Cov ntaub ntawv tau zoo heev ntawm 3D loj titanium alloy txoj hauv kev
Tom qab ntau tshaj 200 teev kev ua hauj lwm tas mus li, ib qho loj titanium alloy complex uas nyob ze rau ntawm cov kev txwv ntawm qhov chaw ntawm cov cuab yeej tau tsis ntev los no tau prototyped nyob rau hauv Additive Raug Chaw ntawm Kunming University of Science thiab Technology. Qhov no kuj yog qhov loj tshaj plaws tib titanium alloy complex uas tau raug tsim tawm hnub tim uas siv laser xim melting.
Laser selective melting yog ib hom hlau uas luam tawm 3D hlau. Nws siv cov hluav taws xob laser los ua cov luam tawm ntawm cov hmoov pav los ntawm cov ntaub ntawv ntawm cov khoom sib cais ntawm cov seem, kom cov hmoov hlau yaj thiab yaj kis los ntawm taw tes, thiab cov khoom hlau yog ncaj qha tuaj. Cov khoom hlau uas ua los ntawm cov qauv no muaj cov khoom vaj khoom tsev zoo, zoo siab thiab qhov zoo tshaj plaws, thiab yog cov kev tshawb fawb kub ntawm cov hlau hlau luam tawm. Lub titanium alloy txoj ua los ntawm xibfwb Li Zhenhua tus pab pawg neeg muaj kev loj hlob ntawm 250 × 250 × 257 hli thiab tag nrho ntawm qhov chaw thiab kev txhawb nqa tshaj 21 kg.
Raws li cov lus ceeb toom, titanium alloy muaj cov khoom sib xyaw zoo thiab kev sib zog tiv thaiv, thiab dav siv hauv aerospace, tshuaj, kev kho mob thiab lwm yam. Nyob rau hauv cov txheej txheem ntawm hlau laser 3D printing, siab residual kev nyuab siab yog generated. Cov teeb meem ntawm kev ntxhov siab deformation thiab tawg thaum lub sij hawm tsim ntawm qhov sib txawv qhov chaw feem ntau yeej yog qhov nyuaj tshaj rau cov hlau 3D luam tawm. Cov teeb meem no muaj ntau dua hauv cov titanium hlau laser 3D luam ntawv. protruding. Xibfwb Li Zhenhua thiab nws pab pawg ua haujlwm ntau yam ua haujlwm hauv cov hmoov thiab kev tswjhwm, kev tivthaiv kabmob thiab kev ua haujlwm zoo, kev txhawb tsim thiab kev nyuab siab, kev saib xyuas lub sijhawm, thiab lwm yam, thiab thaum kawg tau txiav txim siab rau kev xeem ntawv, loj txoj titanium alloy qhov chaw. Tseem ceeb kev paub.
Lub xyoo dhau los, Kunming University of Science thiab Technology Additive Manufacturing Centre tau ua tiav zoo hauv 3D kev tshawb fawb txog kev lag luam hauv kev ua ub ua no ntawm cov aerospace, kev kho mob, thiab pwm. Tam sim no, ntau tshaj 5,700 tus menyuam kawm ntawv nkag mus rau qhov chaw tsim khoom txhua lub xyoo los kawm thiab ua cov haujlwm tshiab; ntau tshaj li 50 tus kws tshaj lij thiab cov kws tshaj lij thiab cov kws qhia ntawv thiab cov xib fwb tau koom nrog kev tshawb fawb ntawm qhov chaw.
