Mkhalidwe wa bungwe la ma wheel forgings pambuyo popanga

The forging of wheel forgings makamaka amadutsa Kutentha, mapindikidwe ndi kuzirala.Ma wheel forging amawonetsa magawo osiyanasiyana abungwe chifukwa cha kapangidwe kazinthu komanso kukula kwa ma wheel forging.Mwachidule, pali mfundo ziwiri zotsatirazi.

1. Mkhalidwe wa bungwe la ma wheel forgings akulu

Ma wheel forgings amtunduwu nthawi zambiri amapangidwa popanga ma ingots achitsulo.Chifukwa cha kuchuluka kwa kutentha (moto 6 kapena kupitilira apo) pakupangira, kupunduka kosagwirizana, kusiyana kwakukulu kwagawo, komanso kuphatikizika kwazinthu zambiri, gawo lodziwika bwino la kapangidwe ka ma wheel forgings ndi kuchuluka kotsalira kwa haidrojeni, kusagwirizana kwakukulu kwa kapangidwe kake.Kukhalapo (kusakanikirana kwa crystal phenomenon), chomwe ndi chinthu chofunika kwambiri chomwe chimakhudza kugwira ntchito kwa magudumu akuluakulu, choncho ndi vuto lomwe liyenera kuthetsedwa pakupanga ndondomeko ya kutentha kwa magudumu akuluakulu.

2. Mkhalidwe wa bungwe la ma gudumu ang'onoang'ono ndi apakatikati

Mtundu uwu wa ma wheel forgings umapangidwa makamaka ndi kufa kwa mbiri yopindika.Pakuti zitsulo hypoeutectoid (wapakatikati mpweya zitsulo, sing'anga mpweya otsika aloyi structural zitsulo), pambuyo forging komaliza, pamene mpweya utakhazikika kutentha firiji, coarse ndi chachikulu ferrite ndi Lamellar pearlite kapangidwe;kwa zitsulo za hypereutectoid, makamaka zitsulo za carbon ndi high-alloy, kuziziritsa pang'onopang'ono pambuyo popanga komaliza kumatha kupeza kanyumba kolimba kwambiri.Kuonjezera apo, chifukwa cha kusiyana kwa mawonekedwe ndi gawo la mtanda wa magudumu opangira magudumu ndi kuzizira kosalamulirika, mapangidwewo nthawi zambiri amakhala osagwirizana.Nthawi yomweyo, chifukwa cha kupsinjika kwa kutentha (komwe kumatchedwanso kupsinjika kwamafuta) komanso kupsinjika kwamapangidwe, zotsalira zamkati zotsalira zidzapangidwa muzowongolera zamagudumu, chifukwa chake chithandizo cha kutentha chiyenera kugwiritsidwa ntchito pochiza.Konzani ndi kuthetsa.

Kutentha kwa ma wheel forgings kumatengera mtundu wa ma wheel forgings ndi zida zomwe zimagwiritsidwa ntchito popanga magawo opangira kutentha.Makamaka Kutentha kutentha, kugwira nthawi ndi kuzirala mlingo, ndi kudzera mokwanira kugwirizanitsa Kutentha luso ndi kuzirala luso, ndicho zida Kutentha, Kutentha liwiro, Kutentha mlengalenga ndi kuzirala chipangizo, kuzirala sing'anga, kupeza dongosolo metallographic, katundu makina ndi katundu makina a forgings gudumu. .Gwiritsani ntchito.Perekani sewero lathunthu ku kuthekera kwazinthuzo, ndikupewa kuwonongeka kwa chithandizo cha kutentha (mapindikidwe, decarburization, ming'alu ndi zida zachilendo, ndi zina zambiri), kotero chithandizo cha kutentha ndi njira yofunika kwambiri komanso yofunikira kwambiri popanga ma wheel forgings.

Pafupifupi onse ozizira, otentha ndi otentha gudumu forgings ayenera kudutsa kutentha kutentha kukhala mbali oyenerera.Mulingo waukadaulo wochizira kutentha umakhala ndi gawo lalikulu pakuwonetsetsa ndikuwongolera magwiridwe antchito, kulondola, kukhazikika komanso moyo wautumiki wa magawowo.Pa nthawi yomweyo, zipangizo, Kutentha, The forging ndondomeko ndi kuzirala zimakhudzanso kutentha mankhwala khalidwe forgings gudumu.Awiriwa ndi ogwirizana komanso osalekanitsa.
