Definitions

  • the present invention relates to a device for deburring and beveling flat pieces, such as sheets of whatever thickness, of iron or other materials, which can be either portable or connected to supporting systems with conveyor belt.
  • This operation is sometimes carried out in an unsatisfactory and unevenly way, by means of brushes rotating against the deburring edge, or by means of triangle-shaped tools scraping on the edge itself.
  • the present invention aims at removing the burrs from the edges in a uniform and regular way, thus obtaining a perfect deburring without any peculiar artifice.
  • the present invention consists of a pair of rotating abrasive belts which bevel through contact with their properly rotating surface.
  • Each belt is supported by a pair of pulleys (driving and driven one); the belts face the edges of the piece to be beveled.
  • One or both the rotation axes of the belt pulleys - the former for the upper edge, the latter for the lower one - are inclined at a suitable angle to form a "slide" at the leading end, to progressively remove the material, and to perfectly finish it, as a function of the abrasive belt width.
  • the relative motions are the rotation of the belts and the feed in of the piece towards the device, the two rotating belts between which it is operated being in touch with its edges.
  • These abrasive belts are mounted in a self-contained mechanic group which comprises, besides their motorization and guide on rotating pulleys, the other mechanical elements necessary for the functioning, being the two belts inclined at an opposite angle.
  • the device can be connected through plate 1 to a bench for the piece feed in, by means of screws.
  • piece 2 On the feed in plan, piece 2 is fed in from left to right passing between the abrasive belts 3 and 4, which are in touch with its upper and lower edge, respectively.
  • Figg. 2 and 3 show both the inclinations the rotating belts can have to carry out the required operation (in some cases, only one inclination can be given).
  • motorizations 6 and 7 On the driving pulleys, motorizations 6 and 7 are shown, and the pairs of pulleys 9-11 and 10-12 which make it possible the opposite rotation of each belt on the driven pulley (for instance, pulley 9 rotates clockwise, pulley 10 anticlockwise).
