Tuag-casting txhuas qhov chaw yog ib qho zoo heev hlau txoj kev. Nws yog ib txoj hauv kev kom ua tiav cov chips tsawg dua thiab tsis muaj chips. Nws yog dav siv thiab tsim sai heev. Phab ntsa tuab ntawm txhuas qhov chaw (feem ntau hu ua phab ntsa tuab) yog qhov tseem ceeb ntawm qhov tseem ceeb hauv cov txheej txheem pwm tuag. Phab ntsa thickness yog ze ze rau tag nrho cov txheej txheem specification, xws li xam lub sij hawm sau, xaiv innate ceev, thiab xam lub sij hawm solidification. , Kev tshuaj xyuas qhov ntsuas kub ntawm cov pwm, cov nyhuv ntawm qhov siab (qhov kawg tshwj xeeb siab), qhov ntev ntawm pwm tuav lub sij hawm, qhov kub ntawm qhov ejection ntawm casting, thiab kev khiav hauj lwm ceev, thiab lwm yam.
Tam sim no, kev tuag-casting alloys tsis txwv rau cov hlau tsis muaj hlau xws li zinc, aluminium, magnesium, thiab tooj liab, thiab maj mam nthuav dav los siv rau kev tuag-casting cam khwb cia hlau thiab hlau castings. Qhov loj thiab qhov hnyav ntawm qhov tuag-casting aluminium yog nyob ntawm lub zog ntawm lub tshuab tuag-casting. Raws li lub zog ntawm lub tshuab tuag-casting tseem nce ntxiv, qhov loj ntawm cov casting tuaj yeem nyob ntawm ob peb millimeters mus rau 1-2m; qhov hnyav tuaj yeem nyob ntawm ob peb grams mus rau kaum kilograms. Nws tuaj yeem tuag-cam khwb cia txhuas qhov chaw nrog txoj kab uas hla ntawm 2m thiab qhov hnyav ntawm 50kg. Hauv kev tuag casting, dab tsi yog qhov cuam tshuam ntawm phab ntsa tuab ntawm txhuas tuag castings ntawm ntau qhov sib txawv?
Cov nyhuv ntawm cov phab ntsa tuab dhau ntawm aluminium tuag casting
- Qhov zoo ntawm qhov chaw: Yog tias cov phab ntsa tuab ntawm aluminium tuag castings yog tuab heev, qhov zoo ntawm qhov chaw yuav tsis zoo, thiab qhov tsis xws li cov tsos ntxhib, burrs, thiab npuas yuav tshwm sim ntau zaus, uas tsis tuaj yeem ua tau raws li qhov xav tau ntawm qhov xav tau zoo.
- Txo lub zog tensile: Yog tias cov phab ntsa thickness ntawm txhuas tuag casting yog tuab dhau lawm, lub zog tensile ntawm cov khoom yuav txo qis, vim hais tias cov khoom siv txhuas pom tias muaj kev nyiam rau cov yas deformation, thiab cov thickness ntau dua, qhov kev txo qis ntxiv ntawm cov khoom muaj nyob hauv cov khoom siv. cov khoom siv aluminium.
- Kev ua haujlwm tsis zoo: Yog tias cov phab ntsa tuab ntawm aluminium tuag casting yog tuab heev, kev ua haujlwm nyuaj yuav nce ntxiv, vim tias cov khoom siv aluminium uas tuab dhau yog nyuaj rau txiav los ntawm lub tshuab.
- Ua kom cov khoom hnyav: Ntau phab ntsa tuab ntawm txhuas tuag castings tseem yuav ua rau cov khoom hnyav ntxiv, uas yuav cuam tshuam rau tus nqi ntawm kev thauj mus los, siv, thiab tu cov khoom.
Vim qhov loj thermal expansion coefficient ntawm cov khoom siv txhuas, cov phab ntsa tuab heev ntawm txhuas tuag castings yuav ua rau cov thermal expansion tsis sib xws, ua rau cov khoom deform, warp, los yog tawg.
