一, Core ncej- txheej txheem thev naus laus zis thiab rhuav tshem nws siv sijhawm ntev npaum li cas
Muaj tsib theem tseem ceeb hauv kev tshaj tawm -kev ua cov hlau 3D luam ntawv: tshem cov hmoov, txo kev ntxhov siab, cua sov, machining, thiab kho qhov chaw. Tus nqi ntawm lub sij hawm txhua kauj ruam yog feem ntau khi rau txoj kev xaiv.
1. Tshem tawm cov hmoov thiab sib cais cov khoom: yooj yim tab sis siv sij hawm ntau heev
Tom qab cov ntawv hlau tau tsim nyob rau hauv cov hmoov txaj fusion system, cov hmoov faus yuav tsum tau muab tshem tawm thiab sieved yog li nws yuav siv tau dua. Kev ntxuav me me ntawm tes yuav siv sijhawm 1 mus rau 2 teev, qhov kev tu cov khoom loj xws li lub tshuab cav cav yuav siv li 3 mus rau 5 teev thiab xav tau cov cuab yeej tshwj xeeb nqus tsev vacuum thiab tshuaj ntsuam kev co. Hlau hluav taws xob tso tawm txiav yog txoj hauv kev zoo tshaj plaws rau kev sib cais, txawm li cas los xij nws tuaj yeem siv li 4 mus rau 8 teev rau ib daim los txiav thiab tso cov khoom sib txuam xws li cov dej ntws sab hauv. Band pom txiav yog ceev (10 mus rau 30 feeb ib thooj), tab sis nws tsuas yog ua haujlwm rau cov qauv geometric yooj yim thiab tuaj yeem ua rau cov khoom siv tawv tawv.
2. Kev txo cov kev ntxhov siab thiab kev kho cua sov: tseem ceeb rau kev ua kom paub tseeb
Yog tias qhov kev ntxhov siab hauv cov txheej hlau los ntawm txheej tsis tau txo qis, nws yuav ua rau cov khoom khoov lossis tawg. Ib txoj hauv kev zoo tshaj plaws yog siv lub tshuab nqus tsev vacuum rau anneal titanium alloy qhov chaw. Lawv yuav tsum tau khaws cia ntawm 650℃rau 4 teev, tom qab ntawd txias rau chav sov li 6-8 teev, rau tag nrho lub sijhawm voj voog ntau dua 10 teev. Siab - qhov kub thiab txias alloy qhov chaw, ntawm qhov tod tes, yuav tsum tau rhaub rau 1200 degree, tuav rau 6 teev, thiab txias tshaj 12 teev. Kub isostatic nias (HIP) tuaj yeem tshem tawm ntawm ob qhov pores thiab kev ntxhov siab tib lub sijhawm, tab sis cov cuab yeej siv kim, thiab txhua lub voj voog ua haujlwm (uas suav nrog kev nce thiab txo qhov kub) yuav siv sijhawm 8 mus rau 16 teev.
3. Machining thiab kev kho deg: ob lub hom phiaj ntawm qhov tseeb thiab muaj txiaj ntsig zoo
Nws tuaj yeem siv sijhawm li 20 mus rau 40 teev kom ua tiav cov tshuab nyuaj xws li turbine blade flow channels siv tsib -axis linkage machining centre. Nws tuaj yeem siv sijhawm li 5 mus rau 10 xuab moos ntxiv rau cov txheej txheem xws li xov qhov thiab qhov sib txuas. Sandblasting yuav sai sai ua kom lub ntsej muag smoother (Ra tsawg dua lossis sib npaug li 3.2 μ m), thiab nws tsuas yog siv 0.5-2 teev rau ib daim. Tshuaj polishing tuaj yeem ua rau saum npoo zoo li daim iav (Ra Tsawg dua lossis sib npaug ntawm 0.2 μ m), tab sis nws yuav siv sijhawm 12 mus rau 24 teev thiab ob peb kauj ruam (tshem cov roj, ntxuav nrog kua qaub, thiab passivation). Kev sib xyaw xim, kev sim, thiab kev ntsuas tuab yog txhua yam xav tau rau anodising (aluminium alloy) lossis passivation (stainless steel) thiab lwm yam kev kho los tiv thaiv -corrosion. Cov txheej txheem no siv sijhawm 1 txog 3 hnub rau ib yam khoom.
