Definitions

  • the invention relates to a method for generating continuously curved sections in hollow profile strips, in which the hollow profile strip under one Hold-down device between guide jaws, from below supported, pushed forward and after the hold-down device from the conveying direction of the hollow profile bar a ramp surface inclined to the conveying direction a bending lever is deflected.
  • Spacer frames and devices for Manufacture of these are from DE-GM 87 05 796, DE-PS 32 21 881, US-PS 4 836 005, FR-PS 2 449 222 and DE-OS 32 21 986 are known.
  • DE-OS 33 12 764 from which it is known to use hollow profile strips for spacers for insulating glass panes, where in the area of the bending point from the inside against the Hollow profile bar attachable mandrel is provided.
  • the Bending is done by pivoting a jaw, whereby the other end of the profile bar between one movable jaw and one on the inside abutment abutting the profile strip becomes.
  • a problem with the known bending devices is that for use with insulating glass panes required sharp-edged turns cannot always be easily reached because partly there is a risk that the walls of the hollow profile strip tear during the bending process and the side surfaces the hollow profile strips in the corner area, i.e. not always flat where they have been bent run, but have corrugations that the subsequent processing of the spacer frame, especially the coating of the side surfaces the spacer frame with sealant or adhesive complicate and hinder.
  • DE-AS 21 28 717 describes a method for Apply a metallic spacer to the Slice edges of one of the rectangular glass plates an insulating glazing known. With this procedure the spacer is continuously with a disc parallel Surface on a first edge of the pane the horizontally lying glass plate and then attached. Then the spacer with a disk-parallel surface on created and fastened the next pane edge. This Steps are repeated until the spacer frame is attached to all edges of the pane. Then the spacer is cut off and its Ends joined together.
  • hollow profile strips become spacers for insulating glass panes bent by this advanced during bending and a bending lever oscillating to and from the abutment is moved away, while moving away the profile of the bending tool and with the next movement of the bending tool a neighboring point of the profile towards the abutment applied to the previously bent point and is bent.
  • This can vary depending on the feed rate of the profile and the bending frequency or the bending stroke of the bending tool different Generates arcs and radii of curvature become. But there are no continuously curved arches, but preserved sections of the hollow profile strip, that are angled several times.
  • Bending machines for hollow profile bars are also known, which are equipped with rollers. So describes DE-OS 30 34 436 a roll bending machine, which has three rotatably driven rollers, the hollow section bar of two rollers in plant is held to the third roller. The radius of the Curvature in the hollow section bar corresponds to the radius the third roller, around which the hollow section bar was bent.
  • the object of the invention is a method and to provide a device with which continuously curved hollow profile strips can be, the radii of curvature and the length of the curved section of the hollow profile strip are largely freely selectable.
  • the hollow profile strip to be curved from a feed device that is advantageous is designed as a gripper or has a gripper, is advanced.
  • this saves drives for the roles, like this for the known devices are necessary and offers versus pulling the hollow profile strip has the advantage that manufactured in this curved or bent areas (Corners) are not deformed again.
