该零件的弯曲方法一般有两种:其一是先冲压R1.7以外的形状,再冲压R1.7,由两副模具来完成。这种方法模具制作简单,凸模、凹模易修正,但第二道工序定位困难,工效低。另一方法是一副模具完成成形,即一次就将工件纵横弯曲成形,这样操作定位方便,工效较高,但模具制造较复杂。模具设计既要确保加工零件质量,又要讲究生产效率。为此采用第二种方法,设计了一副带侧斜楔的纵横向同时作用的弯曲模。结构如图2所示。经过半年多的生产实践,取得了很
The bending method of the part generally has two kinds: one is the shape of the other than the first stamping R1.7, and then stamping R1.7 by the two molds to complete. This method of making a simple mold, punch, die easy to amend, but the second process positioning difficulties, low efficiency. Another method is to complete a mold forming, which will be a vertical and horizontal bending of the workpiece shape, so easy to operate and positioning, high efficiency, but the mold manufacturing more complicated. Mold design not only to ensure the quality of parts processing, but also pay attention to production efficiency. For this purpose, the second method is adopted to design a bending mold with both longitudinal and transverse functions of side wedges. Structure shown in Figure 2. After more than six months of production practice, made very
