Definitions

  • the application relates to a device for the simultaneous production of a plurality of essentially block-like pressing bodies with a press consisting of a pressing tool upper part and a pressing tool lower part, in which the pressing tool lower part consists of a frame having a plurality of shafts, which can be raised and lowered and stamps arranged in a fixed manner in the shafts.
  • Such a device is known (DE - C - 23 09 975).
  • the known device is used to press compacts from a non-flowable mixture.
  • the non-flowable mixture often consists of lignocellulosic fibrous materials, such as chopped and dried wood chips, bagasse fibers and the like. ⁇ ., which are mixed with a thermosetting synthetic resin such as melamine, urea formaldehyde or phenol formaldehyde resin.
  • a thermosetting synthetic resin such as melamine, urea formaldehyde or phenol formaldehyde resin.
  • fibers of other materials such as glass fibers, rock wool or asbestos fibers, can also be mixed alone or several of these, to which appropriate, preferably organic binders have been added.
  • a press body is produced from the mixture in the press in such a way that the mixture is pressed under high pressure and heat, the binder hardening. If the pressing is carried out with a multiple pressing tool, it is necessary that very small distances are maintained between the punches and the shaft walls. If this is not the case, then in particular fine-grained constituents of the mixture can fall through the gap. However, if the distances are very small, it can, among other things Because of the temperature gradient in the tool, the shaft surfaces and / or the punches suffer increased wear.
  • the technical problem underlying the invention is therefore to improve the known device in such a way that increased wear is avoided despite the very small distances between the punches and shaft walls.
  • the punch end which is effective during pressing and which is to be tightly sealed with respect to the shaft wall is designed to be floating and can automatically adjust its position in the shaft as a function of temperature fluctuations.
  • the frame 2 provided with shafts 1 can be seen in the figure.
  • the punches 3 are arranged in the shafts 1, the upper end of which is provided with the horizontally balanced plate 4.
  • the plates 4 should be in the direction of the arrows be agile.
  • the upper end of the punch 3 is provided with a T-shaped profile and the plate 4 with a recess shaped in the same way.
  • the stamps 3 have in the center a closed longitudinal bore 5 at the upper end of the stamp 3, in which a heater is to be arranged.
  • the heating can be implemented, for example, in such a way that the longitudinal bore 5 is divided by a longitudinal wall into two channels which are connected to one another at the upper end and through which superheated steam is passed for heating purposes.
  • the heating can also be implemented in another way, for example by means of electric radiators.
