Definitions

  • the invention relates to an apparatus for distressing solid objects, such as for example ceramic glazes, masonry, stone, wood; and also articles made of cast materials such as bronze and stainless steel.
  • the distressing operation gives the piece a particular surface abrasion, and be used for example for deburring cast pieces, obtaining smooth surfaces free of burrs; or, if a deeper operation is performed, for giving a surface a particular surface roughness, an effect which is especially appreciated in covering materials, which gain a worn and antiquated appearance because of the lack of sharp edges it leaves, and for the "lived-in" look of the surfaces produced.
  • This lived-in or aged look is obtained in nature by a long period spent on a river bed.
  • the prior art includes using mills substantially constituted by a trunco-cylindrical drum, quite broad, which is partially filled with a mixture of spheres, or balls, made of a hard material (such as silicon, or treated alubit) and water, and rotated according to the axis of symmetry of the cylinder for a certain time, such as to reduce the pieces introduced therein to powder, thanks to the cyclic motion of revolution, contact and rubbing of the materials contained.
  • a hard material such as silicon, or treated alubit
  • the drum For more fragile pieces it is preferred to fill the drum with water, dispensing with the presence of spheres or balls made of a hard material, and proceeding to rotate the drum by means of an external motor, for a certain time.
  • the product to be treated is introduced into the drum through a sealed hatch and distressed for a certain time, perhaps multiples of ten minutes, according to the characteristics of the product (harder or less hard), and the surface effect desired.
  • the known apparatus for distressing exhibit some drawbacks.
  • the aim of the present invention is to obviate the above-mentioned drawbacks, by providing an apparatus which is able to distress correctly, even operating on solid bodies in which the length is prevalent with respect to the other two dimensions, with cycles having a particularly contained duration.
  • 1 denotes in its entirety an apparatus for distressing solid pieces, made according to the invention.
  • 2 denotes a sturdy base frame superiorly provided with two rolling supports 6 on which a drum 3 rotates according to an axis 10 thereof.
  • the axis 10 is preferably arranged horizontally.
  • the drum 3 is constituted by a trunco-cylindrical central part 4, and by two heads 5.
  • the internal wall of the drum 3 is covered with a known anti-abrasion material, such as for example panels made of a hard polyurethane.
  • the cylindrical part 4 is provided with a central axis of symmetry 11, which does not coincide with the rolling axis 10 of the drum 3.
  • the two axes 10 and 11 form an angle ⁇ , a value of which depends on the type of the material being worked.
  • the value of the angle ⁇ is comprised between 10 and 20 degrees; while for materials or pieces which are not fragile, such as for example cast pieces to be deburred, or for the milling of ceramic glazes, the value of angle ⁇ is comprised in the range from 30 to 40 degrees.
  • Motors 7 are provided, powered by an electric motor 8 controlled by a known-type electronic card which can vary the rotation speed continuously and freely.
  • a hatch 9 of known type is located on the wall of the drum 3 for introducing/evacuating the contents thereof, which are introduced discontinuously.
  • the drum After introducing the material to be distressed and closing the hatch 9, the drum is rotated according to the horizontal axis 10. As this axis does not coincide with the axis of symmetry of the drum 3, an oscillation of the drum 3 is produced which superposes the rotation movement.
  • Figure 2 shows the position of the drum 3 after half a revolution: note that in this position the inclination of the drum is inverted with respect to the start position.
  • the above-described apparatus can be used not only for distressing but also for milling, for example in the ceramic field, leading to important advantages also in the latter field.
