Laser Quenching thiab kho ntawm cov zog loj: Cov txheej txheem kev tsom xam thiab daim ntawv thov tus nqi
Loj zog loj tshaj tawm cov khoom sib txawv xws li cov cuab yeej hnyav xws li cua lub hwj chim, tsuas, thiab nws yog xim hlau machinery. Lawv ris cov khoom hnyav, cuam tshuam, thiab hnav dhau lub sijhawm ntev, xav tau cov kev pabcuam siab thiab ntev kev pabcuam lub neej. Tsoos kev cais cov txheej txheem (piv txwv li, induction quenching, nplaim taws quenching) feem ntau ua rau thermal deformation thiab txo qhov txiaj ntsig ntawm cov lus tawm loj; Kev kho cov qauv ib txwm (piv txwv li, surfacing vuam) kuj tsis tau raws li siab - precision cov kev xav tau. Txawm li cas los xij, kev sib xyaw ua ke ntawm laser quenching thiab laser cladding technologies ", tau dhau los ua cov ntsiab lus tseem ceeb, tau dhau los ua cov ntsiab lus mob hauv kev ua thiab kho cov zog loj. Kab lus no yuav piav ntau ntxiv ntawm cov txheej txheem tseem ceeb thiab cov ntawv thov tus nqi ntawm cov thev naus laus zis no.
Core Qhov Zoo: Tsawg puas tsuaj, siab precision, thiab kev kho kom zoo nkauj kho tau
Piv nrog cov txheej txheem tsoos, qhov zoo ntawm laser quenching thiab kho cov thev naus laus zis ua kom pom tseeb ntawm peb qhov ntev. Ua ntej, cov lus qhia tshav kub yog me me: Lub zog siv laser yog cov txheej txheem sib txawv ntawm cov iav thiab tswj hwm nws cov qauv qub (piv txwv li 1328 tus qauv qib 6-7 precision). Thib ob, cov hniav nto zoo nyob: tom qab ua, roughness ntawm tus hniav nto yog tseem tswj hwm qhov kev xav tau ntawm iav sib tsoo thiab txo tus txheej txheem nqi. Thib peb, kev kho cov khoom siv yog muaj zog: laser cladding yuav ncaj qha rau cov hniav tawg ncaj qha, nrog rau tus nqi tawg, nrog rau tus nqi tawg, nrog rau cov nqi hloov tshiab, txo cov nqi kho tshiab. Lub caij no, los ntawm kev tswj hwm cov lej, nws kuj tuaj yeem ua tau raws li cov kev tsis muaj zog ntawm cov hniav sib txawv, ntsuas kev coj tsis kam thiab tawv.
OVERALL Txheej Txheem Flow: Plaub Kaug Los Tswj Ua Kom Zoo
Laser Quenching thiab kho kom vam khom cov tshuab ua lag luam tshwj xeeb, thiab cov txheej txheem tag nrho tau muab faib ua plaub kauj ruam. Thawj kauj ruam yog workpiece clamping thiab lub iav loj loj yog siv los ua kom muaj kev sib koom tes ntawm lub ntsej muag (xws li cov cuab yeej ua haujlwm Laser thiab cov cuab yeej siab} Qhov thib ob kauj ruam yog hniav nto tshwm sim: Tom qab tshem cov roj stains thiab xeb, ua kom muaj zog}}}}} Cov chaw) kom dhau 80% txhawm rau kom ntseeg tau cov txiaj ntsig kev ua tiav. Qhov theem peb yog ntu kev ua lag luam laser: Raws li cov hniav ua kom zoo nkauj, thiab lub zog qis dua, lub zog qis dua, lub zog qis dua yog siv rau kev ntxhov siab. Kauj ruam thib plaub yog qhov ntsuas zoo soj ntsuam: tsis muaj kev npau taws yog qhov yuav tsum tau ua; Hloov chaw, kev tshuaj xyuas ncaj qha tau ua rau cov hniav tawv tawv, tawv tawv txheej qhov tob, thiab cladding txheej kom ua raws li cov qauv.
