摘要 冲压模具在实际工业生产中应用广泛。在传统的工业生产中，工人生产的劳动强度大、劳动量大，严重影响生产效率的提高。随着当今科技的发展，工业生产中模具的使用已经越来越引起人们的重视，而被大量应用到工业生产中来。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。 本文对冷冲压技术的分类、特点及发展方向作了简略概述；简述了冲压零件的形成原理、基本模具结构与运动过程及其设计原理；对典型的冲压件模具进行了设计：带凸凹模的拉伸冲孔复合模设计、落料、拉深、冲孔、翻边复合模设计、零件拉深模和小孔翻孔模。 冲压模具的设计充分利用了机械压力机的功用特点，在室温的条件下对坯件进行冲压成形，生产效率提高，经济效益显着。 本文介绍的模具实例结构简单实用，使用方便可靠，对类似工件的大批量生产具有一定的参考作用。 关键词冲压模具机械制造模具设计冲裁拉深 Left bracket seco
