Laser Quenching: Cov Lus Qhia Tseem Ceeb rau cov txiaj ntsig zoo, Pretreatment, thiab kev siv
Hauv kev ua teb niaj hnub tsim khoom, kev tsim khoom, thiab txij nkawm, kev xaiv laser quenching rau kev txhim kho cov khoom lag luam zoo vim nws cov txheej txheem kev ua haujlwm tshwj xeeb. Piv nrog tsoosing cov txheej txheem, laser quenching tuaj yeem ua kom muaj kev cuam tshuam zoo, thiab zoo, cov khaub ncaws tsis zoo, cov khaub ncaws tsis sib xws hauv thaj chaw quenched. Nws yog dav siv nyob rau hauv kev tsim khoom thiab kho cov khoom tseem ceeb xws li lub zog thiab cov ntaub qhwv. Kab lus no yuav tshawb txog cov txheej txheem zoo, cov tswv yim ua kom ceev faj, thiab kev xaiv cov txheej txheem ntawm laser kev ua haujlwm rau cov kws ua haujlwm.
Cov txheej txheem tseem ceeb ntawm laser quenching: Tsim nws txoj hauj lwm nyiam hauv kev tsim kho tshuab
Lub luag haujlwm ceev ntawm laser quenching nyob rau hauv cov kev lag luam machinery kev lag luam stems los ntawm nws cov txheej txheem irreplacesable zoo. Firstly Laser Quenching muaj ib qho cua sov heev {}} kev ua haujlwm puas tsuaj rau qhov tsis yog} Qhov no yog qhov tsim nyog rau kev ua cov khoom siv tshuab hluav taws xob. Thib ob, cov khoom ua haujlwm tsis zoo rau qhov tsis txaus ntseeg thaum lub sijhawm quenching, txo lub sijhawm kho kom raug. Thaum kawg, cov nplej hauv thaj chaw quenched tau zoo heev thiab kev hnav khaub ncaws, ncaj qha txhim kho lub neej ua haujlwm los ntawm kev ua haujlwm los ntawm kev ua haujlwm los ntawm kev tswj hwm tus nqi txij nkawm rau cov lag luam.
Cov hom phiaj tseem ceeb ntawm laser quenching pretreatment: ensuring nto zoo thiab ua tau zoo
Pretreplection yog "thawj kab ntawm kev tiv thaiv" rau cov txheej txheem zoo ntawm kev txhim kho qhov chaw zoo thiab kev ua haujlwm tau zoo ntawm lub workpiece. Firstly ua ntej yuav pab tau txais ib qauv hlau uas yog niaj hnub} tsis muaj qhov tsis muaj zog, thiab muaj qhov tsis muaj zog rau kev tsim cov tawv ruaj khov rau tom ntej quenching. Thib ob, nws tsim cov qauv ntom ntom ntom nti, txhim kho lub workpiece tsis kam rau kev sib txhuam thiab hnav cov xwm txheej. Thib peb, nws ua tiav cov khoom sib txawv ntawm cov khoom thaum txhim kho cov kev pheej hmoo ntawm cov khoom ua haujlwm tsis muaj zog thaum ub- kev ua haujlwm. Plaub, nws xyuas kom cov workpiece tswj tau zoo thermal ruaj khov nyob rau hauv high- kub ua hauj lwm tshwm sim los ntawm kev hloov pauv kub.
Cov kev ceeb toom tseem ceeb rau laser quenching pretreatment: preheating thiab kev tiv thaiv kom sov
Hauv cov txheej txheem ua ntej ntawm laser quenching, paub tswj kev tswj hwm ntawm preheating thiab kev tiv thaiv kev tiv thaiv hluav taws xob yog qhov tseem ceeb rau kev ua tsis tiav cov txheej txheem. Vim yog lub zog tseem ceeb heev ntawm lub laser, kev tawm ncaj qha rau kev ua haujlwm cua sov hauv cheeb tsam. Yog li ntawd, preheats txaus yog qhov tseem ceeb-}}} Qhov kev tiv thaiv kub, kom tsis txhob muaj kev tiv thaiv thiab tsis muaj qhov cuam tshuam rau hauv tsis {{3/2 hom phiaj. Ib qho ntxiv, thaum lub caij sov, cov khoom siv hlau yuav tsum tsis txhob txias dua tom qab quenching; Hloov chaw, ib qho 10-20 feeb cua sov thiab cua sov kev kho kom sov. Txoj kev ua haujlwm no tso cai rau cov qauv ua haujlwm ntawm cov qauv ruaj khov ntawm qhov kub thiab qhov kev pheej hmoo ntawm kev ua haujlwm ntawm kev ntxhov siab.
Lub tswv yim xaiv rau Laser Quenching cov txheej txheem: meej phim ntawm cov khoom thiab loj
Kev xaiv ntawm laser quenching cov txheej txheem yuav tsum ua kom haum nrog cov khoom siv thiab loj yuav tsum tau ua kom tiav cov txheej txheem ua haujlwm tau zoo. Los ntawm cov khoom pom zoo, yog tias cov khoom siv yog suav tau ntawm cov ntsiab lus xws li laser quenching los tiv thaiv cov laj kab li cas, uas yuav cuam tshuam rau qhov chaw zoo. Los ntawm qhov loj me me, muaj qhov pom tseeb ntawm qhov loj me, thiab cov khoom txias me me Rau qhov loj-}} qhov loj me uas muaj qhov muaj zog, muaj hluav taws xob muaj zog ua kom tau yooj yim, muaj hluav taws xob muaj zog
Cov Ntsiab Lus Ntawm Laser Quenching Technology: Txhawb cov khoom zoo thiab ua tau zoo hauv kev tsim kho tshuab
Hauv cov ntsiab lus, laser quenching thev naus laus zis, nrog nws cov tswv yim xaiv kom zoo, tau dhau los ua kev txhim kho cov txheej txheem, thiab kev ua haujlwm zoo rau hauv niaj hnub no kev tsim khoom, kev tsim khoom, thiab txij nkawm. Nws tsis tsuas yog txo cov nqi ntawm cov txheej txheem tom ntej los ntawm cov nta me me xws li tseem muaj peev xwm pabcuam lub neej los ntawm kev tshawb fawb lub neej ntawm kev tshawb fawb thiab cov txheej txheem txuam. Rau cov lag luam kev lag luam nrhiav cov khoom siv txhim kho thiab txhim kho cov kev lag luam laser no tuaj yeem ua rau muaj kev sib tw hauv cov tshuab, thiab pwm tsim khoom.
