Research on high speed cold stamping die
Mould is a tool product which is widely used in manufacturing industry. In modern mass production, there will be no high-quality products without high-level molds. The application of high-speed cold stamping die plays an important role in improving the production efficiency and reducing the product cost.
Taking the computer connector terminal parts as the research object, combined with the practical experience of high-speed cold stamping die development for many years, comprehensively considering various influencing factors, this paper reveals the failure form, failure reason and failure mechanism of the die, and finds out the shortcomings of the die in the aspects of design, manufacture and use. Analyze and solve the stability and high quality requirements of it parts in high speed stamping process. A new structure was introduced into the design and manufacture of cold stamping die to solve the problems of scrap rising and die blocking. The external drawing mechanism was successfully developed to improve the stability of high-speed production. Application of the design and processing technology to reduce stress concentration can improve the accuracy of the die and prolong the life of the die. At the same time, the feasibility and economy of the new structure and new technology are demonstrated. The application of new high-speed cold stamping die structure can increase the stamping speed by more than one time, the product quality is stable, the cost of metal parts is reduced by 60%, and the mass production has good economic benefits. The innovative structure of high-speed cold stamping die is a successful innovative application of high-speed cold stamping technology in the field of it parts blanking. It provides a technical compound idea for the innovation and development of more traditional technologies and processes in other fields.
