Yuav Ua Li Cas Tshawb Xyuas Cov Kev Tiv Thaiv Sab Hauv Hauv 3D Lub Cav Txias Qhov Chaw?

Lub tshuab cua txias tuaj txog saib zoo meej. Dimensions phim cov duab, qhov chaw yog huv si, thiab nws haum rau fixture tsis muaj quab yuam. Nyob rau hauv lub rooj ntev zaum qhov kev ntsuam xyuas tus nqi ntws qis dua li qhov xav tau thiab qhov kub thiab txias nce nrawm dua li qhov lawv yuav tsum tau ua. Tsuas yog tom qab txiav qhov qhib qhov pab pawg pom cov hmoov seem seem thaiv ib nrab ntawm cov channel. External checks yeej tsis ntes tau nws.

Qhov no tshwm sim tsis tu ncua nrog complexHlau 3D Printed Cheebtsam. Ib feem uas zoo nyob rau sab nraud tseem tuaj yeem txwv lossis thaiv cov channel sab hauv. Rau lub cav txias qhov chaw uas nyob ntawm cov kua dej meej, txawm tias ib feem ntawm cov blockages txo cov cua sov hloov mus thiab ua rau muaj kev pheej hmoo ntawm overheating. Phau ntawv qhia no hais txog vim li cas cov ntawv blockages, tsib txoj hauv kev los nrhiav lawv, tsim cov kev xaiv uas ua kom yooj yim rau kev ntxuav, thiab seb yuav nrhiav dab tsi thaum xaiv tus neeg muag khoom.

Laser hmoov txaj fusion tawm cov hmoov tsis muaj hmoov nyob hauv ib qho ntim ntim. Cov hmoov ntawd yuav tsum tau muab tshem tawm tom qab tsim. Thaum cov channel ntev, nkhaus, lossis tsis zoo, kev tshem tawm ua tiav yuav nyuaj.

Trapped hmoov nyob rau hauv ntev los yog nkhaus raws

Hmoov nyob rau hauv cov ntsiab lus qis, nruj khoov, thiab kab rov tav seem. High-muab- cov channel sib piv thiab cov kev hloov pauv ntau yam yog qhov teeb meem feem ntau. Compressed cua thiab vibration feem ntau tshem cov seem yooj yim tab sis cia cov khoom nyob rau hauv qhov nyuaj tshaj plaws - mus rau - mus txog qhov chaw.

Ib nrab Sintered Powder thiab Nto Roughness

Hauv qab-fab qhov chaw feem ntau tuav cov khoom uas tau yaj ib nrab. Cov khoom no ua rau lub ntsej muag roughness-feem ntau 20–50 µm Sa los yog siab dua li ntawm -tsim qhov chaw ntawm daim tawv nqaij-thiab tsim kev txwv hauv zos. Roughness ib leeg nce siab poob thiab txo qis kev ua haujlwm txias.

Txhawb Nqa Residue thiab Dross

Cov channel uas tsis yog tus kheej - kev txhawb nqa tuaj yeem tawm hauv kev txhawb nqa lossis poob qis (cov khoom uas sags rau hauv cov channel). Ob qho tib si tsim cov kev txwv mus tas li uas tus qauv tu tsis tshua tshem tawm tag nrho.

CT cov kev tshawb fawb thiab kev tsim khoom tau lees paub tias cov hmoov seem seem thiab qhov chaw tsis zoo nyob hauv ob qho tib si feem ntau tsis xws luag hauv cov hlau additive manufacturing ntawm cov khoom cua txias.

Tsis muaj ib txoj hauv kev npog txhua qhov xwm txheej. Xaiv raws li qhov nyuaj channel, ib feem tus nqi, thiab qib kev ntseeg siab uas koj xav tau.

Visual thiab borescope soj ntsuam
Ua hauj lwm rau luv luv, ncaj raws nrog meej qhib. Lub borescope tuaj yeem ntes cov blockages loj nyob ze qhov kawg. Nws tsis tuaj yeem pom nyob ib puag ncig kev khoov nruj lossis tob rau hauv cov tes hauj lwm nyuaj, thiab nws feem ntau tsis nco txog qee qhov kev txwv nyob sab hauv.

