Abstract

In a platen press, in particular for the vulcanisation of conveyor belts and for the production of fibre plates, chipboards or the like, having a press table (1), an upper crosspiece (6) and if appropriate a central table (7), as well as heating plates (5) adjoining the latter with insulating plates (3) in between, and if appropriate further heating plates at different levels, the insulating plates (3) have, at least on one of their two surfaces, groove-like depressions (8) extending as far as the edges. The depressions (8) ensure better and more uniform gas removal from the plates when subjected to thermal stressing, because the gases can escape to the outside, with the result that, on the one hand, gas bubble or gas cushion formation between insulating plate (3) and heating plate (5) cannot occur, and, moreover, deformation of the plates is avoided. Furthermore, the groove-like depressions (8) permit an equalisation of thickness differences in the plates due to manufacture, in that they act as compensation zones and take up the material displacement. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Plattenpresse mit Pressentisch, Oberholm und ggf. einen Mitteltisch sowie an diesen unter Zwischenschaltung von Isolationsplatten angeschlossenen Heizplatten. Ferner können ggf. weitere Etagenheizplatten vorgesehen sein.The invention relates to a plate press with a press table, upper spar and possibly a center table and heating plates connected to these with the interposition of insulation plates. Furthermore, further floor heating plates can optionally be provided.

Plattenpressen der vorerwähnten Gattung werden insbesondere zur Vulkanisation von Förderbändern sowie zur Herstellung von Faserplatten, Spanplatten od.dgl. eingesetzt. Die Isolationsplatten haben die Aufgabe, den Wärmefluß von den Heizplatten zu dem Oberholm, dem Pressentisch bzw. ggf. auch dem Mitteltisch zu dämmen, um einerseits diese Teile thermisch nicht zu stark zu beanspruchen und um andererseits die Wärme im wesentlichen für den eigentlichen Preßvorgang zur Verfügung zu haben.Plate presses of the aforementioned type are used in particular for the vulcanization of conveyor belts and for the production of fiberboard, chipboard or the like. used. The insulation plates have the task of insulating the flow of heat from the heating plates to the upper spar, the press table or possibly also the center table, in order not to subject these parts to excessive thermal stress and on the other hand to essentially provide the heat for the actual pressing process to have.

Die Isolationsplatten selbst bestehen im wesentlichen aus Asbest, Glasgewebe und/oder schlecht leitenden Füllstoffen. Als Bindemittel werden meistens Kunstharze oder mit Kautschuk modifizierte Harzgemische, beispielsweise Silikon, von Fall zu Fall auch Zement, verwendet. Jedenfalls sind die Isolationsplatten regelmäßig von solcher Struktur, daß sie Feuchtigkeit aufnehmen können und dementsprechend in den Platten immer eine gewisse Restfeuchte vorhanden ist.The insulation panels themselves consist essentially of asbestos, glass fabric and / or poorly conductive fillers. Most of the time, synthetic resins or rubber mixtures modified with rubber, for example silicone, and sometimes also cement, are used as binders. In any case, the insulation plates regularly of such a structure that they can absorb moisture and, accordingly, there is always a certain residual moisture in the plates.

Diese Restfeuchte und auch die Tatsache, daß die Bindemittelkombinationen mit Ausnahme von Zement unter Druck und Hitze in gasförmiger Form Reste von beispielsweise Phenol, Kresol oder auch Formaldehyden abscheiden, wobei je nach Beanspruchung und Hitze Druckbeaufschlagung Uberkondensationen entstehen, führen sowohl dazu, daß sich die Isolierplatten im wesentlichen konkav oder konvex verformen als auch an Festigkeit und Formbeständigkeit verlieren.This residual moisture and also the fact that the binder combinations with the exception of cement under pressure and heat in gaseous form separate residues of, for example, phenol, cresol or also formaldehyde, whereby depending on the stress and heat pressurizing overcondensation both lead to the insulation plates deform essentially concave or convex and lose strength and dimensional stability.

Es ist ferner bekannt, bei sehr großen Pressentischen die Isolierplatten, die quadratisch oder rechteckig sein können, stückweise aneinanderzulegen, so daß eine Isolationsplatte aus mehreren Teilplatten besteht. Insbesondere bei derartigen Teilplatten sind fertigungstechnisch gewisse Dickenunterschiede nicht vermeidbar. Diese Dickenungenauigkeiten führen zu sogenannten Spitzenträgern, die spezifisch höher belastet und auch thermisch höher beaufschlagt werden.It is also known to piece together the insulating plates, which can be square or rectangular, in very large press tables, so that an insulation plate consists of several partial plates. In particular with such partial panels, certain differences in thickness cannot be avoided in terms of production technology. These inaccuracies in thickness lead to so-called tip carriers, which are subjected to a higher specific load and are also subjected to a higher thermal load.

