I-CBN Insets vs. Carbide Insert: Ifomula Yezindleko Ezisebenzayo Yomshini Wezinto Eziqinile
I-CBN Insets vs. Carbide Insert: Ifomula Yezindleko Ezisebenzayo Yomshini Wezinto Eziqinile
Ekwenziweni kwesimanjemanje, ukwenziwa kwemishini eqinile kuya ngokuya kuvame, ikakhulukazi ezimbonini ezifana nezezimoto, i-aerospace, kanye namathuluzi, lapho ubulukhuni bezinto zokusebenza ngokuvamile budlula i-HRC50. Ezimweni ezinjalo, ukukhethwa kwamathuluzi kuthinta ngokuqondile ukukhiqiza, ikhwalithi yomshini, kanye nezindleko zizonke. Phakathi kwezinketho ezitholakalayo,I-CBN (Cubic Boron Nitride) ifakafuthiukufakwa kwe-carbideyizixazululo ezimbili ezinkulu.
Lesi sihloko siqhathanisa kokubili kobukhulu obune obuyinhloko—ubulukhuni, ukumelana nokushisa, impilo yamathuluzi, kanye nezindleko-ukucacisa imingcele yohlelo lokusebenza yokufakwa kwe-CBN. Iphinde iveze ucwaningo lwecala lwezindleko zenzuzo kumashini wengxenye yezimoto.
I. Ukuqhathanisa Ukusebenza
1. Ubulukhuni
I-CBN Insets: Okwesibili kuphela kwedayimane ngobulukhuni, ilungele ukukhanda izinsimbi eziqinile ngaphezu kwe-HRC50, i-powder metallurgy, nama-alloys asezingeni eliphezulu.
I-Carbide Insets: Ukuqina cishe kwe-HRA90. Ukugqokwa kwamathuluzi kuyashesha kakhulu uma kwenziwa izinto zokwakha ngaphezu kwe-HRC45.
2. Ukumelana Nokushisa
I-CBN Insets: Imelana namazinga okushisa afika ku-1200°C, ifanele ukusika okomisa ngesivinini esiphezulu, inciphisa ukusetshenziswa kokupholisa.
I-Carbide Insets: Ukumelana nokushisa kufika ku-~800°C; othambekele ekuguqukeni kwepulasitiki nokugqoka kwe-flank ngesivinini esikhulu.
3. Impilo Yamathuluzi
I-CBN Insets: Ingahlala isikhathi eside ngokuphindwe ka-5–10 kune-carbide lapho kwenziwa izinto eziqinile, enikeza ukuzinza okukhulu.
I-Carbide Insets: Impilo yamathuluzi yehla kakhulu ezintweni eziqinile, ezidinga ukushintshwa njalo futhi kubangele isikhathi sokuphumula.
4. Izindleko
I-CBN Insets: Izindleko ezihamba phambili eziphakeme ngokufaka ngakunye, kodwa izindleko ngengxenye ziyehla ngenxa yempilo ende.
I-Carbide Insets: Izindleko zokuqala eziphansi, kodwa ukushintshwa njalo kuphakamisa izindleko zizonke.
II. Imingcele yohlelo lokusebenza yokufakwa kwe-CBN
Ngokusekelwe kulezi zinkomba, izimo ezifanele zokufakwa kwe-CBN zingafingqwa ngokuthi:
Ubulukhuni bezinto ezibonakalayo: HRC50 nangaphezulu, njengezinsimbi eziqinile, i-powder metallurgy, nama-alloys asezingeni eliphezulu.
Usayizi weqoqo lokukhiqiza: Amavolumu aphakathi nendawo ukuya amakhulu, lapho inzuzo yempilo yamathuluzi inciphisa izindleko.
Izidingo zokunemba: Ukubekezelela i-Dimensional IT6 noma okungcono, ukuhwaqeka kwendawo Ra ≤ 0.8 μm.
Indlela yokwenza: Ukusika okomile okunesivinini esikhulu, ukuqeda kancane, noma ukuqeda.
Uma ubulukhuni bempahla buphansi (ngaphansi kwe-HRC45), usayizi webheshi mncane, noma izimfuneko zokunemba zisesilinganisweni, ukufakwa kwe-carbide kuhlala kuwukukhetha okubiza kakhulu.
III. Indaba Yengxenye Yezimoto
Ukuthatha ukuqedwa kokwelashwa kwangemva kokushisa kwamagiya okuhambisa izimoto njengesibonelo:
Okubalulekile: 20CrMnTi, yenziwe lukhuni ku-HRC58–62.
Izidingo zomshini: Ukunemba kwe-Dimensional IT6, ubushelelezi bendawo Ra0.8.
| Into | Faka i-CBN | I-Carbide Insert |
|---|---|---|
| Faka intengo | ~5× ngaphezu kwe-carbide | Isisekelo |
| Impilo yamathuluzi | 6× ubude | 1× (isisekelo) |
| Isikhathi sokuphumula sokushintsha ithuluzi | Phansi | Phezulu |
| Ukusebenza kahle kwemishini | Ukusika okomile okunesivinini esikhulu, +20% ukusebenza kahle | Ukusika ngesivinini esiphansi, ukupholisa kuyadingeka |
| Izindleko ingxenye ngayinye | ~ 15% ngaphansi | Isisekelo |
Umphumela:Ebukhuni obuphezulu, inqwaba enkulu, ukunemba okuphezulu kwegiya machining, nakuba ukufakwa kwe-CBN kubiza kakhulu ucezu ngalunye, ukuphila kwabo okude, izinguquko ezimbalwa zamathuluzi, nokusebenza kahle okuphezulu kunciphisa izindleko zengxenye ngayinye kuyilapho kuqinisekisa ikhwalithi engaguquki kanye namazinga aphansi e-scrap.
IV. Isiphetho kanye Nefomula Yokukhetha Ithuluzi
Okwezinto zokusebenza ezingaphezu kwe-HRC50, ezinembayo nezimfuneko zenqwaba enkulu,Ukufakwa kwe-CBN kuletha isilinganiso esihle kakhulu sokusebenza kwezindleko, kunciphisa kakhulu izindleko zokukhiqiza zizonke kanye nokuthuthukisa ukusebenza kahle. Ngobunzima obuphansi noma imisebenzi ye-batch encane,ukufakwa kwe-carbide kuhlala kusebenza futhi ukonga.
Ifomula Eyenziwe Lula Yokukhetha Ithuluzi:
Uma (Ukuqina Kwezinto ≥ HRC50) KANYE (Usayizi Weqoqo ≥ Medium) KANYE (Precision ≥ IT6)→ KhethaFaka i-CBN
Okunye→ KhethaI-Carbide Insert
Amabhizinisi angasebenzisa le fomula njengereferensi yesinqumo esisheshayo, kuyilapho ecabangela umthamo wemishini, isivinini sokusika, nezimo zokupholisa. Ukusungula imodeli yokuhlaziya yezindleko zenzuzo yokukhethwa kwamathuluzi kuzokhulisa ukusebenza kahle kokukhiqiza kanye nokuncintisana.
