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

Mtedza wopanda mutu wa rivetali ndi mitundu iwiri ya ma cylindrical part: yosalala komanso yoyima, pomwe mtedza wa rivet woyimirira umagwiritsidwa ntchito popanga chifukwa cha anti slip effect.Kumapeto kwa nthiti, mutu umalowa m'mbale yopyapyala, ndipo mtedza wa rivet wamtundu wathyathyathya ndiwonso womwe umagwiritsidwa ntchito kwambiri komanso wolimba wa mtedza wa rivet, wokhala ndi nambala yadziko lonse ya GB/17880.1.

Mtedza wa Countersunk rivetnawonso anawagawa mu mitundu iwiri: yosalala ndi ofukula.Amalowetsedwa mu mbale yopyapyala yokhala ndi ma chamfers, ndipo atatha kuyika, mutu wawo umakhala wofanana ndi pamwamba pa mbale yopyapyala.Zida zomwe zilipo zikuphatikizapo: chitsulo, galvanized 304, 316 stainless steel rivet mtedza, ndipo chiwerengero cha dziko ndi GB/T17880.2

Zida za nati yaing'ono ya countersunk rivet ndi chitsulo, 304 chitsulo chosapanga dzimbiri, 3316 chitsulo chosapanga dzimbiri.Nati yaing'ono ya countersunk rivet, motero dzina lake, imatengedwa kuti ili ndi m'mimba mwake yaying'ono ndi makulidwe kuposa mtedza wa countersunk rivet.Ngati pepala chitsulo ndi woonda, chamfer ndi yaing'ono, kapena palibe chamfer, ndi yaing'ono countersunk rivet nati angagwiritsidwe ntchito, ndipo muyezo dziko nambala ndi GB/17880.3.

Zinthu zamtedza wa hexagonal rivetimagawidwanso kukhala chitsulo kanasonkhezereka, 304 zitsulo zosapanga dzimbiri, ndi 316 zitsulo zosapanga dzimbiri, ndipo zomwe zaperekedwa ndi M3-M12.Mtedza wa ma hexagonal rivet nawonso umagawika m'magulu ang'onoang'ono amtundu wa hexagonal rivet mtedza ndi mtedza wawung'ono wamutu wa hexagonal rivet, womwe umayikidwa mu dzenje lapansi la hexagonal.Chifukwa cha mawonekedwe awo a hexagonal, amatha kupewa kutsetsereka ndikupirira torque yayikulu.Pambuyo poyesa, ngakhale ulusi utawonongeka, mtedza wa hexagonal rivet ukhoza kugwedezeka mwamphamvu pa mbale yopyapyala, njira yake yokhazikitsira ndiyofanana ndendende ndi mtedza wamba wozungulira wa rivet, kupatula kuti pobowola pansi, uyenera kukwera. kukhomeredwa mu dzenje lolingana ndi hexagonal, ndi nambala yapadziko lonse ya GB/T17880.5.
