Dab tsi yog cov txheej txheem rau kev kho cua sov ntawmncaj seam steel yeeb nkab?
Ua ntej ntawm tag nrho cov, layout tsim ntawm technical pwm yuav tsum tsim nyog, lub thickness yuav tsum tsis txhob sib txawv heev, thiab cov duab yuav tsum symmetrical.Rau pwm nrog loj deformation, cov kev cai deformation yuav tsum tau tuav, thiab cov nyiaj machining yuav tsum tau tshwj tseg.Rau cov pwm loj, nplua thiab tsis zoo, cov txheej txheem ua ke tuaj yeem xaiv tau.Rau qee cov pwm zoo thiab tsis zoo, kev kho cua sov ua ntej, kev kho cua sov thaum laus thiab kev tua hluav taws kub thiab tempering nitriding tuaj yeem raug xaiv los tswj qhov tseeb ntawm cov pwm.Thaum kho qhov tsis xws luag xws li xuab zeb qhov, cua qhov thiab hnav cov pwm, kho cov khoom siv nrog thermal cuam tshuam me me xws li lub tshuab vuam txias yuav tsum raug xaiv kom tsis txhob deformation thaum kho.
Cov pwm zoo thiab tsis zoo yuav tsum tau kho ua ntej kom sov kom tshem tawm cov kev ntxhov siab nyob hauv lub sijhawm ua haujlwm.Rau cov pwm zoo thiab tsis zoo, lub tshuab nqus tsev cua sov quenching thiab sib sib zog nqus txias txias tom qab quenching yuav tsum raug xaiv kom deb li deb tau yog tias muaj kev tso cai.Nyob rau hauv lub hauv paus ntawm kev ua kom lub hardness ntawm pwm, ua ntej txias, staged txias quenching los yog sov quenching txheej txheem yuav tsum tau xaiv kom deb li deb li sai tau.
Tsim nyog xaiv cov ntaub ntawv.Rau kev tuag zoo thiab tsis zoo, cov micro deformation tuag steel nrog cov ntaub ntawv zoo yuav tsum raug xaiv.Cov hlau tuag nrog hnyav carbide segregation yuav tsum raug cam khwb cia kom zoo thiab raug quenching thiab tempering kub kho.Rau loj thiab tsis cam khwb cia tuag steel, cov khoom tov ob chav refinement kho cua sov yuav nqa tawm.Tsim nyog xaiv qhov kub thiab txias thiab tswj cov cua kub ceev.Rau cov pwm zoo thiab tsis zoo, cua sov qeeb, preheating thiab lwm yam kev sib npaug ntawm cov cua sov tuaj yeem siv los txo cov pwm kub kho deformation.
JCOE yog cov yeeb nkab ua tshuab rau kev tsim cov kab loj loj tuab phab ntsa steel kav.Nws tsuas yog siv cov txheej txheem ntau lawm ntawm ob sab submerged arc vuam.Cov khoom siv los ntawm ntau yam txheej txheem xws li milling, prebending, dabtsi yog khoov, seam kaw, internal welding, sab nraud vuam, straightening, thiab ca kawg.Cov txheej txheem tsim tuaj yeem muab faib ua N + 1 cov kauj ruam (N yog tus lej zoo).Cov phaj hlau tau txais kev noj qab haus huv thiab khoov raws li cov kauj ruam loj kom paub txog cov lej tswj kev nce qib JCO.Lub phaj hlau nkag mus rau hauv lub tshuab ua kab rov tav, thiab nyob rau hauv lub laub ntawm lub trolley noj, thawj theem ntawm ntau kauj ruam dabtsi yog khoov nrog N / 2 cov kauj ruam yog nqa tawm kom paub qhov "J" tsim ntawm pem hauv ntej ib nrab ntawm cov hlau phaj;Nyob rau theem thib ob, thawj zaug, lub phaj hlau tsim los ntawm "J" yuav tsum raug xa mus rau qhov chaw teev nyob rau hauv txoj kev hloov pauv sai, thiab tom qab ntawd cov phaj hlau tsis muaj hlau yuav tsum tau khoov rau ntau theem ntawm N / 2 los ntawm lwm qhov kawg kom paub. kev tsim ntawm lub thib ob ib nrab ntawm cov hlau phaj thiab ua kom tiav txoj kev "C";Thaum kawg, qhov qis ntawm "C" hom raj dawb yog khoov ib zaug kom paub qhov "O" sib sau.Lub hauv paus ntsiab lus ntawm txhua kauj ruam stamping yog peb-point dabtsi yog khoov.
