Khoom Paub meej
Qhov tseem ceeb ntawm kev kub siab tuag casting yog ib txoj hauv kev los sau cov pwm tuag-casting pwm (tuag-casting pwm) kab noj hniav nrog cov kua lossis cov kua hlau semi-kua ntawm kev kub ceev nyob rau hauv qhov kev txiav txim siab, thiab tsim thiab solidifying nyob rau hauv siab kom tau. castings.
Kev kub siab casting txheej txheem
Layout ntawm kev kub siab casting
Tam sim no, cov kob tuag-casting dav dav yuav xav txog cov kev teeb tsa hauv qab no: lub tshuab tuag-casting yog nruab nrog lub tshuab nqus tsev, lub qhov cub tuav tau nruab nrog ntau qhov system casting, thiab cov txheej txheem txau yog yoog rau cov khoom kom luv lub sijhawm txau. . Cov neeg nqa khoom tuaj yeem ua tiav cov khoom thauj, tshem tawm cov hnab slag, thiab luam ntawv. Cov kob tuag-casting kuj tuaj yeem hloov kho kom tsis siv neeg tu thaum cov khoom ntim kuj loj.
Kev siv CAE simulation software
CAE tsom xam yog nce siv nyob rau hauv kev lag luam tuag casting, sawv cev los ntawm PROCAST, MAGMA, FLOW-3D, thiab lwm yam. Simulation: Raws li kev suav cov txiaj ntsig ntawm cov dej ntws, kev xa tawm nrawm, thiab lwm yam, peb tuaj yeem kwv yees qhov tsis xws luag xws li raws li huab cua entrainment, inclusions, thiab tsis zoo filling, uas zoo heev txhim kho tus nqi yield thiab txuag lub hom phiaj tus nqi heev. Nws yog ib qho cuab yeej muaj txiaj ntsig zoo kom sai thiab tshawb fawb tsim tag nrho cov txheej txheem casting (lub rooj vag, khiav, dej ntws, thiab lwm yam) ntawm cov pwm tuag-casting. Txhim kho cov txheej txheem tsis zoo ntawm cov txheej txheem casting, txo tus naj npawb ntawm cov khoom pwm sim, txo cov nqi casting, thiab txhim kho cov khoom zoo. Siv CAE software feem ntau txheeb xyuas kev sau, kev sib koom ua ke, kev faib tawm pore thiab tshaj tawm cov ntawv tshaj tawm.
Kev siv lub tshuab nqus tsev tuag casting
Nrog rau kev txhim kho txuas ntxiv ntawm cov khoom lag luam zoo, kev siv lub tshuab nqus tsev los daws cov teeb meem ntawm kev txhaws thiab huab cua nruj ntawm castings tau tsim tau zoo. Lub tshuab nqus tsev feem ntau siv lub tshuab nqus tsev vacuum. Feem ntau siv lub tshuab nqus tsev vacuum muaj ob lub qauv hauv qab no. Daim duab 3 yog daim duab schematic ntawm lub tshuab nqus tsev vacuum. Ib yam li cov txheej txheem tuag-casting zoo tib yam, tom qab molten aluminium nkag mus rau hauv lub siab chamber, lub tshuab nqus tsev pib. Tom qab ntawd thaum lub tshuab tuag-casting pib ntawm kev kub ceev, lub zog kinetic ntawm molten aluminium yog cia siab rau kov lub caij nplooj ntoos hlav nplooj ntawm lub tshuab nqus tsev valve. Thaum siv lub tshuab nqus tsev vacuum, feem ntau nws yuav tsum raug kaw thaum preheating pwm. Tom qab preheating tiav, kev kub ceev thiab kev txhawb nqa tuaj yeem pib ua ntej lub tshuab nqus tsev tuaj yeem siv. Cov tshuab nqus tsev vacuum yog qhov yooj yim siv, tab sis qhov tseeb ntawm lub tshuab nqus tsev yog siab, thiab tus nqi ntawm lub tshuab nqus tsev yog qhov siab. Daim duab 4 yog daim duab schematic ntawm lub tshuab nqus tsev hydraulic. Lub hauv paus ntsiab lus yog tib yam li lub tshuab nqus tsev vacuum valve. Thaum lub punch pib pib, lub tshuab nqus tsev pib, tab sis lub hauv paus ntsiab lus ntawm kev kaw lub tshuab nqus tsev vacuum yog txawv. Lub tshuab nqus tsev hydraulic feem ntau pib ua haujlwm ntawm kev kub ceev, thiab tib lub sijhawm tus qauv naj npawb raug xa mus rau hydraulic system ntawm lub tshuab nqus tsev valve, thiab lub tshuab nqus tsev vacuum kaw. Tus nqi ntawm lub tshuab nqus tsev hydraulic yog qhov tsawg, tab sis cov txheej txheem tuag-casting tsis thiab pwm tsim yuav tsum sib phim, txwv tsis pub cov dej txhuas yuav tuag-cam khwb cia rau hauv lub tshuab nqus tsev vacuum thiab ua rau txhaws.