Es besteht dementsprechend einerseits die Aufgabe, die aufgrund der Restfeuchte usw. auftretende ungleiche Verspannung bzw. Deformierung und sogar Zerstörung der Isolationsplatten zu verhindern und darüberhinaus insbesondere bei Teilplatten Dickenungenauigkeiten auszugleichen.Accordingly, there is on the one hand the task of preventing the uneven tensioning or deformation and even destruction of the insulation plates which occurs due to the residual moisture etc. and, moreover, of compensating for thickness inaccuracies, particularly in the case of partial plates.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß die Isolationsplatten wenigstens auf einer ihrer beiden Oberflächen bis zu den Rändern reichende nutartige Vertiefungen aufweisen. Diese Vertiefungen gewährleisten bei thermischer Beanspruchung, ein besseres und gleichmäßigeres Abgasen der Platten, weil die Gase nach außen austreten können, so daß es einerseits nicht zu Gasblasen- oder Gaskissenbildung zwischen Isolier- und Heizplatte kommen kann und daruberhinaus die Verformung der Platten vermieden wird. Darüberhinaus ermöglichen die nutartigen Vertiefungen eine Egalisation fertigungsbedingter Dickenunterschiede der Platten, in dem sie als Ausgleichszonen wirken und die Materialverdrängung aufnehmen.This object is achieved in that the Isolation plates have at least on one of their two surfaces to the edges groove-like depressions. In the event of thermal stress, these depressions ensure better and more even exhausting of the plates, because the gases can escape to the outside, so that on the one hand there can be no gas bubbles or gas cushion formation between the insulating and heating plates and, in addition, the deformation of the plates is avoided. In addition, the groove-like depressions enable the production of differences in the thickness of the panels due to production, in which they act as compensation zones and absorb the material displacement.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die nutartigen Vertiefungen heizplattenseitig. auf der Oberfläche der Isolationsplatte vorgesehen sind, d.h. also im Bereiche der größsten Wärmebeaufschlagung. Auch dadurch wird ein besonders günstiges Abströmen des Gases gewährleistet.According to a further feature of the invention it is provided that the groove-like depressions on the hotplate side. are provided on the surface of the insulation plate, i.e. So in the area of the greatest heat exposure. This also ensures a particularly favorable outflow of the gas.

Ferner sollen erfindungsgemäß die nutartigen Vertiefungen sich rasterartig durchkreuzend auf den Isolierplatten angeordnet sein. Dadurch wird eine vorteilhafte flächenmässige Aufteilung erreicht, so daß einerseits die Dickenunterschiede ausgesprochen günstig ausgeglichen und darüberhinaus eine Vielzahl von Gasungskanälen gebildet werden. Dies wird besonders gut gewährleistet, wenn der Abstand der nutartigen Vertiefungen etwa 50 bis 200 mm beträgt.Furthermore, according to the invention, the groove-like depressions should be arranged in a grid-like manner on the insulating plates. This achieves an advantageous division in terms of area, so that, on the one hand, the differences in thickness are compensated extremely favorably and, in addition, a multiplicity of gassing channels are formed. This is ensured particularly well if the distance between the groove-like depressions is approximately 50 to 200 mm.

Um ein Verrutschen bei der Ausführungsform, bei der die Isolationsplatte aus mehreren Teilplatten besteht, zu verhindern, ist ferner vorgesehen, daß zwischen den Teilplatten Distanzkreuze angeordnet sind. Dabei können zweckmäßig die Distanzkreuzarme kürzer als die Kantenlänge und/oder dünner als die Dicke der Teilplatten sein. Dadurch werden zusätzliche Abgasungsräume bzw. Abgasungskanäle und Ausgleichszonen für die Dickenunterschiede der Teilplatten gebildet.To prevent slipping in the embodiment in which the insulation plate consists of several partial plates prevent, it is further provided that spacer crosses are arranged between the partial plates. In this case, the spacer cross arms can expediently be shorter than the edge length and / or thinner than the thickness of the partial plates. As a result, additional exhaust gas spaces or exhaust gas channels and compensation zones for the differences in thickness of the partial plates are formed.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels näher veranschaulicht. Es zeigen:

  • Fig. 1 in schematisch gehaltener perspektivischer Darstellung eine Plattenpresse mit Mitteltisch und
  • Fig. 2 ebenfalls in perspektivischer Darstellung vier nebeneinandergelegte Teilplatten mit Distanzkreuzen in vergrößerter Darstellung.
In the drawing, the invention is illustrated in more detail using an exemplary embodiment. Show it:
  • Fig. 1 in a schematic perspective view of a plate press with center table and
  • Fig. 2 also in a perspective view four partial plates placed next to each other with spacer crosses in an enlarged view.

