Iqhaza le-Aluminium Heat Treatment ukuthuthukisa izakhiwo zemishini zezinto zokwakha, susa ukucindezelwa okusele futhi uthuthukise imishini yezinsimbi. Ngokwezinhloso ezihlukile zokwelashwa kokushisa, izinqubo zingahlukaniswa ngezigaba ezimbili: ukwelashwa kwe-preheat kanye nokwelashwa kokushisa kokugcina.
Inhloso yokwelashwa kwe-preheat ukuthuthukisa ukusebenza kwenziwa, susa ingcindezi yangaphakathi futhi ulungiselele isakhiwo esihle se-metalligraphic sokwelashwa kokugcina. Inqubo yayo yokwelashwa okushisa ifaka phakathi ukuncibilikisa, okujwayelekile, ukuguga, ukuguga nokucisha nokufutheka nokunye.
1) ukunxusa kanye nokujwayelekile
I-Anneling and Ejwayelekile isetshenziselwa impahla engenalutho eshisayo eshisiwe. I-carbon yensimbi nensimbi ye-alloy enokuqukethwe kwekhabhoni enkulu kune-0.5% kaningi kuvame ukunxuswa ukuze kuncishiswe ubulukhuni babo futhi kube lula ukusika; I-Carbon Steel ne-Alloy Steel ngokuqukethwe kwekhabhoni engaphansi kwe-0,5% kusetshenziselwa ukugwema ukunamathela kumise lapho ubulukhuni buphansi kakhulu. Futhi usebenzise ukwelashwa okujwayelekile. Ukuncishiswa kanye nokwenza izinto ngezinto ezijwayelekile kungahlaziya kabusha okusanhlamvu nokwakheka okufanayo, futhi kulungiselele ukwelashwa okushisayo okulandelayo. I-Anneling and Ejwayelekile ivame ukuhlelwa ngemuva kokuthi kungenalutho kukhiqizwa futhi ngaphambi kwemishini enzima.
2) Ukwelashwa kokuguga
Ukwelashwa kokuguga kusetshenziselwa ikakhulukazi ukuqeda ingcindezi yangaphakathi ekhiqizwe ekukhiqizeni okungenalutho kanye nemishini.
Ukuze ugweme umthwalo wezethuli wezokuhamba, wezingxenye ngokunemba okujwayelekile, kwanele ukuhlela ukwelashwa okukodwa ngaphambi kokuqeda. Kodwa-ke, izingxenye ezinezidingo eziphezulu eziqondile, njengebhokisi lomshini we-jig boring, njll., Kufanele kuhlelwe izinqubo zokwelashwa ezimbili noma ezimbalwa noma ezimbalwa. Izingxenye ezilula ngokuvamile azidingi ukwelashwa kokuguga.
Ngaphezu kwezinkambo, ngezingxenye ezithile ezinokunembile ngokuqina okuqinile, okufana nesikulufu sokunemba, ukuze kuqedwe izingcindezi zangaphakathi ezikhiqizwe ngesikhathi sokucubungula futhi zisebenze ngokunemba kwezingxenye, ukwelashwa okuningi kokuguga kuvame ukuhlelwa phakathi kwemishini enzima nokuqeda imishini ye-semi. Kwezinye izingxenye shaft, ukwelashwa kokuguga kufanele futhi kuhlelwe ngemuva kwenqubo eqondile.
3) ukucimana nokugunda
ukucimana nokugunda kubhekisele ekulweni okuphezulu kokushisa ngemuva kokucima. Ingathola umfaniswano nesakhiwo se-sorbite enomsuka, okuwukuhlelwa kokunciphisa ukonakala ngesikhathi sokwelashwa komhlaba kanye nokwelashwa kwe-nitriting. Ngakho-ke, ukucimana nokugunda nokugunda nakho kungasetjenziswa njengokwelashwa kwe-Preheat.
