摘 要
冷沖模是廣泛運(yùn)用的模具之一，種類包括沖孔模、落料模、彎曲模、拉深模等，近年來冷沖模的應(yīng)用越來越廣泛。冷沖壓具有成本低，產(chǎn)品質(zhì)量穩(wěn)定，能加工多種性能，狀態(tài)的零件。同時(shí)它的應(yīng)用和普遍也受到模具壽命和生產(chǎn)安全等方面的制約。通過熟悉各類模具的加工特點(diǎn)及內(nèi)部結(jié)構(gòu)，完成模具總體結(jié)構(gòu)分析；隨后作者進(jìn)行毛坯尺寸、排樣、工序尺寸、沖壓壓力、壓力中心、模具工作部分尺寸等工藝計(jì)算，力爭以最好的性價(jià)比設(shè)計(jì)了模具各零件的結(jié)構(gòu)及裝配關(guān)系，在此基礎(chǔ)上確定模具的外形，完成了裝配圖和非標(biāo)準(zhǔn)的零件圖。

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.
