1. Research on Key Technologies of Design and Manufacture of Continuous Fine Die for Complex Parts
Continuous fine blanking die for complex parts is the frontier and basic technology of fine blanking technology. 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 a breakthrough point, the key technology of design and manufacture of fine blanking die is studied, so as to realize rapid upgrading of fine blanking die technology in China and shorten the gap with advanced countries as soon as possible.
2. Research on Life Improvement of Fine-blanking Die and Related Key Technologies
Die life is a comprehensive reflection of the level of die materials, small arts and supporting products. Taking the life of fine blanking dies as the leading technology to tackle key problems can not only solve the problem of low life of precision blanking dies urgently needed in China at present, but also promote the technological development of die materials, fine blanking technology, supporting tooling and other auxiliary products.
3. Research and Development of Compound Technology of Fine Blasting and Fine Forging
Precision blanking and precision forging are two advanced manufacturing technologies developed concurrently. Precision blanking is too thick and needs precision forging. Precision blanking is necessary for precision forging to be too thin. They are closely related. The basic idea of developing precision forging-fine blanking composite process is to find the combination point of these two processes (such as gear parts with hub and cam parts with short axle). The precision forging in our country has a long history and has a high level. It is a good way to improve the overall level of fine blanking technology in our country.
