汽车锁座零件冲压工艺分析及模具设计摘要：模具是现代工业生产中关键工艺装备，本论文关键包含冲压模具工艺设计和弯曲模具工艺设计，整个过程包含工艺方案、工序安排、工序尺寸、使用设备及模具类型，并依据设计出冲裁凸凹模尺寸及技术要求制订其机加工工艺规程，最终绘制出正确冲裁模具装备图和弯曲模具装备图。依据零件技术要求，确定工艺方案为：优异行冲裁然后弯曲。在冲裁工艺阶段，确定两种落料和冲孔方案：一个是落料和冲孔复合；一个是先落料在冲孔。经过各方面计算和比较，确定第一个方案更优。在弯曲阶段，因为孔靠近变形区，弯曲后需要钳工修磨，以达成工艺要求。在凸凹模制造过程中，因为模具制造和通常机械制造相比较，有着特殊技术要求和显著特点，必需区分对待，（1）单件生产：每种模具通常生产1～2副，普遍采取修锉、修配方法加工，工序组合相对集中对工人技术水平要求较高。（2）制造质量高：通常地，模具工作零件制造精度比产品零件高2～4级，需采取坐标磨床、数控机床加工。（3）形状复杂：通常加工难度大，有时需要特种加工或专门化机床。（4）材料硬度高：通常采取工具钢淬火、低温回火，需要采取特种加工方法。关键词：模具冲裁弯曲工艺BlocklockpartsofcarstampingprodessanddiedesignAbstract:Moldisanimportanttechniqueandequipmentinmodernindustrialproduction,Inthispaper,themainprocessinvolvedindesignofstampingdieanddesignofbendingmold,theentireprocessincludingplanningofprocess,organizationofprocess,sizeofprocess,useofequipmentandtypesofmold.Andinaccordancetothesizeofconvexandconcavemoldandtheitstechnicalrequirementscompletethedevelopmentofitsmachiningprocessplanning,eventuallydrawthecorrectassemblingdrawingofblankingdiesandbending.Accordingtothetechnicalrequirementsofparts,Technologyprogramisdeterminedtoblankingfirstlyandthenbending.IntheStageofblankingprocess,Thedevelopmentofblankingandpunchingtwoprograms:oneisthecompositeblankingandpunching;antherisblankfirstlythenpunch.Throughcalculationandcomparisonofvariousaspects,thefirstprogramwastoidentifybetter.IntheStageofbending.Asthedeformationzonebeinnearofthehole,itneedtobendingfitteraftergrindinginordertomeetthetechnicalrequirements.InthemanufacturingprocessofBumpofBlankingDie,moldmanufacturingiscomparedwiththegeneralmachinerymanufacturing,asaresultofitsspecialtechnicalrequirementsanditclearfeatures,woMustbetreateddifferently.(1)One-pieceproduction:Generlly,eachmoldproductfor1～2,Widelyusedprocessingoffilerepair,repairmethods,combinationoftheprocessofrelativeconcentrationanddemandtheworkersofhigherskilllevels;（2）theManufacturingofhigh-quality:Ingeneral,themanufacturingofmoldpartsproductsaremoreprecisionthan2to4highbythegeneralparts,needtotheuseofcoordinategrindingma
