Enziwa Kanjani Amazinyo Ebhakede Lokusakaza?
Kuthunyelwe nguAdmin
Amazinyo ebhakede le-Cast ayingxenye yemishini ehambisa umhlaba efana nezilayishi kanye nezimbambi.Ngokuvamile zenziwe ngezinto eziqinile futhi ezihlala njalo.Lawa mazinyo avame ukushintshwa ngemva kwesikhathi sokusetshenziswa.Izinto ezisetshenziswa ukwenza la mazinyo zingahluka kuye ngokuthi umshini osetshenzwayo.Amazinyo ebhakede ngokuvamile enziwa nge-alloy material ephansi, enekhabhoni engaphansi kuka-5%.Le alloy inokuqina okuphezulu namandla okukhathala.Ibuye ifanele uhla olubanzi lwezimo zezimayini.Uma kuqhathaniswa namazinyo ebhakede omgunyathi, amazinyo enziwe ngensimbi ashibhile.Kodwa-ke, banokuphila kwesevisi okufushane.Ngakho-ke, kubalulekile ukukhetha amazinyo ebhakede afanele.Amazinyo ebhakede akhiqizwa kusetshenziswa izinqubo ezimbili eziyinhloko zokuphonsa.Lezi zinqubo ziyi-forging kanye nokusakaza okunembayo.I-Forging iyindlela yokwenza izinsimbi ngokufaka ukucindezela okukhulu nezinga lokushisa ensimbi phakathi nenqubo.Phakathi nenqubo yokubumba, ukugeleza okusanhlamvu kwensimbi kulungiselelwa ukunikeza izakhiwo ezithuthukisiwe zemishini.Ukwengeza, amazinyo amabhakede omgunyathi anokumelana nokuguga okuphezulu kanye nempilo ende yesevisi.I-Precision casting iyindlela evame kakhulu ekukhiqizeni amazinyo ebhakede.Inqubo ihilela ukwakheka kokufa, ukwenziwa kwephethini ye-wax, kanye nokuthela.Ngale ndlela, ungakwazi ukulawula isilinganiso sezingxenye ezingagugi.Kodwa, ikhwalithi yomkhiqizo iphansi uma iqhathaniswa nokusakazwa kwesihlabathi.Ukwengeza, izindleko zilinganiselwe.Ukuqamba kuyinqubo emisha yokwenziwa kwamazinyo ebhakede.Ngaphandle kokuthuthukisa ubulukhuni, le nqubo ingasiza ekwandiseni ukuguquguquka kwe-torsional kwamazinyo.Futhi, amazinyo ebhakede akhiwe ahlala isikhathi eside futhi angabizi kakhulu.Njengoba i-cross-section yamazinyo akhiwe iyunifomu, uthola impendulo enhle ekwelapheni ukushisa.Ngaphandle kwalokho, izinyo elibunjiwe lingagoba cishe ngaphambi kokuphuka.Ngaphambi kokubeka i-welding, kubalulekile ukushisa amazinyo ebhakede.Uma kungenjalo, ama-welded seams azoxebuka ngenxa yesimo esibi sokusebenza.Ngaphezu kwalokho, kuthinta ukusebenza kahle kokukhiqizwa kwamazinyo ebhakede angaphezulu.Ungakhuphula i-ductility yamazinyo ebhakede elibunjiwe ngokungeza i-alloy engagugi phakathi nenqubo yokuphonsa.Ukuqinisekisa ikhwalithi yomkhiqizo, ukuphela kwendawo yamazinyo ebhakede kubaluleke kakhulu.Ngaphandle kwalokho, iphethini ye-wax kufanele ibe nokunemba okuphezulu.Futhi, ingakhiqizwa ngama-cores amane.Ngenxa yalokho, ungagcina isikhathi ngokukhiqiza isikhunta kanye kuphela.Isici esiyinhloko se-alloying ekuphonsa amazinyo ebhakede ngu-Mn.Ezinye izakhi ezihlukahlukene zengezwa ekubunjweni.Ngokuvamile, lezi zihlanganisa i-Si ne-carbon.Lapho lezi zakhi zincibilika ndawonye, kwakheka ukugeleza okusanhlamvu okuhle kakhulu.Ngenxa yalokhu, ukunwetshwa kwezinto kukhula kakhulu.Kuye ngohlobo lwamazinyo ebhakede, tInqubo yokukhiqiza ingahlukaniswa ngezigaba ezintathu.Okokuqala, ungacela izinsiza ze-Foundry for the casting.Okulandelayo, ungathola umphakeli womshini nokuhlanganisa.Ekugcineni, ungaqedela amabhakede endaweni yakho.
- NGAPHAMBILI: I-Aluminium Die Casting iyinqubo
- OLANDELAYO: Ungaba kanjani umkhiqizi wekhwalithi ephezulu
