Calculated and Analytical Method of Inertia Forces in Conditions of Drawing Stripe in the Monolithic Wedge Portage

I.V. Dobrov

Abstract


On the basis of the universal energy method for solving technological problems of metal forming developed the methods and obtained formulas for calculating power parameters of high-speed drawing process of the stripe in the monolithic portage, considering the characteristics of the inertia force in the plastically deformable workpiece in comparison with the inertia forces in the mechanical systems of rigid bodies. These differences are due primarily to the fact that when you move the workpiece material in the deformation zone with variable acceleration is a change in the specific gravity of the workpiece along the length of the deformation zone and the power of the inertia forces deformable workpiece is the total differential of the current value of the inertia force to a variable speed of change of these force in the length of the deformation zone.
