Abstract
The invention relates to a method for bending a flat workpiece (), comprising the discharge of high-energy radiation () in the form of at least one planar fanned beam () from a bending recess () of a die arrangement () having a bending die () onto a workpiece () bearing against a contact surface () of the bending die () for the local heating thereof before and/or during a bending process. The one or more planar fanned beams (, . . . ) are produced by a number of optionally activatable radiation sources (, . . . ) which are arranged within the die arrangement () along the bending recess () or are caused by the distribution of a concentrated radiation beam () that is introduced from a radiation source () outside the bending dies (, . . . ) via a number of beam affecting arrangements (, . . . ) within the bending dies (, . . . ) and the exiting radiation () is thereby adjusted to the bending length () of the workpiece to be bent () via the number of planar fanned beams (, . . . ).
