Increasing the accuracy during the production of curved metallic billets by bending deformation

Аннотация

The elastoplastic deformation of a billet by bending is considered. The deformation forces are determined and formulas are derived to estimate the accuracy of the curvature of the billet. A bending technology is developed to increase the accuracy of a billet and to decrease the metal losses. The results obtained were used at Tver’ Glass Company to produce curved billets.
