1. Research on key technologies for design and manufacture of complex fine blanking dies for complex parts
Continuous fine blanking die for complex parts is the advanced basic technology of fine blanking technology, and it is expected to promote the whole fine blanking technology in China. Taking synchronizer gear ring, clutch piece, longitudinal composite continuous fine blanking process and continuous fine blanking die for complex parts as breakthrough points, the key technology of fine blanking die design and manufacturing is studied, which can realize the rapid improvement of fine blanking die technology in China and shorten the gap with advanced countries as soon as possible. Such
2. Improvement of die stamping die life and related key technologies
Die life is a comprehensive reflection of die materials, workmanship and the level of supporting products. Taking the life of precision blanking die as a key technical problem, it can not only solve the problem of low life of precision blanking die urgently needed in China, but also promote the development of die materials, precision blanking process, supporting tooling and other auxiliary products.
3. Research and development of fine blanking and precision forging composite technology
Precision blanking and precision forging are two advanced manufacturing technologies developed in parallel. Precision blanking is too thick and needs precision forging. Precision blanking is necessary for precision forging which is too thin. The basic idea of developing precision forging-precision blanking composite process is to find the combination point of the two processes (such as gear parts with hub and cam parts with short shaft). However, the precision forging in China has a long history and the level is very high, so it is a good way to improve the overall level of precision blanking technology in China.
