Abstract：

Car fender can be achieved with four-step stamping after analyzing the product formability and die structure of car fender, and optimizing the steps of the stamping process by rotating wedge. It was introduced that the four-step stamping process and flange-sizing die design of car fender. It was main discussed the working contents of each step, the design points of stamping, the structures of two different rotating wedges and their working principle. Therefore, the working stroke along the length and width direction could be shortened by rotating wedge, and the installation space could be also reduced so as to achieve more working parts installed in the same die. Actual production shows that the stamping process can reduce stamping steps, save tool development and production costs, and improve production efficiency.
