Aluminium casting inzira yekugadzira kushivirira kwepamusoro uye zvikamu zvemhando yepamusoro nekudira aruminiyamu yakanyungudutswa mune yakanyatsogadzirwa uye nemazvo enjiniya kufa, mold, kana fomu. Iyo inzira inoshanda yekugadzirwa kwezvikamu zvakaoma, zvakaoma, zvakadzama zvinonyatsoenderana nezvinodiwa zvekugadzirwa kwepakutanga.
Iyo Aluminium Casting process
1.Permanent Mold Casting
Yakawanda yekudhura kwealuminium isingaperi mold casting ndiko kugadzira uye kuumbwa kwe mold, iyo inowanzo gadzirwa kubva grey iron kana simbi. Iyo mold inoumbwa muchimiro chejometri chechikamu chakagadzirwa chine zvirevo uye chimiro chechikamu chakakamurwa kuita hafu mbiri. Mukuita jekiseni, hafu ye mold yakavharwa zvakasimba zvekuti hapana mweya kana zvinosvibisa zviripo. Iyo mold inopisa isati yadururwa yealuminium yakanyungudutswa, inogona kuiswa, kudirwa, kana kubaiwa.
Pakupera kwekuita, mold inobvumirwa kutonhora kubvumira chikamu chealuminium kusimba. Kana yatonhodzwa, chikamu chacho chinokurumidza kubviswa kubva mukuumbwa kudzivirira kuumbwa kwekuremara.
Zvisinei nekuti maitiro angaite seakapusa sei, inzira yesainzi uye nehunyanzvi yekugadzira zvikamu zvevhoriyamu yakakwirira.
2.Sand Casting
Kukandwa kwejecha kunosanganisira kurongedza jecha rakatenderedza patani inogona kushandiswa zvakare ine chimiro, ruzivo, uye gadziriso yechigadzirwa chekupedzisira. Inosanganisirwa mupateni inosimuka inobvumira simbi yakanyungudutswa kuti idirwe muforoma uye kuti inopisa aruminiyamu kudyisa kukanda panguva yekusimba kudzivirira shrinkage porosity.
Inosanganisirwa mupateni ndeye sprue inobvumira simbi yakanyungudutswa kuti iiswe mu mold. Zviyero zvepateni zvakakura zvishoma pane chigadzirwa kuverengera shrinkage panguva yekutonhora. Jecha rine huremu uye simba rekuchengetedza chimiro chemuenzaniso uye rinoshingirira kupindirana nesimbi yakanyungudutswa.
4.Vacuum Die Casting Vacuum die casting inoshandisa imba yebhero isina mhepo ine sprue kuvhurika pazasi uye vacuum yekubuda kumusoro. Iyo nzira inotanga nekunyudza sprue pazasi pepamusoro pearuminiyamu yakanyungudutswa. Vacuum inogadzirwa mune inogamuchira ichigadzira mutsauko wepakati pakati pekufa uye iyo yakanyungudutswa aluminium mucrucible.
Musiyano wekumanikidza unokonzeresa kuti aruminiyamu yakanyungudutswa iyerere ichikwidza nesprue mugomba rekufa, uko aluminium yakanyungudutswa inoomesa. Iyo inofa inobviswa kubva kune inogamuchira, yakavhurwa, uye chikamu chinoburitswa.
Kudzora vacuum uye kudzvanywa kusiyanisa pakati pekufa uye yakanyungudutswa aluminium inoita kuti zvikwanise kudzora chiyero chekuzadza chinodiwa nechikamu dhizaini uye gating zvinodiwa. Kudzora kweyero yekuzadza kunowedzera kugona kuona kunzwika kwechikamu chakapedzwa.
Kuita kuti sprue ichinyudzwe pasi pepamusoro pealuminiyamu yakanyungudutswa inova nechokwadi chekuti aruminiyamu yakanyungudutswa ichava alloy yakachena kwazvo isina maokisi uye tsvina. Zvikamu zvakachena uye zvine mutsindo nezvinhu zvishoma zvekune dzimwe nyika.
