Thaum cov kws tshaj lij qhia cov khoom siv nickel raws li cov khoom siv hlau, lawv tsis yog xaiv cov khoom siv xwb - lawv tau cog lus rau kev ua haujlwm nyob rau hauv siab, kub, thiab corrosion. Ib qho tsis zoo nyob rau hauv qhov chaw ruaj khov lossis microstructure tuaj yeem cuam tshuam rau hauv lub twj tso kua mis tsis ua haujlwm, valve leakage, lossis lub sijhawm tsis tau npaj tseg hauv cov tshuab hydraulic lossis cov khoom siv roj av. Tias yog vim li cas kev tsim khoom los ntawm a nickel raws alloy qhov chaw Hoobkas tsis yog hais txog tus nqi ib leeg-nws yog hais txog kev lav phib xaub ntawm metallurgical, txheej txheem kev qhuab qhia, thiab cov lus teb ua pov thawj rau lub ntiaj teb kev ntxhov siab tiag tiag.
Vim li cas AMS 5387 thiab T800 Xav Tau Ntau Tshaj Li Txheej Txheem Machining
Peb tau pom ntau qhov haujlwm nyob rau ntawm qhov qauv qauv - tsis yog vim kev tsim qauv tsis zoo, tab sis vim tias tus neeg muag khoom tsis muaj kev paub nrog cobalt-nickel superalloys. AMS 5387 cobalt alloy 6 thiab T800-raws li cov ntaub ntawv tsis coj zoo li 316 stainless. Lawv ua hauj lwm hnyav aggressively. Lawv thermal conductivity yog tsawg. Cov cuab yeej txiav tau hnav nrawm tshwj tsis yog tias tus nqi pub khoom noj, kev xa khoom txias, thiab cov cuab yeej geometry yog qhov sib txuam nrog cov khoom tshwj xeeb hardness thiab grain qauv.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua lub AMS 5387 nozzle lossis T800 chaw ncej cov menyuam pib nrog cov ntaub ntawv pov thawj raw cov ntaub ntawv pov thawj - tsis yog cov ntawv pov thawj zeb, tab sis ntau qib kev kho cua sov cov ntaub ntawv hla kev xa mus rau cov cav ntoo. Peb khiav spectrographic tsom xam ntawm txhua kauj lossis ingot. Yog tias cov ntsiab lus carbon drifts ± 0.02%, peb cais tawm thiab rov kuaj dua ua ntej thauj khoom rau hauv CNC lossis peev casting kab. Qhov no tsis yog overkill. Nws yog li cas peb tuav ± 0.005 hli tolerances ntawm 200 hli piston twj tso kua mis lub tog raj kheej vaj tse ua haujlwm ntawm 420 bar.
Peb txoj kev koom ua ke ntsug ua rau qhov sib txawv: casting, machining, thiab ua tiav nyob rau hauv ib lub ru tsev ISO. Tsis muaj kev sib koom tes txhais tau tias tsis muaj qhov sib txawv ntawm qhov ua tau zoo li-cam khwb cia thiab qhov kawg GD&T ua raws. Peb tshuab ncaj qha tawm ntawm ntsuab-xuab zeb los yog peev cam khwb cia blanks-tsis muaj lwm yam fixturing uas qhia txog kev ua yuam kev. Rau cov tsis-tus qauv geometries-xws li asymmetric winch center ncej chais nrog kev sib xyaw spline thiab bearing cov ntaub ntawv-peb siv 5-axis ib txhij milling nrog in-process laser probing los xyuas qhov contour fidelity ua ntej unclamping.
Qhov twg "Kev Cai" txhais tau tias kev koom tes hauv engineering - Tsis yog CAD txhais lus xwb
Qee cov tuam ntxhab kho cov kev cai txiav txim raws li kev sib txawv ntawm cov txheej txheem catalogs. Peb kho lawv raws li kev sib koom tes daws teeb meem. Thaum lub twj tso kua mis European OEM xa peb daim duab rau AMS 5387 ntsaws nrog peb qhov sib tshuam sab hauv radii thiab 0.8 µm Ra nto qhov yuav tsum tau ua tiav, peb cov lus nug thawj tsis yog "Koj puas tuaj yeem pom zoo cov lus hais?" Nws yog "Dab tsi yog hom kev ua tsis tiav uas koj tab tom sim tiv thaiv?"
Hloov tawm, cavitation yaig ntawm lub vojvoog hleb tau ua rau thaj chaw ua tsis tiav tom qab 1,200 teev. Yog li peb tau npaj ib lub zos tom qab tshuab electropolish-tsim los ntawm SEM imaging-kom tshem tawm cov kua muag tawm los ntawm cov pa sib tsoo. Peb kuj tau hais kom hloov cov kev kho cua sov ua ntu zus: kev daws teeb meem anneal * ua ntej * zaum kawg machining, ces laus * tom qab *, txhawm rau txhawm rau lub zog tensile yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Ib feem dhau 3,500-teev kev sim lub neej nrawm. Cov txiaj ntsig ntawd tau los ntawm kev nkag siab ntawm qhov tseem ceeb - tsis yog lub peev xwm xwb.
