No摘要冲压模具在实际工业生产中应用广泛。随着当今科技的发展，模具已经越来越多地被应用到工业生产中来。冲压模具可以大大的提高劳动生产效率，减轻工人负担，具有重要的技术进步意义和经济价值。冲压工艺是一种生产效率很高的、少切屑或无切屑的先进加工方法，在经济和技术方面都有很多的优点。冲压工艺按其变形性质可以分为材料的分离和成形两大类，每一类中包括许多不同的工序.本次设计的零件为轮盘冲压，所用材料是Q235。本论文分析了该工件的成形工艺，计算了该工件的毛坯形状尺寸及各工序尺寸，并在此基础上确定了合理的冲压工序，分为三道工序分别为工序一落料和拉深，工序二冲孔腰形孔，工序三内外缘翻边。此方案的特点是模具结构简单，制造成本低，操作方便，并且尺寸和精度达到工艺要求，具有良好的性价比。本设计工序采用曲柄压力机进行冲压，具有生产效率高、维修简单、工作环境整洁等特点。本文模具进行模具结构的分析，主要零件的设计和模具的经济分析，并且详细介绍了设计方法和步骤。关键词：冲压工艺；模具设计；曲柄压力机；复合模AbstractPunchingdieswasusedwidelyinindustrialproductionapplications.Withtoday'stechnologydevelopment,moldhasbeenanincreasinguseofindustrialproduction.Punchingdiecangreatlyimprovelaborproductivityandreducetheburdenoftheworkers,furthermoreithasimportanttechnologicalprogressandeconomicvalue.Punchingprocessisahighproductionefficiency,noorlessprocessmethods,intheeconomicandtechnicalaspectswhichhasmanyadvantages.TheessentialprocedureofPunchingareseparatingandshaping,eachcategoryincludesanumberofdifferentprocesses.Thisdesigncomponentsiswheelplate,thematerialofwheelplateisQ235.Inthepaper,themoldingtechnologyofthestainlesssteeldrawingpartwasanalyzed,thedimensionsandshapeoftheblankwerecalculated,thedrawingtimesanddimensionsofthepartweredeterminedandmadesureonthisfoundationreasonableofhurtleandpresstheworkprefaceisdividedintothreeworkingproceduredifferenceasthefirstworkingprocedureisblankandelongating,thesecondworkingprocedureistheworkprefacefourslicethesideandpressingtheraisedpackage,thethirdworkingprocedureispiercing.Thecharacteristicsofthisprojectisthemoldingtoolstructuresimple,themanufacturingcostislow,operationconvenience,andthesizeandaccuraciesattainthecraftrequest,havingthelowpriceandwellqualitytocompare.Thedesignprocedureadoptsthecrankpressuremachinetopresstheparts.Becauseithasmanymerits,suchasproducingefficiencyhigh,maintainingsimpleandworksurroundingneatness.Inthispaper,analyzesthecombinationdiecraftsrespectivelyandgivesadetailedintroductiontothecalculationmethodandsteps.Keywords:Punching；moldstructure；crank；
