Abstract：

The multiposition progressive die design for an automobile dust cover was introduced, and the forming process of this part was simulated and analyzed by the sheet analysis software. The results show that the multiposition progressive stamping process method with blanking, deep drawing, partial forming and flanging can meet the production requirement very well. Based on the layout features of the progressive die, the design of eightposition die structure is finally confirmed, namely, the location hole punching and process notching, contour blanking 1, contour blanking 2, empty position, overall deep drawing and partial rib forming, rounded rectangular hole punching, flanging and piercing, part blanking and carriers cutting. Furthermore, the material strip is arranged with the single oblique row to ensure the material utilization and with the dualside carriers, pilot pins locating, floating device of floating pins and supporting block to assure the feeding precision. After actual production verification, the performance of progressive die is stable, and the good product quality is obtained, which meets the needs of mass production.
