Description

Die Erfindung betrifft eine Presse zur Herstellung von gepreßten Profilkörpern aus einem nicht steigfähigen Gemisch von mit einem wärmehärtenden Bindemittel vermischten Faserstoffen, welche wenigstens ein entsprechend einer Seite des zu pressenden Profilkörpers geformtes inneres Preßwerkzeugteil und ein über das innere Preßwerkzeugteil greifendes äußeres Preßwerkzeugteil besitzt.The invention relates to a press for the production of pressed profile bodies from a non-rising mixture of fibrous materials mixed with a thermosetting binder, which has at least one inner pressing tool part shaped according to one side of the profile body to be pressed and an outer pressing tool part reaching over the inner pressing tool part.

Eine derartige Presse ist bekannt (DE-C-25 48 739). Sie ist vorgesehen, um Profilkörper, wie Außen- und Innenverkleindungsprofile für Hochbauten, Balkonverkleidungen, Tischplatten oder dgl., aus einem nicht steigfähigen Gemisch von mit einem wärmehärtenden Bindemittel vermischten Faserstoffen zu pressen.Such a press is known (DE-C-25 48 739). It is intended to press profile bodies, such as external and internal cladding profiles for buildings, balcony cladding, table tops or the like, from a non-rising mixture of fibrous materials mixed with a thermosetting binder.

Das nicht steigfähige Gemisch besteht meist aus lignozellulosehaltigen Faserstoffen, wie zerkleinerten und getrockneten Holzspänen, Bagassefasern u. a., die mit einem wärmehärten den Kunstharz, wie einem Melamin- Harnstofformaldehyd- oder Phenolformaldehydharz vermischt sind. Anstelle der zerkleinerten und getrockneten Holz- oder Bagassefasern können aber auch Fasern anderer Werkstoffe, wie Glasfasern. Steinwolle oder Asbestfasern, allein oder mehrere derselben miteinander gemischt, verwendet werden, denen entsprechende, vorzugsweise organische, Bindemittel zugesetzt sind.The non-rising mixture usually consists of lignocellulosic fibrous materials, such as shredded and dried wood shavings, bagasse fibers and the like. a., which are mixed with a thermosetting resin, such as a melamine-urea-formaldehyde or phenol-formaldehyde resin. Instead of the shredded and dried wood or bagasse fibers, fibers of other materials, such as glass fibers, can also be used. Rock wool or asbestos fibers, alone or several of them mixed together, to which appropriate, preferably organic, binders have been added.

Die Profilkörper werden in der Regel in der Weise hergestellt, daß zunächst aus dem Gemisch durch Kaltpressen ein Vorpreßling hergestellt wird, der auf seiner Unterseite, das ist die nicht als Sichtseite verwendete Oberfläche des Profilkörpers, mit einer Deckschicht versehen ist. Zu diesem Zweck wird aus dem Gemisch in einer Presse ein dem fertigen Profilkörper bereits sehr ähnlicher Vorpreßling gepreßt. Obwohl bei diesem Vorpressen des Profilkörpers diesem nicht die zum Aushärten des wärmehärtenden Bindemittels erforderliche Wärmemenge zugeführt worden ist, ist der Vorpreßling schon ein fester, handhabbarer Körper.The profile bodies are usually produced in such a way that a pre-compact is first produced from the mixture by cold pressing, which is provided on its underside, that is, the surface of the profile body not used as a visible side, with a cover layer. For this purpose, a pre-compact which is very similar to the finished profile body is pressed from the mixture in a press. Although during this pre-pressing of the profile body the amount of heat required to harden the thermosetting binder has not been supplied, the pre-compact is already a solid, manageable body.

