一般冲裁件都是用平面冲裁法,而图1所示零件需用斜冲的方法,才能达到图纸的要求。以前,我们对该零件的生产工艺是:先下料,用油压机成型(见图2),再用气割枪割成45°角(如图3)。由于气割面高低不平,角焊达不到要求。于是就用砂轮磨平,再一个个对接。这样,不但工作效率低,而且劳动强度大。针对上述问题,我们先用平面冲裁法,即把45°角展开(图4),按其形状冲裁,然后放在油压机上压成
General blanking pieces are used plane blanking method, and the parts shown in Figure 1 need to use oblique method, in order to achieve the requirements of the drawings. In the past, our production process for the part was first blanking, forming with a hydraulic press (see Figure 2), and cutting with a gas torch to a 45 ° angle (Figure 3). As gas cutting surface rugged, not meet the requirements of fillet welding. So polished with a grinding wheel, and then one by one docking. In this way, not only is it inefficient and labor-intensive. In response to the above problems, we first use the plane blanking method, that is, 45 ° angle expansion (Figure 4), according to the shape of blanking, and then on the hydraulic press
