摘 要
模具是现代工业的重要工艺设备，随着科学技术的不断进步，它在国民经济中占有越来越重要的地位，发展前景十分广阔。装备制造业在2007年的迅速发展，尤其是汽车和电子电器产品的高速增长，为模具工业的发展营造了良好的市场环境。本次综合实训设计监控器吊支架的复合冲压模具，从零件的工艺性分析到模具结构的设计再到工艺计算，一直到最后的模具装配图。同时，模具也是机械制造业中技术先进、影响深远的重要工艺装备,具有生产效率高、材料利用率高、制件质量优良、工艺适应性好等特点,被广泛应用于汽车、机械、航天、航空、轻工、电子、电器、仪表等行业。随着我国汽车工业的迅猛发展，汽车性能不断提高，汽车零部件中对高精度、形状复杂锻件的需求量越来越大，锻造新工艺、省材、节能工艺等技术的开发对于新型汽车零件的生产尤为重要。我国冲压模具无论在数量上，还是在质量、技术和能力等方面都已有了很大发展，但与国民经济需求和世界先进水平相比，差距仍很大，一些大型、精密、复杂、长寿命的高档模具每年仍大量进口，特别是中高档轿车的覆盖件模具，目前仍主要依靠进口。
本文主要是以监控器吊支架冲压件为例，设计和制定监控器吊支架冲压件的工艺设计和工艺设备的选择以及冲压模具设计。
