内容简介：

有凸缘圆筒形件冲压成形工艺及模具设计摘要本论文介绍了拉深的成形方法和条件，拉深是利用拉深模在压力机的压力作用下，将平板坯料或空心工序件制成开口空心件的加工方法。旋转体拉深时的应力应变分析，还有拉深过程中的起皱和拉裂。拉深件毛坯的尺寸计算，和工艺计算，以及拉深次数的计算。拉深模结构相对较简单。根据拉深模使用的压力机类型不同，拉深模可分为单动压力机用拉深模和双动压力机拉深模；根据拉深顺序分为首次拉深和以后各次拉深；根据工序组合可分为单工序拉深、复合工序拉深和连续工序拉深；根据压料情况可分为有压边装置和无压边装置拉深。从模具设计到零部件的加工工艺以及装配工艺等进行详细的阐述，并应用CAD进行各重要零件的设计关键词工艺分析拉深成型模具装配模具结构THESTAMPINGPROCESSANDDIEDESIGNOFTHECYLINDRICALPIECESOFAFLANGEABSTRACTTHEPAPERINTRODUCEDTOPULLTOTAKESHAPEMETHODANDCONDITIONDEEPLY,PULLINGISTHEPRESSUREFUNCTIONTHATTHEEXPLOITATIONPULLSADEEPMOLDINTHEPRESSUREMACHINEDEEPLYUNDER,ANTICIPATEFLATPANELORTHEHOLLOWWORKPREFACEPIECEMAKEINTOOPENMOUTHAHOLLOWPIECETOPROCESSAMETHODREVOLVINGTHEBODYPULLSDEEPHOUROFSHOULDDINTCONTINGENCYANALYSIS,ALSOHAVEALREADYPULLEDDEEPPROCESSINOFSHRIVELANDPULLCRACKPULLADEEPPIECETHESIZECALCULATIONOFTHESEMIFINISHEDPRODUCT,ANDTHECRAFTCOMPUTE,ANDPULLTHECALCULATIONOFDEEPNUMBEROFTIMESPULLDEEPMOLDSTRUCTUREOPPOSITEMORESIMPLEACCORDINGTOPULLTHEPRESSUREMACHINETYPEDISSIMILARITYTHATTHEDEEPMOLDUSES,PULLINGTHEDEEPMOLDCANISDIVIDEDINTOALISTTOMOVEPRESSUREMACHINETOUSETOPULLDEEPMOLDANDDOUBLETOMOVEPRESSUREMACHINETOPULLADEEPMOLDACCORDINGTOPULLDEEPLYINPROPERORDERISDIVIDEDINTOFORTHEVERYFIRSTTIMEPULLDEEPLYWITHLATEREACHONEPULLDEEPLYACCORDINGTOTHEWORKPREFACECOMBINATIONCANISDIVIDEDINTOASINGLEWORKPREFACETOPULLDEEPLY,COMPOUNDTHEWORKPREFACEPULLTODEEPLYPULLWITHCONTINUOUSWORKPREFACEDEEPLYACCORDINGTOPRESSINGTOANTICIPATEACIRCUMSTANCECANISDIVIDEDINTOPRESSSIDEDEVICEANDDONTPRESSSIDEDEVICETOPULLDEEPLYDESIGNTOZEROPARTSESTOPROCESSACRAFTANDASSEMBLECRAFTSETCTOCARRYONTOELABORATEINDETAILFROMTHEMOLDINGTOOL,ANDTHEDESIGNAPPLIEDCADTOCARRYONEACHIMPORTANTSPAREPART
