Stamping parts processing plants, processing metal stamping parts, stainless steel stamping parts, sheet metal stamping parts, etc. There are many processes in the processing and forming of stamping parts. Each process has its unique processing characteristics. Today, I will briefly talk about the punching process; generally The punching plates are: stainless steel plate, copper plate, iron plate, aluminum plate, low carbon steel plate, galvanized plate, PVC plate, cold rolled coil, hot rolled plate, copper plate, etc.; the traditional method of punching punching of stamping parts is to use stamping Mold, processing through holes on the plate. There are many punching methods, such as pipe punching, sheet punching, and hydraulic punching; 1. Pipe punching and sheet punching have many similarities in terms of deformation properties and deformation characteristics. However, due to pipe punching and sheet punching, there are many similarities. It is a hollow cylindrical blank. When punching, the tube wall that the convex and concave molds contact is an isolated surface instead of a flat surface like a plate. Therefore, special process measures and mold structure forms are required. 2. Hydraulic punching, as a new type of punching method, punches hollow parts and parts whose axis is curved, which has the advantages that traditional processing technology can't match. The hydraulic punching process does not require a die during the entire punching process of stamping parts, which has great advantages in solving the processing of parts that cannot be placed inside due to the small internal size or the curved axis. At the same time, the use of hydraulic punching instead of laser cutting plays an important role in reducing the production cost of parts and improving production efficiency; parts formed by the hydroforming process have the advantages of saving materials, reducing costs, and good performance. With the extensive use of hydroformed parts. The processing method of the hole on the part has attracted more and more attention from domestic and foreign scholars. Because the tubular hydroformed parts are hollow, traditional processing methods cannot be used for punching, and laser cutting methods are generally used for processing. Although good processing quality can be guaranteed, the equipment investment is expensive, which is not conducive to reducing costs. Article recommendation: What is the quality standard of the solder joints in the welding of metal stamping parts?
