hands. On it, the lining plate is made of metal, and after the next mark, a hole is drilled in it that matches the platform in the plate. This design will allow the production of spiral blanks with different radii to be organized on one table. Depending on the shape of the elbow, only appropriate sections need to be installed in certain positions. They are fixed on the base. You can take different actions. Instead of stopping like this, put cylindrical ones.

If you have your own hands, you can sculpt it yourself in a few hours. Option 3. Prepare several removable modules that can be changed as needed. The assembled snail has been installed with a plow, a lever, and a side baffle. All of this can be clearly seen in the figure. Everything in the barn (garages, things in the attic) will be used-trim pipes, rails, corners, etc. If you understand how snails work, you no longer need any skills. The feature check is always implicit, so it is not commented. In principle, manufacturing snails for cold forging is not that difficult. In addition, there is no uniform standard for this equipment. Some people will say-isn't it easy to buy a factory model? First, as mentioned earlier, you will need to search for a long time. Secondly, it is a fact that its ability does not match the master's fantasy. Third, you have to reduce the wallet at least about 19,000 rubles (manual) and 62,000 rubles (electric). Make snails with your own hands, good luck!
In order to add beauty and sophistication to the metal gates or fences of country houses or private houses, spiral elements are increasingly used. In order not to buy such elements in stores, manufacturers of fences and gates usually bend them themselves. To make spiral steel parts yourself, you need a special device called the cochlea. With the help of such a device, the metal rod, the strips of different parts are bent. If the right-angle section of the workpiece is 13 at most, bend this type of workpiece with both hands at room temperature (so-called cold forging). Figure 1. Diagram of a snail. Considering that people who usually use metal processing need this kind of machine, they can make it by themselves. In order not to waste time and money, redesign the wheels and the snail drawings made for cold forging will help them. For the manufacture of spirals, it is best to use low-carbon metals due to its good ductility. General equipment of the machine Figure 2. Diagram of the snail. The snail for cold forging is a pipe fixing device that contains a device for fixing the workpiece. A shaft with a spiral element is connected to a thick metal disc or plate. The end of the rod or strip is inserted into the fixing device, and then it is wound on the spiral element with a rotating shaft. The bending is caused by the action of the pressure roller, which presses the workpiece against the screw element. According to the design and size of the required product, for each type of stamping part, single or multiple snails with the ability to change its curvature can be produced. There are several drawing options for manufacturing cold forging machines. According to the type of axis drive in the machine tool, they are manual and electric. First, consider the drawing of a manual cold forging machine.
First, use various types of additional equipment to cut the metal into the required workpieces. In addition, the above-mentioned machines and equipment will be used to process all these parts. This is the main task of cold forging. The manual press used for cold forging can be used in the first stage of metal processing. What I want to point out is that the cold forging process does not include heating the metal. It is this fact that accelerates the entire manufacturing process. In addition, the quality of metal elements is also improved. If we conditionally divide cold forging into several stages, we can distinguish two main stages: this is processing on a press, and then bending. Importantly, this does not require increasing the temperature of the metal being processed. It is this fact that affects the improvement of the strength characteristics of the parts and the reduction of flexibility. What is the most popular cold forging product? It can be attributed to it with certainty: metal grilles to protect windows; decorative details of fences; furniture interior decoration products (including flower stands, candle holders, etc.); exterior wall elements such as canopies, fences, and railings. All these products can be manufactured using cold forging equipment. Diagram of the machine with manual drive Figure 3. Diagram of the snail seat. It is mounted on a base, which is a rectangular plate with dimensions of 221 191 cm. The 5 mm thick plate has