Comprehensive investigation of extrusion of п-shaped brackets. Report 8. Calculation methodology of process parameters during restricted extrusion. Part 2

The continuation 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. The calculation of the limiting cases of asymmetric extrusion is considered, which are reduced, on the one hand, to symmetrical extrusion, and on the other hand, to the complete overlap of the small discharge gap. The mentioned formulas allow us to determine such important parameters of the die forging process as the total and specific deforming forces, as well as the heights of the walls formed as a result of extrusion.
