Activating lub innovation saw thiab industrial saw

Txawm hais tias qhov kev loj hlob sai ntawm kuv lub teb chaws kev lag luam additive manufacturing kev lag luam, kev lag luam tseem nyob rau theem pib ntawm txoj kev loj hlob thiab tseem muaj cov yam ntxwv ntawm cov nplai qis. Txawm li cas los xij, qhov tsis muaj kev paub txog thev naus laus zis, kev siv nyiaj siab, thiab daim ntawv thov nqaim tau ua rau kev lag luam tag nrho nyob rau hauv lub xeev ntawm "me me, tawg thiab tsis muaj zog". Txawm hais tias muaj ntau lub tuam txhab tau pib taug kev hauv thaj chaw ntawm kev tsim khoom ntxiv, tsis muaj cov tuam txhab ua lag luam uas tau tsav, qhov ntsuas ntawm kev lag luam me me. Tus kws tshaj lij Lu Bingheng tau hais ncaj qha tias yog ib qho ntawm cov thev naus laus zis tseem ceeb ntawm kev hloov pauv kev lag luam yav tom ntej, kev tsim cov khoom siv ntxiv yuav tsum tau nrawm dua, vim tias 3D tshuab luam ntawv yog nyob rau lub sijhawm ntawm kev siv tshuab, lub sijhawm pib ntawm kev lag luam, thiab lub sijhawm "staking" ntawm cov lag luam. Qhov kev xav tau ntawm kev lag luam loj tuaj yeem tsav txoj kev loj hlob ntawm kev siv tshuab thiab cov cuab yeej siv, uas yuav tsum tau tiv thaiv thiab siv tag nrho los coj thiab txhawb peb cov khoom tsim khoom.

Tam sim no cov cuab yeej tuaj txawv teb chaws yog aggressively "sib ntaus" hauv Suav lag luam. Rau cov khoom siv hlau luam ntawv, cov teb chaws txawv teb chaws siv bundled muag khoom, software, khoom siv, thiab cov txheej txheem. Cov tuam txhab suav teb yuav tsum tsim cov thev naus laus zis tseem ceeb thiab cov thev naus laus zis qub los tsim lawv tus kheej kev tsim kho tshiab thiab kev lag luam chains.

Kev lag luam sab hauv tau hais tias tam sim no kev lag luam hauv tsev 3D luam ntawv, qib ntawm kev tshawb fawb thiab kev tsim kho tshuab tau siv tag nrho rau kev lag luam, thiab ntau yam kev ua tiav tsuas yog nyob rau hauv chav kuaj. Cov laj thawj tseem ceeb ntawm qhov teeb meem no yog: ua ntej, vim muaj ntau yam qauv, kev nkag mus rau Cov kev tsim nyog tsis zoo tag nrho, thiab muaj qhov tsis pom kev rau kev nkag; Thib ob, cov tsev kawm tshawb fawb thiab cov tuam txhab lag luam tsis muaj qhov cuam tshuam loj, lawv nyob hauv lub xeev ntawm kev sib ntaus sib tua ib leeg, lawv tsis muaj cai hais lus hauv kev lag luam kev sib tham, thiab lawv muaj qhov tsis zoo; Kev lag luam tshiab tsis to taub, thiab muaj kev sib tw lossis kev nkag siab yuam kev, ua rau qeeb qeeb ntawm kev siv tshuab.

Txoj Kev Loj Hlob Ntawm Cov Khoom Siv Atomization Pulverizing Yav Tom Ntej

Tseem muaj ntau qhov tsis txaus ntseeg hauv kev nkag siab ntawm 3D tshuab luam ntawv hauv txhua yam ntawm Tuam Tshoj txoj kev lag luam tsim khoom. Judging los ntawm qhov tseeb txoj kev loj hlob qhov teeb meem, txog tam sim no 3D luam ntawv tsis tau tiav mature industrialization, los ntawm cov khoom mus rau cov khoom mus rau cov kev pab cuam tseem nyob rau hauv lub "advanced khoom ua si" theem. Txawm li cas los xij, los ntawm tsoomfwv mus rau cov tuam txhab lag luam hauv Suav teb, kev txhim kho kev cia siab ntawm 3D luam ntawv thev naus laus zis feem ntau tau lees paub, thiab tsoomfwv thiab tib neeg feem ntau them nyiaj rau qhov cuam tshuam rau yav tom ntej 3D luam ntawv hlau atomization pulverizing cov cuab yeej siv tshuab ntawm kuv lub teb chaws cov khoom lag luam uas twb muaj lawm, kev lag luam, thiab tsim qauv.

Raws li cov ntaub ntawv tshawb fawb, tam sim no, kuv lub teb chaws qhov kev thov rau 3D luam ntawv thev naus laus zis tsis yog tsom rau cov cuab yeej siv, tab sis tau xav txog ntau yam ntawm 3D luam ntawv consumables thiab qhov kev thov rau lub koom haum ua cov kev pabcuam. Cov neeg siv khoom lag luam yog lub zog tseem ceeb hauv kev yuav khoom 3D luam ntawv hauv kuv lub tebchaws. Cov khoom siv uas lawv yuav yog tsuas yog siv hauv aviation, aerospace, cov khoom siv hluav taws xob, kev thauj mus los, kev tsim, kev coj noj coj ua thiab lwm yam kev lag luam. Tam sim no, lub peev xwm nruab ntawm 3D tshuab luam ntawv hauv Suav lag luam yog li 500, thiab kev loj hlob txhua xyoo yog li 60%. Txawm li cas los xij, kev lag luam tam sim no tsuas yog kwv yees li 100 lab yuan ib xyoo. Lub peev xwm thov rau R & D thiab tsim cov ntaub ntawv 3D luam ntawv tau mus txog ze li ntawm 1 billion yuan ib xyoos twg. Nrog rau qhov nrov thiab kev nce qib ntawm cov cuab yeej siv tshuab, qhov ntsuas yuav loj hlob sai. Nyob rau tib lub sijhawm, 3D luam ntawv ntsig txog kev pabcuam kev ua haujlwm yog nrov heev, thiab ntau tus neeg ua haujlwm 3D luam ntawv Lub tuam txhab cov cuab yeej siv tau zoo heev hauv cov txheej txheem laser sintering thiab cov khoom siv, thiab tuaj yeem muab kev pabcuam sab nraud. Txij li thaum tus nqi ntawm ib qho khoom siv feem ntau yog ntau tshaj 5 lab yuan, qhov kev lees paub ntawm kev ua lag luam tsis siab, tab sis lub koom haum ua cov kev pabcuam yog nrov heev.

