Definitions

  • the present invention relates to a bending machine for bending of thin-walled tube profiles, especially spacer profiles or edge profiles for sealed insulating glass units having a virtually rectangular cross-section and where the bending is effected across a bending pin.
  • a completely different problem with the bending machines is that they are only immediately capable of bending spacer profiles having the same cross-sectional dimension. Essentially spacer profiles have the same height given by the depth of the groove of the window, whereas the width varies considerably depending on the distance provided between the glass sheets and whether it is a matter of double or triple pane units.
  • the known bending machines cannot be instantly readjusted to the various widths of spacer profiles. From EP-A2- 0 241 174, however, is known one single example of a bending apparatus, which immediately can bend spacer profiles of different widths.
  • the apparatus comprises two wringing heads being provided with a through-going cylindrical bending pin in the center line of the wringing heads, and where one wringing head is laterally displaceable relatively the other via a compressed air cylinder.
  • this apparatus suffers from the same drawback as the apparatus according to EP-A2- 0 318 748, viz. that the profile collapses at the corner at the bending.
  • the object of the invention is to provide a bending machine meeting with above-mentioned requirements for performing the bending and which may without adjustment bend spacer profiles having different widths.
  • a bending machine which is characteristic in comprising two separate, situated opposite one another, bending pins on lateral guides and reaching across the upper side of the profile and where the outer ends of the bending pins comprise a portion, which during the bending process initially deforms the upper side of the profile locally at the sides, and where the bending pins furthermore are designed such that the side walls of the profile during the further bending can be accommodated in a groove at the base of the bending pins at the lateral guide for stabilizing the side walls.
  • the side walls of the profile are guided up into the grooves at the base at the lateral guides and are stabilized.
  • the bending pins are preferably designed having a rivet-like shape with a head on a stem or neck, where the head constitutes the outer portion of the pin, and the groove being formed at the stem between the lateral guide and the face of the head facing towards the lateral guide, this groove guiding the side wall of the profile during bending.
  • the side edges are then bent across the stems.
  • the pins may of course also be designed in the actual guides and only show the faces required for the bending.
  • the machine may instantly be applied to bending of profiles having different widths.
  • One lateral guide is usually stationary at the side of the profile infeed in the machine and the other is displaceable relative thereto.
  • the bending machine consists in principle of a frame 2 with a plate-shaped top 4 supporting the bent portion of the profile during the bending process.
  • the machine has an automatic infeed for the profiles but is otherwise computer controlled for automatic bending of the profiles.
  • the position of the bends is determined by a counter 8 in the feeding path of the profiles.
  • the reference numbers 10, 12 designate a bending head and a bending actuator, respectively, while 14 designates a sawing arrangement for shortening of the profiles.
  • Fig. 3 of the drawing reference number 16 is a spacer profile between a stationary lateral guide 18 and relative thereto displaceable other lateral guide 20, each carrying bending pins 22 positioned opposite one another.
  • the displaceable lateral guide is fastened at the end of a spindle 24 slidably embedded in a sliding bush 26.
  • the lateral guide 20 is via the spindle connected to an air cylinder 28, which via the automatic control is activated and brings the lateral guide into contact with the side edge of the profile is the bending position.
  • a bending rail 30 lifts the profile up against the bending pins 22 for bending around them.
  • the automatic control likewise determines the displacement for effecting the required bend, upon which the bending rail returns to its initial position and the same applies to the lateral guide.
  • the profile is then fed on for effecting the next bend.
  • FIG. 5 An enlarged bending pin is shown in Fig. 5, where the side edge of the profile is guided in the groove 32 between the head 34 and the side wall of the lateral guide for stabilizing this during the bending process.
  • the machine is immediately capable of bending profiles of varying widths, just like it can bend profiles of limited height vaiation due to a certain latitude between the pins and the upper side of the bending rail.
