Thaum lub twj tso kua mis hydraulic lub tsev tawg nyob rau hauv 350-bar siab-los yog cobalt alloy nozzle ua tsis tiav tom qab 420 teev ntawm qaub-gas kev pab cuam - qhov teeb meem tsis yog ib feem tsis ua hauj lwm. Nws yog ib qho kev sib tawg ntawm cov saw hlau ntawm kev xav tsim thiab metallurgical kev muaj tiag. Qhov kev sib txawv ntawd yog qhov twg precision hlau casting khwv tau nws qhov hnyav - tsis yog raws li cov txheej txheem khoom, tab sis raws li kev tswj hwm, kev tshawb fawb-coj kev txuas ntxiv ntawm kev txiav txim siab engineering.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom qhov kev ua si no thoob plaws 178 txoj haujlwm rau North American oilfield OEMs, German hydraulic system integrators, thiab cov neeg ua haujlwm South Asian marine twj tso kua mis. Ib tus neeg siv khoom xa tuaj rau peb GD&T-hnyav kos duab rau AMS 5387 piston twj tso kua mis lub tog raj kheej vaj tse-tightest kam rau ua: ± 0.015 hli ntawm tus ID bore, nto tiav Ra ≤ 0.8 µm, xoom sab hauv porosity ntawm qhov chaw muaj kev ntxhov siab. Lawv cov neeg xa khoom ua ntej xa 12 qhov chaw. Tsuas yog 3 dhau kev kuaj ultrasonic. Peb khiav tag nrho cov txheej txheem simulation ua ntej: solidification modeling, thermal gradient mapping, gating optimization. Tom qab ntawd cam khwb cia, tshav kub-kho, CNC-tiav, thiab CMM-tuaj xyuas txhua chav. Tag nrho 24 tau dhau los. Qhov txawv tsis yog hmoov zoo. Nws yog casting kev qhuab qhia fused nrog machining tswj.
Muaj tseeb precision hauv hlau casting pib ua ntej pwm kov cov xuab zeb lossis ceramic. Nws pib nrog kev lav ris khoom siv. Peb qhov chaw cobalt-nickel alloys tsuas yog los ntawm cov mills muab tag nrho cov ntaub ntawv pov thawj thaum tshav kub kub-AMS 5387, UNS R30006, T800-qib-tam sim no rau yaj tooj, tshuaj reanalysis, thiab grain loj pov thawj. Tsis muaj "batch averages." Tsis muaj daim ntawv pov thawj xa khoom xa tuaj yam tsis muaj kev kuaj xyuas thib peb. Thaum lub tuam txhab European valve xav tau 19mm-inch cobalt alloy plugs rau H₂S cov kev pabcuam, lawv tau xa peb lawv cov ASTM A995 Level II spec - thiab peb tau sib npaug rau 0.03% carbon sib txawv. Qhov kev ntseeg siab ntawd tsis tshwm sim hauv cov khw muag khoom uas kho cov kev xaiv alloy raws li lub checkbox.
Vertical kev koom ua ke tsis yog kev lag luam jargon ntawm no - nws yog qhov kev ruaj ntseg zoo li cas tau xauv rau hauv. Xuab zeb casting ib leeg tsis tuaj yeem tuav ± 0.02 hli ntawm 320-mm-ntev twj tso kua mis. Tsis tuaj yeem CNC machining ib leeg raug rau micro-shrinkage hauv high-alloy steel castings. Tab sis thaum casting, kev kho cua sov, thiab 5-axis milling tshwm sim nyob rau hauv ib lub ru tsev - nrog rau kev sib koom metrology, synchronized txheej txheem qhov rais, thiab kev sib koom GD&T tshuaj xyuas - lub stack-up yuam kev vau. Peb niaj hnub tuav 0.008 hli flatness ntawm stainless hlau castings ntsuas 420 × 280 × 95 mm-tom qab kev ntxhov siab-relieving, roughing, semi-tiav, thiab zaum kawg nyuaj-tig. Qhov ntawd yuav tsum tau them nyiaj thermal ntawm lub sijhawm ntawm CNC, tsis yog kev kho tom qab kev kho.
