1、 学号： 毕业设计毕业设计 题 目： 挡板工艺规程编制及落料冲孔模设计计 作 者 届 别 系 别 机械与电子工程系 专 业 机械制造及自动化 指导老师 职 称 高级工程师 完成时间 2011.05 I 摘 要 冷冲压是利用安装在压力机械上的冲模对材料施加压力， 使其产生分离或塑 性变形，从而获得一种零件的一种压力的加工方法。通常是在常温下进行，所以 成为冷冲压。冲模是将材料加工成所需装备的一种工艺设备。冲模在冷冲压中至 关重要。本论文分析了,挡板落料冲孔模具设计，介绍了落料冲孔模具设计要点， 计算了落料冲孔模的冲压力，按照零件的尺寸设计了挡板落料冲孔模具，阐述了 凸，凹模具设计及其结构。合理的
2、对工艺对简化模具结构，减少模具数量，降低 成本，提高制件质量有重要意义，对简单冲压件的批量生产找到一条适用的解决 方案。 关键词：落料冲孔；模具设计；挡板 II Abstract Stamping is the use of machinery installed in the pressure of the die pressure on the material to produce a separation or plastic deformation, and thus obtain a part of a pressure processing method. Is usually
3、carried out at room temperature, so a cold stamping. Die is processed into the material and equipment required for a process equipment. Stamping die in the cold is crucial. This paper analyzes; floor fan extension of pre-nets with mold design and mold manufacturing process extension, introduced the
4、extension of die design elements to calculate the pressure of the extension of the impulse model, according to the size of components designed to stand fan before the network cover mold, illustrates the convex, concave mold design and top-feeding device, discharge plate. A reasonable simplification of the process on the die structure, reducing the number of mold, reduce costs, improve the quality of workpiece importance of the mass production of simple stampings to find an appropriate
