Low-Pressure Tuag Casting

Khoom Paub meej

Low-Pressure Die Casting yog cov cuab yeej siv hlau siv los tsim ntau yam khoom siv hlau. Nws suav nrog nchuav hlau molten nyob rau hauv siab rau hauv pwm kaw. Cov txheeb ze rau kev kub siab tuag casting, txoj kev no feem ntau yog siv qis dua, uas ua rau cov hlau sau cov pwm qeeb dua.

Cov txheej txheem no yog txheej txheem nqus dej ntws. Feem ntau, cov hlau dhau los ntawm lub xeev ua kua, sau cov pwm los ntawm lub ntiajteb txawj nqus. Hauv qab ntawm pwm yog txuas nrog lub cub tawg lossis lub cub tawg, uas muab lub siab xav tau ntawm cov hlau.

Tsawg-siab tuag casting lub zog feem ntau yuav tsum tau sau lub sijhawm ntev dua li cov pa hluav taws xob ntau dua, tab sis nws tau txhais tau ntau dua sab hauv cov khoom lag luam yog ruaj khov dua thiab muaj ntau dua. siab.

lpdc tuag casting txheej txheem

Low-pressure casting yog txheej txheem rau kev tsim cov castings nyob rau hauv lub siab ntawm filling kua hlau. Cov txheej txheem suav nrog cov kauj ruam hauv qab no:

• Kev Npaj Pwm: Cov pwm xav tau kev npaj, suav nrog kev tu, ziab, thiab preheating.
• Cua sov ntawm Cov Khoom Siv Txhuas Txhuas: Ua kom sov cov khoom siv txhuas ua kom sov rau qhov tsim nyog, feem ntau ntawm 600-700 degree .
• Pouring of Liquid Aluminium rau hauv Pwm Cavity: Nyob rau hauv cov cua kub, ncuav cov kua txhuas tsis tu ncua mus rau hauv pwm kab noj hniav los ntawm ib tug riser.
• Kev Txhaj Tshuaj Txhaum Cai: Khaws cov roj siab ntawm cov kua dej hauv lub qhov cub thiab txhaj cov kua txhuas rau hauv pwm kab noj hniav kom txog thaum nws puv.
• Solidification ntawm Aluminium Parts: Thaum lub sij hawm, cov kua txhuas maj mam solidifies rau hauv castings.
• Pwm Qhib: Tom qab ua tiav kev ua tiav ntawm kev ua tiav, tso cov pa roj rau ntawm cov kua dej, tso cai rau cov hlau tsis muaj zog hauv cov riser ntws rov qab mus rau lub crucible. Tom qab ntawd, lub tog raj kheej qhib lub pwm thiab thawb tawm lub casting.

Tsawg-pressure casting yog tus cwj pwm los ntawm kev ua haujlwm siab thiab muaj peev xwm los tsim cov khoom siv high-precision aluminium. Nws yog tshwj xeeb tshaj yog tsim rau kev tsim precision castings, nyias-walled aluminium alloy castings, thiab loj aluminium alloy castings.

Low-pressure casting yog ib txoj kev casting uas tso cai rau cov kua hlau ua kom tiav cov txheej txheem ntawm cov kab noj hniav thiab solidifying nyob rau hauv siab kom tau castings. Vim tias lub siab siv tsawg (20 ~ 60kPa), nws yog hu ua low-pressure casting. Cov txheej txheem yog raws li nram no: Nyob rau hauv lub kaw crucible (los yog kaw lub tank), qhuav compressed cua yog qhia. Nyob rau hauv qhov kev txiav txim ntawm roj siab, cov kua hlau nce raws cov yeeb nkab riser mus rau hauv lub sprue, ntseeg nkaws nkag mus rau hauv pwm los ntawm cov kab noj hniav sab hauv, thiab tswj cov roj siab ntawm cov kua nto hauv lub crucible kom txog thaum lub casting yog tag nrho solidified. Tom qab ntawd cov roj siab ntawm cov kua dej tso tawm, tso cai rau cov kua tsis muaj hlau tsis huv hauv cov kua riser kom ntws rov qab mus rau hauv lub crucible, thiab tom qab ntawd cov pwm qhib thiab muab tshem tawm.

Qhov zoo ntawm tsis tshua muaj siab casting 

1. Muaj cov pa roj tsawg thiab cov khib nyiab cuam tshuam, lub zog ceev tuaj yeem hloov pauv, thiab cov kua zaub molten tau sau los ntawm laminar ntws.
2. Siv hauv qab txhaj tshuaj pwm filling, cov hlau molten tau ua kom zoo tsis muaj txaws, uas tuaj yeem zam kev cuam tshuam cov roj thiab yaig ntawm cov pwm phab ntsa thiab cov tub ntxhais thiab txhim kho qhov tsim nyog tus nqi ntawm castings.
3. Lub casting crystallizes nyob rau hauv siab. Cov qauv casting yog ntom, cov txheej txheem yog qhov tseeb, qhov saum npoo yog du, thiab cov khoom siv tshuab yog siab. Nws yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau kev casting ntawm qhov loj thiab nyias-walled qhov chaw.
4. Lub pressurization ceev yuav hloov tau, thiab cov kua zaub molten yog sau los ntawm laminar txaus.
5. Cov ntaub ntawv tuaj yeem siv rau hauv ntau hom kev siv

Disadvantages ntawm tsis tshua muaj siab casting

1. The production efficiency is low compared with gravity die casting. Die Casting>Gravity>Tsawg Siab
2. Lub voj voog casting yog ntev, thiab cov khoom tsim tau tsis zoo. Yuav kom tswj tau cov kev taw qhia solidification thiab yaj fluidity, pwm kub yog siab thiab lub solidification ceev yog qeeb.
3. Cov qauv nyob ze ntawm lub rooj vag yog tuab dua, thiab cov khoom siv kho tshuab ntawm qhov chaw qis qis tsis siab, yuav tsum muaj kev tswj hwm thiab nruj (kub, siab, thiab lwm yam)

Qhov twg yog qhov zoo dua, qis-siab casting lossis xuab zeb casting?

