Homemade cold forging machine: manufacturing process

The creation of forged products is done with the help of hot and cold processing. The latter method does not require special skills, but special devices are needed for its implementation. There are various drawings of cold forging machines, Many of which are suitable for self-creation tools.

Production features

Formed forged metal elements as a result of deformation, while in the course of work the performance characteristics of the material must be taken into account.

The structure of the crystal lattice of the metal consists of grains having irregular shapes. The tool used for forging affects it and leads to a change in the shape of the part. Of particular importance is the selection of drawings of machines, since the workpiece must retain its previous properties.

Homemade cold forging machine: manufacturing rules

There are certain rules, compliance with which ensures the necessary result:

• Creating a suitable configuration is possible using several tools.
• Before the beginning of manufacturing, the parameters of the formed products are calculated.
• The bars used for blanks may have a different diameter, which is selected taking into account the degree of complexity of the technique and subsequent operation.
• Only low-carbon steel is treated, since other types do not have the necessary plasticity.

"Gnutik"

Hand machines for cold forging can be made independently, it is enough to understand the intricacies of using the tool and to choose the appropriate drawing. "Gnutik" is necessary for creating corners of various configurations. Its main structural elements are the driving stop and two shafts located on the steel plate.

Homemade cold forging machines of this kind must be created in accordance with some features. For example, the angle of deformation must be determined initially. It is also possible to add an additional bending element, if used, a third rotational shaft is mounted.

The tool is made of special steel, since it is subject to heavy loads in the process. It is worth noting the possibility of collecting various details, including undulating ones.

"Twister" and "Snail"

Today art forging can not do without details in the form of auger. They are created by hand for cold forging Under the name "Twister". They have a characteristic feature, which consists in scrolling the rod along the axis. The tool consists of a movable and a fixing part. The swivel handle deforms the workpiece, which is fixed between the main parts of the structure. It is worth noting that the spiral is formed on the side of attaching the product, and the applied forces can be reduced by a competent calculation of the lever that exerts pressure. This device allows you to manufacture parts for metal fences and window grilles.

"Snail" is a simple homemade cold forging machine that provides the formation of spirals with the required number of turns. It is the most popular and can be adapted for the manufacture of the desired product. The tool is equipped with a manual or electric drive, the type of which is selected in accordance with the intensity of operation.

Homemade cold forging machine: preparation of materials

To begin with, it is necessary to draw a spiral with an identical pitch of all the turns. In this case, it is necessary to repulse the used workpieces, since the width of the stroke, as a rule, is within 15 mm, while the tool is intended for bars with a cross section of 10 mm. Free space is necessary for maneuver, since with full compression of the workpiece, bending becomes impossible.

Next, you need to cut a plate 20x20 cm in size from a steel sheet. Despite the small size, it will ensure the optimal performance of the workflow. In accordance with the length of the alleged "snail", a cut of steel is made. The band must be bent with pliers, placed on a plate and outlined with a bright marker on all sides.

Next, a part of the rod with a length equal to the width of the steel strip is cut off. The main thing is that it does not exceed this parameter, as this can lead to injuries in the process of bending. A rod is needed to secure the material in the first stage of the product creation, in order to prevent a free stroke at one point.

A section with a length of 10 cm is cut off from the profiled pipe . It will join the sheet and the base on which the fixation will be made. Due to the high degree of load, only thick-walled materials should be used. After all the basic elements have been prepared, you can collect a homemade cold forging machine, the drawing of which is presented below.

Assembling the structure

The steel "snail" is divided into coils, the first of which will hold the workpiece, while the others will be run by the turns of the rod. The central part is welded to the base, and even the smallest defects should be absent on the welded joint. The pieces of the rod are welded to the main part of the strip, the distance between them should be 3 cm. Care must be taken when forming the seams, and then knock them down with a hammer.

Then the stripes are set in the necessary places and are drawn with a marker. The resulting circles are needed to form holes. They must fully comply with the diameter of the legs for easy installation and removal.

The final stage is the welding of the profile pipe in the lower part, as well as the fixing element next to the "snail". Photos of homemade cold forging machines made in this manner are presented above.
