Cov qhov tseem ceeb ntawm cov hlau casting koom nrog nchuav hlau molten rau hauv pwm uas muaj cov kab noj hniav ntawm qhov xav tau, cia nws txias thiab khov. Cov txheej txheem tsim khoom qub no tseem tsis tau hloov pauv yog qhov tseem ceeb rau kev tsim cov geometry nyuaj uas nyuaj lossis tsis tuaj yeem ua tiav los ntawm kev ua haujlwm ib leeg. Los ntawm cov tsheb cav thaiv mus rau cov duab puab zoo nkauj, casting tseem yog lub hauv paus ntawm kev lag luam niaj hnub vim nws muaj peev xwm tuav tau ntau yam alloys thiab ntau lawm.
Dab tsi yog Cov Ntsiab Cai ntawm Hlau Casting?
Ntawm nws cov tub ntxhais, hlau casting yog cov txheej txheem tsim khoom uas cov khoom siv ua kua tau nkag mus rau hauv pwm. Cov qhov tseem ceeb ntawm cov hlau casting cia siab rau peb theem tseem ceeb: qauv tsim, pwm npaj, thiab qhov tseeb pouring thiab solidification ntawm hlau. Kev nkag siab txog cov hauv paus ntsiab lus no yog qhov tseem ceeb rau cov engineers thiab cov neeg tsim qauv txhawm rau txhawm rau txhim kho qhov ua tau zoo thiab kev ua haujlwm tau zoo.
Cov txheej txheem pib nrog ib tug qauv, uas yog ib tug replica ntawm qhov kawg khoom. Cov qauv no txiav txim siab cov duab ntawm kab noj hniav hauv pwm. Thaum cov pwm tau npaj siv cov ntaub ntawv xws li xuab zeb, ceramic, los yog hlau, molten alloy yog poured rau hauv. Raws li cov hlau txias, nws shrinks me ntsis, ib qho tseem ceeb uas yuav tsum tau suav rau thaum lub sij hawm tsim qauv kom paub meej qhov tseeb.
Cov kws tshaj lij kev lag luam lees paub tias kev paub txog cov peev txheej no tso cai rau kev tswj hwm zoo dua ntawm microstructure thiab cov khoom siv tshuab. Txawm hais tias tsim ib qho qauv los yog ntau txhiab units, cov hauv paus ntsiab lus tseem ceeb nyob ib puag ncig, txawm hais tias cov txheej txheem tshwj xeeb yuav txawv raws li qhov xav tau thiab qhov ntim.
Step-by-Step Hlau Casting txheej txheem
Kom tag nrho cov qhov tseem ceeb ntawm cov hlau casting, ib tug yuav tsum nkag siab txog cov haujlwm ua ntu zus cuam tshuam. Txawm hais tias cov txheej txheem tshwj xeeb txawv, qhov kev ua haujlwm dav dav ua raws li qhov kev xav tau los ntawm kev tsim mus rau qhov kawg. Txhua kauj ruam yuav tsum tau ua tib zoo saib xyuas kom meej kom tsis txhob muaj qhov tsis xws luag xws li porosity, shrinkage, lossis txias kaw.
1. Qauv Ua
Txoj kev taug pib nrog kev tsim qauv. Cov qauv no tuaj yeem ua los ntawm cov ntoo, yas, lossis hlau, nyob ntawm seb qhov loj me ntawm cov khoom siv. Cov qauv no suav nrog cov khoom siv ntxiv hu ua "pab nyiaj" los them rau cov hlau shrinkage thaum txias. Nws kuj tseem muaj cov kaum sab xis kom yooj yim tshem tawm ntawm cov pwm yam tsis muaj kev puas tsuaj rau phab ntsa kab noj hniav.
