Ukupholisa kweama-forgingsibhekisela ekupholiseni kusukela ekuzingeleni kokugcina kokushisa kuya ekamelweni lokushisa ngemva kwalokhoukuqamba.Uma indlela yokupholisa ingakhethiwe kahle, i-ama-forgingsingase ichithwe ngenxa yokuqhekeka noma amabala amhlophe, futhi ukukhiqiza kungase kuthinteke ngokunweba umjikelezo wokukhiqiza.Ngakho-ke,ukuqambaukupholisa nakho kuyisixhumanisi esibalulekile kuukuqambaukukhiqizwa.Ukudala ukucindezeleka kwangaphakathi ohlelweni lokupholisa: i-billet izokhiqiza ukucindezeleka kwangaphakathi ohlelweni lokushisa, kanyeukuqambaizophinde ibangele ukucindezeleka kwangaphakathi ohlelweni lokupholisa.Ngoba iama-forgingszisesimweni sokunwebeka nezinga lokushisa eliphansi esikhathini sokupholisa sakamuva, ubungozi bokupholisa ukucindezeleka kwangaphakathi bukhulu kunokushisa kwengcindezi yangaphakathi.Ngokwezimbangela ezihlukahlukene zokucindezeleka kwangaphakathi ngesikhathi sokupholisa, kukhona ukucindezeleka kwezinga lokushisa, ukucindezeleka kwezicubu kanye nokucindezeleka okusele.

1. Ukucindezeleka kwezinga lokushisa esigabeni sokuqala seukuqambaukupholisa, ukupholisa phezulu ngokushesha, ukuncipha kwevolumu enkulu;Ukupholisa kwe-core kuhamba kancane futhi ivolumu iyancipha.Njengoba ukuncipha kobuso buvinjelwa inhliziyo, ukucindezeleka kwezinga lokushisa kukhiqizwa ngaphakathi kwe-forging, ingaphezulu liwukucindezeleka okuqinile, futhi inhliziyo ingcindezi ecindezelayo.Uma iukuqambaimpahla iyinsimbi ethambile enokumelana nokuncane kanye nokuguqulwa kalula, ngokupholisa okuqhubekayo, ingcindezi eqinile ekhiqizwa phezulu ekuqaleni kokupholisa iyancipha kancane kancane ibe ziro ngokukhululeka kokuguqulwa.Esigabeni sakamuva sokupholisa, izinga lokushisa elingaphezulu liphansi kakhulu, futhi ukuncipha kwevolumu kuyama, kuyilapho ukuncipha kwevolumu eyinhloko kuvinjelwe ungqimba olungaphezulu.Ngenxa yalokho, uphawu lokucindezeleka lokushisa luyashintsha, ungqimba olungaphezulu luba ukucindezeleka okucindezelayo, futhi umnyombo uba ukucindezeleka okuqinile.Uma izinto zokwakha zensimbi eziqinile zokumelana nokuguqulwa okukhulu, ekuqaleni kwendawo yokupholisa yokucindezeleka kwe-tensile ayikwazi ukuphumula, sekwephuzile ukupholisa, ukuncipha kwevolumu nakuba ingqikithi enamathiselwe phezu kokucindezeleka kwengcindezi, kodwa futhi ingenza ubuso ekuqaleni kukhiqiza ukucindezeleka okuqinile kuncipha, futhi ngeke kubangele izinguquko ekucindezelweni kwezinga lokushisa kwezimpawu, ubuso namanje ukucindezeleka okuqinile, inhliziyo namanje ukucindezeleka okucindezelayo.Ngakho-ke, ama-forging ensimbi athambile angase abonakale e-crack yangaphakathi lapho epholisa, futhi izinsimbi zensimbi eziqinile kulula ukukhiqiza ukuqhekeka kwangaphandle lapho kupholisa.

2. Ukucindezeleka kwenhlanganoama-forgingskwinqubo yokupholisa, njengokuguqulwa kwesigaba, ngaphezu kokubangela ukucindezeleka kwezinga lokushisa, kuzophinde kukhiqize ukucindezeleka kwenhlangano, futhi kungenxa yokushintshwa kwamandla athile enhlangano ngaphambi nangemva kokuguqulwa kwesigaba, kanye nomphumela wokuguqulwa kwesigaba esihlukile. isikhathi etafuleni lokuqamba.Njengama-forgings enqubweni yokupholisa yokuguqulwa kwe-martensite, ngokushisa kwe-forgings kuncishisiwe, indawo yokuguqulwa kwe-martensite, ngenxa yomthamo othize we-martensite mkhulu kunomthamo othize we-austenite, khona-ke ukucindezeleka kwenhlangano okubangelwa indawo kuyacindezela. ukucindezeleka, inhliziyo icindezelekile.Kodwa ngalesi sikhathi, izinga lokushisa eliyisisekelo liphakeme kakhulu, esimweni esihle se-plastic austenite, ngokusebenzisa ukuguqulwa kwepulasitiki yendawo, ukucindezeleka okungenhla kukhululeka ngokushesha.Khona-ke ukwakhiwa kwaqhubeka kuphole, ukuguqulwa kwe-martensitic kwenzeka enhliziyweni, khona-ke ukucindezeleka kwenhlangano, inhliziyo iyingcindezi ecindezelayo, ungqimba olungaphezulu luyingcindezi eqinile.Ukucindezeleka kuyanda kuze kube yilapho ukuguqulwa kwe-martensite kuqedile.Njengoba umthamo othize wazo zonke izigaba zensimbi mkhulu kune-austenite, ukucindezeleka kwe-microstructure okukhiqizwa ezinye izinguquko ze-microstructure ngesikhathi sokupholisa kokufoja nakho kunomthetho ongenhla.
3.ingcindezi eseleama-forgingsenqubweni yokuqamba, ngenxa yokuguqulwa okungalingani kokucindezeleka kwangaphakathi okubangelwa ukuqina komsebenzi, njengokuphela kungase kube ukuthambisa okufika ngesikhathi kwe-recrystallization ukukuqeda, ngemvaukuqambakuzoba ingcindezi eyinsalela egciniwe.Ukusatshalaliswa kwengcindezi eyinsalela ekubunjweni ngaphakathi kweqembu lesimemezelo ngokuya ngokushintshashintsha okungalingani eqenjini lesimemezelo.Kungaba ingcindezi eqinile endaweni kanye nengcindezi ecindezelayo phakathi nendawo, noma okuphambene nalokho.Kuyabonakala ukuthi kunezinhlobo ezintathu zezingcindezi zangaphakathi ezishiwo ngenhla enqubweni yokupholisa ngemva kwalokhoukuqamba, futhi ingqikithi yokucindezeleka kwangaphakathi ibekwe ngaphezu kokuthathu.Lapho inani lokucindezeleka elibekwe phezulu lidlula umkhawulo wamandla, lizobangela ukuqhekeka ezingxenyeni ezihambisanayo ze-ukuqamba, ukupholisa imifantu kuvame ukwenzeka lapho izinga lokushisa liphansi futhi ipulasitiki impofu:.Okufana ne-superposition yokucindezeleka kwangaphakathi akuzange kubangele umonakalo, ukuphela kokupholisa kuzogcinwa, okubizwa ngokuthi ukucindezeleka okusele kokuqamba.
