Thaum koj hnov 'poob ciab xuab zeb casting', feem ntau xav txog cov hniav nyiaj hniav kub zoo nkauj lossis kos duab. Qhov ntawd yog qhov cuab yeej cuab tam. Nyob rau hauv kev lag luam ntsiab lus, tshwj xeeb tshaj yog rau complex, tsawg-rau-nruab nrab ntim hlau Cheebtsam, nws yog ib tug txawv tsiaj nyaum nkaus. Nws tsis yog tsuas yog ua cov pwm; Nws yog hais txog kev tswj kev sib yuav ntawm tus qauv siv quav ciab thiab cov xuab zeb uas muaj zog, paub meej qhov twg cov txheej txheem yuav tawm tsam koj, thiab muaj cov machining thaub qab los ntxuav qhov mess nws inevitably tawm tom qab.
Lub hauv paus tsis meej pem: Nws tsis yog Pure Investment Casting
Cov neeg feem ntau lum nws tag nrho nyob rau hauv 'kev nqis peev casting'. Tab sis qhov tseeb peev casting siv lub plhaub ceramic. Poob ciab xuab zeb casting yog nws rougher, ntau pragmatic kwv tij txheeb ze. Koj tseem pib nrog cov quav ciab lossis cov qauv soluble - qhov ntawd yog qhov 'poob ciab'. Tab sis es tsis txhob tsim cov txheej txheem ceramic, koj ntim cov qauv ntawd rau hauv lub khob xuab zeb, feem ntau siv cov xuab zeb-pob zeb. Koj yaj cov wax tawm, ncuav hlau rau hauv. Qhov saum npoo tiav yuav tsis zoo li iav li lub plhaub ua haujlwm, tab sis rau ntau qhov chaw ua haujlwm, tshwj xeeb tshaj yog cov loj dua, nws yog qhov chaw qab zib zoo. Qhov kev sib tw yog tswj cov xuab zeb tus cwj pwm thaum burnout thiab ncuav.
Qhov twg koj yeej pom qhov txawv yog nyob rau hauv cov cua ntsawj ntshab. Rau lub plhaub ceramic, koj tuaj yeem tawm mus nrog zero lub kaum sab xis ntawm cov qauv. Nrog xuab zeb, koj xav tau ntau dua. Tsis ntau, tab sis txaus kom cia cov xuab zeb compact kom zoo thiab tso tawm yam tsis muaj tearing. Kuv tau pom tej yaam num ua tsis tiav vim tus tsim qauv, siv los nqis peev casting specs, xa tus qauv nrog ntsug phab ntsa rau cov txheej txheem xuab zeb. Cov cores tawg. Nws yog ib qho mess. Koj yuav tsum tsim cov pwm nruab nrab.
Qhov no yog qhov chaw ntawm lub khw kev paub yog txhua yam. Ib lub tuam txhab zoo li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), nrog rau lawv peb lub xyoo caum hauv casting thiab machining, zoo li yuav pom txhua iteration ntawm qhov no. Lawv sau ob lub plhaub pwm (lwm lub sij hawm rau ceramic plhaub peev casting) thiab peev casting cais ntawm lawv qhov chaw https://www.tsingtaocnc.com, uas qhia kuv tias lawv nkag siab qhov sib txawv. Thaum koj ua haujlwm nrog cov alloys tshwj xeeb - npib tsib xee-raws li, cobalt-raws li-qhov sib txawv tseem ceeb dua. Lub rooj vag kaw lus rau lub superalloy hauv cov xuab zeb pwm piv rau lub plhaub ceramic yog lub ntiaj teb sib nrug ntawm cov cua kub dissipation thiab muaj peev xwm rau kev suav nrog.
Xuab zeb nws tus kheej: Ntau tshaj li qhov av xwb
Lub 'xuab zeb' nyob rau hauv lub npe yog dag. Nws tsis yog chaw ua si xuab zeb. Nws feem ntau yog silica los yog zircon xuab zeb, coated nrog ib tug resin binder - feem ntau yog ib tug phenolic los yog furan system. Qhov sib piv, lub sijhawm sib tov, qhov kub thiab txias; cov no tsis yog txawv txav, lawv yog cov lus txib. Tau qhov sib tov tsis raug, thiab koj lub zog pwm tawm. Tsis muaj zog heev, nws tawg thaum lub sij hawm nchuav. Muaj zog heev, nws tsis tso cai rau cov hlau kom zoo, ua rau lub kua muag kub hauv qhov casting nws tus kheej.
