摘要：

通过对汽车翼子板产品成形性及模具结构可实现性的分析，合理排布各序冲压工艺内容，并采用旋转斜楔机构有效实现了翼子板四序化生产。介绍了一种可实现四序化生产的汽车翼子板冲压工艺方案及其翻边整形模设计，重点讲述了该工艺方案中各工序的工作内容、设计要点以及两种不同形式的旋转斜楔机构的结构及工作原理。旋转斜楔机构的应用可缩短模具长宽方向上的工作行程，减小了安装空间，有利于更多的工作机构在同一副模具内安装。实际生产证明，该冲压工艺方案可有效降低冲压工序数，减少模具工装开发成本及后期生产成本，提高生产效率。

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.
