Abstract：

The application of a switching mechanism with flowering wedge in automobile roof flanging die was introduced. Through the analysis of the stamping process and die structure on the top of the wedge mechanism, the flanging processes with and without roof skylight were realized in one die by the pneumatic switching mechanism and the flowering wedge mechanism respectively. Furthermore, their structure and working principle were expounded, and the designed structure can reduce die tooling development cost, save occupied area of stamping workshop and improve the efficiency. After verification, the total precision of the production with and without skylight reaches 94% which meets the accuracy requirements of outer car plate.
