Laser npav tau dhau los ua qhov tseem ceeb tshaj plaws hauv kev tsim kho kev lag luam aviation
Txij li thaum yug los ntawm high-power laser li nyob rau hauv 1970s, laser welding, laser txiav, laser drilling, laser nto kho, laser alloying, laser cladding, laser prototyping sai sai, laser ncaj qha tsim ntawm hlau qhov chaw thiab ntau tshaj li kaum daim ntawv thov.
Laser machining yog lub zog, hluav taws kub thiab hluav taws xob machining tom qab ib tug tshiab ua technology, nws muaj peev xwm daws tau cov ntaub ntawv sib txawv ua, zoo meej thiab xav txog tej yam teeb meem, xws li tsim thiab refining txij li thaum muaj zog laser ntaus ntawv yug los ntawm lub 70s, tau tsim lub laser vuam. , laser txiav, laser khij, laser doping kaum tawm, yooj yim rau kev ua kom zoo, kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig thiab lwm yam Qhov zoo tshaj plaws, ceev tsheb, electronics, aerospace, machinery, ships, yuav luag tag nrho cov cheeb tsam ntawm lub teb chaws kev khwv nyiaj txiag tau lug siv, hu ua "manufacturing system common means of processing".
Ua raws li cov hauv qab no
1.Laser txiav tshuab nyob rau hauv aerospace teb ntawm daim ntawv thov
Hauv kev lag luam aerospace, laser txiav cov ntaub ntawv yog: lub puab tsaig alloy, npib tsib xee alloy, chromium alloy, aluminium alloy, stainless hlau, chin acid tseem ceeb, yas thiab cov ntaub ntawv sib xyaw.
Hauv kev tsim cov cuab yeej siv dav hlau, lub plhaub ntawm kev siv cov khoom siv tshwj xeeb hlau, siab zog, siab hardness, kub resistant, zoo tib yam txiav txoj kev yog ib qho nyuaj rau ua kom tiav cov khoom ua, laser txiav yog ib yam ntawm cov kev ua tau zoo, muaj peev xwm. siv laser txiav kev ua tau zoo, cov qauv honeycomb, lub moj khaum, tis, tail ncua kev kawm phaj, lub nyoob hoom qav taub lub ntsiab rotor, cav lub thawv thiab nplaim taws, thiab lwm yam.
Laser txiav feem ntau sivnruam tso zis laser, tab sis kuj tseem siv tau ntau zaus carbon dioxide mem tes laser.Laser txiav qhov tob rau qhov dav piv yog siab, rau cov hlau tsis yog hlau, qhov tob rau qhov dav piv tuaj yeem ncav cuag ntau tshaj 100, hlau tuaj yeem ncav cuag li 20;
Laser txiavceev yog siab, txiav lub puab tsaig alloy daim ntawv yog 30 zaug hais txog tus neeg kho tshuab txoj kev, txiav steel phaj yog 20 zaug hais txog cov neeg kho tshuab txoj kev;
Laser txiavzoo yog zoo.Piv nrog rau oxy-acetylene thiab plasma txiav txoj kev, txiav carbon steel muaj qhov zoo tshaj plaws.Lub tshav kub cuam tshuam ntawm laser txiav yog oxy-acetylene nkaus xwb.
2.Application ntawm laser vuam tshuab nyob rau hauv aerospace teb
Hauv kev lag luam aerospace, ntau qhov chaw yog welded nrog electron beam, vim laser vuam tsis tas yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev, laser vuam yog siv los hloov electron beam vuam.
Rau lub sijhawm ntev, kev sib txuas ntawm cov khoom siv dav hlau tau siv cov cuab yeej rov qab riveting, lub ntsiab yog vim li cas aluminium alloy siv hauv cov qauv dav hlau yog kev kho cua sov reinforced aluminium alloy (ie, siab zog aluminium alloy), ib zaug fusion. vuam, kev kho cua sov ntxiv dag zog yuav ploj, thiab cov kab nrib pleb yog qhov nyuaj los zam.
Kev siv tshuab laser vuam kov yeej cov teeb meem no thiab ua kom yooj yim rau kev tsim cov txheej txheem ntawm lub fuselage, txo qhov hnyav ntawm lub fuselage los ntawm 18% thiab tus nqi los ntawm 21.4% ~ 24.3%.Laser vuam tshuab yog kev hloov kho thev naus laus zis hauv kev lag luam dav hlau tsim.
3.Application ntawm laser drilling tshuab nyob rau hauv aerospace teb
Laser drilling tshuab yog siv nyob rau hauv kev lag luam aerospace los laum qhov ntawm qhov ntsuas lub pov haum bearings, cua txias turbine hniav, nozzles thiab combustors.Tam sim no, laser drilling yog txwv rau qhov txias qhov ntawm qhov chaw nres tsheb ntawm lub cav, vim tias muaj cov kab nrib pleb ntawm qhov chaw ntawm lub qhov.
Kev sim kawm ntawm laser beam, electron beam, electro chemistry, EDM drilling, mechanical drilling thiab xuas nrig ntaus yog xaus lus los ntawm kev tsom xam.Laser drilling muaj qhov zoo ntawm cov nyhuv zoo, muaj zog versatility, high efficiency thiab tsawg tus nqi.
4.Application ntawm laser nto technology nyob rau hauv aerospace teb
Laser cladding yog ib qho tseem ceeb ntawm cov khoom siv kho qhov chaw.Nyob rau hauv aviation, tus nqi ntawm spare qhov chaw rau aero-engines yog siab, yog li nyob rau hauv ntau zaus nws yog nqi-zoo los kho qhov chaw.
Txawm li cas los xij, qhov zoo ntawm cov khoom kho yuav tsum ua kom tau raws li qhov yuav tsum tau muaj kev nyab xeeb.Piv txwv li, thaum muaj kev puas tsuaj tshwm nyob rau saum npoo ntawm lub dav hlau propeller hniav, nws yuav tsum tau kho nrog ib co deg kho technology.
Ntxiv nrog rau lub zog siab thiab qaug zog ua haujlwm xav tau los ntawm cov kiv cua, qhov kev tiv thaiv corrosion tom qab kho qhov chaw yuav tsum tau xav txog.Laser cladding tshuab siv tau los kho 3D nto ntawm lub cav hniav.
5.Application of laser forming technology nyob rau hauv aerospace teb
Daim ntawv thov ntawm laser txoj kev tsim technology nyob rau hauv aviation yog ncaj qha cuam tshuam nyob rau hauv lub ncaj qha manufacturing ntawm titanium alloy structural qhov chaw rau aviation thiab kev kho sai ntawm aircraft engine qhov chaw.
Laser txoj kev tsim tshuab tau dhau los ua ib qho ntawm cov tseem ceeb tshiab tsim thev naus laus zis rau loj titanium alloy structural seem ntawm aerospace tiv thaiv riam phom thiab khoom siv.Txoj kev tsim khoom ib txwm muaj qhov tsis zoo ntawm tus nqi siab, lub sijhawm npaj ntev ntawm forging pwm, ntau cov khoom siv thiab cov khoom siv tsawg.
