PUNCHING CUPS WITH BOTTOM FLANGE BY DIRECT EXTRUSION WITH COUNTER-PUNCH. DETERMINATION OF KINEMATIC AND STRESS STATES IN THE FIRST PERIPHERAL REGION OF PLASTIC DEFORMATION
А. Л. Воронцов, I. A. Nikiforov
Abstract
Formulas are obtained that relate the current geometric parameters of the extruded blank to the size of the stroke of the punch. Using the theory of plastic flow by the method of A. L. Vorontsov, the formulas are obtained that are necessary for calculating the stresses and force parameters of the extrusion process with the counter-punch of the peripheral region adjacent to the formed wall of the product.
