Laser yekumaka yave yakakosha tekinoroji mukana mukusimudzira indasitiri yekubhururuka
Kubva pakazvarwa michina ine simba repamusoro-soro muma1970s, laser welding, laser kucheka, laser drilling, laser surface treatment, laser alloying, laser cladding, laser kukurumidza prototyping, laser yakananga kuumbwa kwezvikamu zvesimbi uye zvinopfuura gumi nemaviri kunyorera.
Laser machining isimba, moto uye magetsi machining mushure meiyo nyowani yekugadzirisa tekinoroji, inogona kugadzirisa akasiyana magadzirirwo emidziyo, akakwana uye anofungisisa matambudziko ehunyanzvi, akadai sekugadzira uye kukwenenzvera kubvira simba repamusoro laser mudziyo wakazvarwa kubva kuma70s, wakagadzira iyo laser welding. , laser yekucheka, laser yekumaka, laser doping akawanda ekushandisa senge maitiro, zvichienzaniswa nemaitiro echinyakare ekugadzirisa, Laser kugadzirisa kune yakanyanya-yakanyanya simba dense kutarisisa, nyore kushanda, kuchinjika kwepamusoro, mhando yepamusoro, kuchengetedza kwesimba uye kuchengetedza kwezvakatipoteredza uye zvimwe zvakakurumbira zvakanakira, kukurumidza mota, zvemagetsi, aerospace, michina, ngarava, dzinenge dzinosanganisira nzvimbo dzese dzehupfumi hwenyika zvakashandiswa zvakanyanya, inozivikanwa se "manufacturing system common means of processing".
Shandisa kuzvinhu zvinotevera
1.Laser yekucheka tekinoroji mumunda weaerospace yekushandisa
Muindasitiri yemuchadenga, laser yekucheka zvinhu ndeiyi: chin alloy, nickel alloy, chromium alloy, aluminium alloy, simbi isina tsvina, chin acid kiyi, mapurasitiki uye zvinhu zvinosanganiswa.
Mukugadzirwa kwemidziyo yemuchadenga, goko rekushandiswa kwezvinhu zvakakosha zvesimbi, kusimba kwepamusoro, kuomarara kwepamusoro, kupisa kwakanyanya, nzira yekucheka yakajairika yakaoma kupedzisa kugadzira zvinhu, laser yekucheka imhando yenzira inoshanda yekugadzirisa, inogona. shandisa laser yekucheka kugadzirisa kunyatsoita, iyo yezinga rehuchi chimiro, dhizaini, mapapiro, muswe wakamiswa ndiro, iyo helikopta main rotor, injini bhokisi uye murazvo chubhu, nezvimwe.
Laser kucheka kazhinji kushandiswainoenderera yakabuda laser, asiwo inobatsira yakakwirira frequency carbon dioxide pulse laser. Laser yekucheka kudzika kusvika pahupamhi reshiyo yakakwira, kune isiri-simbi, kudzika kusvika kuhupamhi reshiyo inogona kusvika kupfuura zana, simbi inogona kusvika makumi maviri;
Laser kuchekakumhanya kwakakwira, kucheka chirebvu alloy sheet ndeye 30 nguva nezve mechanical nzira, yekucheka simbi ndiro iri 20 nguva nezve mechanical nzira;
Laser kuchekakunaka kwakanaka. Kuenzaniswa neoxy-acetylene uye nzira dzekucheka plasma, kucheka kabhoni simbi kune yakanakisa mhando. Iyo inopisa yakakanganiswa nzvimbo yekucheka laser ndeye oxy-acetylene chete.
2.Kushandiswa kwelaser welding tekinoroji mumunda weaerospace
Muindasitiri yezvemuchadenga, zvikamu zvakawanda zvakasungwa ne electron beam, nekuti laser welding haidi kuitwa muvacuum, laser welding iri kushandiswa kutsiva maelectron beam welding.
Kwenguva yakareba, kubatana pakati pezvikamu zvezvimiro zvendege kwave kuri kushandiswa kwekudzokera kumashure riveting tekinoroji, chikonzero chikuru ndechekuti iyo aruminiyamu alloy inoshandiswa muchimiro chendege ndeye kupisa kurapwa kwakasimbiswa aruminiyamu alloy (kureva, yakakwirira simba aruminiyamu alloy), kamwe chete fusion. welding, kupisa kurapwa kusimbisa mhedzisiro icharasika, uye intergranular makatsemuka zvakaoma kudzivisa.
Kugamuchirwa kwelaser welding tekinoroji kunokunda matambudziko akadai uye kunorerutsa zvakanyanya kugadzirwa kweiyo ndege fuselage, kuderedza huremu hwefuselage ne18% uye mutengo ne21.4% ~ 24.3%. Laser welding tekinoroji ndeye shanduko yetekinoroji muindasitiri yekugadzira ndege.
3.Kushandiswa kwelaser drilling tekinoroji mumunda weaerospace
Laser drilling tekinoroji inoshandiswa muindasitiri yezvemuchadenga kuchera makomba pamabhengi emidziyo yemidziyo, mhepo-yakatonhorera turbine blades, nozzles uye combustors. Parizvino, kuchera laser kunogumira kumakomba ekutonhorera ezvimisikidzwa zvejini, nekuti kune microscopic makatsemuka pamusoro pemakomba.
Iyo yekuyedza kudzidza yelaser beam, erekitironi danda, electro chemistry, EDM kuchera, mechanika kudhirowa uye punching inopedzwa nekuongorora kwakadzama. Laser drilling ine mabhenefiti ekuita kwakanaka, kusimba kwakasiyana-siyana, kushanda kwakanyanya uye mutengo wakaderera.
4.Kushandiswa kwelaser surface tekinoroji mumunda weaerospace
Laser cladding chinhu chakakosha pamusoro pekugadzirisa tekinoroji. Mundege, mutengo wezvimedu zveaero-injini wakakwira, saka muzviitiko zvakawanda zvinodhura kugadzirisa zvikamu.
Zvisinei, hutano hwezvikamu zvakagadziriswa hunofanira kuzadzisa zvinodiwa zvekuchengetedza. Semuyenzaniso, kana kukuvara kuchionekwa pamusoro peblade yepropeller yendege, inofanirwa kugadziriswa neimwe tekinoroji yekurapa pamusoro.
Pamusoro pesimba repamusoro uye kuramba kuneta kunodiwa nemapropeller blades, kupikisa kwecorrosion mushure mekugadzirisa kwepamusoro kunofanirwawo kutariswa. Laser cladding tekinoroji inogona kushandiswa kugadzirisa 3D pamusoro peinjini blade.
5.Kushandiswa kwelaser kugadzira tekinoroji mumunda weaerospace
Iko kushandiswa kwelaser yekugadzira yekugadzira tekinoroji mundege inoratidzwa zvakananga mukugadzirwa kwakananga kwetitanium alloy zvimiro zvikamu zvekubhururuka uye nekukurumidza kugadzirisa kwezvikamu zveinjini yendege.
Laser yekugadzira tekinoroji yave imwe yeakakosha matekinoroji ekugadzira ehombe titanium alloy zvimiro zvikamu zvezvombo zvekudzivirira zvemuchadenga nemidziyo. Iyo yechinyakare yekugadzira nzira ine zvipingamupinyi zvemutengo wakakwira, nguva yekugadzirira kwenguva refu yekuforoma mold, huwandu hukuru hwema mechanical processing uye yakaderera zvinhu zvekushandisa.
