Thaum cov neeg feem coob hnov 'cov khoom siv cam khwb cia hlau', lawv pom qee yam clunky, hnyav, thiab hais ncaj ncees, me ntsis qub. Qhov ntawd yog thawj qhov kev xav tsis zoo. Qhov tseeb yog, nyob rau hauv cov kev siv tshwj xeeb, tsis muaj dab tsi cuam tshuam qhov kev vibration damping thiab hnav tsis kam ntawm ib tug zoo-ua. cam khwb cia hlau iav. Qhov ua kom yuam kev tsis yog nyob rau hauv kev xaiv cam khwb cia hlau, tab sis nyob rau hauv kev paub meej thaum twg thiab yuav siv nws li cas. Kuv tau pom ntau txoj haujlwm ua haujlwm rau hlau lossis hlau hlau tsuas yog vim tus kws ua haujlwm tsis paub txog cov nuances ntawm grey lossis ductile hlau qib rau gearing. Nws tsis yog ib qho khoom siv-haum-tag nrho cov kev daws teeb meem, thiab tau txais nws tsis ncaj ncees lawm txhais tau tias ua tsis tiav ntxov, suab nrov, thiab nqi poob qis.
Kev xaiv khoom tsis yog hais txog lub zog xwb
Wb tham txog qib. Grey hlau, zoo li Chav Kawm 30 lossis 35, muaj qhov zoo tshaj plaws damping peev kuv hais. Nws yog qhov zoo heev rau kev txo cov iav whine hauv cov tshuab loj, qeeb-ceev-xav cov khoom siv mining lossis hnyav conveyors. Tab sis koj tsis tuaj yeem nqa ib daim duab rau lub iav steel thiab ncuav nws hauv grey hlau. Lub zog tensile thiab cuam tshuam tsis kam yog qis dua. Kuv nco qab ib qhov project rau ib daim ntawv zeb lub tshuab ziab khaub ncaws. Qhov pib tsim nyob rau hauv qis-qib grey hlau khaws cia tsim micro-kawg ntawm cov hniav hauv paus tom qab ob peb lub hlis ntawm cyclic loading. Qhov kev ntxhov siab concentration yog tus tua neeg.
Qhov ntawd yog qhov uas cov hlau nplaum (nodular hlau) cov kauj ruam hauv. Cov qib zoo li 65-45-12 lossis 80-55-06 muab kev sib xyaw zoo dua ntawm lub zog thiab damping. Nws coj zoo li hlau tab sis khaws qee qhov zoo ntawm cov hlau cam khwb cia. Peb hloov daim ntawv zeb iav mus rau cov hlau uas muaj ferritic-pearlitic matrix, thiab qhov teeb meem ploj mus. Tus yuam sij tau kho lub vojvoog fillet ntawm tus hniav profile thaum lub sij hawm tsim qauv kom zoo dua cov khoom siv. Qhov no tsis yog CAD liab ua haujlwm; nws yuav tsum tau paub yuav ua li cas cov khoom ntws nyob rau hauv pwm thiab qhov twg shrinkage yuav tsim tsis muaj zog me ntsis.
Tom qab ntawd muaj qhov kev ua si alloying. Ntxiv me ntsis ntawm chromium los yog molybdenum tuaj yeem txhawb kev hnav tsis kam thiab hardness, tab sis nws kuj cuam tshuam rau machinability. Koj tsis tuaj yeem hais qhia ntxiv chrome yam tsis xav txog tag nrho cov txheej txheem saw. Ib tug khub foundry, Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), ib zaug qhia qhov no ntawm ib pawg ntawm cov twj tso kua mis. Lawv ntes tau tias peb cov ntsiab lus alloy uas tau teev tseg yuav tau ua qhov kawg CNC hobbing thiab shaping npau suav phem, hlawv los ntawm cov cuab yeej. Lawv cov lus pom zoo kom tweak qhov sib npaug ntawm alloy thiab kho qhov kev kho cua sov tom qab tau txais kev cawmdim qhov project. Qhov ntawd yog tus nqi ntawm tus neeg muag khoom nrog kev sib sib zog nqus nrhiav thiab kev ua haujlwm hauv qab ib lub ru tsev.
Txoj kev Casting tseem ceeb tshaj qhov koj xav
Xuab zeb casting yog qhov mus-rau ntau, tab sis rau cov hniav iav uas xav tau qhov chaw zoo thiab qhov sib xws ntawm cov pwm, plhaub molding (plhaub pwm casting) feem ntau yog qhov pib ntse dua. Cov xuab zeb resin-bonded muab ib tug ntau smoother nto, uas txhais tau hais tias tsawg Tshuag nyiaj pub rau zaum kawg iav hniav machining. Tsawg machining txhais tau tias koj khaws cov tawv nqaij cam khwb cia, uas feem ntau yog qhov nyuaj tshaj plaws thiab feem ntau hnav-resistant txheej.
Kuv tau ua yuam kev thaum ntxov, kho cov casting tsuas yog ib qho ntxhib. Peb machined tseg tag nrho cov hniav profile los ntawm cov xuab zeb-cam khwb cia rau ib tug loj idler iav. Qhov tshwm sim? Nws hnav tsis sib xws. Lub re-machined nto tsis muaj tib lub porosity los yog graphite qauv raws li cov cam khwb cia nto.

Qhov no yog qhov uas lub tuam txhab txoj kev sib koom ua ke, zoo li QSY qhov tshwj xeeb hauv ob qho tib si plhaub molding thiab CNC machining, qhia nws muaj nqis. Lawv npaj cov machining datums thiab nyiaj pab nyob rau hauv tandem nrog lub pwm tsim.
Rau qhov nyuaj heev lossis me me precision zog, peev casting tuaj yeem yog qhov kev xaiv, tab sis nrog cam khwb cia hlau, nws tsis tshua muaj vim qhov kub thiab txias. Nws yog ntau tshaj rau lawv cov tshwj xeeb alloy iav. Lub ntsiab lus yog, kev xaiv ntawm xuab zeb, plhaub, thiab txawm tias centrifugal casting cuam tshuam cov qauv nplej, suab nrov, thiab thaum kawg, lub iav qhov kev ua tau zoo nyob rau hauv load. Koj yuav tsum phim txoj kev rau lub iav qhov loj, kom muaj nuj nqis, thiab qib zoo.
Machining: Qhov twg Theoretical ntsib qhov tiag
Qhov no yog qhov kev npau suav ntawm geometry zoo meej ntaus qhov tseeb ntawm cov cuab yeej sib tham. Cam khwb cia hlau yog nkig. Machining iav hniav, tshwj xeeb tshaj yog hobbing los yog shaping, yuav tsum tau nruj setups thiab tshwj xeeb cov cuab yeej geometries kom tsis txhob fracturing ntawm cov npoo. Coolant (los yog tsis muaj) yog ib qho kev sib cav loj heev. Qee qhov kev cog lus los ntawm kev siv tshuab ziab khaub ncaws nrog coated carbides kom tsis txhob muaj cua sov thiab cov plua plav hlau sib xyaw nrog cov dej txias. Lwm tus siv lub siab txias txias kom tshem tawm cov chips thiab tswj cov cua sov.
Kuv lean ntawm qhuav los yog MQL (tsawg kawg kom muaj nuj nqis lubrication) rau feem ntau cam khwb cia hlau iav qhov chaw tom qab muaj kev tsis zoo nrog lub qhov dej txias. Peb muaj batch ntawm ductile hlau iav rau kev ua liaj ua teb gearbox. Tom qab machining, residual coolant pooled nyob rau hauv lub ntsia liaj qhov rooj qhov thiab roj galleries.
