Claims15
A tool for a punching machine, the tool comprising:
- a portion to be received in a tool holding device of the punching machine;
- and
- a tool insert movably supported in the portion of the tool in a manner such that the tool insert can be moved relative to the portion of the tool in a direction of a longitudinal axis of the tool,
- wherein the portion of the tool comprises a drive mechanism to move the tool insert in an oscillating manner, and the drive mechanism comprises:
- a hollow wheel having a circumferential gearing for driving the drive mechanism,
- a transmission element which is circumferentially surrounded by the hollow wheel, wherein one of the hollow wheel and the transmission element has a surface having hills and recesses, and
- rolling elements axially arranged between the hollow wheel and the transmission element for generating an oscillating movement of the transmission element.
