1、门窗插销连接件模具设计Door latch connector mold design 专 业:材料成型及控制工程(模具) 姓 名: 指导教师姓名: 申请学位级别: 论文提交日期: 学位授予单位:摘 要冲压模具在实际工业生产中应用广泛。冲压模具的自动送料技术也投入到实际的生产中,冲压模具可以大大的提高劳动生产效率,减轻工人负担,具有重要的技术进步意义和经济价值。在这次设计中,首先运用PRO/E软件的三维造型功能,对零件进行三维造型。对零件进行工艺性分析,大大简化计算并得到精确结果,在此基础上应用AutoCAD绘制零件的二维图纸,以加深对冲裁件、拉深件和成形件结构的工艺性的理解。设定零件的工艺方
2、案,比较工艺方案并确定工艺方案。计算毛坯的尺寸,计算冲裁次数,设定各步半成品的尺寸并绘出工序简图。计算各个工序的工作压力,设计并绘出模具简图,选取各个合适的零件。了解落料模、拉深模、整形模、切边模和冲孔模的特点和需要注意的问题,在模具简图的基础上进行模具结构工艺性分析,进行模具结构设计并选择冲压设备。关键词:级进模; 模具设计; 工艺; 结构设计目录ABSTRACTPunching die has been widely used in industry. More Self-acting feed technology of punching die is also used in prod
3、uction, punching die could increase the efficiencies of production and could alleviate the work burden,so it has significant meaning in technologic progress and economic value. In this design, first we use the 3D software function of PRO/E to create 3D model of the part. During the procedure, the wo
4、rk pieces craftwork character is analyzed, and the work pieces 2D drawings are made by AutoCAD, so that the work piece can be better comprehended. Learn the structural craftwork character of the work piece, so does the drawing and forming craftwork character. Make sure the work pieces craft project,
5、 compare them and make the final decision. Calculate the size of the roughcast and select its shape. Calculate the times of the drawings, make sure the size of the semi-manufactured work piece of every steps, and draw the working procedures sketch. Calculate the every working pressure, design and dr