Kev siv cov thev naus laus zis tshiab hauv cov tshuab tuag-casting
Lub tshuab nqus tsev siab tuag-casting tshuab
Tam sim no, cov tshuab tuag-casting tuaj txawv teb chaws yog sawv cev los ntawm Bühler thiab Fulai, thiab ob lub tshuab tuag-casting muaj lawv qhov tshwj xeeb hauv kev siv lub tshuab nqus tsev siab; Bühler lub tshuab nqus tsev siab yog tsim los kom tshem tawm lub siab chamber thiab pwm rov qab phaj. Lub interface ua kom yooj yim tshem tawm cov huab cua los ntawm lub siab chamber, thiab lub tshuab nqus tsev nyob rau sab nraub qaum ntawm pwm yog qhov tsim nyog rau kev nqus cov kab noj hniav kom zoo dua. Fulai lub tshuab nqus tsev siab ncaj qha kaw tag nrho lub siab chamber. Ib lub yeeb nkab yog tsim los rau hauv qab ntawm lub siab chamber kom ncaj qha mus rau hauv lub qhov cub tuav kom tiav cov sealing ntawm pwm. Cov kab noj hniav raug tshem tawm los tsim qhov tsis zoo siab kom tshem tawm cov txhuas hauv qhov cub tuav. Cov kua yog nqus mus rau hauv lub siab chamber thiab ces tuag-casted. Qhov zoo tshaj plaws ntawm cov thev naus laus zis no yog tias nws tsis txhob oxidation thiab slag inclusions thaum lub sij hawm sib cuag ntawm txhuas dej thiab cua, thiab tuaj yeem ua T6 kev kho cua sov. Nws twb tau tsim cov qauv tsim ntau rau cov tsheb hauv Tebchaws Europe.
Kev hloov pwm sai
Kev txhim kho kev tsim khoom thiab txo cov nqi tsim khoom yog lub hom phiaj ntawm txhua lub tuam txhab tsim khoom. Lub ntsiab txhais thoob ntiaj teb ntawm OEE yog: OEE yog lub ntsiab lus ntawm tag nrho cov cuab yeej siv tau zoo. Nws muaj peb yam tseem ceeb: muaj, kev ua tau zoo thiab qhov Performance index, uas yog: OEE=muaj X kev ua tau zoo X qhov Performance index. Rau kev tuag casting, pwm pauv yog ib qho ntawm rau qhov kev poob loj. Kev hloov pauv sai sai tau dhau los ua lub hom phiaj ua raws li kev tsim tawm ntshiv. Pwm pauv feem ntau txhais tau tias yog lub sijhawm los ntawm cov khoom tsim nyog kawg mus rau cov pwm tom ntej mus rau lub tshuab tuag-casting los tsim cov khoom tsim nyog thawj zaug; nyob rau hauv Nyiv, rau 800-tuj txias chamber tuag-casting Rau cov cav tov, lub sij hawm pauv pwm dav dav yog 10-20 feeb; nyob rau hauv Suav teb, lub sij hawm pauv pwm yog qhov ntev, thiab nws yog qhov ntau tshaj 10 teev. Ntxiv nrog rau kev sib pauv pwm cuam tshuam nrog kev tswj xyuas lub sijhawm, kev ua haujlwm ntawm tus qauv, thiab kev tswj cov cuab yeej, kev ntsuam xyuas seb cov xwm txheej ntawm pwm pauv tau ua raws li cov hauv qab no:
- (a) Txawm tias cov pwm tuaj yeem ntsia tau sai thiab muab tso rau
- (b) Txawm tias cov pwm tuaj yeem clamped sai sai (clamp lossis clamping ntsia hlau)
- (c) Seb tus qauv ejection ntawm lub tshuab tuag casting thiab pwm tuaj yeem txuas tau sai
- (d) Txawm hais tias cov tub ntxhais-rub lub tog raj kheej tuaj yeem txuas tau sai
- (e) Txawm hais tias lub tog raj kheej stroke teeb liab tuaj yeem txuas tau sai
- (f) Seb cov txheej txheem tsis tuaj yeem nyeem tau sai
- (g) Seb lub preheating modulus yog qhov qis tshaj plaws (siv lub pwm kub tswj los preheat pwm yog tias tsim nyog).
Kev kub siab tuag casting khoom
Tam sim no, aluminium alloy tuag-casting khoom feem ntau muab faib ua peb pawg raws li qhov ntau. Thawj qeb yog lub cav kis tau tus mob, lub tog raj kheej thaiv, thiab lwm yam uas sawv cev los ntawm lub tsheb, maus taus, thiab cov cav tsheb dav hlau. Cov qeb thib ob yog kev sib txuas lus hauv network. Cov neeg sawv cev ntawm lub hauv paus chaw nres tsheb plhaub, lim plhaub, thiab cov qeb thib peb yog cov khoom siv lub cev ntawm lub tsheb nrog cov kev xav tau kev ua haujlwm siab dua. Raws li pom nyob rau hauv daim duab, nws yog ib tug raug txhuas alloy tuag-casting khoom:
Aluminium alloy muaj cov khoom siv hluav taws xob zoo heev vim nws lub zog tshwj xeeb thiab zoo corrosion kuj. Hauv kev sib raug zoo ntawm kev txuag hluav taws xob, txo qis emissions, thiab kev tiv thaiv ib puag ncig ntsuab, aluminium alloy tuag-casting yog tsim sai heev hauv Suav teb. Nws ntseeg hais tias nyob rau hauv lub neej yav tom ntej, aluminium alloy khoom yuav muaj ntau thiab ntau haiv neeg.
