Thaum muab khoom kev tsim kho machinery qhov chaw Hoobkas cov neeg koom tes rau OEM muab khoom, engineers thiab procurement managers ntsib ib tug nqaim margin rau qhov yuam kev. Ib lub tsev nyob ib leeg nrog 0.02 hli qhov dav dav tuaj yeem ua rau hydraulic system tsis ua haujlwm hauv qab 350-bar siab. Lub winch center ncej cov menyuam ua los ntawm T800 cobalt alloy tsis sib haum yuav qaug zog tom qab 12,000 cycles - tsis yog 50,000 teev. Peb tau pom peb North American OEMs ncua cov khoom lag luam xa tawm vim tias qhov porosity casting mus tsis tau kuaj kom txog thaum kawg ua haujlwm. Qhov ntawd tsis yog qhov teeb meem zoo - nws yog txoj kev pom kev sib txawv.
Lub ntiaj teb no precision pib ua ntej thawj txiav
Kev ntseeg tiag tiag hauv cov khoom siv hauv kev tsim kho tsis yog tsim los ntawm kev tshuaj xyuas - nws tau kos thaum xaiv cov khoom siv thiab ua kom muaj zog hauv keeb kwm thermal. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., txhua qhov AMS 5387 cobalt alloy twj tso kua mis pib nrog ntawv pov thawj billet traceability: kub tooj, yaj tsom xam, thiab cov neeg muag khoom soj ntsuam cov ntaub ntawv sau ua ntej raw khoom clears lub warehouse rooj vag. Tsis muaj kev zam. Peb tau sim 17 tus neeg muag khoom cobalt-nickel tshaj li 8 xyoo-tsuas yog 4 ua tau raws li peb cov qauv microstructure zoo sib xws rau cov nplej loj faib thiab carbide dispersion. Qhov kev lim dej no ib leeg tshem tawm 63% ntawm cov peev txheej hauv kev pabcuam tawg hauv cov hnab looj tes siab.
Lawv qhov chaw ua raws ISO ua haujlwm ua haujlwm sib luag thiab ua haujlwm ua haujlwm - tsis yog kev sib txuas ua ke. Xuab zeb-cam khwb cia hlau twj tso kua mis hauv paus muaj kev ntxhov siab-relieving tshav kub kho * ua ntej * CNC teeb, tsis yog tom qab. Vim li cas? Vim tias residual stress redistribution thaum lub sij hawm machining ua rau 0.05-0.12 hli warpage nyob rau hauv nyias phab ntsa vaj tse. Lawv tsib-axis machining chaw tuav ± 0.005 hli txoj hauj lwm kam rau ua ntawm 120-mm-inch cylinder bores - txheeb xyuas qhov nruab nrab txheej txheem nrog Renishaw PH10M probes, tsis yog thaum kawg CMM check. Qhov ntawd yog li cas piston twj tso kua mis ua tiav <1.2 µm Ra nto tiav ntawm qhov tseem ceeb sealing av yam tsis muaj lwm yam lapping.
Vim li cas "kev koom ua ke" tsis yog kev lag luam fluff - nws yog kev pov hwm qhov ntev
Qee qhov chaw ua haujlwm tawm ntawm qhov chaw casting, lwm qhov kev cog lus ua tiav. QINGDAO QIANGSENYUAN tus tswv tag nrho cov saw: peev casting rau cobalt alloy plugs, xuab zeb casting rau structural steel thav duab, multi-axis CNC rau siab valve lub cev, thiab tswj cua kub kev kho mob rau T800 ncej rollers. Qhov kev tswj ntsug no muab peb qhov txiaj ntsig ntsuas tau:
- Microstructure kev ncaj ncees: Cov kev kho cua sov tsis yog hloov mus rau qhov tseeb casting ntau-tsis yog cov nkhaus nkhaus. Hardness variation hla 400-mm-ntev winch ncej nyob hauv ± 2 HRC, tsis yog ± 8 HRC.
- Dimensional stability: Machining fixtures siv cam khwb cia datum nto-tsis theoretical CAD cov ntsiab lus. Qhov tshwm sim: 92% thawj-dhau GD&T ua raws li cov twj tso kua mis sib dhos nrog 14+ qhov tseeb-txoj hauj lwm callouts.
