文档介绍：铁心冲片的冲压工艺与模具设计
摘要
本设计为冲孔、落料的模具。经过查阅资料,首先要对零件进行工艺分析,经过工艺分析和对比,采用冲孔落料工序,通过冲裁力、顶件力、卸料力等计算,确定压力机的型号。再分析对冲压件加工的模具适用类型选择所需设计的模具。得出将设计的模具类型后将模具的各工作零部件设计过程表达出来。
在第一部分分析了工件的材料与冲压工艺,采用复合模具进行加工,然后计算出冲压力,再为工件加工是的排样设计计算出材料利用率保证材料的经济性。在进行压力机的选择。后面为了保证冲件的精度进行凸凹模刃口尺寸的计算。这些都算好后进行绘制模具总装草图,并且书写说明书,以此设计模具各个工作零件的尺寸,保证设计的合格率。在工作零件等都设计完全后,进行绘制正式的零件图与模具总装图,最后进行检查,修改,保证本设计的正确度。

一、冲压工艺分析设计
冲裁件的工艺性是指从冲压工艺方面来衡量设计是否合理。一般的讲,在满足工件使用要求的条件下,能以最简单最经济的方法将工件冲制出来,就说明该件的冲压工艺性好,否则,该件的工艺性就差。当然工艺性的好坏是相对的,它直接受到工厂的冲压技术水平和设备条件等因素的影响。以上要求是确定冲压件的结构,形状,尺寸等对冲裁件工艺的实应性的主要因素。根据这一要求对该零件进行工艺分析。