Peb kawm qhov no txoj kev nyuaj ntawm ib pawg ntawm stainless hlau valve lub cev. Cov xuab zeb tau kho dua. Cov castings tau tawm los saib zoo meej, tab sis kev kuaj ultrasonic qhia lub vev xaib ntawm micro-cracks ze ntawm cov chaw thermal. Cov pwm yog nruj heev, sib ntaus sib tua cov hlau thaum nws txias. Yuav tsum khawb tag nrho. Kev kho tsis nyuaj - tsuas yog kho lub voj voog kho - tab sis paub tias yuav kho li cas los ntawm xyoo ntawm kev sib txuas tsis ua haujlwm rov qab mus rau cov txheej txheem tsis ua haujlwm.
Lwm nuance yog cov xuab zeb reclamation. Koj tsis tuaj yeem rov siv nws tsis kawg. Lub binder tawg, nplua nplua. Ib tug zoo foundry saib LOI (Poob ntawm Ignition) ntawm lawv reclaimed xuab zeb. Kuv yuav xav paub seb yuav ua li cas ua haujlwm ntev li QSY tswj lawv cov xuab zeb lifecycle, tshwj xeeb tshaj yog thaum hloov ntawm cov ntaub ntawv xws li cam khwb cia hlau thiab npib tsib xee alloys. Kev sib kis ntawm cov xuab zeb los ntawm ib tsev neeg hlau mus rau lwm tus tuaj yeem qhia cov kab ke uas ua rau cov hlau tawg.
Tus Qauv Wax: Qhov twg Dimensional Control pib (thiab xaus)
Txhua yam hinges ntawm tus qauv. Rau poob ciab xuab zeb casting, koj feem ntau siv cov softer, qis-melting-point siv quav ciab tshaj rau ceramic plhaub ua hauj lwm. Nws yuav tsum nruj txaus los tuav cov xuab zeb ramming tab sis mos txaus kom yaj tawm huv si yam tsis muaj residue. Cov seem yog tus tua neeg. Txhua qhov seem carbonaceous gunk los ntawm cov quav ciab yuav tsim cov roj tsis xws luag hauv qhov casting.
Kev txhaj tshuaj tsis haum rau cov quav ciab muaj teeb meem ntau dua li feem ntau xav. Siab, kub, thiab tuav lub sij hawm cuam tshuam rau cov quav ciab shrinkage thiab nto zoo. Ib me ntsis sunken nto ntawm cov quav ciab yuav zoo li tsis tseem ceeb, tab sis nws txhais ncaj qha mus rau ib qho chaw nyias ntawm phab ntsa hlau kawg. Peb ib zaug muaj qhov tsis xws luag ntawm lub twj tso kua mis - ib txwm nyob hauv tib seem. Siv peb lub lis piam los taug qab nws rov qab mus rau qhov siv quav ciab txhaj pwm txias tsis sib npaug. Cov qauv siv quav ciab tau hloov pauv thaum nws txias, tab sis nws yog qhov hloov maj mam koj tsuas pom nws nrog jig kos.
Qhov no yog vim li cas kev koom ua ke nrog machining, zoo li CNC cov kev pabcuam QSY muab, yog tsis sib tham. Koj tsis tshua tau txais cov duab puab los ntawm cov txheej txheem no, tshwj xeeb tshaj yog nrog cov geometry nyuaj. Cov qauv khoom siv hnav, cov xuab zeb hloov ib feeb. Qhov zoo li-cam khwb cia yog koj cov khoom ntxhib. CNC machining theem yog qhov uas koj ntaus qhov kawg qhov ntev thiab kam rau ua. Nws yog ob txoj kev ua si: casting tau txais koj 95% nyob ntawd, machining muab qhov kawg 5% nrog precision.
Gating and Feeding: Unseen Engineering
Qhov no yog cov xim dub ntawm kev ua haujlwm hauv tsev. Pouring molten hlau rau hauv cov xuab zeb pwm tsis zoo li sau lub thoob. Koj xav tau ib lub kaw lus - khiav, rooj vag, risers - los tswj qhov ntws thiab pub shrinkage raws li cov hlau solidifies. Rau poob ciab xuab zeb casting, qhov system no feem ntau ua rau hauv cov qauv siv quav ciab nws tus kheej. Ntau cov qauv siv quav ciab txuas nrog lub hauv paus ciab 'ntoo' uas ua rau lub khob ncuav thiab cov neeg khiav dej num.
