Zusammenfassung: | A lower tool for a bending machine, in particular die bending machine, includes a longitudinally extended base body, which has, on its bottom side, a tool shank for being received in a guide slot of a tool holder and optionally tool shoulders in the transverse direction, and at least one friction reduction device on the bottom side of the base body for reducing a frictional force between the bottom side and the tool holder in the event of a displacement of the lower tool in the longitudinal direction, wherein the at least one friction reduction device is configured such that a weight force of the lower tool acting on the tool holder, while applying a prestressing force in the direction of the weight force, causes a resulting normal force of the lower tool onto the tool holder that is lower relative to the weight force. |
