Definitions

  • the invention relates to a bending machine for flat material, comprising a machine frame, one on the machine frame arranged lower beam with lower beam tool and one on Machine frame arranged upper beam with upper beam tool, those for fixing the flat material relative to each other are movable, as well as a bending beam, one with a Bending beam tool can be equipped with a bending beam tool holder has and which is pivotable about an axis of rotation on the machine frame is held to that of the upper cheek and the lower cheek to bend fixed flat material.
  • Such a bending machine is from the prior art known (for example from DE-A-2 534 664).
  • the problem with such bending machines is that that the bending beam due to its length and the Bending the flat material occurring loads in their Deflects in the longitudinal direction and that this deflection a so-called crowning of the bending beam tool is compensated must become.
