Kune maviri makuru marudzi e crankshaft zvinhu, imwe ndeyesimbi crankshaftuye imwe yacho i ductileiron crankshaft. Iyo simbi crankshaft inonyanya kuve zvinhu zvesimbi izvo zvinotarisa hukuru hwemhando ye crankshaft. Mukuwedzera, iyo tekinoroji yekugadzira uye kugadzirisa iko kurongeka. Iyo crankshaft yesimbi inowanzo shandisa iyo yakatenderedzwa kutenderedza maitiro. Kurongeka kweindastiri ye crankshaft hakuoneki nemeso. Pamusoro pekutenderera kwekona yekutenderedza maitiro, iyo ductile iron crankshaft inodawo kuve nitrided, uye ruvara rweiyo nitrided crankshaft yakasviba. Paunosarudza, ingoteerera kuti urege kuva netrachoma, kudhonza zviratidzo, nezvimwewo muchikamu chelabyrinth, kazhinji hapazovi nematambudziko.

Yakakasira casting tekinoroji:

Kunyunguduka

Nekunyunguduka kwesimbi yakakandwa yepamusoro-giredhi, hombe-yakakura yepakati frequency choto ichashandiswa kunyunguduka kana frequency kutendeuka yepakati frequency furefu, uye yakananga kuverenga spectrometer ichashandiswa kuona iyo yakanyungudutswa iron kuumbwa. Nodular cast iron treatment inotora subcontracting kugadzira mhando itsva dze spheroidizing agents, uye inotora nzira dzepamusoro dzejekiseni dzakadai se incubation, intra-type inoculation uye compound inoculation. Izvo zviyero zvekunyunguduka zvinodzorwa nekombuta uye zvinoratidzwa pachiratidziri.

Modelling

Kukanda furo kwakarasika kuchagadzirwa nekusimudzirwa. Mukukandira jecha, bhokisi risina jekiseni kuumba uye extrusion molding ichakosheswa uye inoenderera mberi nekusimudzirwa uye kushandiswa mumafekitori matsva kana akavakwazve. Iyo yepakutanga yepamusoro-kumanikidza kuumba mutsara icharamba ichishandiswa, uye zvimwe zvezvinhu zvakakosha zvichagadziriswa kuti zviwane otomatiki core musangano uye kubviswa kwepakati.
