Txoj kev Casting dab tsi muab qhov tseeb tshaj plaws thiab zoo tshaj plaws ntawm Castings?

Thaum nws los txog rau kev ua tiav qhov zoo tshaj plaws thiab zoo tshaj plaws nto ntawm castings, txoj kev casting uas sawv tawm yog peev casting, tseem hu ua poob-wax casting. Cov txheej txheem no muaj kev sib xyaw ua ke ntawm qhov tseeb thiab qhov chaw tiav uas tsis sib xws los ntawm lwm cov txheej txheem casting.

Kev nqis peev casting pib nrog kev tsim cov qauv siv quav ciab, uas yog ib qho kev hloov pauv ntawm qhov xav tau ntawm cov hlau. Cov qauv siv quav ciab yog tom qab ntawd coated nrog cov khoom siv refractory xws li ceramic los tsim lub plhaub tiv thaiv. Lub plhaub no yog hardened thiab siv quav ciab yog yaj, tawm hauv cov pwm hollow uas yog replicates cov duab ntawm tus qauv qub.

Qhov tseeb ntawm cov qauv siv quav ciab yog qhov tseem ceeb hauv kev ua kom tau zoo castings. Niaj hnub nimno CAD / CAM tshuab ua rau kev tsim cov qauv siv quav ciab nrog kev ua haujlwm nruj heev, kom ntseeg tau tias qhov kawg casting yuav zoo sib xws rau cov qauv tsim. Cov ntsiab lus tsis sib xws thiab cov geometry nyuaj uas tuaj yeem ua tiav nrog cov qauv siv quav ciab yog qhov nyuaj lossis tsis tuaj yeem rov ua dua siv lwm txoj hauv kev casting.

Thaum pwm npaj txhij, molten hlau yog poured rau hauv nws. Cov khoom siv refractory tiv taus qhov kub thiab txias ntawm cov hlau molten, tso cai rau nws kom khov rau hauv pwm kab noj hniav. Tom qab ntawd lub plhaub raug tshem tawm, nthuav tawm cov hlau casting. Qhov zoo ntawm qhov casting yog txiav txim siab los ntawm qhov smoothness thiab fineness ntawm pwm lub puab nto.

Peev casting muaj ntau yam zoo uas ua rau nws zoo heev nto zoo. Ua ntej, kev siv cov qauv siv quav ciab thiab cov ntaub ntawv refractory ua rau lub ntsej muag du heev. Cov hlau molten ntws zoo rau hauv pwm, sau txhua yam thiab tsim kom muaj seamless tiav. Qhov thib ob, lub zog centrifugal tsim thaum lub sij hawm nchuav txheej txheem pab faib cov hlau sib npaug hauv cov pwm, ntxiv dag zog rau qhov zoo.

Tsis tas li ntawd, kev nqis peev casting yog cov txheej txheem uas tsis tshua muaj siab, uas txhais tau hais tias muaj qhov tsis sib haum xeeb tsawg thiab muaj kev kub ntxhov uas cuam tshuam txog thaum lub sij hawm casting txheej txheem. Qhov no ua rau kom huv thiab zoo ib yam ntawm qhov chaw tiav.

Lub siab precision thiab nto zoo ntawm peev castings ua rau lawv zoo tagnrho rau ntau yam kev siv. Lawv feem ntau yog siv rau hauv kev lag luam uas xav tau cov khoom zoo, cov khoom sib txawv xws li aerospace, kev kho mob, thiab kev lag luam hniav nyiaj hniav kub. Aerospace Cheebtsam, kev kho mob cog, thiab cov hniav nyiaj hniav kub zoo tsuas yog ob peb yam piv txwv ntawm cov khoom uas tau txais txiaj ntsig los ntawm qhov tseeb thiab du nto tiav los ntawm kev nqis peev casting.

Kev nqis peev casting yog txoj kev casting uas muab qhov tseeb tshaj plaws thiab zoo tshaj plaws nto ntawm castings. Nws lub peev xwm los tsim cov duab zoo nkauj nrog cov npoo du, ua ke nrog kev siv cov cuab yeej siv niaj hnub CAD / CAM thiab cov ntaub ntawv refractory, ua rau cov castings ua tau raws li cov qauv siab tshaj plaws ntawm precision thiab nto zoo. Txawm hais tias nws yog rau cov khoom siv dav hlau tseem ceeb lossis cov hniav nyiaj hniav kub zoo nkauj, kev nqis peev casting tseem yog qhov kev xaiv zoo tshaj plaws rau kev ua tiav cov txiaj ntsig zoo tshaj plaws.
