雙柱式可傾斜壓力機(jī)的設(shè)計(jì)說明書.doc

I摘要用于對坯料進(jìn)行成型加工的鍛壓機(jī)械稱作壓力機(jī)。機(jī)械壓力機(jī)動(dòng)作平穩(wěn)，工作可靠，廣泛用于沖壓、擠壓、模鍛和粉末冶金等工藝。本次設(shè)計(jì)題目是雙柱式傾斜壓力機(jī)。傾斜式壓力機(jī)由支承著床身和壓頭的底座支架，動(dòng)力電源，壓頭，垂直于床身并作直線運(yùn)動(dòng)的機(jī)構(gòu)組成。傾斜式壓力機(jī)的優(yōu)點(diǎn)是有利于廢料的排出。在設(shè)計(jì)過程中，通過對沖壓功率的分析，確定了飛輪和電動(dòng)機(jī)功率。并且通過計(jì)算確定了各級傳動(dòng)比和基本尺寸。通過計(jì)算確定了系統(tǒng)的最大功率，對帶輪和齒輪機(jī)構(gòu)進(jìn)行了外形尺寸和參數(shù)的計(jì)算。同時(shí)也對曲柄滑塊機(jī)構(gòu)進(jìn)行結(jié)構(gòu)設(shè)計(jì)，根據(jù)計(jì)算解決了曲軸和后軸的尺寸。關(guān)鍵詞：壓力機(jī)；功率；機(jī)構(gòu)IIAbstractThemachineusedformostcold-workingoperationisknownasapress.Itworkssteadyandiswidelyusedinmanyfields,suchasforgingandpressing.Thisdesigntopicistheinclinablepress.Itconsistsofamachineframesupportingabedandaram,asourceofpower,andamechanismtocausetheramtomoveinlinewithandatrightanglestothebed.Inthedesignprocess,bymeansofanalyzingtherammingpower,theflywheelpowerandtheelectricmotorpoweraredetermined；everyleveloftransmissionratiosandtheconstructionsizearealsodeterminedbycomputerprogram.Havingdeterminedthesystemmaximumworkratewithcomputerprogram,ithascarriedontheexternaldimensionsandtheparametercomputationtothebandpulleyandthegearmechanism.Havingcarriedontheintensity,therigidityexaminationtotheslidecrankmechanism,themechanismdesign,themainaxleandthehindaxlesizeandthelocalizationhasbeendeterminedaswell.Keywords:Press；Power；MechanismIII目錄摘要.IAbstract.II第1章緒論.11.1設(shè)計(jì)的目的.11.2設(shè)計(jì)的內(nèi)容.11.3設(shè)計(jì)要求和注意事項(xiàng).11.3.1設(shè)計(jì)要求.11.3.2注意事項(xiàng).21.4傳動(dòng)方案的機(jī)構(gòu)選型原則.21.5傳動(dòng)裝置的方案論證.31.6執(zhí)行機(jī)構(gòu)方案論證.4第2章執(zhí)行機(jī)構(gòu)的設(shè)計(jì)計(jì)算及功率的確定.72.1力、加速度及功率分析.72.2電動(dòng)機(jī)的選擇.9第3章傳動(dòng)機(jī)構(gòu)的設(shè)計(jì)及計(jì)算.123.1帶傳動(dòng)設(shè)計(jì)及計(jì)算.123.1.1確定設(shè)計(jì)功率Pca.123.1.2選擇帶型.123.1.3確定帶輪的基準(zhǔn)直徑dd1和dd2.123.2帶輪的設(shè)計(jì).153.2.1小帶輪的設(shè)計(jì).163.2.2大帶輪的設(shè)計(jì).173.3齒輪的設(shè)計(jì)計(jì)算.183.3.1齒輪的類型、精度等級、材料和齒數(shù).183.3.2按齒面接觸疲勞強(qiáng)度設(shè)計(jì).193.3.3按齒根彎曲疲勞強(qiáng)度的設(shè)計(jì).213.3.4幾何尺寸計(jì)算.233.3.5齒輪的結(jié)構(gòu)設(shè)計(jì).233.4軸的設(shè)計(jì).25IV3.4.1后軸的設(shè)計(jì).253.4.2曲軸的設(shè)計(jì).28第4章軸承、機(jī)座及導(dǎo)軌的設(shè)計(jì).304.1軸承的設(shè)計(jì).304.1.1滾動(dòng)軸承的選擇及校核.304.1.2曲軸兩端滑動(dòng)軸承的設(shè)計(jì).314.2機(jī)座的設(shè)計(jì).334.2.1機(jī)座材料的選擇.334.2.2機(jī)座設(shè)計(jì)的基本要求.334.2.3肋的布置.334.2.4連接結(jié)構(gòu)設(shè)計(jì).334.2.5導(dǎo)軌的功用、分類和應(yīng)滿足的要求.344.2.6直線滑動(dòng)導(dǎo)軌的結(jié)構(gòu)設(shè)計(jì).34結(jié)論.36致謝.37參考文獻(xiàn).38VContentAbstract.IChapter1Introduction.11.1Designpurpose.11.2Designofthecontent.11.3DesignRequirementsandConsiderations.11.3.1DesignRequirements.11.3.2DesignConsiderations.21.4TransmissionSchemeinstitutionalprincipleofselection.21.5Geardemonstrationprogram.31.6Implementingagenciesdemonstrationprogram.4Chapter2Theimplementationofthedesigncalculations.72.1Theanalysisofstrength,accelerationandpower.72.2Thechoiceofthemotor.9Chapter3Designandcalculationoftransmission.123.1Beltdrivedesignandcalculation.123.1.1DeterminethedesignpowerPca.123.1.2Selectthezonetype.123.1.3Determinethereferencediameterofpulleydd1anddd2.123.2Pulleydesign.153.2.1Thedesignofsmallpulley.163.2.2Pulleystructuredesignandselectthezonetype.173.3Designandcalculationsofthegear.183.3.1Thetype,accuracyclass,materialandquantityofgear.183.3.2Toothcontactfatiguedesign.193.3.3Traceofdesignaccordingtoothrootbendingstrength.2
