Chifukwa chiyani ma rivets amagwiritsidwa ntchito kwambiri komanso momwe angasankhire zinthu?

Riveting akadali imodzi mwa njira zazikulu zomwe zimagwiritsidwa ntchito pamakampani opanga ndege komanso mafakitale ena opangira kuwala komwe zitsulo zamphamvu kwambiri sizingawotchedwe.Chifukwa cha njira yake yodziyimira payokha.
Zifukwa zazikulu za njira ya riveting ndi izi: mtengo wotsika mtengo, zofunikira zokonzekera dzenje, kudalirika kwakukulu, zolumikizira zamphamvu zomwe zimabweretsedwa ndi kulemera kopepuka ndi kulemera kopepuka, komanso kukana kutopa komwe kumabwera chifukwa cha kutsika kwambiri komanso kulimba kwambiri.
Kodi kusankha zinthu za rivets?Nthawi zambiri, zinthu za kuuma komweko zimasankhidwa molingana ndi momwe zimagwiritsidwira ntchito.Ngati agwiritsidwa ntchito pazitsulo za aluminiyamu, ayenera kusankha ma rivets a aluminium.Ngati imagwiritsidwa ntchito pazitsulo zosapanga dzimbiri, nthawi zambiri zimakhala zofunikira kusankha chitsulo chosapanga dzimbiri champhamvu kwambiri.Pamwamba.

Kukula kwa rivet kungatanthauzenso zomwe zili pansipa.
M'mimba mwake wa rivet ndi osachepera katatu makulidwe a pepala lakuda kwambiri kuti alumikizike.Malinga ndi miyezo yankhondo, kutalika kwa mutu wathyathyathya wa olowa olumikizirana kuyenera kukhala nthawi 1.4 kuposa kukula kwa chitoliro chobowola.Kutalika kuyenera kupitirira nthawi 0,3 kukula kwa chitoliro chobowola.Mutha kugwiritsa ntchito magawo onse otchulidwa kuti muwerengere kutalika kofunikira.Kulekerera nthawi zambiri kumakhala 1.5D.

Mwachitsanzo, riveting mbale ziwiri ndi makulidwe okwana A (mm) pamodzi.M'mimba mwake ya rivet iyenera kukhala 3 xA = 3A (mm).
Chifukwa chake, ma rivets okhala ndi mainchesi pafupi ndi 3A (mm) ayenera kugwiritsidwa ntchito.Kulemera kwachitsulo ndi 2A (mm), 1.5D ndi 4.5A (mm), kotero kutalika kwa rivet kumayenera kukhala 2A + 4.5A = 6.5A (mm).
