Mabowuti a hexagon kwenikweni amatanthauza zomangira zomwe zimakhala ndi mutu wokhala ndi zomangira.Maboti amagawidwa makamaka kukhala ma bolts achitsulo ndi zitsulo zosapanga dzimbiri malinga ndi zinthu.Iron imagawidwa m'magiredi, ndipo magiredi wamba ndi 4.8, 8.8, ndi 12.9.Chitsulo chosapanga dzimbiri chimapangidwa ndi zitsulo zosapanga dzimbiri SUS201, SUS304, ndi SUS316 mabawuti.
Seti yonse ya mabawuti a hexagon imakhala ndi mutu wa bawuti, nati, ndi gasket yosalala.
Mabowuti a mutu wa hexagon ndi ma bawuti ammutu a hexagonal (ulusi wocheperako) - c ma bawuti ammutu a hexagonal (ulusi wathunthu) - c grade, yomwe imadziwikanso kuti ma hexagonal head bolts (rough) hexagonal head bolts, zomangira zachitsulo zakuda.Miyezo yomwe imagwiritsidwa ntchito kwambiri ndi: sh3404, hg20613, hg20634, ndi zina.
Bolt ya mutu wa hexagon (yofupikitsidwa ngati bawuti ya hexagon) imakhala ndi mutu ndi ndodo ya ulusi (
Magulu onse ogwira ntchito a mabawuti omwe amagwiritsidwa ntchito polumikiza zida zachitsulo amagawidwa m'makalasi opitilira 10, kuphatikiza 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, ndi 12.9.Pakati pawo, mabawuti a giredi 8.8 ndi kupitilira apo, omwe amapangidwa ndi chitsulo chochepa cha carbon alloy kapena sing'anga kaboni chitsulo ndipo amathandizidwa ndi kutentha koyenera (kuzimitsa ndi kutentha), nthawi zambiri amatchedwa mabawuti amphamvu kwambiri, pomwe ena onse amatchulidwa. ngati mabawuti wamba.Chizindikiro cha giredi la bawuti chimakhala ndi magawo awiri a manambala omwe amayimira kuchuluka kwamphamvu kwamphamvu komanso kuchuluka kwa zokolola za bawuti.Chotsatira ndi chitsanzo.
Tanthauzo la ma bolts okhala ndi magwiridwe antchito a 4.6 ndi:
Mphamvu yodziwika bwino ya bolt imafika 400 mpa;
2. Chiŵerengero cha mphamvu zokolola za bawuti ndi 0,6;
3. Mphamvu zotulutsa mwadzina za bawuti mpaka 400 × 0.6 = 240MPa mulingo
Ma bawuti amphamvu kwambiri okhala ndi giredi la 10.9, ndi zinthu zitatha kutentha kumafika:
1. Mphamvu yokhazikika ya bawuti imafika 1000MPa;
2. Chiŵerengero cha mphamvu zokolola za bawuti ndi 0,9;
Mphamvu zokolola mwadzina za bawuti zimafika pamlingo wa 1000 × 0.9 = 900MPa
Tanthauzo la magiredi osiyanasiyana a kagwiridwe ka bawuti ndi muyezo wovomerezeka padziko lonse lapansi.Maboti okhala ndi kalasi yowunika momwe zinthu zimagwirira ntchito amakhala ndi magwiridwe antchito omwewo mosasamala kanthu za zinthu zawo komanso komwe adachokera, ndipo gawo lolozera chitetezo chokha ndi lomwe lingasankhidwe kuti lipangidwe.
