客车水槽铝型材挤压模具设计摘要本设计开始就对客车水槽做了结构工艺分析，综合考虑采用卧式挤压机进行热正挤压的成型方式，并进一步分析了6063铝合金的各项性能，确定了生产过程的各个详细的工艺参数及生产流程。紧接着选择了500吨的挤压设备，选用4Cr5MoSiV1作为模具材料，并确定使用平面模来对产品进行生产，确定平面模的外形尺寸、采用预应力组合凹模、模孔数为2、模孔为中心对称分布、模孔外形尺寸的修正及模孔工作带长度并对平面模进行了强度校核；考虑添加了模孔形状为椭圆形的导流模，计算了锭坯尺寸、挤压比和挤压力。最后对挤压工具进行了设计，主要涉及挤压筒的设计，其中挤压筒采用内外两层的结构形式；选择内外套的配合形式及各项尺寸，并进行强度校核；挤压轴的设计，主要有挤压轴的结构形式及具体尺寸，并校核；挤压垫片设计，主要有尺寸选取及强度校核。本套模具投入使用时，可在490℃-530℃的温度下生产出表面粗糙度可达到0.4的客车水槽，最高挤压速度可达80m/min。关键字：铝型材，挤压，模具设计，制造BussinksaluminumprofileextrusiondiedesignABSTRACTThedesignofspacetodothetechnologyanalysisofstructuresink,comprehensiveconsiderationoftheextrusionmachineadoptshorizontalheatisextrusionmoldingway,andfurtheranalyzesthevariouspropertiesof6063aluminumalloy,determinetheproductionprocessofeachdetailedprocessparametersandtheproductionprocess.Andthenchoosethe500tonsofextrusionequipment,use4Cr5MoSiV1asmouldmaterial,andmakesuretouseplanemodetotheproductproduction,todeterminethesize,shapemodelplaneusingprestressedconcretecombinationconcavedie,dieholefor2,modelholeforthesymmetricdistributioncenter,modelholeshapedimensionoffixedandmodelholewithlengthoftheplaneandworkstrengthcheckmodule;Consideraddedmodelholeshapefortheovaldiversionmodule,andcalculatedthepiecesofbilletsize,extrusionratioandtheimpactextrusion.Finallythedesignofextrusiontool,mainlyrelatingtothedesignofthetubeextrusion,includingextrusionwithtwolayersinsideandoutsideofthetubestructureform;Choiceofinternalandexternalsetwithformsandthesizeandintensity;Squeezeoftheaxisdesign,aremainlyjostlingoftheaxisstructureformandthedetaileddimension,andchecked;Dummyblocksdesign,basicallyhavesizeselectionandintensity.Thesetofthemouldputintouse,canbein490to530temperatureoutput℃℃growsinthesurfaceroughnessof0.4bussinks,highestextrusionspeedcanreach80m/min.KEYWORDS：AluminumalloyProfile,extrudingmold,design,manufacture目录前言.........................................................................................................................1第一章结构工艺分析..........................................................21.1产品工艺分析...................................................................21.1.1产品结构分析..........................................................21.1.2挤压方式的分析确定............................21.1.3挤压模具的初步选定............................31.26063铝合金工艺分析................................................31.2.16063铝合金的应用................................................31.2.26063铝合金的特点................................................41.2.36063铝合金的组成................................................41.2.46063铝合金的性能................................................41.3挤压工艺流程及工艺参数...................51.3.1挤压工艺流程..........................................................51.3.2挤压工艺及工艺参数条件的确定...............................................................................................................5第二章平面模设计...
