Punching process in stamping parts processing

Stamping parts processing plant can produce and process metal stamping parts, stainless steel stamping parts, sheet metal stamping parts, etc. There are many processing processes for stamping parts, and each process has its own special processing characteristics. Today, Precision will talk about the punching process in the stamping process based on past experience: Common punching plates are: stainless steel plates, copper plates, iron plates, aluminum plates, low carbon steel plates, galvanized plates, PVC plates, cold rolled coils Etc.; The traditional method of stamping parts is to use punching dies to process through holes on the plate. There are many ways of punching, pipe punching, sheet punching and hydraulic punching. 1. Pipe punching and sheet punching have many similarities in deformation characteristics and deformation characteristics. However, because the tube is a hollow cylindrical blank, the wall of the tube contacting the male and female dies during punching is isolated. It is not as flat as a flat plate, so special processing measures and mold structure are required. 2. As a new type of punching method, hydraulic punching can punch hollow parts and parts with curved axis, which has advantages that traditional processing technology can't match. In the entire stamping process of stamping parts, hydraulic stamping does not require molds. This has great advantages for handling parts that cannot be placed in the mold due to too small internal dimensions or bent shafts. At the same time, replacing laser cutting with hydraulic punching plays an important role in reducing the production cost of parts and improving production efficiency. The parts formed by the hydroforming process have the advantages of saving materials, reducing costs and having good performance. With the extensive use of hydroformed parts. The processing method of part punching has attracted more and more attention from scholars at home and abroad. Because the tubular hydroformed parts are hollow, traditional processing methods cannot be used for stamping, and laser cutting is usually used for processing. Although good processing quality can be ensured, the equipment investment is expensive and is not conducive to reducing costs.
