Abstract：

According to the shape, size and production requirements of automobile reinforcement plate, the stamping process was analyzed, and the layout and die design of progressive die were conducted. Then, the process was analysed combined with Dynaform software to determine that the central part of product could be formed at one time stamping. In view of the problems of many bending parts of product and large amount of springback after forming, the bending accuracy was effectively ensured by using the pre-pressing process, and aiming at the multi-sided bending characteristics of product, the stability of strip feeding and stamping was improved by using the frame-type layout structure. Furthermore, the combination of floating guide pin and corrected pin further improved the punching accuracy. The production results show that the forming scheme of bending in several times can improve the accuracy of product, the structure of die is reasonable, which can ensure the production efficiency and yield rate of product, and realize the large-scale production, which has important reference significance for the actual production.
