Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Aufbringen einer Flächenpressung auf fortschreitende Werkstücke, wie Holzwerkstoffplatten o.dgl., bei der mindestens ein umlaufendes Preßband an das Werkstück von einem in eine Druckkammer einleitbaren Druckmittel anpreßbar ist und die Druckkammer durch einen Teil eines Trums des Preßbandes an der dem Trum gegenüberliegenden Seite durch eine rechteckförmige Druckplatte und an den in bezug auf die Laufrichtung des Preßbandes Längs- und Querrändern der Druckplatte durch eine am Rand der Druckplatte vorgesehene, sich am Preßband abstützende Dichtungsleiste aus Kunststoff oder dergleichen begrenzt ist.The invention relates to a device for applying surface pressure to progressive workpieces, such as wood-based panels or the like, in which at least one rotating press belt can be pressed against the workpiece by a pressure medium that can be introduced into a pressure chamber, and the pressure chamber through part of a run of the press belt is delimited on the side opposite the run by a rectangular pressure plate and on the longitudinal and transverse edges of the pressure plate with respect to the running direction of the press belt by a sealing strip made of plastic or the like provided on the edge of the pressure plate and supported on the press belt.
Es ist eine Vorrichtung dieser Art bekannt (DE-PS 33 13 406), bei der die Dichtungsleiste mit einem rechteckförmigen Fassungsrahmen verbunden ist, der in einer Nut der Druckplatte geführt, nuteinwärts und nutauswärts beweglich gelagert und in Richtung auf das an der Dichtungsleiste entlanggleitend angeordnete Preßband druckbelastet ist.A device of this type is known (DE-PS 33 13 406), in which the sealing strip is connected to a rectangular mounting frame which is guided in a groove of the pressure plate, movably mounted inwards and outwards, and in the direction of that which slides along the sealing strip Press belt is under pressure.
Bei den Fluidkissen-gestützten Doppelbandpressen übernehmen die Dichtungsleisten im Zusammenwirken mit aus Stahl gefertigten Preßbändern die Aufgabe, die Druckkammer gegen die Atmosphäre abzudichten.In the case of the fluid cushion-supported double belt presses, the sealing strips, in cooperation with press belts made of steel, take on the task of sealing the pressure chamber from the atmosphere.
An diese Dichtungen werden hohe Anforderungen gestellt, da in allen Betriebszuständen der kontinuierlich arbeitenden Presse eine zuverlässige Abdichtung der Druckkammer erreicht werden muß. Die Kunststoffleisten müssen gegenüber dem mit hohen und niedrigen Geschwindigkeiten umlaufenden Preßband über den gesamten Geschwindigkeitsbereich eine geringe Reibung entwickeln. Hinzu kommen muß eine geringe Erwärmung in einem großen Temperaturbereich und eine hohe Lebensdauer.High demands are placed on these seals, since they are reliable in all operating states of the continuously operating press Sealing of the pressure chamber must be achieved. The plastic strips have to develop low friction over the entire speed range compared to the press belt rotating at high and low speeds. In addition, there must be little heating in a wide temperature range and a long service life.
Als Werkstoff für derartige Dichtungsleisten werden gleitfreudige und temperaturbeständige Kunststoffe eingesetzt.Sliding and temperature-resistant plastics are used as the material for such sealing strips.
Um die genannten Anforderungen besser zu erfüllen ist es bekannt (EP-B-0 166 886) die Dichtungsleisten mit im Abstand voneinander angeordneten Schmierdüsen oder Schmierkanälen zu versehen, durch die Schmierflüssigkeit unmittelbar an die Dichtfläche transportiert wird.In order to better meet the above-mentioned requirements, it is known (EP-B-0 166 886) to provide the sealing strips with lubricating nozzles or lubrication channels which are arranged at a distance from one another and through which lubricating fluid is transported directly to the sealing surface.
Die so geschmierten Dichtungen arbeiten bis zu mittleren Flächendrücken zufriedenstellend. Bei höheren Drücken wird jedoch der Schmierfilm zu schnell aus der Dichtfuge herausgepreßt. Ein weiterer Nachteil besteht in dem verhältnismäßig hohen Kilogrammpreis der für den Einsatz benötigten Spezialöle.The seals lubricated in this way work satisfactorily up to medium surface pressures. At higher pressures, however, the lubricating film is pressed out of the sealing joint too quickly. Another disadvantage is the relatively high price per kilogram of the special oils required for the application.
