Research of stamping of unequal channels. Part 7. Kinematic and stress states of the workpiece under constrained extrusion. 4. Fully constrained extrusion

Abstract

The problem is being solved of determining the kinematic and stress states of the workpiece with a completely constrained extrusion of unequal channels under plane strain conditions with a misaligned punch and matrix. The force and geometrical parameters of the process are determined. Formulas are obtained for determining the main technological parameters of the process of extrusion of channels with a relatively thin horizontal bridge. Keywords: die forging, extrusion, misalignment of punch and matrix, plane strain, plastic flow rates, stresses. mt13@bmstu.ru
