More Information
Summary:The invention relates to a process and a device for compression rolling a workpiece (W), at least some parts of which have the shape of a hollow cylinder or a hollow truncated cone and which is formed into a vehicle wheel by the compression rolling process. In order to compression roll the workpiece on a rotatable main spindle with a main spindle mount (2) of a compression rolling device, the workpiece (W) is axially clamped between the main spindle with the main spindle mount (2) and a setter (3) and is rotated about the main rotational axis (HA) of the main spindle by means of the main spindle with the main spindle mount (2). The compression rolling process is carried out by means of at least one compression roll (4) arranged radially outside of the hollow cylindrical or hollow truncated cone-shaped workpiece (W). The invention is characterized in that a radially inner rotatable eccentric tool ring (5) is arranged radially within the workpiece (W) as a counter bearing for the workpiece (W) during the compression rolling process, said eccentric tool ring being at least radially movable and having a dedicated rotational axis (5A) which can be moved radially in parallel to the main rotational axis (HA) between a first position and a second compression rolling position that is radially offset to the first position. In the compression rolling position, the main rotational axis (HA) of the main spindle with the main spindle mount (2) also lies radially within the bore or the inner diameter of the eccentric tool ring (5) but is no longer aligned with the dedicated rotational axis (5A) of the eccentric tool ring (5).