Qhov kev koom tes no ua haujlwm vim tias peb pab neeg suav nrog cov kws ua haujlwm hauv daim ntawv thov uas tau txhawb nqa hydraulic system tsim thoob plaws North America thiab Southeast Asia. Lawv hais GD&T txawj ntse. Lawv chij manufacturability txaus ntshai thaum ntxov-xws li qhia ib lub vojvoog 0.2 mm nyob rau hauv ib tug 12 mm tob dig qhov muag kab noj hniav qhov twg cov cuab yeej siv txwv nti khiav tawm. Peb tsis tos rau thawj qhov tsis lees paub los pib qhov kev sib tham.
Kev Tswj Xyuas Zoo Uas Tsis Nres ntawm CMM Daim Ntawv Qhia
Daim ntawv qhia CMM lees paub qhov ntev. Nws tsis paub meej txog kev ua haujlwm ncaj ncees. Yog li peb cov txheej txheem kev soj ntsuam mus tob dua: cov ntaub ntawv pov thawj tuaj, nyob rau hauv cov txheej txheem hardness mapping ntawm peb lub ntsiab lus ib casting, tag nrho-profile optical scanning ntawm qhov tseem ceeb sealing nto, thiab zaum kawg kev ua hauj lwm xeem - nrog rau siab lwj xyuas ntawm tag nrho cov valve lub cev mus txog 600 bar.
- Peb khaws tag nrho traceability: kub tooj, casting ntau, CNC program version, tus neeg teb xov tooj ID, thiab calibration cav rau txhua gage siv.
- Peb siv tau qhov chaw tiav nrog ob qho tib si profileometers thiab pom kev sib piv tawm tsam ASTM B487 tus qauv
- Peb ua cov tshuaj tsuag ntsev (ASTM B117) ntawm cov khoom tiav thaum corrosion kuj yog lub luag haujlwm tseem ceeb.
Tsis muaj batch ships yam tsis muaj daim ntawv soj ntsuam kos npe - thiab tsis muaj cov ntaub ntawv tshem tawm tshwj tsis yog tias txhua qhov chaw kuaj xyuas ua raws li cov kev lees paub ntawm cov neeg siv khoom tshwj xeeb, tsis yog qhov pib sab hauv.
Kev ntseeg tsis yog kev thov - Nws tau ntsuas hauv kev xa khoom sib xws
Txhim khu kev cai tsim khoom txhais tau tias tsoo lub sijhawm kawg yam tsis muaj kev txiav txim siab. Peb tau tswj xyuas> 97% raws sij hawm xa tuaj rau nruab nrab-ntim ntim ntau lawm dhau los 27 lub hlis dhau los - tsis yog los ntawm padding lub sij hawm, tab sis los ntawm embedding lean workflow coj mus rau hauv casting voj voog kev npaj, CNC teem caij, thiab kev kho cua sov queue tswj. Prototype txiav txim txav mus los ntawm kev mob siab rau engineering hlwb. Kev tsim khoom ua haujlwm ua rau cov khoom siv tsis siv neeg ntxiv cov lus ceeb toom khi rau cov khoom siv lead ua lub sijhawm. Tsis muaj "tus nqi nrawm" rau kev ua haujlwm ceev - tsuas yog kev sib tham ua lag luam pob tshab: "Peb tuaj yeem xa hauv 18 hnub yog tias peb kho lub sijhawm kho cua sov. lossis hauv 22 hnub nrog kev laus tag nrho ntawm AMS spec."
Saib tom ntej, peb tab tom nthuav dav R & D ntawm hybrid casting-machining txheej txheem-tshwj xeeb ze-net-zoo li peev casting ntawm nyuaj npib tsib xee raws alloy qhov chaw, ua raws li qhov tsawg kawg nkaus high-precision CNC Tshuag tshem tawm. Cov txiaj ntsig thaum ntxov qhia 32% cov khoom pov tseg tsawg dua thiab 20% nrawm dua rau cov khoom xws li ntau qhov chaw nres nkoj siab li qub. Peb lub hom phiaj tsis yog kom ua tau raws li niaj hnub specs. Nws yog los pab cov neeg siv khoom tsim cov kab ke tag kis nrog kev ua siab ntev, siab dua, thiab kev pabcuam ntev dua.
Yog tias koj qhov project tom ntej no suav nrog cov khoom siv nickel-tshwj xeeb tshaj yog AMS 5387, T800, lossis lwm yam kev ua tau zoo cobalt-nickel qib-pib nrog cov khoom siv, tsis yog kos duab xwb. Xaiv tus khub uas nws cov txheej txheem tswj hwm raws li koj qhov kev xav tau. Xaiv qhov kev ntseeg tau ua rau txhua kauj ruam-tsis tau cog lus hauv daim ntawv muag.
