Thaum engineers qhia a casting hlau qhov, lawv tsis tsuas yog xaj ib qho duab-lawv tau cog lus rau qhov kev ruaj ntseg nyob rau hauv 300 bar, microstructure kev ncaj ncees tom qab thermal cycling, thiab nto tiav uas tiv thaiv galling hauv abrasive hydraulic txaus. Peb tau pom ntau qhov chaw nres tsheb ntawm cov qauv qauv vim tias qhov kev tiv thaiv kev ua haujlwm tau ua tsis zoo nrog cov nyiaj siv ua haujlwm zaum kawg - lossis phem dua, vim tias cov ntaub ntawv pov thawj tsis sib haum rau cov kev kho cua sov uas xav tau rau kev qaug zog.
Yog vim li cas "Tsuas Cast" tsis txaus rau Lub Hom Phiaj-Critical Applications
Casting hlau qhov chaw rau hydraulic li qub, piston twj tso kua mis vaj tse, los yog winch center shafts xav tau ntau tshaj qhov muaj peev xwm foundry. Nws yuav tsum to taub yuav ua li cas solidification shrinkage cuam tshuam nrog CNC Tshuag tshem tawm, yuav ua li cas cobalt-nickel alloys teb rau peev piv rau xuab zeb casting, thiab yog vim li cas AMS 5387 cobalt alloy 6 coj txawv nyob rau hauv nyias phab ntsa nozzles piv rau tuab-section plugs. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb kho txhua qhov casting raws li ib qho kev tshwm sim metallurgical - tsis yog hloov pauv geometry. Qhov ntawd txhais tau hais tias kev txheeb xyuas cov qauv ntawm macroetch ntawm txhua qhov cua sov, ua kom muaj qhov sib txawv ntawm interdendritic ua ntej machining pib, thiab daim ntawv qhia kev ntxhov siab nyob thoob plaws lub tog raj kheej flanges siv cov strain-gauge arrays.
Peb tau saib cov neeg siv khoom hloov pauv tom qab pom qhov tsis sib xws ntawm qhov nyuaj hauv T800 cobalt-based castings-tsuas yog nrhiav cov hauv paus hauv paus tsis yog lub hauv paus, tab sis tsis muaj kev tswj hwm preheat thaum lub sij hawm vuam ntawm machined nta. Peb cov txheej txheem kev koom ua ke tshem tawm qhov sib txawv: casting, kev kho cua sov, thiab ntau qhov axis tiav tshwm sim nyob rau hauv ib lub ru tsev, nrog rau tag nrho traceability los ntawm raw billet daim ntawv pov thawj mus rau qhov kawg CMM daim ntawv qhia. Tsis muaj handoffs. Tsis muaj batch splits. Tsuas yog ib qho kev tswj xyuas thermal thiab mechanical keeb kwm ib feem.
Plaub Pawg Casting—Txhua qhov tsim los rau kev ua haujlwm, tsis yog daim ntawv
Tsis yog txhua qhov castings ua haujlwm tib lub hom phiaj. Peb cov ntaub ntawv qhia txog kev ua tsis tiav tiag tiag hauv ntiaj teb - thiab yuav ua li cas tiv thaiv lawv:
- Hlau castings: Siv rau lub hauv paus twj tso kua mis qhov chaw vibration damping tseem ceeb tshaj tensile lub zog - yog li peb optimize graphite nodule suav thiab pearlite / ferrite piv, tsis yog Brinell hardness.
- Hlau thiab stainless hlau castings: Rau lub siab valve lub cev raug cov tshuaj chloride-nplua nuj oilfield kua-peb validate pitting resistance equivalent (PREN) tus nqi ib ASTM A959, tsis yog chemistry qhia
- Cobalt-nickel alloy Cheebtsam: suav nrog AMS 5387 cobalt alloy 6 lub twj tso kua mis, qhov twg carbide faib dictates hnav lub neej-peb ua SEM-EDS daim ntawv qhia ntawm hla ntu, tsis yog kho qhov muag microscopy.
