Abstract

A tool includes first and second tool parts that move toward one another, at least one processing device provided on the first tool part, and at least two counter devices provided on the second tool part. The processing device and the counter devices are rotatable relative to one another about at least one positioning axis, and the counter devices are aligned relative to one another along a direction of relative rotational movement of the processing device and the counter devices. The processing device and a first counter device are allocated to one another by at least a first defined processing parameter, and the processing device and a second counter device are allocated to one another by at least a second defined processing parameter. The first processing parameter is different than the second processing parameter.

First claim

What is claimed is:

1. A tool for forming workpiece, the tool comprising:
a first tool part and a second tool part, which can be moved towards one another
in a direction of travel for forming the workpiece-between the first and second tool parts;
a forming device provided on the first tool part and comprising a bearing surface; and
two counter forming devices provided on the second tool part and each comprising a forming surface, the first tool part comprising the forming device and the second tool part comprising the two counter forming devices being rotatable relative to one another about a positioning axis, the two counter forming devices being aligned relative to one another along a direction of relative rotational movement of the first tool part and the second tool part, wherein, by rotating the first tool part and the second tool part relative to one another about the positioning axis, the forming device on the first tool part and a first counter forming device of the two counter forming devices on the second tool part are allocated to one another to produce a first shape on the metal sheets by an interaction of the bearing surface of the forming device and the forming surface of the first counter forming device, and the forming device on the first tool part and a second counter forming device of the two counter forming devices on the second tool part are allocated to one another to produce a second shape on the workpiece by the interaction of the bearing surface of the forming device and the forming surface of the second counter forming device, the first shape being different than the second shape.

2. The tool of claim 1 , wherein at least one of the first tool part and the second tool part can rotate about a tool rotation axis, the tool rotation axis forming the positioning axis, about which the first tool part comprising the forming device and the second tool part comprising the two counter forming devices can be rotated relative to one another.

3. The tool of claim 1 , wherein the two counter forming devices of the second tool part are aligned relative to one another along a circular path about the positioning axis at a distance from the positioning axis, which is adapted to a distance of the forming device from the positioning axis.

4. The tool of claim 1 , wherein the first shape is produced for preparative processing of a portion of the workpiece and the second shape is produced for subsequent processing of the portion of the workpiece.
