在生产中对尺寸形状相同、方向相反的工件(见图1),可用一套模具拉制而成(如图2所示)。它与一般拉深模的不同点是:①增加了垫板2;②凸凹模两面都有圓角;③凸凹模上所有的螺孔和销孔都是通的。使用时,模具先按图2装配好拉深第一个工件。在拉深第二个工件时,应将凸、凹模、退料板、卸料板等有关零件翻过来装配好后再进行压制。这
In the production of the same size and shape, the opposite direction of the workpiece (see Figure 1), a set of mold can be drawn from (as shown in Figure 2). It is different from the general drawing die is: ① increased plate 2; ② punch on both sides have rounded corners; ③ punch and die on all the holes and pin holes are through. Use, the mold according to Figure 2 assembled deep drawing the first workpiece. In the drawing of the second workpiece, the convex, concave die, stripper, stripper and other related parts turned over to assemble and then suppress. This
