Thaum engineers qhia a poob ciab casting qhov chaw Hoobkas, lawv tsis yog tsuas yog xaj hlau - lawv xav tau qhov kev ruaj ntseg nyob rau hauv 300 MPa siab, microstructure kev ncaj ncees tom qab cua sov caij tsheb kauj vab, thiab nto tiav uas muaj sia nyob abrasive slurry ntws rau 12,000+ teev ua haujlwm. Qhov ntawd yog lub hauv paus - tsis yog qhov zam.
Peb tau pom ntau txoj haujlwm ua tsis tiav ntawm qhov sib cuam tshuam ntawm kev tsim qauv thiab kev ua haujlwm zoo. Ib tug cobalt alloy nozzle tawg thaum lub sij hawm thermal shock kuaj. Lub piston twj tso kua mis lub tog raj kheej nyob warps tom qab nitriding. Lub winch center ncej cov menyuam qhia tau hais tias hnav ntxov ntxov txawm tias ntsib nominal hardness specs. Cov no tsis yog cov khoom ua tsis tiav. Lawv yog cov txheej txheem misalignments - qhov twg casting shrinkage tsis them nyiaj rau hauv machining Tshuag, qhov twg grain flow directions contradicts load paths, los yog qhov chaw soj ntsuam nres ntawm qhov ntev thiab tsis quav ntsej metallurgical traceability.
Yog vim li cas poob wax casting qhov chaw Hoobkas xaiv pib nrog alloy cwj pwm - tsis yog geometry
Poob wax casting (kev nqis peev casting) ua tau zoo rau cov khoom siv, ze-net-zoo li-tab sis tsuas yog thaum lub Hoobkas kho metallurgy li engineering, tsis yog kev tsim khoom. Siv AMS 5387 cobalt alloy: nws cov ntsiab lus siab chromium thiab tungsten muab kev tiv thaiv corrosion, tab sis kuj ua haujlwm hnyav. Lub khw uas tshuab nws zoo li 304 stainless yuav hlawv cov cuab yeej, distort qhov chaw, thiab tawm subsurface puas tsuaj uas pib qaug zog tawg.
Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua yam khoom siv cobalt-nickel pib nrog cov neeg muag khoom-tso ntawv pov thawj T800 alloy ingots-tsis yog "CoCr" billets. Cov ntaub ntawv pov thawj raw khoom suav nrog tag nrho spectrographic tsom xam, kev txheeb xyuas qhov loj ntawm ASTM E112, thiab batch-theem tensile cov ntaub ntawv. Peb tsis lees txais cov ntaub ntawv kuaj xyuas zeb-peb txheeb xyuas lawv. Cov khoom lag luam tau dhau los kuaj ultrasonic rau kev tsis sib txuas sab hauv ua ntej peev pwm sib dhos txawm pib.
Qhov kev qhuab qhia no cais qhov muaj peev xwm tiag tiag los ntawm daim ntawv thov. Koj yuav pom cov chaw tsim khoom hais tias "AMS 5387 ua raws" thaum siv cov khoom noj tsis zoo lossis hla kev daws teeb meem annealing. Qhov tshwm sim tiag tiag hauv ntiaj teb? Ib qho North American hydraulic OEM tau tshaj tawm 22% kev ua haujlwm tsis ua haujlwm ntawm lub twj tso kua mis kom txog thaum hloov mus rau tus khub uas tau tswj hwm cov txheej txheem kev kho cua sov ua ntej-thiab tau sau tseg txhua lub sijhawm so, tus nqi nce, thiab cov cua sov nyeem ntawv.
Vertical kev koom ua ke tsis yog hais txog kev yooj yim - nws yog hais txog kev tswj cov kev sib tshuam tseem ceeb
Feem ntau "ib-stop-khw" foundries outsource machining. Feem ntau cov khw CNC tsis kam castings nrog> 0.5 hli cua ntsawj ntshab lossis phab ntsa tuab tsis sib xws. Qhov sib txawv ntawm qhov casting thiab qhov kawg yog qhov twg precision tuag.
QINGDAO QIANGSENYUAN ua haujlwm ob qho tib si peev casting kab thiab multi-axis CNC hlwb nyob rau hauv ib lub ru tsev ISO 9001. Qhov no txhais tau hais tias tib tus kws tshaj lij uas lees paub koj daim duab GD&T kuj tseem ua haujlwm rau 5-axis zeb uas ua tiav lub rooj zaum valve-thiab kho cov cuab yeej siv raws li cov ntaub ntawv pov thawj CMM los ntawm ntau dhau los. Tsis muaj handoffs. Tsis muaj kev xav. Tsis muaj qhov xav tsis thoob.
Piv txwv li: lub siab valve lub cev yuav tsum ± 0.025 hli roundness ntawm 120 hli bore, nto roughness Ra ≤ 0.4 µm, thiab rooj plaub qhov tob ntawm 0.8-1.2 hli tom qab carburizing. Peb cov haujlwm ua haujlwm kaw qhov ntu no: peev nrum → kev ntxhov siab → CNC ntxhib / tiav → kho cua sov → tom qab tshav kub kho kev sib tsoo → kho qhov muag pom kev. Txhua kauj ruam pub cov ntaub ntawv pov thawj mus rau tom ntej. Yog tias qhov ntsuas qhov ntsuas qhov ntsuas + 0.18 hli loj, peb txo qis roughing Tshuag - tsis hla kev ua tiav.
