Method and device for influencing the deformation behavior, in particular the springback when forming workpieces in clocked forming and processing stations, in particular during bending in progressive dies

摘要

The invention relates to a method for influencing the deformation behavior, in particular the springback when forming workpieces (1) in clocked forming and processing stations, in particular during bending in progressive dies, in which a workpiece (1) is processed one after the other in a succession of cyclically linked processing stations is subjected to at least one transformation. Here, the workpiece (1) during the passage through the clocked linked processing stations before and / or after at least one Umformungsstation (13) of an adaptively guided and at least a portion of the workpiece (1) subject temperature (6) subjected to the Forming behavior of at least this area (9) of each individual workpiece (1) in this forming station (13) influenced such that the stress state, in particular the springback and / or the residual stresses of the material of the workpiece (1) after the forming (13) a setpoint for Achievement of the desired finished part geometry or reached to be reached intermediate geometry of the workpiece (1) to be formed. Furthermore, a device suitable for carrying out the method will be described.
