Kunezinqubo eziningi ezahlukene ekwakhekeni kwensimbi. Ngokuvamile, ama-billet ensimbi ayashiswa futhi athambekele, okwenza ukucubungula kwensimbi kube lula futhi kuthuthukise izakhiwo zemishini yezingxenye. Ezinye izinqubo futhi zilolonga insimbi ekamelweni lokushisa.
Ake sibheke okuhle nokubi kokugoqeka okushisayo, ukugoqa okubandayo, isihloko esishisayo, nesihloko esibandayo, ngokugxila ekusetshenzisweni kwazo kumabha ensimbi engagqwali, izibophelelo ze-alloy, nezingxenye ezenziwe ngokunemba.
Kuyini i-Hot Rolling?
Ezingeni lokushisa lasekamelweni, insimbi ilukhuni ukuyikhubaza nokuyicubungula. Kodwa-ke, lapho i-billet ishisa futhi ithambile ngaphambi kokugoqa, inqubo iba lula kakhulu-lokhu kubizwa ngokuthi i-hot rolling.I-Hot rolling inezinzuzo eziningana. Okokuqala, amazinga okushisa aphezulu athambisa insimbi, okwenza kube lula ukushintsha ukwakheka kwayo futhi acwengisise okusanhlamvu kwayo, ngaleyo ndlela kuthuthukise izici zayo zokuwumshini. Ukwengeza, ukukhubazeka kwangaphakathi okufana namabhamuza, ukuqhekeka, kanye ne-porosity kungashiselwa ndawonye ngaphansi kwezinga lokushisa eliphezulu nokucindezela. Lokhu kwenzakushisa-igingqiweimigoqo yensimbi engagqwaliilungele izinhlelo zokusebenza zesakhiwo ezidinga ukuqina nokuqina okuthuthukisiwe.Kodwa-ke, ukugoqa okushisayo nakho kunobubi. Ukungcola okugxilwe ekuqaleni ensimbi kungacindezelwa kube yizingqimba ezincane kunokuba kuhlanganiswe nensimbi, okuholela ku-delamination. Ngokuhamba kwesikhathi, lokhu kungabangela ukuqhekeka nokuphuka, okuthinta amandla ensimbi. Ngaphezu kwalokho, phakathi nenqubo yokupholisa ngemva kokugingqika, ukupholisa okungalingani phakathi kwezingqimba zangaphakathi nezingaphandle kungase kubangele ukuguga, amandla okukhathala angenamandla, nezinye izinkinga.
Iyini i-Cold Rolling?
Ukugoqa okubandayo ngokuvamile kubhekisela ekusebenziseni amandla angaphandle ensimbi ekamelweni lokushisa ukuze uyicindezele ibe ugqinsi oluthile. Kodwa-ke, akulungile ukucabanga ukuthi ukugoqa okushisayo kufaka ukufudumeza kuyilapho ukugoqa okubandayo kungakwenzi. Kuye ngempahla, ukugoqa okubandayo kungase kuhlanganise nokufudumeza okuthile. Umehluko oyinhloko ukuthi uma ukucubungula kwenzeka ngaphansi kwezinga lokushisa le-recrystallization, kubhekwa njengokugoqa okubandayo; uma ngenhla, i-hot rolling.Izinzuzo zokugoqa okubandayo zihlanganisa isivinini esikhulu, ukusebenza kahle kokukhiqiza okuphezulu, kanye nekhono lokugcina ubuqotho bokwemboza. Ukugoqa okubandayo kungase futhi kudale izimo ezihlukahlukene ezihlukene ukuze kuhlangatshezwane nezidingo ezihlukene zohlelo lokusebenza futhi kuthuthukise ukuwohloka kwensimbi yepulasitiki. Ingxubevange ebandayoamashidi ensimbinokunembainsimbi engagqwali emapheshanazisetshenziswa kakhulu ezimbonini ze-aerospace, zezimoto, neze-elekthronikhi lapho ukunemba kobukhulu kanye nekhwalithi ephezulu kubaluleke kakhulu.Nokho, ukucindezeleka kwangaphakathi okusalayo kunsimbi egoqelwe ngokubanda kungathinta amandla aphelele noma asendaweni. Ukwengeza, izinto ezigoqiwe ezibandayo zivame ukuba nogqinsi oluncane kanye nomthamo ophansi wokuthwala umthwalo.
Siyini Isihloko Esibandayo?
Isihloko esibandayo, esibuye saziwe ngokuthi ukwakha okubandayo, inqubo lapho insimbi ilolongwa ibe yifomu elithile ngaphakathi kwedayizi ngokusebenzisa amandla omphumela ngaphandle kokushisisa.Isihloko esibandayo sinikeza izinzuzo ezimbalwa. Njengoba i-billet icindezelwe ngokugcwele ku-die, kuncane ukungcola okubonakalayo ngesikhathi sokucubungula. Iphinde inikeze amandla ukukhiqiza okuzenzakalelayo, idla amandla amancane njengoba kungekho ukushisisa okudingekayo, futhi iqeda isidingo senqubo yokupholisa, okwenza ukukhiqiza kusheshe futhi kunciphise izindleko. Lokhu kwenza amakhanda abandayoama-fastenersnjengeamabhawodi ensimbi engagqwali, amantongomane, nama-rivets asebenza kahle kakhulu ekukhiqizeni ngobuningi ngokuchithwa kwezinto ezibonakalayo okuncane.Nokho, eminye imisebenzi yezihloko ezibandayo ayikwazi ukuqedwa ngesinyathelo esisodwa. Esikhundleni salokho, i-workpiece kufanele ikhishwe kancane kancane kuma-dies ahlukene, okudinga izigaba eziningi ukuze kuzuzwe umumo oyifunayo. Ukwengeza, izinto ezisetshenziselwa isihloko ezibandayo azikwazi ukuba nzima kakhulu.
Siyini Isihloko Esishisayo?
Isihloko esishisayo siyinqubo lapho insimbi iqala ukushisisa futhi ithambe, bese ikhubazeka ngokwepulasitiki kusetshenziswa amandla omthelela.Isihloko esishisayo singathuthukisa kakhulu ukwakheka kwangaphakathi kanye nezakhiwo zemishini yensimbi, kuthuthukise amandla ayo kanye nepulasitiki. Futhi kunciphisa ubunzima bokucubungula futhi kwandisa ukusebenza kahle kokukhiqiza. Ama-hot-headed alloy steel fasteners asetshenziswa kakhulu ezinhlelweni ezidinga amandla aphezulu, njenge-aerospace, imishini esindayo, nokwakhiwa.Nokho, isihloko esishisayo sidinga ukutshalwa kwezimali okukhulu kwemishini yokushisisa namandla, okwenza izindleko zokukhiqiza zibe phezulu kakhulu kunesihloko esibandayo.
Ngokuqonda izinzuzo kanye nokulinganiselwa kwalezi zindlela zokwenza insimbi, abakhiqizi bangakhetha indlela efanelekile kakhulu .
