What is the cold pier machine for?

Cold pier machine is a kind of stamping machine in mechanical manufacturing. Under the condition that the raw materials do not change (mainly softening or hardening), the materials are molded into the required shape (generally molded into "steps").

A pair of bevel gears is installed at one end of the crankshaft, a cam device is installed on the driven bevel gear shaft, and a scissors slider is vertically installed on the roller shaft of the driven roller of the cam device. The utility model overcomes the shortcomings of the prior art, and the running friction coefficient and impact force between the parts of the feeding and cutting mechanism are small, so that the equipment runs stably, the running noise is effectively reduced, and the product quality and productivity are greatly improved.

The purpose of cold pier machine:

Steel used to manufacture fasteners and connectors (such as bolts, nuts, screws, rivets, etc.). ) cold heading is called cold heading steel, commonly known as rivet steel. Usually used are quenched and tempered alloy steel, low-temperature tempered alloy structural steel, low-carbon low-alloy high-strength steel, ferrite-martensite dual-phase steel and so on. Cold heading is formed by metal plasticity at room temperature. Using cold heading process to manufacture fasteners not only has high efficiency and good quality, but also saves materials and costs. However, the cold heading process requires high quality of raw materials.

Automatic cold heading of cold-drawn copper wire, aluminum wire and iron wire is a special equipment for producing core-pulling aluminum rivets and semi-hollow iron rivets. The whole structure of the machine is fully automatic from straightening, material selection, cutting, secondary molding to blanking, which has the advantages of stable molding standard and various processing types.
