Thaum cov kws tshaj lij qhia cov tuam txhab kev pabcuam steel ua haujlwm rau lub hom phiaj tseem ceeb hydraulic li qub lossis cov twj tso kua mis siab, lawv tsis yog yuav cov khoom xwb-lawv tab tom yuav qhov kev ruaj ntseg nyob rau hauv thermal cycling, microstructural sib xws thoob plaws 500-unit batches, thiab xoom kam rau porosity hauv load-bearing flanges. Tias yog vim li cas precision tsis yog kev lag luam thov ntawm no - nws yog lub hauv paus.
Lub Hoobkas muaj tseeb steel casting kev pabcuam ua haujlwm tag nrho physics ntawm solidification: nucleation tswj thaum lub sij hawm ncuav, kev taw qhia txias kom suppress shrinkage kab noj hniav, thiab tom qab cam khwb cia kev nyuaj siab nyem uas tiv thaiv GD & T drift thaum kawg machining. Peb tau pom cov neeg siv khoom tsis lees paub tag nrho - tsis yog vim qhov loj me tsis muaj qhov tshwj xeeb, tab sis vim tias cov nplej ntws tawm kev cuam tshuam cuam tshuam lub neej qaug zog hauv lub piston twj tso kua mis lub tog raj kheej ua haujlwm ntawm 3,000 psi cycles. Qhov ntawd yog qhov muaj peev xwm cais cov neeg muag khoom los ntawm cov neeg koom tes.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm ISO-raws li chaw nyob hauv Qingdao qhov chaw xuab zeb casting thiab peev casting tsis yog cov txheej txheem ib leeg-lawv tau ntsuas tawm tsam CNC machining cov txiaj ntsig. Thaum tus neeg siv khoom xa daim duab kos rau AMS 5387 cobalt alloy 6 lub twj tso kua mis, peb pab pawg tau teeb tsa kev kho cua sov nkhaus * ua ntej * pwm tsim pib. Vim li cas? Vim T800-raws li alloys nthuav 12% ntau tshaj 316 stainless thaum lub sij hawm kev daws annealing - thiab yog tias koj tsis them nyiaj rau hauv tus qauv, koj CMM daim ntawv qhia yuav qhia zoo meej geometry ntawm daim ntawv thiab ua hauj lwm tsis ua hauj lwm nyob rau hauv lub tshav pob.
Tsis yog tag nrho cov hlau castings muaj sia nyob hauv lub ntiaj teb tiag tiag. Nov yog qhov peb txheeb xyuas-txhua lub sijhawm:
Qee cov neeg muag khoom hais txog steel casting kev pabcuam Hoobkas nqi raws li qhov hnyav ib leeg. Qhov ntawd ua tsis tiav thaum koj feem yog qhov tsis yog-tus qauv cobalt alloy nozzle nrog 0.05 hli phab ntsa tuab hauv 45 ° conical seem. Cov phab ntsa nyias nyias txias sai heev, ua rau micro-shrinkage; tuab flanges txias qeeb heev, tsim kom muaj kev ntxhov siab. Peb qhov kev daws teeb meem? Zoned pwm cua txias raws tswj los ntawm PLC-tswj dej ntws-tshuaj ntsuam xyuas nrog infrared thermography thaum sim nchuav.
Peb tau xa ntau dua 2,300 qhov tshwj xeeb hlau thiab stainless hlau castings txij li xyoo 2019 - tsis muaj qhov xav tau rov ua haujlwm vim qhov tsis sib xws ntawm metallurgical. Yuav ua li cas? Peb koom nrog cov khoom siv raw nrog peb cov ntawv pov thawj mills, khiav cov kev soj ntsuam peb lub hlis twg ntawm cov cua sov tuaj, thiab tuav cov ntaub ntawv pov thawj cov ntaub ntawv uas sib txawv ntawm cov pa roj carbon sib npaug nrog kev kwv yees machinability Performance index. Thaum ib lub European OEM xav tau 120 units ntawm stainless hlau siab valve nrog ≤0.02 hli txoj hauj lwm kam rau ua ntawm rau threaded ports, peb siv cov ntaub ntawv no los xaiv ib tug tsawg-carbon 17-4PH variant nrog optimized leej faj cov ntsiab lus - txiav cov cuab yeej hnav los ntawm 40% thiab tuav GD&T nruj dua lawv cov thawj spec tso cai.
"Kev xa khoom raws sijhawm" txhais tau tias tsis muaj dab tsi yog tias thawj 10 units ua tsis tiav kev sim ua haujlwm. Peb qhov kev npaj tsim khoom ua ke nrog cov rooj vag zoo - tsis yog qhov tseem ceeb xwb. Txhua qhov kev txiav txim dhau los ntawm plaub qhov chaw kuaj xyuas: kos duab validation (GD&T feasibility), cov ntaub ntawv tso tawm (suab tooj cua sov), in-process CMM scan (tom qab machining ntxhib), thiab zaum kawg soj ntsuam (dimensional + functional + pom). Peb khaws tag nrho cov traceability: yog tias tus neeg siv khoom chij qhov teeb meem, peb rub qhov tseeb CNC program version, kho cua sov cav, thiab tus neeg teb xov tooj ID hauv 90 feeb.
Qhov kev qhuab qhia no tso cai rau peb txhawb nqa ob qho tib si prototyping sai - xa cov tshuab sib dhos thiab cam khwb cia hauv 18 hnub ua haujlwm - thiab ruaj khov nruab nrab-ntim khiav. Rau North American hydraulic system integrators, peb tuav kev ruaj ntseg Tshuag ntawm ib lub tog raj kheej vaj tse blanks, txo cov sij hawm txhuas los ntawm 12 lub lis piam mus rau 3 lub lis piam yam tsis muaj kev cuam tshuam cov ntaub ntawv pov thawj.
Xaiv lub tuam txhab kev pabcuam steel hlau tsis yog hais txog kev nrhiav qhov qis tshaj plaws - nws yog hais txog kev tshem tawm qhov hloov pauv uas ua rau kev ua haujlwm tsis tiav. Nws paub tias koj lub cobalt alloy plug yuav tsis tawg nyob rau hauv thermal shock vim nws dendrite caj npab sib nrug tau ntsuas thiab tswj. Nws tau txais lub hauv paus twj tso kua mis nrog nto tiav Ra ≤0.8 µm - tsis yog vim nws zoo nkaus li zoo, tab sis vim hais tias smoother nto ncua cavitation yaig los ntawm 3.2x nyob rau hauv abrasive kua. Qhov ntawd yog tus qauv QINGDAO QIANGSENYUAN TECHNOLOGY ntsib - tsis yog qee zaus, tab sis ua haujlwm. Thaum qhov tseeb qhov tseeb thiab cov qauv kev ncaj ncees tsis tuaj yeem sib tham, pib nrog metallurgy koj tuaj yeem taug qab, cov txheej txheem koj tuaj yeem siv tau, thiab cov txiaj ntsig koj tuaj yeem ua pov thawj.
