Laser Quenching: Kev daws teeb meem rau kev kho cua sov ntawm qhov chaw pib
Raws li kev tshaj lij saum npoo hardening technology, laser quenching tau siv dav nyob rau hauv kev kho cua sov ntawm nws lub zog, ua tsaug zog, thiab ib puag ncig kev ua phooj ywg. Nws nrawm nrawm ntawm qhov chaw ua haujlwm uas siv cov nqaj laser thiab ua tiav tus kheej {1} {txias rau lub hardness, thiab nkees ua lub zog ntawm cov khoom siv. Qhov zoo kawg nkaus ua tau raws li qhov yuav tsum tau ua raws li kev lag luam hauv tsheb thiab lub neej ntev ntawm cov thev naus laus zis ntawm kev txhim kho ntawm kev tsim kho tsheb.
I. Cov ntsiab cai tseem ceeb thiab cov yam ntxwv ntawm laser quenching
Cov tub ntxhais ntawm laser quenching lus dag nyob rau hauv kev siv high {{}} rensity lase qhov chaw rau qhov kub me ntsis hauv lub sijhawm luv luv; Tom qab, lub workpiece tso siab rau nws tus kheej thermal conduction rau sai sai txias, ua tiav lub martensic kev hloov pauv kom ua tiav kev ua kom tawv nqaij tawv. Nws cov yam ntxwv tswv yim zoo tshaj yog: nws muaj cov khoom cua kub ceev (ntawm millisecond nplai), uas tuaj yeem txo cov oxidation thiab decarburization ntawm lub workpiece; Nws yuav tsum tsis muaj qhov nruab nrab txias rau txias, ua kom muaj kev phooj ywg ib puag ncig thiab tsis muaj kuab paug; Thiab nws lub zog tau feeb kom tsuas yog ua rau thaj chaw tshwj xeeb, uas ua rau muaj kev sib tw tsawg kawg ntawm qhov chaw ua haujlwm ntawm qhov tseeb.
Ii. Cov tub ntxhais zoo ntawm laser quenching dhau ib txwm quenching
Piv nrog cov txheej txheem ib txwm muaj xws li nplaim taws quenching thiab induction quenching, laser quenching tau tshwj xeeb tshaj yog qhov zoo tshaj plaws. Firstly, nws muaj qhov siab precision- Qhov loj ntawm cov chaw laser thiab txoj kev kuaj pom kev nyuaj, rau cov chaw hauv zos xav tau ntawm qhov chaw nrog cov txheej txheem nyuaj. Thib ob, nws muab kev ua tau zoo tshaj plaws: Lub qhov tob tob tom qab quenching yog ib qho kev ua haujlwm tawv, thiab qhov ua tau zoo txhim kho ntawm cov khoom siv tsis kam thiab cuam tshuam. Thib peb, nws ua tiav qhov sib npaug ntawm kev ua tau zoo thiab tus nqi: nws muaj kev sib xyaw ua ke rau cov txheej txheem txuas ntxiv, thiab txo cov nqi tsim khoom ntau zaus.
III. Cov Kev Siv Cov Ntawv Siv Ntawm Laser Quenching Hauv Cov Txheej Txheem Pib
Laser Quenching tau tau siv dav hauv kev tsim cov khoom siv ntau yam. Hauv lub cav teb, tom qab laser quenching, cov chaw ua haujlwm ntawm crankshafts thiab camshafts tuaj yeem tiv thaiv siab thiab cuam tshuam rau lawv lub neej kev pabcuam. In the transmission system, laser quenching of the tooth surfaces and spline parts of gears and drive shafts can improve wear resistance and fatigue strength, ensuring stable transmission. In chassis components, key load-bearing parts such as steering knuckles and half-shaft sleeves undergo laser quenching to enhance deformation resistance and improve driving safety.
IV. Cov txheej txheem tseem ceeb tswj cov ntsiab lus rau laser quenching ntawm qhov chaw pib
Txhawm rau kom muaj cov nyhuv ntawm laser quenching, nruj tswj kev tswj hwm ntawm cov txheej txheem tseem ceeb yog qhov tsim nyog. Ua ntej, Laser Fais yuav tsum tau hloov kho raws li cov khoom siv ntawm cov seem (piv txwv li steel) thiab cov kev xav tau rau cov khoom tawv tawv, feem ntau li ntawm 1kW mus rau 5kW. Thib ob, kev ntsuas nrawm ncaj qha cuam tshuam rau cov cua kub thiab txias ua tau zoo, yog li nws yog 50 hli dhau los ua rau muaj kev nrawm nrawm dua, thaum muaj kev nrawm nrawm dua tuaj yeem ua rau coinegin loj. Ib qho ntxiv, nws yog ib qho tsim nyog los ntxuav cov roj stains thiab xeb los ntawm cov khoom sib nqus ua ntej kom ntseeg tau tias cov txheej txheem lasercomiency yuav tsum tau siv los txhim kho kev lom zem quenching.
Laser Quenching ua rau cov kev txhim kho ntawm qhov chaw pib kho cua sov
Nrog nws cov ntsiab lus zoo ntawm precision, kev ua phooj ywg, thiab kev hloov pauv ntawm maj mam hloov pauv rau kev kho cua sov ntawm qhov chaw pib. Nws tsis tsuas yog ua tau raws li kev txhim kho kev siv tsheb rau cov ntu tab sis kuj tseem muaj kev pab cuam lub neej ntev li cov chaw ua haujlwm tshiab. Nyob rau hauv lub neej yav tom ntej, nrog kev nruam nruam ntawm laser thev naus laus zis, laser quenching yuav tau thov ntau dav nyob rau hauv Auto- kev loj hlob ntawm kev lag luam automotive.
