Gear steel round bar ndi mawu wamba achitsulo omwe angagwiritsidwe ntchito pokonza ndi kupanga magiya.Nthawi zambiri, pali zitsulo zotsika mpweya monga 20 # zitsulo, zitsulo zotsika kwambiri za carbon alloy monga 20Cr ndi 20CrMnTi, zitsulo zapakati-mpweya wa carbon monga 35 # zitsulo ndi 45 # zitsulo, ndi zitsulo zapakati-carbon alloy monga 40Cr, 42CrMo. ndi 35CrMo, zomwe zimatha kutchedwa zitsulo zamagiya.
Chitsulo chamtunduwu nthawi zambiri chimakhala ndi mphamvu zabwino, zolimba komanso zolimba pambuyo pa chithandizo cha kutentha malinga ndi zofunikira zogwiritsira ntchito, kapena pamwamba pake sichimva kuvala ndipo pakati pamakhala kulimba kwabwino komanso kukana.
Zofotokozera
1).Zida: 45 #, 16MnCr5, 35SiMn, 40Cr, 40CrNi, 40MnB, 42CrMo, 35CrMo, malinga ndi zomwe kasitomala amafuna
2).Kulongedza: kulongedza koyenera kunyanja
3).Kuchiza pamwamba: kukhomerera, kuwotcherera, utoto kapena monga momwe kasitomala amafunira
4).Kukula: molingana ndi zomwe kasitomala amafuna
Kukula kwa Gear Steel
Gear zitsulo ndi chimodzi mwazinthu zofunika kwambiri zomwe zili ndi zofunikira kwambiri muzitsulo zapadera za alloy zomwe zimagwiritsidwa ntchito pamagalimoto, njanji, zombo ndi makina omanga, komanso ndizomwe zimapangidwira zigawo zikuluzikulu kuti zitsimikizire chitetezo.M'zaka zaposachedwa, zida zitsulo zikukula motsata magwiridwe antchito apamwamba, moyo wautali wautumiki, zida zokhazikika, phokoso lotsika, chitetezo, mtengo wotsika, kukonza kosavuta ndi mitundu yosiyanasiyana.
Gulu la Zida Zachitsulo za Gear
Zida zomwe zimagwiritsidwa ntchito kwambiri pazitsulo zamagiya ndi zitsulo zonyezimira komanso zitsulo zotayidwa.Pakati pawo, zitsulo zotayidwa zimagwiritsidwa ntchito popanga magiya okhala ndi m'mimba mwake kuposa 400mm komanso mawonekedwe ovuta omwe si oyenera kupanga.Nthawi zina, zitsulo zopangidwira zimakhala zoyenera.Chitsulo chopukutira chomwe chimagwiritsidwa ntchito Malingana ndi kuuma kwa dzino kumasiyananso:
1).Zofewa dzino pamwamba
Kulimba kwa dzino pansi pa 350mm kumatchedwa kuti dzino lofewa, chitsulo chomwe chimagwiritsidwa ntchito kwambiri pazitsulo zofewa ndi 45 # zitsulo, 35SiMn, 40Cr, 40CrNi, 40MnB.
2).Kulimba dzino pamwamba
Kuuma kwa dzino pamwamba kuposa 350mm kumatchedwa kulimba kwa dzino.Chitsulo cha zida chomwe chimagwiritsidwa ntchito popanga mano olimba amatha kugawidwa kukhala chitsulo chapakati cha mpweya ndi chitsulo chochepa cha carbon.Sing'anga mpweya zitsulo zikuphatikizapo 35 # zitsulo, 45 # zitsulo,
40Cr, 40CrNi, 42CrMo, 35CrMo, etc. Chitsulo chochepa cha carbon chimaphatikizapo 20Cr, 20CrMnTi, 20MnB, 20CrMnTo, etc.
Kugwiritsa ntchito
1) 42CrMo zida zitsulo zili ndi mawonekedwe amphamvu kwambiri, kuuma kwambiri, kulimba kwabwino, kapindika kakang'ono pakuzimitsa, kulimba kwamphamvu kwambiri komanso kulimba kwamphamvu pakutentha kwambiri.
Amagwiritsidwa ntchito popanga ma forging omwe amafunikira mphamvu zapamwamba komanso zigawo zazikulu zozimitsidwa ndi kutentha kwambiri kuposa zitsulo 35CrMo, monga: magiya akuluakulu oyendetsa galimoto, magiya otumizira ma supercharger, magiya oyendetsa sitima, ma axles akumbuyo, ndodo zolumikizira zodzaza kwambiri ndi akasupe Itha kugwiritsidwanso ntchito mafuta mozama pobowola zitoliro mfundo ndi zida nsomba zosakwana 2000m;ndipo angagwiritsidwe ntchito zisamere nkhungu zamakina opindika, etc.
2) 20CrMnTiH giya chitsulo ndi carburizing chitsulo ndi ntchito bwino, mkulu-kuuma-kulimba, olimba ndi kuvala zosagwira pamwamba pamwamba ndi olimba pakati pambuyo carburizing ndi kuzimitsira, mkulu otsika kutentha mphamvu mphamvu, sing'anga weld-kuthekera, ndipo akhoza welded pambuyo normalizing Good. makina.
Amagwiritsidwa ntchito popanga magawo ofunikira okhala ndi gawo limodzi<30mm yomwe imapirira kuthamanga kwambiri, sing'anga kapena katundu wolemetsa, kukhudzika ndi kukangana;monga: magiya, magiya mphete, zida kutsinde mtanda mitu, etc. Ndi cholowa m'malo zitsulo 18CrMnTi, amene chimagwiritsidwa ntchito ngati mbali carburized.Amagwiritsidwa ntchito m'mafakitale agalimoto ndi mathirakitala omwe ali ndi gawo lochepera 30mm;ndi gawo lofunika kwambiri la carburized lomwe limanyamula katundu wothamanga kwambiri, wapakati kapena wolemetsa ndipo limakhudzidwa ndi kugwedezeka;
