Research of variables of pressing and torsion process of axial-symmetrical die forging

摘要

Pressing and torsion process is a modem process, in which deformation of metals appears as a result of combination stress. Forming die is loaded with axial force and technological, torsional moment. Reduction of value axial force is a result of transmitted tangential stress r to work-piece. These stresses substantially change the kinematics of flow. This work presents the results of author's laboratory's test for three shapes of impression of the dies. The aim of this work was to the assignment some relations between variables of the process.