two holes. One of them is round with a diameter of 15 mm and is used for the shaft; the other is elliptical, 6 mm closer to the axis and 7 mm from the axis (Figure 2). The base is welded to two legs, which have a hole for fixing them (Figure 3). The shaft axis has a tapered end. It is firmly fixed to the base by two 15 nuts. The drive shaft rests freely on the shaft, which has a head with two mutually perpendicular threaded channels (Figure 4). The handle is twisted into these channels. Parallel rails (2 pcs) are welded to the bottom surface of the base along the rectangular holes. Figure 4. Diagram of the snail shaft. The screw element (the snail itself) is prefabricated. It consists of 4 elements, hingedly connected by pins passing through the lugs (Figure 5). Each connecting pin of the volute section has a slotted head. The arc-shaped lug has holes for connecting pins. They are welded to the end of the segment. The degree of curvature of the cochlea is adjusted by a special adjustment screw that is screwed into the connecting end of each of the three parts so that they are close to the end of the previous part. There is a slot for a flat-head screwdriver on one end of each adjusting screw. See also: What is lead-tin solder? The central part of the cochlea is an eccentric wheel with a hole for the drive shaft, the first part of the screw element and a fixed incision. The fixed incision is an eccentric semicircular depression in the first part of the section, with a radius of 7 and its center 8 from the center of the section. Like the other parts, the thickness of the central part is 26 mm. Figure 5. Diagram of the snail segment. An eccentric wheel with a corrugated lower part is arranged in the guide device, and a thumb screw is inserted in the transverse channel of the head of the eccentric wheel. The latter is aligned with the semicircular cut of the drive shaft and then welded. The slider is inserted into the longitudinal hole of the base, and the slider is pressed against the base from below. The sliding block with flange cut can be freely installed between the guide rails. The roller shaft is screwed into the upper part of the slider with hexagon head. The roller itself can be freely placed on the roller shaft. Therefore, the roller can occupy a position along the elongated hole of the base and be fixed in any such position by screwing the roller shaft to the slider. Using this device is very simple. First, insert the end of the rod or strip into the groove of the drive shaft. By using the wing to rotate the eccentric, the workpiece is clamped between its lower end and the groove wall. To this end, the roller is brought to the workpiece, and the roller shaft is screwed on the slider with a No. 15 wrench to clamp it. The workpiece is placed between the eccentric wheel and the roller in the central section of the volute. Next, rotate the drive shaft clockwise to wind the workpiece on the middle section. When the work piece is wound to the end of the center section, the second section is connected to the section using a connecting pin. At the same time, the roller moves to a new position. By analogy, it will bend until the workpiece is formed into the desired shape. In order to remove the final product from the machine, the eccentric is rotated with the wings and releases the end of the workpiece. After lifting the drive shaft with the eccentric wheel and the entire volute, move the volute out of the generated spiral. For a long time, people have learned to use metal to make beautiful products. These can be ornate lanterns, canopies, fireplace elements, wrought iron furniture, awnings and fences. Until recently, such products were created in the arduous and complicated work process of blacksmiths. So far, modern equipment has appeared on the market, with the help of which forged structures can be manufactured without heating the metal. The advantage of manual cold forging is that now, when it is used with metal, there is no need to master any complicated technology and make actual efforts. It is enough to know how the equipment works and how to use it correctly. Hand forging tools. Price In order to manufacture complex forged structures, professional equipment with electric motors or hydraulic systems is required. The cheapest and most affordable cold forging hand tools can be purchased in specialized stores.
This will make it possible to manufacture basic forged products in various configurations. It includes a support for processing long workpieces, an eccentric wheel for holding squares and bars, and a mandrel for crimping. The equipment price starts from -19,700 rubles. Longitudinal distortion hand tools-designed for use in domestic environments.

