Thaum cov kws tshaj lij qhia cov khoom siv hlau rau cov hydraulic li qub, lub twj tso kua mis, lossis cov khoom siv winch-cov khoom uas yuav tsum muaj sia nyob 300-bar siab cycles lossis abrasive sand-laden oil flow-lawv tsis yog xav tau tus neeg muag khoom xwb. Lawv xav tau ib tus khub uas tau pom tib qhov tawg tawm hauv AMS 5387 cobalt alloy nozzle ntawm 450 ° C. Leej twg tau ntsuas microstructural drift hla tsib lub tshav kub ntawm T800-raws li cov khoom. Leej twg paub raws nraim qhov twg xuab zeb casting porosity hides - thiab yuav ua li cas CNC tiav machining tuaj yeem nthuav tawm nws ua ntej kev soj ntsuam zaum kawg.
Tias yog vim li cas thoob ntiaj teb OEMs hauv North America thiab Europe tsis tu ncua rov qab mus rau ib qho cam khwb cia hlau qhov chaw Hoobkas rooted tsis nyob rau hauv ntim, tab sis nyob rau hauv pov thawj: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Headquartered hauv Qingdao, qhov no tsis yog lub hom phiaj dav dav. Nws yog lub chaw tsim khoom raug tsim los ntawm peb qhov tsis sib tham - qhov ntev ntawm qhov rov ua haujlwm nyob rau hauv ± 0.015 hli ntawm qhov tseem ceeb bores, metallurgical sib xws nyob rau hauv batch, thiab tag nrho traceability los ntawm raw daim ntawv pov thawj daim ntawv pov thawj CMM kawg.
Lawv lub zog pib nrog kev qhuab ntuas cov khoom. Cobalt-nickel alloys zoo li AMS 5387 tsis machined-lawv tau coaxed. Thermal expansion mismatches ntawm cov cuab yeej thiab workpiece, ua hauj lwm-hardening tus nqi siab tshaj 300%, thiab carbide segregation tag nrho cov xav tau ntawm lub sij hawm hloov. QINGDAO QIANGSENYUAN tsis outsource kev kho cua sov los yog cia siab rau generic tsum ntaub ntawv nplooj ntawv. Hloov chaw, lawv sib koom ua ke tsim thermal voj voog nrog cov neeg muag khoom muaj ntawv pov thawj, siv tau txhua qhov tuaj tawm tsam ASTM E112 grain loj thiab ASTM E381 macrostructure qauv, thiab khaws tag nrho batch-theem traceability - suav nrog yaj naj npawb, ncuav hnub, thiab cov cav tov cua sov. Thaum tus neeg siv khoom nug txog "T800-sib npaug," cov lus teb tsis yog daim ntawv teev cov ntaub ntawv - nws yog cov ntaub ntawv sib piv ntawm cov ntaub ntawv tawv tawv, kev cuam tshuam kev cuam tshuam ntawm ASTM G28, thiab nkag mus rau lub neej ntawm 650 ° C.
Qhov kev nruj no txuas mus rau kev sib koom ua ke. Cov neeg muag khoom feem ntau cais casting thiab machining. QINGDAO QIANGSENYUAN koom ua ke lawv txhob txwm tshaj tawm. Sand-cam khwb cia hlau vaj tse nyob rau hauv kev ntxhov siab-relieving * ua ntej * ntxhib CNC milling - tsis yog tom qab -vim residual stresses distort bore geometry thaum kawg tig. Kev nqis peev-cam khwb cia cobalt nozzles tau ze-net-puab casting nrog 0.3 hli nyiaj tso nyiaj, tom qab ntawd txav ncaj qha mus rau 5-axis machining nrog coolant-los ntawm spindles thiab in-probing. Tsis muaj handoffs. Tsis muaj qhov me me drift ntawm kev ua haujlwm. Tsis muaj rework loops. Lawv qhov chaw ISO-raws li kho qhov kev poob qis, machining deflection, thiab thermal loj hlob raws li kev sib txuas sib txawv - tsis yog cov kauj ruam cais. Qhov ntawd yog li cas lawv tuav txoj haujlwm muaj tseeb ntawm GD&T callouts zoo li kev ua haujlwm siab ntev Ø0.05 hli ntawm MMC hla 12 datum nta ntawm ib lub piston twj tso kua mis lub tog raj kheej vaj tsev.
Kev ntseeg tau tshwm sim hauv kev xa khoom - tsis yog specs xwb. Cov neeg siv khoom tau tshaj tawm cov sijhawm ua haujlwm zoo ib yam ntawm cov xaj nruab nrab (50-500 pcs) vim tias kev npaj tsim khoom siv lean workflow mapping, tsis yog daim ntawv kwv yees. Thaum lub tuam txhab European twj tso kua mis xav tau 87 kev cai AMS 5387 lub rooj zaum valve nrog 17 qhov tshwj xeeb geometries, pab pawg tau ua haujlwm ib txhij: kev lees paub GD&T kev txhais lus hauv 48 teev, chij ntu nyias-walled feem ntau cuam tshuam rau lub sijhawm daws teeb meem annealing, thiab tawm tswv yim kev hloov kho gating tsim uas txiav casting tsis lees paub los ntawm 62%. Tsis muaj "tsim khov" ncua. Tsis muaj kev txiav txim zaum kawg. Tsuas yog qhov ua haujlwm tau zoo, raws sijhawm, nrog cov ntaub ntawv tshuaj xyuas tag nrho - suav nrog cov duab kos duab kho qhov muag overlaid ntawm nominal CAD rau kev pom kev sib txawv ntawm qhov pom.
Saib tom ntej, qhov tsom xam sharpens-tsis broadens. Lawv tab tom nqis peev R & D rau hauv hybrid casting-machining workflows rau high-alloy Cheebtsam uas cov txheej txheem tsoos tsoos txwv: xav tias centrifugally cam khwb cia stainless lub tes tsho nrog kev sib xyaw ua ke hauv cov cua txias, ua tiav hauv ib qho kev teeb tsa siv zeb-tig chaw. Daim ntawv pov thawj nthuav dav lub hom phiaj ntawm cov kev cai tshwj xeeb-ASME B16.34 rau lub cev valve, API 6A rau cov khoom siv hauv lub taub hau, EN 15085 rau kev siv tsheb ciav hlau-tsis yog ISO 9001. Tab sis cov tub ntxhais tseem tsis hloov pauv: a cam khwb cia hlau qhov chaw Hoobkas uas ntsuas kev vam meej tsis nyob rau hauv tons poured, tab sis nyob rau hauv xoom teb tsis ua hauj lwm nyob rau hauv lub siab-tseem ceeb lub rooj sib txoos. Vim hais tias nyob rau hauv hydraulic systems thiab oilfield twj, kev ntseeg siab tsis yog ib tug feature. Nws tsuas yog specifications uas tseem ceeb.
