Definitions

  • the invention relates to a method for folding over a flanged edge of a workpiece by Rollfalzen with at least two folding steps according to the preamble of claim 1. Such a method is disclosed in JP-A-01249222.
  • a known flanging device for folding over a flanged edge by means of roll creases (EP 0 525 759 B1) comprises a tool unit which can be moved in a controlled manner by means of an articulated arm robot. On the tool unit a folding roller is rotatably mounted, which is rollable under pressure application and with certain angular position along and in contact with the flanged edge to the assignment.
  • the workpiece with the folded edge already folded by about 90 ° before the folding operation is inserted into a folding bed for holding the workpiece and to support the entire length of the flanged edge.
  • the production of a joint connection between two sheet metal components is shown here, wherein the crimping edge of the crimping edge of an outer sheet metal component is crimped around an edge of a second sheet metal component.
  • the folding process takes place here in two stages, by the cylindrical seaming roller guided under pressure with an angle of attack in such a way along the flanged edge is that this is folded in a first folding step as Vorfalzung starting from the already bent by 90 ° flanged edge by another 45 °. Subsequently, the cylindrical folding roller is pivoted with its roller axis for a second folding stage, such that for a Endfalzung the flanged edge is completely folded over by 180 °.
  • a device for producing a joint connection is known (EP 0 904 167 B1), to which a flanged edge is folded by processing by 180 °, wherein a reinforcing member is connected when joining a vehicle roof in the region of a sliding roof section.
  • the fold of the sheet metal flange or the flanged edge must be done on a dimensionally exactly predetermined bending line.
  • the joint connection is carried out here by bending operations by means of expensive Greschieber and folding jaws.
  • a flanging device for folding over a flanged edge by Rollfalzen in which a number of folding rollers are arranged with different angular positions one behind the other on a tool unit.
  • These Crimping device is used to convert a flanged edge of a sheet metal part to a stable edge flange of a workpiece by 180 °.
  • the peripheral edge of the stable edge flange serves as a support for the formation of a correspondingly defined bending line.
  • this device is not suitable because the roll seams both the flanged edge of a sheet metal part and the edge flange of the other sheet metal part would bend undefined.
  • the object of the invention is to develop a generic flanging so that in a multi-stage folding from a flat edge region of a workpiece in a first folding step a dimensionally predetermined, exact Abkantline is formed with a correspondingly dimensionally predetermined position of the flanged edge.
  • the Abkantline is supported in its formation exactly opposite to the folding roller by the co-moving support roller edge, whereby a correspondingly accurate and clean bending edge is obtained.
  • a linear straight Abkantline can be accurately formed.
  • bent bending lines according to given curves are also advantageously possible. The bending process is fast, easy and inexpensive feasible by means of an articulated arm robot.
  • the Falzrollenburnse and the support roller rotation axis are in a transverse plane to the flanged edge, so that the contact points of the folding roller and the support roller are located directly opposite to the flanged edge.
  • the folding roller is rotatably mounted on a Falzrollenarmeteil, wherein the Falzrollenarmeteil by means of an actuator from a basic position with a mutual distance between the folding roller and support roller in a functional position, in which abut the folding roller and the support roller edge at the flanged edge, is displaced controlled.
  • the folding roller is brought in a linear sliding movement of the support roller, with a guide carriage assembly which is adjustable by an electric and / or hydraulic and / or pneumatic drive.
  • the support roller may be disk-shaped, preferably flat double-cone-shaped, wherein the peripheral edge then forms directly the support roller edge.
  • the folding roller is preferably made cylindrical in the region of its rolling surface, with a rolling surface width corresponding to the crimping edge width, whereby a good folding result is achieved.
  • a conical surface opposite to the rolling surface of the folding roller can also be used as a contact surface for the flanged edge during the folding operation.
  • a flat contact with the support roller in addition to the system on the support roller edge is not required for each use.
  • the folding process is carried out in a proven sequence according to claim 2 such that in a first folding step, the adjacent rolling surface of the folding roller is guided at an angular position of about 30 ° for a corresponding Bördelkantenumbiegung by 30 ° along with the support roller along the flanged edge.
  • the tool unit is controllably controlled for a second folding step so that the adjacent rolling surface of the folding roller is guided at an angular position of about 60 ° for a further Bördelkantenumbiegung to 60 ° along with the support roller on the Bördelmé along.
  • the bending line and bending edge is stably formed in the predetermined manner, so that for further folding steps usually no support on the bending edge by a revolving support roller edge is required more.
  • a further contribution of the flanged edge for example to a total of 180 °, can then be carried out according to claim 3 by a further robot-controlled tool unit with a cylinder folding roller known per se.

  • the first sheet-metal component 3 and the second sheet-metal component 4 form an example of a frame of a sunroof cutout, in which the edge 5 of the second sheet metal component 4 form a wall 6 of a channel 7 when the folded edge 2 of the first sheet metal component 3 is folded over, as shown particularly in FIG it can be seen in which the flanged edge 2 is completely crimped around the edge 5 of the second sheet metal part 4.
  • the first sheet metal component 3 and the second sheet metal component 4 together form a workpiece and are held in a folding bed 8 of the hemming apparatus 1.
