Laser vuam txheej txheem
Nws yog tshwj xeeb muaj nuj nqis thiab dav siv nyob rau hauv kev lag luam automotive, qhov twg automotive panels yog ib qho ntawm tsib pawg loj ntawm laser vuam.
Siv hauv tsheb, nws tuaj yeem txo qhov hnyav ntawm lub cev lub cev, txhim kho kev sib dhos ntawm lub tsheb lub cev, ua kom lub cev nruj ntawm lub tsheb, thiab txo cov nqi stamping thiab sib dhos hauv cov txheej txheem tsim khoom ntawm lub cev tsheb.
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
Laser self-fusion pawg vuam txheej txheem rau tsheb vaj huam sib luag qhov chaw
Thaum lub laser beam nrog lub hwj chim ceev mus txog ib tug tej yam ntau yam (106 ~ 107 W / cm2) irradiates saum npoo ntawm cov khoom, cov khoom absorbs lub teeb lub zog thiab converts nws mus rau hauv lub tshav kub zog. Cov khoom yog rhuab, melted, thiab vaporized, ua ib tug loj npaum li cas ntawm cov hlau vapor, uas khiav tawm ntawm qhov chaw. Nyob rau hauv cov tshuaj tiv thaiv quab yuam tsim los ntawm lub laser, cov kua hlau molten raug thawb ib ncig los ua pits. Raws li lub laser txuas ntxiv mus rau irradiated, lub pits nkag mus tob. Thaum lub laser nres irradiating, cov kua molten nyob ib ncig ntawm lub pits ntws rov qab thiab txias thiab solidifies. Weld ob workpieces ua ke.
Yam cuam tshuam rau laser vuam
1. Laser zog
Nyob rau hauv lub laser welding muaj lub zog ceev ceev. Hauv qab no tus nqi, tsuas yog nto melting ntawm lub workpiece tshwm sim, thiab qhov nkag mus tob yog heev ntiav, uas yog, lub vuam yog ua nyob rau hauv ib tug ruaj khov kub conduction hom; Thaum tus nqi no tau mus txog lossis dhau lawm, cov ntshav yuav raug tsim tawm, uas yog ib qho cim ntawm Kev nce qib ntawm kev sib sib zog nqus sib sib zog nqus welding, qhov nkag mus tob yuav nce ntxiv. Yog tias lub zog laser qis dua qhov pib no thiab lub zog laser lub zog me me, kev nkag mus tsis txaus yuav tshwm sim thiab txawm tias cov txheej txheem vuam yuav tsis ruaj khov.
2. Vuam ceev
Qhov vuam ceev muaj qhov cuam tshuam zoo rau kev nkag mus tob. Kev ua kom nrawm yuav ua rau qhov nkag mus ntiav ntiav, tab sis yog tias qhov ceev qis dhau, nws yuav ua rau cov khoom tawg ntau dhau thiab vuam ntawm lub workpiece. Yog li ntawd, muaj qhov tsim nyog vuam ceev ntau yam rau cov khoom siv tshwj xeeb nrog qee lub zog laser thiab qee qhov tuab, thiab qhov kev nkag siab siab tshaj plaws tuaj yeem tau txais ntawm tus nqi sib xws.
3. Defocus tus nqi
Txhawm rau kom muaj lub zog txaus txaus, qhov chaw ua kom pom tseeb yog qhov tseem ceeb. Nyob rau txhua lub dav hlau deb ntawm lub laser tsom, lub zog ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Muaj ob hom defocus: zoo defocus thiab tsis zoo defocus. Thaum lub dav hlau focal nyob saum lub workpiece, nws yog qhov zoo defocus, thiab thaum nws nyob saum lub workpiece, nws yog qhov tsis zoo defocus. Cov kev hloov hauv defocus ncaj qha cuam tshuam rau qhov dav thiab qhov tob ntawm qhov vuam.
4. Cov roj tiv thaiv
Thaum lub sij hawm lub laser vuam txheej txheem, inert gases feem ntau yog siv los tiv thaiv lub pas dej ua ke, tab sis nyob rau hauv feem ntau daim ntaub ntawv, gases xws li argon, nitrogen, thiab helium feem ntau yog siv los tiv thaiv lub workpiece los ntawm oxidation thaum lub sij hawm vuam txheej txheem thiab tshuab mus. lub plasma.