Feem ntau ntawm cov ntaub ntawv siv nyob rau hauv kuv lub teb chaws 3D luam ntawv hlau atomization pulverizing khoom yog muab ncaj qha los ntawm prototyping sai manufacturers, thiab cov neeg thib peb ntawm cov khoom siv tseem tsis tau muab coj los siv, uas ua rau cov khoom kim heev. Nyob rau tib lub sijhawm, tsis muaj kev tshawb fawb txog kev npaj hmoov rau 3D luam ntawv hauv Suav teb, thiab muaj cov kev cai nruj me ntsis ntawm particle loj faib thiab cov ntsiab lus oxygen. Qee chav nyob siv cov tshuaj tsuag cov pa siv xwb, uas muaj ntau yam siv tsis tau.

Kev txhim kho thiab tsim cov khoom siv ntau yam yog tus yuam sij rau kev txhim kho thev naus laus zis. Kev daws cov teeb meem kev ua tau zoo thiab cov nqi ntawm cov ntaub ntawv yuav zoo dua los txhawb kev txhim kho sai prototyping thev naus laus zis hauv Suav teb. Tam sim no, feem ntau ntawm cov ntaub ntawv siv nyob rau hauv kuv lub teb chaws 3D luam ntawv sai prototyping tshuab yuav tsum tau imported los ntawm txawv teb chaws, los yog cov khoom manufacturers tau nqis peev ntau lub zog thiab nyiaj txiag los tsim lawv, uas yog kim, ua rau cov nqi ntau lawm, thaum. cov khoom siv hauv tsev siv nyob rau hauv lub tshuab no muaj lub zog tsawg thiab qhov tseeb. . Localization ntawm 3D luam ntawv cov ntaub ntawv yog qhov tseem ceeb.

Titanium thiab titanium alloy hmoov los yog npib tsib xee-raws li thiab cobalt-based superalloy hmoov uas tsis tshua muaj oxygen cov ntsiab lus, nplua particle loj thiab siab sphericity yuav tsum tau. Cov hmoov particle loj yog feem ntau -500 mesh, cov ntsiab lus oxygen yuav tsum qis dua 0.1%, thiab cov particle loj yog uniform Tam sim no, high-end alloy hmoov thiab cov cuab yeej tsim khoom tseem tsuas yog cia siab rau imports. Hauv cov teb chaws txawv teb chaws, cov khoom siv raw thiab cov khoom siv feem ntau tau ntim thiab muag kom tau txais txiaj ntsig ntau. Noj cov hmoov nickel raws li piv txwv, tus nqi ntawm cov khoom siv raw yog kwv yees li 200 yuan / kg, tus nqi ntawm cov khoom siv hauv tsev feem ntau yog 300-400 yuan / kg, thiab tus nqi ntawm cov hmoov tuaj txawv teb chaws feem ntau ntau dua 800 yuan / kg.

Piv txwv li, kev cuam tshuam thiab kev hloov pauv ntawm cov hmoov muaj pes tsawg leeg, suav nrog thiab lub cev muaj zog ntawm cov cuab yeej muaj feem xyuam ntawm 3D luam ntawv hlau atomization hmoov milling khoom. Yog li ntawd, nyob rau hauv qhov kev pom ntawm kev siv cov ntsiab lus ntawm cov pa oxygen tsawg thiab cov hmoov zoo me me, nws tseem yuav tsum tau ua cov haujlwm tshawb fawb xws li kev tsim qauv ntawm titanium thiab titanium alloy hmoov, roj atomization hmoov milling tshuab ntawm cov hmoov me me hmoov, thiab kev cuam tshuam ntawm hmoov yam ntxwv ntawm cov khoom ua tau zoo. Vim muaj kev txwv ntawm kev siv tshuab milling hauv Suav teb, nws yog ib qho nyuaj rau kev npaj cov hmoov nplej nplua nuj nyob rau tam sim no, cov hmoov nplej tau qis, thiab cov ntsiab lus ntawm oxygen thiab lwm yam impurities yog siab. Thaum lub sij hawm siv cov txheej txheem, cov hmoov melting lub xeev yog nquag mus rau unevenness, ua rau cov ntsiab lus siab ntawm oxide inclusions thiab denser khoom nyob rau hauv cov khoom. Cov teeb meem tseem ceeb ntawm cov hmoov hlau hauv tsev yog nyob rau hauv cov khoom zoo thiab kev ruaj ntseg batch, xws li: ① ruaj khov ntawm cov khoom siv hmoov (tus naj npawb ntawm cov khoom sib xyaw, cov khoom sib xws); ② hmoov lub cev ruaj khov ntawm kev ua tau zoo (particle loj faib, hmoov morphology, fluidity, xoob ratio, thiab lwm yam); ③ teeb meem ntawm yield (tsawg tawm los ntawm hmoov nyob rau hauv nqaim particle loj seem), thiab lwm yam.
