Definitions

  • the prior art in the field of forming ceramic tiles is based on the use of dies inserted into presses.
  • the dies are, schematically speaking, constituted by a cavity into which powders are deposited, and by at least one punch having the task of pressing the deposited powders.
  • dies in which the cavity is not made in the bottom die; this is instead used for depositing a layer of powders which is then pressed by the top die or punch.
  • Delimitation and lateral containment of the material to be pressed to form the tile or slab is performed by a forming frame associated to the punch or top die, which projects from the top die so that it can remain in contact with the bottom plane (bearing the powders to be pressed) during the pressing operation.
  • This solution exhibits a number of constructional complexities due to the need to predispose devices for vertically moving the frame with respect to the punch, and is subject to problems of wear on the moving parts.
  • a further and not easy-to-solve drawback concerns the need to provide a device for cleaning the punch between one pressing operation and a next.
  • the main aim of the present invention is to provide a device for forming ceramic products, such as slabs, tiles and the like, by power pressing, which will obviate the above-described drawbacks and limitations inherent in the prior art.
  • the invention is constructionally simple and functional.
  • a further advantage of the invention is the fact that it enables a punch-cleaning operation to be carried out between one pressing operation and a next both away from the pressing zone and easily.
  • the lower element 2 lies and slides along an upper surface of the piston 10 of the press 11 and is commanded by the piston 10 to displace upwards in order to exert the pressing action.
  • the upper element 4 is provided with a plurality of active surfaces 5, located and distributed in a predetermined order along the upper continuous belt 15. At each pressing event the active surfaces 5 are brought into contact with the rest plane 3 of the lower continuous belt 12.
  • Each active surface 5 is characterised in that it is provided with a forming frame 6 which projects inferiorly (when the active surface 5 is in contact with the rest plane 3) and is predisposed in such a way as to delimit at its perimeter a closed pressing zone.
  • a plurality of forming frames 6 can be predisposed on the upper continuous belt 15, each different from another, so that the type of surface to be obtained on the pressed product can be alternated.
  • the forming frame 6 exhibits an internal part 7 which carries out the pressing of the edge 22 of the final pressed product 21.
  • This internal part 7 is externally delimited by an edge 8 having a depth, measuring in the pressing direction, which is not less than or is equal to that of the central body of the final pressed product 21.
  • the internal part 7 inferiorly projects with respect to the active surface 5 and presents a breadth which gradually decreases as it distances from the edge 8.
  • the whole forming frame 6 is constituted by a material provided with a consistent elastic deformability (rubber or another elastomer).
  • the upper branch of the lower continuous belt 12 is moved in concordance with the lower branch of the upper continuous belt 15.
  • the lower rest plane 3 also functions as the bottom die of the forming device.
  • the piston 10 rises, raising the part of the lower element 2 on which the powder to be pressed has been deposited, thus pressing the powder against the active surface 5 delimited by the forming frame 6 of the upper continuous belt 15.
  • edges 8 have mainly the task of perimetrally defining the area of compression
  • the internal parts 7 have the function of realising, at the edge of the powder, a perimeter area of greater compression with respect to the central part of the powders, thus creating a more compacted zone at the edge of the pressed slab or tile.
  • An advantage of the present invention is that the slab- or tile-forming operation is rendered very simple and rapid, especially when the slabs or tiles are of large dimensions but are relatively slim.
