Li-ring forging ke sehlahisoa sa indasteri ea boqapi le mofuta oa ho qhekella. Ke lintho tse bōpehileng joaloka lesale tse entsoeng ka ho sebelisa matla a ka ntle ho li-billet tsa tšepe (ntle le lipoleiti) le ho li etsa matla a ho hatella a loketseng ka ho fetoha ha polasetiki. Matla ana hangata a finyelloa ka ho sebelisa hamore kapa khatello. Mokhoa oa ho theha o haha mohaho o hloekisitsoeng oa lijo-thollo le ho ntlafatsa thepa ea 'mele ea tšepe. Li-ring forgings li ka bonoa hohle bophelong ba letsatsi le letsatsi mme ke sehlahisoa sa indasteri.
Mokhoa oa tlhahiso
1. Sekoahelo sa terata: Khaola ingot ea tšepe ka boholo bo lekaneng le boima ba 'mele ho latela litlhoko tsa sehlahisoa.
2.Ho futhumatsa (ho kenyeletsoa ho futhumatsa): Thepa ea ho futhumatsa haholo-holo e kenyelletsa sebōpi sa kamore e le 'ngoe, sebōpi sa push rod le sebōpi sa ho futhumatsa tafole. Libōpi tsohle tsa ho futhumatsa li sebelisa khase ea tlhaho e le mafura.
Mocheso oa ho futhumatsa oa ingot ea tšepe hangata ke 1150 ℃～1240 ℃. Nako ea ho futhumatsa ea ingot ea tšepe e batang ke hoo e ka bang lihora tse 1 ho isa ho tse 5, 'me nako ea ho futhumatsa ea ingot ea tšepe e chesang ke halofo ea nako ea ho futhumatsa ea ingot ea tšepe e batang. Ingot ea tšepe e futhumetseng e kena ts'ebetsong ea ho forging.
3. Forging: Ingot ea tšepe e futhumetseng hoo e ka bang 1150～1240℃ e ntšoa ka sebōping sa ho futhumatsa, ebe e kenngoa ka hamore ea moea kapa hamore ea electro-hydraulic ke opareitara. Ho ea ka boholo ba ingot ea tšepe le litlhoko tsa karo-karolelano, ho ts'oaroa ho tšoanang, ho taka le lits'ebetso tse ling li etsoa, boholo ba ho qhekella bo hlahlojoa ka nako ea nnete, 'me mocheso oa forging o laoloa ke thermometer ea infrared.
4. Tlhahlobo: Tlhahlobo ea pele ea sekheo sa forging e etsoa, haholo-holo tlhahlobo ea ponahalo le boholo. Mabapi le ponahalo, tlhahlobo e kholo ke hore na ho na le mefokolo e kang mapetsong. Mabapi le boholo, moeli o se nang letho o tlameha ho tiisetsoa hore o ka har'a litlhoko tsa setšoantšo, 'me litlaleho li tlameha ho bolokoa.
5. Phekolo ea mocheso: Chesa forging ho mocheso o reriloeng esale pele, o boloke o futhumala ka nako e itseng, ebe o o pholile ka lebelo le reriloeng esale pele ho ntlafatsa sebopeho sa ka hare le ts'ebetso ea ho qapa. Sepheo ke ho felisa khatello ea kelello e ka hare, ho thibela deformation nakong ea machining, le ho lokisa ho thatafala ho etsa hore ho be bonolo ho khaola. Ka mor'a phekolo ea mocheso, ingot ea tšepe e pholile moeeng kapa e pholile ka metsi 'me e tima ho latela litlhoko tsa thepa.
6. Ts'ebetso e thata: Ka mor'a hore forging e thehoe ha e le hantle, e sebetsoa hore e be forgings ea litlhaloso tse sa tšoaneng ho latela litlhoko tsa sehlahisoa.
7. Ho lemoha phoso ea Ultrasonic: Ka mor'a hore forging e pholile, mocheso o theohela hoo e ka bang 20 ℃ bakeng sa ho lemoha phoso ea ultrasonic ho finyella litekanyetso tsa naha Ⅰ, Ⅱ, Ⅲ le litekanyetso tse ling le ho hlahloba sekoli holim'a metsi.
8. Teko ea thepa ea mochini: E le ho fihlela litlhoko tsa bareki, thepa ea mochini oa forgings e tlameha ho lekoa, haholo-holo lihlahisoa, matla, tšusumetso le liteko tse ling. Lisebelisoa tse ka sehloohong tsa tlhahlobo tsa k'hamphani li kenyelletsa tlhahlobo e le 'ngoe ea thepa ea bokahohleng, mochini o lekoang o le mong, mochini o le mong oa tšepe o sa khaotseng, 1 ultrasonic flaw detector, 1 magnetic particle flaw detector, 2 thermometers, 1 ea motlakase ea mahare a mabeli, cryostat e le 'ngoe, 1. microscope ea metallographic, 1 metallographic pre-grinder, mochini o le mong oa ho itšeha oa metallographic, 2 Bahlahlobi ba boima ba Brinell, joalo-joalo, ba ka fihlelang litlhoko tsa tlhahlobo ea tloaelo ea liforomo tse fapaneng.
9. Tlhahlobo ea ho qetela: Mekhabiso e phethiloeng e qetella e hlahlojoa ho netefatsa hore ponahalo ea forging e boreleli ebile ha e na mefokolo e kang mapetsong, 'me litekanyo li ka har'a litlhoko tsa litšoantšo 'me li ngotsoe.
10. Ho boloka thepa: Ka mor'a tlhahlobo ea boleng, lithako tse felileng li phutheloa feela ebe li kenngoa ka har'a polokelo ea lihlahisoa tse felileng hore li romeloe.
Mabaka a ts'ebeliso ea li-ring forgings ke: Litšepe tsa diesel ring forging: mofuta oa enjene ea disele. Lienjineri tsa diesel ke mofuta oa mechine e matla, 'me hangata e sebelisoa e le lienjine. Ho nka mohlala oa lienjineri tse kholo tsa diesel, lisebelisoa tse sebelisitsoeng li kenyelletsa lihlooho tsa li-cylinder, likoranta tse kholo, lithupa tse hokelang, lithupa tsa piston, lihlooho tsa piston, li-crosshead pins, likere tsa phetisetso ea crankshaft, mehele ea gear, likere tse mahareng le pompo ea oli. 'mele, joalo-joalo.
Li-ring forgings li na le nalane ea lilemo tse likete naheng ea heso. Ho qhekella ka mochini ho etsoa ho sebelisoa lisebelisoa tsa ho forging lisebelisoa tse fapaneng tsa forging. Mechini ea ho qhekella e ka aroloa ka mekhahlelo e mene ho latela lisebelisoa le lisebelisoa tse sebelisoang: ho forging mahala, ho etsa mohlala, ho forging le ho qhekella ho khethehileng.
Mang kapa mang ea thahasellang lihlahisoa tsa rona, ka kopo ikopanye le rona bakeng sa lethathamo la libuka hodella@welonchina.com. Thankuena!
