About cold forging machine

Cold forging machine is a stamping machine in machine manufacturing that molds the material into the desired shape without any changes (mainly softening or hardening and other similar treatments).

A pair of bevel gears are installed at one end of the crankshaft, a cam device is installed on the driven bevel gear shaft, and a scissor slider is vertically mounted on the roller shaft of the driven roller of the cam device. The utility model discloses has overcome the deficiencies of the prior art, and the running friction coefficient and impact force between each part of its feeding and cutting mechanism are small, so that the equipment runs smoothly, effectively reduces the operating noise, and greatly improves product quality and productivity.

The steel used to manufacture fasteners and connectors (such as bolts, nuts, screws, rivets, etc.) by the cold heading processing method is called cold heading steel, commonly known as rivet steel. Commonly used are quenched and tempered alloy steel, low-temperature tempered alloy structural steel, low-carbon low-alloy high-strength steel, ferritic-martensitic duplex steel, etc. Cold heading is plastically formed by metal at room temperature. The cold heading process is used to manufacture fasteners, which not only has high efficiency and good quality, but also saves materials and low cost. However, the cold heading process has high requirements for the quality of raw materials.

It adopts automatic cold heading of cold-drawn copper, aluminum wire, iron wire, etc., and is a special equipment for the production of top-drawn aluminum rivets and semi-hollow iron rivets. The whole structure of the machine is automatically carried out from straightening, material selection, cutting and secondary forming to blanking, which has the advantages of stable forming standards and many processing varieties.
