  • the adjustment movement also includes the Segments taken and moved, seen in the direction of adjustment arranged in front of such a coupled or jammed segment are and are concerned with this.
  • the tool has a first group of segments that are interchangeable and / or at least one transverse to the bending line and a slot running parallel to its side surfaces have such slot width and slot depth that a bent edge of a workpiece in this slot fits
  • Tool has a second set of segments pointing in the direction the bending line relative to each other and to the segments of the first Group are adjustable, and that the sum of the maximum adjustment of all segments belonging to the tool, at least those in the direction the bending line width of an interchangeable segment or the distance of a slot from the side surface or surfaces of a once slotted segment and / or a neighboring slot of a multiple slotted segment.
  • a single interchangeable segment may suffice to cover this Realize invention.
  • the distance between a side surface and the closest and parallel slot is equal to the distance between the slots. So it can the first group of segments by one or more comb-like segments are formed, which is comb-like Maschinenteug already due to the multiple slits the coarse grid specifies so that a curved edge of a workpiece depending on its Overall dimensions inserted in one or the other of these slots can be made while using the required transverse dimension of the adjustable segments continuously to a desired size can be adjusted.
  • the adjustment path corresponds, as already mentioned, the distance between two adjacent slots, so that a Intermediate dimension between two such slots through the adjustable Segments can be set.
  • the first group of segments from one single segment could be formed, which then expediently with several arranged at regular intervals parallel slots can be provided, it being advantageous if the number of slots equal to or greater than the number of each other adjustable segments.
  • large workpieces can are edited, although only a single segment of the first group is present, which is not due to the large number of slots must be replaced, but in the introduction of a bent Edge of a workpiece in a matching slot allows while adapting the tool to the dimension this workpiece with the help of the adjustable segments can be done continuously.

  • the spreading means designed as springs can on the one hand on the inside boundary wall of the recess of the neighboring segment and on the other hand on the end face of this recess Support engaging bolt piece. So the bolt piece is enough not quite as far into the neighboring segment as its Recess or recess is deep.
  • the one in between and remaining distance, which changes when adjusting the adjustment path changes, is filled by the spring or springs, who increase this distance when relaxing and when Pushing the segments together are tightened accordingly.
  • the change in the distance of the end faces of the bolt piece from the inner boundary wall of the recess of the neighboring segment corresponds to the relative adjustment path between two adjustable ones Segments.

It is sufficient because of the above Arrangement of spreading means between the individual adjustable Segments, on the first or outer segment with such motor drive to attack when adjusting this outer segment follow the other segments of this movement to leave, so that next to this directly acted upon by a motor Segment also the other segments at least indirectly by motor be adjusted, so an operator is not required for this becomes.
  • the adaptation to can further improve different dimensions of workpieces could be that the adjustable relative to each other Slits running at right angles to the bend line Picking up a folded or bent edge of a workpiece exhibit. So the first and second groups of Segments practically match and / or all segments could also be adjustable relative to each other. But are additional non-adjustable segments exist, but could still be workpieces can only be edited on the adjustable segments if they have a correspondingly small overall dimension.
  • a practical embodiment of the invention could consist of six relative to each other in the direction of Bending line adjustable segments are provided that the width an interchangeable segment or the distance between one Side surface and a slot adjacent to this a slotted Segment or between the slots of a multi-slot Segment is about 30 mm and that the maximum adjustment of the adjustable segments away from each other is about 5 mm, so that the total adjustment adds up to the mentioned 30 mm.
  • This practical design example shows in concrete terms: like a continuous adjustment to different workpiece dimensions is possible in a simple manner, with the maximum Adjustment of the adjustable segments away from each other between this is such a small distance that he does Bending result not affected.
  • An embodiment of the invention can consist in that the segments of the first group to be replaced individually or all or different numbers of these segments together towards the bend line to reduce the overall dimension of the tool can be moved away from the other segments. It is known per se that the dimensions of such tools are thereby to change that individual segments shifted and thus out of Effect. In the present case, this can be done in Combination with the segments of the second group can be applied a certain exchange in the sense of an enlargement or Reduce the number of segments of the first group.
