冲模电火花加工工艺,通常采用机械加工方法,先将凸模及电极制造出来。然后再用凸模式电极穿制凹模,以获得良好的形状,配合及间隙要求,但有一些冲裁模,其凸模(如图1-1钢珠圈落料凸模)由于受到结构形状以及加工手段的限制,采用一般的机械加工方法是很困难的。而采用分解加 Die EDM process, usually using mechanical processing methods, first punch and electrode manufactured. And then use the convex mode electrode to make concave die, in order to get good shape, fit and clearance requirements, but there are some blanking die, the punch (Figure 1-1 bead ring blanking punch) due to the structure and shape The limitations of processing methods, the use of general machining methods is very difficult. And decomposition plus
