ABSTRACT

This design narrates the qualities and application of stamping process, the actualities and the trend of stamping process industry and die industry; the design, first, analyzes stamping feasibility of door joint from aspects of hardware, such as figure, dimension; as well as the analysis of the often-seen technological quality problem of the bent part. Then,it estimates the size of blank parts and calculate the blank layout .It gets the best stamping scheme by analysis and comparison ,and calculates parameters of related procedures, the design chooses matched equipments and draws related process card. Then on the foundation of this scheme, the structure and parts of dies for the door joint are determined. At last, it designs the manufacture method about punch-die of the blanking. The design of door joint involves these working procedures: blanking, bending, punching, and drilling. The blanking, punching compound die and the bending     die and separating die are mainly designed, and the bending die is emphasized, which was designed particularly. These designs are technically feasible, economically reasonable, and safely credible. Therefore the current design can be completely put into practice.

Key words： Door Joint ,stamping, process design, die design
