Definitions

  • the invention relates to a device and a method for processing a band-shaped or plate-shaped metallic workpiece, in particular for removing the oxide layer of cut surfaces and / or cut edges of the workpiece.
  • an oxide layer or an oxide skin is formed at the cut edges and at the cut surfaces.
  • a disadvantage of the oxide layer is that a paint or zinc coating applied to it bounces off relatively quickly. For this reason, the metallic workpieces are ground off before painting and galvanizing.
  • the generic document shows a method and apparatus for removing the oxide skin on metal blanks.
  • the metal blank is used to remove the oxide layer passed from the cut surfaces between paired, rotating, machining tools.
  • the outer cut surfaces of the oxide layer can be cleaned by this method, it is not possible to remove the oxide layer from inner cut surfaces, for example from recesses or similar openings in the workpiece.
  • the metal blank must be fed to a further processing device, if the surface or the main surface of the workpiece to be cleaned or cleaned.
  • a disadvantage of the device of the generic document is also the handling, and the cost-intensive design and high space requirements.
  • the processing tools use uneven, since it is generally assumed that the metal blanks to be descaled always in the same area, i. in the same place, so that one part of the machining tool never comes into contact with the metal blank, while another part of the machining tool is subject to permanent wear.
  • Devices for deburring and fine grinding are also known from the general state of the art.
  • both rollers and plate-shaped, rotating brush tools are used.
  • the workpiece to be machined is placed on a horizontal working plane or a conveyor belt and performed under the roller or the rotary brush tool by hand or automatically.
  • Such machines can for example have a working width of 1 to 2 m, but in practice usually equipped with smaller metal blanks. This has the consequence that a roll with for example 2 m in length is only claimed on the first 50 cm of its length of metal blanks and thus wears only in this area.
  • the roller must be replaced as soon as this area is worn out too much, although three quarters of the roller surface is still well preserved and usable. An exchange is therefore unavoidable, since when introducing a large workpiece now no longer grind the first 50 cm of the roller. The uneven wear of the roller and the resulting different pressure on the workpiece result in inferior grinding results. On the quality of deburring or grinding also has a negative effect that the brush or the roller is not infinitely adjustable in their penetration depth. An inherently meaningful, deep penetration of the bristles is prevented by the conveyor belt on which the workpiece lies, as this should not be damaged.
  • a disadvantage of the known deburring and grinding machines is also that the workpiece must be inserted twice so that both main surfaces of the workpiece can be edited.
  • Another disadvantage of the known machines is the high drive power, the high space requirement and the high acquisition and maintenance costs.
  • the basic surfaces of the machines are dimensioned so that even the largest workpieces can be inserted and processed flat.
  • the base requires at least such a space requirement. Added to this is the space required for placing and aligning the piece of metal prior to insertion into the machine and for removal.
  • the present invention has for its object to solve the above-mentioned disadvantages of the prior art, in particular a fast, simple and inexpensive device and a method for processing strip or plate-shaped metallic workpieces, in particular for removing the oxide layer of cut surfaces and / or cut edges to create the same.
  • the brush does not remain rigidly in one position due to the arrangement on a circulating conveyor, but is guided along the entire length which is present for the passage of the workpiece, a uniform wear of the at least one brush is ensured.
  • the workpiece can be carried out in a simple manner obliquely, preferably transversely to the direction of rotation of the brush or pulled through, so that the workpiece is processed uniformly by the brush.
  • the brush thus moves obliquely or transversely to the feed direction of the workpiece along the workpiece and, similar to a brush, which is pulled along on a metal piece, penetrates into each recess.
  • both the surfaces, ie the main surfaces of the band- or plate-shaped metal workpieces are processed, and the cut surfaces and cut edges descaled. Simultaneous descaling of the cut surfaces and cut edges and cleaning of the surfaces was not possible with the previously known devices. It is advantageous if two conveyors are provided, between which the workpiece obliquely or transversely to the direction of rotation is feasible such that each conveyor with the associated brushes processed one of the two main surfaces of the workpiece.
  • both main surfaces of the workpiece are thereby processed with one operation.
  • the cut edges as well as the cut surfaces are machined from both sides, so that a particularly thorough descaling takes place.
  • the use of two conveyors allows a fast and rational machining of the workpiece.
  • the conveying devices have a plurality of brushes arranged at a distance from one another.
  • the distance between the brushes ensures that the brushes each hit unbelted on the workpiece or advantageously penetrate into recesses or holes.
