Thaum cov kws tshaj lij qhia cov xuab zeb casting rau cov khoom siv hlau zoo-tshwj xeeb hauv cov tshuab hydraulic, cov khoom siv roj thiab roj, lossis cov twj tso kua mis hnyav-lawv tsis yog xaiv cov txheej txheem xwb. Lawv tab tom xaiv tus khub uas nkag siab tias cov qauv nplej cuam tshuam li cas rau lub neej qaug zog, yuav ua li cas pwm compaction cuam tshuam qhov kev rov ua dua, thiab yog vim li cas 0.15 hli kam rau ntawm lub tsev cobalt-alloy lub tog raj kheej tsis yog qhov kev thov - nws yog qhov yuav tsum tau ua haujlwm tsis sib tham. Qhov ntawd yog qhov kev paub tiag tiag hauv ntiaj teb cais cov neeg xa khoom muaj peev xwm los ntawm qhov tseeb xuab zeb casting foundry Hoobkas cov neeg koom tes.
Vim li cas Sand Casting tseem yeej rau Lub Hom Phiaj-Critical Industrial Cheebtsam
Qee qhov xav tias xuab zeb casting tsuas yog siv rau cov ntaub ntawv qub. Tab sis peb tau pom nws xa rov tuaj yeem ua tiav qhov twg lwm cov txheej txheem ua tsis tiav: cov hlau loj loj uas xav tau thermal poob siab tsis kam hauv cov twj tso kua mis; steel vaj tse nrog cov cua txias sab hauv tsis yooj yim rau tshuab tom qab nrum; cov khoom siv stainless hlau xav tau lub zog isotropic hla ntu tuab. Qhov tseem ceeb yog kev tswj - tsis yog tshaj qhov kub thiab txias lub sij hawm shakeout, tab sis dhau ntawm tag nrho cov saw: ntsuab xuab zeb sib xws, core print alignment, gating design for laminar flow, thiab post-cast stress relief cycles verified by strain gauge mapping.
Hauv ib txoj haujlwm tsis ntev los no, European OEM xav tau 42 lub siab lub cev hauv ASTM A351 CF8M. Lawv cov neeg muag khoom ua ntej tsis tau GD&T callouts ntawm peb lub qhov flange mounting-ua rau kev cuam tshuam los ntawm kev sib dhos hauv qhov kev sim zaum kawg. Peb ntes nws thaum lub sij hawm kos duab validation, kho lub cope qauv ntawm lub kaum sab xis ntawm 0.8 °, thiab ntxiv ib tug thib ob pwm alignment tus pin. Qhov tshwm sim: xoom rework hla 120 units. Qhov kev cuam tshuam no tsis tuaj yeem ua tsis tau yog tias tsis muaj kev sib koom ua ke ntsug tag nrho - los ntawm kev sib xyaw xuab zeb mus rau CNC ua tiav kev ua haujlwm ntawm tib pem teb.
Qhov twg Cov Kws Paub Txog Khoom Ua Tau Raws Li Txheej Txheem Kev Cai
Cobalt-nickel alloys zoo li AMS 5387 thiab T800 tsis teb rau cov kev coj ua hauv kev tshawb fawb. Lawv lub siab melting point, tsis tshua muaj fluidity, thiab nruj heev kub tearing nyiam xav kom tailored mus kom ze: tighter binder ratios, preheated pwm saum toj no 250 ° C, thiab tswj cov cua txias ntsuas los ntawm embedded thermocouples. Peb tau nchuav ntau tshaj 1,700 kg ntawm T800 nyob rau hauv 18 lub hlis dhau los - thiab txhua batch nqa tag nrho traceability: tshav kub tooj, spectrographic tsom xam, thiab as-cam microstructure duab uas qhia dendrite caj npab nrug nyob rau hauv 25 µm.
Qhov kev qhuab qhia no txuas ntxiv tshaj li kev tuav alloy. Rau hlau castings siv nyob rau hauv engineering tsheb winch center ncej chais, peb xyuas graphite nodule suav (ASTM E2567) thiab ferrite/pearlite piv * ua ntej * machining pib. Vim li cas? Vim tias 5% pearlite ntau dhau ua rau lub sijhawm sib tsoo ntawm 37% thiab txiav cov cuab yeej lub neej hauv ib nrab. Peb ntsuas nws - tsis twv nws.
