汽车玻璃升降器外壳.docx

摘要模具工业有“不衰亡工业”之称人们已经越来越认识到模具在制造中的重要地位认识到模具技术水平的高低已成为衡量一个国家制造业水平高低的重要标志并在很大程度上决定着产品质量、效益和新产品的开发能力。本次设计利用CATIA在建模方面的强大能力对汽车玻璃升降器外壳的整套模具进行并装配。通过实体建模系统可以进行快速的概念设计通过定义设计中的不同部件间的数学关系将它们的需求和设计限制结合在一起；基于特征的实体建模和编辑能力使得设计者可以通过直接编辑实体特征的尺寸或通过使用其他几何编辑和构造技巧来改变更新实体。CAD、CAE在设计中的同步使用计算分析与设计同步使设计方案到优化从根本上保证产品质量。关键字：冲压模具实体建模CATIAAbstractModernmouldindustryisknownforneverdeclining.Peoplebegintorealizethegreatimportanceofmouldinmanufacturingandperceivethatthetechnicalstandardofmouldhasbeenregardedasasymbolthatindicatethelevelofthemanufacturinginanation.Furthermoremoulddeterminesthequalityoftheproductsbenefitandthecapabilityofnewproductsexploitingtoagreatextent.ThispapermainlyfocusesonmodelingandassemblingthewholesetmouldswhichareusedtoproducethesheathingofautomobileglassriserbyusingthepowerfulfunctionofCATIAinrespectofmodeling.Speedyconceptualdesigncanbeconductedbysubstantialitymodelingsystemandtheirrequirementandtheprogrammingrestrictswillbecombinedbythemathematicrelationamongdifferentcomponentsinconceptualdesign.Basingonfeaturessubstantialitymodelingandeditingcapacityhelpthedesignerschangingandrenewingsubstantialitybywayofeditingthedimensionofsubstantialityfeaturesdirectlyorothergeometriceditingandconstructingtechniques.ForthesakeofoptimizingdesignplanCADandCAEcanbeusedsimultaneouslyindesigningcalculatinganalysisanddesigningcanbeconductedatthesametime.sothatthequalityoftheproductcanbeensuredattherockbottom.Keywords:presstoolsolidmodelerCATIA目录摘要-1-1.绪论-5-2.零件的冲压工艺性分析-7-2.1零件的工艺性分析-7-2.2冲压工艺分析-7-2.2.1计算毛坯尺寸-7-2.2.2计算拉深次数-8-2.2.3确定各工序拉深的尺寸-9-3.工艺方案的确定-11-4.确定排样、裁板方案-13-5.计算各工序压力、选择压力机-14-5.1落料加第一次拉深-14-5.1.1冲裁力-14-5.1.2卸料力-14-5.1.3拉深力-14-5.1.4压边力-15-5.2第二次拉深：-15-5.2.1拉深力-15-5.2.2压边力-15-5.3第三次拉深兼整形工序
