Xuab zeb casting yog ib qho txheej txheem casting

Xuab zeb casting yog ib qho txheej txheem casting, tseem hu ua cov xuab zeb casting. Nws yog ib txoj hauv kev ua cov khoom siv los ntawm kev siv xuab zeb hauv cov pwm pov tseg.

Cov xuab zeb casting txheej txheem suav nrog cov kauj ruam hauv qab no:

1. Pwm npaj: ua ob qho pwm nrog qhov zoo thiab tsis zoo concavities raws li cov duab thiab qhov loj me ntawm ib feem. Cov pwm zoo yog hu ua cov tub ntxhais, thiab cov pwm tsis zoo yog hu ua Sandbox. Cov pwm no feem ntau yog ua cov khoom siv refractory.

2. Sand pwm kev npaj: qhov chaw cov tub ntxhais nyob rau hauv lub thawv xuab zeb thiab sau nws nrog foundry xuab zeb ib ncig ntawm cov tub ntxhais. Foundry Sand yog feem ntau yog kev sib xyaw tshwj xeeb ntawm cov xuab zeb zoo, av nplaum thiab dej. Tom qab puv ua tiav, cov xuab zeb pwm tau sib xyaw siv siab siv siab lossis kev co.

3. Melting Hlau: Melting cov hlau uas xav tau rau hauv lub xeev ua kua, feem ntau yog siv lub cub tawg kom sov cov khoom siv hlau. Thaum cov hlau mus txog qhov tsim nyog melting point, cov kauj ruam tom ntej tuaj yeem pib.

4. Pouring: Ua kua hlau yog maj mam nchuav rau hauv cov xuab zeb pwm, txhaws tag nrho cov duab. Cov txheej txheem pouring yuav tsum tau tswj kub thiab nrawm kom tsis txhob muaj npuas, shrinkage kab noj hniav lossis lwm yam tsis xws luag.

5. Solidification thiab cua txias: Thaum cov hlau ua kua hauv lub Casting tau txias thiab ua tau zoo dua li cov pwm tuaj yeem qhib thiab cov khoom sib cais tau muab tshem tawm los ntawm cov xuab zeb pwm.

6. Kev ntxuav thiab tom qab-ua: tshem tawm cov duab kab hlau yuav muaj qee cov xuab zeb lossis grit txuas rau saum npoo thiab yuav tsum tau ntxuav kom huv thiab txiav kom huv. Cov neeg kho tshuab lossis cov qauv siv tshuaj yuav siv tau los tshem tawm grit thiab ua cov kev ntsuas tsim nyog thiab kho.

Xuab zeb casting yog ib qho hloov tau thiab nyiaj txiag ua kom haum rau kev tsim cov hlau seem ntawm ntau qhov ntau thiab tsawg thiab duab. Nws yog dav siv nyob rau hauv kev lag luam xws li automotive, machinery, aerospace thiab lub zog.

Cov txheej txheem xuab zeb casting tuaj yeem yog cov kauj ruam qhia yooj yim raws li cov kauj ruam hauv qab no: melting hlau, pouring, soliding thiab cua txias, tu thiab ua haujlwm.

Xuab zeb casting tuaj yeem faib ua cov hom hauv qab no raws li cov xuab zeb txawv pwm:

1. Sib xyaw xuab zeb casting: Qhov no yog hom xuab zeb uas nquag tshaj plaws. Hauv cov xuab zeb sib xyaw ua ke, ib qho paj xuab toj muaj xuab zeb, binder thiab dej siv. Qhov no xuab zeb pwm muaj lub zog siab thiab lub zog thiab yog qhov tsim nyog rau kev tsim cov me me, nruab nrab thiab loj nrooj.

2. Binder Xuab Zeb Casting: Hom zeb casting siv cov xuab zeb nrog cov phau ntawv tshwj xeeb. Binders txhim kho lub zog thiab kav ntev ntawm xuab zeb pwm thaum tseem txhim kho qhov chaw zoo thiab qhov tseeb ntawm cov khoom siv pov tseg.

3. Nyuaj xuab zeb casting: nyuaj xuab zeb casting siv ib qho nyuaj xuab zeb mould nrog siab tiv thaiv thiab kav ntev. Cov xuab zeb no yog tsim nyog rau kev tsim kom loj thiab siab-thauj khoom ua haujlwm, xws li cov cav thiab cov hauv paus.

4. Xuab zeb casting los ntawm demoulding txoj kev: nyob rau hauv hom zeb casting, cov qauv ntawm cov duab sib txawv yog siv los ua kev npaj thiab pwm noj ntawm cov xuab zeb mould yooj yim. Cov txheej txheem tso cai ntau tshaj suav nrog cov xuab zeb ntsuab, qhuav xuab zeb casting thiab tso cov neeg tus neeg saib xyuas xuab zeb.

5. Txav Model Xuab Zeb Casting: Tsiv QAUV Xuab Zeb Casting yog xuab zeb cam khwb cia uas siv cov pwm txav. Hom qauv no yog tsim nyog rau kev tsim cov cuab yeej ua ke nrog cov qauv nyuaj thiab cov kab tsuag sab hauv, xws li cov zog thiab cov xim tsev.

Qhov saum toj no yog cov txheej txheem dav dav thiab cov kev faib tawm ntawm cov xuab zeb casting. Cov txheej txheem tshwj xeeb thiab kev faib tawm tuaj yeem hloov raws cov kev cai sib txawv sib txawv thiab cov khoom siv.
