PUNCHING CUPS WITH BOTTOM FLANGE BY DIRECT EXTRUSION WITH COUNTER-PUNCH. DETERMINATION OF THE DEFORMED STATE IN THE FIRST PERIPHERAL REGION OF PLASTIC DEFORMATION
А. Л. Воронцов, I. A. Nikiforov
Abstract
Using the theory of plastic flow according to the method of A. L. Vorontsov, the formulas are obtained that are necessary for calculating the accumulated deformations obtained in the process of extrusion with a counter-punch of the peripheral region adjacent to the formed wall of the product.
