Thaum engineers qhia machined hlau casting Hoobkas cov kev pabcuam, lawv tsis yog xaj cov khoom xwb-lawv tab tom ua kom ruaj khov nyob rau hauv 300-bar hydraulic loads, microstructure kev ncaj ncees tom qab kev kho cua sov, thiab qhov chaw tiav uas tiv taus abrasive slurry hauv oilfield twj tso kua mis. Qhov ntawd yog qhov pib feem ntau cov neeg muag khoom tsis nco. Peb tau pom ntau zaus: ib feem dhau ntawm CMM tshuaj xyuas ntawm cov khoom xa tuaj tab sis ua tsis tiav kev sim ua haujlwm tom qab 48 teev ntawm lub luag haujlwm - vim tias graphite nodule faib tsis tau lees paub ua ntej machining, lossis vim tias machining-induced residual stress cracked lub bore thaum lub sij hawm cycling.
Vim li cas Hlau Castings Xav Tau Ntau Tshaj Li Casting-lossis tsuas yog Machining
Hlau castings rau precision daim ntaub ntawv-xws li piston twj tso kua mis lub tog raj kheej vaj tse los yog winch center ncej chais-nyob ntawm kev sib tshuam ntawm metallurgy thiab geometry. Sand-cam khwb cia hlau hlau (ASTM A536 Qib 65-45-12) muab lub zog tensile thiab damping muaj peev xwm. Tab sis raws li-moulded nto tsis tshua muaj ± 0.025 hli txoj hauj lwm kam rau ua ntawm cov phau ntawv sau. Qhov ntawd yog qhov kev sib koom ua ke ntsug yuav tsis sib tham. Ntawm peb qhov chaw nyob hauv Qingdao, cov hlau nyoos nchuav rau hauv cov xuab zeb pwm ib qho ua haujlwm - thiab los ntawm qhov tom ntej, cov castings tau txais kev ntxhov siab, tig CNC tig, ua tiav milling ntawm 5-axis tshuab nrog Renishaw soj ntsuam. Tsis muaj handoffs. Tsis muaj batch misalignment. Tsis muaj kev kwv yees txog thermal expansion coefficient hla cov txheej txheem txheej txheem.
Peb tau ntsuas qhov cuam tshuam: cov khoom siv hauv 72 teev ntawm casting qhia 40% qis dua tom qab kev ua haujlwm tsis zoo dua li cov khoom khaws cia rau ob lub lis piam. Vim li cas? Vim tias peb tswj cov cua txias nkhaus los ntawm ncuav mus rau anneal-thiab peb tshuab ua ntej theem nrab nag lossis daus xauv hauv kev ntxhov siab. Qhov ntawd tsis yog txoj kev xav. Nws yog cov ntaub ntawv nkag mus hla 1,200+ ntau lawm khiav txij li xyoo 2019.
Tus nqi tiag tiag ntawm "Standard" Iron Casting Suppliers
Qee cov neeg yuav khoom kho cov hlau casting zoo li cov khoom siv hlau phaj - xaj qib, tau txais ntawv pov thawj, txav mus. Tab sis thaum koj lub siab valve lub cev yuav tsum kaw ntawm 250 ° C thaum tiv thaiv H₂S corrosion, ASTM A536 tsis txaus. Koj xav tau traceability mus rau ladle chemistry: carbon equivalent (CE) ntawm 4.2-4.5, sulfur <0.015%, thiab nodularity>85% lees paub los ntawm ASTM E2352 metallography - tsis yog tensile tuav.
Peb muab cov ntaub ntawv pov thawj hlau los ntawm peb lub ISO 9001 foundries nrog cov ntaub ntawv ladle-rau-casting traceability. Txhua qhov cua sov tuaj nrog cov ntaub ntawv spectrometric thiab cov duab microstructure. Yog tias tus neeg siv khoom nug rau "AMS 5387-tshaj hlau," peb tsis hloov pauv - peb piav qhia vim li cas cobalt-nickel alloys koom nrog hauv cov nozzles thiab ntsaws, thaum cov hlau tsis zoo nodularity yog nyob rau hauv cov khoom siv thauj khoom. Precision tsis yog hais txog kev ua siab ntev dua ib leeg. Nws yog hais txog kev coj tus cwj pwm ntawm cov khoom siv rau kev ua haujlwm physics.
Yuav ua li cas tshwm sim nyob rau hauv lub High-Performance Machined Hlau Casting Factory
Taug kev los ntawm peb lub khw hauv pem teb, thiab koj yuav pom peb qhov kev ua haujlwm synchronized khiav ua ke:
- Casting npaj: Pwm simulation (siv MAGMASOFT®) validates gating design ua ntej thawj ncuav-tsis muaj txias shuts nyob rau hauv nyias-phab ntsa twj tso kua mis foundation.
- Machining tswj: Txhua Okuma MULTUS U3000 executes G-code validated tiv thaiv STEP AP242 qauv; cov cuab yeej hnav cov nyiaj them hloov tshiab txhua 12 qhov chaw uas siv cov txheej txheem laser ntsuas.
- Kev soj ntsuam nruj: Txhua qhov tseem ceeb tau txais kev kuaj xyuas peb zaug - thawj zaug nrog CMM, thib ob nrog kev sib piv kho qhov muag, thib peb nrog kev ua haujlwm gage simulating tiag tiag kev cuam tshuam.
Tsis muaj kauj ruam yog hla. Tsis muaj "kev tshuaj ntsuam zaum kawg" yog lub foob roj hmab. Thaum tus neeg siv khoom xa GD & T-hnyav kos duab rau engineering tsheb winch shafts, peb cov engineers chij muaj peev xwm ua haujlwm sib tsoo * ua ntej * quoting - tsis yog tom qab txiav cov khoom seem.
Xaiv koj tus khub tsis yog hais txog Geography-Nws yog hais txog tus txheej txheem muaj tswv
North American OEMs feem ntau xav tias offshore casting txhais tau tias ncua NRE cov lus tawm tswv yim lossis kev kho cua sov tsis sib haum. Tab sis lub sij hawm zones muaj teeb meem tsawg dua li kev sib raug zoo. Peb khiav txhua hnub engineering syncs ua lus Askiv, lus Mev, thiab German - siv cov qauv MBD sib koom nrog lub sijhawm tiag tiag. Thaum lub tuam txhab European hydraulics xav tau ISO 13849-raws li lub cev valve, peb koom tes tsim lub voj voog kev ntxhov siab nrog lawv pab pawg - thiab xa cov ntaub ntawv PPAP Qib 3 hauv 11 hnub.
Qhov no ua tau vim peb machined hlau casting Hoobkas tsis outsource metallurgy, kev kho cua sov, lossis kev soj ntsuam zaum kawg. Peb muaj tag nrho pawg-los ntawm molten hlau chemistry rau nto roughness Ra ≤0.8 µm ntawm sealing ntsej muag. Thiab peb sau nws tag nrho: cov ntaub ntawv pov thawj, cov ntaub ntawv kho cua sov, CMM cov ntaub ntawv, thiab txawm tias cov ntaub ntawv txias pH rau cov kab machining tuav T800-alloy nyob ib sab.
Yog tias koj qhov project tom ntej no xav tau cov hlau castings uas muaj sia nyob 10,000 cycles ntawm 200 MPa kev ntxhov siab - lossis yog tias koj tseem tab tom sib cav seb puas yuav pov thawj lossis tshuab ua ntej - pib nrog cov khoom siv, tsis yog cov khoom muag. Precision pib qhov twg hlau solidifies. Txhua yam ua raws li.