Cov nyhuv ntawm cov phab ntsa tuab heev ntawm aluminium tuag casting
Aluminium tuag castings nrog cov phab ntsa nyias dhau tuaj yeem cuam tshuam tsis zoo rau lawv lub zog thiab kav ntev. Phab ntsa thicknesses uas nyias dhau tuaj yeem ua rau qhov chaw warp, tawg lossis warp yooj yim, yog li ua rau lub neej luv. Tsis tas li ntawd, cov phab ntsa tuab dhau lawm tseem yuav ua rau muaj teeb meem zoo hauv kev ua thiab tsim cov txhuas tuag castings.
Yog tias cov phab ntsa tuab dhau lawm, aluminium tuag castings yuav raug cuam tshuam rau sab nrauv thiab extrusion, thiab yog li ntau dua rau deformation thiab tawg. Tsis tas li ntawd, cov phab ntsa tuab dhau lawm yuav cuam tshuam rau qhov zoo ntawm aluminium tuag castings thiab ua rau muaj qhov tsis xws luag. Tag nrho cov xwm txheej no tuaj yeem ua rau cov khoom yuav tsum tau hloov thiab kho ntau zaus, ua rau cov nqi poob qis thiab kev saib xyuas.
Yog li ntawd, thaum cuam tshuam nrog txhuas tuag castings, phab ntsa thickness yuav tsum nruj me ntsis tswj kom ua tau raws li qhov yuav tsum tau tsim thiab txo qhov hnyav ntau npaum li sai tau thaum ua kom muaj zog.
Phab ntsa Thickness Standards rau Aluminium Tuag Castings
Cov phab ntsa tuab txheej txheem ntawm txhuas tuag castings feem ntau yog raws li cov yam ntxwv xws li kev tsim qauv, cov txheej txheem txheej txheem, thiab cov khoom siv alloy. Feem ntau, qhov tsawg kawg nkaus phab ntsa thickness ntawm txhuas tuag castings yuav tsum xyuas kom meej nws lub zog, rigidity, thiab sealing kev ua tau zoo, thiab coj mus rau hauv tus account yam xws li thermal deformation thiab shrinkage thaum lub sij hawm casting txheej txheem.
Tshwj xeeb, qhov tsawg kawg nkaus phab ntsa tuab ntawm txhuas tuag castings feem ntau yuav tsum yog 1 hli, tab sis qhov tseeb phab ntsa thickness yuav tsum tau txiav txim siab los ntawm cov khoom xws li cov qauv tshwj xeeb thiab cov khoom siv. Yog tias cov phab ntsa tuab dhau lawm, nws yuav ua rau muaj teeb meem xws li qhov tsis xws luag, deformation, tawg, thiab insufficiency hauv casting; ntawm qhov tsis sib xws, yog tias phab ntsa thickness yog tuab heev, nws yuav ua rau tus nqi nce, nce qhov hnyav thiab cuam tshuam rau kev tsim khoom thiab lwm yam.
Yam tsawg kawg nkaus phab ntsa thickness rau aluminium casting
Qhov tsawg kawg nkaus phab ntsa ntawm aluminium tuag castings feem ntau yuav tsum khaws cia ntawm li 1.5 hli. Qhov no yog vim lub siab fluidity thiab solidification shrinkage ntawm txhuas alloys, thiab ib tug nyias nyias profile yuav tsum tau tshwj tseg thaum lub sij hawm casting los xyuas kom meej zoo castings. Nyob rau tib lub sijhawm, xav txog cov khoom siv thiab cov qauv tsim ntawm cov casting, qee zaum qhov tsawg kawg nkaus phab ntsa thickness kuj yuav tsum tau kho raws li qhov xwm txheej tshwj xeeb.
Nyob rau hauv luv luv, cov txheej txheem phab ntsa tuab ntawm txhuas tuag castings yuav tsum tau soj ntsuam xyuas thiab txiav txim raws li qhov xwm txheej tshwj xeeb, thiab tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum ua raws li cov txheej txheem casting specifications thiab cov khoom yuav tsum tau ua kom tau qhov zoo tshaj plaws casting nyhuv.
