Mitundu 7 yotentha yoviyitsa mikwingwirima yotsekemera imatha kusinthidwa makonda

Bawuti yooneka ngati 7 ndi mtundu wa bawuti womwe umagwiritsidwa ntchito pomanga, wokhala ndi mawonekedwe a 7. Imatchedwanso kulimbitsa nangula mbale nangula bawuti, welded nangula bawuti, nangula claw nangula bawuti, tendon mbale nangula bawuti, nangula bawuti, nangula wononga, nangula waya, etc. Iwo anakwiriridwa mwapadera mu konkire maziko ndi ntchito ngati maziko kukonza zosiyanasiyana makina ndi zida. Nangula wa mawonekedwe a 7 ndi imodzi mwazitsulo zogwiritsiridwa ntchito kwambiri. Chitsulo cha Q235 nthawi zambiri chimagwiritsidwa ntchito popanga, ndipo zida za Q345B kapena 16Mn zimagwiritsidwa ntchito pokonza mwamphamvu kwambiri, ndipo zida za 40Cr zimagwiritsidwanso ntchito pokonza zinthu zokhala ndi mphamvu ya giredi 8.8, ndipo chitsulo chachiwiri kapena chapamwamba chimagwiritsidwanso ntchito pokonza. Maboti a nangula amagawidwa kukhala ubweya, ndodo zokhuthala ndi ndodo zoonda mosiyanasiyana. Ubweya, ndiye kuti, zitsulo zopangira, zimakonzedwa mwachindunji kuchokera kuzitsulo zozungulira kapena waya popanda kukonzanso. Ndodo yokhuthala imatchedwanso Mtundu A, ndipo ndodo yopyapyala imatchedwanso Mtundu B, zonsezo zimapangidwa ndi chitsulo zitasinthidwa kukhala m'mimba mwake wofunikira. Maboti a nangula amapangidwa powotcherera mbale yachitsulo yolimba yokhala ndi bawuti imodzi yamutu. Kukaniza kwake kotulutsa ndi kolimba. Malinga ndi zikhalidwe zosiyanasiyana zogwiritsiridwa ntchito, amatha kufika ku 3.6, 4.8, 6.8, 8.8, ndi zina zotero. Mphamvu yamagetsi ya grade 3.6 7-bolt nangula bolts ndi mphamvu yamanjenje yachitsulo yokha. Kulimba kwamphamvu kwa mabawuti a nangula okonzedwa mwachindunji ndi Q345B kapena 16Mn zopangira zimatha kufika kumphamvu kwamagiredi 5.8.