Gemäß Fig. 1 weist die Plattenpresse einen Pressentisch 1 auf, der über eine Zylinderkolbenanordnung 2 heb- und senkbar ist. Auf dem Pressentisch 1 ist zunächst eine im ganzen mit 3 bezeichnete Isolationsplatte, die aus mehreren Teilplatten 4 besteht, angeordnet. Oberhalb der Isolationsplatte 3 befindet sich die eigentliche Heizplatte 5.1, the plate press has a press table 1, which can be raised and lowered via a cylinder piston arrangement 2. On the press table 1, an insulation plate, designated as a whole by 3 and consisting of several partial plates 4, is initially arranged. The actual heating plate 5 is located above the insulation plate 3.

Die Presse weist ferner einen Oberholm 6 auf, der an dem - nicht gezeigten Pressenteil - als Widerlager ortsfest angeordnet ist. An dem Oberholm 6 sind in gleicher Weise wie am Pressentisch 1 eine Isolationsplatte 3 aus mehreren Teilplatten 4 sowie eine Heizplatte 5 vorgesehen.The press also has an upper spar 6, which is arranged in a stationary manner on the press part (not shown) as an abutment. In the same way as on the press table 1, an insulating plate 3 comprising a plurality of partial plates 4 and a heating plate 5 are provided on the upper beam 6.

Schließlich weist die Plattenpresse noch einen Mitteltisch 7 auf, der ober- und unterseitig mit Isolationsplatten 3 und Heizplatten 5 bestückt ist.Finally, the plate press also has a center table 7 which is equipped with insulation plates 3 and heating plates 5 on the top and bottom.

Die Isolationsplatten 3 bzw. die Teilplatten 4 sind, wie insbesondere aus der vergrößerten Darstellung gemäß Fig. 2 hervorgeht, an ihrer einen Oberfläche mit nutartigen Vertiefungen 8 versehen, die die Teilplatten 4 rasterartig orthogonal durchkreuzen und so angeordnet sind, daß ihre Öffnungen jeweils zu den Heizplatten 5 weisen.The insulation panels 3 and the sub-panels 4 are, as can be seen in particular from the enlarged representation according to FIG. 2, provided on one surface with groove-like depressions 8 which cross the sub-panels 4 orthogonally like a grid and are arranged such that their openings each to the Point heating plates 5.

Damit die Teilplatten 4 nicht gegeneinander verrutschen können, sind ferner Distanzkreuze 9 vorgesehen, die jeweils zwischen vier Teilplatten 4 angeordnet werden und diese auf exakter Distanz halten. Ein Verrutschen der Teilplatte 4 gegeneinander ist nicht möglich. Der besseren Übersicht wegen ist das Distanzkreuz 9 in Fig. 2 herausgehoben dargestellt. Da die Distanzkreuzarme sowohl kürzer als die Kantenlänge als auch dünner als die Dicke der Teilplatten 4 ausgebildet sein können, werden zusätzliche Kanäle 10 gebildet.So that the partial plates 4 cannot slip against each other, spacer crosses 9 are also provided, which are each arranged between four partial plates 4 and hold them at an exact distance. Slipping of the partial plate 4 against one another is not possible. For the sake of clarity, the spacer cross 9 is shown highlighted in FIG. 2. Since the spacer cross arms can be both shorter than the edge length and thinner than the thickness of the partial plates 4, additional channels 10 are formed.

Zwischen dem Pressentisch 1 und dem Mitteltisch 7 sowie dem Oberholm 6 und dem Mitteltisch 7 können selbstverständlich zur Bildung mehrerer Preßetagen weitere Heizplatten - ohne Isolationsplatten 3 - vorgesehen sein. Andererseits kann auch lediglich eine Einetagenpresse Verwendung finden, bei der nur ein Preßraum zwischen Oberholm 6 und Preßtisch 1 vorgesehen ist. Schließlich sind auch Mehretagenpressen ohne Mitteltisch, bei denen die weiteren Etagen ausschließlich aus Heizplatten bestehen, einsetzbar.Between the press table 1 and the center table 7 as well as the upper beam 6 and the center table 7, further heating plates - without insulation plates 3 - can of course be provided to form several pressing days. On the other hand, only a single-day press can be used, in which only one press space is provided between the upper beam 6 and the press table 1. Finally, multi-daylight presses without a center table, where the other floors consist exclusively of heating plates, can also be used.