2. Kev npaj pwm
Thaum tus qauv npaj txhij, nws yog siv los tsim cov pwm. Hauv cov xuab zeb casting, feem ntau txoj kev, cov qauv tau ntim rau hauv cov xuab zeb tshwj xeeb sib xyaw nrog cov binders. Cov pwm muaj ob halves: lub cope (sab saum toj) thiab luag (hauv qab). Lub rooj vag system yog carved los yog tsim los coj cov hlau molten mus rau hauv kab noj hniav thaum cuab impurities.
3. Melting thiab Pouring
Cov hlau uas xaiv tau yog melted nyob rau hauv lub cub tawg ntawm qhov kub thiab txias rau nws muaj pes tsawg leeg. Piv txwv li, aluminium melts ntawm qhov kub qis dua hlau. Thaum cov hlau mus txog qhov tseeb fluidity, nws yog poured rau hauv pwm los ntawm lub rooj vag system. Lub sij hawm thiab kev tswj qhov kub thiab txias yog qhov tseem ceeb ntawm no los xyuas kom meej tias cov hlau ntim tag nrho cov kab noj hniav ua ntej solidifying.
4. Cua txias thiab Solidification
Tom qab pouring, cov hlau yuav tsum txias undisturbed. Tus nqi ntawm cov cua txias cuam tshuam rau cov qauv nplej ntawm cov hlau, uas ncaj qha cuam tshuam nws lub zog thiab ductility. Kev ua kom txias sai tuaj yeem ua rau cov txheej txheem nyuaj tab sis nkig, thaum txias qeeb txhawb nqa cov nplej loj dua thiab ua haujlwm zoo dua. Cov qhov tseem ceeb ntawm cov hlau casting dictate tias theem no yog tswj kom tau raws li cov neeg kho tshuab specifications.
5. Ntxig thiab ntxuav
Thaum solidified, lub casting raug tshem tawm los ntawm pwm, txheej txheem hu ua shakeout. Cov khoom nyoos, feem ntau hu ua "ntsuab casting," tseem muaj cov rooj vag, cov neeg khiav dej num, thiab cov risers. Cov khoom siv ntau dhau no raug txiav tawm, thiab qhov saum npoo yog ntxuav ntawm blasting lossis sib tsoo kom tshem tawm cov xuab zeb seem lossis nplai.
6. Kev tshuaj xyuas thiab ua tiav
Cov kauj ruam kawg suav nrog kev tshuaj xyuas nruj kom pom cov teeb meem sab hauv lossis qhov chaw. Cov txuj ci zoo li X-ray radiography, dye penetrant testing, los yog kev soj ntsuam ultrasonic feem ntau yog ua haujlwm. Yog hais tias ib feem dhau los ntawm kev tswj kom zoo, nws dhau los ua qhov kawg machining lossis kev kho cua sov kom ua tiav qhov kev ua siab ntev thiab cov khoom.
- Qauv Tsim: Tsim lub replica nrog shrinkage nyiaj pab.
- Pwm Tsim: Tsim qhov chaw tsis zoo siv xuab zeb, ceramic, lossis hlau.
- Melting: Cua sov lub alloy mus rau lub xeev cov kua.
- Ncuav: Hloov cov hlau molten rau hauv pwm kab noj hniav.
- Solidification: Tso cai tswj kom txias kom teeb tsa cov duab.
- Ua tiav: Tshem tawm cov khoom siv ntau dhau thiab tshuaj xyuas kom zoo.
Hom Txheej Txheem Casting
Thaum lub qhov tseem ceeb ntawm cov hlau casting yog universal, qhov kev ua tiav txawv heev raws li cov txheej txheem siv. Cov txheej txheem sib txawv muaj qhov zoo sib txawv ntawm qhov chaw tiav, qhov tseeb qhov tseeb, thiab kev ua haujlwm nrawm. Xaiv txoj hauv kev yog qhov kev txiav txim siab tseem ceeb hauv kev tsim khoom.
