摘 要
冷沖模是廣泛運用的模具之一,種類包括沖孔模、落料模、彎曲模、拉深模等,近年來冷沖模的應用越來越廣泛。冷沖壓具有成本低,產(chǎn)品質量穩(wěn)定,能加工多種性能,狀態(tài)的零件。同時它的應用和普遍也受到模具壽命和生產(chǎn)安全等方面的制約。本文作者從工藝的合理性出發(fā),分析了電機炭刷架的結構,精度特點,以及在加工過程中的控制點,然后在滿足加工精度的基礎上充分考慮節(jié)約成本確定了電機炭刷架最優(yōu)化的沖裁加工工序;緊接著通過熟悉各類模具的加工特點及內(nèi)部結構,完成模具總體結構分析;隨后作者進行毛坯尺寸、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算,力爭以最好的性價比設計了模具各零件的結構及裝配關系,在此基礎上確定模具的外形,完成了裝配圖和非標準的零件圖。最后確定壓力機類型及主要參數(shù)。

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 , Precision characteristic, and the control point in the course of processing, Consider and economize cost confirm electrical machinery charcoal brush blanking that shelf optimizes most process the process fully on the basis of satisfying the machining accuracy; 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. Confirm the type of the press and main parameter finally.
