Pali mitundu iwiri ikuluikulu ya zida za crankshaft, imodzi ndichitsulo crankshaftndipo inayo ndi ductilechitsulo crankshaft. Chitsulo chachitsulo chimakhala makamaka chachitsulo chomwe chimatsimikizira mtundu waukulu wa crankshaft. Komanso, luso processing ndi processing kulondola. Crankshaft yachitsulo nthawi zambiri imagwiritsa ntchito njira yozungulira yozungulira. Kulondola kwamakampani a crankshaft sikuwoneka ndi maso. Kuphatikiza pa kugubuduza kozungulira, chitsulo cha ductile iron crankshaft chimafunikanso kukhala ndi nitrided, ndipo mtundu wa crankshaft wa nitrided ndi wakuda. Posankha, samalani kuti musakhale ndi trachoma, kukoka zizindikiro, ndi zina zotero mu gawo la labyrinth, nthawi zambiri sipadzakhala mavuto.

Ukadaulo woponya molakwika:

Kusungunula

Kuti asungunuke chitsulo chosungunuka chapamwamba, ng'anjo yapakatikati yapakatikati idzagwiritsidwa ntchito kusungunula kapena ng'anjo yapakatikati yosinthika, ndipo chowonera molunjika chidzagwiritsidwa ntchito kuti azindikire chitsulo chosungunuka. Nodular cast iron therapy imagwiritsa ntchito subcontracting kuti ipange mitundu yatsopano ya spheroidizing agents, ndipo imagwiritsa ntchito njira zotsogola monga makulitsidwe, incubation, intra-type inoculation ndi pawiri inoculation. Magawo a kusungunuka amayendetsedwa ndi kompyuta ndikuwonetsedwa pazenera.

Kutengera

Kutulutsa thovu kotayika kudzakonzedwa ndikulimbikitsidwa. Poponyera mchenga, jekeseni wopanda mabokosi ndi kuumba kwa extrusion kudzayamikiridwa ndikupitiliza kulimbikitsidwa ndikugwiritsidwa ntchito m'mafakitale atsopano kapena omangidwanso. Mzere wapachiyambi wothamanga kwambiri udzapitirira kugwiritsidwa ntchito, ndipo zina mwazinthu zazikulu zidzasinthidwa kuti zikwaniritse msonkhano wapachiyambi ndi kuchotsa pakati.