5.Investment Casting
Investment casting, inozivikanwawo sekukanda wakisi yakarasika, inotanga nekuiswa wakisi mudhi kuti igadzire patani yechigadzirwa chapera. Iwo waxed mapatani anonamirwa kune sprue kugadzira muti ike configuration. Muti unonyikwa muslurry kakawanda, iyo inoumba goko rakasimba receramic rakatenderedza chimiro chewakisi.
Kana iyo ceramic yaiswa uye yakaoma, inopisa mu autoclave kuti ipedze kupera kwe dewax. Kuti uwane tembiricha inodiwa yegomba, inofanopiswa isati yazadzwa nealuminium yakanyungudutswa, inodururwa musprue uye inopfuura nepakati penhevedzano yevamhanyi uye magedhi mune molds. Kana zvikamu zvaoma, ceramic inobviswa ichisiya muti wakabatanidzwa kuti utemwe kubva pamuti.
6.Kurasika Foam Kukanda
Iyo yakarasika yekukanda furo ndiyo imwe mhando yekukandira mari apo wakisi inotsiviwa ne polystyrene foam. Iyo pateni inoumbwa kubva ku polystyrene mugungano resumbu senge mumhanyi uye sprues yekukanda mari. Polystyrene beads anobayiwa mune inopisa aruminiyamu mold pane yakaderera kudzvanywa nemhepo inowedzerwa kuwedzera iyo polystyrene kuzadza makomba.
Iyo pateni inoiswa mujecha rakaoma rakazara rakarongedzerwa iro riine vibration yakasungirirwa kubvisa mavhodhi kana homwe dzemhepo. Sezvo aluminium yakanyungudutswa inodururwa mujecha mold, furo rinopiswa, uye kuumbwa kunoumbwa.
Zvakajairwa Zvishandiso zveKukanda Aluminium
Nekuda kwehunhu hwayo hwakanaka hwemuviri nemakemikari, mazhinji maindasitiri makuru anoshandisa cast aluminium. Heano mashoma akajairika mashandisirwo ezvinyorwa.
1. Indasitiri yezvokurapa
Vagadziri vechikamu chezvokurapa vanovimba nealuminium casts nekuda kwesimba ravo uye huremu mukugadzira prosthetics, mareyi ekuvhiya, etc. Kunze kweizvozvo, nzira yacho yakakodzera kugadzira maumbirwo akaoma uye akarurama ayo indasitiri inozivikanwa nayo. Zvakare, aruminiyamu ndiyo chaiyo zvinhu nekuda kwekuramba kwayo kuita ngura sezvo michina yekurapa yakawanda ichisangana nemvura yemuviri.
2. Indasitiri yemotokari
Vagadziri vezvikamu zvemotokari vanovimba nealuminium casts kune yavo yakareruka zvivakwa pasina kusimba uye kusimba. Nekuda kweizvozvo, yakavandudza kushanda kwemafuta. Uyezve, kugadzira zvikamu zvemotokari zvine maumbirwo akaomarara nearuminiyamu yekukanda maitiro zviri nyore. Aluminium casts akakodzera kugadzira zvikamu zvakaita semabhureki uye mavhiri.
3. Culinary Industry
Cast aluminium inobatsira muindasitiri yezvekubika nekuda kwekugara kwayo, corrosion resistance, lightweight, uye yakanyanya kupisa conduction. Kunze kweizvozvo, zvinhu zvakakodzerwa kugadzira cookware nekuda kwekupisa kwayo kwakanakisa, kureva, inogona kupisa uye kutonhora nekukurumidza.
4. Indasitiri yendege
Aluminium zvikamu zvakakwana kune indasitiri yendege nekuda kwehuremu hwadzo uye simba. Huremu hwayo hunobvumira ndege kushandisa mafuta mashoma kutakura huremu hwakawanda.
