What does stamping mainly rely on? Stamping relies on presses and molds to apply external force to sheet metal, strip material, pipes, and profiles, causing plastic deformation or separation to obtain workpieces (stamped parts) with the required shape and size. What problems do you think might exist during the stamping process? Let's have Yixing Xindake analyze them for you!

Stamping and forging both belong to plastic processing (also called pressure processing), collectively referred to as metal forming. The blank materials for stamping are mainly hot-rolled and cold-rolled steel sheets and strips. Among all the steel produced worldwide, 60-70% is in sheet form, most of which is made into finished products through stamping. Car bodies, chassis, fuel tanks, radiator fins, boiler drums, container shells, motor and electrical core silicon steel sheets, etc., are all processed by stamping. Instruments and meters, household appliances, bicycles, office machinery, and household utensils also contain a large number of stamped parts.

1. Mold issues

The dies used in stamping processes generally have specialization; sometimes a complex part requires several sets of dies to be formed, and the dies are manufactured with high precision and technical requirements, making them a technology-intensive product. Therefore, only when the production batch of stamped parts is relatively large can the advantages of stamping processing be fully realized, thus achieving better economic benefits.

2. Safety issues

Stamping processing also has some problems and disadvantages. The main issues are the noise and vibration generated during stamping, which are considered public nuisances, and safety accidents involving operators occur from time to time. However, these problems are not entirely caused by the stamping process or the molds themselves, but are mainly due to traditional stamping equipment and outdated manual operations. With the advancement of science and technology, especially the development of computer technology, and the progress of mechatronics, these problems will certainly be resolved quickly and comprehensively.

3. High-strength steel stamping.

Today, high-strength steel and ultra-high-strength steel have effectively achieved vehicle lightweighting, improving vehicle crash resistance and safety performance, and thus have become an important development direction for automotive steels. However, as the strength of sheet metal increases, traditional cold stamping processes are prone to cracking during forming and cannot meet the processing requirements for high-strength steel sheets. When forming conditions cannot be met, international research has gradually focused on hot stamping technology for ultra-high-strength steel sheets. This technology is a new process that integrates forming, heat transfer, and phase transformation, mainly utilizing the properties of increased plasticity and reduced yield strength of the sheet metal in the high-temperature austenitic state, and shaping it through molds. However, hot forming requires in-depth research on process conditions, metal phase transformation, and CAE analysis technology. Currently, this technology is monopolized by foreign manufacturers, and its development domestically is slow.
