Abstract：

It was introduced that the application of a car bumper mounting bracket progressive steel plate mould. Then, by analyzing the stamping process and die structure of the bumper mounting bracket, a set of progressive die for stamping process and the die were designed to complete the production. By the automatic feeding of the coil and the gradual continuous stamping of several stations, the automatic production of parts was realized. Furthermore, the sheet in the die was positioned precisely by a number of positioning devices to greatly improve the production efficiency and reduce the tooling cost of the punch and labor costs. Finally, by on-line production verification, the stamping process and progressive die of the bumper mounting bracket ensured the precision requirements and quality requirements with high efficiency and low production cost.
