Definitions

  • the invention relates to a device for deburring the end faces of rod-shaped workpieces, such as profile pipes or the like.
  • a machine bed on which a fixed and a movable machine unit are arranged, each of which carries a roller brush arranged transversely to the direction of travel and one made of a chain and attached carriers have existing, transversely to the direction of travel attached to each machine unit, the rotating roller brushes deburring the pipe profiles stored on height-adjustable roller bars between the machine units at the end as they are transported past, while hold-down brushes arranged above the roller bars load the tube profiles.
  • roller brushes Vertical adjustment of the roller brushes is necessary on the one hand, since depending on the vertical position of the roller brush relative to a profile, external deburring, internal and external deburring or internal deburring of a profile is possible. In addition, vertical adjustment is also necessary to adapt to different profile diameters.
  • roller brushes are also not easy to handle, since at least the roller brush on the movable loose side is very difficult for the machine operator to reach due to the feeding devices for the profiles he also finds only unfavorable working conditions in this area.
  • the separate vertical adjustment also complicates the possibility of automatic workpiece height adjustment and requires a very high level of technical effort
  • roller brush bearing must be designed very solidly so that it is able to absorb the vibrations emanating from the roller brushes rotating at high rotational speed.
  • a height adjustment of the roller brushes is also disadvantageous, since the brush bearings and the corresponding mechanisms of the height adjustment are in the area of heaviest contamination by the deburring dust and therefore have to be cleaned and serviced very often.
  • the object of the invention is to provide a device that is easy to manufacture and operate and that automatically ensures that both end faces of a tubular profile are automatically deburred regardless of the operator's qualifications.
  • the device according to the invention has the essential advantage that a parallel adjustment is always ensured with the help of the compulsory adjustment of the unrolling bars, so that the one defined by the unrolling bars is always in the balance.
  • This not only has an advantageous effect on the deburring success and the workpiece height adjustment, but the type of adjustment of the deburring machine according to the invention is much easier to handle and use, since it can follow from the fixed side, and can be automated in an advantageous manner.
  • this type of simultaneous adjustment of the fixed side and the loose side has the mechanical advantage that the bearing arrangement of the roller brushes in the two machine units can be made much easier, since the bearing support can now be firmly connected to the surrounding frame on both sides of the individual roller brushes.
  • the hold-down brushes are also simultaneously height-adjustable via the common drive.
  • This device according to the invention has the advantage that further manual manipulations on the fixed and loose sides can thereby be omitted, the automation of the machine is possible and the constant quality of the deburring of both workpiece end faces is ensured.
  • the drive is connected to a shaft which runs in the direction of travel and connects both machine units and which acts on at least one threaded spindle per machine unit, the height-adjustable sleeve of which is at least indirectly attached to the unwinding bar.
  • the invention also includes a drive with a shaft extending in the direction of travel, connecting the two machine units, which acts on each machine unit on at least one drive nut rotatably mounted in a housing, in which a height-adjustable trapezoidal spindle is arranged, which carries the rolling bar.
  • the drive torque in each machine unit is advantageously transmitted from the splined shaft to the drive nut via an angular gear drive and to at least one further, spaced drive nut via a sprocket disk arranged thereon.
  • the shaft is designed there as a splined shaft.
  • a device for deburring the end faces of rod-shaped workpieces is generally designated by the reference number 10.
  • the device 10 has a machine bed 11, which consists of two bases 12 and two travel rails 13.
  • a fixed machine unit 14 and a movable machine unit 15 are arranged on the machine bed 11.
  • Both machine units 14 and 15 each have roller brushes 16 arranged transversely to a direction of travel x.
  • each machine unit 14 or 15 is each provided with a transport device 17, which are driven together and each consist of a chain 18 with drivers 19 arranged thereon.
  • a hold-down brush N arranged on the fixed machine unit 14 can be seen above the transport device 17.
  • a so-called rolling bar 20 is arranged between a roller brush 16 and the transport device 17. Via a feed device, not shown, tube profiles 21 are fed to the transport device 17, gripped by the drivers 19 and moved along the roller brushes 16 with a simultaneous rolling movement on the rolling bars 20. End faces 22 are deburred by the roller brushes 16 made of special wires.
  • roller brushes 16 move in opposite directions, while the tubular profiles 21 are rolled past the roller brushes 16 in the y-direction on the rolling bars 20, with hold-down brushes on the roller brushes in a manner not shown in FIG. 2 Act tube profiles 21.
  • FIG. 3 shows a height adjustment 23 of a rolling bar 20 with the aid of a threaded spindle 24.
  • a shaft 26 connecting both machine units 14 and 15 is driven, which is formed in the area of the machine unit 14 as a cylindrical shaft 26 a and in the area of the machine unit 15 as a splined shaft 26 b.
  • the drive torque is from the shaft 26 in the area of each machine unit 14 and 15 via an angular gear 27 to a sprocket 28.
  • the bevel gear 27 is formed by two bevel gears K 1 and K 2 .
  • the bevel gear K 1 is arranged on the cylindrical shaft 26 a by means of a clamping sleeve S, while the bevel gear K 2 is mounted on a shaft W arranged perpendicular to the shaft 26, which also carries the chain wheel 28.
  • the drive torque is transmitted from the sprocket 28 via a further sprocket 29, which is arranged on the threaded spindle 24, to a sleeve 30 of the threaded spindle 24, which is connected to a rolling bar 20 via a support arm 31.
  • each rolling bar 20 takes place via two spaced height adjustments 23, each provided with a threaded spindle 24, which are driven by means of a common drive chain k via the chain wheel 28.
  • the movable machine unit 15 has two devices 23 described above.
  • the bevel gear K 1 is not supported with a clamping bush S on the splined shaft 26 b, but on the housing side, so that the machine unit 15 can be fully moved in the direction of travel x.
  • the transport device is only an example on the fixed side (machine unit 14) 17 with its associated parts (see FIG. 2), the unrolling bar 20 and a hold-down brush 32 arranged at a certain distance above the unrolling bar 20, by means of which a controlled unrolling of the tubular profiles 21 on the unrolling bars 20 is made possible.
  • FIG. 5 shows a further height adjustment 33, in which, starting from a drive motor 25 and a shaft 26 with a cylindrical shaft section 26 a and a shaft section 26 b designed as a splined shaft, a torque is transmitted to the angular gear transmission 27.
  • the bevel gear mechanism 27 is directly connected to a drive nut 34 which is rotatably arranged in a bearing housing 36 via ball bearings 35.
  • a trapezoidal spindle 37 is also rotatably mounted, which carries 38 fastening elements 39 for the rolling bar 20 at its upper end 38 which protrudes out of the drive nut 34.
  • the drive nut 34 is horizontal mounted sprocket 40 connected to a further height adjustment 33, not shown.
  • This type of forced height adjustment of the two rolling bars 20 ensures in every position that the E formed by the rolling bars 20 is always in the balance.
  • a similar guide component 42 which is arranged in the construction of the machine unit 15, serves for the rotatable mounting of the bevel gear K 1 engaging in the splined shaft 26 b, which in turn meshes with a bevel gear K 2 arranged on the drive nut 34.
  • This arrangement similar to the embodiment according to FIG. 3, gives the machine unit 15 full mobility.
