对定位板零件的冲压工艺进行了分析,改用冲孔—整孔—落料连续冲压工艺,可明显提高工件质量及生产率。
With the analysis of punching technology of locating plate, punching hole-mending hole-blanking continuous punching technology can improve part quality and production efficiency greatly.
落料凸模内装有导正销,保证了工件上孔和外形的相对位置准确,提高了加工精度。
Blanking punch contents is a derivative sales, and guarantee the workpiece and the shape of the holes in the relative position accurately, improve processing accuracy.
所以该工序的方法第一步是先由浅拉深,第二步完成冲孔工序,第三步是边孔处的弯曲,最后是落料的工作。
So the process of the first step is the light and dark, the next step through a process towards, the third step is to edge in a curved, the end of the work was.
