Mbali ndi Ubwino
DIN 6921 ndi mtundu wa bawuti wa hex flange womwe umagwiritsidwa ntchito kwambiri pamafakitale ndi zomangamanga.Bawuti iyi ili ndi flange yomwe imagwira ntchito ngati chochapira chomangidwira ndipo imathandizira kugawa katundu kudera lonse.Mutu wa bolt ndi mawonekedwe a hexagonal ndipo ndi osavuta kumangitsa pogwiritsa ntchito wrench kapena socket.
Bawuti iyi imagwiritsidwa ntchito kwambiri pamakina, m'mafakitale amagalimoto, komanso pomanga, chifukwa cha mphamvu zake zapadera komanso kulimba kwake.Zimapangidwa kuchokera ku zipangizo zamtengo wapatali monga zitsulo zosapanga dzimbiri, titaniyamu, ndi carbon steel, zomwe zimapereka kukana kwa nthawi yaitali kuti zisawonongeke, zowonongeka, ndi dzimbiri.
Maboti a DIN 6921 amapangidwa kuti azitha kulolerana kwambiri ndipo amatsata njira zowongolera kuti atsimikizire kuti akukwaniritsa miyezo yapamwamba kwambiri komanso magwiridwe antchito.Ma bawutiwa amapezeka mosiyanasiyana, kutalika, ndi zomaliza kuti zigwirizane ndi ntchito ndi zofunikira zosiyanasiyana.
Kuphatikiza apo, ma bawuti a DIN 6921 amatsatira miyezo yokhwima yamakampani, kuphatikiza DIN (Deutsches Institut für Normung) ndi miyezo ya ISO (International Organisation for Standardization).Amayesedwanso chifukwa cha kuuma kwawo, kulimba mtima kwawo, komanso kulondola kwake asanatulutsidwe kuti agulitse.Zonsezi zimapangitsa kuti bolt ya DIN 6921 ikhale yabwino kwambiri komanso yodalirika.
Ponseponse, bolt ya DIN 6921 ndi njira yosunthika komanso yolimba yomwe imagwiritsidwa ntchito m'mafakitale osiyanasiyana.Zapangidwa kuti zipereke mphamvu zabwino kwambiri zogwirira, kukana kuvala ndi kung'ambika, komanso kuyika mosavuta.Kumanga kwake kwapamwamba kwambiri komanso kutsatira mosamalitsa miyezo yamakampani kumapangitsa kukhala chisankho chabwino kwambiri kwa mainjiniya, okonza mapulani, ndi akatswiri omanga padziko lonse lapansi.
