(1) Carburized mudhudhudhu mapuroti anoda carburized rukoko pane zino pamusoro. Kana iyo "carburized-warm extrusion" maitiro ichishandiswa, kugoverwa kweiyo carburized daro kwakabatana zvakanyanya neiyo deformation nzira yegiya inogadzira. Kune iyo tangential kupatsanurwa extrusion maitiro, iyo carburized dura pamazino egiya rinogovaniswa kubva kune iyo carburized dura pamusoro peiri cylindrical isina chinhu. Mune iyo "carburizing-inodziya extrusion" maitiro egiya, iyo deformation nguva ipfupi, uye kupararira kweiyo carburized dura kunogona kufuratirwa. Zviripachena, mushure mekunge humburumbira hwava giya, iyo nzvimbo yepamusoro inowedzerwa zvakanyanya, uye ukobvu hwenzvimbo yakatakurwa inochinja zvakanyanya. Kana iyo carburized dara iri tangentially yakatsimbirirwa panguva yekuumba maitiro, iyo hukobvu hweiyo carburized dura inowedzera, zvikasadaro, iyo ukobvu inoderera; uye iyo carburized dura Iyo ukobvu shanduko inoenderana neyakawanda tangential deformation. Naizvozvo, kuwanda kwekupararira kweiyo carburized dura kunogona kudzorwa nekudzora iyo tangential deformation yeiyo carburized dura panguva yekudziya extrusion yeiyo giya.

Iko shanduko inofanirwa kunge ichibva kune yakasenderedzwa pamusoro kusvika kune zino mudzi wepasi, uye yekutanga inotora chikamu mukushomeka, iyo yakakura iyo yekuwedzera chiyero, yakatetepa iyo carburized dura; zvinopesana, nekuda kwekufa extrusionKana iko kumanikidza kuchiita chikamu che concave chikamu chekumanikidza chive mudzi wezino, iyo simbi yekumanikidza chikamu chefa pakati pesimbi neiyo radial chikamu chesimbi inova zino crest chikamu, chikamu chesimbi ichi chakamanikidzwa nemaviri ari padyo kufa akapatsanurwa mazino kumusoro, ipapo Ukobvu hwenzvimbo yakatakurwa inowedzera; kana deformation ikawedzera, kana kusangana nemukadzi chakuvhe kuchiiswa kwakakwana kupesana kwechikadzi muforoma, ukobvu hwecarburized rukoko hunogona kudzikiswa kana kutambanuka kuchiitika.
