我厂过去制造摇臂收割机上的油杯盖(如图1)是采用一付比较复杂的模具,操作不方便,不安全,产量又很低。经过改进,采用一付象图2那样的弯形模,产量就提高1倍左右。这付弯形模如图2所示,结构很简单,操作方便,成形后工件可以由冲头经过漏盘当中脱落下来。冲头和漏盘的结构请看图3、图4。 I plant in the past to manufacture rocker arm harvester oil cup cover (Figure 1) is to use a pair of more complex mold, the operation is not convenient, unsafe, the yield is very low. After the improvement, with a pair of curved die as shown in Figure 2, the output increased by about 1 times. This type of bending mold shown in Figure 2, the structure is very simple, easy to operate, after forming the workpiece can be punched through the drain off them. Punch and drain disk structure, see Figure 3, Figure 4.