- Tsis yog-tus qauv T800 alloy fabrications: Qhov twg geometry defies cov pa toolpaths - peb muab peev casting nrog 5-axis zeb-tig los tuav ± 0.015 hli GD&T ntawm coaxial bores thiab radial runout nyob rau hauv 0.02 hli
Qhov no tsis yog theoretical. Ib qho European OEM rov tsim kho lawv cov twj tawm sab nraud lub tog raj kheej lub tsev tom qab peb qhov ua tsis tiav. Lawv thawj tus neeg muag khoom tau tuav nruj-tab sis tsis xav tau qhov sib txawv nruab nrab ntawm dendrite caj npab sib nrug. Peb rov tsim kho lub rooj vag kaw lus, ntxiv cov kev taw qhia kev ruaj ntseg, thiab xa cov khoom pov thawj nrog SDAS ≤ 45 µm. Lub neej hauv teb chaws tau nce los ntawm 8 lub hlis mus rau ntau dua 26.
Qhov twg Feem ntau cov neeg muab khoom txiav txiav-Thiab peb kaw qhov sib txawv li cas
Qee cov tuam txhab lag luam kho qhov kev txiav txim hlau ua cov khoom lag luam. Lawv lees txais cov duab kos, tsocai rau lub sijhawm, thiab nkoj. Peb pib ua ntej-nrog koj pab neeg engineering.
Thaum lub sij hawm kos duab validation, peb chij muaj feem xyuam rau feem ntau saib: phab ntsa thickness hloov uas caw kub tearing nyob rau hauv cobalt alloys; cov kaum sab xis qis heev rau kev tshem tawm cov plhaub ceramic hauv peev castings; los yog GD&T callouts uas tsis sib haum nrog ua tiav raws li-cam khwb cia nto roughness (Ra> 6.3 µm rau xuab zeb, Ra> 3.2 µm rau peev). Peb tsis yog hais tias "nws nyuaj rau ua." Peb tawm tswv yim lwm txoj hauv kev-xws li hloov qhov chaw datum rau qhov chaw ua haujlwm, lossis qhia qhov chaw txias txias kom tswj tau qhov shrinkage hauv tus thawj coj tseem ceeb.
Peb kuj kuaj seb lwm tus xav li cas: cov ntaub ntawv pov thawj tuaj yeem raug txheeb xyuas qhov tseeb ntawm qhov ntsuas kub ntawm OES spectroscopy. Txhua qhov ntau dhau mus kuaj ultrasonic rau subsurface porosity ua ntej machining pib. Thiab kev soj ntsuam zaum kawg suav nrog kev sim ua haujlwm - lub siab lub cev valve rau 1.5 × kev ua haujlwm siab, tom qab ntawd kuaj xyuas qhov xau ntawm 0.05 cc / min pib.
Xaiv tus khub zoo txhais tau tias nug cov lus nug zoo
Ua ntej koj ua tiav koj cov khoom siv hlau tom ntej, nug:
- Koj puas tuaj yeem qhia kuv qhov kawg peb CMM cov lus ceeb toom rau cov duab geometry zoo sib xws - thiab qhia txog qhov koj tau kho qhov tsis txaus ntseeg ntawm ntau ntau?
- Dab tsi yog koj qhov kev khiav ntev tshaj plaws ntawm AMS 5387 castings yam tsis muaj kev tsis lees paub? Dab tsi yog lub hauv paus ua rau thawj qhov tsis ua haujlwm - thiab koj kho nws li cas?
- Koj puas tswj ob qho tib si casting thiab zaum kawg machining? Yog tsis yog, leej twg validates lub interface ntawm as-cam khwb cia thiab as-machined datums?
- Koj ua li cas txog kev taug qab rau cov khoom tseem ceeb? Puas yog ntau-theem-los yog cua sov-theem, nrog tag nrho cov ntaub ntawv thermal keeb kwm?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. teb yog rau tag nrho plaub. Peb tsis tsuas yog xa cov castings. Peb muab kev ntseeg siab-hauv qhov seem rov ua dua, cov khoom siv sib xws, thiab kev ntseeg tau ua haujlwm. Vim hais tias nyob rau hauv hydraulic systems, engineering tsheb, thiab cov khoom siv roj & roj, tsis muaj paj rau "ze txaus."
Yog koj tom ntej casting hlau qhov yuav tsum ua nyob rau hauv siab, hnav, thiab thermal stress - pib nrog metallurgy, tsis yog kev lag luam. Pib nrog cov txheej txheem pov thawj tswj, tsis yog cov ntawv cog lus. Pib qhov twg precision pib: hauv pwm, yaj, thiab ntsuas.
