  • a sheet rolling machine of this kind is from the EP 1 213 063 A have become known to the applicant.
  • the working head is designed as a turntable and has three beading tools, which are each by a hand lever on and disengaged.
  • the invention has for its object to provide a sheet rolling machine of the type mentioned, which is even less expensive to produce and also easier to use.
  • a central compressed air supply is provided, which is connectable to said drive means for introducing the bead depth.
  • the compressed air supply is provided with connecting means which are switched on and disengaged.
  • Sheet metal rolling machine 1 shown has a machine frame 37 which is provided with a base plate 38 on a building floor and which is provided with wheels 28 for adjusting the sheet rolling machine 1.
  • a machining head 2 Arranged at the upper end of the machine frame 37 is a machining head 2 which, as can be seen, projects radially and which has a lower and a fixed bearing block 8 with a lower bead roll 23 and an upper pivotable bearing block 7 with an upper bead roll 24.
  • the two bead rolls 23 and 24 are connected via a lower bead shaft 10 and upper bead shaft 9 with a drive 3, which has an upwardly projecting drive shaft 4 and a gear unit 29.
  • the drive shaft 4 is driven in particular by a motor.
  • the gear unit 29 has a bevel gear pair 5, with which the lower bead shaft 10 is driven. About a Stirnradpar 6, the rotational movement of the lower bead shaft 10 is transmitted to the upper bead shaft 9.
  • the two bead shafts 9 and 10 are parallel to each other and the directions of rotation and the rotational speeds are the same. The direction of rotation can be changed according to double arrow B.
  • the upper bearing block 7 is limited pivotable about a horizontal axis of rotation 20. As can be seen, this axis of rotation 20 is arranged at the rear end of the upper bearing block 7.
  • the bearing block 7 can also be adjusted horizontally limited by means of a pivot lever 19 and an eccentric, not shown here in the directions of the double arrow X.
  • the comparatively small adjustment range is for example 2 mm. By means of a clamping lever 21, this adjustment can be fixed.
  • This horizontal adjustment of the upper bearing block 7 is made possible by the pair of spur gears 6, which meshes within the adjustment range.
  • a stop plate 25 is mounted with a guide rod 18, the horizontally in the directions of the arrow V according to an adjustment handle 16 FIG. 2 is adjustable.
  • the dimension b indicates the distance of the inside of the upper bead roll 24 to the guide surface of the stop plate 25.
  • a clamping lever 17 By means of a clamping lever 17, a set dimension b can be fixed.
  • the stop plate 25 serves to guide a sheet to be processed 26. For processing, the sheet 26 is passed in the directions of the double arrow Z between the bead rollers 23 and 24 and thereby the in FIG. 3 shown bead S incorporated.
  • the desired depth of the bead is achieved, as for example in FIG. 3 indicated at a machined plate 26a.
  • the two bead rollers 23 and 24 are each releasably attached to the bead shaft 10 and 9 and can be replaced.
  • other working means for processing metal sheets are also possible here, which are stored in a tool box 27.
  • a drive A is arranged on the machine frame 37, which has an air pressure cylinder 14 which can be actuated via a switch, not shown here, for example via an electric foot switch.
  • a piston rod 39 of the air cylinder 14 is articulated to a rear fork-shaped end of a lever 11. If the compressed air cylinder 14 is actuated at the said switch, then the piston rod 39 moves upwards until a rotary part 41 mounted on the lever 11 engages on a hand crank 13. The hand crank 13 thus limits the possible pivoting movement of the lever 11 and thus forms a stop. If the lever 11 as mentioned pivoted so moves a nose 11a of the lever 11 down and pivoted according to the upper bearing block 7 about the rotation axis 20.
  • the upper bead roll 24 in the direction of the double arrow Y against the retroactive force of a spring element 15 vertically downwards against the lower bead 23 moves.
  • the hand crank 13 is rotated clockwise. Since the nut 22 preferably has a left-hand thread, thereby the hand crank 13 is moved upward. With the air cylinder 14 so that the lever 11 can be pivoted again by a certain amount, so that the nose 11 a, the upper bearing block 7 moves further down.
  • the depth of the bead can thus be increased by appropriate stepwise rotation of the hand crank 13 in a clockwise direction, until finally the intended bead depths and thus the bead S is reached.
  • the hand crank 13 If the hand crank 13 is rotated counterclockwise, the hand crank 13 is moved downward. The bead depth is thus reduced accordingly.
