我厂某产品零件“冷凝盘”,在成形后要冲制三种规格共计46个卡爪(见图1)。卡爪形状呈圓头梯形,并要求弯曲成与零件主体表面垂直,以供装配零件用,因此各卡爪之间的相对位置要求比较高。 根据零件工艺的可能性,我们在设计模具时决定采用卡爪切口和弯曲一次成形的复 I plant a product parts “condensate plate”, after forming in three types of punching a total of 46 claws (see Figure 1). The shape of the claw is round trapezoidal and requires bending to be perpendicular to the surface of the main part of the part for the purpose of assembling the parts. Therefore, the relative positions among the claws are relatively high. According to the possibility of the part process, we decided to design the mold using the jaws incision and bending a complex