Cov Ntsiab Lus Tseem Ceeb ntawm Laser Quenching: Kho kom tswj tau ntawm cov nyhuv tawv tawv
Txheej txheem tsis ncaj qha txiav txim siab ua kom zoo thiab xav tau hloov kho raws li cov khoom siv iav (piv txwv li cov hlau, 40cr steel) thiab cov haujlwm ua haujlwm. Tus hniav nto hardness yog tswj ntawm rockwell hardness (HRC) 35 {}} {{luas bread xwm txheej; Nws tuaj yeem nce mus rau HRC 45-50 rau cov cai tshwj xeeb. Qhov tob ntawm lub hardened txheej yog 0.4-0.6mm, ntsuas qhov chaw coj tawm tsam thiab tseem ceeb cuam tshuam. Lub Laser Fais yog teeb ntawm 2.0-3.5KW: Tsawg heev lub zog yuav ua rau tsis muaj zog hnyav, thaum muaj zog ntau dhau yuav ua rau pom cov hniav. Lub quenching ceev (scanning ceev) yog 10-50mm / s-tus qeeb qeeb, ntxaum cov txheej hardened. Segmented hloov kho ntawm CNC system tuaj yeem ua tau raws li kev ua haujlwm xav tau ntawm cov khoom sib txawv.
Cov taw qhia txheej txheem ntawm laser cladding: adapting rau ntau yam kev xav tau
Laser Cladding yog cov ntsiab lus thev naus muag khoom yog qhov kho cov zog loj, thiab nws cov txheej txheem qhia tau hloov kho kom tau raws li qhov xav tau. Lub thickness ntawm cov cladding txheej yog kho raws li qhov tsis xws luag: rau kev hnav me me (0.2}} txheej cladding ntawm 0.3-0.8mm yog siv; Rau kev kho hniav tawg (1-2mm poob), ntau-txheej cladding ntawm 1.5-2.5mm yog saws, nrog cov interlayer kub tswj kom tiv thaiv cov kab nrib pleb. Lub hardness ntau ntawm cov cladding txheej yog HRC 25-60: HRC 40-55 yog xaiv rau cov hniav kom ntseeg tau, thaum HRC 25-35 yog siv rau cov hauv paus hniav txhawm rau txhim kho kev cuam tshuam. Rau cov ntaub ntawv xws li 45 hlau thiab 40cr steel, ncaj cladding yog ua tau yam tsis muaj qhov ua ntej, piv rau cov txheej txheem. Lub cladding txheej Cov ntaub ntawv ua rau daim ntawv sib txuas me me nrog cov kab nrib pleb
Cov Cheebtsam ntawm Laser Cladding System
Txo tus nqi txo, kev daws teeb meem, thiab txhawb nqa rau cov cuab yeej hnyav thiab txij nkawm
Daim ntawv thov ntawm laser quenching thiab kev kho tshuab siv rau cov zog loj nqa cov txiaj ntsig tseem ceeb thiab cov txiaj ntsig sib luag. Hais txog lub neej txuas ntxiv, lub siab- hardness quenched txheej tuaj yeem rub tawm lub iav pabcuam los ntawm 2 {{4 4}} 3 zaug. Hauv kev tswj tus nqi, tus nqi kho tau qis dua li ntawm kev hloov-tshwj xeeb rau lub zog loj tshaj 2m thiab qhov hnyav tshaj 10 tons, nyiaj txiag muaj txiaj ntsig zoo tshaj plaws. Hauv kev txhawb nqa ntau lawm, lub voj voog kho yog tsuas yog 1-3 hnub, ntau dua luv dua li 1-3 lub hlis ua tiav cov khoom siv tshiab, txo cov cuab yeej downtimes poob. Tam sim no, cov thev naus laus zis tau siv dav rau cov khoom siv tseem ceeb rau "kev lag luam ntsuab" thiab "kev ua haujlwm zoo thiab txij nkawm" ntawm cov cuab yeej hnyav.
