Definitions

  • the invention relates to a press according to the preamble of the main claim.
  • a press of this type is known from European Patent No. 0 128 968.
  • the pressure control devices for the lubricant associated with each groove of the sliding surface which groove has a discharge opening or a supply opening, for generating a counterpressure in the working gap of the press, such that the surface forces on the press belt and on the sliding surface can be absorbed more evenly by the lubricant.
  • the object of the invention is to provide a press of the type mentioned, with which a stable pressure and temperature situation in the working gap of the press can be maintained for long-term operation with the least possible design effort.
  • solution feature a) of the invention prevents an abrupt drop in pressure of the lubricant at the edges of the sliding surface compared to the atmospheric pressure by reducing the energy of the lubricant working pressure, which corresponds to the arrangement for the material to be pressed.
  • Solution feature b) of the invention is required, in the lubricant grooves, which are at least in the longitudinal edge regions of the sliding surface (solution feature a) of the invention), is destroyed as it were by turbulence graded very quickly. Because of this, both foaming of the lubricant such as oil or air separation from the oil and swirling or intensive mixing of the oil with the ambient air are reliably avoided.
  • grooves with a square, rectangular or trapezoidal cross section are already effective are easy to manufacture by milling. These grooves can also have an inclined position which, together with the tear-off edges of the grooves, increases the degree of swirling. Also advantageous are bevels of the groove walls, such as sawtooth-shaped contours, since they intensify the swirling of the lubricant.
  • Fig. 1 shows a section of a portion of a sliding coating for a continuously operating press with the features of the preamble of the main claim.
  • the total sliding surface of this press is composed of a plurality of such sliding surfaces arranged adjacent to one another.
  • the sliding coating 1 has feed openings 3 and discharge openings 4 for a liquid lubricant which is in suitable grooves - see, for example, those apparent from European Patent Specification No. 0 128 968 - takes on surface forces loading on the press belt 5 shown in FIG. 2.
  • the outer aligned grooves 10, 11 are less than half as long as the adjacent inner grooves 7,8.
  • a groove 9 which branches off perpendicularly from the central groove 8 and opens out at the edge 12 of the sliding coating 1.
  • the groove 9 provides an additional reduction in pressure of the lubricant swirled in the grooves 8 and 9 and thus ensures - see FIG. 2 in this regard - that the edge section 13 of the press belt 5 cannot lift off the sliding coating.
  • the grooves are in the edge area of the sliding lining 1 is rectangular in cross section and provided with tear-off edges 14, 15 and 16, whereby a seal is created in which the pressure of the lubricant can be reduced to atmospheric pressure.
  • the sliding lining 1 is on an abutment 17 and this on a press plate 18 in a suitable manner, e.g. fixed with screws.
  • the press belt 5 is pulled together with the material 19 to be pressed over the sliding lining 1; it forms a uniform, full-area and pressure medium-controlled lubricant layer of a constant thickness and speed between the press belt 5 and the sliding coating 1 to immediately at the tear-off edge 14 of the groove 7, which simultaneously heats the press belt 5 and the material 19 to be pressed, evenly Narrow surface 20 is aligned with the tear-off edge 14 of the groove 7, ensures and almost completely eliminates friction between the sliding coating 1 and the press belt 5.
  • a single and very simple scraper is usually sufficient to remove oil adhering to the lower surface of the edge section 21 of the press belt 5.
  • grooves 7, 8, 11 have a trapezoidal cross section, this widens from top to bottom. If the cross-section is parallelogram-shaped, they run Cross from top right to back left. The above definitions are based on the view according to FIG. 2.
