Abstract
A method for guiding and distributing high-energy radiation, in particular laser radiation, in the tool base body of a bending die, in particular a V-shaped die, includes a bending recess in the tool base body and a beam exit opening arranged therein for locally heating a workpiece bearing against a contact surface of the bending die by introducing high-energy radiation from a radiation source arranged outside the tool base body into the tool base body through a beam entry opening and high-energy radiation is discharged to the bending recess through the beam exit opening. At least one concentrated high-energy radiation beam is introduced into the tool base body through at least one beam entry opening and is at least partially deflected by at least one beam affecting arrangement in the tool base body, expanded and guided through the radiation exit opening onto the workpiece.
