我厂生产的同步发电机中,励磁机的端罩和发电机端盖上的百叶窗是数排半透的凸孔,其零件形状如图1所示。此类零件的加工,通常叫做“切口”。一般都是用刚性冲头与凹模的相对运动而成形的。其模具形状如图2所示。上为凸模,下为凹模。工作时,除刃口部分将板材剪断外,其弧面部分还必须起到成形

I plant the production of synchronous generators, exciter end shields and generator cover the blinds are several rows of semi-permeable convex hole, the shape of the parts shown in Figure 1. The machining of such parts, often called “cutouts.” Generally rigid punch and die with the relative movement and shape. The mold shape shown in Figure 2. On the punch, under the die. Work, in addition to the cutting edge of the plate cut, the arc must also play part of the shape
