洛阳理工学院毕业设计（论文）铰链冲压工艺分析及模具设计摘要模具作为高效率的生产工具的一种，是工业生产中非常重要的工艺装备。随着我国工业和高科技产业的快速发展，冲压模具的设计与制造变得越来越重要。根据设计铰链的尺寸、材料等要求，首先分析铰链的工艺性，确定冲裁工艺方案及模具结构方案，即该铰链需要落料-冲孔复合模和弯曲模完成。然后通过工艺设计计算，确定排样方式。计算冲裁力和压力中心，初选压力机，计算刃口尺寸和公差，最后设计和选用零部件。其中在结构设计中，主要对凸模、凹模、凸凹模、定位零件、卸料与顶件装置、冲压设备、模架、紧固件等进行了设计或选择。绘制模具总装图及零件图，最终完成模具设计。关键词：铰链，模具设计，落料-冲孔，复合模I洛阳理工学院毕业设计（论文）HINGESTAMPINGPROCESSANALYSISANDMOULDDESIGNABSTRACAsakindofefficientproductiontool,mouldisaveryimportantcraftequipmentinindustrialproduction.Withtherapiddevelopmentofourcountryindustryandhigh-techindustry,stampingmoulddesignandmanufacturingbecomesmoreandmoreimportant.Accordingtothesize,materialsoftheproduct,thefirstpartistoanalysistheprocessofthehinge,sotheprogramofblankingprocessandmouldstructurehasbeenconfirmed.Asaresult,blanking-punchingcompoundmouldandbendingmouldareusedtoproducethehinge.Thenbasedontheprocessdesigncalculations,thestocklayoutdesigncanbeensured.Itisneededtocarryontheblankingforceandthecenterofpressurecomputation,accordingtowhichthepresscanbeselected.Calculatingthecuttingedgesizeandtolerance,thendesignandchoosethepartsofmould.Duringthestructuredesign,itismainlyaboutthedesignofthepunch,die,punchanddie,positioningparts,unloadingandejectingdevices,mold,pressingequipment,fastenersandsoon.Thendrawthedrawingsandassemblydrawingsofparts,finallythedesignhasbeencompleted.KEYWORDS:Hinge，moulddesign，blanking-punching，compounddieII洛阳理工学院毕业设计（论文）目录前言..................................................................................................1第1章加工零件的工艺分析....................................21.1零件分析........................................................................21.1.1零件简图..............................................................21.1.2冲压件的工艺分析....................................21.1.3分析比较和确定工艺方案.................2第2章落料冲孔复合模.................................................42.1工件展开图的尺寸计算.................................42.2冲压模具工艺与设计计算..........................52.2.1排样设计..............................................................52.2.2排样计算..............................................................62.3确定模具压力中心..............................................62.4工作力的计算...........................................................82.5计算凸、凹模刃口尺寸.................................92.5.1落料部分凸凹模尺寸计算.................92.5.2冲孔部分凸凹模尺寸计算.............11第3章模具结构设计....................................................123.1落料冲孔复合模结构形式....................123.2落料凹模的结构设计....................................123.3冲孔凸模的结构设计....................................133.4凸凹模的结构设计...........................................143.5定位装置的选择.................................................153.6顶件及卸料装置的选择..............................153.7模架的选择..............................................................173.8模柄选择......................................