Qhov "Precision" tiag tiag txhais tau li cas hauv kev xyaum
Precision nyob rau hauv xuab zeb casting tsis yog hais txog caum micron-theem kam rau ua ntawm qhov loj. Nws yog hais txog kev kwv yees. Peb lub peev xwm raug: ± 0.3 hli ntawm cov yam ntxwv txog li 600 hli, ± 0.5 hli ntawm qhov siab tshaj 1,200 hli-nrog CMM-tsim cov ntawv tshaj tawm thawj zaug suav nrog tsis muaj nqi ntxiv. Tab sis qhov tseem ceeb tshaj yog peb lub voj voog tawm tswv yim: yog tias koj daim duab hu rau 12.5 µm Ra tiav ntawm lub tshuab ua haujlwm, peb yuav chij seb lub ntsej muag zoo li cas yuav xav tau 2.1 hli lossis 3.4 hli ntawm cov khoom tshem tawm - thiab yuav ua li cas cuam tshuam rau qhov txo qis thiab nce qhov kev tso kawm.
- Siab li qub: GD & T-raws li lub rooj zaum qhov chaw, txheeb xyuas nrog huab cua gaging thiab xau-kuaj ntawm 1.5 × ua haujlwm siab
- Piston twj tso kua mis lub tog raj kheej vaj tse: Bore concentricity tuav rau 0.025 hli TIR hla 450 hli ntev
- Tsis yog-tus qauv cobalt alloy nozzles: Phab ntsa thickness variation tswj nyob rau hauv ± 0.18 hli ntawm 8 hli yam tsawg kawg nkaus
Peb tsis kho casting thiab machining raws li ib tug cais department. Lawv yog cov theem ua ntu zus ntawm ib tus txheej txheem-yog li tus neeg ua haujlwm CNC tshuaj xyuas cov CT scan ua ntej sau thawj cov cuab yeej. Qhov no yog li cas koj tsis txhob nrhiav pom porosity nyob rau hauv ib qho tseem ceeb foob av tom qab 14 teev ntawm milling.
Xaiv ib tug khub uas muab—tsis yog cog lus xwb
A xuab zeb casting foundry Hoobkas yuav tsum teb peb nqe lus nug ua ntej koj kos npe rau PO: Lawv puas tuaj yeem tuav koj qhov kev zam nruj tshaj plaws ntawm qhov nyuaj tshaj plaws geometry * hauv kev tsim khoom *, tsis yog hauv cov qauv? Puas yog lawv muaj lawv cov ntaub ntawv pov thawj - lossis cia siab rau cov ntaub ntawv xa khoom? Thiab thaum muaj qhov sib txawv ntawm qhov sib txawv, lawv puas qhia cov ntaub ntawv hauv paus (cov xuab zeb permeability cav, yaj tsom xam nkhaus, X-ray ceev maps) los yog tsuas yog muab daim ntawv kho kom raug?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm raws li ISO 9001: 2015 nrog cov ntaub ntawv tshuaj xyuas cov txheej txheem rau txhua qhov ntau ntau. Txhua cov ntaub ntawv raw ntau tau ntawv pov thawj, txhua qhov kev kho cua sov tau nkag mus, txhua yam khoom tiav pom pom hauv qab 10 × magnification. Peb pab cov neeg muas zaub nyob rau hauv North America, Europe, thiab Southeast Asia - tsis yog los ntawm cov brokers, tab sis los ntawm kev sib tham ncaj qha engineering: GD&T txhais, manufacturability tawm tswv yim nyob rau hauv 48 teev, thiab cov khoom tshiab txhua lub limtiam nrog cov ntaub ntawv pov thawj ntawm cov ntsiab lus tseem ceeb.
Lub neej yav tom ntej ntawm precision xuab zeb casting yog nyob rau hauv hybrid workflows - qhov twg casting txhais cov geometry thiab kev ncaj ncees, thiab machining muab cov chaw ua haujlwm thiab nruj haum. Qhov ntawd yuav tsum muaj kev pom kev sib sib zog nqus metallurgical, nruj txheej txheem coupling, thiab xoom kam rau qhov kev xav. Yog tias koj qhov project tom ntej no xav tau qhov ua tau zoo - tsis yog haum - pib nrog cov txheej txheem kom meej, tsis yog nqe nqe lus xwb.
