设计说明书摘要分析了冲压件的结构和成形工艺，计算了毛坯尺寸和冲压力。为了提高弯曲件的生产效率，设计了集三工序为一体的落料弯曲冲孔复合模的结构，经过工艺分析、结构设计，论证了其可能性，保证了制品的质量。在模具设计中,为了提高速度和效率,充分利用已经掌握的知识和资源。利用曲面设计功能快速求出曲面的面积。利用冲模设计手册软件版快速设计冲压模具,并对模具的强度进行检验。实践证明,确实提高了设计的速度和效率。本模具设计中,由于卸料力较大,采用了组合弹簧力较大的优点解决了这一问题。在模具结构中,用顶板做凸模的定位元件,由于配合定位的距离小,容易造成凸模的折断,因而设计了凹模导向凸模,增强了凸模的强度。关键词：；冲孔；弯曲；落料复合模；模具结构AbstractThestructureandprocessingpropertyofbellowsoilconservatorendcoverfortransformerswereanalyzed.Theblankdimensionsandpressingforcewerecalculated.Thecompounddieofcut-tandem-punchcombinedwiththreeproceduresisdesignedinordertoimprovetheproductionofendcover.Thearticleprovesitsavailabilitythroughtechnologicalanalysisandstructuraldesigntoguaranteeproducts’quality.Inmolddesign,inordertoimprovepaceandefficiency,fullyutilizeknowledgeandresourcethathasalreadybeengrasped.UtilizePro/Ecurvedsurfacedesignfunctionask,produceareaofcurvedsurfacefast,utilizethedesignmanualsoftwareeditionofthetrimmingdietodesignandpressthemouldfast,andtheintensitytothemouldisexamined.Practicehasproved,havereallyimprovedpaceandefficiencydesigned.Inthismolddesign,becauseofunloadmaterialtobestrengthrelativelyheavy,adopt,makeupspringloudadvantagesolvethisproblem.Inthemouldstructure,makethelocalizationcomponentoftheprotrudingmouldwiththeroof,thedistancemakingareservationislittlebecauseofcooperating,apttocauseprotrudingruptureofmould,designconcavemouldpour,toprotrudingmould,strengthenprotrudingintensityofmould.Keywords:cut；tandem；punch；compounddie；diestructure目录摘要........................................................................1Abstract......................................................................21绪论.....................................................................92模具设计..................................................................103模具类型的确定............................................................124冲裁间隙的选用............................................................145工艺计算..................................................................155.1材料排样及材料利用率的计算........................................155.1.1材料排样的选用原则........................................165.1.2确定板料规格和裁料方式....................................176计算冲压力................................................................187模具压力中心的确定........................................................197.1模具压力中心的确定.................................................198计算凹凸模刃口尺寸........................................................209冲裁及弯曲的部件及零件设计................................................2210压力设计的选择............................................................3011模具经济以及技术上的分析..................................................31结论.......................................................................32致谢.......................................................................33参考书目.....................................................................341绪论作为一个即将毕业的模具工程专业的学生来说...
