The formulas necessary for calculating the accumulated deformations obtained during extrusion with a counter-punch of the central region adjacent to the formed wall of the product are obtained. To derive the formulas, we used the general method of plastic flow of A. L. Vorontsov. 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.
