Crankshafts yog dav siv nyob rau hauv lub cav.Tam sim no, cov khoom siv rau tsheb cav yog cov hlau thiab hlau.Vim tias qhov kev ua tau zoo ntawm cov hlau nplaum, ntau yam kev kho cua sov thiab kev kho kom muaj zog saum npoo yog ua los txhim kho lub zog qaug zog, hardness thiab hnav tsis kam ntawm crankshaft.Ductile hlau crankshafts muaj tus nqi qis, yog li cov hlau crankshafts tau siv dav hauv tsev thiab txawv teb chaws.Hauv qab no peb yuav qhia txog crankshaft manufacturing technology.
Crankshaft manufacturing technology:
1. Casting tshuab ntawm ductile hlau crankshaft
A. Smelting
Kev nrhiav tau ntawm high-temperature, low-sulfur, ntshiab molten hlau yog tus yuam sij rau kev tsim cov hlau zoo.Cov khoom siv hauv tsev yog feem ntau raws li cupola, thiab cov hlau molten tsis yog pre-desulfurized;Qhov thib ob yog high-purity npua hlau thiab coke tsis zoo.Tam sim no, ob-sab sab nrauv pre-desulfurization smelting txoj kev tau txais yuav, uas siv lub cupola yaj molten hlau, desulfurizes sab nraum lub cub tawg, thiab ces heats li thiab kho cov muaj pes tsawg leeg nyob rau hauv ib tug induction rauv.Tam sim no, kev tshawb pom ntawm cov khoom siv hluav taws xob hauv tsev feem ntau tau ua tiav siv lub tshuab nqus tsev nyeem ntawv spectrometer.
B. Qauv
Cov txheej txheem airflow cuam tshuam molding yog pom tseeb zoo dua rau cov av nplaum xuab zeb txheej txheem, thiab high-precision crankshaft castings tuaj yeem tau txais.Cov xuab zeb pwm tsim los ntawm tus txheej txheem muaj cov yam ntxwv ntawm tsis muaj rebound deformation, uas yog tshwj xeeb tshaj yog ib qho tseem ceeb rau lub multi-tig crankshaft.Tam sim no, qee lub tuam txhab crankshaft hauv Suav teb tau tshaj tawm cov txheej txheem airflow cuam tshuam los ntawm lub teb chaws Yelemees, Ltalis, Spain thiab lwm lub tebchaws.Txawm li cas los xij, tsuas yog ob peb lub tuam txhab tau qhia tag nrho cov kab ntau lawm.
2. Forging tshuab ntawm steel crankshaft
Nyob rau hauv xyoo tas los no, ib tug xov tooj ntawm advanced forging cov cuab yeej tau qhia nyob rau hauv Suav teb, tab sis vim muaj tsawg tsawg, ua ke nrog pwm manufacturing technology thiab lwm yam chaw, ib co advanced cov cuab yeej tsis tau ua nws lub luag hauj lwm.Feem ntau, muaj ntau yam khoom qub forging uas yuav tsum tau hloov kho thiab kho tshiab.Nyob rau tib lub sijhawm, rov qab thev naus laus zis thiab cov cuab yeej siv tseem nyob hauv txoj haujlwm tseem ceeb, thiab cov cuab yeej thev naus laus zis tau siv tab sis tseem tsis tau nthuav dav.
3. Mechanical processing technology
Tam sim no, feem ntau cov khoom siv hauv tsev crankshaft yog tsim los ntawm cov cuab yeej siv tshuab zoo tib yam thiab cov cuab yeej siv tshuab tshwj xeeb, thiab cov khoom siv hluav taws xob thiab automation kuj tsawg.Cov cuab yeej siv roughing feem ntau yog siv ntau lub tshuab dhos los tig lub crankshaft lub ntsiab phau ntawv xov xwm thiab lub caj dab, thiab kev ruaj ntseg zoo ntawm cov txheej txheem tsis zoo, thiab nws yog ib qho yooj yim los tsim kom muaj kev ntxhov siab loj, thiab nws yog ib qho nyuaj rau ua tiav qhov tsim nyog.tshuabnyiaj pub.Kev ua tiav dav siv crankshaft sib tsoo tshuab xws li MQ8260 rau kev sib tsoo ntxhib - semi-tiav - zoo sib tsoo - polishing, feem ntau yog los ntawm kev tuav haujlwm, thiab kev ua haujlwm zoo tsis ruaj khov.
4. Kev kho cua sov thiab kev siv tshuab ua kom muaj zog
Cov thev naus laus zis tseem ceeb rau kev kho cua sov ntawm lub crankshaft yog kev kho kom muaj zog saum npoo.Ductile hlau crankshafts feem ntau normalized thiab npaj rau saum npoo.Kev kho qhov chaw ntxiv dag zog feem ntau siv induction hardening lossis nitriding.Forged steel crankshafts yog journaled thiab sib npaug.Cov khoom siv txawv teb muaj xws li AEG tsis siv neeg crankshaft quenching tshuab thiab EMA quenching tshuab.
Wuxi Lead Precision Machinery Co., Ltdmuab cov neeg siv khoom ntawm txhua qhov ntau thiab tsawgkev cai hlau fabrication kev pab cuamnrog cov txheej txheem tshwj xeeb.
