Mapangidwe a Nozzle Holder Body for Common Rail System

1. Ndondomeko Zofotokozera

1.1 Ndikofunikira kugwiritsa ntchito njira yotsekera yotsekeka kuti muwonetsetse kugawa mokhazikika pamtundu wakunja wa gawo lopangidwa.

1.2 The ambiri ndondomeko otaya zikuphatikizapo kudula zinthu, kugawa kulemera, kuwombera kuphulika, chisanadze mafuta, Kutentha, forging, kutentha mankhwala, pamwamba kuyeretsa, maginito tinthu anayendera, etc.

1.3 Kupanga pa siteshoni imodzi ndikwabwino kupanga. 1.4 Zida ziyenera kusankhidwa ku 45 # zitsulo, 20CrMo, 42CrMo zitsulo, ndi zipangizo zina zofanana.

1.5 Ndikoyenera kugwiritsa ntchito makina ocheka kudula zinthu kuchotsa mutu ndi mchira.

1.6 Masamba opindidwa otentha amakondedwa.

1.7 Kuonetsetsa kuti katunduyo wadzazidwa mokwanira ndikuwongolera moyo wakufa, tikulimbikitsidwa kugwiritsa ntchito makina osinthira masitayilo ambiri kuti agawire zinthu zopanda pake ndi mtundu.

1.8 Zinthu zomwe zidasokonekera zimayenera kuomberedwa powombera. Kusankhidwa kwa zida zophulitsira, monga kuwombera koyenera (kuzungulira Φ1.0mm kufika Φ1.5mm), ziyenera kuganizira zinthu monga zofunikira za pamwamba pa mabaluti, kuchuluka kwa zowombera pazungulira, nthawi yowombera, ndi moyo wowombera.

1.9 Kutentha kwa preheating kwa zinthu zolakwika kuyenera kukhala mkati mwa 120 ℃ mpaka 180 ℃.

1.10 Kuyika kwa graphite kusanachitike kuyenera kutsimikiziridwa kutengera mtundu wa graphite, mtundu wapamtunda wa ma forgings, kutentha kwa kutentha, komanso nthawi yayitali.

1.11 Graphite iyenera kutayidwa mofanana pamtunda wa zipangizo zosalongosoka popanda kugwedeza.

1.12 Graphite ayenera kupirira kutentha mozungulira 1000 ℃ ± 40 ℃.

1.13 Ma ng'anjo otenthetsera apakati pafupipafupi amalimbikitsidwa kuti azitenthetsera zida.

1.14 Nthawi yotenthetsera yazinthu zosalongosoka imatha kutsimikizika potengera zida zotenthetsera, kukula kwa billet, ndi liwiro la kupanga, ndicholinga chokwaniritsa kutentha kofananira poyambitsa kuyambitsa.

1.15 Kusankhidwa kwa kutentha kwa kutentha kwa zinthu zosalongosoka kuyenera kuthandizira kupititsa patsogolo kusinthika kwazinthu ndikupeza mawonekedwe abwino a post-forging ndi mawonekedwe apamwamba.

  1. Kupanga

2.1 Kusankhidwa kwa malo olekanitsa a forgings kuyenera kuthandizira kuchotsa nkhungu, kudzaza zitsulo m'bowo, ndikukonza nkhungu.

2.2 Kusanthula kayeseleledwe ka manambala kuyenera kugwiritsidwa ntchito kuwerengera mphamvu ya deformation ndi mphamvu yotsekereza panthawi yopanga.

2.3 The preheating kutentha osiyanasiyana nkhungu zambiri pakati 120 ℃ ndi 250 ℃, ndi osachepera preheating nthawi 30 mphindi. Kutentha kwa nkhungu sikuyenera kupitirira 400 ℃ panthawi yopanga.
