Sanding casting

Sanding casting inoshandiswa kuburitsa akasiyana siyana ezvikamu zvesimbi neakashata majeti. Izvi zvikamu zvinogona kusiyana zvakanyanya muhukuru uye uremu, kubva kumakwenzi emuchato kusvika kune akati wandei matani. Zvimwe zvidiki zvidiki zvejecha zvakakanda zvikamu zvinosanganisira zvikamu sezvakaita magiya, pulleys, crankshafts, kubatanidza tsvimbo, uye propellers. Kukura kwakakura kunosanganisira housings for hombe michina uye zvinorema zvigadziro zvemuchina. Kukanda kwejecha zvakare kwakajairika mukugadzira motokari dzeMotokari, dzakadai seinjhinzi injini, injini mizhinji, misoro yecylinder, uye kutapurirana nyaya.


Sanding Casting, iyo inonyanya kushandiswa kuraswa maitiro, inoshandisa jecha rinoshandisirwa kuumbwa kuumba zvikamu zvesimbi zvakaoma izvo zvinogona kugadzirwa chero upi zvake. Nekuti jecha rakaumbwa rinofanira kuparadzwa kuitira kuti abvise chikamu, anonzi casting, jecha casting kazhinji ane chiyero chakaderera chekugadzira. Iyo jecha yekukanda maitiro inosanganisira kushandiswa kwechoto, simbi, maitiro, uye jecha kuumbwa. Iyo simbi yakanyungudika muvira uye ikabva yadurura uye yakadurura mumusango wejecha rakaumbwa, iro rinoumbwa nemufananidzo. Iyo jecha yakaumbwa inoparadzanisa pamwe chete nemutsara wekuparadzanisa uye kusimbiswa kwekukanda kunogona kubviswa. Matanho ari mune ino maitiro anotsanangurwa zvakadzama muchikamu chinotevera. Mujecha rekukanda, chidimbu chepuraimari chemidziyo chiumbwa, icho chine zvikamu zvakati wandei. Iyo mold yakakamurwa kuita mahafu maviri - iyo yekutsungirira (iyo yepamusoro hafu) uye dhiraivhu (pasi hafu), iyo inosangana nemutsara wekuparadzanisa. Ose mold halves ari mukati mebhokisi, anonzi flask, iyo pachayo yakakamurwa pamwe neiyi mutsara wekuparadzanisa. Iyo Mold Cavity inoumbwa nejecha rakarongedzwa kutenderedza maitiro mune imwe neimwe hafu yeiyo flask. Iro jecha rinogona kunge rakazara neruoko, asi michina idzo dzinoshandisa kumanikidza kana kukanganisa zvine chekuita nejecha uye zvinoda nguva shoma, nekuwedzera huwandu hwekugadzira. Pashure pejecha rave rakarongedzwa uye iyo nzira yabviswa, iyo cavity ichasara iyo inoumba chimiro chekunze chekukanda. Dzimwe nzvimbo dzemukati dzekukanda dzinogona kuumbwa ne cores.


Sanding casting inokwanisa kushandisa chero chero alloy. Kukanda kwejecha kukanda kugona kukanda zvinhu zvine tembiricha dzakakwirira dzekunyungudza, kusanganisira simbi, nickel, uye titanium. Izvo zvinhu zvina zvinowanzoitika zvinoshandiswa mujecha casting zvinoratidzwa pazasi, pamwe chete nekudziya kwavo kwekunyungudutsa

Zvishandiso zvinonyungudutsa tembiricha
Aluminium Alloys 1220 ° F (660 ° C)
Brass Alloys 1980 ° F (1082 ° C)
Cast Iron 1990-2300 ° F (1088-1260 ° C)
Cast Steel 2500 ° F (1371 ° C)

Mutengo wezvezvinyorwa zvejekiseni rekukanda zvinosanganisira mutengo wesimbi, uchinyungudutsa simbi, iyo jecha rinoumba, uye jecha rinorema. Mutengo wesimbi unoremerwa nehuremu hwechikamu, hwakaverengerwa kubva kuChikamu vhoriyamu uye zvekusimudzira kwezvinhu, pamwe nemutengo unit wezvinyorwa. Mari yekunyungudika ichava zvakare yakakura kune yakakura chikamu uremu uye inokurudzirwa nezvinhu, sezvinoita zvimwe zvinhu zvinodhura kuti inyunguduke. Nekudaro, iyo yekunyungudika mutengo mune inowanzove isina kukosha ichienzaniswa nemutengo wesimbi. Iyo huwandu hwejecha rinoumbwa rinoshandiswa, uye nokudaro mutengo, unoenderana nehuremu hwechikamu. Chekupedzisira, mutengo wejecha reCore rinotemerwa nehuwandu uye hukuru hwekirasi dzakashandiswa kukanda chikamu.
