推件固定片级进模设计及其制造工艺

推件固定片级进模设计及其制造工艺I摘要本文主要通过分析对推件固定片零件的冲裁以及弯曲的生产工艺，了解了级进模的总体结构。分析比较了该零件的工艺方案，选定了模具形式是多工位级进模。通过对零件冲压工艺分析、冲孔-落料级进模零件的设计与计算、冲裁件整形、模具安装于调试、以及绘制装配图和零件图。其中还有推件固定片的零件冲压工艺性分析；确定冲压基本工序；排样方案的确定；连续模的送料定位系统的选用；冲裁模具凸凹模刃口尺寸的计算；模具主要零件尺寸计算；冲压力的计算；压力中心的计算；选择冲压设备；冲模的闭合高度；调整模具闭合高度等来研究零件的冲裁。最后校核了冲压设备及确定了模具部件的材料和热处理要求。在模具结构绘制方面，借助于AutoCAD软件，绘制出模具的装配图和非标准件的零件图。本次设计对多次弯曲的零件的级进模设计有一定的深入了解，为日后的模具设计打下了基础。关键词：推件固定片，级进模，模具设计，结构设计推件固定片级进模设计及其制造工艺IIAbstractThispapermainlythroughtheanalysistopushafixedpieceofcuttingandbendingmanufacturingprocess,understandtheoverallstructureofprogressivedie.Analysiscomparedtheprocessingplanofthepartsandthemoldformisselectedmulti-stationprogressivedie.Throughthepartsstampingprocessanalysis,punchingandblankingprogressivediedesignandcalculationofblankingpieces,plasticparts,mouldinstallationdebugging,anddrawtheassemblydrawingandpartdrawing.Withafixedpiecepartsstampingmanufacturabilityanalysis;Basicprocesstodeterminethestamping;Theschemedeterminationoflayout;Continuousmodeselectionoffeedingpositioningsystem;Blankingmouldanddiecuttingedgedimensioncalculation;Diemainpartssizecalculation;Burstpressurecalculation;Calculationofpressurecenter;Choosestampingequipment;Dieshutheight;Adjusttheheightandsoontostudyapartoftheblankingdieclosed.Finallycheckthestampingequipmentanddeterminethemouldpartsmaterialandheattreatmentrequirements.Intermsofthemouldstructuredrawing,withthehelpofAutoCADsoftware,drawmoldassemblydrawingandnon-standardpartsdrawing.Thedesignofmultiplebendingpartsofprogressivediedesignhasacertainunderstanding,laysafoundationforfuturemolddesign.Keywords:pushafixedpiece,progressivedie,diesdesign,structuredesign推件固定片级进模设计及其制造工艺III目录1绪论....................................................................................................................11.1冲压的概念和特点.......................................................................................11.2冲压的设备..................................................................................................21.3冲压技术的现状...........................................................................................31.4冲压技术的发展方向....................................................................................41.5本文主要研究内容.......................................................................................52制件的结构及工艺分析....................................................................................62.1工件的工艺分析...........................................................................................62.2工件方案选择..............................................................................................63模具的工艺计算................................................................................................93.1毛坯展开尺寸计算.......................................................................................93.2排样设计...................................................................................................103.3冲裁力及弯曲力的计算...............................................................................133.4弹簧原件的选用和计算...............................................................................153.5模具的压力中心计算..................................................................................163.6凸凹模刃口尺寸计算..................................................................................174模具主要零部件的结构设计..........................................................................234.1凹模的结构设计.........................................................................................234.2凸模的结构设计.........................................................................................244.3卸料零件的设计.........................................................................................264.4导向方式的选择.........................................................................................274.5垫板、固定板的采用和厚度........................................................................274.6模具的闭合高度的确定...............................................................................274.7辅助零件的设计.........................................................................................284.8上下模座的选用.........................................................................................294.9模柄的选用................................................................................................295冲压设备的选用..............................................................................................306模具材料的选择和加工..................................................................................31推件固定片级进模设计及其制造工艺IV6.1模具材料的选择.........................................................................................316.2模具零件的加工.........................................................................................317模具的装配与调试..........................................................................................367.1模具装配的概述.........................................................................................367.2模具零件的固定方法..................................................................................377.3冷冲模的装配...................
