图示是一种制造钢丝钩的冲模,在一次冲程中,能完成下料和两端成型工序—一端卷圆,另一端弯成直角该模具的槽型支架焊接在底座16上,支架上安装有小齿轮和固定销轴。操作程序如下:钢丝6从支架5右侧送进,到达左侧的定位挡块4为止。当冲头1下降时,连接在冲头上的齿条2驱动小齿轮3,小齿轮上的偏心销就强迫钢丝圈绕小齿轮中心的销轴卷成圆环。同时,冲头右边的切
The figure shows a die for making a wire hook that can complete the blanking and the two-end forming process in one stroke - one end of the die is rounded and the other end is bent at a right angle. The slotted bracket of the die is welded to the base 16, Pinion and pin. The operating procedure is as follows: The wire 6 is fed from the right side of the carriage 5 to the left of the positioning stop 4. When the punch 1 descends, the rack 2 connected to the punch drives the pinion 3, and the eccentric pin on the pinion forces the wire loop to roll around the pin of the center of the pinion. At the same time, the punch to the right of the cut
