1、摘要随着中国工业不断地发展，模具行业也显得越来越重要。本论文便是设计加工空气滤清器壳的模具。首先对加工零件进行了加工工艺和结构工艺的分析。通过计算毛坯尺寸和拉深系数提出了四种方案，最后确定采用落料、正反拉深复合模。对模具的排样做出了合理的布置，使材料利用率达到较高的水平。计算了冲压过程中所需要的各种冲压工艺力，包括落料力、卸料力、压边力、拉深力、顶料力等，并对压力机进行了合理的吨位初选。复合模在结构上采用了正装的形式，计算出了落料、正拉深和反拉深工作部分的尺寸。对模具的闭合高度进行了合理的确定，还设计出模具的主要零件落料凹模、凸凹模、反拉深凸模、反拉深凹模、凹模固定板等。
2、列出了模具所需零件的详细清单，并给出了合理的装配图。由于拉深的深度较大，对压力机的电机也进行了功率校核并提出了润滑的附加工序，能使拉深顺利完成。最后对模具的一个主要零件导套进行了简单的加工工艺路线的制定。本设计对于采用单动压力机进行正反拉深具有一定的参考作用。关键词毕业论文；模具设计；复合模；正反拉深ABSTRACTDevelopsunceasinglyalongwiththeChineseindustry,themoldprofessionalsoappearsmoreandmoreimportantly.Thepresentpaperthenisdesignsthep
