带法兰圆筒拉深冲孔复合模的设计

摘要

模具工业是国民经济的重要基础工业之一。

模具是工业生产中的基础工艺装备，是一种高附加值的高精密集型的产品，也是高新技术产业化的重要领域，其技术水平的高低已经成为衡量一个国家制造业水平的重要标志。

而复合模生产效率较高，适合大规模的工业生产。

本次设计对典型的复合模中包含的四种冲压工序落料、拉深、冲孔与切边变形特性进行了分析，并从模具结构的角度对各工序变形影响因素进行了讨论。

运用大学期间所学的专业课程知识、理论和毕业实习中学到的实践知识，正确地解决复合模设计中工艺分析、方案论证等模具结构设计等问题，充分利用与本复合模设计有关的各种资料，做到科学合理地熟练应用。

同时提高自己绘图能力，通过对带法兰圆筒拉深冲孔复合模的设计，巩固对模具理论的掌握，增强动手的能力，培养严谨科学态度，并且也达到理论与实际相结合的目的。
