第1頁1700冷軋機(jī)組卷取機(jī)設(shè)計(jì)摘要卷取機(jī)是軋鋼成卷生產(chǎn)不可少的設(shè)備。保證卷取機(jī)順利工作對(duì)提高軋機(jī)生產(chǎn)率有很重要意義。冷軋機(jī)組中，卷取機(jī)用于卷取帶鋼成鋼卷。采用恒張力軋制，可以提高帶鋼質(zhì)量。這次設(shè)計(jì)是1700冷軋機(jī)組卷取機(jī)設(shè)計(jì)，其用于二機(jī)架冷軋機(jī)組中。首先，選擇卷取機(jī)的設(shè)計(jì)方案，并對(duì)設(shè)計(jì)方案進(jìn)行評(píng)述。由于冷帶鋼卷取張力大，采用四棱錐卷筒結(jié)構(gòu)。用液壓缸移動(dòng)斜楔進(jìn)行脹縮。將四棱錐體單獨(dú)加工裝在卷筒軸上，這樣改進(jìn)，加工方便。當(dāng)錐體磨損后可以單獨(dú)更換。這樣，可以降低設(shè)備維修費(fèi)用。另外，四個(gè)扇形塊邊采用搭接技術(shù)，防止卷筒脹開后出現(xiàn)空隙，減少鋼卷局部壓扁，提高鋼卷質(zhì)量。去掉鉗口，采用助卷器卡緊帶鋼頭部，方便卸卷。這次設(shè)計(jì)，進(jìn)行主電機(jī)容量的計(jì)算和選擇。對(duì)斜楔進(jìn)行受力分析。計(jì)算帶鋼卷取過程中對(duì)卷筒的壓力并計(jì)算卷取軸彎曲強(qiáng)度，對(duì)傳動(dòng)齒輪進(jìn)行設(shè)計(jì)計(jì)算。對(duì)支承軸承進(jìn)行選擇和校核。采用合理的潤(rùn)滑方案、潤(rùn)滑方法和控制技術(shù)，使卷取機(jī)技術(shù)先進(jìn)，經(jīng)濟(jì)合理。強(qiáng)度足夠，有廣泛的使用價(jià)值，可用于酸洗、熱處理、鍍鋅和鍍鋅機(jī)組中。關(guān)鍵詞：卷取機(jī)，斜楔脹縮，助卷第2頁1700coldrollingunitcoilerdesignAbstractThecoilerisrollssteelthevolumeproductionnottobepossiblethefewequipment.Guaranteedthecoilersmoothworktoenhancestherollingmillproductivitytohavetheveryvitalsignificance.Inthecoldrollingunit,thecoilerusesinthevolumetakinghoopChengGangjuan.Usesthepermanenttensityrolling,mayimprovethehoopquality.Thelapmachinedesignof1700coldcalendarunitstousedfortwoexpansionsofcoldcalendarunits.Firstofall,choicethedesignprojectoflapmachine,andcarryonacommenttowardsit.Inthatthecoldstripsoflaptensileforceisbig,adoptfourribawlsrollstructures.Usingthehydrauliccylindertomovetheobliquewedgetoexpansionandcontracting.Itisconveniencethatprocessingfourribawlsaloneandsettingontheroll.Whentheawlswearaway,wecanreplaceitalone.Soitwillreducethemaintenancecostsofequipments.Inaddition,fourfan-shapedpiecesideadoptionstakingthelaplayinglapworktechniqueforavoidingappearingintersticeafterrollingexpansion,reducingthesteelrollpartstostavingandenhancingqualityofstrips.Tothrowawaythepliers,takingauxiliaryrollmachinetotakethestripstightlyforunloadsstripsconveniently.Thedesignoftaskisthatcalculationandchoiceofthemainelectricalengineeringcapacity.Toanalyzeforceoftheobliquewedge.Thecalculationthattherollstressoftakingstripsandflectionintensityoftherollshaft,andtransmissiongears.Choiceandcheckingbearings.Takingreasonableprojectandmethodoflubricating,andcontroltechnique,inordertothelapmachinehasadvancedtechnique,reasonableeconomy,theintensityisenoughandextensiveusingvalue.Itcanbeusedforsourwash,hotprocessing,galvanizationandgalvanizationunits.Keyword:lapmachine,theobliquewedgeexpansionandcontracting,auxiliaryroll第3頁目錄1緒論11.1選題的背景和目的11.2帶鋼卷取機(jī)國(guó)內(nèi)外發(fā)展11.3冷帶鋼卷取機(jī)研究?jī)?nèi)容和方法21.3.1冷軋機(jī)組平面布置圖，卷取機(jī)的作用21.3.2冷帶鋼卷取機(jī)的類型和特點(diǎn)31.3.3帶鋼卷取機(jī)研究?jī)?nèi)容和方法32方案的選擇與分析53卷筒的設(shè)計(jì)計(jì)算63.1卷筒當(dāng)量半徑的確定63.2卷筒徑向壓力的計(jì)算63.3卷筒的強(qiáng)度條件83.4卷取張力的計(jì)算83.5卷筒脹縮機(jī)構(gòu)受力分析83.5.1卷取工作時(shí)收縮時(shí)的受力分析93.5.2卸卷時(shí)卷筒縮徑的受力分析113.6軸向脹縮液壓缸行程計(jì)算113.7脹縮缸直徑的計(jì)算134卷筒傳動(dòng)設(shè)計(jì)144.1電機(jī)的額定轉(zhuǎn)速與傳動(dòng)比144.2激磁調(diào)整范圍與最大卷徑比144.3卷筒電機(jī)功率計(jì)算155減速器的設(shè)計(jì)計(jì)算175.1傳動(dòng)裝置的運(yùn)動(dòng)和動(dòng)力參數(shù)175.2齒輪的設(shè)計(jì)計(jì)算175.2.1選定齒輪類型、精度等級(jí)、材料及齒數(shù)175.2.2按齒面接觸強(qiáng)度設(shè)計(jì)175.3心軸的校核235.3.1作出心軸的計(jì)算簡(jiǎn)圖235.4軸的計(jì)算簡(jiǎn)圖285.4.1作出軸的計(jì)算簡(jiǎn)圖286軸承計(jì)算326.1軸承的壽命計(jì)算3
