Definitions

  • the invention relates to a device for bending a hollow profile to produce a desiccant during or after bending filled hollow spacer frame for insulating glass panes with a guide and lying approximately in the feed direction of the hollow profile Holding device for grasping the front of the bending point located profile area, with one acting as a bending tool or serving device for detecting and pivoting the bend leg of the hollow profile and with an abutment to fix the inside of the resulting bend or curve and if necessary with one on the outside of the bending point Contact pressure relative to the abutment and to the hollow profile movable and can be pressed onto the outside of the hollow profile and / or tool immersed between side webs of the hollow profile in particular in the form of at least part of the at The profile web located on the outside of the bend Pressure roller, with a support for a side bar or a Part of a side web of the hollow profile and parallel to it a hold-down for the other side bar or part of the other side web of this hollow profile are provided and the Distance between hold-
  • Such a device for bending a spacer Inner frame or spacer frame for an insulating glass pane is from DE-B-32 21 986 as part of a machine for bending known.
  • Such a device for bending a desiccant filled spacer frame is also from EP-B-0 121 873 and such a device for bending a desiccant filled or initially unfilled hollow profile is from EP-B-0 318 748 known and these devices have proven themselves because thus bending of hollow profiles with or without desiccant filling with a narrow bending radius is possible without the Side webs in the bending area are deformed in this way or warps receive that the glass panes to be put on it no longer in satisfactorily and with sufficient accuracy at a distance can be held and sealed.
  • the invention is therefore based on the object of a device to create the type mentioned, in which the advantages of previously known devices with regard to good guidance and bending especially that located on the outside of the bending point Profile web of the hollow profile as well as that on the inside existing profile web remain and the Side bars in the bending area at an exact external distance according to the distance to be maintained between two glass panes can be held even if a thin-walled extruded hollow profile for example with wall thicknesses of the order of about a tenth of a millimeter or up to about two tenths of a millimeter or a hollow profile made of steel or stainless steel is to be bent, the spacer frame despite the reduced wall thickness sufficient strength in the bending area and in particular Should have bending strength.
  • the hollow profile hold-down devices serving during the bending are divided into one part of the part in front of the bending area and in front of the bending point Downholder is fixed, so the captured profile is practical holds stationary, while the rotatable part of the hold-down Material of the side web applied by him during the deformation through the bend and with the required and occurring Flow behavior of the material supports, but at least this Deformation and the resulting cold flow of the material not from an initially straight orientation into the curved position hindered so that a upsetting and bulging or the distance Wrinkles that enlarge the parallel side bar are avoided can be.
  • the rotating part of the hold-down is practical on the section of the side web of the hollow profile to be bent which, in turn, is a kind of turning or Swing movement should perform a fixed or over downholder running and protruding over the entire bending area could hinder.
  • the axis of rotation for the rotating part of the hold-down with the swivel axis of the Bending tool matches and one with the bending movement synchronous rotary movement of the rotatable part of the hold-down device is provided. It is easy to see that in this way the Hold down the deformation of the side web captured by him one supports straight in a curved course and with the necessary transportation of the material of the side bridge contributes to support around the bending axis. relative movements between the hold-down device and the area of the Side bars are kept as low as possible.
  • the support for the profile to be bent can also be used in the Bending area located rotatable part, the Axis of rotation is aligned with that of the rotatable part of the hold-down device, and the common axis of rotation of the rotatable parts of the hold-down device and the support are at right angles to the hold-down surface and the contact surface and thus at right angles to the side bars arranged of the profile. Then both side bars become practical acted upon by a rotating part and yet still kept at a distance, so that even introduction of Bending and possibly low frictional forces approximately symmetrical Way and at least largely the same size at the same time occur on both side bridges. So the danger of Squeezes and uneven bending of the parallel Sidewalls due to the largely synchronous loading moving parts as low as possible.
  • the tightening of material into and around the bend area also favored in the area of the side bridges can consist in that the fixed part of the hold-down device compared to the bending hollow profile has little play or a sliding fit. On the one hand, this leads to a sufficiently good clamping of the that part of the hollow profile lying in front of the bending position holds that Hollow profile but at the same time especially in the area of Side bars not so tight that not some material in the Bending area and around this could be tightened.
  • abutment is transverse to it Longitudinal deflection, in particular pendulum, in the way is stored that its effective area between the pad and hold-down can be moved back and forth.
  • the abutment has a kind of "floating" bracket and is between during the bending process Support and hold-down device for the profile to be bent the best location moves, so that the inner space may become too large Tensions at this point with a jam, for example between abutment and hold down or between abutment and Bearings can be largely avoided.
  • the abutment can be swiveled around an axis, it can be against the axis on the actual abutment side protrude from the opposite side and with this protrusion a stop, which limits the pendulum movement.
  • the protrusion beveled, so that the pivot bearing protruding part of the abutment comes to rest when the Compression spring lifts the abutment in the bending area.
  • the rotatable part of the hold-down device and the abutment can connected to one another, in particular connected in one piece. This is a synchronous and even as well as simultaneous Movement of both the hold-down device and the rotatable part possible so that the inside of the bend on the one hand but also at least the inside of the side bar on the other hand during the Bend pulled from the parts acting on it to a certain extent and be carried along. Relative movements between abutment and Hold-down device that leads to corresponding constraints on the hollow profile and could lead to its bridges are avoided. However, this is also possible if the rotatable part of the hold-down device and that Abutments are not connected to each other, but these parts or they hold parts have a common drive.
  • the abutment can on the inner crossbar of the Hollow profile attacking abutment surface distributed transverse Grooves for the engagement of projecting on the inside of the hollow profile

  • hollow sections of different widths, their side webs are extended via an inside crossbar with which device according to the invention can be detected and bent because the engage protruding side webs in the grooves of the abutment can, with a groove suitably aligned with the support or matches and the further grooves spaced apart in their distances from this first, which corresponds to the edition Groove are dimensioned so that profiles of different widths are recorded can.
  • each can expediently be a Hollow profile with a web-engaging groove the rotatable part of the Form hold-down, that is, the spaced from the support Grooves engage with their inner wall on the inside of the Ridges, while the outer wall comes to rest on the outside and there the function of in this case in one piece with the abutment connected rotatable part of the hold-down can exercise. Consequently can have different widths of such profiles with one and the same Abutment detected and according to the invention with a rotatable part hold down and processed.

  • the Dimensional accuracy between the side bars also precise in the bending area can be observed because the hold-down is divided and in the most deformed area of the side bars rotatable part of this hold-down is used, the Rotational movement the flow of the material around the bend supported and at least hindered as little as possible.