- Tsis muaj "black box" casting: Txhua hlau los yog steel casting khiav los ntawm solidification simulation; Txhua qhov cobalt alloy tau txais pre-cast microstructure validation ntawm optical emission spectroscopy + SEM chaw kuaj xyuas
- Tsis siv neeg dig muag machining: CMM cov ntaub ntawv los ntawm cam khwb cia blanks pub ncaj qha rau hauv CNC toolpath optimization-txo cov khoom tshem tawm txog li 37% ntawm cov vaj tsev nyuaj
- Tsis muaj ntawv nkaus xwb QA: Traceability tsis yog kev nkag mus rau hauv database. Nws yog lub cev tag laser-engraved ntawm txhua ntu, txuas rau cov ntaub ntawv pov thawj raw khoom, NDT cov ntaub ntawv, cov ntaub ntawv kho cua sov, thiab cov duab soj ntsuam zaum kawg
Ib txhia xav tias peev casting cia li sib npaug siab dua precision dua xuab zeb casting. Tsis muaj tseeb. Ib tug tsis zoo gated peev plhaub distorts thaum lub sij hawm dewaxing. Cov xuab zeb rushed pwm txias tsis sib npaug, tsim kom muaj kev ntxhov siab nyob rau hauv uas warps thaum machining. Dab tsi tseem ceeb yog cov txheej txheem kev txawj ntse - tsis yog hom pwm. Peb siv cov xuab zeb casting rau qhov loj, cov khoom ntim qis xws li engineering tsheb winch center ncej chais (txog 1,200 kg), vim tias tswj cov cua txias thiab cov tub ntxhais cov ntawv luam tawm zoo dua macro-hardness uniformity tshaj peev rau cov ntu tuab. Rau me me, nyias-walled cobalt nozzles? Kev nqis peev yeej-tab sis tsuas yog nrog lub tshuab nqus-pas dej thiab kev tswj xyuas kev ruaj ntseg. Precision tsis ci rau hauv txoj kev. Nws yog engineered rau hauv txhua qhov kev txiav txim.
Saib ua ntej: Cov pem hauv ntej tom ntej tsis yog qhov cub loj dua lossis nrawm dua CNC spindles. Nws yog hybrid txheej txheem tswj-qhov twg casting simulation outputs pub nyob thermal qauv nyob rau hauv machining chaw, qhov twg in-situ strain sensors kho toolpaths nruab nrab-txiav, qhov twg cov ntxaib digital validate qaug zog lub neej ua ntej thawj ncuav. QINGDAO QIANGSENYUAN TECHNOLOGY tab tom tsim lub peev xwm tam sim no - tsis yog kev sim ua haujlwm, tab sis raws li kev tsim khoom tsim khoom. Peb tau lees paub rau AS9100 rau aerospace-tseem ceeb twj tso kua mis. Peb tsim nyog HIP (kub isostatic nias) rau ze-net cobalt castings. Thiab peb yog cov kws tshaj lij kev cob qhia tsis yog los nyeem cov phiaj xwm-tab sis txhawm rau twv seb cov hlau molten yuav coj li cas hauv cov duab kos duab tshwj xeeb, nyob rau hauv cov xwm txheej txias txias, nrog rau kev txheeb xyuas cov tshuaj lom neeg.
Foundry hlau casting tsis yog hais txog nchuav hlau rau hauv cov duab. Nws yog hais txog kev txhais cov kev xav tau-siab ncaj ncees, hnav tsis kam, thermal stability-rau metallurgical tseeb. Qhov ntawd xav tau ntau tshaj li cov khoom siv. Nws xav tau kev paub nrog AMS 5387 cracking hom. Nws xav tau kev txawj ntse hauv GD & T-tsav casting nyiaj pub dawb. Nws xav tau kev ntseeg siab ua ntau dua 217 qhov kev tsim khoom siv tau siv tau-tsis tau cog lus. Yog hais tias koj tom ntej no lub siab-siab valve vaj tse, piston twj tso kua mis, los yog tshwj xeeb alloy qhov chaw yuav tsum tau ua - tsis yog tsuas yog ciaj sia - ces precision pib ntev ua ntej thawj spark hits lub workpiece.
