图1所示零件(材料08F),经落料、冲孔复合模具、外缘翻边、打凸复合模具及切口、弯曲复合模具三道工序完成。图1B-B部视部分成型用的切口、弯曲工序的复合模,在不设计顶件装置的情况下,经冲压后,零件会牢牢地嵌在凹模的型腔内,由手工直接入模取出零件,很不安全。为确保安全生产,提高工作效率,从模具改革着手,采取了以 The part (material 08F) shown in FIG. 1 is completed in three steps by blanking, punching composite mold, flange turning, convex composite mold and incision and bending composite mold. Figure 1B-B partial view of the molding part of the incision, the bending process of the composite mold, without the design of the top device in the case of stamping, the parts will be firmly embedded in the cavity of the die, by hand directly into Mold out parts, it is not safe. In order to ensure safe production, improve work efficiency, starting from the mold reform, taken to
