Chiyambi Chachidule pa Tungsten Carbide Cold Heading Amwalira

1. Kodi mutu wa tungsten carbide kufa ndi chiyani?

Ndi kuuma kwakukulu komanso mphamvu yopindika kwambiri, mutu wozizira wa tungsten carbide umakanikizidwa ndikuwotchedwa ndi zitsulo za ufa. Amagwiritsidwa ntchito kwambiri pomanga ndi kupanga ma fasteners. Zolemba za mutu wa tungsten carbide zimagwiritsidwa ntchito ngati choyikapo chachikulu chopanikizidwa mu jekete yachitsulo. Kuphatikizidwa ndi jekete lachitsulo, mutu wozizira umafa ndi wosavala komanso wothandiza kwambiri, ndipo moyo wautumiki ukuwonjezeka kwambiri.

2. Mikhalidwe yogwirira ntchito

Pansi pa mphamvu yamphamvu, kupsinjika kwamphamvu kwa nkhonya kumatha kufika kupitirira 2500MPa, pamwamba pa concave kufa ndi malo ogwirira ntchito a nkhonya onse amakumana ndi mikangano yayikulu, ndipo kutentha komwe kumapangidwa pamwamba kumakhala kokwera kwambiri. 300 ℃. Chifukwa cha mawonekedwe osafanana a kumapeto kwa chopanda kanthu, nkhonyayo idzakhalanso ndi nkhawa yopindika. Mutu wozizira umafa chifukwa cha kukhudzidwa kapena kukhudzidwa kwamphamvu kwa magwiridwe antchito osagwira ntchito, kufanana kwawo ndikuti carbide yomangidwa imakhala ndi kulimba kwabwino, kulimba kwa fracture, mphamvu ya kutopa, mphamvu yopindika, komanso kukana kuvala bwino. Choncho zomangira zambiri amapangidwa ndi ozizira mutu amafa.

3. Waukulu kulephera modes

Kuvala kwambiri pamalo ogwirira ntchito a convex ndi concave kufa, kuwonongeka kwa occlusal, kusenda kwa groove yakomweko, kukhumudwitsa kapena kusweka kwa nkhonya, kutupa kapena kusweka kwa kufa, kugwa m'mbali ndi ngodya, ndi zina zambiri.

4. Zofunikira zogwirira ntchito

Kufa kwamutu wozizira kumanyamula katundu wopangidwa ndi mutuwo, ndipo malo ogwirira ntchito akufa amafunikira kukhala olimba kwambiri komanso kukana kuvala, ndipo pachimake chimakhala ndi mphamvu zokwanira komanso zolimba. Ngati gawo lolimba la mutu wozizira lifa ndi lolimba kwambiri kapena lakuya kwambiri, zigawo za nkhungu zidzasweka; m'malo mwake, ntchito pamwamba pa nkhungu zigawo zosavuta kuvala, ndipo zinthu akhakula amamatira ku nkhungu mbali. Kawirikawiri, kuuma kwa nkhonya ndi 60 ~ 62HRC, kufa ndi 58 ~ 60HRC, ndipo kuya kwa wosanjikiza wouma kuyenera kuyendetsedwa ndi 1.5 ~ 4mm. Kufa kwa mutu wozizira kumakhala ndi zolemetsa kwambiri, ndipo pamwamba pa fayiyo imakhala ndi kupsinjika kwakukulu. Zinthu za nkhungu zimafunika kuti zikhale ndi mphamvu zambiri, zolimba, komanso kukana kuvala.

Zhuzhou Better Tungsten Carbide Company yakhala ikupanga tungsten carbide kufa kwa zaka zopitilira 15. Tili ndi masauzande a nkhungu kuti apange mitu yosiyanasiyana ya carbide kufa.
