  • Patent number: 11565296
    Abstract: 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.
    Type: Grant

  • Patent number: 7997115
    Abstract: The invention relates to a folding device (1) for a bending press, in particular an edging press for a 180°-folding brace on a workpiece (2) with a forming die (3) comprising a V-groove and a forming stamp (4) adjustable thereto and comprising a wedge extension (26) and with a folding die (5) arranged adjacent to the forming die (3) and forming a support surface (33) in a plane (23) extending perpendicular to an adjustment direction of the forming stamp (4). A tool mount (7) with the forming die (3) and the folding die (5) is arranged adjustably on an upper side (18) of a table beam (9), in a direction perpendicular to a bending plane (22), forming a gap (27) for mounting the wedge extension (26) for the folding procedure.
