Zusammenfassung:The invention relates to a bending die (3), particularly a V-shaped die (13), comprising a tool base body (7) with a contact surface (10) for contacting the workpiece (2) to be bent by a bending punch (5), a groove-shaped bending recess (11) in the contact surface (10) and at least one beam exit opening (17) in the bending recess (11) and extending along thereof, which is configured to discharge high-energy radiation (18) onto a workpiece (2) bearing against the contact surface (10) in order to heat the deformation zone of the workpiece (2). An arrangement of diode laser bars (20) is fixed in the interior of the tool base body (7) for producing the radiation (18). Said diode laser bars (20) are arranged at least approximately uniformly along the longitudinal direction (27) of the bending recess (11) behind the beam exit opening (17) in the tool base body (7).