Es sind ferner selbstschmierende Gleitelemente in Form von Lagerbuchsen und Platten bekannt, bei denen Festschmierstoffe in eine Metallmatrix eingelagert werden. Diese Gleitelemente sind als Dichtungen für Druckkammern von Bandpressen nicht geeignet. Unter der hohen Druck- und Temperaturbelastung werden insbesondere bei niedrigen Bandschwindigkeiten Metallpartikel herausgerissen, die zum Fressen, zur Kaltaufschweißung und damit zur Beschädigung der empfindlichen Stahlbandoberfläche führen.Self-lubricating sliding elements in the form of bearing bushes and plates are also known, in which solid lubricants are embedded in a metal matrix. These sliding elements are not suitable as seals for pressure chambers of belt presses. Under the high pressure and temperature load, metal particles are torn out, particularly at low belt speeds, which lead to seizure, cold welding and thus damage to the sensitive steel belt surface.
Der Erfindung liegt die Aufgabe zugrunde, in einer Vorrichtung der eingangs genannten Art die hochbelasteten Gleitflächendichtungen so zu gestalten, daß die aufgezeigten Anforderungen besser erfüllt und die Einsatzgebiete in bezug auf Druck, Temperatur und Bandgeschwindigkeit ausgedehnt werden können.The invention has for its object to design the highly stressed sliding surface seals in a device of the type mentioned in such a way that the specified requirements are better met and the areas of use can be expanded with respect to pressure, temperature and belt speed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in die Dichtungsstreifen aus Kunststoff im Abstand voneinander angeordnete, aus einem Festschmierstoff gefertigte, kompakte Formkörper eingebettet sind, die sich mit einer frei liegenden Arbeitsfläche am zugeordneten Trum des Preßbandes abstützen.This object is achieved in that in the sealing strips made of plastic, spaced apart, made of a solid lubricant, compact molded bodies are embedded, which are supported with an exposed work surface on the associated strand of the press belt.
Diese dauerhaft eingebetteten Formkörper aus einem Festschmierstoff nutzen sich in gleichem Maße wie der eigentliche Dichtungswerkstoff ab.These permanently embedded molded parts made of a solid lubricant wear out to the same extent as the actual sealing material.
Es wurde überraschend gefunden, daß das bei der Herstellung von Kunststoffen mögliche Einsintern von "kleinen" Festschmierstoffpartikeln in den Grundwerkstoff der Dichtung die Standzeit der Dichtung stark reduziert, während beim Einbetten von verhältnismäßig großen Formkörpern aus einem Festschmierstoff der Abrieb der Dichtung vermindert und die Lebensdauer erhöht wird.It has surprisingly been found that the possible sintering of "small" solid lubricant particles into the base material of the seal in the manufacture of plastics greatly reduces the service life of the seal, while embedding relatively large moldings from a solid lubricant reduces the abrasion of the seal and increases the service life becomes.
Bei einer vorteilhaften Ausführungsform der Erfindung entspricht die Bauhöhe der eingebetteten Festschmierstoffformkörper der Bauhöhe der Verschleißschicht der Kunststoffdichtungsleisten.In an advantageous embodiment of the invention, the height of the embedded solid lubricant moldings corresponds to the height of the wear layer of the plastic sealing strips.
Die Formkörper aus einem Festschmierstoff können sowohl in den die Querränder als auch in den die Längsränder der Druckkammer begrenzenden Kunststoffleisten angeordnet sein.The molded bodies made of a solid lubricant can be arranged both in the plastic strips delimiting the transverse edges and in the longitudinal edges of the pressure chamber.
Eine Verbesserung der Standzeit der Dichtung der Druckkammer kann auch dadurch schon erreicht werden, daß die parallel zur Förderrichtung des Preßbandes sich erstreckenden Dichtungsleisten mit den Festschmierstofformkörpern ausgerüstet sind.An improvement in the service life of the seal of the pressure chamber can also be achieved in that the sealing strips which extend parallel to the conveying direction of the press belt are equipped with the solid lubricant moldings.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.
