PUNCHING CUPS WITH BOTTOM FLANGE BY DIRECT EXTRUSION WITH COUNTER-PUNCH. DETERMINATION OF KINEMATIC AND STRESS STATES IN THE FOURTH CENTRAL 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 stresses and force parameters of extrusion with the counter-punch of the central region of plastic deformation abutting against the working end face of the counter-punch.
