弯曲成形。在设计过程中，我们先设计了弯曲模，然后在根据制件展开尺寸计算出了冲孔落料复合模的模具刃口尺寸并设计出了复合模的其他部分。在设我们先对冲裁件的工艺性进行分析，分析其孔间距以及孔边距是否满足冲孔落料复合模的要求，进而最终确定冲裁工艺方案。接下来，我们计算了送料步距、条料宽度等参数。在确定了冲裁力以及压力中心等参数后我们初步选出了压力机，待模具结构设计完毕后再验证所选压力机是否合适或是进一步确定教为合适的压力机。凸凹模以及凸模刃口尺寸由制件的尺寸以及凸、凹模间隙决定，而凸、凹模间隙则由制件的材料及其厚度决定，依据这种思路，我们首先根据制件的材料及其厚度确定间隙的最大和最小值，然后根据落料以凹模为基准，冲孔以凸模为基准的计算原则分别计算出凸凹模和凸模的刃口尺寸，然后根据其他条件与参数设计出凸凹模和凸模的其他结构尺寸。关键词冲孔落料复合模具弯曲模圆角半径凸凹模
