What is blanking die

Continuous fine blanking die for complex parts is the advanced basic technology of fine blanking technology, which 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 die 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.

2. Research on key technology of improving die life

Die life is the comprehensive reflection of die material, small craft and supporting product level. Taking the fine blanking die life as the leader to carry out technical research can not only solve the problem that the service life of fine blanking die is too low, but also promote the technological development of die material, fine blanking process, supporting tooling and other auxiliary products.

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

Fine blanking and precision forging are two advanced manufacturing technologies developed in parallel. If the precision stamping part is too thick and needs precision forging, and if the precision forging piece is too thin, it must be fine blanking. The basic idea of developing the composite process of precision forging and fine blanking is to find the combination point of the two processes (such as gear parts with hub and cam parts with short shaft). Precision forging in China has a long history
