Definitions

  • the invention relates to a method for bending a profile bar made of metal, in particular aluminum, the profile of which has at least one profile leg transversely to the bending plane, the profile bar being guided between at least three bending rollers arranged at an adjustable distance from one another, of which the middle bending roller relates to the profile bar two is opposite outer bending rollers, and wherein at least the one transverse to the bending plane profile leg of the profile rod is guided relative to the central bending roller by means of a guide element.
  • the profile leg of a profile rod which is located in the bending direction, is supported in a tensile zone on its inside facing the bending axis by guide rollers, whereas the profile leg, which presses against the middle bending roller, is pressed on - Its outside does not receive any support, which can lead to undesirable deformations in this pressure zone.
  • the area of the profile rod between the outer and the inner profile leg is not supported so as not to impede the rotation of the guide rollers, so that there is also a risk of deformation in this area, in particular with small bending radii and complicated profile cross sections.
  • the object of the invention is to provide a method for bending a profile bar made of metal, in particular aluminum, which allows the bending of profile bars with a comparatively complicated profile without undesired deformation of the profile shape and allows small bending radii.
  • the profile shape of the guide element is complementarily adapted to the profile shape of the profile rod on its side carrying the profile leg, and in that the profile rod is guided between the guide element and a support disk of the middle bending roller leading the profile rod on the side facing the guide element.
  • the profile is supported on both sides by the guide element and the central bending roller and thus the support disk, and an inadmissible deformation of the profile is thereby prevented.
  • roller 1 consists of the two outer rollers 1 and the middle roller 3. Both the distance of the two rollers 1 and 2 from each other and the distance of the axis 6 or roller 3 from which the axes 4, 5 of the straight lines connecting rollers 1, 2 are adjustable. If a workpiece or a profile rod 7 is now introduced in the direction X into the opening between a complementarily adapted (profile-specific) guide element 10 and support disks of the roller 3, respectively. pushed between the support disks of rollers 1, 2 and then moved in the direction of arrows X, its radius of curvature is reduced. If this operation is repeated several times, the roller 3 being displaced in the direction of the arrow Y after each passage of the workpiece 7, the radius of curvature is further reduced.
  • FIG. 2 illustrates the device with the angular support 8, which is firmly connected to a slide on which the deliverable roller 3 and the rigid bracket 9 sit, which serve as supports for the profile-specific guide element 10.
  • the workpiece 7 is guided between the guide element 10 and support disks of the roller 3, the guide element 10 being able to be prestressed in the Y direction by means of locking screws in slots 11 with the feed screw 12.
  • Fig. 3 is a sectional view of the device with a different type of workpiece or a profile rod 13 is shown. Without the complementary (profile-specific) guide element 14 adapted to the profile rod 13, the wall on the outside of the arch would be pulled inwards during bending.
  • the method according to the invention is the adaptation of the guide elements in shape and material to the respective profile shapes and materials.
  • the method allows workpieces of relatively large width or rather high free-standing walls, respectively. to bend with free-standing formations into arches or rings and to carry out the bending process continuously.
  • the device can be attached to any suitable bend resp.
  • Rolling machine can be attached.