Low-pressure casting thiab xuab zeb casting txhua tus muaj lawv tus kheej zoo thiab daim ntawv thov scenarios. Low-pressure casting yog feem ntau haum rau tsim complex-shaped hlau qhov chaw nrog ntau dua engineering zog. Nws tuaj yeem tsim tau ntau dua, denser castings thiab feem ntau muaj qis porosity. Cov txheej txheem no yog tsim rau cov teb uas yuav tsum tau muaj ntau yam ntawm high-precision, high-zoo qhov chaw, xws li automotive qhov chaw, aerospace qhov chaw, thiab lwm yam.

Nyob rau hauv sib piv, xuab zeb casting yog ntau saj zawg zog thiab nqi-zoo thiab yog haum rau me me batch ntau lawm los yog loj qhov chaw nrog cov duab yooj yim. Txoj kev casting no muaj cov txheej txheem yooj yim thiab tus nqi qis, tab sis feem ntau nws tsis tuaj yeem tsim cov khoom siab heev.

Yog li ntawd, txoj kev casting twg yog qhov zoo dua nyob ntawm lub hom phiaj ntawm qhov yuav tsum tau ua, qhov kev xav tau zoo, thiab qhov ntau lawm.

Low-pressure casting thiab gravity casting

Tsawg-pressure casting thiab gravity casting yog ob txoj kev casting sib txawv, thiab lawv muaj qee qhov sib txawv ntawm qhov zoo ntawm casting zoo, ntau lawm efficiency, txheej txheem complexity, thiab daim ntawv thov scenarios.

1. Casting Quality: Lub ntiajteb txawj nqus casting cia siab rau nws tus kheej qhov hnyav ntawm cov hlau molten los sau cov pwm kab noj hniav, uas ua rau qis qis dua thiab qhov zoo ntawm cov castings piv rau qhov tsis tshua muaj siab casting, uas ua tiav ntau dua precision.
2. Kev Ua Haujlwm Ntau Lawm: Lub ntiajteb txawj nqus casting feem ntau muaj kev ua haujlwm ntau dua piv rau qis-siab casting. Lub ntiajteb txawj nqus casting tuaj yeem tsim ntau cov castings hauv ib lub voj voog, ua kom nws ua haujlwm zoo dua.
3. Txheej txheem complexity: Tsawg-pressure casting yog ib tug complex txheej txheem piv rau lub ntiajteb txawj nqus casting. Nws koom nrog kev siv cov cuab yeej xws li cua sov rauv, lub tshuab nqus tsev siab, thiab cov tshuab pneumatic thiab yuav tsum tau tswj xyuas qhov ntsuas qhov ntsuas kub thiab siab, ua rau cov txheej txheem ntau dua.Gravity casting, ntawm qhov tod tes, yog qhov yooj yim dua thiab tsuas yog xav tau ib qho pwm thiab casting khoom.
4. Daim ntawv thov Scenario: Lub ntiajteb txawj nqus casting yog ib txwm casting txoj kev uas muaj ntau yam kev siv uas haum rau ntau hom casting ntau lawm.

Low-pressure casting, vim nws cov high-casting zoo thiab efficiency, tshwj xeeb tshaj yog zoo haum rau loj-scale ntau lawm yuav tsum tau.

Nyob rau hauv cov ntsiab lus, low-pressure casting thiab gravity casting txhua tus muaj lawv tus kheej cov yam ntxwv, thiab kev xaiv ntawm casting txoj kev nyob ntawm tej yam kev xav tau thiab daim ntawv thov scenarios.

Tsawg kawg siab rau tuag casting

1. Cov khoom siv: Cov hlau sib txawv yuav tsum muaj qhov sib txawv tuag casting siab. Piv txwv li, aluminium alloys yuav xav tau qis dua li magnesium alloys.
2. Khoom Geometry: Cov duab sib txawv thiab qhov ntau thiab tsawg ntawm cov khoom yuav xav tau kev sib txawv los xyuas kom meej qhov puv ntawm pwm.
3. Pwm Tsim: Cov qauv tsim pwm kuj tseem cuam tshuam rau qhov tsawg kawg nkaus qhov xav tau.

Feem ntau, qhov tsawg kawg nkaus siab feem ntau xav tau rau kev tuag casting tej zaum yuav txawv ntawm ob peb puas bar mus rau ntau txhiab tus tuav, tab sis tus naj npawb pes tsawg yuav txawv raws li cov ntsiab lus hais saum toj no. Piv txwv li, nyob ib ncig ntawm 200 bar (2 MPa) tej zaum yuav xav tau nyob rau hauv qee kis, thaum lub zog siab dua yuav tsum tau nyob rau lwm qhov.

Daim ntawv thov

Tsawg-siab tuag casting feem ntau yog siv los tsim loj-scale, structurally complex hlau alloy qhov chaw, xws li automotive qhov chaw, maus taus qhov chaw, engineering machinery qhov chaw, thiab qhov chaw nyob rau hauv lub aerospace teb. Tus txheej txheem no zoo tagnrho rau kev tsim cov khoom uas xav tau ntom ntom ntom ntom, thiab khav theeb thiab sab hauv kev ntxhov siab. Nws tsim cov khoom uas feem ntau muaj lub zog siab thiab ua haujlwm ntev thiab tuaj yeem ua tau raws li cov qauv tsim tshwj xeeb los ntawm cov hlau ntws thiab cov txheej txheem sau.
