Thaum cov engineers qhia cov khoom txhuas rau hydraulic manifolds, lub twj tso kua mis, lossis lub tshuab winch, lawv tsis tshua muaj pib nrog "xuab zeb casting." Lawv pib nrog ib qho teeb meem: siab thermal cycling, nruj GD&T tolerances, siab ncaj ncees ntawm 350+ bar - thiab xoom npoo rau micro-porosity los yog dimensional drift. Qhov ntawd yog qhov a xuab zeb casting aluminium Hoobkas nres ua tus neeg muag khoom thiab dhau los ua tus tsim txuas ntxiv. Ntawm QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., peb tau pom peb qhov kev rov ua tsis tiav hauv txhuas xuab zeb casting tej yaam num-tsis yog los ntawm kev xyaum tsis zoo, tab sis los ntawm qhov kev cia siab tsis zoo ntawm kev ua haujlwm engineering.
Ua ntej: piv txwv li "aluminium" txhais tau tias A380. Tsis yog. Nyob rau hauv peb lub khw, 75% ntawm txhuas xuab zeb castings khiav ntawm A383 los yog kev cai-hloov 319 variants-tshwj xeeb rau kev txhim kho fluidity nyob rau hauv nyias-phab ntsa twj tso kua mis foundation thiab zoo machinability tom qab T6 kho cua sov. Thib ob: overlooking pwm sand grain faib. Peb siv cov resin-bonded silica nrog kev tswj 45-75 µm gradation - tsis yog vim nws yog tus qauv, tab sis vim nws txiav nto roughness (Ra) los ntawm 30% piv rau cov xuab zeb ntsuab, txo cov sij hawm sib tsoo tom qab lub tog raj kheej flanges. Thib peb: hla pre-cam khwb cia FEA simulation ntawm solidification shrinkage. Ib tus neeg siv khoom hauv North American tau xa peb lub piston twj tso kua mis vaj tsev teeb duab nrog 22 hli tuab tav nyob ib sab ntawm 6 hli phab ntsa. Simulation flagged qhov chaw kub uas muaj kev pheej hmoo siab. Peb tau npaj ib qho chaw txias txias-thiab tshem tawm 100% ntawm cov kab noj hniav hauv cov kab noj hniav uas ua tsis tiav lawv thawj X-ray batch.
Dab tsi cais tus muaj peev xwm xuab zeb casting aluminium Hoobkas los ntawm ib qho uas xa cov haujlwm tseem ceeb? Vertical kev koom ua ke - tsis yog casting xwb, tab sis tag nrho cov saw hlau los ntawm kev xaiv alloy mus rau kev ua haujlwm validation. Peb tsuas yog muab ntawv pov thawj aluminium ingots nrog tag nrho cov ntawv xeem zeb (ASTM B179, EN 1706), tom qab ntawd ua OES tsom xam ntawm txhua lub pob zeb. Tsis muaj kev zam. Peb CNC machining hlwb zaum meters los ntawm qhov chaw nres tsheb shakeout - yog li castings txav ncaj qha mus rau hauv fixturing yam tsis muaj qhov kub thiab txias los ntawm kev ntxhov siab. Qhov ntawd yog li cas peb tuav ± 0.05 hli ntawm qhov chaw nres nkoj lub cev, txawm nyob ntawm 420 hli ntev vaj tse. Peb tsis "sim" los ua kev zam txim. Peb tswj txoj kev thermal los ntawm ncuav kom tiav txiav.
- Cobalt-alloy compatibility: Yog-peb niaj hnub nrum txhuas nyob ib ncig ntawm cobalt-nickel inserts (AMS 5387, T800) rau hybrid twj sib dhos. Qhov tseem ceeb yog kev sib txuas ua ke thiab kev tswj qhov kub ntawm qhov nruab nrab ntawm ± 15 ° C ntawm eutectic point.
- Kev ua haujlwm ntawm GD&T: Peb txheeb xyuas txoj haujlwm, profile, thiab kev khiav tawm siv Zeiss CONTURA CMMs - tsis yog ntawm kev tshuaj xyuas zaum kawg, tab sis tom qab kev siv tshuab ntxhib thiab dua tom qab kev ntxhov siab-nyem annealing.
- Traceability: Txhua qhov casting nqa ib lub laser-etched QR code txuas rau nws cov cav yaj, x-ray daim ntawv qhia, hardness nyeem ntawv, thiab daim ntawv pov thawj seem-tsis muaj ntawv txoj kev, tsis muaj ntaub ntawv ploj.
Qee qhov sib cav xuab zeb casting tsis tuaj yeem phim peev casting rau txoj kev aluminium geometry. Tab sis complexity tsis yog hais txog ib feem suav - nws yog hais txog kev ua haujlwm ceev ceev. Lub winch center ncej cov menyuam xav tau kev sib npaug ntawm cov khoom sib npaug, cov kabmob-qib saum npoo tiav ntawm OD, thiab cov txheej txheem tseem ceeb sib dhos thoob plaws 1.2-meter ntev. Xuab zeb casting ua haujlwm zoo dua li kev nqis peev thaum phab ntsa thickness txawv ntawm 8 hli mus rau 45 hli. Vim li cas? Vim tias peb tswj cov cua txias ntawm qhov chaw txias txias thiab lub tes tsho insulating - tsis yog cov khoom siv pwm xwb. Peb tau xa 210 kg txhuas castings nrog Cpk> 1.67 ntawm qhov tseem ceeb bores, txheeb xyuas nyob rau hauv load ntawm 400 bar hydraulic xeem rigs.
Kev xa khoom tiag tiag hauv ntiaj teb hinges ntawm ob yam uas cov neeg yuav khoom feem ntau saib: kev npaj cov khoom siv thiab cov txheej txheem pob tshab. Peb Tshuag A383 thiab 319 alloys nyob rau hauv 500 kg batch-pre-analyzed, pre-qhuav, npaj kom yaj nyob rau hauv 24 teev ntawm kev txiav txim kev pom zoo. Thiab peb muab cov kev hloov tshiab ntawm lub sijhawm tiag tiag: tsis yog "casting pib," tab sis "pwm sib dhos ua tiav ntawm 09: 22, ncuav teem sijhawm rau 14: 00, xav tias yuav tawm ntawm 18: 40." Qhov kev pom ntawd tso cai rau pawg neeg yuav khoom sib koom ua ke kev thauj mus los, QA pab pawg teem sijhawm CMM qhov qhib, thiab cov kws tsim qauv tsim qauv siv qhov ntev ntawm thawj kab lus ua ntej kev ua haujlwm theem nrab pib.
Yog tias koj qhov project aluminium casting tom ntej no xav tau ntau tshaj li daim ntawv tsocai-yog tias nws xav tau kev pom kev metallurgical, casting-machining interface npaj, thiab cov ntaub ntawv ua raws li cov roj & roj lossis mobile hydraulics-koj xav tau ib tus khub uas kho cov xuab zeb casting raws li cov txheej txheem engineering, tsis yog cov khoom lag luam. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ua haujlwm li ntawd - tsis yog vim nws lub suab zoo hauv lub vev xaib, tab sis vim tias lub siab li qub tso tawm, lub twj tso kua mis lub tog raj kheej tawg, thiab winch shafts ua tsis tiav thaum kev xav hloov cov ntaub ntawv. Peb tsim cov khoom txhuas uas muaj sia nyob thawj 10,000 lub voj voog - thiab tom ntej 100,000.
