PUNCHING CUPS WITH BOTTOM FLANGE BY DIRECT EXTRUSION WITH COUNTER-PUNCH. DETERMINATION OF THE DEFORMED STATE DURING CONSTRAINED EXTRUSION IN THE FIRST PERIPHERAL REGION OF PLASTIC DEFORMATION
А. Л. Воронцов, I. A. Nikiforov
Abstract
The formulas necessary for calculating the accumulated deformations obtained in the process of constrained extrusion of the peripheral region adjacent to the matrix are obtained. To derive the formulas, the general method of plastic flow A. L. Vorontsova. The obtained formulas allow us to determine the deformed state of the workpiece at any point in this area. Further, these formulas will be used to take into account the hardening of the extruded material.
