Briefly introduce the punching process in stamping parts

Hardware stamping parts manufacturers have multiple processes when stamping parts are processed and formed, which are divided into two categories: separation and deformation processes. Among them, blanking and punching are separate processes, and stretching and bending are deformation processes. Each process has its special processing characteristics, this article briefly introduces the punching process for you. The traditional method of punching punching parts is to use punching dies to process 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 characteristics, but due to pipe punching 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.
