Thaum engineers qhia tsis tshua muaj siab xuab zeb casting rau precision hlau qhov chaw, lawv tsis yog xaiv cov txheej txheem xwb-lawv tab tom xaiv cov thauj tog rau nkoj kev ntseeg tau. Peb tau pom nws ua ntej: lub tsev hydraulic twj tso kua mis tawg nyob rau hauv kev sim teb vim hais tias lub foundry hla solidification qauv. Lwm tus neeg siv tau ncua sij hawm tso tawm los ntawm 11 lub lis piam tom qab tau txais lub tog raj kheej vaj tse nrog cov graphite nodule tsis sib haum - tsis tuaj yeem tshawb pom yam tsis muaj metallography, tab sis tuag taus nyob rau hauv 350-bar cyclic loading. Tias yog vim li cas "tsawg siab xuab zeb casting Hoobkas" tsis yog ib lo lus tshawb fawb dav dav. Nws yog lub lim dej-ib qho uas cais cov neeg muag khoom uas nkag siab txog kev tswj xyuas cov khoom siv hlau los ntawm cov uas tsuas yog nchuav hlau.
Vim li cas Low Pressure Sand Casting Delives Precision where Gravity Fails
Lub ntiajteb txawj nqus casting ua haujlwm rau cov duab yooj yim. Tab sis thaum koj qhov chaw muaj cov phab ntsa nyias nyob ib sab ntawm cov dab dej kub loj - zoo li lub piston twj tso kua mis lub tog raj kheej vaj tse nrog 4.2 hli phab ntsa tuab tapering rau hauv 68 hli flange - lub ntiajteb txawj nqus ua rau muaj kev kub ntxhov, txias kaw, thiab txo qhov porosity ntawm cov kev ntxhov siab tseem ceeb. Tsis tshua muaj siab xuab zeb casting daws qhov no los ntawm kev thov 0.05-0.15 bar ntawm kev tswj cov roj inert siab rau lub molten hlau reservoir. Qhov no ua rau cov hlau nce siab los ntawm lub raj xa dej ceramic ntawm kev tswj kev tshaj tawm (feem ntau 12-18 mm / s), sau cov pwm kab noj hniav laminarly. Qhov tshwm sim? Directional solidification ntawm hauv qab mus rau sab saum toj, ze-zero entrapped gas, thiab seem stability nyob rau hauv ± 0.25 hli ntawm nta txog li 1,200 hli ntev.
Peb validate qhov no txhua hnub. Ntawm AMS 5387 cobalt alloy nozzles, tsis tshua muaj siab casting ua tiav 99.7% suab nrov hauv kev kuaj ultrasonic - piv rau 89% nrog lub ntiajteb txawj nqus. Qhov tseem ceeb tshaj, nws muab cov eutectic carbide dispersion zoo ib yam. Qhov ntawd tseem ceeb vim tias tsis sib xws carbide tes hauj lwm ua rau hnav ntxov ntxov nyob rau hauv cov kua dej siab. Peb cov neeg siv khoom hauv cov roj & roj daim ntawv tshaj tawm 3.2 × ntev kev pab cuam lub neej ntawm T800-raws li plugs cam khwb cia li no piv rau peev-cam khwb cia lwm txoj kev - tsis muaj txheej yuav tsum tau.
Plaub Tsis Muaj Peev Xwm Sib Tham hauv Lub Chaw Ua Haujlwm Tsis Txaus Siab Zoo Sand Casting Factory
Ib qho chaw muaj ntawv pov thawj ISO 9001 yog cov rooj tog zaum. Dab tsi cais cov neeg koom tes npaj ua tau zoo yog li cas lawv sib koom ua ke nrog cov kev xav tau hauv qab:
- Cov ntaub ntawv traceability mus rau tus xov tooj cua sov: Txhua pawg ntawm cobalt-nickel alloy nqa tag nrho MTRs nrog tensile, hardness, thiab intergranular corrosion test data-tsis yog chemistry.
- Nyob rau hauv-txoj kev solidification xyuas: Thermal imaging cameras taug qab kev nce qib hauv lub sijhawm; deviations ua rau tsis siv neeg hloov siab los yog rho tawm.
- CMM-kev sib koom ua ke qauv pov thawj: Ua ntej thawj zaug ncuav, peb luam theej duab tus qauv tawm tsam CAD siv Zeiss CONTURA G2, ntes cov ntawv tsis raug uas yuav ua rau kev puas tsuaj ejection.
- Hybrid finishing muaj peev xwm: Castings tawm ntawm qhov chaw nres tsheb shakeout thiab txav ncaj qha mus rau 5-axis CNC machining-tsis muaj kev tuav sab nraud. Qhov no khaws cia datum kev ncaj ncees rau GD & T-qhov tseem ceeb nta xws li coaxiality ntawm bore thiab mounting ntsej muag (± 0.015 hli).
Qee tus neeg tuaj yeem sib cav tias xuab zeb casting tsis tuaj yeem sib tw peev casting qhov chaw tiav. Muaj tseeb - rau daim iav tiav. Tab sis rau qhov chaw ua haujlwm? Peb as-cam khwb cia Ra nyob ntawm 12.5 µm ntawm thawj lub ntsej muag cov kabmob, poob rau 1.6 µm tom qab ua haujlwm. Qhov zoo tshaj plaws: ib yam nkaus thiab ua rau cov roj nplua nyeem tshaib plab hauv cov ntawv thov siab zoo li winch center ncej chais.
Qhov twg Precision ntsib Application Reality
Tsawg siab xuab zeb casting ci qhov twg physics thiab kev ua haujlwm sib tsoo. Xav txog engineering tsheb onboard winch systems: nruab nrab ncej chais tiv thaiv ua ke torsional shear, radial cuam tshuam, thiab abrasive paug. Lub ntiajteb txawj nqus-cam khwb cia cov menyuam ua tsis tiav ntawm 14,000 cycles. Peb cov ntawv tsis tshua muaj siab-siv hloov cov xuab zeb ntsuab nrog bentonite thiab carbon additives-siv tau 62,000 lub voj voog hauv kev sim nrawm. Vim li cas? Kev tswj cov cua txias tau khaws cia 22% ntau dua carbides hauv subsurface txheej, txheeb xyuas los ntawm SEM / EDS mapping.
Los yog nqa lub siab li qub rau cov tshuab hydraulic. Cov neeg siv khoom xav tau kev ua haujlwm tsis muaj paug ntawm 420 bar. Peb cov txheej txheem tuav lub rooj vag lub rooj zaum rau 0.008 hli hla 85 hli txoj kab uas hla-ua tau tsuas yog vim tias tsis tshua muaj siab tshem tawm pwm yaig los ntawm turbulent sau. Peb ntsuas txhua lub rooj zaum nrog Taylor Hobson PGI Optics, tsis yog cov qauv ntau.
Kev xaiv cov khoom sib txuas ua kom zoo dua. Thaum casting T800 cobalt-raws li alloys, cov pa xuab zeb pwm tawg nyob rau hauv thermal shock. Peb siv zircon-bonded refractory linings preheated rau 220 ° C - validated ntawm thermocouple arrays embedded nyob rau hauv pwm phab ntsa. Qhov ntawd tiv thaiv microfissures uas dhau los ua cov ntsiab lus pib rau kev qaug zog tawg.