  • the position of the hand crank 13 can be indicated by a scale, not shown here, or other suitable means.
  • the hand crank 13 thus forms a stop. It can also be replaced by other suitable means, and means are also conceivable that allow remote operation.
  • the hand crank 13 could be rotated by an electric motor.
  • the air cylinder 14 thus forms with the lever 11, the drive A for introducing the bead depth.
  • the air cylinder 14 could also be replaced by other suitable drive means.
  • a compressed air line 42 which leads to the compressed air cylinder 14 is in FIG. 1 merely hinted.
  • a machine frame 37 ' here is solid and has at least one extendable wheel 30 which, together with the wheels 28, enables a method of the sheet metal rolling machine 1'.
  • a turntable 40 is mounted, which has three processing heads 2a, 2b and 2c, which are symmetrically arranged as shown and formed substantially the same.
  • the two corrugation shafts 9 and 10 shown in the machining head 2a, the lever 11, the pneumatic cylinder 14 and the lever 19 and other parts explained above are thus also provided in the machining head 2b and in the machining head 2c.
  • the turntable 40 is rotatable about a vertical axis 43 which extends in the drive shaft 4.
  • the sheet rolling machine 1 ' is provided for a fixed working position, to each of which the desired machining head 2a, 2b or 2c is brought.
  • the bead rollers 23 'and 24' arranged at the machining head 2b are as a rule different from the bead rollers 23 and 24 and this also applies to the bead rollers of the working head 2c, not shown here.
  • These bead rolls can be exchanged, including a tool box 27 is provided in the machine frame 37 '. If the working position is provided at the machining head 2b and the bead rollers 23 and 24 are required for machining the sheet 26, the turntable 40 is rotated counterclockwise by 120 °, so that now the machining head 2a is in the earlier position of the machining head 2b. With a clockwise rotation of 120 °, the machining head 2c can be pivoted to the working position.
  • the bevel gear pair 5 must be decoupled.
  • a compressed air cylinder 35 is provided, with which a wedge 36 is horizontally displaceable and thus the bevel gear 5 connected to the shaft 4 can be lowered until it is no longer engaged with the bevel gear attached to the lower bead shaft 10. If the wedge 36 is displaced in the opposite direction, the bevel gear 5, which is displaceably mounted on the shaft 4, moves upwards and thus engages with the other bevel gear.
  • the rotary bearing for the turntable 40 is in FIG. 4 indicated by the reference numeral 34.
  • Such a pivot bearing for the axial and radial guidance of the turntable 40 may be formed in a conventional manner.
  • the compressed air line to the turntable 40 and thus to the compressed air cylinder 35 and the corresponding compressed air cylinder 14 is also interrupted.
  • a compressed air cylinder 33 and an index pin 32 are provided, which are mounted below the turntable 40 at the machine position 37 '.
  • the compressed air cylinder 33 can be actuated via a line not shown here with the foot switch 31.
  • the index pin 32 moves up or down in the directions of the double arrow W. If the index pin 32 is moved down, the compressed air connection to the turntable 40 is interrupted and this can be freely rotated in both directions after decoupling the gear unit 29.
  • the index pin 32 on the foot switch 31 is moved upward, so that now the compressed air cylinders 35 and 14 are supplied with compressed air.
  • the corresponding compressed air lines to the compressed air cylinders 35 and 14 are not shown in the figure. If the compressed air cylinder 35 is supplied with compressed air, the gear unit 29 can be coupled accordingly by displacing the wedge 36 become.
  • the lines in the turntable 40 are arranged so that only the air cylinder 14 is supplied with compressed air, which belongs to the processing head 2a, 2b and 2c, which is in the working position. The other two compressed air cylinder 14 are not supplied with compressed air. In the in FIG.
  • the air cylinder 14 of the processing head 2b is supplied with air pressure.
  • the air cylinder 14 of the two processing heads 2a and 2c are not supplied with compressed air, so that with a corresponding actuation only at the two bead rolls 23 'and 24', the corresponding depth of the bead can be introduced. This is also advantageous for safety reasons, since the unneeded seepage rollers do not turn.
  • the gear unit 29 In the home position, the gear unit 29 is disengaged and the index pin 32 is in a lower position.
  • the turntable 40 is now rotated until the desired machining head 2a, 2b and 2c, respectively, is in the desired working position. Is, for example, according to FIG. 4 the machining head 2b after a corresponding rotation of the turntable 40 in the working position, the indexing pin 32 is moved upwards by actuation of the foot switch 31.
