Definitions

  • the invention relates to a method and a device with the Features of the introductory part of the main claim method and of the device main claim.
  • Bending devices for hollow profile strips to from these spacer frame to bend with integrally formed corners are in various embodiments known.
  • EP 0 461 100 A US Pat. No. 5,136,871 A
  • EP 0 318 748 A EP 0 318 748 A.
  • This known bending device has a holding device arranged in front of the bending point for to be bent hollow profile strip, on the hollow profile strip of attacks above and below. Furthermore, has the well-known Bending tool a support for the one side web of the hollow profile and a hold-down for the other side web of the hollow profile. The support and the hold-down act as jaws that are attached to the Hollow profile strip can be applied.
  • the bending device known from US-A-6 023 956 has a Bending tool with an abutment that is one of its actual Abutment surface outgoing "continuation leg" has.
  • the continuation leg of the abutment pivots together with the Bending tool when a hollow profile strip is to be bent. Furthermore deforms the bending abutment when performing the bending movement the directly acted upon by him crosspiece of the hollow profile strip towards the neutral fiber of the hollow profile strip.
  • the invention is based on the object, a device of to improve the type mentioned at the outset ("bending head") that with the bending device and steel profiles (in particular thin-walled steel profiles) to spacer frames for insulating glass panes can be bent.
  • Essential for the success of the method and for the success of the particular suitable for carrying out the method Device is that on the outside of the hollow profile strip Delivered bending beam during the bending of the hollow profile strip rests against the outer wall and the hollow profile strip from the outside supports and that the bending abutment together with the outside adjacent bending cheek is pivotable.
  • the bending process is advantageously supported by the fact that the Bending cheek when bending the hollow profile strip along this, and While away from the bend, it moves while on the outside the hollow profile strip rests.
  • the inventive method and the invention provided Device allow it, even those hollow profile strips, in which the side flanks protrude beyond the inner wall of the hollow profile strip, so to turn, without the protruding sidewalls after the bending process are wrinkled.
  • Bending head 1 are a stationary during bending lower guide 3, an upper guide cheek 4, two lateral support jaws 14, 15 for the bent hollow profile strip 2, one about an axis 6 pivotable Biegewiderlager 5 and a bending cheek 7, which at one order the same axis 6 as the flexural damper 5 pivotable lever. 8 is arranged.
  • the distance of the guide 3 from the guide cheek 4 is, for example by adjusting the upper guide cheek 4 to the dimension (height) the hollow profile strip 2 customizable.
  • the bending cheek 7 For advancing the bending cheek 7 to the lower in Fig. 1 outside the hollow profile strip 2 is the bending cheek 7 on an arm 9 of a two-armed lever 10 mounted around an axis 11 on the lever. 8 is pivotally mounted. On the other arm 12 of the two-armed lever 10 attacks a pressure cylinder 13, through which the two-armed Lever 10 is pivoted so that the (lower) bending cheek 7 of below against the outside of the hollow profile strip 2 to be bent is created.
  • the axis 6 and the axis lie around the the bending cheek 7 is mounted on the two-armed lever 10, in the in Fig. 1 shown starting position substantially in one of Hollow profile strip 2 vertical plane.
  • the bending support 5 (see also Fig. 9) has at its front, the hollow profile bar 2 facing head 16 a flattened Area 17, which in the position of the bending stock 5 of Fig. 1 of the (in Fig. 1 facing upwards) inner wall of the hollow profile strip 2 is facing and preferably applied to this.
  • the flexural dam 5 mounted on the upper guide cheek 4 about the axis 6 pivotally be.
  • the hollow profile strip 2 such a sheet steel, wherein the side walls of the Hollow profile strip 2 over the inner wall of the hollow profile strip 2 survive.
  • a hollow profile strip 2 For bending a hollow profile strip 2 is by pressing the Pressure medium cylinder 13, first the bending cheek 7 to the (down pointing) outside of the hollow profile strip 2 is applied and takes these, as shown in Fig. 4, preferably in a corresponding to the Outside of the hollow profile strip 2 contoured surface, so that the outside of the hollow profile strip 2 well supported during the bending process is. Then, the bending stocker 5 from the in Fig. 1 in full lines drawn position in the dotted in Fig. 1 drawn position pivoted (arrow 24), the inner wall the hollow profile strip 2 through the head 16 of the bending stock 5 can be deformed in areas to the inside.
  • the Biegewiderlager 5, including its head 16, can have a width that is so is dimensioned that the bending abutment 5 between the over the inner wall received on projecting side walls of the hollow profile strip 2 is and the side walls in the bending area, in particular during the actual bending process is supported (see Fig .. 4).
  • the pivot lever 8 is with the bending cheek 7 and the bending stock 5 in the in Fig. 1 shown Position swung back. Then the hollow profile strip 2 advanced so far, until the next point in a corner through Angling the hollow profile strip 2 is to produce, in the bending point (Arrow 20) is aligned.
  • One of the two cheeks (In the embodiment shown, the jaw 14) is adjustable to adjust the bending head 1 different width hollow profile strips 2 to be able to and between the individual bending operations the baking 14, 15 can be removed from each other, so that the advancing the Hollow profile strip 2 is simplified.
  • FIGS. 5 and 6 the flexural deflector 5 is in its operative position (in FIG 1 dashed line drawn) shown.
  • a rotary motor 20 is provided which has a pivoting lever 21 drives, via a coupling arm 22 with a to the Axis 6 pivots lever 23 attacks, so that the bending abutment 5 formed with the manner of a parallelogram drive Drive in the sense of double arrow 24 in Fig. 1 are pivoted can.
  • the pivot axis 6 of the lever 8, on which the bending cheek 7 is arranged is, is the same axis about which the bending stock 5 swiveled is, so that this is also the axis at the same time, around the one Hollow profile strip 2 is angled.
  • Figs. 5 and 6 it is shown that the bending head according to the invention 1 among other things also suitable for bending hollow profiled strips 2 is, whose side walls on the inner wall of the hollow profile strip. 2 survive, as for example in hollow profile strips made of sheet steel often the case.
  • Figs. 7 and 8 show the bending head of Figs. 5 and 6 in its Position after bending a hollow profile strip by 90 °.
  • the attacking from the top of the hollow profile strip 2 and in the shown Embodiment between the upwardly projecting side walls engaging guide cheek 4 is together with the bearing on her Biegewiderlager 5 after opening the jaws 14, 15 easily replaceable, around the bending head 1 to other widths of hollow profile strips to be able to adapt. Analogously, the bending cheek 7 easy against such with a different width or profiling be replaced.
