Thaum lub tshuab hydraulic ua tsis tau raws li 350-bar siab, thaum lub twj tso kua mis lub tsev tawg tom qab 12,000 teev ua haujlwm, lossis thaum cobalt-nickel nozzles eroded sai dua li qhov xav tau - engineers tsis thuam tus tsim. Lawv taug qab nws rov qab mus rau ib qho kev txiav txim siab: cov khoom siv ncaj ncees ua ke nrog qhov kev ncaj ncees ntawm qhov nickel-based alloy mechanical qhov chaw Hoobkas.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tau siv ntau tshaj kaum xyoo los daws qhov teeb meem tiag tiag - tsis yog nyob rau hauv txoj kev xav, tab sis nyob rau hauv pem teb khw. Peb tau pom AMS 5387 castings warp thaum kho cua sov vim tias cov qauv tsis sib xws. Peb tau rov ua dua T800 alloy nruab nrab ncej chais peb zaug vim micro-cracks zais hauv qab qhov kawg. Cov no tsis yog hypotheticals. Lawv yog cov tshooj lus qhia uas zoo li peb tshuab, nrum, thiab siv tau txhua qhov.
Vim li cas nickel-raws li alloys xav tau ntau dua li CNC muaj peev xwm
Nickel-raws li alloys xws li Inconel 718, Hastelloy C-276, thiab AMS 5387 tiv thaiv corrosion thiab tuav lub zog siab tshaj 650 ° C - tab sis lawv kuj ua hauj lwm-harden sai, ua cua sov tsis zoo, thiab hnav tej cuab yeej aggressively. Lub khw CNC txheem tsis tuaj yeem tuav ± 0.01 hli kam rau ntawm 420-mm-inch piston twj tso kua mis lub tog raj kheej lub tsev nyob ua los ntawm T800 alloy yam tsis muaj kev siv cuab yeej cuab tam, thermal stabilization cycles, thiab in-process metrology.
Tias yog vim li cas kev sib koom ua ke ntsug tseem ceeb. Ntawm peb lub chaw Qingdao, casting tsis yog outsourced. Xuab zeb casting thiab peev casting tshwm sim nyob rau hauv ib lub ru tsev - ib sab ntawm ntau lub tshuab machining chaw calibrated txhua hnub. Peb tswj pwm preheat kub, solidification npaum li cas, thiab post-cast stress nyem nyem ua ntej thawj txiav. Tsis muaj handoffs. Tsis muaj batch-rau-batch variation nyob rau hauv dendritic spacing. Tsuas yog rov ua tau microstructure - thiab qhov ntawd yog qhov chaw ruaj khov pib.
Peb sim no txhua hnub: ib tug neeg thov 18 zoo tib yam cobalt alloy plugs rau high-pressure roj manifolds. Batch 1 dhau CMM tshuaj xyuas tab sis ua tsis tiav kev sim tawg ntawm 412 bar. Micro-CT qhia pom qhov porosity maj mam nyob ze ntawm lub xub pwg sealing - tsis tuaj yeem kuaj pom los ntawm qhov chaw gaging. Peb kho qhov rooj tsim, txo qis qhov kub ntawm 23 ° C, thiab ntxiv ultrasonic kev co thaum lub sij hawm solidification. Batch 2 tuav 487 bar. Cov theem ntawm kev tswj tsuas yog muaj thaum casting thiab machining engineers zaum ua ke thaum DFMA tshuaj xyuas.
Qhov "precision" tiag tiag txhais tau li cas rau lub hom phiaj tseem ceeb
Precision tsis yog nruj kam rau ua. Nws yog kev sib raug zoo ntawm geometry, metallurgy, thiab kev pabcuam ib puag ncig. Lub siab valve lub cev yuav tsum kaw-tab sis nws yuav tsum muaj sia nyob thermal cycling yam tsis muaj kev tawg ntawm qhov sib txuas. Lub winch nruab nrab ncej cov menyuam yuav tsum tig mus zoo-tab sis nws cov tawv tawv yuav tsum siab tshaj HRC 52 * thiab * tswj cov av tawv tawv kom tiv thaiv kev sib kis.
