Inkqubo yokuvelisa amavili emoto ye-aluminium alloy yahlulwe ikakhulu kwezi ndidi zilandelayo:
1. Inkqubo yokuphosa:
• Ukubunjwa komxhuzulane: Galela ingxubevange yealuminiyam elulwelo kwisingundo, gcwalisa ukungunda phantsi komxhuzulane kwaye uyipholise imile. Le nkqubo inotyalo-mali oluphantsi lwezixhobo kunye nokusebenza okulula, okufanelekile kwimveliso encinci. Nangona kunjalo, ukusebenza kakuhle kokuphosa kuphantsi, ukuguquguquka komgangatho wemveliso kubi, kwaye iziphene zokuphosa ezinje ngeepores kunye nokuncipha ziqhele ukwenzeka.
• I-low-pressure casting: Kwi-crucible evaliweyo, ulwelo lwe-aluminiyam ye-alloy lucinezelwa kwi-mold ngoxinzelelo oluphantsi ngegesi engasebenziyo ukuyiqinisa phantsi koxinzelelo. I-castings eveliswa yile nkqubo inesakhiwo esixineneyo, umgangatho olungileyo wangaphakathi, ukusebenza kakuhle kwemveliso ephezulu, kwaye ifanelekile kwimveliso yobuninzi, kodwa utyalo-mali lwezixhobo lukhulu, iimfuno zokubumba ziphezulu, kunye neendleko zokubumba nazo ziphezulu.
• I-Spin casting: Yinkqubo ephuculweyo esekelwe kuxinzelelo oluphantsi. Okokuqala, i-blank yevili yenziwa ngokuphosa uxinzelelo oluphantsi, kwaye ke i-blank igxininiswe kumatshini ojikelezayo. Ulwakhiwo lwenxalenye yerim ngokuthe ngcembe lukhubazeka kwaye lwandiswe ngumbumba ojikelezayo kunye noxinzelelo. Le nkqubo ayigcini nje kuphela izibonelelo zokuphoswa koxinzelelo oluphantsi, kodwa iphucula amandla kunye nokuchaneka kwevili, ngelixa ikwanciphisa ubunzima bevili.
2. Inkqubo yokuqulunqa
Emva kokuba i-alloy ye-aluminiyam ifudunyezwe kwiqondo elithile lobushushu, ibunjwa ibe ngumbumba ngomatshini wokushicilela. Iinkqubo zokwenziwa zinokwahlulwa ngokwezi ntlobo zimbini zilandelayo:
• Ukubunjwa okuqhelekileyo: Iqhekeza lonke le-ingot ye-aluminiyam yenziwe ngokuthe ngqo kwimilo yevili phantsi koxinzelelo oluphezulu. Ivili eliveliswe yile nkqubo linosetyenziso oluphezulu lwemathiriyeli, inkunkuma encinci, iipropathi ezigqwesileyo zoomatshini bokubumba, kunye namandla amahle kunye nokuqina. Nangona kunjalo, utyalo-mali lwezixhobo lukhulu, inkqubo inzima, kwaye inqanaba lobugcisa bomqhubi lifuneka ukuba libe phezulu.
• I-Semi-solid forging: Okokuqala, i-alloy ye-aluminiyam ifudunyezwa ide ibe semi-solid, ngelo xesha ialloyi ye-aluminiyam inolwelo oluthile kunye nokuqikelelwa, ize emva koko yenziwe. Le nkqubo inokunciphisa ukusetyenziswa kwamandla kwinkqubo yokubumba, ukuphucula ukusebenza kakuhle kwemveliso, kunye nokuphucula umgangatho wevili.
3. Inkqubo ye-welding
Iphepha liqengqeleke libe yisilinda kwaye lidityaniswe, kwaye licutshungulwa nje okanye licinezelwe kwirim yevili ngokungunda, kwaye ke idiski yevili yangaphambili idityaniswe ukuvelisa ivili. Indlela ye-welding ingaba ye-laser welding, i-electron beam welding, njl.
