Kev txiav thiab tho tshuab: Txhua qhov kev siv thev naus laus zis thev naus laus zis, tshwj tsis yog qee qhov xwm txheej uas nws tuaj yeem pib ntawm ntug ntawm lub phaj, feem ntau yuav tsum tau tho qhov me me hauv lub phaj. Yav dhau los, ntawm laser stamping composite cov cav tov, ib lub punch tau siv los ua ntej tsim lub qhov, thiab tom qab ntawd lub laser tau siv los txiav los ntawm lub qhov me me. Rau laser txiav tshuab yam tsis muaj lub tshuab stamping, muaj ob txoj kev tho qhov yooj yim:
(1) Blasting piercing: Tom qab txuas ntxiv laser irradiation, ib lub qhov yog tsim nyob rau hauv nruab nrab ntawm cov khoom. Tom qab ntawd, cov pa oxygen flow coaxial nrog lub laser beam sai sai tshem tawm cov khoom molten los ua ib lub qhov. Qhov loj ntawm lub qhov feem ntau cuam tshuam nrog lub phaj thickness. Qhov nruab nrab txoj kab uas hla ntawm blasting piercing yog ib nrab ntawm lub phaj thickness. Yog li ntawd, rau cov phaj tuab, qhov blasting piercing qhov txoj kab uas hla yog loj dua thiab tsis puag ncig, ua rau nws tsis tsim nyog rau siab - qhov yuav tsum tau muaj (xws li roj tshuaj ntsuam kav), thiab tsuas yog haum rau cov khoom seem. Tsis tas li ntawd, txij li cov pa oxygen siab siv rau kev tho yog tib yam li thaum lub sij hawm txiav, muaj qhov tseem ceeb spatter.
(2) Pulse piercing: Lub siab -peak- lub zog pulse laser yog siv los yaj lossis vaporize cov khoom me me. Cua lossis nitrogen feem ntau yog siv los ua cov pa roj kom txo qhov kev nthuav dav vim exothermic oxidation. Cov roj siab yog qis dua cov pa oxygen thaum txiav. Txhua lub laser pulse tsim tsuas yog me me, nkag mus tob zuj zus; Yog li ntawd, tho cov phaj tuab siv sijhawm ob peb feeb. Thaum tho qhov ua tiav, cov pa pab cuam tam sim ntawd hloov nrog oxygen rau kev txiav ntxiv.
Tsis tas li ntawd, pulse piercing yuav tsum muaj kev txhim khu kev qha roj hluav taws xob tswj kev hloov pauv ntawm cov roj hom thiab kev kub siab, thiab tswj lub sijhawm tho. Hauv kev pulse tho, cov txheej txheem kev hloov pauv ntawm pulse piercing nrog workpiece nyob ruaj ruaj mus tas li, tas li - txiav ceev yog qhov tseem ceeb heev kom tau txais cov kev txiav zoo siab -.
