Nyob rau hauv niaj hnub kev lag luam ntau lawm, aluminium alloy tuag-casting qhov chaw tau dhau los ua ib qho ntawm cov khoom tseem ceeb thiab tau siv dav hauv kev tsim khoom thiab lub neej. Cov tsos zoo, raws li ib qho ntawm cov qauv tseem ceeb rau aluminium alloy tuag castings, kuj tseem ceeb heev. Txawm li cas los xij, vim yog cov txheej txheem pwm kab noj hniav thiab cov txheej txheem kub thiab cov txheej txheem ntau lawm, qhov tsis xws luag ntawm txhuas tuag-casting qhov chaw yog qhov nyuaj los zam. Yog li, yuav ua li cas aluminium die-casting manufacturers tswj qhov chaw ntawm qhov chaw tuag-casting los ntawm optimizing pwm?
Qhov chaw tsis xws luag ntawm txhuas tuag castings yog feem ntau cuam tshuam nrog kev tsim pwm. Cov qauv pwm tsim nyog tuaj yeem tswj tau cov txheej txheem casting zoo dua, txhim kho qhov tsis xws luag, thiab txo cov nqi ua haujlwm tom qab thiab kev siv zog ntau.
Kev tsim cov pwm tsis tsuas yog cuam tshuam rau cov duab thiab qhov loj ntawm cov casting tab sis kuj ncaj qha cuam tshuam rau lub xeev ntws ntawm cov tshuaj aluminium alloy thaum txhaj tshuaj thiab tus cwj pwm shrinkage thaum lub sij hawm txias thiab solidification. Mechanical engineers yuav tsum tau mus los ntawm ib tug series ntawm complex xam thiab soj ntsuam los txiav txim seb lub zoo pwm qauv kom ua tau raws li qhov yuav tsum tau nto zoo qauv ntawm txhuas tuag castings.
Ua ntej tshaj plaws, kev tsim pwm yuav tsum ua raws li peb qhov kev sib txuas ntawm "sau, solidification, thiab txias". Cov theem filling yog hais txog cov txheej txheem ntawm cov kua hlau nkag mus rau hauv pwm kab noj hniav, thaum lub sij hawm solidification theem yog hais txog cov txheej txheem ntawm cov kua hlau ua cov khoom txhuas alloy hauv pwm.
Thaum lub sij hawm ob theem no, kev tsim cov qauv pwm yuav tsum tau ua raws li cov hauv qab no rau hauv kev txiav txim siab:
- Flow field yam ntxwv: Flow field yam ntxwv muaj feem xyuam rau qhov khiav, ceev, nro, thiab distortion ntawm cov kua hlau thaum nws yog txhaj rau hauv pwm kab noj hniav, thiab yuav ua rau muaj kev cuam tshuam rau cov alloying thiab grain loj ntawm txhuas alloy. Yog li ntawd, cov qauv pwm yuav tsum xyuas kom meej tias cov tshuaj tuaj yeem ua tiav cov pwm kab noj hniav thiab xyuas kom meej tias qhov sib txawv ntawm cov kua hlau hauv pwm kab noj hniav yog ib yam thiab tsis tu ncua.
- Thaum tshav kub kub hloov: Cov theem solidification yog hais txog cov txheej txheem ntawm cov kua hlau ua ib qho khoom txhuas alloy hauv pwm. Nyob rau hauv cov txheej txheem no, nws yog ib qho tsim nyog yuav tau xav txog yuav ua li cas cov cua sov ntawm cov cua txias hauv cov kua hlau hloov mus rau pwm. Yog li ntawd, cov qauv pwm yuav tsum muaj peev xwm txo tau qhov kub thiab txias qhov sib txawv, kom cov aluminium alloy txias thiab solidifies kuj uniformly thoob plaws hauv pwm, tsis txhob muaj kev ntxhov siab nyob rau hauv tsub zuj zuj thiab tshwm sim ntawm qhov tsis xws luag.
- Cov khoom siv tshuab: Cov qauv ntawm cov pwm yuav tsum muaj zog txaus los tiv thaiv qhov deformation, khoov, thiab sib ntswg los ntawm kev txhaj tshuaj. Tsis tas li ntawd, kev ua haujlwm ntxiv xws li kev rub cov tub ntxhais tseem yuav tsum tau xav txog hauv kev qhib pwm casting. Qhov no yog ib qho tseem ceeb heev rau kev txhim kho qhov zoo ntawm aluminium tuag-casting qhov chaw.
Qhov thib ob, kev tsim cov pwm yuav tsum tau coj mus rau hauv tus account yuav ua li cas kom tsis txhob muaj qhov tsis xws luag, burrs, npuas, pores, thiab lwm yam. Qhov no suav nrog cov khoom siv, qhov loj, thiab cov qauv tsim ntawm cov pwm, uas yuav tsum tau muab cov ncauj lus kom ntxaws thiab kev tshawb fawb ntawm cov txhuas sib txawv. alloy cov ntaub ntawv thiab cov txheej txheem los txiav txim siab cov qauv pwm zoo. Piv txwv li, qhov tsis xws luag tuaj yeem raug txo los ntawm kev ntxiv cov ntaub ntawv muab tub lim, ntxiv cov cua txias, ua kom zoo dua cov rooj vag, thiab lwm yam.
Hauv luv luv, zoo heevaluminium tuag casting manufacturersyuav tsum tau them nyiaj mloog zoo rau cov pwm tsim thiab tsim cov txheej txheem, thiab ib txwm ua tib zoo saib xyuas qhov zoo ntawm aluminium tuag castings. Los ntawm kev siv cov qauv pwm tsim nyog thiab tsim nyog, aluminium alloy tuag casting tuam ntxhab tuaj yeem txhim kho kev tsim khoom thiab tsim cov qauv zoo, yog li ua kom cov neeg siv khoom tuaj yeem tau txais cov khoom zoo tshaj plaws aluminium alloy tuag casting khoom.