- CNC-machined qhov chaw: Los ntawm txhuas prototypes rau hardened steel sib dhos
- Cobalt-nickel alloy Cheebtsam: AMS 5387, T800, thiab kev cai sib txawv nrog tag nrho traceability
- Hlau castings: EN-GJS-400-15 cov hlau nplaum rau cov ntawv thov siab
- Hlau & stainless hlau castings: AISI 4140, 17-4PH, thiab super duplex qib
Kev ua tau zoo tsis raug tshuaj xyuas hauv - nws tau tsim hauv, ntsuas tawm, thiab taug qab rov qab
"Peb tshuaj xyuas 100%" txhais tau tias tsis muaj dab tsi tsis muaj ntsiab lus. Qhov ntsuas yog dab tsi? Nrog dab tsi instrument? Tawm tsam tus qauv twg? Los ntawm leej twg?
Nov yog qhov tshwm sim ntawm ntau yam ntawm cobalt alloy nozzles:
• Cov khoom xa tuaj: Spectrometer + hardness + macroetch pov thawj
• Pre-pwm: Ciab qauv CMM scan tiv thaiv CAD, nrog rau qhov chaw ntawm qhov rooj
• Tom qab-cam khwb cia: tag nrho-ib CMM nrog kub-compensated sojntsuam, ntxiv rau dye penetrant ib ASTM E165
• Tom qab-machining: Optical profileometer rau sealing nto, tswj kev ntsuas ntawm tag nrho cov GD&T callouts
• Thaum kawg: Kev ntsuas siab ua haujlwm ntawm 1.5 × kev ua haujlwm siab, kev tshuaj xyuas qhov pom hauv qab 10 × magnification, tag nrho cov ntaub ntawv qhia txog kev sib txuas ntawm tus lej serial rau yaj batch, kub kho cav, thiab cov ntaub ntawv tshuaj xyuas
Tsis muaj shortcuts. Tsis muaj "sampling." Tsis muaj ntaub ntawv rov ua dua. Txhua lub ntsiab lus tseem ceeb yog QR code txuas mus rau nws cov ntaub ntawv ntxaib digital.
Tus nqi tiag tiag ntawm kev xaiv tsis raug - thiab yog vim li cas nws yeej tsis yog tus nqi xwb
Ib qho poob ciab casting qhov chaw Hoobkas quoting 18% qis tshaj li qhov nruab nrab ntawm kev ua lag luam feem ntau ua tiav los ntawm kev txiav cov ces kaum koj yuav tsis pom kom txog thaum qhov tsis ua hauj lwm: hla kev txheeb xyuas qhov loj me, siv cov cuab yeej siv dav siv tsis siv cov hlau tshwj xeeb txau / nrawm, lossis lees txais ± 0.2 hli qhov sib txawv ntawm cov yam ntxwv xav tau ± 0.05 hli.
Ib lub tuam txhab lag luam Esxias sab hnub tuaj tau txuag tau $ 3.20 rau ib chav tsev ntawm lub tog raj kheej vaj tse - tom qab ntawd tshwm sim $ 218,000 hauv kev hloov pauv tom qab 40% ua tsis tiav hauv 3 lub hlis. Hauv paus ua rau? Kev tsis sib haum ntawm carbide dispersion nyob rau hauv cobalt matrix, undetected vim hais tias tus neeg muag khoom tsis ua metallographic cross-section ntawm ntau lawm.
Tus nqi tiag tiag los ntawm kev sib koom ua haujlwm nruj-tsis yog tus nqi qis tshaj. Nws txhais tau tias koj qhov kev tshuaj xyuas tsim suav nrog cov lus qhia zoo li: "Lub vojvoog 0.8 hli no tsim qhov kub ntawm lub sijhawm centrifugal casting - pom zoo kom nce mus rau 1.2 hli thiab kho qhov rooj kom tswj tau cov kev taw qhia solidification." Lossis: "Koj qhov Rab Ra 0.2 µm ntawm lub 30 ° conical lub rooj zaum no yuav tsum tau tig pob zeb diamond-tsis yog milling-uas ntxiv 12% tus nqi tab sis txuas lub neej kev pab cuam los ntawm 3.7 ×."
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsis muag castings. Nws muab lub luag haujlwm tseem ceeb ntawm cov khoom siv hlau uas tsim los rau kev ua haujlwm, siv tau rau kev ua tau zoo, thiab traceable rau yaj. Thaum koj daim ntawv thov xav tau ntau dua "nws haum," koj xav tau ib qho poob ciab casting qhov chaw Hoobkas uas kho txhua feem zoo li nws tab tom khiav koj qhov tseem ceeb tshaj plaws-vim nws yog.