Yog vim li cas peb cov txheej txheem zoo embeds pov thawj ntawm plaub lub ntsiab lus tsis sib tham:
- Raw khoom validation: Txhua lub kauj lossis ingot nqa tag nrho MTRs, suav nrog kev tshuaj xyuas spectrographic thiab cov ntawv qhia loj - tsis yog ntawv pov thawj qib
- Kev kuaj CMM hauv-tus txheej txheem: Tom qab roughing, semi-finishing, thiab xov-ntawm tib lub tshuab calibrated, siv tib lub tswv yim datum
- Kev kuaj ua haujlwm: Siab li qub kuaj ntawm 1.5 × rated siab; twj tso kua mis vaj tse spin-balanced thiab xau-kuaj nrog helium huab hwm coj spectrometry
- Tag nrho traceability: Txhua qhov txuas mus rau nws tus lej xov tooj cua sov, machining program version, tus neeg teb xov tooj ID, thiab lub sijhawm tshuaj xyuas
Qhov no tsis yog over-engineering. Nws tau zam tus nqi $ 280,000 downtime thaum ib lub tog raj kheej tawg ntho lub qhov dej tawm ntug dej hiav txwv cov av nkos rau 72 teev.
Qhov twg customization tsis txaus ntshai - thiab pib xa ROI
Qee tus neeg muag khoom kho qhov tsis yog tus qauv raws li kev zam. Peb kho lawv raws li lub sijhawm los tshem tawm cov kev ua tsis tiav. Xyoo tas los, European OEM coj peb kos duab rau kev cai AMS 5387 nozzle nrog asymmetric txias raws. Lawv tus neeg muag khoom ua ntej tau hais tawm 14 lub lis piam thiab tsis lees txais kev lav phib xaub rau kev sib txawv ntawm ± 8%. Peb tau khiav thermal simulation, rov tsim kho sab hauv baffles txhawm rau txhim kho kev sib tw nrawm, thiab xa hauv 9 lub lis piam - nrog kev sib txawv ntawm qhov ntsuas ntawm ± 2.3% ntawm tag nrho 12 units.
Yuav ua li cas? Los ntawm kev kho GD&T tsis yog cov ntaub ntawv, tab sis ua lus ua haujlwm. Thaum daim duab qhia txog txoj hauj lwm kam rau ua ntawm Ø0.05 hli txheeb ze rau lub datum axis, peb xyuas cov axis * ua ntej * machining - tsis yog tom qab. Thaum nto tiav hu rau Ra 0.4 µm ntawm lub ntsej muag sealing, peb siv pob zeb diamond tig-tsis sib tsoo-vim kev sib tsoo ua rau muaj kev puas tsuaj subsurface uas pib ua rau qaug zog tawg hauv kev thauj khoom.
Qhov kev qhuab qhia ntawd ntsuas. Txawm hais tias koj xav tau tsib lub qauv siab li qub lossis 300 lub hauv paus twj tso kua mis hauv ib lub hlis twg, peb cov kev ua haujlwm lean locks nyob rau hauv lub sij hawm voj voog, cov khoom yield, thiab thawj-pass yield-tsis muaj kev cuam tshuam metallurgical tswj.
Xaiv ib tus khub - tsis yog tus neeg xa khoom nkaus xwb - rau cov khoom siv hlau nplaum nickel
Txoj cai nickel-based alloy mechanical qhov chaw Hoobkas tsis tsuas yog ua tau raws li specs. Nws cia siab tias qhov twg specs poob luv. Nws paub tias AMS 5387 lub zog tensile poob 12% yog tias cov tshuaj annealing tshaj 1180 ° C - txawm tias MTR hais tias "nyob rau hauv ntau yam." Nws nkag siab tias xuab zeb-cam khwb cia T800 yuav tsum muaj qhov sib txawv ntawm kev txhaj tshuaj-peening tsis ntau dua li cov peev txheej-cam khwb cia-vim qhov seem seem kev ntxhov siab sib txawv.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm ntawm qhov kev sib tshuam ntawm cov ntaub ntawv science thiab precision manufacturing. Peb tsis khaws cov khoom siv dav dav. Peb engineers txheej txheem ua ntu zus nyob ib ncig ntawm koj cov khoom ua haujlwm-tsis yog peb lub tshuab muaj peev xwm. Peb lub chaw ISO-raws li nyob rau hauv Qingdao muab ntawv pov thawj cobalt-nickel Cheebtsam rau North America, Europe, thiab Southeast Asia - tsis raws li cov khoom catalog, tab sis raws li validated kev daws teeb meem.
Yog tias koj qhov project tom ntej no suav nrog kev kub siab, kub siab, lossis qhov chaw hnav siab-thiab koj xav tau qhov chaw uas ua raws li tsim, ua haujlwm tom qab ua haujlwm, xyoo tom qab xyoo-pib nrog cov khoom siv traceability, dimensional rigor, thiab real-world validation. Tsis yog daim ntawv qhia. Tsis cog lus. Kev ua pov thawj.