The product is twisted with a section of 501 mm, but the length can be increased independently. The price of this equipment is 35578 rubles. Do-it-yourself machines Some household craftsmen make their own manual equipment for cold forging. Using the drawings provided on, you can easily assemble the machine. Tools and metal parts required: First, a spiral diagram with three circles must be drawn on a piece of paper. After that, you need to check the dimensions in order to put the 11-diameter reinforcement rod into the thread. Now you can start manufacturing the machine. The private sector in any city has all kinds of exquisite metal products. These are metal patterned doors, beautiful benches, unusual railings and other decorative ornaments. Forged products make the appearance of the site and the house more beautiful. Many people think that metal forging fixtures are very expensive. But this is not always the case. This product is made by cold forging. If you buy them in a store, then of course you can pay a considerable amount. Therefore, experienced craftsmen make cold forging machines with their own hands. In addition, if a person likes to do something by himself, then the device will come in handy on the farm. Moreover, for artistic forging, you can get a considerable income. After all, production costs and initial deployment costs are small. Therefore, the affairs of blacksmiths engaged in cold forging can quickly go up the mountain. Forging, maybe in a garage or shed. Therefore, rent for premises is not required. Torsion bars As mentioned earlier, these cold forging machines allow you to bend longitudinally on the tie bars. This is a relatively simple structure. The main task is to fix one end of the rod immobile and connect the rod to the other end so that the workpiece can be twisted. As a basis, it is suitable to use cuts of thick-walled (at least 3) shaped tubes. The cage can be welded with the same rod, leaving a square gap of the required diameter. You can use the appropriate size clamp (available at the rigging store). Any one of these stops is welded to the base. The cable holder is an excellent holder for rods. Next, you need to somehow ensure that the second part of the artifact is captured and distorted. This can be done using two bearing assemblies. A tube of appropriate diameter is inserted inside, and a handle is welded on one side-the structure is similar to a letter. On the other hand, a fixer was made in the pipeline: four holes were drilled and nuts for 15 or 15 bolts were welded into it. The result is a good retainer-tighten the bolt after inserting the rod. The bearing unit is used for the fixture of the workpiece. This is the appearance of the overall structure. In addition-a technical problem-using a lever, we can rotate the required number of turns. This is not to say that this job is prepared for the weak, but because of the great leverage, it is not that difficult. The next video is a simpler machine that uses cold forging to make torsion bars. Cold forging concept The difference between the cold forging process and the hot forging process lies in the simplicity and safety of the process. The metal is not exposed to high temperatures. Compared to stamping, this process means that metal flow is almost completely eliminated. If we consider cold forging, from the point of view of the forging process itself, then this is the process of riveting parts using impact force. As a result, the strength of the outer layer is increased, and the interior is imparted with overall toughness and fracture toughness. Of course, the forging process itself is very long. Therefore, it is necessary to discuss some branches of cold forging called artistic forging in more detail. Essentially, it is also cold forging, and this concept will be used later. It includes various bends of the metal source. The structure of the metal substrate is unchanged. The physical and mechanical properties are also not affected. Cold forging involves the formation of various twists and turns. Such patterned elements are made in a specific device. In addition, the drivers of these devices are divided into manual and electric. For a large amount of work, it is best to use an electric machine to increase the execution speed. Manual installation can be used to produce the following decorative items: Window structure. Components used to make armrests. Chairs, benches. Furniture feet. Doors and ticket gates for decorative items. Details of the fireplace. As for the raw materials used for forging, different types are used: aluminum and copper. You can also use alloys-duralumin, steel, brass, magnesium alloy, nickel alloy. Types of cold forging machines Modern cold forging machines can be driven by electric motors or mechanical forces. A machine with an electric motor can make you do many tasks much faster than manually, but this requires the special skills and work experience of the master. Several modern types of machine tools are used in cold forging technology: 1. A snail machine with detachable or solid parts for manufacturing spiral parts; 2. A general machine for cutting, riveting and forming products; 3. A bending The machine is designed for arc bending of metal parts at a certain angle; 4. The twisting machine allows you to bend along the axis of the finished product. 