Thaum cov engineers aerospace xav tau cov peev txheej pov tseg uas tuav ± 0.05 mm kam rau ua raws li 300 MPa hydraulic loads, lawv tsis khom rau cov hom phiaj dav dav. Lawv nrhiav ib aero hlau peev casting Hoobkas nrog cov ntaub ntawv sau tseg metallurgical tswj, xoom-batch drift hauv AMS 5387 cobalt alloy, thiab CNC-machined nta raws li GD&T callouts-tsis yog kos duab. Qhov ntawd yog qhov uas precision nres ua qhov kev qhia tshwj xeeb thiab dhau los ua cov txheej txheem rov ua dua.
Peb tau pom ntau qhov chaw nres tsheb thaum castings dhau qhov ntsuas qhov ntsuas tab sis ua tsis tiav thermal cycling ntawm -55 ° C txog + 120 ° C vim tias cov qauv nplej tsis tau lees paub ua ntej-kub-kho. Los yog thaum lub twj tso kua mis lub tsev tawg tom qab 420 teev ntawm kev ua haujlwm tas mus li - tsis yog los ntawm kev tsim qhov tsis zoo, tab sis los ntawm micro-porosity ze rau thaj av siab-cuam tshuam uas tau dhau los ntawm kev kuaj pom. Cov no tsis yog rooj plaub ntug. Lawv yog qhov txawv ntawm "kev xa khoom" thiab "kev tsim nyog dav hlau." Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua tus cobalt-nickel peev casting pib nrog ntawv pov thawj T800 alloy billets, traceable mus rau cov xov tooj cua sov, nrog rau cov ntaub ntawv spectrographic cross-checked tiv thaiv ASTM E1096 ua ntej melting.
Lawv qhov chaw ua raws ISO-raws li Qingdao tsis khiav peev casting raws li ib tug standalone kab-nws integrates nws nruj nreem nrog tsib-axis machining, kev daws annealing, thiab tsis-destructive xeem. Piv txwv li: AMS 5387 nozzle tsis yog cam khwb cia, ces machined, ces tshuaj xyuas. Nws yog cam khwb cia nrog 0.3 hli machining nyiaj pub rau ntawm qhov tseem ceeb sealing nto; tom qab cua sov-kho hauv lub tshuab nqus tsev vacuum calibrated txhua hnub; tiav-machined siv Renishaw-probed setups uas nws pib-compensate rau thermal loj hlob; thiab tshuaj xyuas nrog Zeiss CMMs khiav ASME B89.4.10-ua raws li niaj hnub - ntsuas tsis yog qhov loj me xwb, tab sis tsim kev ua yuam kev, kev ncaj ncees ntawm qhov chaw, thiab cov hardness gradients hauv zos. Qhov kev sib koom ua ke ntsug no tshem tawm cov kev sib koom tes uas qhov kev kam rau siab sib sau. Lub piston twj tso kua mis lub tog raj kheej lub tsev tuaj txog ntawm QA zaum kawg nrog cov keeb kwm tag nrho-tsis yog daim ntawv hla / tsis tau.
Qee tus yuav sib cav hais tias xuab zeb casting muab cov nqi zoo dua rau cov khoom siv loj loj. Tab sis rau nyias-walled, high-aspect-ratio aerospace manifolds-tshwj xeeb tshaj yog cov uas yuav tsum tau nyob rau hauv lub txias channel los yog conformal kua txoj kev-kev nqis peev casting tseem unmatched. QIANGSENYUAN ua pov thawj qhov no los ntawm niaj hnub tsim cov hlau tsis muaj steel hlau nrog 1.2 hli phab ntsa tuab, 0.8 hli sab hauv radii, thiab nto tiav nyob rau hauv Ra 1.6 µm-raws li xa, tsis yog tom qab polished. Lawv cov txheej txheem ceramic siv zircon-raws li slurries thiab fused silica stucco, ua kom muaj kev kub ntxhov uas khaws cov ntsiab lus zoo yam tsis muaj micro-cracking. Thiab tsis zoo li cov khw muag khoom sab nrauv lub tsev, lawv lub plhaub tag nrho ua haujlwm nyob rau hauv cov av noo thiab kub tswj (± 2 ° C, 45-55% RH), vim hais tias txawm tias me me noo variation hloov plhaub permeability - thiab hloov cov hlau ntws nrawm thaum lub sij hawm nchuav.
Dab tsi ua rau lawv sib nrug tsis yog kev muaj peev xwm xwb - nws yog qhov lawv siv nws li cas. Thaum lub European hydraulics OEM xav tau 27 lub cev valve lub cev hauv T800 cobalt alloy, lawv tsis yog hais raws li 3D qauv ntim. Cov kws ua haujlwm tau tshuaj xyuas GD&T cov lus piav qhia, qhia txog qhov muaj peev xwm hloov pauv qhov kev pheej hmoo ntawm 0.15 mm datum feature, qhia txog kev hloov kho me me kom tsis txhob muaj kev sib tsoo, thiab muab cov ntaub ntawv soj ntsuam cov ntaub ntawv uas qhia lub zog tensile ≥1,380 MPa ntawm 650 ° C — txheeb xyuas ib AMS 2269. Cov hom kev sib koom ua ke 40%. Lawv cov txheej txheem kev npaj ntshiv taug qab txhua qhov kev txiav txim tawm tsam lub sijhawm ua haujlwm - tsis yog kwv yees cov sijhawm ua haujlwm - yog li nruab nrab-ntim khiav (50-300 pcs) nkoj hauv 12 hnub ua haujlwm, tsis tu ncua. Tsis muaj "txoj cai ntawm cov khoom muaj nyob" clauses. Tsis xav tsis thoob NRE nqi rau thawj tsab ntawv pom zoo.
Yog hais tias koj tab tom nrhiav precision aerospace Cheebtsam uas tsis ua hauj lwm txhais tau hais tias lub kaw lus downtime - los yog phem tshaj - koj xav tau ntau tshaj casting peev xwm. Koj xav tau kev qhuab qhia metallurgical, kev soj ntsuam nruj uas phim koj cov kev xav tau ua haujlwm, thiab kev tsim kho engineering los ntawm kev kos duab los ntawm kev ntim khoom zaum kawg. Ib aero hlau peev casting Hoobkas zoo li QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. muab qhov ntawd-tsis yog cov lus lag luam, tab sis raws li cov ntaub ntawv pov thawj, cov ntawv pov thawj tshwj xeeb, thiab cov khoom uas ua tau zoo ib yam thoob plaws ntau ntau lawm. Cov kauj ruam tom ntej yog tsis sib piv cov nqe lus. Nws tab tom sib koom koj pob GD&T thiab nug: "Qhov twg koj yuav cia siab tias thawj qhov kev pheej hmoo - thiab koj yuav txo nws li cas?" Qhov kev sib tham ntawd cais cov neeg xa khoom los ntawm cov neeg koom tes.
