  • Device and method for bending a workpiece
    Patent number: 9003847
    Abstract: The invention relates to a method for bending a flat workpiece (2), comprising the discharge of high-energy radiation (19) in the form of at least one planar fanned beam (24) from a bending recess (12) of a die arrangement (3) having a bending die (7) onto a workpiece (2) bearing against a contact surface (11) of the bending die (7) for the local heating thereof before and/or during a bending process. The one or more planar fanned beams (24; 24a. 24b, . . . ) are produced by a number of optionally activatable radiation sources (22a, 22b, . . . ) which are arranged within the die arrangement (3) along the bending recess (12) or are caused by the distribution of a concentrated radiation beam (40) that is introduced from a radiation source (39) outside the bending dies (7a, 7b, . . . ) via a number of beam affecting arrangements (23a, 23b, . . . ) within the bending dies (7a, 7b, . . .

  • Connection piece for a heat exchanger
    Patent number: 6474698
    Abstract: A metallic connection piece for an all-metal heat exchanger is capable of being used for a plastic hose coupling. The connection piece (20) has a double bead as a stop region with two integrally formed anti-twist retaining means (26, 27) that engage into axial grooves (40, 41) of a hose coupling (31) and ensure fault-free mounting.
