我厂生产的电话机接线头(见图1)几何形状虽不复杂但是件小,数量大,如按落料后再分别压凸、打弯的加工工艺,工作效率很低,且质量不能保证。1977年我们试制成功了一付落料压凸压弯连续模,提高了工作效率。 一、模具结构及工作过程:该模(见图2)上模部分由落料凸模16,压弯凸模(带压凸)4,侧刃凸模3组成。下模仅有落料及压弯凹模14,和托料芯15。此外为完成零件在压弯成形后及时退料附加了回拨退料销18,活顶块7,退料勾6组成退件装置。当凸
I plant the production of telephone terminals (see Figure 1) Although the geometry is not complicated, but a small, large number, such as by blanking and then embossing, bending process, the work efficiency is very low, and the quality can not be guaranteed . In 1977, we successfully produced a series of blanking embossing and compression bending continuous mold, improve work efficiency. First, the mold structure and working process: The mold (see Figure 2) part of the die by the blanking punch 16, bending punch (with embossing) 4, 3 punch-side punch. The lower die only blanking and bending die 14, and care core 15. In addition to complete the parts in the bending after the formation of a timely return of the back-off ejector pin 18, the top block 7, the return hook 6 form the return device. When convex
