The cold-heading machine is a stamping machine in mechanical manufacturing.
When the raw material is not changed (mainly softened or hardened, etc.), the material is shaped into a desired shape (generally formed into a “step”).
A pair of bevel gears are mounted on one end of the crankshaft, and a cam gear is mounted on the driven bevel gear shaft, and a scissors slider is vertically mounted on the roller shaft of the driven roller of the cam device.
The utility model overcomes the deficiencies of the prior art, and the running friction coefficient and the impact force between the components of the feeding and cutting mechanism are small.
Smooth operation of the equipment, effectively reduce operating noise, and greatly improve product quality and productivity.
The steel used for the manufacture of fasteners and joints (such as bolts, nuts, screws, rivets, etc.) by cold heading is called cold heading steel, commonly known as rivet steel.
Quenched and tempered alloy steels, low-temperature tempered alloy structural steels, low-carbon low-alloy high-strength steels, and ferritic-martensitic duplex steels are commonly used.
Cold heading is plastically formed using metal at normal temperature.
The use of 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.
It adopts cold drawn copper, aluminum wire, iron wire and other automatic cold heading. It is a special equipment for producing core aluminum rivets and semi-hollow iron rivets.
The whole structure of the machine is automatically carried out from straightening, material selection, secondary forming to blanking, and has the advantages of stable forming standard and many varieties of processing.
