Definitions

  • the invention relates to a perforated brick according to the preamble of claim 1.
  • the aim of the invention is to avoid these disadvantages and to propose a brick of the type mentioned above, which is characterized by a high degree of sound insulation and / or thermal insulation with high pressure resistance.
  • Another object of the invention is to propose a method for producing a brick according to the invention.
  • Another object of the invention is od a mouthpiece for a screw press. Like. For the production of a perforated brick after the propose inventive method.
  • the cores may have a deviating from the circular cross-section; if they have a circular cross-section, then they must be mounted eccentrically.
  • By the rotatable mounting of such cores expediently provided with a wear-resistant surface and, for. hard chrome-plated or equipped with carbide, it is easily possible to put them during the extrusion in rotation and in this way to work in a sense twisted running helical surfaces in the webs between the individual holes.
  • the features of claim 5 ensures in a simple manner that openings are made in the webs in the longitudinal direction at some points between the channels formed by the rotatable and fixed cores.
  • Fig. 1 shows a perforated brick 10, which is made of a hardening silicate mass by extrusion.
  • This brick 10 has a series of holes 11, which pass from one end face to the second end face and between which webs 15 remain.
  • Fig. 2 which is, however, for reasons of simplicity, only a schematic representation and not a section through the brick 10 shown in FIG. 1, 10 are in the webs 15 of the tile screw surfaces 13, 14 incorporated, which have different pitch angle in the illustrated embodiment.
  • a screw press 1 comprises a pressing plate 2 with a rectangular outlet opening, wherein the pressing plate 2 carries a frame 3 of a mouthpiece 8.
  • the frame 3 is formed as a grid-shaped openwork rectangular frame.
  • core rods 4 are screwed or welded over the entire end face at intervals, each carrying a core 5 downstream. Together with a conical guide 6 of this mouthpiece determines a cross section for a perforated brick 10, as shown in Fig. 1 in plan view.
  • cross sections of the cores 5 with any contour are possible. Preference is given to regular polygonal figures, which have concave or convex connecting lines between their vertices and which are preferably rotatably mounted in their center. It can also be a circular cross section of the core 5 are selected, but must in In this case, the core 5 are mounted eccentrically for the formation of varying widths of the webs 15. Cores 5 have a particularly favorable effect on the sound insulation, which have a polygonal shape with uneven angular pitch.
  • FIG. 4 shows a core bar 4 with a core 5 attached at its downstream end, which is a self-propelling core 5 rotatably supported on the core bar 4.
  • a protective cap 20 covering the upstream end of the core 5 is provided.
  • the core 5 Secured is the core 5 with a sliding washer 21 and a cap nut 22, with a corresponding clearance is provided to allow easy rotation of the core 5 on the core rod 4.
  • the core 5 has a cross-section to be enlarged towards its downstream end and is provided on its lateral surface with a plurality of helically extending helical surfaces 24, whose pitch angle is expediently approximately between 5 ° and 45 °. These screw surfaces 24 cause the extruded silicate mass to rotate the core 5 during the extrusion. As a result, in the webs 15 between the holes 11 threaded surfaces 13, 14 incorporated, which - as can be seen from Fig. 2 - in brick 10 may also have different pitch angle.
  • FIGS. 5 and 6 show similar cores 5, 5 ', whose helical screw surfaces 24 rise in opposite directions.
  • Such cores 5, 5 ' are expediently attached to side by side arranged core rods 4 to form particularly strong wall thickness changes.
  • Fig. 7 shows a core 51 with substantially parallel ribs 25, wherein the core 51 widens against its downstream end.
  • the drive body is provided with at least one, but preferably at least two, an angle with the axes of the core rods 4 enclosing drive surface.
  • the angle which the drive surface includes with the core rods 4 is smaller than the complementary angle of the friction angle of the material pairing in order to avoid self-locking and to ensure rotation of the drive body due to the mass to be extruded.
  • the drive surfaces of the drive bodies can be formed by screw surfaces incorporated in the lateral surfaces of the drive bodies, similar to those of the cores 5, 5 '. But it is also possible to form the drive body similar to a propeller.
  • FIGS. 8 and 9 show further embodiments of cores 52 and 53, which are also provided with ribs 25 which have no slope. These cores 52, 53 require a rotationally fixed connection with a drive body.
  • FIG. 10 shows a section of an embodiment of a mouthpiece 8 according to the invention, alternating fixed cores 7 next to rotatable cores 5.
  • the cores 5, 7 must be aligned exactly parallel on their core rods 4. It should be noted that the cores 7 in practice not only have a rectangular cross-section, but other cross-sectional shapes are possible, which must be aligned prior to mounting on the core rods 4 accordingly.
  • the rotatable cores 5 directly adjoin the fixed cores 7.
