Lub hauv paus ntsiab lus, cov yam ntxwv thiab kev siv tshuab laser quenching
Kev siv laser quenching yog ib qho txheej txheem tshiab uas siv cov teeb laser muaj zog heev los ua kom cov khoom siv kub dhau ntawm lawv cov theem hloov pauv. Thaum cov khoom siv txias, austenite hloov mus ua martensite, tsim ib txheej tawv nrog qhov nyuaj thiab tiv taus kev hnav ntawm cov khoom nto. Cov txheej txheem no hloov pauv cov qauv me me thiab cov khoom ntawm cov khoom ua haujlwm yam tsis muaj kev cuam tshuam rau cov khoom siv hauv paus kev ua tau zoo tag nrho, ua tiav kev txhim kho lub zog hauv zos los ntawm kev tswj hwm thermal ua haujlwm.
Cov yam ntxwv ntawm laser nto quenching muaj xws li:
Lub zog ceev ceev: laser nto quenching siv lub teeb laser tsom mus rau ua qhov chaw cua sov kom sai sai ua kom sov qhov chaw ntawm qhov workpiece thiab tsim austenite.
Kev ua kom sov thiab txias sai: Cov txheej txheem ua tiav kev ua kom sov sai hauv ob peb feeb xwb (feem ntau yog 0.01-0.001 vib nas this), ua kom txo qhov kev hloov pauv ntawm cov khoom ua haujlwm. Txoj kev quenching huv si thiab ua haujlwm tau zoo no tshem tawm qhov xav tau dej lossis roj ua cov neeg sawv cev txias. Piv rau cov txheej txheem induction hardening, nplaim taws hardening, thiab carburizing, laser quenching xa cov txheej txheem hardened sib npaug nrog qhov nyuaj dua (feem ntau yog 1-3HRC siab dua li induction quenching).
Kev Hloov Pauv Tsawg Tshaj Plaws: Cov txheej txheem cua sov thiab txias sai sai txo qhov kev hloov pauv ntawm cov khoom ua haujlwm, tso cai rau kev tswj hwm qhov tob ntawm cua sov thiab txoj kev. Qhov no ua rau automation yam tsis tas yuav tsum muaj cov kauj induction rau ntau qhov loj me, raws li qhov xav tau nrog induction hardening. Nws kuj tshem tawm cov kev txwv qhov loj me ntawm lub cub tawg uas cuam tshuam nrog kev kho cua sov tshuaj xws li carburizing thiab quenching rau cov khoom loj. Yog li ntawd, laser hardening tab tom hloov cov txheej txheem ib txwm muaj xws li induction hardening thiab kev kho cua sov tshuaj thoob plaws ntau yam kev siv hauv kev lag luam. Qhov tseem ceeb, laser hardening ua rau cov khoom siv deformation tsis tseem ceeb ua ntej thiab tom qab kev kho mob. Rau cov khoom siv hlau kub siab uas qhov kub quenching sib xws nrog cov ntsiab lus melting, induction-based surface hardening feem ntau ua rau cov ces kaum lossis thaj chaw tsis xwm yeem, ua rau muaj kev puas tsuaj. Laser surface hardening zam qhov kev txwv no tag nrho.
Yog li ntawd, nws yog qhov tsim nyog rau kev kho qhov chaw ntawm cov khoom uas muaj qhov yuav tsum tau ua kom raug. Cov khoom ua haujlwm kho tsis tas yuav tsum tau sib tsoo thiab tuaj yeem siv ua cov txheej txheem kawg ntawm kev ua tiav.
Haum rau cov duab nyuaj: Siv tau rau cov khoom sib txawv xws li cov qhov dig muag, cov qhov sab hauv, cov qhov me me, cov khoom nyias nyias, thiab lwm yam. Muaj zog ntau yam: Vim yog qhov tob ntawm laser, tsis muaj kev txwv nruj rau qhov loj me, qhov ntev, lossis qhov chaw ntawm cov khoom thaum lub sijhawm quenching. Qhov sib piv, qhov nruab nrab-siab zaus quenching uas twb muaj lawm xav tau cov sensors induction ua tshwj xeeb rau ntau yam khoom;
Qhov tob ntawm cov txheej laser hardened feem ntau nyob hauv 0.3-2.0Mm ntau yam nyob ntawm cov yam xws li cov khoom siv sib xyaw, cov lus qhia tshwj xeeb, cov yam ntxwv ntawm qhov chaw, thiab cov txheej txheem ua haujlwm tseem ceeb. Thaum ua cov kev kho mob quenching ntawm lub caj dab ntawm cov iav loj lossis cov khoom ntawm lub cev muaj zog, qhov roughness ntawm qhov chaw tseem tsis hloov pauv. Qhov no tshem tawm qhov xav tau kev ua haujlwm tom qab ua tiav kom tau raws li cov kev xav tau ua haujlwm tshwj xeeb.
Kev siv laser quenching siv ob txoj kev scanning: kev scanning nqaim nrog cov chaw voj voog lossis plaub fab, thiab kev scanning dav dav siv cov chaw linear. Qhov dav ntawm thaj chaw hardened hauv kev scanning nqaim sib phim nrog lub cheeb tsam ntawm qhov chaw, feem ntau yog nyob hauv 5 hli. Rau cov ntawv thov hardening loj, kev scans sib law liag yog qhov yuav tsum tau ua qhov twg cov cheeb tsam sib tshooj tsim cov kab mos mos. Cov kab no qhov dav nyob ntawm cov yam ntxwv ntawm qhov chaw, nrog rau cov chaw plaub fab sib npaug feem ntau tsim cov kab me dua. Txhawm rau kom txo cov teebmeem tsis zoo ntawm cov kab mos mos, kev siv tshuab scanning dav dav yog siv. Txoj kev no hloov cov chaw voj voog tsom mus rau hauv cov kab linear, nthuav dav qhov dav ntawm kev scanning.
Kev tshawb nrhiav, kev txhim kho, thiab kev siv cov thev naus laus zis laser quenching tam sim no nyob rau theem nce siab, txawm hais tias muaj kev cov nyom hauv kev ua cov khoom ua haujlwm nyuaj. Txawm li cas los xij, ua ib qho kev tsim kho tshiab ntawm kev kho cua sov, laser quenching ua rau ua tiav cov hom phiaj kev siv tshuab uas cov txheej txheem quenching nto ib txwm muaj teeb meem ua tiav. Qhov tseem ceeb, cov txheej txheem no tshem tawm qhov xav tau cov khoom siv txias thaum lub sijhawm tsim khoom, ua raws li kev cog lus thoob ntiaj teb rau "kev tsim khoom qis-oxidation thiab eco-friendly". Nws ua pov thawj tshwj xeeb rau kev kho cua sov ntawm ntau yam khoom siv kho tshuab, suav nrog cov ntug ntawm cov cuab yeej txiav, cov qhov chaw kaw valve, cov iav me me, cov pwm me me, cov khoom siv tsheb, cov nplhaib iav, cov lus qhia ntawm cov cuab yeej siv tshuab, cov ncej tsav tsheb, thiab cov ncej txo qis.
