Nyob rau hauv cov txheej txheem ntawm kev tsim tsheb, laser tshuab yog tsuas yog siv rau lub cev ua ke ntawm cov hlau tsis sib xws, lub cev vuam thiab nws pib qhov vuam. Laser vuam siv rau lub tsheb tuaj yeem txo qhov hnyav ntawm lub cev thiab ua tiav lub hom phiaj ntawm kev txuag roj; txhim kho kev sib dhos qhov tseeb ntawm lub cev, kom cov tawv nqaij ntawm lub cev zoo tuaj, yog li txhim kho kev nyab xeeb ntawm lub cev; txo cov nqi stamping thiab sib dhos hauv cov txheej txheem tsim khoom ntawm lub cev tsheb, txo cov naj npawb ntawm lub cev thiab txhim kho kev sib koom ua ke ntawm lub cev.
Laser self-fusion vuam
Laser self-fusing welding, nyob rau hauv uas ob los yog ntau tshaj qhov chaw ntawm ib tug weld yaj thiab nws thiaj li txias los tsim ib chav tsev, tsis tas yuav tsum tau ntxiv cov auxiliary fluxes los yog muab tub lim thiab siv lub workpiece tus kheej cov ntaub ntawv los fuse ua ke.
Laser self-fusion vuam nyob rau hauv nws pib lub cev raug muab faib ua ob lub ntsiab: lub cev sib dhos vuam thiab sib dhos vuam.
Lub cev sib dhos welding
Tab sis nrog txoj kev loj hlob ntawm kev siv tshuab, laser vuam yog ntau thiab dav siv nyob rau hauv no feem ntawm vuam, tsuas yog Volvo tseem insisting siv laser self-fusion vuam; rau sab ib puag ncig, Ford SUV thiab sedan muaj lub laser self-fusion vuam, thiab ntau cov qauv ntawm Volkswagen kuj siv nws.
Automotive laser vuam
Tailor-welded blank (TWB) yog ua los ntawm cov sib txawv zog, txawv thickness los yog txawv txheej ntawm hlau vuam, vim qhov zoo ntawm laser vuam efficiency, zoo weld seam forming, thiab lwm yam., tam sim no automotive vuam phaj yog ua los ntawm laser vuam.
Piv nrog rau cov hlau zoo tib yam, qhov zoo ntawm cov welded panels yog nyob rau hauv peb yam nram qab no: 1:
1. txo lub cev hnyav - siv txoj kev vuam los txhim kho lub thickness ntawm daim ntawv kom txo qhov hnyav;
2. txhim kho lub cev kev pabcuam thiab kev sib tsoo - feem ntau suav nrog kev nyab xeeb, kev ua haujlwm ntawm kev tsav tsheb, qaug zog thiab corrosion kuj thiab lub cev rigidity;
3. kev txo nqi - feem ntau ntawm cov khoom siv txo, txo cov txheej txheem thiab txo cov cuab yeej.
Kev siv cov laser vuam phaj hauv lub cev tsim tuaj yeem txo cov naj npawb ntawm cov khoom, pwm thiab vuam cuab yeej, txo qhov hnyav thiab tus nqi ntawm lub cev, thiab txhim kho kev sib tw ntawm cov khoom lag luam. Daim duab 3 qhia txog cov kev siv tseem ceeb ntawm cov phaj vuam hauv lub tsheb lub cev-hauv-dawb, feem ntau yog nyob rau hauv cov ntaub, tab sis kuj muaj qee qhov kev siv hauv cov khoom siv.
Automotive manufacturing laser vuam tshuab siv
Vuam seam daim ntawv
Automotive vuam phaj raws li hom vuam seam kev faib tawm tuaj yeem muab faib ua peb pawg: 1:
1. ib leeg linear weld seam;
2. plural linear welds;
3. non-linear vuam seam.
Ntawm lawv, ib leeg-linear weld hom yog siv ntau tshaj plaws, thiab cov txheej txheem ntau lawm kuj yooj yim. Non-linear welds yog qhov nyuaj tshaj plaws, thiab feem ntau yog tsim raws li cov duab ntawm lub stamped ib feem tom qab tsim, thiaj li los txhim kho lub zog thiab stamping kev ua tau zoo ntawm cov khoom.
Txij li thaum tom ntej stamping thiab tsim cov automotive welded daim hlau yog yuav tsum tau, qhov zoo ntawm cov welded daim hlau thiab kev tswj ntawm qhov tsis xws luag yog tshwj xeeb tshaj yog nruj. Cov kev cai tseem ceeb muaj xws li cov tsos mob (pob txha, kab nrib pleb, inclusions, qhov thiab khawb, thiab lwm yam), weld tsim (weld dav, qog protrusion, zoo qhov tob ntawm weld, rov qab so thiab weld misalignment, thiab lwm yam) thiab mechanical zog (tensile, cupping) , hardness thiab dabtsi yog khoov kuaj ntawm lub vuam). Piv txwv li, nws yuav tsum tau hais tias lub tensile zog xeem puas nyob rau hauv lub cheeb tsam uas tsis yog-weld, thiab hais tias qhov chaw tawg nyob rau hauv lub cupping xeem yuav tsum tsis txhob nyob rau hauv lub weld los yog muaj ib tug cupping tus nqi ntau tshaj li tus nqi teev.
