Ukufa kwe-die casting

2021-01-18
1. Kuyini ukulingisa okufa?
Impendulo: Ngesikhathi senqubo yokukhiqiza yokufa, fafaza izinto zohlelo lokuthambisa kanye nezinciphisi odongeni lomgodi, ingaphakathi lomgogodla, isikhunta kanye nezinsimbi zomshini wokufa (ezifana nezilayida, izakhi ze-ejector, izibhakela namakamelo okujova) Ingxube yaziwa kakhulu njengokumbozwa kwensimbi okwenziwe ezweni lami.
2. Uyini umsebenzi wokufa kokulingisa?
Impendulo: (1) Gcina ukusebenza kahle kwe-lubrication emazingeni okushisa aphezulu;
(2) Ukuze ugweme umphumela wokuguguleka kwe-alloy encibilikisiwe ephezulu ebusweni bomgodi, uvimbele isimo sokunamathela kwesikhunta, futhi uthuthukise izimo zokusebenza zemodeli;
(3) Thuthukisa ukuthambekela kwengxubevange ngokunciphisa ukuqhutshwa kokushisa kwemodeli nokugcina uketshezi lwe-alloy encibilikisiwe
(4) Nciphisa ukungqubuzana phakathi kokulingisa kanye nobumba obakha ubuchwepheshe ingxenye yebhizinisi, ngaleyo ndlela kunciphise ukugqokwa komgogodla nomgodi, kunweba impilo yenkonzo yesikhunta nokwenza ngcono ikhwalithi yendawo yokulingisa.
3. Yiziphi izidingo zethu zokumbozwa kokufa?
Impendulo: (1) Iphuzu le-volatilization liphansi, futhi amandla we-dilution enza amandla ngokushesha ku-100 ~ 150â „ƒ.
(2) Ukubhinca okuhle;
(3) Alikho ithonya elonakalisayo kumodeli nasekuphonseni;
(4) Ukuthambisa okuhle;
(5) Ukusebenza okuzinzile;
(6) Akukho phunga elikhethekile, akukho gesi oluyingozi elizonqanyulwa noma libole ekushiseni okuphezulu;
(7) Inqubo elula yokulungiselela;
(8) Ukunikezwa okuchichimayo nentengo ephansi.
4. Yimaphi ama-aluminium alloy die casting die asetshenziswa kakhulu?
Impendulo: (1) uwoyela we-graphite + wenjini, osetshenziselwa ukuthuthukisa ubuchwepheshe bokwakha, enezibhakela eziningi zomjovo namagumbi amaningi okujova;
(2) Ibhitela lika-Oyili, isilinganiso ngu-85/15, ibitume lifudunyezwe libe ngu-80â „ƒ bese liyancibilika, uwoyela uxutshwe ngokulinganayo, okungavimbela ukunamathela kwesikhunta.
