Xav tau precision hlau qhov-ceev? Tsis yog "ceev rau casting." Ceev nrooj peev casting Hoobkas txhais tau hais tias tig complex, siab-kev ncaj ncees Cheebtsam zoo li AMS 5387 cobalt alloy twj tso kua mis vaj tse los ntawm kos rau cov khoom xa tuaj nyob rau hauv 21 hnub. Qhov ntawd tsis yog acceleration. Nws yog reengineering lub sij hawm.
Peb tau xa ntau tshaj 1,200 qhov ceev-tig batch txij li xyoo 2020-feem ntau lub siab li qub, piston twj tso kua mis lub tog raj kheej vaj tse, thiab winch center ncej chais rau hydraulic OEMs thoob plaws North America thiab Europe. Dab tsi ua rau nws ua haujlwm tsis yog ceev ib leeg. Nws yog li cas nruj nreem casting, machining, thiab metallurgical tswj xauv ua ke.
Feem ntau foundries kho peev casting raws li ib tug standalone txheej txheem. Lawv muab cov qauv siv quav ciab, hluav taws kub nyhiab, cam khwb cia, ces xa mus rau lub khw muag khoom-yog tias muaj. Kev ncua sij hawm: kev kho cua sov teem sijhawm, kev sib koom ua ke ntsuas tshuab (CMM) backlog, cov khoom siv traceability gps. Peb pom ib tus neeg siv khoom tos 47 hnub tsuas yog kom paub meej tias phab ntsa tuab ntawm cov roj & roj ntsaws. Lawv qhov tshwj xeeb xav tau ± 0.05 hli kam rau ntawm 120 hli txoj kab uas hla cobalt-nickel. Kev ncua tsis yog los ntawm qeeb-nws yog los ntawm kev tawg.
Peb qhov kev daws teeb meem pib nrog kev sib koom ua ke ntsug - tsis yog lo lus buzz, tab sis raws li kev ua haujlwm txhua hnub. Kev tsim qauv siv quav ciab tshwm sim nrog GD&T tshuaj xyuas. Plhaub pwm burnout sij hawm dlhos nrog rau qhov cub muaj * thiab * CNC spindle load forecasts. Kev kho cua sov yog ua ntej validated rau txhua qib alloy - AMS 5387, T800, F22 steel - yog li tsis muaj batch tos rau thermal profileing. Txhua qhov tuaj ntawm cobalt alloy ingot nqa tag nrho cov ntawv soj ntsuam zeb; txhua qhov ua tiav khaws cia ntau-qib traceability mus rau tus nqi hluav taws xob.
Qhov no tshem tawm peb cov ntsiab lus tsis ua haujlwm hauv cov phiaj xwm nrawm nrawm:
- Dimensional drift ntawm casting thiab tiav machining- daws los ntawm tuav raws li-cam khwb cia siab rau ± 0.3 hli ntawm lub ntsej muag tseem ceeb, tom qab ntawd siv cov txheej txheem CMM pov thawj ua ntej kev sib tsoo zaum kawg
- Microstructure inconsistency nyob rau hauv high-alloy castings-hais los ntawm kev tswj cov cua txias hauv peb cov kab ISO 9001-cov ntaub ntawv pov thawj rau cov kab hluav taws xob thiab cov thermocouple real-time loggging rau ASTM E2862
- Surface defects surprises ntawm kev soj ntsuam zaum kawg- tiv thaiv los ntawm optical scanning ntawm tag nrho cov plhaub pwm ua ntej ncuav thiab automated porosity daim ntawv qhia ntawm 100% X-rayed qhov chaw
Qee tus tuaj yeem sib cav tias kev sib koom ua ke nruj ua rau kev hloov pauv yooj yim. Tab sis nyob rau hauv kev xyaum, qhov opposite tuav muaj tseeb. Thaum lub tuam txhab European lub twj tso kua mis xav tau rau 6 qhov kev hloov kho ntawm qhov tsis yog-tus qauv cobalt alloy nozzle-txhua qhov xav tau geometry tweaks thiab hloov kho txoj hauv kev validation-peb tau khiav tag nrho cov qauv hauv 11 hnub ib zaug. Vim li cas? Vim tias peb cov engineers validated casting feasibility * thaum lub sij hawm * CAD tshuaj xyuas - tsis tom qab tooling raug txiav. Tsis muaj redraws. Tsis muaj seem. Tsuas yog refinement nyob rau hauv tib lub system.
Cov txheej txheem no suav nrog plaub lub peev xwm ua haujlwm hauv ib lub ru tsev: peev casting (rau kev sib tw geometries txog li 45 kg), xuab zeb casting (rau cov qauv loj dua), ntau axis CNC machining (5-axis ib txhij rau impeller contours), thiab kev ua haujlwm nto-xws li HVOF txheej rau hnav zones thiab passivation. Tag nrho cov calibrated rau ASME B16.34, ISO 8502-3, thiab cov neeg siv khoom tshwj xeeb xau-test raws tu qauv.
Cov neeg siv khoom nug tiag tiag - thiab qhov peb teb ua ntej - tsis yog "Yuav nrawm npaum li cas?" Nws yog "Koj puas tuaj yeem tuav 0.002" ntawm qhov bore no thaum tswj cov nplej ntws ncaj ncees los ntawm cov fillet?" Los yog "Qhov T800 alloy plug no puas muaj sia nyob 15,000 psi cyclic loading yam tsis muaj microcrack pib?" Lossis "Koj puas muaj ntaub ntawv pov thawj tias koj AMS 5387 batch ua tau raws li AMS 2301 tensile thiab cov kev xav tau cuam tshuam?" Peb ua. Txhua lub sijhawm.
Kev xa khoom tiag tiag hauv ntiaj teb lees paub nws: 94.7% ntawm qhov nruab nrab-ntim xaj (50-500 pcs) nkoj hauv ± 2 hnub ntawm hnub cog lus. Tus qauv coj lub sij hawm nruab nrab 14 hnub los ntawm kev pom zoo kos duab mus rau thawj tsab ntawv xa-nrog rau daim ntawv qhia tag nrho, cov ntaub ntawv pov thawj, thiab NDT cov ntaub ntawv suav nrog. Tsis muaj add-ons. Tsis muaj kev zam.
Saib tom ntej, lub fwj tsis muaj peev xwm - nws yog qhov tsim nyog. Ntau cov haujlwm xav tau EN 10204 3.2 daim ntawv pov thawj, PED 2014/68 / EU ua raws, lossis API Q1 kev sib raug zoo. Yog li peb tab tom nthuav peb cov neeg thib peb cov kev soj ntsuam xyuas thiab tsim cov txheej txheem hybrid validation rau cam khwb cia-machined hybrids-xws li integrated valve lub cev qhov twg lub rooj zaum nplhaib yog peev-cam khwb cia * nyob rau hauv qhov chaw *, ces lapped kom phim lub qia bore.
Yog tias koj qhov project tom ntej no xav tau cov khoom hlau precision-tsis yog castings xwb, tsis yog machined qhov chaw, tab sis cov khoom sib xyaw ua ke ua kom ua tau raws li qhov siab-ces koj xav tau ntau tshaj li qhov chaw tsim khoom lossis lub khw muag khoom. Koj xav tau ib ceev peev casting Hoobkas qhov twg metallurgy, geometry, thiab lub sij hawm converge. Tsis yog raws li kev cog lus. Raws li kev coj ua.
