| 摘要 |
The invention relates to a method for guiding and distributing high-energy radiation (18), in particular laser radiation, in the tool base body (7) of a bending die (3), in particular a V-shaped die (13), comprising a bending recess (11) in the tool base body (7) and a beam exit opening (17) arranged therein for locally heating a workpiece (2) bearing against a contact surface (10) of the bending die (3) by introducing high-energy radiation (18) from a radiation source (20) arranged outside the tool base body (7) into the tool base body (7) through a beam entry opening (22) and high-energy radiation (18) is discharged to the bending recess (11) through the beam exit opening (17). At least one concentrated high-energy radiation beam (21) is introduced into the tool base body (7) through at least one beam entry opening (22) and is at least partially deflected by at least one beam affecting arrangement (25) in the tool base body (7), expanded and guided through the radiation exit opening (17) onto the workpiece (2). |
