Abstract:

 Considering the occupant safety and automobile lightweight, the application of high strength steel plate in automobile manufacturing industry is more and more widely. The material of the connecting plate of a car side threshold is high strength steel DP590, which has high yield strength and tensile strength. In view of geometric characteristics and the presence of the forming difficulties, the forming process of the part was analyzed, and the plan of adopting four sets of compound die to complete the stamping process of forming parts was determined. The structural design for drawing die and compound die with cutting,punching,trimming and repairing was conducted, and the structure of cutting parts of the compound die was analyzed in detail. Production practice proves that the designed four sets of compound die plan can improve the processing efficiency and product quality, and also meet mass production of the needs of the connecting plate of a car side threshold.
