Vipengele na Faida
Flange Bolt Din 6921 Cl 8.8 ni kifaa cha kufunga chenye nguvu ya juu ambacho hutumiwa sana katika utumizi mzito.Ni aina ya bolt ya flange ambayo imeundwa na flange inayofanana na washer kwenye msingi, ambayo hutoa usaidizi wa ziada na kuzuia bolt kulegea kwa sababu ya mtetemo au torque.Bolt ina kichwa cha hexagon ambacho huruhusu usakinishaji na kuondolewa kwa urahisi kwa kutumia wrench au koleo.
Imetengenezwa kwa kufuata kiwango cha DIN 6921, bolt hii ya flange inakidhi mahitaji maalum ya saizi ya uzi, urefu, na lami, pamoja na nyenzo na sifa za kiufundi.Imetengenezwa kwa chuma cha kati cha kaboni kilichounganishwa na vipengele kama vile chromium, molybdenum na vanadium, ambayo huongeza nguvu na uimara wake.Bolt pia imepakwa safu ya kinga, kama vile uwekaji wa zinki au mabati, ambayo huzuia kutu na kutengeneza kutu.
Boliti hii ya flange ina daraja la 8.8, inayoonyesha nguvu yake ya mkazo ya angalau 800 N/mm2 na nguvu ya mavuno ya angalau 640 N/mm2.Hii huifanya kufaa kwa matumizi katika programu zinazohitaji nguvu ya juu ya kubana na upinzani dhidi ya uchovu, athari na nguvu za kando.Inatumika sana katika matumizi ya magari, ujenzi, mashine na vifaa vya viwandani.
Urefu wa bolt hutofautiana kulingana na mahitaji maalum ya maombi, kuanzia 10 mm hadi 100 mm au zaidi.Ukubwa wa nyuzi ni kati ya M6 hadi M30 au zaidi, na aina tofauti za lami zinapatikana kama vile laini, mbavu na nyembamba zaidi.Kichwa cha heksagoni kinaweza kuwa na mikunjo au chembechembe na pia kinaweza kuwa na mapumziko au alama ya kuonyesha mtengenezaji au daraja.
Kwa ujumla, Flange Bolt Din 6921 Cl 8.8 ni suluhisho la kuaminika na la kudumu la kufunga ambalo hutoa nguvu bora, utulivu, na upinzani wa kutu.Muundo wake wa ubora wa juu na utengenezaji wa usahihi huhakikisha utendakazi na usalama bora katika matumizi mbalimbali ya kazi nzito.
