Cov tsheb ciav hlau yog lub ntsiab lus tseem ceeb ntawm kev thauj mus los hauv ib lub tebchaws, los ntawm cov tsheb ciav hlau hlau mus rau cov tsheb ciav hlau ceev ceev, "qhov tshwm sim" ntawm cov tsheb ciav hlau tau nce siab dua, thiab cov txheej txheem yuav tsum tau ua rau kev vuam vuam tau nce siab dua. Vim yog cov txheej txheem vuam ib txwm muaj, muaj qee cov cim convex uas tsis tuaj yeem tiv thaiv los ntawm qhov chaw vuam pob qij txha, thiab kev sib khi ua haujlwm ntawm qhov chaw vuam qauv tsheb lub cev tsis zoo, thiab cov khoom siv EMU tsheb lub cev tsis tuaj yeem siv dav. . Nyob rau hauv xyoo tas los no, cov ntaub ntawv lub cev ntawm lub tsheb kuj tau ua los ntawm cov khoom siv hlau zoo tib yam rau cov hlau tsis muaj steel thiab aluminium alloy profiles, thiab cov ntaub ntawv hloov pauv tau coj mus rau kev txhim kho cov txheej txheem kev ua haujlwm, thiab cov thev naus laus zis ntawm laser welding kuj tau ua. tau nkag mus rau hauv kev tsim khoom thiab cov kab ntau lawm ntawm railway tsheb.
Raws li lub cev muaj zog, qhov kev xav tau ntawm kev sib txuas ntawm lub tsheb ciav hlau lub cev yog qhov siab heev, tsis tsuas yog muaj zog, tab sis kuj yog qhov loj me, ruaj khov hauv qhov zoo thiab zoo nkauj zoo nkauj. Cov khoom siv hlau siv hauv lub cev lub tsheb yuav tsum muaj peev xwm ua tau raws li lub zog ntawm lub tsheb lub cev, thiab muaj kev sib tsoo tsis kam, ua haujlwm ntev, hluav taws kub tsis kam, thiab siv tau dua tshiab. Cov tsheb tsis muaj steel hlau tau dhau los ua ib qho ntawm cov lus qhia tseem ceeb hauv kev txhim kho vim tias lawv cov kev cuam tshuam zoo rau lub zog nqus cov yam ntxwv, kev nyab xeeb hluav taws, lub teeb yuag thiab cov nqi tu qis. Txawm hais tias qhov vuam kev ua tau zoo ntawm cov hlau tsis xeb yog qhov zoo heev, tab sis lub cev tsis muaj steel hlau yog ib qho yooj yim los tsim thermal deformation piv nrog cov pa roj carbon zoo tib yam lub tsheb lub cev, yog li ntawd, nyob rau hauv lub nam ntawm rail tsheb, nyob rau hauv lub xyoo tsis ntev los no, nws yog tsuas yog lub splicing vuam. carbon steel thiab stainless hlau tsheb lub cev steel qauv nto txheej phaj, thiab lub laser vuam ntawm cov cua sov input qis, uas tsis yog-kev sib cuag, tuaj yeem txuas ntxiv welded yog txoj kev vuam zoo tshaj plaws. Tam sim no, kev siv lub ntsiab ntawm laser vuam tshuab vuam tshuab, laser vuam tuaj yeem txuas ntxiv vuam thiab foob vuam, kub siab, vuam deformation yog me me, lub flatness ntawm lub tsheb lub cev yog tsawg dua 1 hli, ua kom tiav cov tsos ntawm tsis muaj vuam. deformation, lub hom phiaj ntawm discoloration, los tsim ib tug zoo nkauj tsos, stainless hlau tsheb lub cev cov khoom uas tsis pleev xim rau, thiab tom qab lub laser vuam txheej txheem, lub zog zoo li qub thiab qaug zog lub zog ntawm lub tsheb. tau txhim kho, qhov zoo ntawm lub tsheb lub cev yog txo, lub sealing yog zoo, lub sab hauv zoo ntawm cov khoom thiab cov kev ua lag luam zoo yog zoo dua, thiab high-ceev EMU muaj pes tsawg leeg ntawm stainless hlau tsheb lub cev yog ua tau.
Qhov zoo ntawm precision vuam laser vuam tshuab:
1. Laser vuam tuaj yeem ua tiav qhov chaw vuam, taub qab vuam, sib tshooj vuam, foob vuam, thiab lwm yam rau cov ntaub ntawv nyias nyias thiab cov khoom zoo.
2. Lub zog laser yog loj, qhov vuam muaj qhov sib piv siab, qhov kub ntawm qhov cuam tshuam yog me me, qhov deformation me me, thiab vuam ceev yog ceev.
3. Qhov zoo ntawm cov weld yog siab, du thiab zoo nkauj, tsis muaj porosity, thiab lub toughness ntawm cov ntaub ntawv tom qab vuam yog tsawg kawg yog sib npaug ntawm cov khoom ntawm niam txiv.
4. Lub waveform tam sim no tuaj yeem hloov kho arbitrarily, thiab cov waveforms sib txawv tuaj yeem tsim raws li cov khoom siv vuam sib txawv, kom cov vuam tsis sib xws thiab cov kev xav tau vuam tuaj yeem sib phim kom ua tiav cov txiaj ntsig zoo vuam.
