The problems existing in the precision stamping is introduced

 1 the mold, stamping die problems processing use generally has specificity, sometimes is a complex parts need several sets of mould to processing and forming, and mold manufacturing of high precision, high technical requirements, are technology-intensive products. Therefore, only under the condition of the stamping production batch is bigger, can fully embody the advantages of stamping processing, can achieve the good economic benefit. 2, security stamping processing also exist some problems and shortcomings. Mainly displays in the stamping process of two pollution, noise and vibration and the operator safety accidents occur frequently. However, these problems is not entirely due to the stamping process and die of itself, and is mainly due to the traditional stamping equipment and backward manual operation. With the progress of science and technology, especially the development of computer technology, along with the progress of the electromechanical integration technology, these problems must be resolved as soon as possible and perfect. 3, high strength steel, ultra-high strength steel of high strength steel stamping today good realize the lightweight vehicles, improve the performance of vehicle collision strength and security, thus become an important development direction of automotive steel. But with the improvement of sheet metal strength, the traditional cold stamping process prone to cracking phenomena in the molding process, cannot satisfy the requirement of the high strength steel plate processing technology. In the processing conditions, can't meet current international research of ultra high strength steel plate hot stamping technology gradually. The technology is a combination of forming, heat transfer and phase change of a kind of new technology, main is to use high temperature austenitic state, the sheet of plastic, the characteristics of yield strength decrease, through the mould forming process. A: what is the automotive stamping parts?
