Thaum engineers qhia a casting Hoobkas rau precision hlau qhov chaw, lawv tsis yog tsuas yog xaj hlau-lawv tab tom twv ntawm qhov ruaj khov nyob rau hauv 300-bar hydraulic loads, microstructure kev ncaj ncees tom qab kev kho cua sov, thiab xoom kam rau porosity hauv cobalt alloy nozzles. Peb tau pom ntau txoj haujlwm qeeb - tsis yog los ntawm kev tsim teeb meem, tab sis los ntawm qhov tsis sib xws ntawm cov peev txheej hauv kev tsim: xuab zeb castings xa mus rau cov khw yam tsis muaj ISO 9001-tso ntawv pov thawj yaj tswj, lossis peev cam khwb cia vaj tsev machined ntawm 3-axis mills uas tsis tuaj yeem tuav ± 0.015 hli ntawm qhov chaw nres nkoj sab hauv.
Vim li cas "Precision Casting" tsis yog ib lo lus lag luam xwb
Muaj tseeb precision casting pib ua ntej thawj ncuav. Nws txhais tau tias xaiv cov khoom siv raw nrog cov ntawv pov thawj zeb xeem ntawv - tsis yog cov npe qib - thiab txheeb xyuas cov tshuaj lom neeg hlau * ua ntej * melting. Ntawm peb qhov chaw nyob hauv Qingdao, txhua qhov AMS 5387 cobalt alloy batch undergoes spectrometric tsom xam thaum tuaj txog. Peb tsis lees txais cov khoom yog tias chromium deviates ntau dua 0.2% los ntawm spec - txawm tias tus neeg muag khoom daim ntawv pov thawj hais tias "ua raws." Vim li cas? Vim tias peb tau ntsuas li cas 0.2% hloov pauv hloov pauv carbide faib hauv piston twj tso kua mis lub tog raj kheej, cuam tshuam ncaj qha rau hnav lub neej hauv kev siv roj siab & roj.
Qhov kev qhuab qhia no txuas ntxiv los ntawm kev tswj cov txheej txheem: tswj cov cua txias hauv cov xuab zeb pwm kom tsis txhob muaj kev ntxhov siab nyob hauv 400-mm-tuab twj tso kua mis; Nqus-pab peev plhaub tsev rau T800 alloy nozzles kom tshem tawm oxide inclusions; CNC machining tam sim ntawd tom qab kev ntxhov siab-relief annealing-tsis tau tom qab cua-txias-kom khaws cia qhov ntev ntawm qhov rov ua dua hla 500-ib feem khiav.
Plaub Lub Taub Hau Uas Tiag Tiag
Cov neeg muag khoom feem ntau sau "CNC + casting" ua cov kev pabcuam cais. Ob peb sib xyaw ua ke kom nruj txaus los lav kev ua haujlwm zoo. Nov yog qhov ua haujlwm hauv kev xyaum:
- Kev paub txog cobalt-nickel superalloy: Tsis yog machining AMS 5387 - tab sis kwv yees nws tus cwj pwm nthuav dav thermal thaum lub sijhawm ua haujlwm ntau. Peb tshuab cobalt alloy plugs nrog cuam tshuam haum yuav tsum tau 0.008 hli xovxwm-haum clearance, ces validate haum-tom qab-kub-kho siv real-time thermal simulation ntawm tag nrho cov txheej txheem saw.
- Vertical kev koom ua ke nrog lub hom phiaj: Peb cov xuab zeb casting kab pub ncaj qha rau hauv CNC cell. Tsis muaj inter-facility logistics. Tsis muaj re-fixturing. Lub 120-kg engineering tsheb winch center ncej cov menyuam mus los ntawm ntsuab xuab zeb pwm mus rau qhov kawg hauv av nyob rau hauv 72 teev - nrog CMM pov thawj ntawm peb theem tseem ceeb: as-casting, tom qab roughing, thiab tom qab tiav.
