在加工冲裁模的凹模时,如果没有专用设备,一般都是用连钻法去除凹模当中废料。这个方法一般是沿凹模工作轮廓线钻孔,孔之间留有较小的余量,以后用凿子把余量凿去而敲出中间废料;或者孔间距稍小于钻头直径,用低碳圆钢塞满已钻透的孔,然后钻另一行孔,最后敲出废料。以上这些方法效率都比较低。这里介绍工人们创造的一种较好的方法。这方法 When processing the die of the blanking die, if there is no special equipment, the scrap in the die is generally removed by a continuous drilling method. This method is generally drilled along the working contour line of the die, leaving a small margin between the holes. After that, the chisel can be used to cut the residue to knock out the intermediate scrap; or the hole spacing is slightly smaller than the drill diameter, using a low carbon circle. The steel is stuffed with holes that have been drilled through, then drilled in another row of holes and finally knocked out the scrap. The above methods are relatively inefficient. Here is a good way to create the workers. This method
