冲压模具毕业设计-翻边模的设计

摘要随着科学技术的发展，对压铸件产品的安全性和造型美观的要求不断提高。根据使用的不同，对零件的质量评价有所不同。如何生产出高质量的零件，对节约材料、能源和提高经济效益都有很大的意义。分析了灯罩这种形状复杂、壁薄零件的结构特点。针对压铸中易形成裂纹、拉伸不足等缺陷的工艺特性，在根据理论分析的要求和数据的基础上运用Sol-idworks软件进行三维实体造型，并对未知的尺寸进行规定。然后利用这个三维实体计算零件的质量，在Solidworks软件中根据零件的质量来设计出的预定厚度的圆形坯料板材直径。根据所得的直径来确定原始坯料的一些尺寸，为后续的设计和研究提供一定的依据。同时利用Solidworks软件或其它三维软件对冲压模型可行性进行分析和设计，利用软件进行灯罩成型模的相关模具设计。通过运用Solidworks软件，同时结合逆向造型的方法来设计相对应的模具，为了实现零件的成型，本人利用Solidworks软件设计四副模具，分别设计落料模、液压模、翻边模和卷边模，使原材坯料经过以上四副模具的加工来得到所要求的零件。研究成果是得到四副模具三维模型和相对应的二维CAD图尺寸图。结论是得到所设计的零件的四副模具的相关数据，如果在实际生产中，可能运用的话，再添加其它相关的数据，可以成批生产。最后，对本次的模具设计进行总结。关键词：落料；液压；翻边；卷边AbstractWiththedevelopmentofscienceandtechnology,Die-castingproductsforsafetyandaestheticshapesrising.Accordingtodifferentuse,Evaluationofthequalityofpartsaredifferent.Howtoproducehigh-qualityparts,tosavematerials,energyandincreaseeconomicefficiencyhasgreatsignificance.Analysisofthecomplexityoftheshadeofsuchashape,thin-walledpartsofthestructuralcharacteristics.Easyfordie-castingintheformationofcracks,lackofdefectsinthetensilepropertiesoftheprocess,andinaccordancewiththerequirementsoftheoreticalanalysisanddatabasedontheuseofSolidworks3Dsolidmodelingsoftware,andtheprovisionsofunknownsize.Thencalculatedusingthethree-dimensionalentities,thequalityofparts,inaccordancewithSolidworkssoftwaretodesignpartsofthequalityofthetargetplatethicknessthediameterofthecircularblank.Accordingtotheoriginalblankdiametertodeterminethenumberofdimensionsforthedesignandfollow-uptoprovideabasisforresearch.Atthesametime,theuseofSolidworkssoftwareorotherthree-dimensionalsoftwaremodelofthestampingfeasibilityanalysisanddesign,useofsoftwarerelatedtoshadeMoldmolddesign.ThroughtheuseofSolidworkssoftware,combinedwiththemethodofreversemodelingofthecorrespondingmolddesign,moldingpartsinordertoachieve,IuseSolidworksMoldDesignfourmolds,respectively,blankingdiedesign,hydraulicmold,flangingandcrimpingdiemold,sothattheoriginalmaterialformorethanfourblankmoldafterprocessingtogettherequiredparts.Researchresultsarethree-dimensionalmodelsoffourmoldsandthecorrespondingsizechartdiagramoftwo-dimensionalCAD.Conclusionisdesignedbyfourmoldpartsoftherelevantdata,ifintheactualproductionmaybeused,thenaddotherrelevantdata,canbemass-produced.Finally,thediedesignofthissummary.Keywords:Blanking;Hydraulic;flanging;Crimping目录摘要Abstract第一章绪论.....................................................................................................................................11.1课题研究的目的和意义............................................................................................................11.2铝挤压材工业的发展现状........................................................................................................11.3该行业的其它相关零件的研究................................................................................................21.3.1薄壁深锥零件的拉伸成形方面的研究.......................................................................21.3.2铝锅冷挤压工艺及模具等类似产品的设计...............................................................21.4本论文研究的基本内容及拟解决的主要问题.......................................................................3第二章总体方案的设计.................................................................................................................42.1设计要求.....................................................................................................................................42.2设计分析和流程.........................................................................................................................52.3对模具结构和机构工作原理的解说.......................................................................................72.3.1对冲裁落料模工作过程和原理的解释说明...............................................................72.3.2对液压模工作过程和原理的解释说明.......................................................................82.3.3对翻边模工作过程和原理的解释说明.......................................................................82.3.4对卷边模工作过程和原理的解释说明.......................................................................8第三章落料模的设计.....................................................................................................................93.1工艺分析计算.............................................................................................................................93.1.1工件的排样方案...........................................................................................................93.1.2工艺力计算和压力机选择.........................................................................................113.1.3对模具工作部分尺寸计算.........................................................................................123.2模具零部件的设计计算..........................................................................................................133.2.1凹模的设计计算..........................................................................................................133.2.2选择标准模架.............................................................................................................143.2.3凹模和下模座的关联设计.........................................................................................14第四章液压模的设计.........
