Thaum engineers qhia a complex hlau casting Hoobkas, lawv tsis thov tsuas yog lwm qhov chaw tsim khoom. Lawv tab tom nrhiav ib tus khub uas nkag siab tias 0.02 hli kam rau ntawm AMS 5387 cobalt alloy twj tso kua mis vaj tsev tsis yog qhov kev thov - nws yog qhov tsis tuaj yeem sib tham rau lub cev muaj sia nyob hauv qab 400 bar hydraulic siab.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau cam khwb cia thiab machined tshaj 12,000 cim geometries rau hydraulic li qub, piston twj tso kua mis lub tog raj kheej vaj tse, thiab winch center ncej rollers-qhov chaw uas microstructural cais los yog residual kev nyuaj siab nyob rau hauv 300 teev ua hauj lwm tsis ua hauj lwm. Peb tau pom cov neeg siv khoom hloov chaw muag khoom tom qab peb qhov sib law liag ua tsis tiav CMM pov thawj ntawm flange interface. Peb kuj tau pom lawv txuas ntxiv kev cog lus los ntawm ob xyoos tom qab lawv thawj T800 cobalt-raws li nozzle dhau 15,000-lub voj voog erosion kuaj yam tsis muaj qhov seem.
Yog vim li cas "Complex" tsis yog hais txog Geometry-Nws yog hais txog Metallurgical Control
Muaj tseeb complexity pib ua ntej lub pwm yog poured. Cov xuab zeb-cam khwb cia hlau twj tso kua mis lub hauv paus yuav zoo li yooj yim - tab sis yog tias nws anchors 2,000 HP offshore roj twj tso kua mis, nws cov graphite nodule suav yuav tsum nyob nruab nrab ntawm 120-160 / mm², nws cov ntsiab lus pearlite ≥92%, thiab nws qhov sib txawv ntawm qhov nyuaj ntawm 1.2 m baseplate tuav rau ± 3 HBW. Qhov theem ntawm qhov sib xws xav tau kev saib xyuas lub sijhawm tiag tiag thaum lub sijhawm ua kom khov - tsis yog kev tshuaj xyuas tom qab ua tiav.
Peb embed thermocouples ncaj qha rau hauv pwm kab noj hniav rau qhov tseem ceeb castings. Peb cov txheej txheem engineers kho qhov kub thiab txias, qhov rooj tsim, thiab qhov cua txias raws li nyob rau hauv thermal profiles - tsis yog cov kab kos zoo li qub. Rau cobalt-nickel alloys zoo li AMS 5387, peb preheat pwm rau 850 ° C thiab tuav lawv rau 90 feeb. Kev hla cov kauj ruam no ua rau micro-porosity ntawm cov ciam teb nplej, uas tom qab ntawd dhau los ua cov ntsiab lus pib tawg nyob rau hauv kev thauj khoom cyclic.
Qhov kev qhuab qhia no piav qhia vim li cas peb cov hlau castings ua tiav repeatability ntawm ± 0.015 hli ntawm qhov tseem ceeb bores- tsis yog qhov tseeb xwb - thiab vim li cas peb cov hlau tsis xeb hlau tuav Ra ≤0.8 µm raws li-cam khwb cia rau ntawm qhov chaw sib khi, tshem tawm cov kev sib tsoo thib ob hauv 68% ntawm kev txiav txim.
Vertical Integration Uas Ua Tau Zoo Tshaj Plaws Dimensional Stability
Ntau lub khw "ib-nres" outsource kev kho cua sov lossis ua tiav. Qhov ntawd tsim cov qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Peb tswj txhua theem-los ntawm cov khoom tau txais raw khoom mus rau qhov kawg kev ua haujlwm xeem-hauv ib lub chaw ISO-certified.
- Casting: Peev casting rau nyias-walled cobalt nozzles; resin-bonded xuab zeb casting rau loj steel twj tso kua mis foundations txog li 1,800 kg
- Tshuab dhos: 5-axis CNC nrog cov txheej txheem kev soj ntsuam rau ntau qhov chaw sib dhos (piv txwv li, sib piv bore axis rau mounting lub ntsej muag nyob rau hauv 0.008 hli tag nrho cov cim nyeem)
- Kev kho cua sov: Nqus annealing rau T800 alloys; tswj-atmosphere hardening rau martensitic stainless castings
- Ua tiavElectropolishing rau corrosion kuj; txhaj tshuaj peening rau qaug zog lub neej extension ntawm winch shafts
Thaum cov neeg siv khoom nyob sab Europe xav tau cov khoom siv tsis yog tus qauv piston twj tso kua mis lub tog raj kheej nrog cov cua txias sab hauv thiab cov iav sab nraud, peb tau khiav kev simulation ua ntej, tom qab ntawd txheeb xyuas cov phab ntsa tuab ntawm CT scanning - tsis yog kuaj ultrasonic xwb. Tsuas yog tom qab ntawd peb tau clamp qhov chaw rau machining. Qhov tshwm sim? Thawj tsab ntawv lees txais ntawm Tier-1 OEM audit. Tsis muaj rework. Tsis muaj kev ncua.
