Definitions

  • This invention relates to an edging machine for folding up a flange along opposite edges of a sheet metal panel as defined in the preamble of the claim.
  • FR-A-2 080 634 discloses a machine of this kind which is designed to fold up z-shaped flanges along the longitudinal edges of a pair of elongated flat metal sheets from which rectangular metal ducts are then formed. Although this machine is meant to be portable, it is rather heavy and bulky.
  • An object of the present invention is to provide an edging machine for forming upstanding flanges on sheet metal roof panels which is of compact and lightweight construction so that the roofer can readily take the machine with him to the building to be provided with sheet metal roofing.
  • the edging machine of the invention as defined in the preamble of the claim embodies the features set forth in the characterising part of the claim.
  • the machine comprises two sets of aligned pairs of rotatable forming rolls. These sets are disposed along respective longitudinal edges of a horizontal panel feed table.
  • Each pair of forming rolls comprises an upper forming roll and a lower forming roll.
  • the axes of rotation of all forming rolls of the set or each set are parallel and contained in vertically spaced planes including an acute angle with the feed table. Thanks to the inclined axes, the forming rolls may have relatively small dimensions so that the entire machine, or at leastthe part of the machine comprising the set or sets of forming roll pairs, can be compact and lightweight.
  • the edging machine is used for simultaneous forming of initially flat sheet metal roof panels into the cross-sectional shape shown in FIG. 3.
  • the finished flanged panels comprise a flat intermediate portion A, an "outer” flange b and an “inner” flange C (theterms “inner” and “outer” as used herein refer to the relative positions of the abutting flanges of contiguous panels laid on the supporting structure).
  • the machine shown in the drawings comprises a horizontal panel feed table 10 defining a horizontal panel feed plane 10A.
  • the feed table 10 comprises an infeed section 11 formed of a flat plate having parallel lateral guides 12 and 13 adjustably spaced apart by a distance corresponding to the width of the sheet metal panel to be formed with flanges.
  • the feed table also comprises an edging section 14 including a number of horizontal bars 14A mounted on a frame 15. Two of the bars 14A extend in the feed direction past the frame 15 to provide support for the flanged panel as it leaves the edging section 14.
  • Two sets 16 and 17 of pairs of forming rolls are supported on the frame 15 along respective longitudinal sides of the edging section 14.
  • the set 16 comprises six pairs 18 of forming rolls serving to form the "outer" flange B, while the set 17 comprises four pairs 19 serving to form "inner” flange C.
  • Each pair 18, 19 comprises an upper and a lower forming roll 18A, 188 and 19A, 19B, respectively, defining a nip for the panel margin approximately level with the feed plane 10A.
  • the rolls are secured to respective ones of a pair of parallel shafts 20, 21 which are rotatablyjounalled in a support 22,23 on the frame 15.
  • the axes of rotation of the two forming rolls 18A, 18B and 19A, 19B of each pair are parallel and contained in a common vertical plane extending transversely across the feed table 10.
  • the axes of rotation of the upper rolls 18A, 19A are contained in a common plane 24, 25, respectively, including an acute angle a with the feed plane 10A.
  • the axes of rotation of the lower rolls 18B, 19B of each set 16, 17, respectively, are contained in a common plane 26, 27 parallel to the plane 24, 25, respectively, of the axes of the upper rolls and thus including the same acute angle a with the feed plane 10A.
  • the parallel and vertically spaced planes 24, 26 intersect the parallel and vertically' spaced planes 25, 27 along horizontal lines below the feed plane 10A.
  • the angle a is 35°-55°, preferably about 45°.
  • the shaft 20 of this roller 18B is connected through universal joints 30 and a telescopic shaft 31 to the shaft 21 of the lower forming roll 19B of that pair 19 of the set 17 which is positioned at the infeed end of the edging section 14.
  • the other forming roll pairs are driven from the just-mentioned pairs through gear transmissions 32, 33.
