  • Maximum Reduction of Axial Forging Load in Cold Upsetting with Torsion Die Motion

抄録

<p>To reduce the axial forging load in cold upsetting process, torsional oscillation was superposed with axial forging load. A cylindrical aluminum workpiece was simultaneously compressed with a maximum speed of 0.1 mm/s in z direction and twisted with a maximum angular speed of 0.5 rpm around the z-axis at room temperature. In case of the aluminum workpiece with an initial aspect ratio (height/diameter) of 1.0, a maximum reduction in the axial load was found to be approximately 80% for a rotation/compression speed of approximately over 300 °/mm.</p>
