我厂试制的产品很多,因此需要设计各种形式的模具结构。下面以弧角零件为例,介绍其工艺分析和冲裁模的设计方案选择及弯曲模的改进情况,供从事模具工作的同志参考。图1所示的是对称形的弯曲件,它的展开图和主要尺寸如图2所示。 I trial a lot of products factory, it needs to design various forms of mold structure. The following parts to the arc angle, for example, describes the process analysis and blanking die design options and the improvement of bending mode for the work of the comrades engaged in reference. Figure 1 shows a symmetrical curved part, its development and main dimensions shown in Figure 2.
