Nangula wophatikizidwa ndi mawonekedwe 9 okhala ndi mphamvu yayikulu

Bolt (yachikulu \ yaitali) yogwiritsidwa ntchito kukonza makina akuluakulu ndi zipangizo.Mapeto amodzi a bolt ndi nangula wapansi, womwe umakhazikika pansi (kawirikawiri umatsanulira mu maziko).Ndi zomangira zomangira makina ndi zida.M'mimba mwake nthawi zambiri imakhala mozungulira 20 ~ 45 mm. Poikapo, dulani dzenje losungidwa pazitsulo zachitsulo molunjika pa bawuti ya nangula kumbali kuti mupange poyambira.Mukakwera, kanikizani shimu pansi pa nati (dzenje lapakati likudutsa pa bolt ya nangula) kuti mutseke dzenje lodulidwa ndi poyambira.Ngati bawuti ya nangula ndi yayitali, shimu imatha kukhala yokhuthala.Mukalimbitsa nati, weld shim ndi chitsulo chimango molimba.

Pamene zida zamakina zimayikidwa pamaziko a konkire, malekezero a J-woboola pakati ndi L amakwiriridwa mu konkire kuti agwiritsidwe ntchito.Mphamvu yamphamvu ya bolt ya nangula ndi mphamvu yachitsulo yozungulira yokha, ndipo kukula kwake ndi kofanana ndi malo ozungulira omwe akuchulukitsidwa ndi mtengo wovomerezeka wa kupanikizika (Q235B: 140MPa, 16Mn kapena Q345: 170MPA), yomwe ndi yovomerezeka. mphamvu yamakomedwe pakupanga.Maboti a nangula nthawi zambiri amapangidwa ndi chitsulo cha Q235, chomwe ndi chozungulira.Chitsulo chopangidwa ndi ulusi (Q345) chimakhala ndi mphamvu zambiri, choncho sizovuta kupanga ulusi wa mtedza monga momwe zimakhalira kuzungulira.Kwa mabawuti ozungulira, kuya kokwiriridwa nthawi zambiri kumakhala 25 m'mimba mwake, ndiyeno mbedza ya digirii 90 yokhala ndi kutalika pafupifupi 120mm imapangidwa.Ngati bawutiyo ili ndi mainchesi akulu (mwachitsanzo 45mm) ndipo kuya kwakuya ndikuya kwambiri, mutha kuwotcherera mbale yayikulu kumapeto kwa bawuti, ndiko kuti, kupanga mutu waukulu (koma pali zofunika zina).Kuzama kokwiriridwa ndi mbedza ndikuwonetsetsa kukangana pakati pa bawuti ndi maziko, kuti bawutiyo isakokedwe ndikuwonongeka.
