Wopanga Bolt Wapamwamba Kwambiri
Zipangizo ndi Miyezo Yoyambira
Zipangizo Zofala: Zipangizo zoyambira zimakhala zachitsulo. Chitsulo chopanda mpweya wambiri (monga Q235) chimagwiritsidwa ntchito pa mabotolo wamba a kalasi 4.8, pomwe chitsulo chapakati cha mpweya (monga chitsulo cha 35# ndi 45#) chimagwiritsidwa ntchito pa mabotolo amphamvu kwambiri. Pa ntchito zapadera, chitsulo chosapanga dzimbiri chotenthetsera chomwe chimaviikidwa mumadzi chimagwiritsidwa ntchito, choyenera malo owononga kwambiri monga malo okhala ndi mankhwala ndi nyanja. Ngakhale kuti mkuwa ungagwiritsidwenso ntchito pa mabotolo a galvanized, mtengo wake wokwera umalepheretsa kugwiritsidwa ntchito pa maulumikizidwe amagetsi.
Miyezo: Mwachitsanzo, mabotolo a hexagonal opangidwa ndi galvanized a grade 8.8 akutsatira miyezo ya dziko ya GB/T5782 (yokhala ndi ulusi wochepa) ndi GB/T5783 (yokhala ndi ulusi wonse). Mafotokozedwe a ulusi amakhudza M1.6 - M20 ndi kupitirira apo, ndi mafotokozedwe omveka bwino a magawo monga pitch ndi kutalika kwa kukula kosiyanasiyana kwa mabotolo.
Zofunika Kuziganizira: Kutentha kwambiri kwa ma galvanizing otenthedwa kungakhudze pang'ono mawonekedwe a makina a ma bolt amphamvu kwambiri a giredi 8.8 ndi kupitirira apo, zomwe zimafuna kuwongolera mwamphamvu magawo a njira panthawi yopanga. Kumbali ina, ma galvanizing ozizira amagwiritsa ntchito njira yotsika kutentha yomwe simasintha mawonekedwe a zinthu zoyambira, zomwe zimapangitsa kuti zikhale zoyenera kwambiri ma bolt olondola kapena zigawo zolondola zomwe zimafuna mphamvu zambiri. Kuphatikiza apo, njira zonse ziwiri zimafuna njira zotetezera chilengedwe: ma galvanizing otenthedwa amafunika kuwongolera kutulutsa kwa utsi wa zinc, pomwe ma galvanizing ozizira amafunika kusamalidwa bwino kwa madzi otayira omwe amapangidwa ndi electroplating.
