The report presents calculations for specific deforming forces in П-shaped brackets, highlighting yield stress implications.
The ending of the calculation methodology of the process parameters of the process of restricted extrusion of П-shaped brackets under the conditions of plane deformation in the general case of a nonaligned placement of the punch and the die is stated. In this part of the methodology, the extrusion of a hardening material is considered, for which calculations taking into account hardening are described in detail. The mentioned formulas allow us to determine such important parameters of the forging process as the total and specific deforming forces, the heights of the walls formed as a result of extrusion, as well as an increase in the yield stress.
