1.引言插片是我厂数种继电器应用量最大的零件之一,图1零件材料为黄铜H62,厚1.2mm,原采用冲压工序为①落料,⑦打扁。由于是单件两工序加工,零件尺寸一致性不好,致使在压扁工序时,零件定位困难,生产效率低,满足不了生产需求,因此我们设计一套六工位级进模二工序在一套模具上完成。2.排样设计通过分析,该零件的台肩,槽口和台肩距边尺寸的略微变化井不影响零件的使用,根据其结构特点,把图1修改为图2,并把原排样形式图3设计成图4所示,其工序为:一工位冲圆孔及切除一边废料;二工位切另一边废料;三工位冲圆孔;四、五工位压扁;六工位落料。3.模具结构及零件加工特点图5为模具结构图。模具采用四导柱、滚珠导套模
1. Introduction Insert is one of the most widely used relay parts of our plant. The parts of Fig. 1 are made of brass H62 and 1.2mm thick. The original stamping process was ① blanking and ⑦ flattening. Because it is a single piece of two processes, parts size consistency is not good, resulting in the flattening process, the parts positioning difficulties, the production efficiency is low, can not meet the production needs, so we design a set of six-position progressive die two processes in a Set of molds to complete. 2. Layout Design Through analysis, the parts shoulder, notch and shoulder slightly change the size of the well does not affect the use of parts, according to its structural characteristics, Figure 1 is modified to Figure 2, and the original layout Form Figure 3 is designed as shown in Figure 4, the process is: a punching hole and cut aside the side of the waste; two stations cut the other side of the waste; punching three-position punch; four or five positions flattening; six workers Bit blanking. 3 mold structure and parts processing characteristics Figure 5 for the mold structure.
