Precautions when using metal stamping machine
1. Mold problems of metal stamping machine
The molds used by metal stamping machine are usually special. Sometimes a complex part requires several sets of dies to be processed and formed. With high precision and high technical requirements, the dies are technically intensive products.Therefore, the advantages of metal stamping machine can be fully reflected only when the stamping parts are produced in large batches, thus obtaining better economic benefits.
2. Metal stamping machine safety
Metal stamping machine also has some problems and shortcomings.It is mainly manifested in two kinds of hazards: noise and vibration produced during stamping, and safety accidents of operators occur from time to time.However, these problems are not entirely caused by stamping process and die itself, but mainly by traditional stamping equipment and backward manual operation.With the development of science and technology, especially computer technology, and Mechatronics technology, the safety problems on metal stamping machine will be solved as soon as possible and perfectly.
3. Metal stamping machine for high strength steel
Nowadays, high-strength steel and ultra-high-strength steel realize vehicle lightweight very well, improve vehicle crash strength and safety performance, so they become an important development direction of vehicle steel.However, with the increase of sheet strength, the traditional metal stamping machine, which uses cold stamping, is prone to fracture during the forming process and can not meet the processing requirements of high-strength steel plate.At present, metal stamping machine which utilizes hot stamping technology of ultra-high strength steel plate is mostly used in the world when forming conditions can not be met.The technology is a new process that combines forming, heat transfer and microstructure transformation. It mainly uses the characteristics of high temperature austenite, increasing plasticity of sheet metal and decreasing yield strength, and forming technology through molds.
