工件如图1所示,在距轴端一定距离上需钻一孔。制做钻模时,有两种方案可选择。 1.简易整体钻模 钻模结构如图2所示,可以采用45钢或T8钢局部火焰淬火,也可以配钻套使用。钻模以轴端半圆面定位,由于钻模体定位端面下半部分铣削成敞开形式,既便于每次钻削后废屑的 The workpiece shown in Figure 1, at a distance from the shaft end to be drilled a hole. When making a drill, there are two options to choose from. 1. Simple overall drilling die structure shown in Figure 2, you can use 45 steel or T8 steel local flame quenching can also be used with drill sleeve. Drill to the shaft end of the semicircular positioning, due to the lower half of the drilling body positioning end face milling open form, not only for each after drilling debris
