The continuous fine blanking die for complex parts is the frontier basic technology of fine blanking technology, and it is expected to promote the whole fine blanking technology in China. Taking the synchronizer gear ring, clutch plate, longitudinal compound continuous fine blanking process and continuous fine blanking die for complex parts as the breakthrough point, the key technology of fine blanking die design and manufacturing is studied, so as to realize the rapid improvement of fine blanking die technology in China and shorten the gap with advanced countries as soon as possible.
- Study on the life promotion of fine blanking die and its related key technologies
Die life is a comprehensive reflection of die material, process and supporting product level. Taking die life of fine blanking as the leader to carry out technical research can not only solve the problem of low die life which is urgently needed in China, but also drive the technological development of die material, fine blanking process, supporting tooling and other auxiliary products.
- Research and development of fine blanking precision forging composite technology
Precision blanking and precision forging are two advanced manufacturing technologies developed in parallel. If the precision blanking parts are too thick and need precision forging, if the precision forging parts are too thin, they must be precision blanking. They are interrelated and closely related. 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 wheel hub and cam parts with short shaft). The precision forging in China has a long history and high level This is a good way to improve the overall technology level of our country.
