Definitions

  • the invention relates to a method for producing a metallic strip having at least two strips of different thickness running in the longitudinal direction of the strip, by means of rollers, between which the strip is made, thereby producing a strip of reduced thickness by means of a rolling process.
  • the invention further relates to a device for producing a metallic strip having at least two strips of different thickness running lengthwise of the strip, with rollers between which the strip is made producing at least one strip of reduced thickness by rolling, and a drive for conveying of the tape through the rollers.
  • Such a method and such a device are known for example from DE 101 56 087 A1.
  • the band is formed during forming both in length and in width. While forming in width is desirable in these instances, the proportion of forming in length poses significant problems, since the larger gauge strip which is not or less formed undergoes no or less elongation than the more formed strip, which leads to distortions or to a corrugation of the band, so that the band then has to be evenly smoothed or straightened.
  • the invention is therefore based on the object to provide a method and an apparatus in which there are fewer distortions or undulations.
  • This object is achieved in a method of the type mentioned above in that mounted on a planetary work rolls are moved during the rolling process in the direction of conveyance of the belt opposite direction.
  • this object is achieved in that a planetary gear, are mounted on the work rolls, a direction of rotation, which is opposite to the conveying direction of the tape.
  • the at least one strip is rolled with a planetary gear opposite to the direction of movement of the belt.
  • the rolled strip is formed primarily in the width and at a much lower compared to the prior art share in the length, so that there are significantly fewer warps or corrugations of the tape.
  • bands can be produced, which consist essentially of only two strips of constant, different thickness but also those in which individual strips, viewed transversely to the conveying direction of the belt, have a step-shaped, in any case discontinuously increasing or decreasing strength
  • tapes can be made in which, for example, one or more grooves of different width or thickness are rolled into a tape.
  • strips with strips of piecewise constant thickness can be made across the strip running direction, but also strips with concave recesses or continuous thickness transitions. All you have to do is use a suitably shaped work roll and the matching sun and planet wheels.
  • the invention can be used not only for processing originally flat bands of constant thickness, but also for further processing semi-finished bands or profiles in which at least one strip of different thickness running in the longitudinal direction of the profile is produced by means of rollers, between which Profile performed while a strip of reduced strength is generated by a rolling process.
  • at least one puncture preferably a wedge-shaped groove in the region of Gradation between two strips is made.
  • This puncture can be made either by plastic deformation of the band, for example with a wheel pushing the puncture into the band, or by a machining operation, for example with a milling cutter or a planer.
  • each work roll can be easily freed from the flank. This reduces both the friction and the pressure on the edges of the work rolls.
  • a targeted manipulation of the thickness of the strip in the direction of tape travel is possible.
  • the forming process _. subsequent calibration rollers must be readjusted constantly in this case, in which case only the rolled thinner strip is re-rolled.
  • the strip may be rolled in at least two successive rolling operations. This can be advantageous, for example, when the strip to be rolled is either relatively wide or the strip thickness to be reduced is very large, so that a two-stage or multi-stage rolling process is advantageous. If a gradation is to be made on either side of the belt, in one embodiment of the invention, the belt may be rolled with two work rolls disposed on opposite sides of the belt.
  • a corresponding straightening roller pair may be provided in a further preferred embodiment of the invention.
  • These straightening rollers are said to reduce the minimum ripple after engagement of the work roll to the desired profile of requirements.
