CBN Insets vs. Carbide Insert: Njira Yamtengo Wapatali Yamakina Olimba
CBN Insets vs. Carbide Insert: Njira Yamtengo Wapatali Yamakina Olimba
Pakupanga kwamakono, makina olimba akuchulukirachulukira, makamaka m'mafakitale monga zamagalimoto, zakuthambo, ndi zida, pomwe kulimba kwa zida zogwirira ntchito kumaposa HRC50. Zikatero, kusankha zida kumakhudza kwambiri zokolola, luso la makina, komanso mtengo wake wonse. Mwa njira zomwe zilipo,CBN (Cubic Boron Nitride) amalowetsandizopangira carbidendi njira ziwiri zazikulu.
Nkhaniyi ikufanizira mbali ziwiri zazikuluzikulu zinayi—kuuma, kukana kutentha, moyo wa zida, ndi mtengo-Kufotokozera malire oyenera ogwiritsira ntchito zoyika za CBN. Imaperekanso phunziro la mtengo wopindulitsa pamakina azinthu zamagalimoto.
I. Kufananiza Magwiridwe
1. Kuuma
Zithunzi za CBN: Chachiwiri kwa diamondi mu kuuma, yabwino machining zitsulo zolimba pamwamba HRC50, ufa zitsulo, ndi aloyi kutentha kwambiri.
Zithunzi za Carbide: Kuuma mozungulira HRA90. Kuvala kwa zida kumathamanga kwambiri popanga zida pamwamba pa HRC45.
2. Kukana Kutentha
Zithunzi za CBN: Kupirira kutentha mpaka 1200 ° C, koyenera kudula mothamanga kwambiri, kuchepetsa kugwiritsa ntchito kozizira.
Zithunzi za Carbide: Kukana kutentha mpaka ~ 800 ° C; sachedwa kupindika kwa pulasitiki ndi kuvala m'mbali mothamanga kwambiri.
3. Chida Moyo
Zithunzi za CBN: Itha kukhala nthawi 5-10 kuposa carbide popanga zida zowumitsidwa, zomwe zimapereka kukhazikika kwakukulu.
Zithunzi za Carbide: Moyo wa zida umatsika kwambiri pazida zolimba, zomwe zimafunikira kusinthidwa pafupipafupi ndikupangitsa kutsika.
4. Mtengo
Zithunzi za CBN: Mtengo wam'tsogolo wokwera pamakina aliwonse, koma mtengo pagawo lililonse umatsika chifukwa cha moyo wautali.
Zithunzi za Carbide: Kutsika mtengo koyambira, koma kusintha pafupipafupi kumakweza mtengo wonse.
II. Malire Ogwiritsa Ntchito a CBN Insert
Kutengera zisonyezo izi, zochitika zabwino zoyika CBN zitha kufotokozedwa mwachidule monga:
Kuuma kwakuthupi: HRC50 ndi pamwamba, monga zitsulo zolimba, zitsulo za ufa, ndi ma aloyi otentha kwambiri.
Kukula kwa batch: Ma voliyumu apakati mpaka akulu, pomwe phindu la moyo wa zida limachotsera mtengo wake.
Zofunikira mwatsatanetsatane: Dimensional kulolerana IT6 kapena bwino, pamwamba roughness Ra ≤ 0,8 μm.
Machining njira: Kudula kothamanga kwambiri, kumaliza pang'ono, kapena kumaliza.
Pamene kuuma kwa zinthu kumakhala kotsika (pansi pa HRC45), kukula kwa batch ndi kakang'ono, kapena zofunikira zolondola ndi zapakatikati, zoyikapo za carbide zimakhalabe zosankha zotsika mtengo.
III. Nkhani Yophunzira Yamagalimoto
Kutengera kutsirizitsa kwa magiya otengera magalimoto pambuyo pakutentha kwamoto monga chitsanzo:
Zakuthupi: 20CrMnTi, yowumitsidwa ku HRC58-62.
Zofunikira za makina: Dimensional kulondola IT6, pamwamba roughness Ra0.8.
| Kanthu | Chithunzi cha CBN Insert | Carbide Insert |
|---|---|---|
| Ikani mtengo | ~ 5 × apamwamba kuposa carbide | Zoyambira |
| Chida moyo | 6 × pafupi | 1 × (zoyambira) |
| Nthawi yopuma yosintha chida | Zochepa | Wapamwamba |
| Machining bwino | Kudula kothamanga kwambiri, + 20% kuchita bwino | Kudula kothamanga, koziziritsa kumafunika |
| Mtengo pa gawo | ~ 15% kutsika | Zoyambira |
Zotsatira:Muzovuta kwambiri, zazikuluzikulu, makina oyendetsa bwino kwambiri, ngakhale kuti zoyikapo za CBN ndizokwera mtengo pachidutswa chilichonse, moyo wawo wautali, kusintha kwa zida zochepa, komanso kugwiritsa ntchito bwino kwambiri kumachepetsa mtengo wagawo limodzi ndikuwonetsetsa kukhazikika komanso kutsika kwamitengo yotsika.
IV. Pomaliza ndi Chida Chosankha Fomula
Zogwirira ntchito pamwamba pa HRC50, zolondola kwambiri komanso zofunikira zazikulu,Kuyika kwa CBN kumapereka chiwongolero chabwino kwambiri cha magwiridwe antchito, kuchepetsa kwambiri ndalama zopangira zinthu zonse komanso kukulitsa luso. Kwa kuuma kochepa kapena ntchito zazing'ono,zoyikapo za carbide zimakhalabe zothandiza komanso zachuma.
Chida Chosavuta Chosankhira:
Ngati (Kuuma kwa Zinthu ≥ HRC50) NDI (Batch Kukula ≥ Yapakatikati) NDI (Precision ≥ IT6)→ SankhaniChithunzi cha CBN Insert
Kapena→ SankhaniCarbide Insert
Mabizinesi atha kugwiritsa ntchito fomulayi ngati chiganizo chofulumira, ndikuganiziranso kuchuluka kwa zida, liwiro lodulira, komanso kuzizirira. Kukhazikitsa njira yowunikira phindu lathunthu pakusankha zida kudzakulitsa luso la kupanga komanso kupikisana.
