METHOD FOR BENDING A WORKPIECE
The invention relates to a method for bending a workpiece (1) of sheet metal, whereby a deformation region (6), in particular a strip-shaped region, on the workpiece (1) containing the bent edge to be produced (5) is heated before and/or during the bending process to a deforming temperature below th...

| Abstract | The invention relates to a method for bending a workpiece (1) of sheet metal, whereby a deformation region (6), in particular a strip-shaped region, on the workpiece (1) containing the bent edge to be produced (5) is heated before and/or during the bending process to a deforming temperature below the fusion temperature of the metal to increase deformability locally. In order to reduce undesirable deformation due to shrinkage stress, the workpiece (1) is heated before and/or during and/or after the bending operation in at least one heating zone (11) that is different from the deformation region (6) by means of the application of energy from outside the workpiece (1) starting from an initial temperature to a processing temperature below the fusion temperature of the metal. |
