Kuyika chizindikiro kwa laser kwakhala mwayi wofunikira kwambiri pakukula kwamakampani oyendetsa ndege
Kuyambira kubadwa kwa zida zamphamvu kwambiri za laser m'zaka za m'ma 1970, kuwotcherera kwa laser, kudula kwa laser, kubowola laser, mankhwala a laser pamwamba, laser alloying, laser cladding, laser mofulumira prototyping, laser mwachindunji kupanga ziwalo zachitsulo ndi ntchito zoposa khumi ndi ziwiri.
Laser Machining ndi mphamvu, moto ndi magetsi Machining pambuyo ukadaulo watsopano processing, akhoza kuthetsa zosiyanasiyana processing zipangizo, wangwiro ndi woganiza bwino mavuto luso, monga kupanga ndi kuyenga kuyambira mkulu mphamvu laser chipangizo anabadwa wa 70s, wapanga laser kuwotcherera. , laser kudula, laser chodetsa, laser doping ambiri ntchito monga ndondomeko, poyerekeza ndi miyambo processing njira, laser processing ali ndi zambiri mkulu-mphamvu wandiweyani kuganizira, zosavuta ntchito, kusinthasintha mkulu, apamwamba, kuteteza mphamvu ndi kuteteza chilengedwe ndi zina. Ubwino wodziwika, magalimoto othamanga, zamagetsi, zakuthambo, makina, zombo, pafupifupi kuphatikiza madera onse a chuma cha dziko lapansi akhala akugwiritsidwa ntchito kwambiri, omwe amadziwika kuti "njira yopangira zinthu zodziwika bwino".
Gwiritsani ntchito mbali zotsatirazi
1.Laser kudula luso m'munda Azamlengalenga ntchito
M'makampani azamlengalenga, zida zodulira laser ndi: chibwano aloyi, faifi tambala, aloyi chromium, aloyi zotayidwa, chitsulo chosapanga dzimbiri, chibwano asidi kiyi, pulasitiki ndi gulu zipangizo.
Popanga zida zakuthambo, chipolopolo chogwiritsa ntchito zida zapadera zachitsulo, mphamvu yayikulu, kuuma kwakukulu, kupirira kutentha kwambiri, njira yodulira wamba ndizovuta kumaliza kukonza zinthu, kudula kwa laser ndi njira yabwino yopangira. gwiritsani ntchito laser kudula processing, kapangidwe ka zisa, chimango, mapiko, mbale yoyimitsidwa mchira, rotor yayikulu ya helikopita, bokosi la injini ndi chubu lamoto, etc.
Laser kudula zambiri ntchitomosalekeza linanena bungwe laser, komanso zothandiza mkulu pafupipafupi mpweya woipa kugunda laser.Laser kudula kuya m'lifupi chiŵerengero ndi mkulu, chifukwa sanali zitsulo, kuya ndi m'lifupi chiŵerengero akhoza kufika oposa 100, zitsulo akhoza kufika pafupifupi 20;
Laser kudulaliwiro ndi lalitali, kudula chibwano aloyi pepala ndi nthawi 30 za njira makina, kudula zitsulo mbale ndi nthawi 20 za njira makina;
Laser kudulakhalidwe ndi labwino.Poyerekeza ndi njira zodulira oxy-acetylene ndi plasma, kudula chitsulo cha kaboni kuli ndi khalidwe labwino kwambiri.Malo okhudzidwa ndi kutentha kwa laser kudula ndi oxy-acetylene kokha.
2.Kugwiritsa ntchito luso la laser kuwotcherera m'munda wamlengalenga
M'makampani azamlengalenga, magawo ambiri amawotcherera ndi mtengo wa elekitironi, chifukwa kuwotcherera kwa laser sikuyenera kuchitidwa mu vacuum, kuwotcherera kwa laser kumagwiritsidwa ntchito m'malo mwa kuwotcherera kwa ma elekitironi.
Kwa nthawi yayitali, kugwirizana pakati pa zigawo zapangidwe za ndege zakhala zikugwiritsidwa ntchito pogwiritsa ntchito luso lakumbuyo lakumbuyo, chifukwa chachikulu ndi chakuti zitsulo zotayidwa zomwe zimagwiritsidwa ntchito mu ndege zimapangidwira kutentha kwazitsulo zotayidwa (ie, aluminium alloy alloy), kamodzi kokha kuwotcherera, kutentha mankhwala kulimbikitsa zotsatira adzatayika, ndi intergranular ming'alu n'zovuta kupewa.
Kukhazikitsidwa kwaukadaulo wa kuwotcherera kwa laser kumathetsa zovuta zotere ndipo kumachepetsa kwambiri njira yopangira fuselage ya ndege, kuchepetsa kulemera kwa fuselage ndi 18% ndi mtengo wake ndi 21.4% ~ 24.3%.Ukadaulo wowotcherera wa laser ndikusintha kwaukadaulo pamakampani opanga ndege.
3.Kugwiritsa ntchito luso la laser pobowola m'munda wamlengalenga
Ukadaulo wakubowola wa laser umagwiritsidwa ntchito pobowola mabowo pazitsulo zamtengo wapatali, masamba a turbine oziziritsidwa ndi mpweya, ma nozzles ndi zoyatsira moto.Pakalipano, kubowola kwa laser kumangokhala mabowo ozizira a injini zoyima, chifukwa pamwamba pa mabowowo pali ming'alu ya microscopic.
Kafukufuku woyeserera wa laser mtengo, mtengo wa elekitironi, chemistry yamagetsi, kubowola kwa EDM, kubowola kwamakina ndi kukhomerera kumatsirizidwa ndi kusanthula kwathunthu.Kubowola kwa laser kuli ndi zabwino zake, kusinthasintha kwamphamvu, kuchita bwino kwambiri komanso mtengo wotsika.
4.Kugwiritsa ntchito ukadaulo wa laser pamwamba pamunda wamlengalenga
Laser cladding ndichinthu chofunikira kwambiri chosinthira ukadaulo wapamwamba.Pa ndege, mtengo wa zida zosinthira za injini za aero ndi wokwera, choncho nthawi zambiri zimakhala zotsika mtengo kukonza zida.
Komabe, ubwino wa zigawo zokonzedwa ziyenera kukwaniritsa zofunikira za chitetezo.Mwachitsanzo, pamene chiwombankhanga chikawonongeka pamwamba pa chopangira ndege, chiyenera kukonzedwa ndi umisiri wina wamankhwala.
Kuphatikiza pa mphamvu yayikulu komanso kukana kutopa komwe kumafunikira ndi ma propeller blade, kukana kwa dzimbiri pambuyo pokonzanso pamwamba kuyenera kuganiziridwanso.Laser cladding luso angagwiritsidwe ntchito kukonza 3D pamwamba pa injini tsamba.
5.Kugwiritsa ntchito luso la laser kupanga m'munda wamlengalenga
Kugwiritsidwa ntchito kwaukadaulo wopanga ma laser pakuyendetsa ndege kumawonekera mwachindunji pakupangira zida za titaniyamu aloyi zopangira ndege komanso kukonza mwachangu magawo a injini za ndege.
Ukadaulo wopangira ma laser wakhala imodzi mwamakina atsopano opanga zida zazikulu za titaniyamu alloy zida ndi zida zodzitetezera mumlengalenga.The chikhalidwe kupanga njira ali kuipa kwa kukwera mtengo, yaitali kukonzekera nthawi ya forging nkhungu, kuchuluka kwa mawotchi processing ndi otsika mtengo zinthu magwiritsidwe ntchito.
