Kusiyana pakati pa mtedza wa flat head rivet, mtedza wa countersunk head rivet, ndi mtedza wa hexagonal head rivet

Mtedza wa rivet wokhala ndi mutu wathyathyathyaAli ndi mitundu iwiri ya zigawo zozungulira: zosalala ndi zowongoka, pomwe mtedza wowongoka wa rivet umagwiritsidwa ntchito kwambiri popanga zinthu chifukwa cha mphamvu zawo zotsutsana ndi kutsetsereka. Pa gawo lotsatira la riveting, mutu umalowa mu mbale yopyapyala, ndipo mtedza wowongoka wa flat headed rivet ndi womwe umagwiritsidwa ntchito kwambiri komanso wolimba, wokhala ndi nambala ya GB/17880.1.

Mtedza wa rivet wopangidwa ndi countersunkAmagawidwanso m'mitundu iwiri: yosalala ndi yoyimirira. Amalumikizidwa kukhala mbale yopyapyala yokhala ndi ma chamfer, ndipo akayikidwa, mutu wawo umakhala wofanana ndi pamwamba pa mbale yopyapyala. Zipangizo zomwe zilipo ndi monga: chitsulo cholimba, chitsulo chosapanga dzimbiri 304, mtedza wa rivet wa chitsulo chosapanga dzimbiri 316, ndipo nambala ya dziko lonse ndi GB/T17880.2

Zipangizo za nati yaing'ono ya rivet yopangidwa ndi countersunk ndi chitsulo cholimba, chitsulo chosapanga dzimbiri 304, chitsulo chosapanga dzimbiri 3316. Nati yaing'ono ya rivet yopangidwa ndi countersunk, motero dzina lake, imaonedwa kuti ili ndi mainchesi akunja ndi makulidwe ang'onoang'ono kuposa nati ya rivet yopangidwa ndi countersunk. Ngati chitsulocho ndi chopyapyala, chamfer ndi yaying'ono, kapena palibe chamfer, nati yaing'ono ya rivet yopangidwa ndi countersunk yokha ndi yomwe ingagwiritsidwe ntchito, ndipo nambala yake yokhazikika ya dziko lonse ndi GB/17880.3.

Zinthu zamtedza wa hexagonal rivetImagawidwanso m'magawo achitsulo chopangidwa ndi galvanized, chitsulo chosapanga dzimbiri 304, ndi chitsulo chosapanga dzimbiri 316, ndipo zofunikira zomwe zaperekedwa ndi M3-M12. Mtedza wa hexagonal rivet umagawidwanso m'magawo a flat headed hexagonal rivet nuts ndi small headed hexagonal rivet nuts, zomwe zimayikidwa mu dzenje la pansi la hexagonal. Chifukwa cha mawonekedwe awo a hexagonal, zimatha kuletsa kutsetsereka kwathunthu ndikupirira mphamvu yayikulu. Pambuyo poyesa, ngakhale ulusi utawonongeka, mtedza wa hexagonal rivet ukhoza kulumikizidwa mwamphamvu pa mbale yopyapyala. Njira yake yoyikira ndi yofanana ndi ya mtedza wamba wozungulira wa rivet, kupatula kuti pobowola dzenje la pansi, liyenera kubowoledwa mu dzenje la hexagonal lofanana, ndi nambala yadziko lonse ya GB/T17880.5.
