Research on key technology of design and manufacture of continuous fine blanking die for complex parts
Continuous fine stamping die for complex parts is the frontier basic technology of precision punching technology. 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 the level of mold materials, small arts and supporting products. Taking the life of precision punching die as the leading point to solve the problem of too low life of precision die, it can not only solve the problem of too low life of the die in China, but also promote the development of die materials, fine blanking technology and 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, the precision forging must be too thin. They are closely related. The basic idea of developing precision forging precision stamping composite process is to find the combination points of these two processes (such as gear parts with hub and cam parts with short shaft). However, precision forging in China has a long history and has a high level. It is a good way to improve the overall level of precision punching technology in China.