Air flow test
Kev tshuaj xyuas sai thiab pheej yig. Cua yog dhau los ntawm cov channel ntawm kev tswj lub siab thaum ntsuas tus nqi qis lossis siab poob. Kev sib txawv loj los ntawm qhov xav tau qhov tseem ceeb tshaj qhov teeb meem sai. Nws tsis nrhiav qhov blockage lossis tag nrho cov kev txwv ib feem.

Cov kua dej ntws thiab kev ntsuas siab poob
Ze rau qhov kev ua haujlwm tiag tiag. Coolant los yog dej yog circulated nyob rau hauv tus neeg sawv cev tus nqi thiab siab. Ntsuas qhov poob siab thiab ntws yog muab piv rau cov hom phiaj tsim los yog paub txog - qhov zoo. Txoj kev no ntes tau cov teeb meem ua haujlwm uas qhov kev kuaj pom tsis pom.

CT scanning
Qhov kev ntseeg siab tshaj plaws uas tsis yog -kev xaiv puas tsuaj. Kev lag luam CT tsim kom muaj tag nrho 3D ntim ntawm ib feem thiab qhia cov hmoov seem, phab ntsa - thickness variation, thiab ib nrab blockages nyob qhov twg hauv cov channel. Nws tseem tuaj yeem sib piv qhov ua - ua geometry ncaj qha rau CAD qauv. Rau txoj kev ua kom txias txias, CT tseem yog tus qauv kub.

Qhov hnyav thiab kev kuaj xyuas
Siv tau raws li cov ntaub ntawv pov thawj. Kev npaj txhij txog huab hwm coj tom qab ntxuav tuaj yeem qhia tau tias muaj cov hmoov txhuv nplej siab. Cov kua dej Tracer qee zaum tseem ceeb rau thaj chaw txwv, txawm hais tias cov txiaj ntsig tsis tshua meej dua li CT lossis kev ntsuas txaus.

Kev sib piv ntawm cov txheej txheem tshuaj xyuas

Prototype theem

Hauv SLM 3D Printing Prototyping, pib nrog kev ntsuas huab cua lossis kua dej ntawm txhua thawj kab lus, tom qab ntawd ntxiv CT scanning ntawm cov qauv tseem ceeb. Flow testing sai sai qhia koj seb tus tsim puas ua haujlwm. CT paub meej tias cov channel tau meej meej thiab phim cov duab geometry. Kev ntes cov teeb meem thaum ntxov txuag lub sijhawm rov ua dua.

Me -Batch thiab Production Stage

Teem ib txoj kev npaj ua piv txwv meej. Siab -tus nqi lossis kev nyab xeeb- qhov tseem ceeb feem ntau tau txais 100% kev ntsuas ntws los yog CT. Lwm qhov chaw siv cov lej suav nrog cov ntaub ntawv tag nrho. Khaws cov ntaub ntawv ntawm tus nqi ntws, qhov poob siab, thiab CT cov txiaj ntsig kom txhua pawg tseem tuaj yeem taug qab.

Cov teeb meem thaiv feem ntau pib hauv theem tsim. Cov kev cai coj ua uas txo kev pheej hmoo:

Khaws cov kab hluav taws xob ntau lawm ntawm 1 hli lossis loj dua tshwj tsis yog kev ntxuav thiab tshuaj xyuas cov txheej txheem tau ua tiav rau qhov me me.

Siv tus kheej-txhawb tus ntoo khaub lig- ntu (teardrop, pob zeb diamond, lossis elliptical) nrog cov kaum sab xis ntawm 45℃lossis steeper.

Zam kev khoov ntse; siv dav dav radii qhov twg los tau.

Ntxiv cov hmoov tshwj xeeb- qhov khiav tawm lossis qhov qhib ib ntus uas tuaj yeem kaw tom qab ntxuav.