Tsim tsob ntoo no yog kev paub dawb huv. Muab cov riser tso rau hauv qhov chaw tsis raug, thiab koj tsim lub thermal hotspot uas ua tau txhawb nqa qhov porosity. Siv lub rooj vag me me, koj tau txais huab cua khiav thiab txias kaw. Loj dhau, thiab koj tsim ntau dhau turbulence uas entraps xuab zeb thiab slag. Kuv nco qab txog ib qhov project rau marine-qib bronze haum qhov twg peb pheej nrhiav cov xuab zeb inclusions. Peb tweaked lub pouring kub, lim cov hlau, tsis muaj dab tsi ua hauj lwm. Thaum kawg, tus tsim qauv qub tau saib nws thiab hais tias lub rooj vag nkag mus rau hauv cov pwm kab noj hniav ntawm lub kaum ntse ntse, ua rau cov hlau yaig thiab ua rau cov xuab zeb tawg. Nws yog lawm. Ib qho yooj yim hloov nyob rau hauv lub wax assembly layout daws nws.
Qhov kev daws teeb meem no yog qhov koj xav tau los ntawm tus kws tshaj lij. Saib ntawm cov ntaub ntawv QSY ua haujlwm nrog-stainless, tshwj xeeb alloys-tus qauv tsim yog qhov tseem ceeb tshaj. Cov alloys no muaj qhov sib txawv fluidities thiab solidification qauv dua li cov pa roj carbon steel. Lub rooj vag tsim uas ua haujlwm rau cam khwb cia hlau yuav ua rau tawg nyob rau hauv ib tug nickel-raws li alloy. Nws tsis yog ib qho loj-haum-tag nrho cov txheej txheem.
Vim li cas Nws Tseem Tseem Ceeb Hauv Lub Ntiaj Teb CNC
Nrog niaj hnub 5-axis CNC tshuab, koj yuav nug yog vim li cas thab nrog casting txhua? Vim li cas ho tsis tsuas yog tshuab los ntawm cov khoom bar? Rau ib-tawm prototypes, tej zaum. Tab sis rau ntau lawm khiav ntawm 50-100 daim, poob ciab xuab zeb casting yeej ntawm cov khoom siv efficiency thiab tus nqi, tshwj xeeb tshaj yog nrog kim alloys. Koj tab tom muab hlau tsuas yog qhov uas nws xav tau, tsis ua kom deb li 70% ntawm tus nqi npib tsib xee alloy billet. Qhov ze-net-zoo nam txuag tsis tau tsuas yog cov khoom, tab sis loj npaum li cas ntawm machining lub sij hawm.
Nws kuj tso cai rau geometries uas yog impractical los yog tsis yooj yim sua nrog machining ib leeg. Sab hauv cov kab, undercuts, complex curved nto-cov no tuaj yeem tsim ncaj qha los ntawm pwm. Tom ntej no CNC ua hauj lwm yog ces rau precision ntsej muag, threads, thiab mating nto. Nws yog hybrid manufacturing philosophy. Ib lub tuam txhab muab ob qho tib si casting thiab machining nyob rau hauv ib lub ru tsev, raws li QSY ua, nkag siab qhov kev sib koom ua ke no. Lawv tuaj yeem txhim kho qhov tsim qauv rau tag nrho cov kev tsim khoom, tsis yog ib theem ntawm nws.
Qhov kev sim tiag tiag yog nyob rau hauv kev kho cov khoom qub lossis cov khoom qub. Rov qab engineering cov khoom tawg, tsim cov qauv siv quav ciab los ntawm 3D scan lossis ib feem qub, thiab khiav ib pawg me me los ntawm cov xuab zeb ploj ploj feem ntau yog tib txoj kev daws teeb meem. Nws khaws cov cuab yeej cuab tam qub. Qhov ntawd yog qhov ua tau zoo, tsis zoo, tab sis muaj txiaj ntsig zoo heev ntawm cov txheej txheem qub tsev kawm ntawv no. Nws tsis yog hais txog high-volume automation; nws yog hais txog saj zawg zog, txawj metalworking. Thiab qhov ntawd, kuv xav tias, yog dab tsi tau txhawb nqa kev ua haujlwm los ntawm ntau xyoo ntawm kev hloov pauv kev lag luam.
