Ukadaulo wopanga

Kapangidwe ka bar ya mandrel imakhala ndi njira zingapo zovuta komanso zolondola.Choyamba ndi kusungunuka kwa zinthu, zomwe zimatsimikizira kufanana ndi chiyero chapakati pa bar.Kenako kufota, kudzera mukupanga, njere yazinthuzo imayengedwa, potero kuwongolera zinthu zake zamakina ndi moyo wautumiki.The mandrel anamanga amafuna kutentha mankhwala, ndondomeko amachotsa nkhawa mkati ndi kumawonjezera kuuma ndi kuvala kukana kwa mandrel.Kenako, Machining, kuphatikizapo kutembenuka, mphero ndi ntchito zina, kumapangitsa mandrel kukwaniritsa kamangidwe olondola amafuna.Gawo lomaliza ndi chithandizo chapamwamba, monga kuzimitsa, kutentha, etc., kupititsa patsogolo kukana kwa dzimbiri ndi kuuma kwa pamwamba kwa mandrel.

Kuchuluka kwa ntchito ndi mafotokozedwe

Mandrel bar amagwiritsidwa ntchito kwambiri m'mitundu yosiyanasiyana ya mphero, monga MPM (mill-pass rolling mill), PQF (high precision rolling mill) ndi FQM (chigayo chofulumira).Mafotokozedwe ake osiyanasiyana, kuyambira Φ80 mm mpaka 500 mm m'mimba mwake, kutalika kuchokera ku 2500 mm mpaka 17,500 mm, akhoza kukwaniritsa zosowa zosiyanasiyana zopanga.

Kusankha zinthu

Zinthu za bar mandrel zambiri AISI H13 kapena muyezo dziko 4Cr5MoSiV1 ndi 36CrNiMoV6.Zidazi zili ndi zinthu zabwino kwambiri zotentha kwambiri komanso mphamvu zamakina kuti zisunge bata pakutentha komanso kupanikizika kwambiri.Zophatikiza zopanda zitsulo muzinthu za mandrel ziyenera kukhala zosaposa 1.0 giredi A, B, C ndi D, ndipo kukula kwambewu kuyenera kufika giredi 8 kapena kupitilira apo.Zofunikira zakuthupi izi zimatsimikizira kudalirika komanso kudalirika kwa mandrel bar.

Katundu wamakina

Zomwe zimalimbikitsidwa zamakina a mandrel bar a zinthu za H13 ndi izi: Kwa mandrel okhala ndi m'mimba mwake ≤200 mm, mphamvu yamakomedwe ndi 1127-1274 mpa, mphamvu zokolola ndi ≥931MPa, elongation ndi ≥8%, gawo likucheperachepera. ndi ≥25%, ntchito yowonongeka ndi ≥20J, ndipo kuuma ndi HB350-390;Kwa mandrel okhala ndi m'mimba mwake> 200 mm, mphamvu yake yokhazikika ndi 1078-1274 mpa, mphamvu yokolola ndi ≥882MPa, elongation ndi ≥8%, shrinkage ya gawo ndi ≥25%, ntchito yowonongeka ndi ≥20J, kuuma ndi HB330-375.
