圆筒型件模具毕业设计说明书

武汉科技大学本科毕业设计I摘要在本文中，我们设计了一套冲孔，落料，拉深复合模。文章简要介绍了当前冲压模具的发展形势，其未来发展趋势。文章首先对加工零件进行工艺分析，经过分析和对比，采用冲孔，落料，拉深工序，经过冲裁力、顶件力、卸料力等计算，确定压力机的型号。再分析对冲压件加工的模具适用类型，选择所需设计的模具。得出需要设计的模具类型后，将模具的各工作零部件设计过程表达出来。在设计说明书的第一部分，主要叙述了冲压模具的发展状况，说明了冲压模具的重要性与本次设计的意义，接着是对冲压件的工艺进行分析，确定了工艺方案。第二部分，设计零件排样图，完成了材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算，为选择冲压设备提供依据。最后是主要零部件的设计和标准件的选择。设计模具零件图和装配图，以及模具的成型。关键字：复合模具；冲压模具；冲压设备；冲孔；落料；武汉科技大学本科毕业设计IIABSTRACTThisdesigncarriesonblanking,piercinganddrawingcompounddiesdesign.Throughaccessingtoinformations,andanalyzingthetechnologicpropertiesofprocessingparts,Wedecidetocarryonblanking,piercinganddrawingprocesses.Aftercalculatingthequantitativevalueoftheblankingforce,thekickingforceandthestrippingforce,Weselectetheappropriatepressequipment.Analyzingofthestampingdiesforprocessingtheapplication,toselectthedesiredtypeofmolddesign,thenWeexpressthedesignprocessoftheworkingparts.Inthefirstpartofthedesignspecification,Thearticlebrieflyoutlinesthepressdieatpresentdevelopmentcondition,Illustratestheimportanceofstampingdieandthesignificanceofthisdesign,then,thearticleanalysisestheprocessofstamping,afterthat,weidentifythetechnologyprogram.Inthesecondpart,Wedesignparts’layoutdiagrams,calculatetheutilizationofmaterialandthemagnitudeofedgeblankingprocess,toprovideabasisforselectingpressequipment.Inthelastpart,Webriefiydesignthemajorcomponentsandselectstandardparts,andalsodesignthegraphsofmoldpartsandthegraphsofdieassembling,andtheformingofthemold.KEYWORDS:Compounddies;Pressmold;Pressequipment;Piercing;Blanking武汉科技大学本科毕业设计I设计任务书设计题目：罩落料、冲孔、拉深复合模设计设计要求：1.按要求确定冲压工艺方案；2.排样设计与计算；3.总体方案分析与设计；4.冲压工艺计算及模具关键结构设计,计算；5.模具总体及零部件设计与绘图；6.编写设计说明书设计进度要求：第四周：导师见面，借参考资料，查阅文献；第五-六周：外文翻译，毕业实习报告；第七周：检查外文翻译，毕业实习报告，开始准备毕业设计；第八周：完成总体工艺方案的分析和确定；第九周：完成工艺计算和模具关键结构方案设计；第十周：完成模具总体结构设计，选择合适的成型设备；第十一-十二周：完成模具零件的详细设计；第十三-十四周：编制模具零件制造工艺方案，撰写毕业设计说明书；第十五周：完成所有设计文档，资料的收尾工作，准备答辩；第十六周：答辩。指导教师（签名）：武汉科技大学本科毕业设计I目录摘要..............................................................I设计任务书........................................................I1材料分析和模具结构的确定........................................11.1冲压件工艺性分析：..................................................................................................................11.2冲压工艺方案的确定：..............................................................................................................21.3模具结构形式的确定..................................................................................................................32主要设计计算....................................................52.1毛坯尺寸计算..............................................................................................................................52.2确定拉深次数..............................................................................................................................62.3材料利用率...................................................................................................................................62.4确定排样方式..............................................................................................................................72.5各工序的冲压力计算..................................................................................................................82.6压力中心的确定.........................................................................................................................102.7工作零件刃口尺寸计算............................................................................................................113主要零部件的设计...............................................133.1工作零件的结构设计................................................................................................................133.2支撑固定及卸料零件................................................................................................................174其他零部件的设计与选用.........................................204.1弹性元件....................................................................................................................................204.2卸料螺钉....................................................................................................................................204.3挡料销........................................................................................................................................204.4模架及其他零部件的选用........................................................................................................205模具的总体设计.................................................215.1模具类型的选择........................................................................................................................215.2定位方式的选择........................................................................................................................215.3卸料、出件方式的选择............................................................................................................215.4导向方式的选择........................................................................................................................216模具的总装图...................................................227模具零件加工工艺..........
