摘 要
冷冲模是广泛运用的模具之一，种类包括冲孔模、落料模、弯曲模、拉深模等，近年来冷冲模的应用越来越广泛。冷冲压具有成本低，产品质量稳定，能加工多种性能，状态的零件。同时它的应用和普遍也受到模具寿命和生产安全等方面的制约。通过熟悉各类模具的加工特点及内部结构，完成模具总体结构分析；随后作者进行毛坯尺寸、排样、工序尺寸、冲压压力、压力中心、模具工作部分尺寸等工艺计算，力争以最好的性价比设计了模具各零件的结构及装配关系，在此基础上确定模具的外形，完成了装配图和非标准的零件图。

Abstract
Cold punching mould that is used extensively among the all kinds die ,including punching hole mould, blanking die, bending mould, crooked model, conical die etc., The application of the cold punching die is more and more extensive in recent years. It is with low costs that there is the cold punchingly, product quality is steady, can process many kinds of performance , Part of the state. Its application and generallying receive the restriction in life-span of the mould and production safety,etc. at the same time . Author of this text proceed from rationality of the craft, analyse electrical machinery charcoal pastes up the structure of the shelf , And then pass the processing characteristic familiar with all kinds of moulds and inside structure, Finish the ensemble architecture analysis of the mould ; Author carry on blank size, arrange kind, process size, punching pressure, pressure in the center afterwards, mould work some size,etc. craft calculate, Strive to design the structure of every part of the mould and assembly relation with the best cost performance, Confirm the appearance of the mould on this basis, has finished the installation diagram and non-standard part picture.
