Litšobotsi tsa lisebelisoa tsa ho itšeha carbide ke life?
Lisebelisoa tsa carbide, haholo-holo li-indexable carbide, ke lihlahisoa tse ka sehloohong tsa lisebelisoa tsa mochini tsa CNC. Ho tloha lilemong tsa bo-1980, mefuta e fapaneng ea lisebelisoa tsa carbide tse tiileng le tse nang le index, kapa tse kentsoeng, li atolohile libakeng tse fapaneng tsa ts'ebetso. Lisebelisoa, sebelisa li-indexable carbide lisebelisoa ho holisa ho tloha ho lisebelisoa tse bonolo le li-cutter tsa sefahleho ho ea ho lisebelisoa tse nepahetseng, tse rarahaneng le tsa ho etsa. Joale, litšobotsi tsa lisebelisoa tsa carbide ke life?
1. Bothata bo phahameng: Lisebelisoa tse sehang tsa carbide li entsoe ka carbide e thata haholo le ntlha ea ho qhibiliha (e bitsoang hard phase) le metal binder (e bitsoang bonding phase) ka mokhoa oa phofo ea metallurgy, 'me boima ba eona ke 89~93HRA, e phahame haholo ho feta ea tšepe e lebelo le phahameng, ho 5400C, boima bo ntse bo ka fihla ho 82-87HRA, e tšoanang le ea tšepe e phahameng ka mocheso oa kamore (83-86HRA). Ho thatafala ha carbide e entsoeng ka samente ho fapana ho ea ka tlhaho, bongata, boholo ba lijo-thollo le likahare tsa karolo ea tšepe e tlamang, 'me ka kakaretso e fokotseha ka ho eketseha ha likarolo tsa tšepe. Ka likarolo tse tšoanang tsa karolo ea sekhomaretsi, boima ba YT alloy bo phahame ho feta ba YG alloy, ha motsoako o nang le TaC (NbC) o na le boima bo phahameng ka mocheso o phahameng.
2. Matla a ho kobeha le ho tiea: Matla a kobehang a carbide e tloaelehileng ea samente a maemong a 900-1500MPa. Ha litaba tsa karolo e tlamang ea tšepe li phahame, matla a ho kobeha a phahame. Ha litaba tsa binder li tšoana, YG(WC-Co). Matla a alloy a phahame ho feta a alloy ea YT (WC-Tic-Co), 'me matla a fokotseha ka ho eketseha ha litaba tsa TiC. Carbide e entsoeng ka samente ke thepa e brittle, 'me ho tiea ha eona mocheso oa kamore ke 1/30 feela ho 1/8 ea HSS.
3. Ho hanyetsa ho apara hantle. Lebelo la ho itšeha la lisebelisoa tsa carbide tse entsoeng ka samente ke makhetlo a 4 ~ 7 ho feta a tšepe e phahameng, 'me bophelo ba lisebelisoa bo phahame ka makhetlo a 5 ~ 80. Bakeng sa ho etsa liforomo le lisebelisoa tsa ho lekanya, bophelo ba ts'ebeletso bo bolelele ba makhetlo a 20 ho isa ho a 150 ho feta a alloy tool tool. E ka khaola lisebelisoa tse thata tse ka bang 50HRC.
Tšebeliso ea lisebelisoa tsa carbide: lisebelisoa tsa carbide hangata li sebelisoa litsing tsa machining tsa CNC, mechini ea ho betla ea CNC. E ka boela ea kenngoa mochine o tloaelehileng oa ho sila ho sebetsana le lisebelisoa tse batlang li le thata, tse sa rarahanang tsa mocheso.
Hona joale, lisebelisoa tsa ho sebetsa tsa lisebelisoa tse kopantsoeng, lipolasetiki tsa indasteri, lisebelisoa tsa plexiglass le lisebelisoa tsa tšepe tse se nang ferrous 'marakeng kaofela ke lisebelisoa tsa carbide, tse nang le litšobotsi tsa boima bo phahameng, ho hanyetsa ho roala, ho tiea hantle, ho hanyetsa mocheso le ho hanyetsa kutu. Hape le letoto la thepa e babatsehang, haholo-holo boima ba eona bo phahameng le ho hanyetsa ho roala, le haeba e lula e sa fetohe ka mocheso oa 500 ° C, e ntse e e-na le boima bo phahameng ho 1000 ° C.
Carbide e sebelisoa haholo joalo ka lisebelisoa, joalo ka lithulusi tse phetholang, lithulusi tsa ho sila, lipolalara, liboro, lithulusi tse boring, joalo-joalo, bakeng sa ho itšeha tšepe, litšepe tse se nang ferrous, polasetiki, likhoele tsa lik'hemik'hale, graphite, khalase, majoe joalo-joalo. tšepe e ka boela ea sebelisoa bakeng sa ho seha tšepe e sa keneleng mocheso, tšepe e sa jeleng paate, tšepe e phahameng ea manganese, tšepe ea lisebelisoa le lisebelisoa tse ling tse thata ho etsa mochini.