Xuab zeb Casting
Xuab zeb casting yog txoj kev siv dav tshaj plaws hauv ntiaj teb, suav rau feem ntau ntawm txhua qhov kev tsim tawm. Nws siv silica xuab zeb sib xyaw nrog cov binders los tsim cov pwm. Cov txheej txheem no yog ntau yam, muaj peev xwm ua tau qhov chaw xws li ob peb ooj mus rau ob peb tons. Nws yog qhov tshwj xeeb tshaj yog nyiam rau cov khoom loj xws li cov cav cav thiab cov twj tso kua mis uas cov cuab yeej siv yuav tsum tau khaws cia qis.
Lub ntsiab zoo ntawm cov xuab zeb casting yog nyob rau hauv nws yooj. Yuav luag txhua cov hlau alloy tuaj yeem nrum siv txoj kev no, suav nrog hlau, hlau, txhuas, thiab tooj liab. Txawm li cas los xij, qhov ua tiav saum npoo yog feem ntau rougher piv rau lwm txoj hauv kev, feem ntau xav tau kev siv tshuab ntxiv. Cov pwm feem ntau raug rhuav tshem tom qab siv txhua qhov, ua rau nws zoo tagnrho rau cov khoom ntim qis rau nruab nrab.
Tuag Casting
Tuag casting yuav tsum yuam molten hlau nyob rau hauv siab siab mus rau hauv ib tug reusable hlau pwm, hu ua tuag. Cov txheej txheem no yog tshwj xeeb tshaj yog ceev thiab ua qhov chaw nrog zoo heev dimensional raug thiab du nto finishes. Nws yog feem ntau siv rau cov hlau tsis muaj hlau xws li zinc, aluminium, thiab magnesium.
Vim tias cov tuag yog kim los tsim, tuag casting yog kev lag luam tsuas yog rau cov khoom ntim ntau lawm. Kev kub siab ua kom ntseeg tau tias cov hlau ua tiav txawm tias cov seem thinnest ntawm cov pwm, tso cai rau cov geometries nyuaj nrog nruj tolerances. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov neeg siv khoom siv hluav taws xob hauv tsev thiab tsheb sib kis.
Kev nqis peev Casting
Kuj hu ua ploj-wax casting, peev casting muaj superior precision thiab nto zoo. Cov txheej txheem pib nrog ib tug wax qauv coated nyob rau hauv ib tug ceramic slurry los tsim ib lub plhaub. Thaum lub plhaub hardens, siv quav ciab yog melted, tawm hauv ib tug meej kab noj hniav. Molten hlau yog ces poured rau hauv no ceramic pwm.
Txoj kev no tshem tawm qhov xav tau ntawm cov kab sib cais, uas ua rau cov khoom nyob ze-net-puab cov khoom uas yuav tsum muaj tsawg kawg nkaus tom qab ua tiav. Nws yog dav siv nyob rau hauv aerospace rau turbine hniav thiab hauv kev kho mob kev lag luam rau cov cuab yeej phais. Thaum tus nqi ntau dua ib chav tsev dua li xuab zeb casting, nws txo cov nqi tsim khoom tag nrho los ntawm kev txo lub sijhawm ua haujlwm.
Permanent Pwm Casting
Cov pwm tas mus li casting siv cov pwm tuaj yeem siv tau los ntawm cov hlau, feem ntau yog hlau lossis hlau. Tsis zoo li tuag casting, lub ntiajteb txawj nqus los yog tsis tshua muaj siab yog feem ntau yog siv los sau cov pwm es tsis txhob siv high-pressure txhaj. Qhov no ua rau cov qauv zoo dua qub thiab txhim kho cov cuab yeej cuab tam piv rau cov xuab zeb casting.
Cov txheej txheem no cuam tshuam qhov sib npaug ntawm cov cuab yeej siv qis ntawm cov xuab zeb casting thiab qhov siab ntawm qhov tuag casting. Nws yog tsim rau nruab nrab-rau-siab ntim ntau lawm ntawm txhuas thiab tooj liab alloy qhov chaw. Cov ntawv siv feem ntau suav nrog lub log tsheb, pistons, thiab manifold Cheebtsam.
