(1) Ma sprockets amoto wamoto amafunikira wosanjikiza wa carburized pa mano. Pamene njira ya "carburized-warm extrusion" ikugwiritsidwa ntchito, kugawa kwa carburized layer kumagwirizana kwambiri ndi njira yowonongeka yopangira zida. Pakuti tangential kugawanika extrusion ndondomeko, ndi carburized wosanjikiza pa mano zida ndi redistributed kuchokera carburized wosanjikiza pamwamba pa cylindrical akusowekapo. Mu njira ya "carburizing-warm extrusion" ya magiya, nthawi yowonongeka ndi yochepa, ndipo kufalikira kwa carburized layer kumatha kunyalanyazidwa. Mwachiwonekere, pambuyo pa silindayo imakhala giya, malo a pamwamba amawonjezeka kwambiri, ndipo makulidwe a carburized layer amasintha kwambiri. Pamene carburized wosanjikiza ndi tangentially wothinikizidwa pa kupanga ndondomeko, makulidwe a carburized wosanjikiza kuwonjezeka, apo ayi, makulidwe amachepetsa; ndi carburized wosanjikiza Kusintha makulidwe kumadalira kuchuluka kwa tangential deformation. Choncho, makulidwe kagawo ka carburized wosanjikiza amatha kuwongoleredwa ndikuwongolera kupindika kwa tangential kwa wosanjikiza wa carburized panthawi yotentha yamagetsi.
(2) Pamaziko omvetsetsa momwe amapangira mano a njinga yamoto, kukambitsirana kwina pakusintha kuchokera pagawo lopangidwa ndi carburized ya silinda kupita ku carburized wosanjikiza wa giya popanga gawo la zida: silinda yoponderezedwa ndi mano achikazi. wosanjikiza carburized amakhala carburized wosanjikiza wa zida muzu gawo. Kusintha kuyenera kukhala kuchokera pa silinda pamwamba kupita ku mizu ya dzino, ndipo koyambirira kumatenga nawo mbali pakupindika, kukulirakulira kwa kuchuluka, kuonda kwa carburized wosanjikiza; m'malo mwake, chifukwa cha kufa extrusion Pamene kukanikiza kumapangitsa kuti gawo la concave la gawo lopanikizika likhale muzu wa dzino, chitsulo cha gawo lokakamiza la kufa pakati pa chitsulo ndi gawo lozungulira lachitsulo limakhala gawo la dzino. gawo, gawo ili la zitsulo wothinikizidwa ndi awiri moyandikana kufa kugawanika mano pamwamba, ndiye makulidwe a carburized wosanjikiza ukuwonjezeka; pamene mapindikidwe akuwonjezeka, ngati kukhudzana ndi nkhungu yachikazi kumakhudzidwa ndi kukangana kokwanira kwa nkhungu yachikazi, makulidwe a carburized layer amatha kuchepetsedwa pamene kutambasula kumachitika.
