Thaum cov kws tshaj lij hais txog hlau xuab zeb casting rau lub siab-siab hydraulic li qub lossis hnav-tiv taus winch shafts, lawv tsis yog xaiv cov txheej txheem - lawv xaiv tus khub muaj peev xwm tuav ± 0.05 hli kam rau ua rau 400 HB castings thaum lav microstructural kev ncaj ncees thoob plaws txhua pawg. Qhov ntawd yog lub hauv paus kev ua haujlwm-tsis yog qhov zam-rau qhov tseeb hlau xuab zeb casting Hoobkas ua haujlwm rau lub hom phiaj tseem ceeb hauv kev lag luam.
Vim li cas Sand Casting Tseem Dominates Cov Khoom Siv Hlau Hlau
Ib txhia xav tias peev casting hloov xuab zeb casting rau precision qhov chaw. Tab sis nyob rau hauv lub ntiaj teb no tiag hydraulic twj tso kua mis vaj tse thiab piston lub tog raj kheej blocks, xuab zeb casting tseem irreplaceable - tshwj xeeb tshaj yog thaum phab ntsa thickness tshaj 50 hli, ib feem qhov hnyav saum toj 120 kg, thiab thermal stress kuj tseem ceeb tshaj qhov nto tag ib leeg. Peb tau pom peb qhov ua tsis tau tiav AMS 5387 cobalt alloy valve lub cev rov qab los ntawm tus neeg sib tw txoj kab uas ploj lawm vim tias qhov porosity txo qis tsim nyob ze rau hauv cov cua txias. Xuab zeb casting-nrog kev tswj ntsuab-xuab zeb permeability, kev tsim cov rooj vag meej, thiab kev saib xyuas lub sijhawm ntawm metallostatic siab - zam qhov kev pheej hmoo. Nws muab txoj hauv kev zoo tshaj plaws rau cov qib hlau zoo li QT600-3 thiab QT700-2, qhov twg lub zog tensile thiab elongation yuav tsum tau ua ke nyob rau hauv lub voj voog loading.
Plaub Tsis Muaj Peev Xwm Sib Tham ntawm Lub Tuam Txhab Txhim Kho Hlau Hlau Casting
Ib qho chaw muaj ntawv pov thawj tsis txaus. Dab tsi cais cov peev txheej tsim tau los ntawm kev ua raws li daim ntawv? Cov plaub yam no tshwm sim tsis tu ncua hauv kev sib koom tes ntev ntev:
- Cov ntaub ntawv traceability mus rau tus xov tooj cua sov- tsis yog tsuas yog daim ntawv pov thawj zeb, tab sis cov ntaub ntawv sau rau hauv cub tawg, spectrographic pov thawj ntawm lub ncuav, thiab khaws cia cov ntawv xeem ntawm ASTM A536
- In-process dimensional control ua ntej shakeout-siv embedded thermocouples thiab laser-scanned core sib dhos los kho cov nqi cua txias * ua ntej * zaum kawg solidification
- Machinability validation ntawm cam khwb cia nto-khiav cov cuab yeej-lub neej kev xeem ntawm cov qauv ua-cam khwb cia kom paub meej tias graphite morphology thiab zam tsis pub ntxov ntxov ua tsis tiav thaum CNC tiav
- GD & T-paub tus qauv tsim-Lub tsev datum lub hom phiaj rau hauv cov qauv ntoo yog li CMM tshuaj xyuas cov ntsiab lus ua ke nrog kev ua haujlwm mounting interfaces, tsis yog geometry arbitrary
Peb ib zaug tau pab European twj tso kua mis OEM txo qhov kev ua tsis tiav los ntawm 73% tsuas yog los ntawm kev hloov ntawm ib lub kaum sab xis ntawm lub hauv paus hlau hlau casting-hloov nws los ntawm kev txhawj xeeb kom zoo nkauj rau kev ua haujlwm thauj tog rau nkoj. Qhov kev pom zoo li no tsis yog los ntawm phau ntawv teev npe. Nws los ntawm kev khiav 18,000+ hlau castings ib xyoos ib zaug hla rau 6 hydraulic system platforms.
