Laser txiav yog irradiate lub laser beam ntawm cov khoom yuav tsum tau txiav, kom cov khoom yog rhuab mus thiab melted thiab vaporized, thiab cov yaj yog cua tshuab nrog high-pressure gas los tsim ib lub qhov, thiab ces lub beam tsiv mus nyob rau ntawm qhov chaw. cov khoom, thiab lub qhov tsis tu ncua ua ib tug txiav seam.
Feem ntau cov txheej txheem thermal txiav, tshwj tsis yog qee qhov xwm txheej, uas tuaj yeem pib ntawm ntug ntawm lub phaj, feem ntau ntawm lawv yuav tsum tau muab lub qhov me me rau hauv lub phaj thiab tom qab ntawd pib txiav los ntawm lub qhov me me.
Laser perforation txoj cai
Lub hauv paus ntsiab lus ntawm laser perforation yog: thaum ib tug npaum li cas ntawm laser beam yog irradiated rau saum npoo ntawm cov hlau ntawv, ntxiv rau ib feem ntawm lub reflection, lub zog absorbed los ntawm cov hlau ua rau cov hlau yaj los ua ib tug hlau melting pas dej ua ke. .Qhov nqus ntawm cov hlau molten txheeb ze rau cov hlau nto nce, uas yog, nws tuaj yeem nqus tau ntau lub zog los ua kom cov hlau melting.Lub sijhawm no, kev tswj xyuas kom zoo ntawm lub zog thiab huab cua siab tuaj yeem tshem tawm cov hlau molten nyob rau hauv lub pas dej molten thiab txuas ntxiv mus tob rau hauv lub pas dej molten kom txog thaum nws nkag mus rau hauv cov hlau.
Hauv kev siv tswv yim, perforation feem ntau muab faib ua ob txoj kev: pulse perforation thiab tawg perforation.
01 mem tes tho qhov
Lub hauv paus ntsiab lus ntawm pulse perforation yog siv lub laser pulse nrog lub siab ncov lub zog thiab lub voj voog qis rau irradiate lub phaj kom txiav, kom cov khoom me me yog yaj los yog vaporized, thiab txoj kab uas hla perforated yog tawm raws li kev sib koom ua ke ntawm nruam tshuab thiab auxiliary gases, thiab tseem maj mam nkag mus rau lub phaj.
Lub sij hawm ntawm laser irradiation yog sib quas ntus, thiab qhov nruab nrab lub zog siv yog kuj tsis tshua muaj, yog li lub tshav kub absorbed los ntawm tag nrho cov txheej txheem cov khoom yog me me.Residual tshav kub nyob ib ncig ntawm lub perforation muaj tsawg dua cov nyhuv thiab tsawg residue nyob rau hauv lub perforation site.Cov qhov pierced li no kuj ntau dua li niaj zaus thiab me me, thiab muaj me ntsis cuam tshuam rau qhov pib txiav.
Cov txheej txheem yog pom nyob rau hauv daim duab hauv qab no: tom qab lub laser beam yog irradiated rau cov khoom tiav, qhov saum npoo ntawm cov khoom yog thawj rhuab, raws li qhia nyob rau hauv (A); raws li cov cua kub maj mam deepens, nws plays lub luag hauj lwm ntawm perforation, uas. yog, (B) ~ (C) ~ (D).) mus txog thaum qhov kev nkag mus rau qhov kawg (E).Tag nrho cov txheej txheem tho tsis ua tiav ib zaug, tab sis ntau zaus hauv ib kauj ruam dhau los, maj mam sib sib zog nqus, kom txog thaum nkag mus.Yog li ntawd, txoj kev muaj lub sijhawm ntev perforation;Txawm li cas los xij, qhov tshwm sim yog me dua thiab muaj kev cuam tshuam thermal tsawg rau ib puag ncig.

Blasting perforation
Lub hauv paus ntsiab lus ntawm blasting perforation: ib qho nyiaj ntawm qhov nruam-yoj laser beam yog irradiated ntawm cov khoom ua tiav, kom nws absorbs ib tug loj npaum li cas ntawm lub zog thiab melts, tsim ib lub qhov, thiab ces cov auxiliary gas tshem tawm cov khoom molten los ua ib tug loj npaum li cas ntawm lub zog thiab melts. qhov kom ua tiav lub hom phiaj ntawm kev nkag mus sai.
Vim lub irradiation tsis tu ncua ntawm lub laser, lub aperture ntawm lub blasting perforation yog loj, thiab cov txaws yog hnyav dua, uas yog tsis haum rau txiav nrog ntau dua precision yuav tsum tau.
Tag nrho cov txheej txheem yog qhia nyob rau hauv daim duab saum toj no: lub tsom xam yog teem rau saum npoo ntawm cov khoom, thiab lub pore loj ntawm lub perforation yog nce kom sov sai sai.Txawm hais tias txoj kev no ntawm perforation tsim ib tug loj npaum li cas ntawm cov hlau molten thiab sputters mus rau saum npoo ntawm cov khoom tiav, nws muaj peev xwm txo tau lub sij hawm tho.
Qhov tshwm sim tiag tiag ntawm ob txoj kev tho yog qhia hauv daim duab hauv qab no.Feem ntau, pulse perforation zoo yog zoo dua li blasting perforation.
Qhov kev sim no siv GW5M series multi-module 12KW siab zog laser.Qhov zoo ntawm cov khoom no: siv 976nm technology, electro-optical conversion tus nqi ntau dua 45%, txo nqi hluav taws xob tsawg;ntau tshaj ib hom high-power modular tsim, cov khoom yog ntau compact, zoo stability, me me, sib zog;super ABR anti-reflective muaj peev xwm, yooj yim los txiav kub, nyiaj, tooj liab, txhuas thiab lwm yam ntaub ntawv zoo heev;zoo heev HBF siab ci ntsa iab sab saum toj tuag tso zis, zoo heev tuab phaj txiav vuam kev ua tau zoo.
Nws tuaj yeem siv rau tuab phaj txiav, vuam, cladding, thiab lwm yam.;nws muaj ntau yam scenario siv nyob rau hauv aviation, shipbuilding, tsheb thiab lwm yam lag luam.