2, Kev lag luam piv txwv: ntau yam xwm txheej muaj ntau lub sijhawm sib txawv
1. Nyob rau hauv lub aerospace teb, ncua mus los ntawm kev ua tau zoo heev.
SLM thev naus laus zis yog siv los luam cov thav duab ntawm cov roj tank rau lub tshuab foob pob hluav taws tshwj xeeb. Kev tshaj tawm - txheej txheem txheej txheem siv sijhawm 94 teev (kwv yees li 4 hnub) thiab koom nrog kev kho HIP (16 teev), CNC machining (30 teev), thiab anodising (48 teev). Nws qhov feem pua siab yog vim qhov xwm txheej hnyav muaj cov qauv nruj heev rau lub neej qaug zog (uas txhais tau hais tias HIP xav tau 300% zoo dua) thiab kev ncaj ncees ntawm qhov chaw (uas txhais tau hais tias kev tshuaj ntsev ntsev yuav tsum tau ua ntau tshaj 1000 teev).
2. Kev kho mob cog qoob loo: biocompatibility yog qhov tseem ceeb tshaj plaws
Kev tshaj tawm- txheej txheem ua tiav rau kev cog cov titanium alloy hip sib koom ua ke yuav siv sijhawm tag nrho 44 teev (kwv yees 2 hnub). Nws suav nrog lub tshuab nqus tsev annealing (12 teev), polishing (8 teev), thiab sterile packing (24 teev). Txawm hais tias lub sij hawm luv luv, qhov roughness ntawm qhov chaw yuav tsum tau nruj me ntsis tswj (Ra <0.1 μ m) kom txo cov pob txha cov ntaub so ntswg kev nyuaj siab shielding cuam tshuam. Kev kuaj Biocompatibility (ISO 10993 tus qauv) kuj tseem xav tau los ua kom lub voj voog ntev dua.
3. Nyob rau hauv lub ntiaj teb no ntawm cov neeg siv khoom siv hluav taws xob, kev tsim khoom loj txo qis rau lub sijhawm nws siv los ua ib yam khoom.
Siv BJ thev naus laus zis, folding screen xov tooj ntawm tes pob khawm scroll yog luam tawm. Kev tshaj tawm- cov kauj ruam ua tiav yuav siv sijhawm li 13 teev: kev kho cua sov (8 teev), sandblasting (1 teev), thiab txheej txheej (4 teev). Vim muaj ntau lawm (ntau tshaj 10,000 daim ib batch), automated ntau lawm kab (xws li robotic polishing) tau txiav lub sij hawm nws yuav siv sij hawm los muab txhua daim rau tsawg tshaj li ib nrab ib teev, uas yog luv luv dua nyob rau hauv lub aerospace kev lag luam.
3, Technology Trend: Intelligence thiab Automation Shorten Cycle
1. Cov txheej txheem kev tsim kho tshiab txo qis qhov xav tau rau kev tshaj tawm - ua tiav
Cov tshuab luam ntawv tsis muaj kev saib xyuas (xws li thaj chaw luam ntawv thiab ob npaug - sab hmoov txheej) tuaj yeem txiav cov qauv kev txhawb nqa los ntawm 40% mus rau 60%, uas txiav lub sijhawm nws siv los tshem tawm cov kev txhawb nqa los ntawm ob peb teev mus rau 0.5 mus rau 1 teev. Hauv qhov chaw kho cua sov thev naus laus zis sib txuas cov txheej txheem annealing nrog cov cuab yeej luam ntawv, uas txuag lub sijhawm rau kev hloov mus rau ib feem thiab lub cub tawg thiab ua kom lub voj voog luv dua li 30%.
2. Cov khoom siv kho dua tshiab ua rau kev ua haujlwm sai dua
Lub AI-powered polishing neeg hlau tuaj yeem hloov kho nws cov kev ua raws li kev tswj xyuas quab yuam, txiav lub sijhawm nws siv los txhuam ib qho ntawm 2 teev mus rau 0.5 teev. Lub tsib -axis linkage machining center muaj qhov kev tshawb nrhiav hauv online uas tuaj yeem kho cov cuab yeej hauv lub sijhawm tiag tiag, txo tus nqi rov ua haujlwm thiab nce kev ua haujlwm ntawm kev ua haujlwm nyuaj ntawm qhov chaw los ntawm 50%.
3. Cov txheej txheem ntawm kev ua hauj lwm ua ke los txhim kho kev lag luam saw
Printing heat treatment machining integrated equipment, like EOS's M400-4 system from Germany, combines tag nrho cov kauj ruam tom qab luam ntawv rau hauv ib lub platform. Qhov no txo qis rau lub sij hawm nws yuav siv sij hawm los mus thiab clamp qhov chaw thiab shortens ntau lawm voj voog los ntawm 40%. Cov huab-raws li txheej txheem database siv AI algorithms los qhia txog kev sib xyaw ua ke zoo tshaj plaws, uas txo qis lub sijhawm nws yuav siv los ua cov kev daws teeb meem tom qab rau qhov tshiab ntawm hnub mus rau teev.
