Ungakhetha kanjani umshini wokucubungula isikhunta?
Kunezinhlobo eziningi zesikhunta, izimo zokusebenza zesikhunta ezihlukahlukene zihluke kakhulu, futhi amafomu okuhluleka nawo ahlukile.
Ukucubungula isikhunta kunezici eziyisikhombisa eziyisisekelo ezilandelayo:
(1) Ukunemba kokucubungula kuphezulu, ipheya yesikhunta ngokuvamile yakhiwe nge-concave die, i-convex die kanye nesisekelo sesikhunta, okunye kungase kube imojula yomhlangano wezingcezu eziningi.Ngakho-ke, inhlanganisela yokufa okuphezulu nangaphansi, inhlanganisela yokufaka ne-cavity, kanye nenhlanganisela phakathi kwamamojula konke kudinga ukunemba okuphezulu kwemishini.Ukunemba kobukhulu bedayizi kuvame ukufika kusigaba esingu-μ M.
(2) Ukuma nobuso beminye imikhiqizo, njengamaphaneli ezimoto, izingxenye zendiza, amathoyizi nezinto zasendlini, kuyinkimbinkimbi.Ingaphezulu lomumo lakhiwe izinhlobonhlobo zezindawo ezigobile.Ngakho-ke, i-cavity surface yesikhunta iyinkimbinkimbi kakhulu.Ezinye izindawo ziphathwa ngezibalo.
(3) Ukukhiqizwa kwesikhunta esincane se-batch akukona ukukhiqizwa okukhulu, ezimweni eziningi, kukhiqizwa inqwaba eyodwa kuphela.
(4) Ziningi izinqubo zokusebenza, ezifana nokugaya, ukubhora, ukubhoboza, ukuphinda futhi ucofe.
(5) Impilo yesevisi yesikhunta sokukhiqiza esiphindaphindayo yinde.Lapho impilo yesevisi yesikhunta idlula impilo yayo, kuyadingeka ukufaka esikhundleni sesikhunta esisha, ngakho-ke ukukhiqizwa kwesikhunta kuvame ukuphindaphinda.
(6) Ekukhiqizeni isikhunta senqubo yokukopisha, ngezinye izikhathi akukho mdwebo noma idatha, futhi inqubo yokukopisha kufanele yenziwe ngokuvumelana nento yangempela.Lokhu kudinga ukunemba okuphezulu kokulingisa futhi akukho deformation.
(7) Impahla yokudayila yinhle kakhulu futhi ubulukhuni buphezulu.Izinto eziyinhloko ze-die yinsimbi ye-alloy, ikakhulukazi i-die enempilo ende yenziwe nge-Crl2, i-CrWMn nenye insimbi ye-ledeburite.Lolu hlobo lwensimbi lunezidingo eziqinile kusukela ekubunjweni okungenalutho, ukucubungula kuya ekushiseni.Ngakho-ke, ukusungulwa kobuchwepheshe bokucubungula akunakunakwa, futhi ukuguqulwa kokwelashwa kokushisa nakho kuyinkinga enkulu ekucubunguleni.
Ukuze kunwetshwe impilo yesevisi yefa, ukukhethwa kwamathuluzi omshini kufanele kuhlangabezane nezidingo zokucubungula ngangokunokwenzeka ngokuya ngezimo zokusebenza kanye namafomu okuhluleka kwefa.Isibonelo, umsebenzi wesistimu yokulawula izinombolo kufanele ube namandla, ukunemba kwethuluzi lomshini kufanele kube phezulu, ukuqina kuhle, ukuzinza kwe-thermal kuhle, nomsebenzi wokukopisha kufanele unikezwe.
