A is rotatable on the tool unit Folded roller stored under pressure and with a certain angular position can be rolled along and in contact with the flanged edge for its folding.
  • the workpiece with the one already bent by about 90 ° before the folding process Flanged edge is in a holding device for holding the workpiece and inserted to support the area of the flanged edge.
  • a holding device for holding the workpiece and inserted to support the area of the flanged edge.
  • the folding process takes place here in two stages, with the cylindrical folding roller underneath Print with an angle of attack such along the flanged edge is that this is folded in about 45 ° in a pre-fold. Subsequently the cylindrical folding roller with its roller axis is used for a second folding stage pivoted in such a way that the flanged edge is completely folded for final folding is turned by 90 °.
  • the object of the invention is a generic device for folding a flanged edge of a workpiece by roller folds so that a good folding result can be achieved with less effort.
  • the tool unit on the drive is about a pivot axis pivoted and at least by a certain pivot angle two working positions swiveling.
  • the at least two working positions is a folding roller rotatably mounted on the tool unit assigned, the at least two assigned to the working positions Folding rolls differently designed and with regard to the flanging edge folding have differently effective folding roller peripheral surfaces.
  • For an at least two-stage folding of the flanged edge is for a pre-fold the tool edge with the first folding roller in its functional position led along the flanged edge. For the subsequent final fold then pivoted the tool unit into the second working position and with the second folding roller in its functional position along the flanged edge guided.
  • the folding rollers used have different ones for the respective process effective folding roller peripheral surfaces, with which in particular pre-folds and the final folding can be done.
  • the necessary different angles of attack of the folding roller peripheral surfaces with respect to the According to the invention the crimped edges are thus formed by the differently designed ones Folding rolls are provided that are only in their just required Functional position must be pivoted. So that by means of a Robot articulated arm the tool unit in all folding stages over the same Movement path are performed, in contrast to the prior art, where complicated changes in the path of movement of the robot articulated arm in the individual folding levels due to the tilting of the folding roller are.
  • a particularly simple geometric arrangement results according to the claim 2, by the roller axes of rotation of the at least two folding rollers radially aligned to the swivel axis in a plane perpendicular to the swivel axis lie and include the swivel angle.
  • the swivel axis is for a folding process expedient approximately parallel to the folded edge and approximately perpendicular to the workpiece surface adjacent to the flanged edge set.
  • the different working positions can be approached by Swiveling the tool unit back and forth about the swivel axis.
  • the working positions can, however, also be continued by turning in one Direction are approached, with the pivot axis as the axis of rotation is trained.
  • To the different folding rollers by simple swivel movements to bring them into their functional position, it is necessary the folding roller circumferential surfaces effective for folding the flanged edge approximately to be arranged at the same distance from the swivel axis.
  • the folding roller peripheral surfaces of the individual folding rollers each in accordance with the existing requirements and conditions with regard to a pre-fold and final fold for certain desired fold configurations be executed.
  • the different folding roller peripheral surfaces in a simple manner as conical surfaces with different cone angles and / or in particular for the final fold as cylindrical surfaces, which means that each of the individual Folding rollers have different angles of attack with respect to the flanged edge for an assigned gradual roll fold can be reached.
  • three folding rollers are provided at a swivel angle distance of 120 ° each.
  • a first folding roller is a tapered roller with a tapered surface for one The flanged edge is folded over in a first pre-folding stage by approximately 30 °.
  • a second folding roller is accordingly a tapered roller for a second pre-folding stage designed with a fold of the flanged edge by about 60 °.
  • the third folding roller is designed as a cylindrical roller.
  • the support rollers are in a simple embodiment according to claim 6 non-rotatably, preferably integrally and uniformly connected to the folding rollers and arranged pointing to the pivot axis, so that they on a Roll the guideway next to the flanged edge.
  • the tool unit can be constructed as an independent component according to claim 7 and flange-mounted on the end of a robot joint arm. By different The same tool unit can possibly have different flanges Robot articulated arms can be combined.
  • the device according to the invention can be used both for simple flanging formation as well as according to claim 8 for a joint connection of two Sheet metal parts are used.
