带凸缘阶梯筒形件的成形工艺研究

The Study of the Forming Process of Stepped Cylindrical Work-piece with Flange

通过对一个带凸缘的阶梯形筒形件的拉深工艺计算，说明带凸缘的阶梯筒形件的拉深工艺的计算方法。用该方法计算确定的拉深工艺，可以确保多次拉深过程中的拉深过渡形状不被拉断，最终拉出合格的工件。

This paper illustrates the calculation method of forming stepped cylindrical work-piece with flange though an example of similar drawing work-piece. The method with which the drawing process have determined , makes it possible for the work-piece to avoid breaking in drawing ,and obtain a required work-piece finally.
