Tuag casting yog txheej txheem hlau casting uas tsim cov khoom hlau nrog nruj tolerances thiab siab precision. Nws yog cov txheej txheem tsim khoom siv tau zoo thiab raug nqi siv hauv ntau qhov kev lag luam xws li aerospace, tsheb, kev kho mob, thiab lwm yam. Yog li yuav ua li cas tuag casting ua hauj lwm, cia peb paub ua ke.
1. Pwm
Cov txheej txheem tuag-casting yog txhaj cov hlau molten rau hauv pwm kab noj hniav nyob rau hauv siab. Lub pwm kab noj hniav, tseem hu ua pwm, feem ntau yog ua los ntawm cov hlau, muaj ob sab uas yog bolted ua ke thiab muaj cov duab uas xav tau ntawm qhov yuav tsum tau ua. Molten hlau yog txhaj rau hauv kab noj hniav los ntawm lub rooj vag tsim los xyuas kom meej txaus txaus thiab txhaws ntawm pwm.
Cov txheej txheem txhaj tshuaj yog tswj los ntawm lub tshuab hu ua lub tshuab tuag-casting. Lub tshuab tuav cov pwm nyob rau hauv qhov chaw thiab siv siab siab txog li 4, 000 psi los txhaj cov hlau molten rau hauv pwm. Thaum cov hlau tau ua tiav tag nrho cov kab noj hniav, lub siab raug tswj xyuas ob peb vib nas this kom paub meej tias cov khoom tau ruaj khov thiab npaj tau tawm.
Cov txheej txheem demolding yuav tsum cais ob halves ntawm pwm thiab thawb ib feem tawm ntawm kab noj hniav. Tom qab ntawd lub casting yog txiav tawm cov khoom siv ntau dhau thiab npaj rau kev ua haujlwm thib ob xws li pleev xim, plating, lossis sib dhos.
2. Kev sib piv kom zoo dua
Cov txheej txheem tuag-casting muaj ntau yam zoo dua lwm cov txheej txheem hlau-casting. Nws muaj peev xwm ua tau cov duab complex nrog ib tug du nto tiav thiab siab qhov tseeb. Nws tseem yog cov txheej txheem ua haujlwm siab heev, txhais tau tias nws tuaj yeem siv rau hauv cov khoom ntim ntau ntawm cov nqi qis.
3. Hom Tuag Casting
Cov txheej txheem tuag-casting tau muab faib ua peb hom: kub chamber tuag casting, txias chamber tuag casting, thiab lub tshuab nqus tsev tuag casting.
Kub chamber tuag casting yog siv rau tsawg melting point hlau xws li zinc, magnesium, thiab lead. Thaum lub sij hawm tus txheej txheem no, lub tshuab txhaj tshuaj yog submerged nyob rau hauv ib da dej ntawm molten hlau, muab ib tug nruam mov hlau rau txhua txhaj tshuaj.
Cold chamber tuag casting yog siv rau siab melting point hlau xws li txhuas, tooj dag, thiab tooj liab. Nyob rau hauv cov txheej txheem no, cov txheej txheem txhaj tshuaj yog sib cais los ntawm lub melting rauv, thiab cov hlau molten yog scooped rau hauv lub txhaj tshuaj chamber.
Lub tshuab nqus tsev tuag casting yog cov txheej txheem tshwj xeeb siv los tsim cov khoom nrog kev ncaj ncees thiab qhov chaw tiav. Thaum lub sij hawm tus txheej txheem no, cov pwm kab noj hniav raug tshem tawm ua ntej txhaj tshuaj kom tshem tawm cov cua ntxiab uas tuaj yeem ua rau cov porosity lossis cov hnab ntim cua hauv qhov ua tiav.
4. Kev ua haujlwm tuag-casting
Tuag casting yog ib qho txiaj ntsig zoo thiab raug nqi hlau casting txheej txheem uas tau siv dav hauv ntau yam lag luam. Los ntawm kev siv lub zog txhaj tshuaj molding molten hlau rau hauv cov duab nyuaj nrog kev ua haujlwm siab, tuag casting muaj ntau yam zoo dua lwm cov txheej txheem casting. Nws yog qhov tseem ceeb rau kev tsim khoom niaj hnub, ua kom zoohlau tuag-cast qhov chawnrog precision thiab kev ntseeg tau zoo ib yam.
