Definitions

  • the invention relates to a device for folding the edges of roof cutouts for sunroofs of motor vehicle bodies, the body having an outer panel and an inner panel, each with an upstanding flange that delimits the roof opening, and wherein the flange of the outer panel is wider than the flange of the inner panel.
  • the outer panel of the body is connected to the inner panel in that the flange section of the outer panel projecting over the upstanding flange of the inner panel is folded over the flange of the inner panel.
  • two work steps are required, the folding by 90 ° and the subsequent folding, which in practice are carried out with different devices or, if necessary, by hand. This requires extensive manipulations of the body panel.
  • flanging methods and corresponding flanging devices for pre-flanging and finished flanging of body parts wherein a radially movable slide is provided on a press tool for producing a flanging, the pre-flanging edge for carrying out the subsequent finished flanging is movable outwards.
  • the parts are pre-flanged in a first forming phase of the press tool by means of a pre-flanging edge of a movable slide and subsequently the slide moves radially outwards and in a second shaping phase of the press tool, a second flanging tool with a flanged edge finishes the parts to be connected.
  • the object of the invention is to carry out the folding by 90 ° and the subsequent folding of the edges of roof openings for sunroofs in one device.
  • a folding bed as a support for the outer sheet and the inner sheet arranged thereon
  • folding slide part of which can be displaced both parallel to the plane of the roof cutout and orthogonally to it and each have folding strips for gripping and folding the section of the flange of the outer plate projecting beyond the flange of the inner plate.
  • the outer sheet which has an upstanding flange that delimits the roof cutout, is placed on the folding bed.
  • the inner sheet which also has a raised edge, is placed on top of it.
  • the flange of the outer sheet is supported in the abutment.
  • the flange of the inner sheet is pressed against the flange of the outer sheet and thus against the abutment - -
  • folding slide parts are adjusted so that the undersides of their folding strips are essentially aligned with the upper edge of the flange of the inner plate and the thickness of the outer plate, and the folding slide parts are moved such that the one projecting over the flange of the inner plate
  • Flange section of the outer sheet is first folded by approximately 90 ° over the upper edge of the flange of the inner sheet.
  • the filling slide is then removed or moved in such a way that the folding slide parts can be moved parallel to the upstanding flange of the inner sheet and the protruding ones already folded by 90 °
  • the folding bed has a recess corresponding to the roof cutout and is arranged in the recess of the ring-shaped abutment.
  • the abutment is displaceable in the recess orthogonal to the plane of the roof cutout.
  • the filling slide can also be made in several parts, the filling slide parts being displaceable essentially parallel to the plane of the roof cutout.
  • a version is recommended in which the filling slide parts are arranged along the straight edges of the roof cutout and can be moved in the direction of the roof cutout. Otherwise, the filling slide parts are arranged along the straight edges of the roof cutout and can be moved in the direction of the roof cutout. Otherwise, the filling slide parts are arranged along the straight edges of the roof cutout and can be moved in the direction of the roof cutout. Otherwise, the
  • Filling slide parts extend along the straight edges into the corner areas of the roof cutout and have, at least in some areas, side faces which are arranged at an angle of 45 °. This ensures that the flanges of the outer sheet and inner sheet are sufficiently held in the corner areas between the abutment and the filler slide parts.
  • the filling slide parts In order for the first folding process, namely the folding of the protruding flange section of the outer sheet to proceed in a defined manner by approximately 90 °, it is advantageous if the filling slide parts have an edge strip on the roof cutout side as a folding counter bearing for the folding strips of the folding slide parts. These edge strips are removed together with the filler slide parts before the start of the second folding process.
  • the folding slide parts are arranged in the area and above the recess.
  • the folding slider includes, on the one hand, folding slider parts that extend along the straight sections of the roof cutout and can be moved in the direction of the roof cutout, and on the other hand, folding slider parts that are assigned to the corner areas of the roof cutout and at an angle of approx. 45 ° to the straight ones Edges of the roof cutouts can be moved. So that the filling slide parts on the one hand and / or the folding slide parts on the other hand do not interfere with one another during the folding operations, the filling slide parts and / or the folding slide parts should be able to be displaced independently of one another at least parallel to the plane of the roof cutout. It goes without saying that the filling slide parts and the folding slide parts are assigned corresponding drives.

  • the device includes a folded bed 5 as a support for the outer sheet 1 and the inner sheet 3 arranged thereon.
  • the folded bed 5 has a recess 6 corresponding to the roof cutout, in which an annular abutment 8 movable in the direction of arrow 7 with a drive (not shown) is arranged for the flange 2 of the outer plate 1 and the flange 4 of the inner plate 3 resting thereon.

  • the filler slide parts 9 extend along the straight edges of the roof cutout into the corner areas of the roof cutout and end on side surfaces 11 which extend at an angle of approximately 45 °, so that the flanges 2 and 4 also between the corner areas of the roof cutout the filling slide parts 9 and the abutment 8 are held or clamped.
  • the filling slide parts 9 also have an edge strip 12 on the roof cutout side, the upper side 13 of which has the upper edge of the flange 4 of the inner plate 3 is aligned, so that this top 13 forms a folding counter bearing.

  • the filling slide parts 9 are moved back in the direction of the arrow 10, in the illustrated embodiment by about the width of the folding strips 19. Then the folding slide parts 14 are moved downwards in the direction of the arrow 18, whereby they protrude Fold flange sections 20 of outer panel 1 tightly around flange 4 of inner panel 3.
