Phekolo ea mocheso ea likarolo tsa forging

Likarolo tse ngata tsa mochini li sebetsa tlas'a meroalo e fapanyetsanang le e amang joalo ka torsion le ho kobeha, 'me bokaholimo ba bona bo na le khatello e matla ho feta ea mantlha; Maemong a khohlano, bokaholimo bo lula bo felile. Ka hona, tlhokahalo ea ho matlafatsa lera la holim'a forgings e behiloe pele, e leng se bolelang hore bokaholimo bo na le matla a phahameng, boima le ho hanyetsa ho apara.

Phekolo ea mocheso oa sefahleho sa forgings karolo ke ts'ebetso e sebetsang feela kalafo ea mocheso holim'a sebaka sa mosebetsi ho fetola sebopeho le thepa ea eona. Hangata, bokaholimo bo na le boima bo phahameng le ho hanyetsa ho roala, ha motheo o ntse o boloka polasetiki e lekaneng le ho tiea. Ha ho etsoa tlhahiso, tšepe e nang le sebopeho se itseng e khethoa pele ho etsa bonnete ba hore thepa ea mochine ea mantlha e finyella litlhoko, ebe mekhoa ea phekolo ea mocheso holim'a metsi e sebelisoa ho matlafatsa lera la holim'a metsi ho finyella litlhoko tsa ts'ebetso. Phekolo ea mocheso oa holim'a metsi e arotsoe ka mekhahlelo e 'meli: ho tima holim'a metsi le phekolo ea mocheso oa lik'hemik'hale.

Ho tima bokaholimo ba likarolo tsa forgings. Ho tima holim'a likarolo tsa forgings ke mokhoa oa phekolo ea mocheso o futhumatsang ka potlako holim'a workpiece ho mocheso oa ho tima, ebe o pholile ka potlako, o lumella feela hore lera la holim'a metsi le fumane sebopeho se tingoeng, ha motheo o ntse o boloka mohaho o tingoang pele. . Tse sebelisoang hangata ke ho tima ka holim'a mocheso oa induction le ho tima lelakabe la ho futhumatsa lelakabe. Ho tima ka holim'a metsi hangata ho sebelisoa bakeng sa tšepe ea khabone e mahareng le litšepe tse mahareng tsa carbon alloy.

Ho tima ho futhumatsa ka induction ho sebelisa molao-motheo oa induction ea motlakase ho kenya maqhubu a maholo a eddy holim'a sebaka sa mosebetsi ka ho feto-fetoha ha motlakase, ho etsa hore bokaholimo ba forging bo futhumale ka potlako ha mantlha e batla e sa futhumale.

Litšobotsi tsa ho tima mocheso oa ho futhumatsa ka induction: ka mor'a ho tima, lithollo tsa martensite lia hloekisoa, 'me boima ba holim'a metsi ke 2-3 HRC e phahameng ho feta ea ho tima e tloaelehileng. Ho na le khatello e kholo ea masala a khatello holim'a lera, e thusang ho ntlafatsa matla a mokhathala; Ha e ratehe ho deformation le oxidative decarburization; Ho bonolo ho fihlella mochini le ho iketsetsa, tse loketseng tlhahiso ea bongata. Kamora ho tima mocheso oa induction, e le ho fokotsa khatello ea maikutlo le brittleness, mocheso o tlase oa mocheso oa 170-200 ℃ oa hlokahala.

Ho tima lelakabe la ho futhumatsa lelakabe ke mokhoa oa ts'ebetso o sebelisang lelakabe la khase ea oksijene ea acetylene (ho fihlela ho 3100-3200 ° C) ho futhumatsa ka potlako holim'a li-forgings ka holim'a mocheso oa phetoho, o lateloa ke ho tima le ho pholile.

Hang-hang tsamaisa mocheso o tlase ka mor'a ho tima, kapa sebelisa mocheso o ka hare oa litšila ho itšehla thajana. Mokhoa ona o ka fumana botebo ba quenching ea 2-6 mm, ka thepa e bonolo le theko e tlaase, e loketseng sehlahisoa se le seng kapa tlhahiso e nyenyane ea batch.