- Deg muaj nuj nqi alignment: Kev txhaj tshuaj peening siv tau raug kho raws li qhov chaw raug-sau lub ntsej muag tau txais kev ntxhov siab compressive profiles optimized rau qaug zog tiv thaiv; bearing journals tau txais cov profile tuned rau roj tuav.
Peb ib zaug tshuaj xyuas cov duab kos rau ntawm ntug dej hiav txwv drilling twj tso kua mis qhov twg GD&T pawg-ups tsim 0.18 hli cumulative kam rau ua. Lawv pab pawg engineering tau tshaj tawm nws hauv 48 teev - tsis yog "tsis ua tau," tab sis nrog kev hloov kho cov tswv yim thiab cov txheej txheem machining hauv cheeb tsam uas txiav kev pheej hmoo los ntawm 76%. Qhov ntawd tsis yog kev sib tham. Nws yog co-engineering.
Qhov twg feem ntau cov chaw ua haujlwm tsis ua haujlwm - thiab yuav ua li cas precision casting hloov tus lej
Qee tus neeg yuav khoom xav tias tag nrho cov castings sib npaug yog tias lawv ua tau raws li ASTM A494 lossis EN 1559. Tsis yog. Cobalt alloy nozzles xav tau kev taw qhia kom ruaj khov kom tsis txhob muaj qhov chaw nruab nrab. Hlau castings rau excavator boom mounts xav tau nodular graphite tis txheeb xyuas los ntawm cov duab tsom xam - tsis yog cov ntaub ntawv qhia lub zog tensile. QINGDAO QIANGSENYUAN cov xuab zeb casting kab siv lub sij hawm ntawm metallographic sampling: txhua 5th ncuav tau sai-sectioned, etched, thiab imaged. Grain qauv maps pub rov qab rau hauv qhov cub kub algorithms hauv 90 feeb.
Tias yog vim li cas lawv tsis yog tus qauv T800 cov khoom xa rov qab hnav tsis kam - txawm tias cov neeg siv khoom hloov geometry nruab nrab khiav. Ib tus neeg Esxias sab hnub tuaj tau rov tsim dua lub tsev hydraulic lub cev muaj zog ob zaug thaum lub sijhawm ua qauv. Txhua qhov kev hloov kho xa tawm hauv 11 hnub, nrog cov hardness gradients zoo tib yam (42–48 HRC) thiab carbide ntim feem (18.3–18.7%) hla tag nrho peb ntau. Tsis xav tau kev tsim nyog.
Kev ntseeg tau koj tuaj yeem txheeb xyuas - tsis yog cog lus xwb
Txhua qhov khoom xa tuaj suav nrog ntau tshaj li daim ntawv pov thawj ntawm kev ua raws. Nws nqa:
- Tag nrho cov ntaub ntawv traceability mus rau ladle kub tooj thiab spectrographic tsom xam
- CMM soj ntsuam cov ntaub ntawv nrog qhov tseeb vs. nominal qhov tseem ceeb rau tag nrho GD&T nta
- Nto tiav pov thawj los ntawm kev nyeem ntawv profileometer portable - tsis yog "Ra <0.8 µm” kev thov
- Cov ntaub ntawv ntsuas kev ua haujlwm uas muaj feem xyuam: qhov siab lwj rau cov li qub, torque-rau-tsis ua haujlwm rau kev sib dhos
Qhov no tsis yog overhead. Nws yog qhov sib txawv ntawm kev ntes 0.03 hli bore taper yuam kev ua ntej sib dhos-los yog nrhiav tau nws thaum lub sijhawm ua haujlwm ntawm $ 1,200 / teev tus nqi qis. Lawv cov txheej txheem kev npaj lean taug qab WIP los ntawm kev txiav txim, tsis yog batch, yog li cov khoom ntim nruab nrab tswj hwm ± 3-hnub xa khoom qhov rais - txawm tias muaj 70% cov ntsiab lus geometry.
Rau OEMs tsim hydraulic systems, engineering tsheb, los yog oilfield twj, lub kev tsim kho machinery qhov chaw Hoobkas kev xaiv tsis yog hais txog nqe lus qis tshaj. Nws yog hais txog leej twg tuav lub metallurgical, geometric, thiab kev ua haujlwm xov nruj txaus uas koj cov khoom kawg ua tau zoo - lub voj voog tom qab lub voj voog, lub caij tom qab lub caij. QINGDAO QIANGSENYUAN TECHNOLOGY tsis yog muab khoom xwb. Lawv muab kev kwv yees.
