Definitions

  • the invention relates to a beading machine for the machining of sheet metal according to the preamble of claim 1.
  • Beading machines have long been known in the art. They deform a sheet between work rolls by progressively bending in an edge direction. Beads are used in particular for stiffening sheets or for joining nested parts.
  • the metal sheet, pipe or the like to be machined moves between two rollers that carry the profile of the bead during beading. Both rollers are driven and take the sheet metal.
  • By adjusting at least one bead of beading a beading tool or by replacing the beading tool different beads can be produced.
  • a beading machine which has two arranged on a common shaft beading tools. These beading tools can be set differently. Depending on the bead to be produced, one or the other tool is used.
  • US-A-4,487,048 discloses a machine for incorporating beads into box blanks. At the periphery of a common drive shaft bead stations are arranged, which are positively controlled. All bead stations work simultaneously.
  • the invention has for its object to provide a beading machine of the type mentioned, which allows an even more efficient and yet secure machining of sheet metal.
  • the invention is achieved in a generic beading machine according to claim 1.
  • the machining of a metal sheet with each of the beading tools is possible at a single working position.
  • the working position need not be left when changing to another beading tool.
  • the beading machine according to the invention can therefore be arranged, for example, in a corner of the room, and yet three or more beading tools can be present and optionally used. In three beading tools, these are preferably arranged in the corners of a triangle.
  • the turntable When changing the beading tool then then the turntable must be rotated only by 120 degrees in one or the other direction.
  • the beading tools may for example be bead rolls, which, however, are each set differently. Conceivable here are also different beading tools.
  • Each beading tool can be engaged and disengaged with a single common drive. For a simple construction is possible and also only the used beading tool is driven in each case, which is advantageous in terms of safety at work. When working stand so that each unused beading tools.
  • the beading machine 1 has, according to FIG. 1, a machine frame 2 which has three drives 3 at its lower end and is placed on a building floor 32.
  • the drives 3 each have on a holder 5 a height-adjustable roller 4.
  • the beading machine 1 can be parked on the floor 32 or moved in the raised state.
  • a drive unit 6 which has an electric motor 7 or another suitable motor, is arranged on the machine frame 2.
  • the drive axis A of this drive unit 6 extends vertically and centrally to a turntable 8, which according to FIG. 2 at equal distances from one another and peripherally has three bead units 9, 9 'and 9' '.
  • the turntable 8 is mounted rotatably about the axis A on the machine frame 2.
  • Fig. 2 shows with the double arrow 34, the directions of rotation in which the turntable 8 is indefinitely rotatable about the axis A.
  • the drive unit 6 has, according to FIG. 3, a bearing block 17 which is fixedly connected to the machine frame 2 and in which a bevel gear 35 is inserted.
  • This transmission 35 consists essentially of a bevel gear 14 which is fixedly connected to a vertical drive shaft 15 and three further Bevel gears 18, each of which is fixedly connected to a coupling shaft 16 and each mesh with the bevel gear 14.
  • Fig. 3 only one bevel gear 18 and two coupling shafts 16 are visible.
  • the three coupling shafts 16 are arranged in a star shape and the angle between adjacent coupling shafts 16 is 120 degrees.
  • embodiments are also conceivable in which only two coupling shafts or more than three coupling shafts 16 are provided.
  • the arrangement is here preferably symmetrical and all shafts 13 are driven together by the shaft 15.
  • the coupling shafts 16 project beyond the bearing block 17 with an outer end, as shown in FIG. 3.
  • a coupling piece 36 is mounted slidably limited.
  • a coupling lever 19 which is pivotally mounted at its upper end 19a to a block and at its lower free end has a latching handle 20, the coupling piece 36 can be adjusted in the directions of the double arrow 38 limited.
  • Each of the shafts 16 can be coupled by pivoting the coupling lever 19 with a corresponding positioning of the turntable 8 with one of the bead units 9, 9 'and 9''.
  • the coupling piece 36 is moved radially outward from the position shown in FIG.
  • clutch claws 28 engage between corresponding clutch claws 28 of a gear 27, which is fixedly connected to a shaft 25 of a bead rollers 21.
  • the wheel 27 meshes with a gear 26 which is connected to an upper shaft 24 of the upper bead roll 22.
  • the two bead rolls 21 and 22 are mounted in a bearing block 39, on which a stop plate 11 is mounted radially adjustable.
  • the stop plate 11 engages with a web 40 in a not shown here recess of the bearing block 39 and can in each position can be clamped by means of a clamping member 31.
  • the two bead rolls 21 and 22 pass through the stop plate 11.
  • a stop plate 11 is provided for each bead unit 9, 9 'or 9 ".
  • the two bead rollers 21 and 22 are formed as known per se. But it can also be provided here other beading tools.
  • a sheet 41 to be machined is brought together in a manner known per se between the running beads 21 and 22, as indicated in FIG. 5.
  • the sheet 21 may also be a pipe or a lid. This is processed, for example, according to FIG. 2 in the two-clock position with the bead unit 9. If now this sheet metal piece 41 or another piece of sheet metal with the bead unit 9 'to be processed, the bead unit 9 is disengaged and the turntable 8 is rotated counterclockwise by 120 degrees. The bead unit 9 'is now in the two-clock position. All bead units 9, 9 'and 9' 'are not driven.
  • the bead unit 9 ' is coupled to the drive unit 6 and the sheet 41 can also be machined in the two-clock position with the bead unit 9'. If the bead unit 9 'is no longer needed, it is decoupled and the turntable 8 can now be rotated either clockwise or counterclockwise. A rotation of the turntable 8 is only possible if all bead units 9, 9 'and 9' 'are decoupled. This ensures that only the bead unit 9, 9 'or 9' 'that is required for machining a metal sheet 41 is driven during machining.
