Boemo ba mokhatlo oa ho forging ka mor'a ho qhekella

The forging of wheel forgings haholo-holo ho futhumala, deformation le pholiso.Mabili a forging a bonts'a maemo a fapaneng a tlhophiso ka lebaka la sebopeho sa thepa le boholo ba mabili a forging.Ka kakaretso, ho na le haholo-holo lintlha tse peli tse latelang.

1. Boemo ba mokhatlo oa li-forging tse kholo tsa mabili

Mofuta ona oa li-forging tsa mabili hangata o etsoa ka ho qhekella ka ho toba ka li-ingots tsa tšepe.Ka lebaka la palo e phahameng ea ho futhumatsa (mello e 6 kapa ho feta) nakong ea forging, deformation e sa lekanang, phapang e kholo ea likarolo, le tekanyo e phahameng ea motsoako oa thepa, tšobotsi e hlaheletseng ka ho fetisisa ea sebopeho sa li-forgings tse kholo tsa lebili ke lihlahisoa tse phahameng tsa masala a hydrogen. ho se lekane ho hoholo hoa sebopeho.Ho ba teng (phenomenon e tsoakiloeng ea kristale), e leng ntho ea bohlokoa e amang ts'ebetso ea li-forgings tse kholo tsa mabili, kahoo e boetse ke bothata bo lokelang ho rarolloa ka mokhoa oa ho phekola mocheso oa lisebelisoa tse kholo tsa lebili.

2. Boemo ba mokhatlo oa liforomo tsa mabili tse nyane le tse mahareng

Mofuta ona oa liforomo tsa mabili o thehiloe haholo-holo ka ho etsa li-profiles tse rolotsoeng.Bakeng sa litšepe tsa hypoeutectoid (tšepe ea k'habone e mahareng, tšepe e mahareng ea carbon low alloy structural), ka mor'a ho qhekella ho qetela, ha moea o pholile ho isa mocheso oa kamore, ferrite e mahoashe le e kholo le sebopeho sa Lamellar pearlite;bakeng sa litšepe tsa hypereutectoid, haholo-holo litšepe tse nang le k'habone e phahameng le alloy e phahameng, ho pholisa butle ka mor'a ho qhekella ha ho qetela hangata ho ka fumana sebopeho se mahoashe.Ho phaella moo, ka lebaka la phapang ea sebopeho le karolo ea sefapano sa li-forging tsa lebili le pholiso e sa laoleheng, sebopeho hangata ha se lekane.Ka nako e ts'oanang, ka lebaka la litlamorao tsa khatello ea mocheso (hape e bitsoa khatello ea mocheso) le khatello ea sebopeho, khatello e setseng ea ka hare e tla hlahisoa ka har'a mabili, kahoo kalafo ea mocheso e tlameha ho sebelisoa ho li phekola.Ntlafatsa le ho felisa.

Phekolo ea mocheso ea li-forging tsa mabili e ipapisitse le mofuta oa mabili a forging le lisebelisoa tse tala tse sebelisetsoang ho etsa litekanyetso tsa ts'ebetso ea mocheso oa mocheso.Haholo-holo mocheso o futhumatsang, ho tšoara nako le sekhahla sa ho futhumatsa, le ka ho hokahanya ka ho feletseng theknoloji ea ho futhumatsa le thekenoloji ea ho futhumatsa, e leng lisebelisoa tsa ho futhumatsa, lebelo la ho futhumatsa, sepakapaka se futhumatsang le sesebelisoa se pholileng, seaplane se pholileng, ho fumana sebopeho sa metallographic, thepa ea mechine le thepa ea mechine ea forgings ea mabili. .Sebelisa tshebetso.Fana ka ho bapala ka botlalo ho bokhoni ba thepa, 'me u qobe liphoso tsa kalafo ea mocheso (deformation, decarburization, mapetsong le meaho e sa tloaelehang, joalo-joalo), ka hona, kalafo ea mocheso ke mokhoa oa bohlokoa haholo le oa bohlokoahali oa ts'ebetso bakeng sa ho theha liforomo tsa mabili.

Hoo e ka bang liforomo tsohle tse batang, tse futhumetseng le tse chesang tsa mabili li tlameha ho fetisa kalafo ea mocheso hore e be likarolo tse tšoanelehang.Boemo ba theknoloji ea phekolo ea mocheso bo phetha karolo ea bohlokoa ho netefatsa le ho ntlafatsa ts'ebetso, ho nepahala, botsitso le bophelo ba tšebeletso ea likarolo.Ka nako e ts'oanang, lisebelisoa tse tala, ho futhumatsa, The forging process le cooling li boetse li ama boleng ba phekolo ea mocheso oa mabili a forgings.Bobeli bona ba amana haufi-ufi ebile ha ba arohane.
