The Principle Of Rolling Forging Machine
Jan 05, 2018

The lower die is driven by a torque m and rotates around the vertical axis of rotation. The upper die axis has an alpha tilt angle relative to the lower die axis. The workpiece is placed in the lower mold, and the upper die convex is contacted with the initial contact of the workpiece, because the upper die is tapered. If an F force is applied to the upper die, the pressure into the workpiece is δf. The convex surface of the upper die and the workpiece at this time become a parabolic surface. Once the mold is rotated, the contact surface under pressure on the workpiece becomes a half parabolic surface, the AP with shadow representation.