Ngenxa yezakhiwo ezingcono zemishini eziphelele zezingxenye ezicijile nezinomoya omnandi, futhi zingasetshenziswa njengenqubo yokugcina yokwelashwa kwezingxenye ezithile ezingadingi ukuqina okuphezulu nokugqoka.
Inhloso yokwelashwa kokugcina kokushisa ukuthuthukisa izakhiwo zemishini ezifana nobulukhuni, gqoka ukumelana namandla. Inqubo yayo yokwelashwa kokushisa ifaka ukujula, ukucubungula izicubu kanye nokucishwa, kanye nokwelashwa okuhle.
1) ukucima
Ukuqedwa kuhlukaniswe ububanzi bendawo bese uqala ukujula. Phakathi kwazo, ukujuluka kwendawo kusetshenziswa kabanzi ngenxa yoguquko lwayo oluncane, i-oxidation kanye nokukhiqizwa kwe-decormarburlisazation, futhi ukujuluka kwe-surven nakho kunezinzuzo zamandla amakhulu angaphandle kanye nokumelana kahle nokuphikiswa okuhle. Ukuze uthuthukise izakhiwo zemishini zezingxenye ezicijile ingaphezulu, ukwelashwa kokushisa njengokucimana nokusula noma okujwayelekile kuvame ukudingeka njengokwelashwa okushisa kwangaphambi kokushisa. Indlela yayo evamile yenqubo yilena: Ukukhishwa, okudala, okujwayelekile, ukunxusa, imishini evuthayo, ukuqeda nokulangazelela, ukuqeda ukuqeda, ukuqeda.
2) ukucwazimula nokucisha
I-Carburshing kanye nokugunda ukwandisa okuqukethwe kwekhabhoni kwesendlalelo sengxenye yokuqala, futhi ngemuva kokucima, ungqimba olungaphezulu uthola lukhuni oluphezulu, ngenkathi ingxenye ebalulekile igcina amandla athile nokuqina kweplastiki. I-Carburbizing ihlukaniswe izicubu jikelele kanye nokuzikhandla okuyingxenye. Lapho kwenziwa ingxenye ethile ye-carburing, izindlela zokulwa namakhasi kufanele zithathwe izingxenye ezingezona ze-carburshing. Njengoba ukucwazimula nokucimana kwabangela ukonakala okukhulu, futhi ukujula kwe-carbuling ngokuvamile kuphakathi kuka-0,5 no-2 mm, inqubo yokukhalisa ngokuvamile ihlelwe phakathi kokuqeda ukuqeda ukuqeda nokuqeda.
Umzila wenqubo ngokuvamile: Ukungena, ubize, ngokwejwayelekile, imishini evuthayo, ukuqeda ama-semivini, ukuqeda, ukuqeda ukuqeda, ukuqeda. Lapho ingxenye engabingelwanga ye-carburing futhi icijile ingxenye yamukele uhlelo lwenqubo yokususa ungqimba olubiwe ngokwedlulele ngemuva kokukhulisa umugqa, inqubo yokususa ungqimba olwenziwe ngokweqile kufanele ihlelwe ngemuva kokuzikhandla.
3) Ukwelashwa okuhle
I-Nitriding yinqubo yokungena ngaphakathi kwama-athomu ama-nitrogen angena endaweni yensimbi ukuthola ungqimba lwamakhompiyutha aqukethe ama-nitrogen. Ungqimba lwe-nitriding lungathuthukisa ubulukhuni, gqoka ukumelana, amandla okukhathala kanye nokuphikiswa kokugqwala kobuso bengxenye. Njengoba izinga lokushisa lokwelashwa le-nitriding liphansi, ukuguquguquka kunciphile, futhi ungqimba lwe-nitriding mncane, ngokuvamile alukho ngaphezu kwe-0.6 ~ 0.6 ~ 0.6mm, inqubo ye-nitriding kufanele ihlelwe ngasekupheleni kwesikhathi. Ukuze unciphise ukuguquguquka ngesikhathi sokuphumula, ngokuvamile kuthatha ukushisa okuphezulu kokukhululeka kwengcindezi.
