Xuab zeb casting yog txoj kev casting tshaj plaws. Vim nws tus yam ntxwv (tsis txwv los ntawm cov duab, qhov loj me, complexity thiab alloy hom ntawm qhov chaw, luv luv lub voj voog thiab tus nqi qis), xuab zeb casting tseem yog txoj kev siv ntau tshaj plaws hauv casting ntau lawm. Cov txheej txheem ntawm xuab zeb casting yog raws li nram no:
1. Kev kos duab:
Cov txheej txheem ib txwm yog kom tau txais cov duab kos thiab xa mus rau qhov chaw tsim khoom. Cov txheej txheem no tuaj yeem ua tiav thaum lub sijhawm hais. Niaj hnub no, ntau thiab ntau cov neeg siv khoom thiab cov chaw tsim khoom siv CAD hloov.
2. Pwm:
Pwm yuav tsum tau ua raws li qhov yuav tsum tau kos duab. Feem ntau, cov pwm tuaj yeem siv rau kev tsim khoom ib zaug, cov pwm yas thiab cov pwm hlau tuaj yeem ua rau ntau lawm, thiab cov qauv tuaj yeem ua rau cov khoom loj loj.
3. Sand mixing:
Raws li cov kev xav tau ntawm cov xuab zeb pwm tsim thiab ntau hom castings, tsim nyog molding xuab zeb yuav tsum tau npaj rau molding.
4. Qauv (cov tub ntxhais ua):
Nws muaj xws li molding (ua cov kab noj hniav ntawm cov casting nrog molding xuab zeb), core ua (ua lub puab puab ntawm lub casting), thiab pwm txuam (muab cov tub ntxhais mus rau hauv kab noj hniav thiab kaw lub Upper thiab qis xuab zeb thawv). Moulding yog qhov txuas tseem ceeb hauv casting.
5. Smelting:
Cov tshuaj muaj pes tsawg leeg yuav tsum tau npaj raws li qhov yuav tsum tau muaj hlau muaj pes tsawg leeg, thiab tsim nyog melting rauv yuav tsum raug xaiv los yaj cov ntaub ntawv alloy los tsim cov kua hlau tsim nyog (xws li tsim nyog muaj pes tsawg leeg thiab tsim nyog kub)
6. Pouring:
Ncuav cov khoom tsim nyog molten hlau rau hauv lub thawv xuab zeb uas nruab nrog cov pwm. Theem pouring yog txaus ntshai, yog li yuav tsum tau them tshwj xeeb mloog.
7. Kev ntxuav:
Tom qab pouring thiab cov hlau molten solidifying, tshem tawm cov molding xuab zeb thiab khob tawm ntawm lub rooj vag thiab lwm yam accessories los tsim qhov yuav tsum tau casting.
8. Machining thiab lwm yam kev kho mob:
Raws li cov kev xav tau ntawm cov neeg siv khoom sib txawv, peb tuaj yeem ua cov kev kho cua sov, kev siv tshuab, kev kho deg, thiab lwm yam kev tshuaj xyuas NDT ntxiv.
9. Tshawb xyuas thiab xa khoom