Qhov twg Hybrid Manufacturing ntxiv tus nqi tiag
Casting ib leeg tsis tshua daws qhov teeb meem tag nrho. Cov khoom muaj txiaj ntsig zoo tshaj plaws ua ke cov xuab zeb casting nrog precision machining - thiab tsis yog raws li cov kauj ruam ua ntu zus. Piv txwv li, engineering tsheb winch center ncej chais yuav tsum: (1) xuab zeb-cam khwb cia hlau blanks nrog optimized nodule suav rau qaug zog lub neej, (2) CNC tig uas tuav residual compressive kev nyuaj siab nyob rau hauv cov bearing journal, thiab (3) xaiv induction hardening * nkaus xwb * ntawm qhov chaw tiv tauj - tawm hauv cheeb tsam flange ductile retention. Qhov no hybrid mus kom ze txiav tag nrho cov nqi los ntawm 22% piv rau tag nrho machined steel forgings thaum txhim kho kev pab cuam lub neej los ntawm 40% nyob rau hauv abrasive lub luag hauj lwm voj voog. Nws tsuas yog ua haujlwm thaum tib pab pawg tswj hwm ob qho tib si casting metallurgy thiab machining tsis-tsis muaj kev sib tw, tsis muaj kev xav.
Xaiv Koj Lub Hoobkas Hlau Hlau Casting: Peb Cov Lus Nug Uas Qhia Txhua Yam
Tsis txhob nug "Koj lub sijhawm ua haujlwm yog dab tsi?" Nug es tsis txhob:
- "Qhia kuv tias koj qhov kev tsis lees paub peb qhov kawg-ua rau txhua qhov ua tsis tiav, thiab koj ua pov thawj li cas qhov kho tau ua haujlwm?" Yog tias lawv tsis kam los yog hais txog "cov neeg siv khoom tshwj xeeb hloov pauv," taug kev mus. Kev txheeb xyuas hauv paus-ua rau tsis muaj kev sib tham.
- "Koj ua li cas txheeb xyuas cov duab graphite thiab kev faib tawm * ua ntej * machining pib?" Cov lus teb tau txais suav nrog: kev txheeb xyuas cov duab zoo ib yam ISO 945-1, txheeb xyuas cov qauv siv; Cov lus teb tsis txaus ntseeg suav nrog "peb tus kws ua haujlwm hauv tsev tshawb xyuas nws."
- "Koj puas tuaj yeem tuav txoj haujlwm kam rau ntawm Ø0.1 hli ntawm 300 hli txoj kab uas hla drilled los ntawm cov xuab zeb nrum vaj tse?" Yog txhais tau hais tias lawv tau lees paub qhov tseem ceeb ntawm kev ua kom rov ua tau zoo dua qub, kev them nyiaj thermal loj hlob, thiab kev kho tom qab kev kho cua sov distortion qauv. Tsis tau txhais hais tias lawv tseem tsis tau ua qhov kev sim no.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ntsib tag nrho peb. Lawv qhov ISO-raws li qhov chaw hauv Qingdao khiav txhua hnub kev tshuaj xyuas metallographic, tswj xyuas tag nrho cov cua sov-rau-ib feem traceability, thiab validates txhua tsev neeg casting tiv thaiv kev ua tau zoo ntawm cov qauv ntsuas - tsis yog qhov seem dhau / tsis ua haujlwm. Lawv ua haujlwm rau North American hydraulic OEMs, EU lub twj tso kua mis sib koom ua ke, thiab cov tuam txhab tsim khoom siv hluav taws xob sab hnub tuaj Asia-tsis nrog cov lus qhia dav dav, tab sis nrog GD & T- tshuaj xyuas cov lus qhia ua ntej xaj xaj.
Ib hlau xuab zeb casting Hoobkas khwv tau kev ntseeg tsis yog los ntawm kev cog lus zoo tag nrho, tab sis los ntawm kev ua pov thawj tias nws ua li cas rau qhov tsis zoo. Thaum koj tom ntej no lub siab valve tsev yuav tsum muaj sia nyob 200,000 cycles ntawm 350 bar - los yog koj lub winch ncej yuav tsum tiv thaiv galling nyob rau hauv ntsev-laden marine ib puag ncig - tus khub txoj cai tsis yog tsuas yog nchuav hlau. Lawv txhim kho nws tus cwj pwm, ib qho kev tswj kom ruaj khov ntawm ib lub sijhawm.