Aus dem Vorpreßling entsteht durch das Hei- βpressen in einer anderen Presse der fertige Profilkörper. Beim Heißpressen wird der Profilkörper in der Regel gleichzeitig mit einer Deckschicht versehen, welche meist aus wenigstens einer Schicht besteht, nämlich einer Dekorschicht, beispielsweise aus einem Gewebe, einem Furnier, einer bedruckten Papierfolie oder einer Kunststoffolie, über der eine transparente Schutzschicht angeordnet sein kann. Als Schutzschicht dient meist ein sogenanntes Overlay-Papier, bestehend aus nicht gefülltem Alpha-Zellulosepapier oder Glasfaservlies, das mit einem Duroplast, meist auf Melaminbasis, getränkt ist. Die transparente Schutzschicht kann auch dadurch erzeugt werden, daß die Dekorschicht eine stärkere Harzschicht besitzt.The finished profile body is created from the pre-pressed product by hot pressing in another press. In hot pressing, the profile body is usually simultaneously provided with a cover layer, which usually consists of at least one layer, namely a decorative layer, for example made of a fabric, a veneer, a printed paper film or a plastic film, over which a transparent protective layer can be arranged. A so-called overlay paper, consisting of unfilled alpha cellulose paper or glass fiber fleece, is usually used as a protective layer and is impregnated with a thermoset, usually based on melamine. The transparent protective layer can also be produced in that the decorative layer has a stronger resin layer.

Die bekannte Presse hat sich bei der Herstellung der eingangs erwähnten Profilkörper in großem Umfang bewährt. Es konnte jedoch gelegentlich beobachtet werden, daß die Ränder der fertigen Profilkörper eine rauhe Oberfläche und ein optisch unansehnliches Aussehen aufwiesen. Da bei der bekannten Presse die Kanten des äußeren und des inneren Preßwerkzeugsteils, die beim Preßvorgang aneinander entlang gleiten, in einem rechten Winkel ausgebildet sind, ist angenommen worden, daß die Preßwerkzeugteile beim Preßvorgang eine Quetsch- und Scherwirkung sowohl auf die Kanten des Vorpreßlings als auch auf die Deckschicht ausüben.The known press has proven itself on a large scale in the manufacture of the profile bodies mentioned at the beginning. However, it was occasionally observed that the edges of the finished profile body had a rough surface and an optically unsightly appearance. Since in the known press the edges of the outer and inner pressing tool parts, which slide along each other during the pressing process, are formed at a right angle, it has been assumed that the pressing tool parts during the pressing process have a squeezing and shearing effect on both the edges of the pre-compact and exert on the top layer.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Presse zur Herstellung von Profilkörpern der eingangs geschilderten Art zu schaffen, mit welcher einwandfrei glatte und ebene Kanten an den Profiikörpern erzielt werden können.The invention is therefore based on the object of providing a press for the production of profile bodies of the type described at the outset, with which perfectly smooth and flat edges on the professional bodies can be achieved.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß der innere, dem inneren Preßwerkzeugteil zugewandte Rand des äußeren Preßwerkzeugteils eine mit der Preßrichtung sowie mit der seitlichen Begrenzungsfläche des inneren Preßwerkzeugteils einen spitzen Winkel einschließende, nach außen geneigte schräge Fläche bildet, an welche sich nach außen eine waagerechte Fläche anschließt.This object is achieved according to the invention in that the inner edge of the outer pressing tool part facing the inner pressing tool part forms an outwardly inclined inclined surface with the pressing direction and with the lateral boundary surface of the inner pressing tool part, against which a horizontal surface is formed on the outside Area connects.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen 2 bis 4 enthalten, welche nachstehend anhand der Figur erläutert sind.Further advantageous embodiments of the invention are contained in claims 2 to 4, which are explained below with reference to the figure.

