1. Research on Key Technologies for the Design and Manufacturing of Progressive Fine Blanking Dies for Complex Parts
Progressive fine blanking dies for complex parts are a cutting-edge and fundamental technology in fine blanking. Research in this field is expected to significantly promote the overall development of fine blanking technology in China.
Taking progressive fine blanking dies for complex parts such as synchronizer rings, clutch plates, and longitudinal composite progressive fine blanking processes and dies as breakthroughs, this research focuses on key technologies for the design and manufacturing of fine blanking dies, so as to realize the rapid improvement of China’s fine blanking die technology and narrow the gap with other countries as soon as possible.
2. Research on Life Improvement of Fine Blanking Dies and Related Key Technologies
Die life is a comprehensive reflection of the levels of die materials, processes and supporting products.
Carrying out technical research focusing on fine blanking die life can not only solve the urgent problem of excessively short service life of domestic fine blanking dies, but also promote the technological development of die materials, fine blanking processes, supporting tooling and other auxiliary products.
3. Research and Development of Compound Fine Blanking and Precision Forging Technology
Fine blanking and precision forging are two manufacturing technologies developed in parallel.
Workpieces that are too thick for fine blanking require precision forging, while workpieces that are too thin for precision forging must be fine-blanked. The two technologies are closely related and interconnected.
The basic idea of developing the compound fine blanking and precision forging process is to find the combination point of the two processes (such as gear parts with hubs and cam parts with short shafts).
China has a long history and a high level in precision forging. Making full use of this advantage is an effective way to improve the overall level of fine blanking technology in China.
