During the development of metal stamping parts processing technology, the process parameters and the shape and size of the working part of the stamping dies should be correctly determined to improve the quality of stamping parts and shorten the trial production period of new products. Based on strengthening the theoretical research of stamping forming, the stamping forming theory should be able to play a guiding role in production practice and gradually establish a set of advanced process analysis and calculation methods closely combined with production practice.
Foreign countries have begun to use elastic-plastic finite element method to carry out stress-strain analysis and computer simulation on the forming process of automobile cover parts, to predict the possibility and possible problems of forming parts by a certain technological scheme. To speed up product renewal and overcome the defect of long mold designs to cycle, the research on CAD/CAM technology of molds should be vigorously carried out.
In our country, special attention should be paid to the research of multi-station progressive CAD/CAM technology. To meet the needs of mass production and reduce labor intensity, it is necessary to strengthen the research on the mechanization and automation of stamping production, to enable the general medium and small pieces to be produced by multi-position progressive dies on high-speed presses, to achieve a high degree of automation in production, to further improve the stamping productivity, to expand the application range of stamping production, and to make cold stamping suitable for both mass production and small batch production. It can produce both general precision products and precision parts. Attention should be paid to the development of new forming processes such as precision blanking (especially fine blanking of thick materials), high-energy forming, soft die forming, pressing and superplastic processing, and the application of simple dies (soft dies and low melting point alloy dies), universal combination dies, numerical control punches and other equipment should be promoted.
