新型恒压边力落料拉伸复合模

New Type Compound Die for Blanking and Drawing with Constant Blank Holder Pressure

介绍了用于单动压力机的新型恒压边力落料拉伸复合模的结构及主要设计参数和模具工作过程。该模具压边机构的橡胶厚度小,压边力不受拉伸行程影响,在整个拉伸过程中保持不变,压边效果好,适用性强。

The structure, main design parameters and work process of the compound die installed on single action press and working for blanking and drawing with constant blank holder pressure were presented. Thin robber was used in the blank holder mechanism. The blank holder pressure was not affected by the course of drawing and kept constant for the whole process. The blank holder structure had good effect and applicability.