Kev Ua Tau Zoo Ua Hauv - Tsis Tshuaj Xyuas Hauv
Peb tsis tos qhov kev tshuaj ntsuam zaum kawg kom ntes tau cov teeb meem. Txhua batch nqa tag nrho traceability: cua sov tooj, yaj tsom xam daim ntawv qhia, casting ntau ID, CNC program version, tus neeg teb xov tooj ID, thiab CMM soj ntsuam cav - tag nrho cov txuas digitally. Yog tias lub siab valve ua tsis tau qhov ntsuas hydrostatic, peb rub tib lub sijhawm kub ntawm cov khoom siv hauv casting, rov ua dua tensile tests, thiab sib piv cov duab microstructure ib sab nrog ntau ntau tau txais ua ntej.
Peb qhov kev tshuaj xyuas tuaj tsis yog lub thawv-check. Rau cobalt alloys, peb txheeb xyuas AMS 5387 ua raws li siv OES spectroscopy - tsis yog tsuas yog daim ntawv pov thawj zeb. Peb xyuas cov nplej loj ib ASTM E112 ntawm txhua qhov thib peb casting. Peb ua dye penetrant testing ntawm tag nrho cov machined sealing nto-txawm thaum tsis tau teev-vim kev paub qhia tau hais tias 22% ntawm nto-breaking flaws tshwm tsuas yog tom qab kawg machining kev nyuaj siab nyem.
Qhov kev nruj no muab cov txiaj ntsig ntsuas tau: 99.4% first-pass yield ntawm cobalt alloy Cheebtsam; xoom teb rov qab rau qhov tsis sib haum xeeb hauv 2023; thiab lub sij hawm nruab nrab ntawm 18 hnub rau cov qauv castings - nqis los ntawm 32 hnub kev lag luam thoob plaws.
Kev sib koom tes tiag tiag pib ua ntej kos duab tiav
"Koj puas tuaj yeem ua qhov no?" yog thawj lo lus nug tsis raug. Txoj cai yog: "Yuav ua li cas yog tias peb txo cov tav tuab ntawm 1.2 hli?" Peb khiav kev tshuaj xyuas kev tsim khoom-tsis yog tus neeg saib xyuas, tab sis yog cov neeg koom tes. Peb chij GD&T tsis sib haum thaum ntxov: txoj hauj lwm kam rau hu rau ± 0.01 hli ntawm 200 hli txoj kab uas hla nto, thaum lub hauv paus casting kam rau ua yog ± 0.3 hli. Peb xav kom lwm cov datuming lossis hloov kho cov duab kos uas khaws cia ua haujlwm tab sis txiav tus nqi los ntawm 27%.
Peb txhawb North American, European, thiab Southeast Asian cov neeg siv khoom los ntawm kev sib tham ncaj qha engineering - tsis yog los ntawm cov txheej txheem txhais lus. Thaum lub tuam txhab German twj tso kua mis rov tsim kho lawv lub cev lub cev kom txo qhov hnyav, peb tau thov hloov los ntawm 316 stainless hlau casting rau duplex 2205 - tib qhov kev ntsuam xyuas corrosion, 22% siab dua yield zog, thiab tsis xav tau kev kho cua sov tom qab vuam. Lawv tau txais nws. Lawv qhov kev txiav txim tom ntej ob npaug.
Yog tias koj daim ntawv thov xav tau complex hlau casting Hoobkas muaj peev xwm - tsis yog lub peev xwm xwb - koj xav tau kev qhuab qhia metallurgical, kev tswj cov txheej txheem, thiab xoom kam rau qhov kev xav. Koj xav tau cov neeg koom tes uas kho txhua qhov casting zoo li nws tuav rov qab 400 bar ntawm hydraulic zog-los yog khaws cov dej hauv ntug dej hiav txwv uas muaj nyob ntawm 3,000 meters qhov tob. Nov yog tus qauv peb tsim los. Txhua hnub.
