Abstract：

In order to increase production efficiency, reduce cost process and decrease time of production preparation, on the basis of analyzing the technological characteristic of automobile inner panel, the one-step flanging process was used for the stamping of sheet. Then, the die parts of flanging were designed and assembled by using CATIA as a computer-aided design tool, and the three-dimensional digital model of the die assembly was generated. At the same time, the structural design features of the working parts for automobile inner panel die were introduced, namely, the upper die of flanging adopted insert die structure, the inner was used for pressing material and upper die of forming, the lower die were divided into fixed punch and movable jacking punch. Furthermore, the die was positioned by the process hole in the blank, the upper and lower dies were guided by the guide sleeve and guide post, the guiding between upper die and pressing plate adopted the guide slider and sliding surface, and the guiding between lower die and lower insert punch was conducted by the guide sleeve and guide post. The result shows the designed die has good process property and reasonable structure, and meets the production requirements.
