Definitions

the invention relates to a pressing device with a press plate for hot pressing of pressed material from the group laminates, wood materials, wood-plastic materials, chipboard, wood-paper, foil and Pappkombinationen for floors, walls and ceilings, wherein the pressing device at least one heatable press plate and wherein between the pressure plate and the press plate at least one elastic coating is arranged.
heated pressing devices which may be parts of a single or platen press, it is to achieve short cycle times and uniform pressing effects in order to ensure the highest possible and uniform heat transfer and extremely uniform distribution of high compressive forces over the entire pressed material. It must be remembered that it can be pressed material dimensions of 6 m x 9 m and above.
Negative examples of poor heat transfer are - but there wanted - multiple glazing of windows and evacuated thermos.
a press pad for hot plate presses in which a fabric of a random fiber nonwoven fabric is coated on both sides with silicone rubber.
a press pad is known from a fabric of intersecting filaments, the core of which is, for example, a silicone elastomer thread having a Shore A hardness of 60 to 75 wrapped by at least one metal wire.
the metal wires can be connected as electrical heating resistors. Air pockets between the tissue and the pressed material are thereby not excluded.
the pure metal sheets or metal plates are referred to in practice, which can be referred to as a support plates as a result, because they have a supporting function for applied coatings and coatings of one or more components in practice.
a press plate for hot pressing of pressed material wherein a corrosion-resistant and scratch-resistant glass coating is applied to the press plate for the production of highly smooth surfaces on the pressed material, which is also not elastic in itself. Again, the elasticity to compensate for inhomogeneities in the surface of the pressed material does not matter.
a plate press for the production of wood-based panels which comprises an upper press plate and a structural plate arranged thereunder, between which a press pad is arranged, and wherein the structural sheet is held by vacuum on an elastically deformable support plate.
the support plate is attached at the open plate press together with the structural sheet hanging on the upper press plate. Due to the sagging structural plate, a rapid closing of the plate press is to be made possible because the air cushion between the upper structural plate and the pressed material pressed out easily when closing the plate press from the slits formed as a result of slack becomes.
the advantages in closing and opening the plate press can be achieved even if the press pad is missing. But then air bubbles can not be avoided.
the invention is based on the object of specifying a coated press plate of the type described above for hot pressing, with the short cycle times and uniform or full-surface pressing effects for the highest possible and uniform heat transfer by avoiding air inclusions and Kältenestern and an extremely uniform distribution of high pressing forces over the entire Pressing material, long service lives and a low product scrap are achieved, especially for pressed material dimensions up to 6 mx 9 m and above.
the application of the elastic coating can be done either by uniform brushing, extruding from a slot or by pouring a first easily flowable mass of one or more nozzles according to a predetermined, very narrow and uniform distribution pattern on the press plate, wherein the first flowable mass at least largely distributed by itself, and then let the mass stand up to reach the predetermined Shore A hardness, for which silicone resins are particularly well suited.
FIG. 1 2 shows a section of a press device 1, which denotes a machine lower part 2, also referred to as a machine table, and a press plate 3, also referred to as a machine upper part, which is movable in the vertical direction by a plurality of synchronously acting drive elements 4, wherein the drive elements are used as hydraulic actuators. or pneumatic cylinders, but can also be designed as mechanical drive elements such as spindle drives.
a press device 1 denotes a machine lower part 2, also referred to as a machine table, and a press plate 3, also referred to as a machine upper part, which is movable in the vertical direction by a plurality of synchronously acting drive elements 4, wherein the drive elements are used as hydraulic actuators. or pneumatic cylinders, but can also be designed as mechanical drive elements such as spindle drives.
the usual, these components surrounding press frame is not shown for simplicity. Since it is a device for hot pressing of pressed material 5, machine base 2 and press plate 3 are provided with heaters.
the pressed material 5 solidifies in itself, be provided with a flat decorative coating and / or a surface profiling such as a wood pattern.
a press plate 6 is suspended from metal, by vertical bends 6a with vertical slots 7 and horizontal screws 8 at the peripheral edge 3a of the press plate 3 and / or by vertical, preferably only in the edge region arranged countersunk screws 9, not from the Press plate 6 protrude below.
Decisive in this case is the intermediate layer of an inherently elastic covering 10 which is either single-layered or multi-layered in the vertical direction can be, or even in the horizontal direction zones or areas of different Shore A hardness may have. This will be discussed in more detail in connection with other figures.
those with Shore A hardnesses between 40 and 80 even better those with Shore A hardnesses between 50 and 70, in particular those with Shore A hardnesses of about 60 in question. It is according to DIN 53 505 to dimensionless units. Very suitable are silicones or silicone materials. It will be on the RöMMP CHEMIE LEXIKON, Edition 1995, page 4137 and pages 4168 to 4172 directed.
the elasticity of the lining 10 must be sufficiently high, on the other hand, but also the thermal conductivity, which can be improved by the incorporation of particles, tissues or networks of metal.
the thickness of the elastic covering 10 or the sum of all elastic layer components of the lining 10 is a range between 1 and 4 mm in question.
the compound of the lining 10 with the press plate 6 can preferably be improved by a bonding agent.
Such adhesion promoters or adhesives are known per se and are commercially available. Please refer RöMMP CHEMIE LEXIKON, 1995 Edition, pages 1703 and 1704 ,
FIG. 2 shows a vertical section through a press plate 6 with a single, single-layer elastic coating 10.
Die FIG. 3 shows a vertical section through a press plate 6 with an elastic covering 10, the zones or regions 10a and 10b of different Shore A hardness, having, preferably, the area 10a with the larger Shore A hardness above all over the entire peripheral region of the press plate 6 extends.
the FIG. 4 shows the item of FIG. 3 with an additional metal layer 11, eg a soft metal foil.
FIG. 5 shows a corner of a protruding edge 6 b pressing plate 6 with an elastic coating 10 after FIG. 2 on which a layer 11 made of a soft metal foil is applied, which is partially removed for better clarity.
the FIG. 6 shows a corner of a press plate 6 after FIG. 3 in plan view with zones or regions 10a and 10b of different Shore A hardnesses.
This layer design enables a compensation of different surface geometries of the pressed material 5 (FIG. FIG. 1 ). With the subject invention, it is possible to exert the same compressive forces on the pressed material 5 with each surface element of the lining at the same temperatures.
FIG. 7 shows a vertical section through a press plate 6 with a coating 10, which is composed alternately of three elastic layers 10c and two soft metal layers 11, which consist for example of copper sheet and / or a copper fabric with a thickness of 0.3 to 0.4 mm ,
