哈尔滨工业大学华德应用技术学院毕业设计(论文)I冲孔拉伸复合模设计摘要本论文主要是对落料,拉深,冲孔翻边复合模而做的设计。这套复合模不但节约了原材料,为工厂带来了利益和效率,更主要的是它把这几个原本不容易合在一起的制造工艺通过特殊装置实现了。很大程度的提高了工作效率,并把原来一套以上才能完成的工艺用这套复合模完成了。此论文主要阐述了我国模具现状和发展趋势、对零件的工艺分析、模具结构的设计、模具装配与部装图的设计。其中工艺分析对零件的特性和材料性能做了简单的介绍,工艺计算主要是为设计选件打基础,通过大量的计算来确定一些标准件选择的尺寸和压力机的确定等。经过第二章计算和分析后进行模具结构的选择,其中包括标准件的选择和非标准的设计等。要做到标准件的选择正确以及非标准件的设计合理。最后用CAD绘制出模具的装配图和部装图,阐明装配时需要注意的事项。关键词冲压工艺模具CAD哈尔滨工业大学华德应用技术学院毕业设计(论文)IIPunchingdrawingCompoundDieAbstractThispapermainlyforblanking,deepdrawing,punchingdoneflangingcompounddiedesign.Thecompounddiehasnotonlysaverawmaterials,thefactoryhasbroughtbenefitsandefficiency,moreimportantisthatitisnoteasytoputtogetherafeworiginalmanufacturingprocessachievedthroughaspecialdevice.Alargedegreeofimprovedefficiency,andtomorethanonesettocompletetheoriginalprocesswiththissetofcompositemoldiscomplete.ThispaperexpoundsthestatusquoanddevelopmenttrendofChinasmoldonthepartoftheprocessanalysis,moldstructuredesign,moldassemblyandtheMinistryofloadingmapdesign.Inthecraftanalyzethecharacteristicsofpartsandmaterialstodoasimpleintroductiontotheperformance,technicalcomputingismainlylayingthefoundationforthedesignoption,throughalargenumberofcalculationstodeterminethesizeofsomestandardpartsselectionandpressOKandsoon.Afterthesecondchapterafterthecalculationandanalysisofdiestructureoftheoptions,includingthechoiceofstandardpartsandnonstandarddesign.Toachievethecorrectchoiceofstandardparts,aswellasrationaldesignofnonstandardparts.Atlast,drawingoutthemoldassemblyCADdrawingsandinstallationdiagramMinistrytoclarifyassemblyrequiredattention.KeywordsstampingprocessdieCAD哈尔滨工业大学华德应用技术学院毕业设计(论文)III目录摘要.................................................................................................................IAbstract..........................................................................................................II第1章绪论...................................................................................................11.1国内模具的现状和发展趋势...............................................................11.1.1国内模具的现状...............................................................................11.1.2国内模具的发展趋势.......................................................................21.2国外模具的现状和发展趋势..............................................................31.3模具的分类和占有量..........................................................................41.4课题研究的目的及论文主要内容.......................................................5第2章零件的工艺性分析...........................................................................72.1零件的特性..........................................................................................72.1.1零件的工艺性....................................................................................72.1.2零件的工艺分析................................................................................72.1.3零件的材料分析................................................................................82.1.4零件的三维图....................................................................................82.2冲压工艺方案的拟定...........................................................................92.2.1确定加工工序....................................................................................92.2.1.1确定拉深次数.................................................................................92.2.1.2确定翻边次数...............................................................................102.2.1.3工艺方案的确定...........................................................................102.2.2模具类型..........................................................................................112.2.3操作与定位方式..............................................................................112..4卸料与出件方式................................................................................112.2.5模架类型及精度..............................................................................112.3本章小结.............................................................................................11第3章冲裁力的计算、压力机的选择.....................................................123.1排样图的确定....................................................................................123.1.1毛坯尺寸的确定..............................................................................123.1.2搭边值的确定..................................................................................12哈尔滨工业大学华德应用技术学院毕业设计(论文)IV3.1.3条料宽度与导料板间距..................................................................133.1.5排样图的设计..................................................................................153.2冲裁力的计算.....................................................................................153.2.1落料工艺计算..................................................................................153.2.2拉深工艺计算..................................................................................163.2.2.1确定修边余量...............................................................................163.2.2.2拉深力的计算...............................................................................163.2.3冲孔工艺计算...
