Abstract
Under the conditions of economic globalization, China’s manufacturing industry has developed rapidly. The cold stamping die processing method has been widely used for its advantages of high efficiency, low cost, and high volume and rapid production. The design of molds has also become increasingly important, especially in the In the automotive industry, nearly 90% of auto parts use mold processing. This paper analyzes the part features of the FSC-PLANE component 6801BF8-141, analyzes the blanking process and the drawing process properties of the material, formulates a reasonable forming process for the part, and performs a feasibility analysis. The shape, size, etc. of the blank processed by the part were analyzed, and the calculation of the dimensions and tolerances of the process force, the pressure center, and the working part of the mold were performed. The deep drawing, blanking-punching, and turning of the car seat side plate were finished. Side mold. It also specifically analyzed the design and manufacture of the main parts of the mold (such as flanging molds, unloading devices, backing plates, blanking dies, drawing dies, punches, etc.), as well as the clearance adjustment between male and female molds. A detailed list of the required parts of the mold is listed, and reasonable assembly drawings and part drawings are given, as well as the processing technology of the main parts of the mold.
Key Words:car seat side panel forming;deep drawing;blanking – punching;flange
