过去加工如图1所示的元宝螺母孔时,没有专用工具,是依靠画线找出中心,然后依线冲眼钻孔,效率很低。后来车间里的老师傅林振业同志制造了一种能快速装卡工件的钻模,如图2所示。使用钻模加工,减少了划线工序使生产效率显著提高,并且百分之百的保证了产品质量。组成钻模的主要零件有:手柄1,钻模板2,导盖3,升降托盘4,底座5及 In the past, as shown in Figure 1 ingots nut hole, there is no special tool, is to rely on drawing lines to find the center, and then according to the red line hole drilling, low efficiency. Later, the workshop teacher Lin Zhenye made a rapid installation of the workpiece chuck, as shown in Figure 2. The use of die processing, reducing the scribing process to significantly improve production efficiency, and one hundred percent to ensure product quality. The main components forming the drill are: handle 1, drilling template 2, cover 3, the lifting tray 4, the base 5 and