5. Machine wave, allowing wave-shaped elements to be obtained from metal rods; 6. Pressing, allowing matrix printing on the finished product; 7. Machine, forming rings from metal rods. Advantages of this method Compared with other methods of producing metal products, cold forging has many advantages. Among them: there is no need to heat the metal, and because there is no furnace, the manufacturing process can be simplified and a certain temperature can be maintained. Process safety. Easy to manufacture cold forging equipment. The ability to correct products made due to mechanical properties. Have the ability to use standard procedures to manufacture the same product equipment. Save working time and money. The existence of these advantages makes cold forging technology widely used. There are many types of equipment for cold forging equipment. The following categories have been established:-Facilitate the production of metal arcs that bend at precise angles. Snail-This device allows you to form a spiral from the rod. -Allows you to obtain more complex spirals along the axis. The ring is a bending mechanism for making rings and ellipses. Wave-The device is designed to bend the rod into a wave shape. Press-allows you to flatten the object. Hammers and anvils are tools for correcting mistakes. It is very easy to make each type of cold forging machine by yourself. Only some tools and metal materials are needed. Moreover, almost no money is needed. Machinery In order for each product to be of high quality, the machinery and fixtures used for cold forging in the workshop must be of different types. It is necessary to form a corner. It is assembled by a special steel plate, and the lever and two supporting shafts are fixed on the steel plate. It is very simple to manufacture this equipment for metal cold forging with your own hands. If you have decided to engage in the production of molded products, you should definitely pay attention to the existence of a machine named. It is very simple to make. Strict compliance with the drawings of the cold forging fixture is sufficient. The use of tool steel is also very important. It is almost impossible to make a cold forging machine for cold forging mechanism with your own hands. It is necessary to establish a separate mechanism for releasing objects. When manufacturing the unit, please select the following materials: metal plate (preferred thickness is 4-5mm); steel bars, special-shaped tubes; representing the stability of cold forging fixtures; if it is a driven machine, the motor and gearbox. Of course, manufacturing fixtures cannot be separated from tools. It is recommended to use an angle grinder or metal file, welding machine, sandstone or paper, vise and pliers as well as a pencil, tape measure and paper. For new craftsmen, it is easiest to make a homemade snail-shaped cold forging machine. Thanks to her, small gates and fence metal rods of various shapes were produced. Moreover, twist installation is very popular. After obtaining simple installation experience, other forms of machine tools can be manufactured. Let us analyze manufacturing in detail. This device helps to obtain various configurations of spirals, crimps, and loops. The simple design of the equipment facilitates easy operation and easy access to the workpiece. The process can be carried out under the following conditions: metal rod. Steel leaves and stripes. Profile tube. Welding machine. Angle grinder and pliers. To manufacture self-made machines used in the cold forging process, it is recommended to draw drawings or sketches of future fixtures. Initially, choose graph paper to draw the graph. The following phases of work: Apply a three-circle spiral image to the paper. The size should correspond to the diameter of the reinforcement, provided that the reinforcement fits the thread. It is best to use a size of 11. And the line should be drawn according to the thickness of the steel, and the distance inside the spiral should be 15-15. Next, you need to use a steel grinding wheel to make a circle of the required diameter. If you want to use a movable wheel, you should use a non-thin raw material (4-5 mm thick) for easy replacement. Forging a solid foundation for stability on the floor surface. Usually, you can concrete the legs to get a stronger structure. An important condition is that the perimeter of the bed must be greater than the size of the working circle. Weld the metal rod to the base where the bearing device is installed. Manual control involves welding the wheels to the bed. In this case, metal bending is much easier than the spinning process. We fixed the snail on the circle. The snail is divided into three parts. The height of the tail is 1 cm based on the thickness of the rod. Add 1 cm to the next part of the spiral, which means the second turn will be 2 cm and the third turn will be 3 cm. As you get more turns, you should increase the details of the spiral. If you need to make a replaceable circle, weld the replaceable parts to the circle according to the sketch. If you have a replaceable snail, you need to measure the position of each type and solder the stud to each element. In this case, a certain gap will be left on the circle. To obtain counterfeit products, you need to start with the central loop. The rod must be firmly fixed with a vise or other tool. Finally, you need to make a lever with two special-shaped tubes (diameter 16-21). They are welded with a bridge, and the length is the distance from the center of the bearing to the apex of the arc plus 5, and then welded to the bearing component. A rod having a length corresponding to the length of the highest part of the snail is welded to the lower part of the lever, which is used as a cut circular part. The folding bucket is welded perpendicular to the circular area. In this way, the homemade machine is ready. You can start generating the required elements.
