Lasers muaj revolutionized manufacturing, thiab ib tug ntawm cov tseem ceeb laser technologies yogtxias laser vuam. Tab sis dab tsi yog qhov txias laser vuam thiab nws ua haujlwm li cas? Cov kab lus no muab kev saib tob tob txog cov txheej txheem txias laser vuam, nws qhov zoo, thiab kev siv thoob plaws hauv kev lag luam.
Cold Laser Vuam yog dab tsi?
Txias laser vuam, tseem hu ua laser beam welding, siv lub teeb laser tsom ua ib qho chaw kub siab los koom ob daim hlau ua ke. Lub laser beam melts thiab fuses cov ntaub ntawv ntawm qhov sib koom ua ke yam tsis muaj cua sov tseem ceeb ntawm thaj chaw ib puag ncig.
Tsis zoo li cov txheej txheem vuam tsoos uas siv cov nplaim taws lossis hluav taws xob arcs, laser welding cia siab rau qhov sib txuam, monochromatic beam ntawm photons. Thaum lub tshuab hluav taws xob siab ceev laser tsoo rau saum npoo, nws sai sai heats, melts, thiab vaporizes cov khoom los tsim ib lub pas dej me me. Cov txheej txheem txias no tshwm sim sai heev uas cov cua sov tsis dissipate ntau dhau ntawm thaj chaw tam sim ntawd.
Cold Laser Vuam ua haujlwm li cas?
Thaum lub sij hawm txias laser vuam, ob qhov chaw yog tuav ua ke nyob rau hauv ib tug clamping fixture. Lub teeb pom kev zoo heev laser taug kev raws txoj kab sib koom ua ke los ua cov vuam. Cov txheej txheem muaj peb kauj ruam tseem ceeb:
1. Laser cua sov thiab melting - Lub laser beam nkag mus rau sab saum toj cov ntaub ntawv thiab heats li nyob rau hauv lub hauv paus kev sib koom seem tam sim ntawd tsim ib tug yaj pas dej ua ke.
2. Kev sib xyaw thiab fusion - Cov ntaub ntawv melted sib tov thiab ntws ua ke hauv qab qhov nro quab yuam kom ua tiav fusion.
3. Ceev ceev solidification - Cov khoom molten sai txias thiab solidifies raws li lub laser txav raws cov weld kab. Qhov no ua rau lub siab-lub zog daim ntawv cog lus.
Lub ntsiab kom zoo dua ntawm laser vuam yog cov concentrated tshav kub input. Tsuas yog ib qho me me ntawm cov khoom yuav tsum tau cua sov ua kom lub vuam, ua kom lub hauv paus hlau nyob ib puag ncig txias. Qhov no yog li cas cov txheej txheem muab lub npe "txias laser vuam."
Cov txiaj ntsig ntawm Cold Laser Vuam
Muaj ntau qhov txiaj ntsig tseem ceeb uas ua rau txias laser vuam zoo rau ntau daim ntawv thov:
- Tsawg kub distortion - Txij li tsuas yog ib cheeb tsam me me yuav tsum tau cua sov, qhov chaw raug thermal warping tsawg los yog shrinkage. Qhov no tso cai rau precision vuam ntawm cov khoom muag.
- Cov cua txias siab - Cov cua txias nrawm muab cov qauv zoo-grained weld nrog cov khoom siv kho kom zoo dua qub.
- Tsawg residual kev nyuaj siab - Lub laser ua rau tsawg distortion, ua rau txo qis residual stresses nyob rau hauv weld joint.
- Me me tshav kub-tshem tawm tsam - Lub tshav kub dissipates nyob rau hauv 0.04 nyob rau hauv (1 mm) ntawm cov weld, zam kev puas tsuaj rau cov khoom nyob ib puag ncig.
- Siab vuam ceev - Lasers muab ceev, zoo dua vuam piv rau cov tsoos vuam txoj kev.
- Yooj yim automated - Lub teeb laser tuaj yeem ua haujlwm thiab tswj tau meej rau cov khoom siv hluav taws xob siab.
- Kev nkag mus tob dua - Laser vuam tuaj yeem nkag mus thiab koom nrog cov ntu tuab ntawm cov hlau yooj yim dua.
- Txhim kho qhov zoo - Lub teeb laser zoo tsim kom du, tsis muaj kab nrib pleb, thiab zoo ib yam welds.
Kev siv Cold Laser Vuam
Nov yog qee qhov piv txwv ntawm kev lag luam siv txias laser vuam niaj hnub no:
- Aerospace - Cov khoom siv dav hlau thiab dav hlau xws li cov cav tsheb, cov khoom siv dav hlau, thiab cov turbines.
- Kev Kho Mob - Cov cuab yeej kho mob, cov cuab yeej phais mob, kev cog hniav orthopedic.
- Electronics - Roj teeb tabs, hluav taws xob tiv tauj, cov khoom siv hauv computer.
- Automotive - Lub rooj zaum ncej, tailor-welded blanks, kis qhov chaw.
- Cov khoom siv - Cov khoom siv siv xws li cov khoom sib tov, ntxhua khaub ncaws, tub yees.
- Cov hniav nyiaj hniav kub - Brazing hlau thiab alloys hauv cov nplhaib, watches, thiab chains.
Yuav luag txhua daim ntawv thov uas xav tau kev sib koom nrog hlau tuaj yeem tau txais txiaj ntsig los ntawm laser vuam. Qhov tseeb, cov khoom siv hluav taws xob hauv ib cheeb tsam ua rau cov khoom zoo, tsis muaj qhov sib txawv ntawm cov welds haum rau cov khoom me me thiab sib txawv.
Nyob rau hauv cov ntsiab lus, txias laser welding muab ib tug ceev, huv si, thiab npaum lwm txoj rau ib txwm welding hom kev kawm. Lub laser beam tsim muaj zog, meej welds nrog me ntsis cuam tshuam rau thaj chaw ib puag ncig. Raws li kev siv tshuab laser txuas ntxiv mus, txias laser vuam yuav txuas ntxiv mus rau hauv cov ntawv thov tshiab thoob plaws kev lag luam.
