加工如图1所示要有一定彈性的零件时,一般是用2～4毫米薄銅板冲制而成。但在中小型厂往往由于沒有大型的冲压設备而感到困难,所費工时很大。如采用图2所示的方法,只要制备一块底模和一把滚刀就可以了。 Processing as shown in Figure 1 to have some flexibility when the parts are generally made of 2 to 4 mm thin copper stamping. However, small and medium-sized factories often experience difficulties due to lack of large-scale stamping equipment, which requires a lot of man-hours. As shown in Figure 2 using the method, as long as the preparation of a bottom mold and a hob on it.
