Definitions

  • the invention relates to a device for producing the beads and water seams by automatic winding or bending of the free overhanging, trimmed longitudinal edge areas of the blanks formed by deep drawing for one-piece gutter angles, the side walls of which are formed in a circular arc in the area of the corner connection of the abutting gutter angle pieces.
  • a gutter angle for connecting semicircular gutters is to be found in DE-U-78 11 514 provided, which is produced by deep-drawing sheet metal material and in which the side walls are each designed in the form of a circular arc in the region of their corners.
  • free edge areas remain on the longitudinal edges, which, after appropriate trimming, are rolled into beads or water folds are folded.
  • the device of the type mentioned at the beginning comprises a lower tool and an upper tool, the lower tool consisting of a fixed lower part which is adapted to the outer profile of the blank and an adjacent one on the side of the water fold to be formed, raised / lowerable raised part.
  • the upper tool is formed by a liftable / lowerable upper mold part which is adapted to the inner profile of the blank and can be clamped to the lower molded part, in which a liftable / lowerable support beam is fitted in a recess on the side of the water fold to be formed.
  • a rotating winding rod provided with a longitudinal slit, which can be pushed onto the edges of the free longitudinal edge regions, and which can be moved longitudinally and transversely.
  • a longitudinally displaceable, rotatable bending rod provided with a longitudinal slot and slidable onto the edges of the free longitudinal edge regions.
  • the raised part and the support beam each consist of two components that can be lifted / lowered in the corners.
  • a lifting / lowering support jaw is arranged for clamping the free longitudinal edge areas, each of which has a U-shaped recess running parallel to the axis of the blank, so that in the clamped position there is a channel between the two support jaws, into which the winding bars can be inserted and pushed onto the longitudinal edge areas.
  • the lower and the upper molded part are interchangeable, so that an adaptation to different profiles of the blanks for gutter angles is possible.
  • the winding rods and the bending rods are arranged on their longitudinal slides together with their drives, and the longitudinal slides for the winding rods are arranged on cross slides, the cross slides being movable on a track inclined towards the lower molded part.
  • the molded part 8 which forms part of the upper tool and can be raised / lowered with the aid of the cylinder 7 and corresponds to the inner profile of the blank 1, is clamped against the lower molded part 5.
  • the support bar 10 which can be raised / lowered via the cylinder 9 and forms the other part of the upper tool, is then lowered into the recess 11 of the molded part 8 located on the side of the forming water fold and then that on the side of the water fold to be formed next to the lower molded part 5 located, can be raised / lowered by the cylinder 12, raised form part 13, whereby the longitudinal edge regions 3, 3 'provided for the water rebate formation are placed approximately parallel to the vertical central plane of the blank 1.
  • the blank 27, which is formed by deep drawing and is trimmed on its longitudinal edges and is used to produce an inside gutter angle, the free longitudinal edge regions 28, 28 ', 29, 29' of which project approximately horizontally with respect to the vertical central plane, is arranged in a stationary manner in the base plate 30 lower molded part 31 of the multi-part lower tool, the profile of which corresponds to the outer profile of the blank 27, inserted and clamped against the lower molded part 31 by means of the molded part 33, which forms part of the upper tool and can be raised / lowered by the cylinder 32 and corresponds to the internal profile of the blank 27 .
  • the raisable / lowerable two support beam parts 35, 35 ' which form the other part of the upper tool and which are arranged on the side of the water fold to be formed, are lowered into the recess 36 of the molded part 33 via the cylinders 34, 34'.
  • the cylinders 37, 37 ' are used to raise and lower the two raised positioning parts 38, 38' one after the other on the side of the water fold to be formed next to the lower mold part 31 and forming part of the lower tool, so that the free longitudinal edge regions 28, 28 'of the blank 27 are formed approximately parallel to the vertical central plane so that they overlap in the corner area.
  • the winding bars 48, 48 ' are rotated by the drives 49, 49' and the bending bar 47 by the drive 50, whereby the beads 51, 51 'and a water fold 52 are formed.
  • the winding bars 48, 48 ' which are each located on a cross slide 53, 53', are moved towards the gutter angle on an inclined plane.
  • the second water fold 52 ' is then bent by the bending bar 47' to form an overlap in the corner area.
  • the molded parts 33, 35, 35 ', 41' forming the upper tool and the cylinders 32, 34, 34 'required for their actuation are fastened to the holding plate 55 attached to the cross member 54.
