Lub peev casting Hoobkas tsis yog ib qho chaw nrog rauv taws thiab pwm. Nws yog qhov twg precision pib ua ntej hlau melts - qhov twg ib tug siv quav ciab qauv, tsis thicker tshaj ib tug ntiv tes, txhais cov geometry zaum kawg ntawm lub twj tso kua mis vaj tse uas yuav tsum tau kaw ntawm 400 bar los yog cobalt alloy nozzle tiv thaiv 800 ° C thermal yaig. Rau txhais peev casting Hoobkas yog piav qhia txog kev tswj xyuas nruj me ntsis: cov ntaub ntawv tshawb fawb tau ua raws li kev ntsuas ntsuas, metallurgy cuam tshuam nrog GD&T ua raws, thiab txhua lub voj voog kho cua sov yog traceable rau nws cov pob zeb nyoos.
Peb tau pom cov neeg siv khoom nkoj kos duab kos npe "ASME B16.34, Chav Kawm 900" tsuas yog nrhiav tau - tom qab thawj tsab xov xwm tshuaj xyuas - tias lawv cov chaw tsim khoom xaiv tsis muaj ntawv pov thawj AMS 5387 cobalt alloy yaj cav lossis CMM-muaj peev xwm ua pov thawj hauv txheej txheem. Qhov kev sib txawv ntawd cais lub rooj cob qhia los ntawm qhov tseeb peev casting Hoobkas. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua qhov kev txiav txim raws li lub voj kaw: tsim kev tshuaj xyuas → cov ntaub ntawv pov thawj → wax qauv validation → plhaub tsim tswj → dewaxing ramp profiling → cub cua sov xyuas → post-cam khwb cia microstructure tsom xam → CNC tiav machining muaj nuj nqi. Tsis muaj kauj ruam yog outsourced. Tsis muaj batch lacks tag nrho traceability.
Vim li cas theem ntawm kev sib koom ua ke tseem ceeb? Vim tias kev nqis peev casting tsis ua ntsiag to - tsis yog nyob rau hauv cov txiaj ntsig, tab sis hauv kev pabcuam lub neej. Qhov sib txawv ntawm 0.05 hli nyob rau hauv lub piston twj tso kua mis lub tog raj kheej lub tog raj kheej yog tsis pom nyob rau hauv ib tug luam. Tab sis nyob rau hauv cyclic hydraulic load, nws accelerates lub nplhaib hnav, tsub kom 17%, thiab txiav kev pab cuam lub sij hawm ntawm 12,000 mus rau 7,200 teev. Peb ntes tau qhov no thaum lub sij hawm sib koom ua tsis tiav-hom tshuaj xyuas nrog European engineering tsheb OEM. Lawv cov neeg muag khoom ua ntej tau siv cov khoom noj "stainless steel" - tsis muaj cov ntaub ntawv kho cua sov, tsis muaj kev kuaj kev sib tsoo. Peb pab pawg tau teev tseg ASTM A494 CW6MC, txheeb xyuas qhov loj ntawm ASTM E112, thiab ntxiv cov tshuaj annealing + quenching nrog nitrogen ntxuav. Qhov tshwm sim: xoom teb tsis ua haujlwm thoob plaws 18 lub hlis thiab 42,000 units.
Lub tuam txhab kev nqis peev tiag tiag kuj muaj nws cov kev txwv - thiab sib txuas lus rau lawv thaum ntxov. Qee qhov xav tias "cov duab geometry nyuaj = tsis siv neeg haum rau kev nqis peev casting." Tsis muaj tseeb. Undercuts tob dua 3 × phab ntsa thickness? Yuav tsum tau ceramic cores - ntxiv cov nqi thiab lub sijhawm ua haujlwm. Phab ntsa thickness hauv qab 2.5 hli hauv T800 cobalt alloy? Kev pheej hmoo ntawm microporosity tshwj tsis yog lub plhaub ziab lub sij hawm, dewax tus nqi, thiab lub ncuav kub yog kho li ntawm ± 2 ° C. Peb chij cov no thaum kuaj xyuas - tsis yog tom qab pwm tso tawm. Peb cov engineers tsis hais tias "peb tuaj yeem ua tau." Lawv hais tias: "Peb tuaj yeem tuav ± 0.03 hli ntawm lub ntsej muag flange yog tias koj tso cai 1.2 hli cov qauv ntawm sab hauv tav, thiab peb yuav txheeb xyuas ntawm optical contour scan pre-machining." Qhov tshwj xeeb ntawd los ntawm kev khiav 14,000+ peev cam khwb cia ntau txij li xyoo 2015 - tsis yog los ntawm phau ntawv teev npe.
Dab tsi teev QINGDAO QIANGSENYUAN sib nrug tsis yog qhov ntsuas. Nws yog tsom. Peb tsis muab automotive brackets los yog kho kom zoo nkauj kho vajtse. Txhua feem peb tsim ua haujlwm rau ib qho ntawm plaub qhov tseem ceeb: high-pressure hydraulic li qub, roj & roj downhole cov cuab yeej, engineered twj tso kua mis, los yog cov khoom siv mobile winch systems. Qhov kev nqaim ntawd cia peb txhim kho txhua yam-cov cuab yeej cuab tam cov tsev qiv ntawv rau ntau qhov chaw nres nkoj geometries, ua ntej tsim nyog T800 alloy cov chaw muag khoom nrog zeb-test cov ntaub ntawv archived rau 10 xyoo, CNC cov kev pab cuam validated ntawm tiag tiag cam khwb cia nto (tsis zoo tagnrho CAD qauv), thiab soj ntsuam cov kev npaj ua nyob ib ncig ntawm kev ua tau zoo-tsis yog qhov seem dhau/fab. Thaum tus neeg siv khoom nug, "Koj puas tuaj yeem pov qhov tsis yog qhov chaw nruab nrab ntawm cov menyuam nrog cuam tshuam spline thiab asymmetric txias raws?" peb teb nrog daim ntawv qhia txheej txheem-tsis yog daim ntawv tsocai.
Los txhais cov peev casting Hoobkas yog kom paub txog nws raws li ib tug convergence point: metallurgical kev qhuab qhia, geometric txawj ntse, thiab ua hauj lwm nruj. Nws yog qhov "cov ntaub ntawv pov thawj" txhais tau tias koj tuav lub log log, spectrographic daim ntawv qhia, thiab tensile nkhaus - tsis yog ib lub thwj. Qhov twg "precision" txhais tau tias CMM cov ntaub ntawv nkag rau txhua qhov tseem ceeb, tsis yog thawj kab lus. Qhov twg "kev ntseeg tau" pib nrog lub plhaub viscosity tswj-tsis nrog lub ntim zaum kawg. Yog tias koj daim ntawv thov xav kom muaj kev ncaj ncees nyob rau hauv lub siab heev, kub, los yog corrosion, hla tus generalist. Xaiv ib tus khub uas kho txhua qhov kev ua haujlwm zoo li lub luag haujlwm tseem ceeb hauv lub luag haujlwm-vim hauv cov tshuab hydraulic, cov cuab yeej siv roj av, thiab cov twj tso kua mis siab, nws yog.