Die Figur zeigt - im Wesentlich schematisch - den Querschnitt einer solchen Presse. Sie besteht aus dem Pressentisch 1, der in dem gezeigten Ausführungsbeispiel feststehend angeordnet sein soll, und dem in Richtung der Pfeile beweglichen Preßstempel 2. An dem Preßstempel 2 ist das äußere Preßwerkzeugteil 3 und an dem Pressentisch 1 das innere Preßwerkzeugteil 4 befestigt.The figure shows - essentially schematically - the cross section of such a press. It consists of the press table 1, which is to be arranged to be stationary in the exemplary embodiment shown, and the press die 2 which is movable in the direction of the arrows. The outer press tool part 3 is fastened to the press die 2 and the inner press tool part 4 is fastened to the press table 1.

In die Preßwerkzeugteile sind die Konturen des zu pressenden Profilkörpers eingearbeitet. Die Verdichtung des Profilkörpers wird durch die Dicke des zwischen äußerem Preßwerkzeugteil 3 und innerem Preßwerkzeugteil 4 eingeschlossenen Raumes in der Preßendstellung bestimmt. Beim Pressen wird die Bewegung des Preßstempels 2 durch die Anschläge 5 und 6 begrenzt, welche in der Preßendstellung miteinander in Kontakt sind.The contours of the profile body to be pressed are worked into the pressing tool parts. The compression of the profile body is determined by the thickness of the space enclosed between the outer press tool part 3 and the inner press tool part 4 in the final press position. During pressing, the movement of the press die 2 is limited by the stops 5 and 6, which are in contact with one another in the press end position.

Bei der neuen Presse ist der innere Rand des Preßwerkzeugteils 3 in dem Bereich, in dem sich beide Preßwerkzeugteile in Preßendstellung übereinander greifen, mit der schrägen Fläche 7 versehen, welche weiter außen in eine waagerechte Fläche 8 übergeht. Die Strecke, auf welcher das äußere und das innere Preßwerkzeugteil in der Preßendstellung dicht beieinanderliegend übereinander greifen, sollte wenigstens dem Dickenschwund des Profilkörpers beim Heißpressen entsprechen.In the new press, the inner edge of the pressing tool part 3 is provided with the inclined surface 7 in the area in which both pressing tool parts overlap in the pressing end position, which transitions further into a horizontal surface 8. The distance on which the outer and the inner pressing tool part in the pressing end position engage closely together should at least correspond to the thickness loss of the profile body during hot pressing.

Diese Gestaltung des Preßwerkzeugteils 3 hat folgende Wirkung : Der Vorpreßling wird - wie bereits bereits geschildert - nach dem Vorpressen aus der Presse entnommen und in das Preßwerkzeugteil 4 der geöffneten Heißpresse eingelegt. Da jeder Vorpreßling - wie allgemein bekannt - nach dem Vorpressen atmet, d. h. beim Öffnen der Vorpresse infolge Zurückfederns der Preßmasse eine Volumenvergrößerung erfährt, ragt der Vorpreßling über die Außenmaße des Preßwerkzeugteils 4 hinaus. Wird nun das Preßwerkzeugteil 3 der Heißpresse auf das Preßwerkzeugteil 4 mit dem darin liegenden Vorpreßling abgesenkt, dann drückt die schräge Fläche 7 die überstehenden Teile des Vorpreßlings kontinuierlich nach innen, ohne den Vorpreßling zu beschädigen. Zu diesem Zweck sollte die schräge Fläche 7 eine möglichst glatte Oberfläche besitzen. Die Höhe und die Neigung der schrägen Fläche sind von der Form des Profilkörpers abhängig und lassen sich erforderlichenfalls durch einfache Versuche ermitteln.This design of the pressing tool part 3 has The following effect: The pre-compact is - as already described - removed from the press after the pre-pressing and inserted into the pressing tool part 4 of the open hot press. Since each pre-pressed piece - as is generally known - breathes after the pre-pressing, ie when the pre-press is opened due to springing back of the molding compound, the volume increases, the pre-pressed piece projects beyond the outer dimensions of the pressing tool part 4. If the pressing tool part 3 of the hot press is now lowered onto the pressing tool part 4 with the preform lying therein, then the inclined surface 7 presses the protruding parts of the preform continuously inwards without damaging the preform. For this purpose, the inclined surface 7 should have the smoothest possible surface. The height and the inclination of the inclined surface depend on the shape of the profile body and can be determined by simple tests if necessary.

