Definitions

  • the invention relates to a sheet metal rolling machine according to the preamble of claim 1.
  • a sheet metal rolling machine for flanging thin sheets is e.g. known from US-A-4,726,107.
  • Beading and flanging are well-known processes on thin sheets. In both cases, machines with an identical basic structure are used. Two cooperating and driven rollers, which depending on their shape and their mutual orientation, in one case the edge of a sheet metal strip, give either a bead shape or in the other case a flanged shape, whereby a single sheet metal part usually only has one or the other shape. In many cases, beading rollers and / or flanging rollers can be removed and installed as quick-change kits on corresponding sheet metal rolling machines. In the case of round machines, beads can be attached to both sides of a corresponding tube shape at the same time as the rolling process.
  • the object of the invention was now to improve sheet metal rolling machines so that adjustments can be made quickly and easily with the greatest possible stability of the machine and the flanging and beading work can be carried out economically for a majority of the cases.
  • a work roll is mounted on a yoke, which has the shape of a torsion-resistant, rigid, U-shaped body, enables the roll stand to be designed with comparatively small dimensions and great stability; the precision of the work result and the rapid adjustability of the machine are correspondingly high.
  • the invention allows a number of particularly advantageous configurations, for example a pair of work rolls projecting from both sides of the yoke, the yoke bearings can be arranged parallel to the work roll bearing on one side of the work rolls and the adjusting means on the opposite side of the work rolls.
  • the roller stand with the work rollers is preferably designed to be rotatable about an axis. This allows various work processes to be carried out efficiently on the same machine with only a minimal changeover time, especially if it has two units with the same axis of rotation, each with a set of flanging rollers or beading rollers, which can be set against each other.
  • the bead rolls or flanging rolls can be switched from a horizontal to a vertical working axis and, in one case, for example, an opposite bead on both sides, and in the other case the sheet edges accordingly.
  • At least one unit can preferably be displaced on a longitudinal rail in order to adjust the working distance of the beading rolls or flanging rolls.
  • FIG. 1 represents an entire roller stand 1 with attached drive motor 2 and adjusting means 3 in perspective.
  • the roller stand 1 has a fixed bearing block 4 and a U-shaped yoke 5, in each of which the work rolls of two pairs of work rolls 6, 6 'and 7, 7' are mounted.
  • the two pairs of working rollers are a pair of beads 7, 7 'and a pair of flanges 6, 6' and have a movable axis 9 in the crosspiece of the yoke 5 and a fixed axis 8 in common.
  • the beading roller 7 and the flanging roller 6 are mounted on the same shaft 10 which is coaxial with the axis 8 and which is rotatably mounted in the fixed bearing block 4.
  • the bead roller 7 'and the flanging roller 6' are mounted on a shaft 11 which is coaxial with the axis 9 and which is rotatably mounted in the yoke 5.
  • the yoke 5 is pivotally mounted on the fixed bearing block 4 with its legs on a pivot pin 12 parallel to the axes 8 and 9.
  • a tension rod 13 is connected to the yoke 5 with a bent leg 13 ′, which is approximately parallel to a plane, formed by the axes 8 and 9, in front of the roller stand 1.
  • a pressure piston cylinder 14 is articulated via its piston rod 15 and a tab 16 to a pivot pin 17 arranged on the cantilever part 13 ′′. Furthermore, the pressure piston cylinder 14 is firmly supported by means of a retaining bolt 19 in a side plate 20 fastened to the fixed bearing block 4. In the side plate 20, a shaft 21 is also rotatably mounted, on which an eccentric 22 and an adjusting lever 23 is attached. With the structure shown, there are now two opposing forces. The pressure in the pressure piston cylinder 14, via the piston rod 15, causes a downward pressure force in the position shown, according to arrow 24, which causes the distance X between the axes 8 and 9 to be reduced.
  • the adjusting lever 23 is preferably provided with a setting scale (not shown) so that an earlier value can be reset at any time.
  • a remotely controllable adjustment drive for example an electric eccentric adjustment, can also be used instead of the manually operated adjustment lever 23.
  • Both roller stands 1, 1 'each have opposite pairs of beading rollers 7, 7' or flanging rollers 6, 6 ', in Figure 2 the two beading roller pairs 7, 7' are in use for the simultaneous beading of a sheet 29, for which the Roller stands 1, 1 'are set to a working distance L.
  • a bead 30 formed in the process is shown enlarged in FIG. 6B.
  • FIGS. 3 and 4 show how the roller stand 1 is connected to the drive motor 2 via a turntable 31, the turntable 31 being held in a plurality of guide rollers 32 which are arranged on an upright cheek 33 of a sliding table 34.
  • the sliding table 34 has a slide 35 which can be moved horizontally together with the roller stand 1.
  • a reversing drive 36 which is designed, for example, as a simple pneumatic or hydraulic cylinder and is articulated on the sliding table 34, can now turn the entire roller stand 1 together with the drive motor 2 through an angle of approximately 90 ° (FIG. 5) without the motor Drive interrupted or the distance between the work rolls is changed.
  • the drive motor is via a flange 37 2 rigidly connected to the fixed bearing block 4 by screws 38.
  • a drive bevel gear 40 Arranged on a drive shaft 39 is a drive bevel gear 40 which, via an overdrive bevel gear 41, drives a shaft 42 arranged at right angles to the drive shaft 39 and a gear 43 rigidly wedged thereon.
  • An overdrive spur gear 44 and a gear 45 mesh with the gear 43.
  • a gear 46 also meshes with the overdrive gear 44.
  • the gear wheels 45 and 46 are each connected in a rotationally fixed manner to one of the shafts 10, 11 and drive the pairs of work rollers 6, 6 'and 7, 7'.
  • the whole gear set has a double reduction.
  • the two roller stands 1, 1 ' are turned by the turning drive 36 by about 90 ° or by an angle ⁇ , so that the flanging rollers 6, 6' are in use in this position.
  • the two roller stands 1, 1' are also set at the desired distance L in FIG. 5 for flaring, so that the sheet 29 is in turn machined on both sides simultaneously can.
  • the fold is closed with the flanging rollers 6, 6 'on the sheet metal sides facing away from one another.
  • Two sheet metal parts, namely the sheet 29 and a side sheet 47 are closed to form an essentially tight connection. Before the sheet metal parts are closed, several operations are required.
  • the side part 47 must first be provided with a side fold 48 according to FIG. 6A. Thereafter, the beads 30 are pressed in on the sheet 29 on both sides, possibly via two to three depth settings, as shown in FIG. 6B.
  • FIG. 5 shows a further combination with a stapling device 49, which is actuated by a pressure cylinder 50, a stapling pliers 51.
  • the stapling device 49 is attached directly to the machine stand 28, so that the work sequence is possible with the shortest possible travel distance.
  • the attachment of the stitching points is shown on a larger scale in FIGS. 6C and 6D.
  • the subsequent closing of the fold is shown in FIG. 6E.
  • both pairs of work rolls can each be mounted in a pivotable yoke 5 via pivot pins 12 with a correspondingly designed fixed bearing block 4, the setting means 3 being able to be designed essentially in accordance with FIG.
