ABSTRACT:
The well-known Grob cold forming machine for carrying out the Grob method of impact roll-shaping utilizes rolling head carriers that move toward and away from the workpiece wherein each rolling head carrier is provided with rotatably driven rolling heads. Journalled in the rolling heads are impact formers or rollers which, during rotation of the rolling head, within their circle of rotation perform single forming steps on the workpiece which is mounted on a mandrel. In addition, each rolling head carrier carries a freely rotatably journalled pressure roll having an axis parallel to or angled relative to the mandrel axis, the pressure roll being located outside the rotational circle of the impact former. Via the use of pressure rolls, mainly axial shaping is achieved and thereafter, via the use of the impact former, mainly radial shaping is achieved in the same set-up and on the same mandrel.
