I摘要用于对坯料进行成型加工的锻压机械称作压力机。机械压力机动作平稳，工作可靠，广泛用于冲压、挤压、模锻和粉末冶金等工艺。本次设计题目是双柱式倾斜压力机。倾斜式压力机由支承着床身和压头的底座支架，动力电源，压头，垂直于床身并作直线运动的机构组成。倾斜式压力机的优点是有利于废料的排出。在设计过程中，通过对冲压功率的分析，确定了飞轮和电动机功率。并且通过计算确定了各级传动比和基本尺寸。通过计算确定了系统的最大功率，对带轮和齿轮机构进行了外形尺寸和参数的计算。同时也对曲柄滑块机构进行结构设计，根据计算解决了曲轴和后轴的尺寸。关键词压力机；功率；机构IIABSTRACTTHEMACHINEUSEDFORMOSTCOLDWORKINGOPERATIONISKNOWNASAPRESSITWORKSSTEADYANDISWIDELYUSEDINMANYFIELDS,SUCHASFORGINGANDPRESSINGTHISDESIGNTOPICISTHEINCLINABLEPRESSITCONSISTSOFAMACHINEFRAMESUPPORTINGABEDANDARAM,ASOURCEOFPOWER,ANDAMECHANISMTOCAUSETHERAMTOMOVEINLINEWITHANDATRIGHTANGLESTOTHEBEDINTHEDESIGNPROCESS,BYMEANSOFANALYZINGTHERAMMINGPOWER,THEFLYWHEELPOWERANDTHEELECTRICMOTORPOWERAREDETERMINED；EVERYLEVELOFTRANSMISSIONRATIOSANDTHECONSTRUCTIONSIZEAREALSODETERMINEDBYCOMPUTERPROGRAMHAVINGDETERMINEDTHESYSTEMMAXIMUMWORKRATEWITHCOMPUTERPROGRAM,ITHASCARRIEDONTHEEXTERNALDIMENSIONSANDTHEPARAMETERCOMPUTATIONTOTHEBANDPULLEYANDTHEGEARMECHANISMHAVINGCARRIEDONTHEINTENSITY,THERIGIDITYEXAMINATIONTOTHESLIDECRANKMECHANISM,THEMECHANISMDESIGN,THEMAINAXLEANDTHEHINDAXLESIZEANDTHELOCALIZATIONHASBEENDETERMINEDASWELLKEYWORDSPRESS；POWER；MECHANISMIII目录摘要IABSTRACTII第1章绪论111设计的目的112设计的内容113设计要求和注意事项1131设计要求1132注意事项214传动方案的机构选型原则215传动装置的方案论证316执行机构方案论证4第2章执行机构的设计计算及功率的确定721力、加速度及功率分析722电动机的选择9第3章传动机构的设计及计算1231带传动设计及计算12311确定设计功率PCA12312选择带型12313确定带轮的基准直径DD1和DD21232带轮的设计15321小带轮的设计16322大带轮的设计1733齿轮的设计计算18331齿轮的类型、精度等级、材料和齿数18332按齿面接触疲劳强度设计19333按齿根弯曲疲劳强度的设计21334几何尺寸计算23335齿轮的结构设计2334轴的设计25IV341后轴的设计25342曲轴的设计28第4章轴承、机座及导轨的设计3041轴承的设计30411滚动轴承的选择及校核30412曲轴两端滑动轴承的设计3142机座的设计33421机座材料的选择33422机座设计的基本要求33423肋的布置33424连接结构设计33425导轨的功用、分类和应满足的要求34426直线滑动导轨的结构设计34结论36致谢37参考文献38VCONTENTABSTRACTICHAPTER1INTRODUCTION111DESIGNPURPOSE112DESIGNOFTHECONTENT113DESIGNREQUIREMENTSANDCONSIDERATIONS1131DESIGNREQUIREMENTS1132DESIGNCONSIDERATIONS214TRANSMISSIONSCHEMEINSTITUTIONALPRINCIPLEOFSELECTION215GEARDEMONSTRATIONPROGRAM316IMPLEMENTINGAGENCIESDEMONSTRATIONPROGRAM4CHAPTER2THEIMPLEMENTATIONOFTHEDESIGNCALCULATIONS721THEANALYSISOFSTRENGTH,ACCELERATIONANDPOWER722THECHOICEOFTHEMOTOR9CHAPTER3DESIGNANDCALCULATIONOFTRANSMISSION1231BELTDRIVEDESIGNANDCALCULATION12311DETERMINETHEDESIGNPOWERPCA12312SELECTTHEZONETYPE12313DETERMINETHEREFERENCEDIAMETEROFPULLEYDD1ANDDD21232PULLEYDESIGN15321THEDESIGNOFSMALLPULLEY16322PULLEYSTRUCTUREDESIGNANDSELECTTHEZONETYPE1733DESIGNANDCALCULATIONSOFTHEGEAR18331THETYPE,ACCURACYCLASS,MATERIALANDQUANTITYOFGEAR18332TOOTHCONTACTFATIGUEDESIGN19333TRACEOFDESIGNACCORDINGTOOTHROOTBENDINGSTRENGTH21334GEOMETRICSIZEDIMENSIONS23335GEARSTRUCTURALDESIGN2334DESIGNOFTHESHAFT25341DESIGNOFTHEBEHINDAXLE25342DESIGNOFTHEBENTAXLE28
