PAGE\*MERGEFORMAT25摘要本次设计的题目是工艺花瓶的冲模设计,体现了冲压零件的设计要求、内容及设计方向,是一次很有意义的设计.在本次设计中主要针对级进模进行设计。首先对冲裁件进行了结构分析,依次确定模具的类型、结构,接着确定模具的冲裁力和相关尺寸参数的计算,以及标准件的选用,最后运用AutoCAD软件进行零件图和装配图的绘制。本次模具设计并不复杂主要采用理论与实践相结合的方式，运用所学理论知识，以及几次课程设计的经验，基于CAD软件作图以及所学的模具知识，再阅读大量相关文献资料，教材及新闻背景资料，在辅导老师的指导和帮助下完成本次毕业设计。冲压件是靠压力机和模具对板材、带材、管材和型材等施加外力,使之产生塑性变形或分离,从而获得所需形状和尺寸的工件(冲压件)的成形加工方法。实践证明，模具的设计光靠理论知识远远不够，还要有实际的经验才能设计出更合理的模具。所以我在此写下此论文。关键字：工艺花瓶;级进模;AutoCAD软件AbstractThetopicofthisdesignisthepunchingdiedesigncraftvase,embodiesthedesignrequirementsofstampingparts,contentanddesigndirection,isaverymeaningfuldesign.Inthisdesignisaimedatprogressivediedesign.Firsthedgecuttingstructureanalyses,inturndeterminethetype,structureofthemould,thendeterminethemouldsizeparametersofthecuttingforceandtherelatedcalculation,andthechoiceofstandardparts,byusingthesoftwareofAutoCADdrawingpartsdrawingandassemblydrawing.Thedesignofthemouldisnotcomplexmainlyadoptsthewayofcombiningtheoryandpracticeoflearningtheoryknowledge,experienceandafewcoursedesign,drawingandlearnedknowledgeofmoldbasedonCADsoftware,andthenreadalargenumberofrelevantliterature,teachingmaterialandnewsbackground,undertheguidanceoftutorandhelptocompletethegraduationdesign.Stampingistheuseofinstalledinstampingdevice(press)onthemoldtoputpressureonthematerialtoproduceaseparationorplasticdeformation,aprocessingmethodtoobtaintherequiredparts.Practiceprovedthatmoulddesigntheoryknowledgealoneisnotenough,musthavethepracticalexperiencetodesignamorereasonablemould.SoIamwritingthisthesis.Keywords:progressivedieprocessvaseAutoCADsoftware目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc403311159"引言PAGEREF_Toc403311159\h1HYPERLINK\l"_Toc403311160"第一章工艺花瓶的工艺设计PAGEREF_Toc403311160\h3HYPERLINK\l"_Toc403311161"1.1工艺花瓶的轴测图及三视图PAGEREF_Toc403311161\h3HYPERLINK\l"_Toc403311162"1.2工艺花瓶的工艺分析PAGEREF_Toc403311162\h4HYPERLINK\l"_Toc403311163"1.3工艺花瓶的工艺方案选择PAGEREF_Toc403311163\h4HYPERLINK\l"_Toc403311164"1.4凸、凹模刃口尺寸计算PAGE
