1、 落料、正、反拉深模具 课程设计 系 别：材料工程学院 专 业：模具设计及制作 学 号： 姓 名： 指导教师： 2012 年 11 月 落料、正、反拉深模具课程设计 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落料、正、 反拉深的模具。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
2、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。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 2 ABSTRACT As Chinas industrial continuously development, mou

Composite die on the structure adopted the form of dress, calculated the blanking, are drawing and FanLa deep working portion size. To mould height on the determination of reasonable, but also
6、 to design the mould of the main parts blanking die, die and punch, FanLa deep punch, FanLa deep concave die, die fixed plate, etc. Lists the required detailed list of mould parts, and gives a reasonable assembly drawing. Because of the depth of the deep drawing greatly, the press of motor has also carried on the power check and puts forward the lubrication additional process, can make the drawing complete. Finally, the mould a main part guide sleeve of a simple processing technology
