摘要： The disclosure relates to punching tools for punching machines for punching plate-shaped materials. The punching tools have an upper tool part with an upper cutting edge and a lower tool part with a lower cutting edge that move axially with respect to each other. The upper and lower cutting edges are arranged to cut off a part of the workpiece in a punching stoke. The upper cutting edge and/or the lower cutting edge include one or more transition regions that separate the cutting edge into at least two adjacent portions. The transition regions include, in the punching direction with respect to the respective adjacent portions, a discontinuity that is adapted to cut the material cut off from the workpiece into two or more individual parts in the same punching stroke.

摘要： This disclosure relates to tools for punching machines for reshaping at least one portion of a plate-shaped workpiece. The tools have a first tool portion that includes a first device configured to be held in a first tool holder of the punching machine and a bending stamp having a bending edge and a second tool portion comprising a second device configured to be held in a second tool holder of the punching machine and a bending roller configured to cooperate with the bending stamp to reshape the plate-shaped workpiece. The bending roller is rotatable around a rotation axis running parallel to the bending edge. The bending roller comprises a sector-shaped notch formed along the rotation axis and formed, at least in part, by first and second bending shank edges.The bending roller comprises a plurality of second bending segments positioned on the rotation axis to rotate about the rotation axis.