- GD & T-tsav kev tsim khoom: Peb tsis yog nyeem cov duab kos xwb-peb nug lawv. Thaum tus neeg siv khoom qhia txog txoj haujlwm kam rau ua ntawm Ø0.05 hli ntawm plaub qhov chaw nres nkoj valve bores, peb simulate datum hloov hla casting shrinkage thiab machining deflection. Yog tias muaj kev pheej hmoo siab tshaj 15%, peb chij nws * ua ntej * cov cuab yeej - txuag lub lis piam thiab tus qauv qauv.
- Traceability uas xa cov ntaub ntawv pov thawj, tsis yog ntaub ntawv: Txhua lub siab valve nqa QR code txuas mus rau nws cov keeb kwm tag nrho: yaj ID, casting ntau, kho cua sov lub voj voog cav, CMM daim ntawv teev sijhawm, thiab txawm tias tus neeg teb xov tooj kos npe tawm ntawm kev tshuaj xyuas zaum kawg. Tsis yog "ua raws" - pov thawj.
Tus nqi zais ntawm "Zoo txaus" Foundry Partners
Qee tus neeg yuav khoom tseem ceeb tshaj tus nqi qis dua ntawm cov txheej txheem nruj. Peb nkag siab tias yog vim li cas—txog thaum lawv ntsib kev ua tsis tiav. Ib qho North American hydraulic OEM tau txais 12% qis dua los ntawm lwm tus casting Hoobkas. Qhov tshwm sim? 23% ntau dua qhov seem ntawm lub tog raj kheej vaj tse vim qhov tsis pom qhov subsurface shrinkage. Re-machining ua tsis tau tejyam los kho phab ntsa thickness uniformity. Lub sijhawm ua haujlwm tau ncav cuag 11 lub lis piam. Tag nrho cov nqi tsaws tau nce 37%.
Hloov pauv, cov neeg siv khoom uas koom nrog peb thaum ntxov - thaum kos duab tshuaj xyuas - pom cov txiaj ntsig sib txawv. Rau cov chaw tsim khoom European twj tso kua mis, peb tau txheeb xyuas tias qhov tsis yog tus qauv taper ntawm AMS 5387 twj tso kua mis tuaj yeem ua tiav los ntawm qhov ze-net-shaped peev casting es tsis txhob tag nrho CNC cov khoom tshem tawm. Cov khoom txuag: 64%. Machining lub sij hawm txo los ntawm 18.2 mus rau 4.7 teev ib feem. Thawj tsab ntawv pom zoo dhau hnub 1.
Dab tsi Precision Demans Hnub no—thiab tag kis
Precision tsis zoo li qub. Raws li cov neeg ua haujlwm roj & roj thawb cov twj tso kua mis mus rau 10,000 psi thiab offshore winches ua haujlwm ntawm -40 ° C, cov khoom siv hloov pauv. Peb lub hom phiaj R & D tsis yog ntawm cov tshuab loj dua - nws yog nyob rau ntawm kev sib txuas nruj dua ntawm kev sib tsoo metallurgy thiab tom qab txheej txheem geometry. Tam sim no, peb tau lees paub cov txheej txheem hybrid: peev casting ua raws li laser-pab hauv cheeb tsam hardening ntawm lub rooj zaum ntawm lub rooj zaum, tom qab ntawd ua tiav kev sib tsoo nrog cov txheej txheem kev tswj xyuas kom pom micro-chatter ua ntej nto roughness tshaj Ra 0.4 µm.
Yog tias koj qhov phiaj xwm tom ntej yuav tsum muaj qhov tsis ua haujlwm txhais tau tias tsis muaj sijhawm poob, kev pheej hmoo kev nyab xeeb, lossis kev tswj hwm tsis ua raws cai - xaiv tus khub uas nws txhais tau tias "qhov tseeb" nyob hauv cov ntaub ntawv, tsis yog daim ntawv qhia. Xaiv ib casting Hoobkas uas kho txhua qhov casting zoo li lub luag haujlwm tseem ceeb ntawm lub luag haujlwm-vim hauv hydraulic systems, engineering tsheb, thiab cov twj tshwj xeeb, nws yog.
