METHOD FOR PRODUCING A CABLE TRAY COMPONENT, BEAD PRESS FOR PRODUCING SUCH A CABLE TRAY COMPONENT AND CABLE TRAY COMPONENT PRODUCED THEREWITH

The invention relates to a method for producing a cable tray component which is made of metal and designed, for example, as a cable tray (1) or cable tray cover and has a sequence of beads (5) along its longitudinal extent, which beads are stamped into the workpiece (14) used to form the cable tray component (1) by means of a stamping process, wherein, for the process of bead stamping, the workpiece (14) is clamped in a hold-down element (N) adjacent to or in the transition to a bead (5) to be created. A special feature according to a first embodiment of the method is that the workpiece (14) is held in the hold-down element (N) by a form fit which acts in the radial direction towards the bead (5) to be created and is produced by at least one form-fitting edge (16, 17) pressed into the surface of the workpiece (14), as a result of which at least one indentation following the shape of the bead (5) is introduced into the material of the workpiece (14) by the hold-down element (N) before the bead (5) is formed. According to another embodiment of the method, to create the bead, following its outline geometry, the workpiece in the bead edge region is reduced in terms of its material thickness in the direction of the bead to be created, over a portion extending in the radial direction towards the bead to be created, by at least one stamping bulge located on the hold-down element, and is thus lengthened in the direction of the bead to be formed. The invention also relates to bead presses for producing a cable tray component which is made of metal and has a sequence of beads along its longitudinal extent using this method, and a cable tray component produced therewith.
