1. Cov txheej txheem ntau lawm ntawm Sand Casting
Sand casting molding cov ntaub ntawv yog pheej yig thiab yooj yim muaj, thiab cov txheej txheem tsim pwm yog yooj yim. Yuav luag tsis muaj kev txwv rau cov hom casting alloys, casting qauv, qhov ntau thiab tsawg, lossis ntau lawm batch. Xuab zeb casting tuaj yeem tsim castings nrog cov duab sab nraud thiab cov kab noj hniav sab hauv, xws li ntau lub thawv, txaj, thav ntawv, thiab lwm yam. Nws tuaj yeem tsim cov castings xws li ob peb grams mus rau ntau pua tons, ua rau nws haum rau ib qho - thooj, batch, thiab ntau lawm. Kev tsim cov xuab zeb casting suav nrog ntau cov kauj ruam, suav nrog molding thiab core- ua, alloy melting, pwm sib dhos thiab nchuav, casting tu, thiab tshuaj xyuas.
2. Xuab zeb Casting txheej txheem tsim cov kauj ruam
Xuab zeb casting txheej txheem tsim yuav tsum yog raws li kev soj ntsuam ntawm cov castability ntawm cov qauv ib feem, ua ke nrog ntau lawm ntim, kev xav tau, thiab ntau lawm tej yam kev mob. Qhov no suav nrog kev xaiv molding thiab cov tub ntxhais- ua txoj hauv kev nrog rau hom pwm, thiab txiav txim siab qhov chaw nchuav thiab qhov chaw sib cais. Cov kauj ruam tshwj xeeb yog raws li nram no:
1) Tshawb xyuas cov duab kos thiab txheeb xyuas cov kev xav tau, cov yam ntxwv ntawm cov qauv, thiab castability ntawm qhov.
2) Tsim cov txheej txheem kev npaj, xaiv molding thiab core- ua txoj hauv kev, txiav txim siab hom pwm, nchuav txoj hauj lwm, ntu ntu, thiab ntsuas los tiv thaiv deformation thiab tawg. Xaiv cov txheej txheem tsis xws li machining nyiaj pub dawb, lub kaum sab xis ntawm lub kaum sab xis, casting shrinkage, thiab tsis yog - nrum qhov thiab grooves. Txiav txim seb tus naj npawb thiab kev npaj ntawm castings hauv cov xuab zeb pwm.
3) Tsim cov xuab zeb cores, txiav txim siab hom, kom muaj nuj nqis, cov qauv ntawm lub taub hau, thiab cov tub ntxhais kev tso kawm ua ntu zus.
4) Tsim lub rooj vag system, risers, chills, feeders, thiab vent qhov.
5) Kos cov txheej txheem kev kos duab thiab cov duab kos (xws li kos duab kos duab thiab pwm sib dhos kos duab).
6) Tsim cov txheej txheem cov cuab yeej, suav nrog cov qauv kos duab, cov duab kos duab kos duab, cov cuab yeej ntsuas tshwj xeeb, thiab cov tub ntxhais kawm sib koom ua ke cov duab kos duab.
7) Npaj cov txheej txheem ua haujlwm tshwj xeeb thiab cov ntaub ntawv thev naus laus zis xws li daim npav txheej txheem casting.
