There are many problems in my country's precision stamping parts industry

Precision stamping parts have an important position in industrial production. After recent years of development, my country's precision stamping parts industry has gradually become formal, and it is also making great efforts in the international market, but it is leading to a higher development direction. There are still many difficulties and many problems, mainly manifested in the following aspects.　　1. Poor manufacturing process 　　 The research on the manufacturing process of precision stamping parts has accumulated a large amount of proprietary technology in the world, especially the century-old factory, the technology accumulation has reached the expert level. However, the domestic accumulation of know-how in precision stamping parts is very small and there is still a long way to go.　　2, short life 　　The prominent problem that affects the life of precision stamping parts is the quality of materials and heat treatment. At present, because the price of imported steel is too expensive, most precision stamping parts still use domestic steel when the output is not very large. However, the quality of domestic steel is not good, coupled with process control such as forging and heat treatment, and unstable quality, resulting in a large difference in overall life, which is generally 1/3 of that of foreign countries. 3. Poor analytical ability. Foreign research on finite element numerical simulation technology and precision stamping parts stress analysis simulation and verification technology for the fine blanking process has reached a high level, and has been applied to the design verification and design of precision stamping parts Verify, optimize structure, etc. Although some domestic universities and research institutes have carried out basic research work in this area, there is still a certain gap in the application research of these technologies.　　4. Low standardization 　　 In order to enhance the overall capability of my country's precision stamping parts industry and promote the development of industry standards, it is particularly important to formulate my country's precision stamping parts national or industry standards in the context of comprehensive international standards and the actual development of my country's industry.
