Mold is an important foundation for process equipment manufacturing industry in the national economy plays an important role in various sectors . Progressive Die is a high efficiency, high precision and high- life and other advantages of the mold, is widely used in various industries stamping production . With the development of technology for progressive die forming quality requirements are high, but the traditional progressive die design less fully to consider the factors that affect the forming precision , resulting in the design and manufacture of error , and finally to precision parts decreased . Load disc progressive die stamping design involves theory , stamping process plan , layout design, product expanded size calculation , mold design, product simulation, and the forming mold material selection and many other key technologies. This paper discusses the progressive die stamping theory and numerical simulation based on the relevant issues , combined with a typical example of the load plate , use a step inverse forming finite element method to get rough dimensions, and after repeated numerical simulation analysis, proposed a including three positive deep drawing, deep drawing twice against 28 working steps of progressive die stamping process forming solutions . On this basis, both by simulation analysis , comparison and design of a new type of progressive die carrier - kerf vector, which in the course of progressive die forming small deformation, can significantly improve the feeding accuracy, improve Progressive Die stamping accuracy, especially suitable for deep drawing progressive die forming . Orthogonal experiment FEM simulation and optimization of the load plate progressive die stamping process parameters , get the best coefficient of friction ( lubrication conditions ) , BHF , punching speed , die clearance and other process parameters. Finally focused on the main die structure design , and quick-change mold structure discussed. Conclusions and results obtained herein , the actual production of certain guiding significance and reference value.
