Thaum engineers qhia a poob ciab hlau casting Hoobkas rau lub hom phiaj tseem ceeb hydraulic li qub lossis cov twj tso kua mis siab, lawv tsis yog yuav khoom xwb-lawv tau txais kev ntseeg siab metallurgical. Peb tau pom ntau qhov haujlwm nyob rau ntawm qhov qauv qauv vim tias qhov chaw tsim khoom tsis tuaj yeem tuav ± 0.02 hli ntawm AMS 5387 cobalt alloy nozzle bore - lossis phem dua, xa cov qauv nplej tsis sib haum hla cov khoom siv. Tias yog vim li cas precision tsis yog kev lag luam thov ntawm no. Nws yog lub hauv paus.
Yog vim li cas poob ciab casting tseem yeej rau complex, high-alloy industrial Cheebtsam
Poob ciab hlau casting-tseem hu ua peev casting-tseem unmatched rau net-shaped complexity nyob rau hauv superalloys. Xuab zeb casting tsis tuaj yeem rov ua dua cov phab ntsa nyias nyias ntawm T800 cobalt-based piston twj tso kua mis lub tog raj kheej. Tuag casting tsis nrog cobalt-nickel lub siab melting point thiab abrasive xwm. Centrifugal casting tsis muaj GD&T tswj xav tau rau lub siab valve ports. Hauv kev xa tawm hauv ntiaj teb tiag tiag, peb niaj hnub pom qhov dav dav ntawm qhov siab tshaj ± 0.15 hli hauv cov xuab zeb-cam khwb cia sib npaug - txaus los ua rau lub foob tawg ntawm 3,000 psi. Kev nqis peev casting kho qhov ntawd. Nws cov txheej txheem ceramic plhaub xa cov nto tiav mus rau Ra 1.6 μm thiab kam rau ua kom nruj li ± 0.05 hli ntawm qhov tseem ceeb ntawm txoj kab uas hla - tsis muaj kev ua haujlwm thib ob ntawm 60% ntawm peb cov cobalt alloy twj tso kua mis.
Plaub lub peev xwm tsis tuaj yeem sib tham tau koj qhov poob ciab hlau casting Hoobkas yuav tsum ua pov thawj
Tus khub ntseeg tsis yog tsuas yog khiav cov qauv siv quav ciab thiab nchuav hlau. Lawv muaj physics qab nws. Nov yog qhov peb txheeb xyuas ua ntej pom zoo ib txoj haujlwm tshiab casting:
- Cov ntaub ntawv traceability mus rau tus xov tooj cua sov- tsis yog "AMS 5387 ua raws." Txhua qhov txuas cobalt alloy peb nrum nqa tag nrho cov ntawv xeem ntsuas, kuaj xyuas spectrographic, thiab cov ntaub ntawv keeb kwm thermal
- Nyob rau hauv-txoj kev CMM validation ntawm peb theem: Kev sib dhos siv quav ciab (ua ntej dewaxing), plhaub kev ncaj ncees (tom qab tua hluav taws), thiab tom qab cua sov-kho geometry (ua ntej ua tiav)
- Microstructure tswj los ntawm lub cub tawg daim ntawv qhia: tsis muaj chaw kub, tsis muaj chaw txias. Peb lub tshuab nqus tsev vacuum induction furnaces cav kub gradients txhua 12 vib nas this thaum lub sij hawm ncuav-tseem ceeb kom tsis txhob sigma theem nyob rau hauv cobalt-nickel alloys
- Functional tests ci rau hauv kev tso tawm: txhua lub siab valve casting undergoes helium leak kuaj ntawm 1.5 × ua hauj lwm siab ua ntej shipping
Qee tus yuav sib cav tias CNC machining ib leeg txaus rau qhov siab-precision. Txawm li cas los xij, machining AMS 5387 los ntawm cov khoom khib nyiab pov tseg 78% ntawm cov khoom siv - thiab qhia txog kev ntxhov siab uas cuam tshuam rau lub neej qaug zog hauv winch center ncej chais. Kev nqis peev casting pib ze-net zoo li. Tom qab ntawd peb tshuab tsuas yog qhov tseem ceeb: sealing nto, bearing journals, thiab xov cov ntaub ntawv. Qhov tshwm sim? 42% qis lub sij hawm voj voog thiab 3 × ntev kev pab cuam lub neej nyob rau hauv kev sim teb.
Qhov twg tsim lub hom phiaj ua tau raws li qhov kev muaj tiag
Peb tau txais cov lus nug no txhua lub limtiam: "Koj puas tuaj yeem pov lub geometry no?" Cov lus teb nyob ntawm tsawg dua ntawm CAD cov ntaub ntawv thiab ntau ntxiv txog seb qhov ua haujlwm li cas nyob rau hauv thermal stress. Nyias ribs hauv qab 4 mm vau nyob rau hauv lub plhaub. Ntse sab hauv cov ces kaum ntxiab ceramic residue. Draft angles nyob rau hauv 0.5 ° ua rau ciab ejection tsis ua hauj lwm. Yog vim li cas peb qhov kev tshuaj xyuas engineering yeej tsis nres ntawm GD&T. Peb simulate wax shrinkage, plhaub expansion, thiab hlau solidification siv MAGMASOFT® - thiab xa rov qab annotated drawings nrog manufacturability sau ntawv nyob rau hauv 48 teev. Piv txwv li, tsis ntev los no peb tau hloov kho lub hauv paus tsis yog tus qauv twj tso kua mis los ntawm kev ntxiv ob lub tswv yim gating risers. Uas tshem tawm microporosity nyob rau hauv lub load-bearing flange - thiab dhau ASTM E192 ultrasonic soj ntsuam rau thawj ncuav.
Xaiv koj qhov poob ciab hlau casting Hoobkas txhais tau hais tias xaiv koj cov saw hlau pheej hmoo profile
Cov neeg yuav khoom thoob ntiaj teb xaiv QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tsis yog rau tus nqi qis tshaj-tab sis rau tus nqi qis tshaj * tag nrho cov tswv cuab *. Lawv qhov chaw ISO-raws li kev sib koom ua ke casting, multi-axis machining, thiab passivation nyob rau hauv ib puag ncig tswj. Tsis muaj handoffs. Tsis muaj batch mismatches. Tsis surprise rework.
