1. Key technologies for design and manufacture of complex precision die for complex parts

The continuous fine blanking die for complex parts is the frontier basic technology of fine blanking technology. This is the starting point for research, and it is expected to drive the upgrading of the whole fine blanking technology in China. With the continuous precision punching die of the complex parts such as the synchronizer ring, the clutch plate and the longitudinal compound continuous fine blanking process and the mold, the key technology for the design and manufacture of the fine blanking die is studied, and the rapid improvement of the fine blanking die technology in China is realized, and the gap with the advanced countries is shortened as soon as possible.

2. Improvement of die stamping die life and related key technologies

Die life is a comprehensive reflection of the mold material, small art and the level of the supporting products. With the life of the die as the leading technology, it can not only solve the problems that are too low in the life of the fine blanking die at present, but also promote the development of die material, fine blanking process, and the technical development of the supporting tooling and other auxiliary products.

3. Research and development of fine blanking and precision forging composite technology

Fine blanking and precision forging are two advanced manufacturing technologies in parallel. Fine blanking parts are too thick and need precision forging. Fine forgings must be fine punching. They are interrelated and closely related. The basic idea of developing the compound process of precision forging and fine blanking is to find the combination of these two processes (such as gear parts with wheel hub and cam parts with short axis), and the precision forging of our country has a long history and the level is very high, and it is a good way to improve the overall leveling of the fine blanking technology in our country.
