Thaum cov engineers qhia ib feem uas yuav tsum tuav ± 0.02 hli kam rau ua nyob rau hauv 350-bar hydraulic siab - thiab muaj sia nyob 10,000+ cycles nyob rau hauv abrasive slurry - tsis muaj chaw rau casting kwv yees. Qhov ntawd yog qhov twg peev casting kev pab cuam Hoobkas nrog pov thawj metallurgical kev qhuab qhia, tsis yog tsuas yog pwm-ua muaj peev xwm, ua tsis yog-negotiable. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau xa ntau tshaj 17,000 precision castings txij li xyoo 2018 rau cov twj tso kua mis, cobalt alloy nozzles, thiab winch center ncej chais-txhua qhov chaw traceable rau cua sov tooj, tshuaj xyuas nrog Zeiss CMMs, thiab 5 AST38 validated ua ntej AMS 9.
Vim li cas Kev nqis peev Casting tsis yog "lwm txheej txheem" rau qhov ua tau zoo
Ntau tus neeg muag khoom kho cov peev txheej casting raws li cov khoom lag luam: ncuav wax, dip slurry, hlawv tawm, ncuav hlau, tiav. Tab sis hom kev ua tsis tiav tiag tiag hauv ntiaj teb qhia ib zaj dab neeg sib txawv. Peb tau pom piston twj tso kua mis lub tog raj kheej lub tsev nyob tawg ntawm lub flange interface - tsis yog los ntawm kev tsim yuam kev, tab sis vim hais tias cov foundry siv cov khoom siv cobalt-nickel uas tsis muaj kev pov thawj spectral. Peb tau pom lub siab li qub tom qab 200 teev vim tias kev sib cais ntawm cov ciam teb tsis tau tswj xyuas thaum lub sij hawm khov. Cov no tsis yog qhov kev pheej hmoo theoretical. Lawv yog qhov ua tsis tiav uas peb kuaj tau txhua hnub hauv peb qhov chaw ISO 9001-certified hauv Qingdao.
Muaj tseeb precision pib ua ntej thawj wax qauv. Peb cov engineers tshuaj xyuas GD&T callouts * nrog * koj daim duab - tsis yog tom qab quoting. Yog tias koj lub cev lub cev qhia txog Rz 0.8 µm nto tiav ntawm cov dej ntws sab hauv, peb paub meej tias qhov ntawd puas tuaj yeem ua tiav tom qab-casting lossis yuav tsum tau ua tiav CNC tiav. Yog tias koj lub AMS 5387 plug xav tau xoom porosity nyob rau hauv qhov tseem ceeb 3-mm phab ntsa ntu, peb kho lub plhaub thickness, preheat kub, thiab ncuav tshaj tawm - tsis yog tsuas yog khiav cov qauv tsis. Qhov no tsis yog kev saib xyuas. Nws yog kev ua tswv cuab.
Plaub Muaj Peev Xwm Uas cais Precision Los ntawm Kev cog lus
Peb tsis outsource cov kauj ruam tseem ceeb. Txhua yam khoom siv high-alloy txav mus los ntawm plaub ntu sib txuas ua ke - tsis muaj kev sib tw, tsis muaj kev ncua sij hawm:
- Kev tswj cov khoom siv: Txhua T800 cobalt-raws li thiab AMS 5387 alloys yog los ntawm cov ntawv pov thawj mills nrog tag nrho cov ntawv soj ntsuam zeb; Peb rov kuaj txhua qhov ntau rau carbon, chromium, thiab tungsten cov ntsiab lus siv OES spectroscopy
- Casting fidelity: Kev nqis peev casting rau txoj kev geometries (xws li ntau qhov chaw nres nkoj twj tso kua mis), xuab zeb casting rau cov txheej txheem loj dua (piv txwv li, engineering tsheb winch bases) - ob qho tib si ua hauv tsev nrog kev saib xyuas thermal ntawm lub sijhawm.
