小直径不锈钢筒形件拉深CAE分析及模具设计系别：机电学院专业班：材料成型及控制工程2班姓名：张世辉学号：090010228指导教师：李河宗2013年6月河北工程大学毕业设计摘要冲压是利用安装在冲压设备（主要是压力机）上的模具对材料施加压力，使其产生分离或塑性变形，从而获得所需零件的一种压力加工方法。这次拉深是利用模具使10号钢平板毛坯材料变成为开口的空心零件的冲压方法，用拉深工艺可以制成筒形件、阶梯形件、球形、锥形、抛物面形、合形和其他不规则形状的薄壁零件。通过对一个阶梯形筒形件的拉深工艺计算，说明阶梯筒形件的拉深工艺的计算方法。用该方法计算确定的拉深工艺，可以确保多次拉深过程中的拉深过渡形状不被拉断，最终拉出合格的工件。这里介绍了落料拉伸，整形，切边等多套模具。用该方法计算确定的拉深工艺，使得模具设计、加工精度与复杂性不断提高，模具制造工期不断缩短。关键词：筒形件拉深工艺整形切边I河北工程大学毕业设计AbstractSteelpartsofthestampingprocessanddiedesignAbstractTheuseofstampingisinstalledinthestampingequipment(mainlythepress)onthemoldtoexertpressureonthematerialstoproduceplasticdeformationorseparation,toobtainthenecessarycomponentsofapressureprocessingmethods.Drawingisusedtomoldintoaplateof10steelroughopeningsforthehollowpartsstampingmethod,usingdrawingprocesscanbemadetube,ladder-shapedpieces,spherical,cone-shaped,parabolicshape,orotherirregularshapeandthinWallcomponents.Basedonaladder-shapedcylinderofthedrawingprocess,thatladdertubedrawingofthemethodofcalculation.Thismethodisdeterminedbythedrawingprocess,drawingonmanyoccasionstoensurethattheprocessofdrawingtheshapeisnotpulledoffthetransitionandeventuallypulledoutofqualifiedworkpiece.Hereontheblankingstretch,repeatedlydrawing,shaping,trimming,andothersetsofmold.Withthemethodofcalculatingsuredeepdrawingtechnology,makethemolddesign,processingprecisionandcomplexitycontinuouslyimprove,moldmanufacturingcontinuouslyshorteningperiod.KeyWords：CylinderDrawingProcessShapingTrimmingII河北工程大学毕业设计目录摘要......................................................................................................................................................IAbstract..............................................................................................................................................II第一章绪论....................................................................................................................................11.1冲压模具在制造业的地位...................................................................................................11.2冲压模具的历史发展..........................................................................................................11.3国内模具的现状和发展趋势..............................................................................................11.3.1国内模具的现状.......................................................................................................13.2国内模具的发展趋势............................................................................................................31.4圆筒拉深件模具设计与制造方面.............................................................................................41.4.1深圆筒拉深模具设计的设计思路..................................................................................4第二章工艺方案分析及确定............................................................................................................62.1拉深件工艺性分析.....
