1、后侧导柱冲孔落料模设计，体现了典型复合模具设计的要求，内容与方向。通过工艺分析，工艺方案的确定，确定了模具设计的方向，对毛坯尺寸的确定，计算冲裁力，来计算压力屮心，选择压力机和压力机的吨位。设计中运用了冲裁工艺及模具设计的基础知识。首先，分析了板材的性能要求，为选去模具的类型做了准备，同吋，也为凸，凹模的材料有了依据。后分析冲裁件的特征，确定了模具设计参数，选择其他零件及卸料装置。也为凸、凹模尺寸的计算还有零件的加工工艺有了依据。在V形弯曲模设计，体现了典型V形弯曲模的设计要求、内容及方向，有一定的设计意义。通过对该零件模具的设计，进一步加强了设计者对弯曲模设计的基础知识
2、的了解与掌握，为设计更复杂的弯曲模具做好了铺垫和吸取了更深刻的经验。木设计运用弯曲成型工艺及模具设计的基础知识，首先分析了板材的性能要求，为选取模具的类型做好了准备；然后计算了弯曲件的弯曲力，便于选取压力机吨位及确定压力机型号；最后分析了弯曲件的特征，确定模具的设计参数、设计要点及顶出装置的选取。关键词：复合模凸模凹模弯曲模ABSTRACTThisdesigntopicisThepiercinganddiedesignoftheguidepininthesideback,inthepersonofthetypicalmodelThepiereingdiedesignofr