Aus der Figur ist weiter zu erkennen, daß der Rand des inneren Preßwerkzeugteiles 4 eine hochgezogene, spitze Kante 9 besitzt. Diese Maßnahme unterstützt die Wirkung der schrägen Fläche 7 in folgender Weise :

  • Wenn sich das äußere Preßwerkzeugteil 3 auf das innere Preßwerkzeugteil 4 zu bewegt und den Vorpreßling nach innen drückt, hält die Kante einerseits den Vorpreßling fest und andererseits wird die Deckschicht gleichmäßig an die Kante des Vorpreßlings gelegt.
From the figure it can also be seen that the edge of the inner press tool part 4 has a raised, pointed edge 9. This measure supports the effect of the inclined surface 7 in the following way:
  • When the outer pressing tool part 3 moves towards the inner pressing tool part 4 and presses the pre-compact inwards, the edge holds the pre-compact on the one hand and on the other hand the cover layer is placed evenly on the edge of the pre-compact.

Weiterhin ist aus der Figur zu erkennen, daß bei der erfindungsgemäßen Presse der Rand des äußeren Preßwerkzeugteils 3 zwischen waagerechter Fläche 8 und der Außenkante einen Rücksprung 10 besitzt. Diese Maßnahme trägt in vorteilhafter Weise dazu bei, daß das Ankleben der überstehenden Teile der Deckschicht an dem äußeren Preßwerkzeugteil 3 verhindert und das Reinigen dieses Preßwerkzeugteiles wenigstens erleichtert wird, wenn es sich nicht sogar weitgehend erübrigt.Furthermore, it can be seen from the figure that in the press according to the invention the edge of the outer pressing tool part 3 has a recess 10 between the horizontal surface 8 and the outer edge. This measure advantageously contributes to the fact that the protruding parts of the cover layer are prevented from sticking to the outer pressing tool part 3 and the cleaning of this pressing tool part is at least made easier if it is not even largely unnecessary.

In der Figur ist die Presse derart ausgebildet, daß das innere Preßwerkzeugteil 4 feststehend und das äußere Preßwerkzeugteil 3 vertikal nach oben und unten verschiebbar angeordnet ist. Es ist aber im Prinzip gleichgültig, welches der Preßwerkzeugteile von oben her gegen das andere Preßwerkzeugteil auf die Preßmasse einwirkt. Es ist ebenso möglich, daß das innere Preßwerkzeugteil 4 nach oben verschiebbar ausgebildet oder oben angeordnet ist oder daß beide Preßwerkzeugteile gegeneinander verschiebbar angeordnet sind.In the figure, the press is designed such that the inner press tool part 4 is stationary and the outer press tool part 3 is arranged to be vertically displaceable up and down. In principle, however, it does not matter which of the pressing tool parts acts from above against the other pressing tool part on the molding compound. It is also possible that the inner press tool part 4 is designed to be displaceable upwards or arranged at the top, or that both press tool parts are arranged to be displaceable relative to one another.

Die Erfindung ist vorstehend anhand einer Presse beschrieben worden, bei der während des Heißpressens gleichzeitig das Aushärten des Kerns und das Aufbringen der Deckschicht erfolgt. Die neue Presse kann aber auch verwendet werden, wenn der Profilkörper nur heißgepreßt, d. h. ausgehärtet werden soll. Ebenso ist die neue Presse verwendbar, wenn das Heißpressen in zwei Stufen durchgeführt wird, wie dies von der bekannten Presse bekannt ist.The invention has been described above with reference to a press in which the core is cured and the cover layer is applied simultaneously during hot pressing. The new press can also be used if the profile body is only hot pressed, i.e. H. should be cured. The new press can also be used if the hot pressing is carried out in two stages, as is known from the known press.
