Description

Technical Field

[0002] Cold forging is a general term for cold die forging, cold extrusion, cold heading and other plastic processing. Cold forging is a forming process below the recrystallization temperature of the material, and is a forging process performed below the recovery temperature. In production, forging without heating the blank is usually called cold forging. Cold forging materials are mostly aluminum and some alloys, copper and some alloys, low carbon steel, medium carbon steel, and low alloy structural steel with low deformation resistance and good plasticity at room temperature. Cold forgings have good surface quality and high dimensional accuracy, and can replace some cutting processes. Cold forging can strengthen metals and improve the strength of parts.

[0003] In the prior art, when stamping metal products, the position of the punch head will be tilted due to the continuous reciprocating downward punching, and will not always be in a balanced state, resulting in the position of the punch head being tilted when punching downward, affecting the stamping quality of the metal product. Secondly, in the prior art, the punch head is replaced by rotating bolts, and the replacement operation is cumbersome, and the punch head cannot be replaced quickly. At the same time, after the processing is completed, it is easy for the stamped metal product to get stuck with the mold, which is not convenient for the staff to perform batch processing operations. At the same time, due to the change of the material of the metal raw material during processing, it is easy for unexpected situations such as stamping overmold to occur during the stamping process, affecting the processing yield rate.