- Machining kev sib xyaw: 5-axis CNC machining ntawm castings tam sim ntawd tom qab kev ntxhov siab nyem-tsis muaj rov kho, tsis muaj qhov yuam kev ntawm cov ntaub ntawv-tseem ceeb rau coaxiality ntawm bore thiab mounting lub ntsej muag
- Traceability los ntawm kev tsim: Txhua feem yog laser-etched ID txuas nrog nws cov ntaub ntawv pov thawj raw khoom, kev kho cua sov cav, CMM tshuaj xyuas daim ntawv qhia, thiab daim ntawv ntsuam xyuas zaum kawg
Qhov kev sib xyaw ntsug no tshem tawm qhov dav dav dav dav thaum casting thiab machining tshwm sim ntawm cov neeg muag khoom sib cais. Piv txwv li, peb cov cobalt alloy nozzles ua tiav 0.015 mm roundness kam rau ua hla 120 mm ntev - ib yam dab tsi peb tau txheeb xyuas ntau zaus ntawm cov neeg siv khoom 'kev tswj xyuas cov tshuab thaum sib koom ua ke.
Dab tsi cov neeg siv khoom nug tiag tiag—Thiab peb xa dab tsi
"Koj puas tuaj yeem nrum T800 hauv 4.5 kg net hnyav nrog 0.3 hli phab ntsa tuab?" Yog lawm - peb tau tsim 42 units rau subsea tshuaj txhaj twj tso kua mis nrog xoom tsis lees paub.
"Koj puas ua cov kev kho cua sov uas tsis yog tus qauv ntawm AMS 2750?" Yog lawm-peb khiav lub tshuab nqus tsev annealing thiab daws kev laus hauv tsev nrog pyrometer-calibrated rauv, nkag rau hauv AMS 2750E cov cai.
"Koj puas tuaj yeem xa 500 stainless hlau valve lub cev hauv 6 lub lis piam?" Yog lawm - rau qhov kev txiav txim nruab nrab-ntev, peb cov kev ua haujlwm lean xa cov sij hawm ua haujlwm ruaj khov yam tsis tau them nqi kho mob sai.
Peb tsis hais "yog" rau txhua yam. Yog tias koj daim duab qhia pom cov kaum sab xis hauv qab 0.5 ° rau 120-mm-siab aluminium peev casting, peb yuav chij nws - tsis yog vim peb tsis tuaj yeem sim, tab sis vim tias lub plhaub yuav tawg thaum dewaxing. Qhov ntawd tsis yog tsis kam. Nws yog engineering ncaj ncees.
Qhov twg Precision ntsib Partnership
Ib peev casting kev pab cuam Hoobkas khwv tau kev ntseeg tsis yog nyob rau hauv qhov kev tsocai, tab sis nyob rau hauv thawj cov khoom khiav - thiab lub thib kaum. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY, uas txhais tau hais tias siv tau koj qhov kev txhais lus GD&T ua ntej lub cuab yeej pib, sib koom cov ntawv pov thawj raw khoom ua ntej pib casting, thiab xa cov ntaub ntawv soj ntsuam nrog txhua lub thawv. Peb cov neeg siv khoom hauv North America, Lub teb chaws Yelemees, thiab Singapore vam khom qhov sib xws - tsis yog vim peb cog lus tias yuav ua kom tiav, tab sis vim peb tshem tawm qhov hloov pauv tsis tau.
Cov tiam tom ntej ntawm high-alloy Cheebtsam yuav tsis ua tiav ntawm nruj tolerances ib leeg. Lawv yuav thov kom muaj kev sib koom ua ke ntawm kev tsim microstructure thiab machined nto kev ncaj ncees. Tias yog vim li cas peb thiaj li nthuav dav R & D mus rau hauv hybrid casting-machining workflows-qhov ze-net-shaped peev castings yog tiav-machined nyob rau hauv ib qho kev teeb tsa, khaws cia qhov seem tshuav nyiaj li cas. Precision tsis zoo li qub. Tsis yog peb.