Orient lub ntsiab channel kev taw qhia los pab hmoov ntws thaum thiab tom qab tsim.

Tsim cov ntsiab lus nkag mus tau yooj yim thiab tawm yog li kev ntsuas ntws thiab kev kuaj borescope tseem siv tau.

Cov kev xaiv no txo ​​qis cov hmoov seem seem thiab ua rau ob qho tib si ntxuav thiab tshuaj xyuas ntau dua.

Thaum cov khoom ua kom txias nrog cov kev sib haum xeeb tuaj txog rau kev tsim khoom, cov txheej txheem pib nrog kev tshuaj xyuas tsim tsom rau kev tshem tawm cov hmoov thiab tshuaj xyuas. Channel geometry raug tshuaj xyuas rau tus kheej - txhawb nqa nta, kev khiav tawm, thiab tsim kev taw qhia. Tom qab luam ntawv, ntau - kauj ruam tu ib ntus- kev vibration, compressed cua, thiab lub hom phiaj flushing - yog siv. Thawj cov kab lus tom qab ntawd mus dhau ntawm kev ntsuas ntws ua raws li CT scanning kom paub meej tias qhov tseeb thiab qhov tseeb. Txhua cov hmoov seem lossis geometric sib txawv tau sau tseg thiab siv los kho cov txheej txheem ua ntej ntau lawm tso tawm. Kev sib xyaw cov tswv yim tsim, tswj kev ntxuav, thiab kev ntsuas qhov ntsuas ntsuas tsis tu ncua yuav txo tau txoj hauv kev thaiv cov channel mus txog tus neeg siv khoom.

Tsis yog txhua tus neeg muag khoom tuaj yeem xa thiab txheeb xyuas cov kev huv huv hauv. Thaum ntsuam xyuas lub tuam txhab hlau 3D luam ntawv lossis SLM 3D tshuab luam ntawv, nug cov lus nug no:

Puas yog lawv ua CT scan lossis ntsuas ntsuas qhov sib npaug ntawm cov channel sab hauv?

Puas yog cov dej ntws los yog siab- cov txiaj ntsig kev ntsuas poob tau muab nrog cov khoom?

Lawv puas tuaj yeem tuav ob tus qauv thiab me me -batch lossis cov khoom lag luam wholesale hlau 3D luam tawm nrog cov ntaub ntawv tshuaj xyuas zoo ib yam?

Lawv puas muab cov tswv yim tsim qauv ntawm kev ua kom huv huv ntawm cov channel tsis yog tsuas yog sau cov ntawv luam tawm?

Puas yog kev sib txuas lus meej meej thiab raws sijhawm thaum muaj teeb meem tshwm sim?

Lub peev xwm kev cai hlau 3D luam tawm cov khoom lag luam kho cov hmoov tshem tawm thiab kev txheeb xyuas channel raws li cov txheej txheem tseem ceeb. Nrhiav cov pov thawj ntawm kev tswj xyuas cov txheej txheem ntxuav thiab cov ntaub ntawv muaj peev xwm soj ntsuam es tsis yog kev lag luam thov ib leeg.

Yog tias koj tab tom tsim lossis tsim cov khoom cua txias nrog cov channel hauv, xa koj cov ntaub ntawv STEP rau kev tsim qauv pub dawb-rau- kev tsim khoom thiab tshuaj xyuas. Kev tshuaj xyuas yuav chij hmoov- tshem tawm cov kev pheej hmoo, qhia txog kev hloov pauv ntawm cov duab thiab cov duab, thiab qhia txog cov phiaj xwm kev tshuaj xyuas zoo rau ob qho tib si qauv thiab cov ntim ntau lawm. Cov kev huv huv sab hauv yog qhov tshwm sim ntawm kev tsim qauv, kev tswj cov txheej txheem, thiab kev txheeb xyuas - tsis yog qhov tshwm sim tsis siv neeg ntawm hlau 3D luam ntawv.
