PUNCHING CUPS WITH BOTTOM FLANGE BY DIRECT EXTRUSION WITH COUNTER-PUNCH. DETERMINATION OF THE DEFORMED STATE IN THE FOURTH CENTRAL REGION OF PLASTIC DEFORMATION
Keyword(s):
The formulas necessary for calculating the accumulated deformations obtained in the process of extruding the central region abutting against the working end face of the counter-punch 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.
