Vorrichtung zur Herstellung eines rohrartigen Elements aus Silikongummi mit Textilverstärkung und damit hergestelltes rohrartiges ElementDevice for producing a tubular element made of textile-reinforced silicone rubber and tubular element produced thereby
BeschreibungDescription
Die Erfindung betrifft eine Vorrichtung zur Herstellung von rohrartigen Elementen aus Silikongummi mit Textilverstärkung, die beispielsweise als Luftauslassrohre für turbogeladene Verbrennungsmotoren für Kraftfahrzeuge verwendbar sind.The invention relates to a device for producing tubular elements made of textile-reinforced silicone rubber, which can be used, for example, as air outlet pipes for turbocharged internal combustion engines for motor vehicles.
Wegen der immer strengeren Anforderungen, unbenutzten Platz im Motorraum zu verkleinern, müssen Luftauslassrohre für turbogeladene Kraftfahrzeugmotoren in der Lage sein, sehr hohen Arbeitstemperaturen in der Größenordnung von 250 0C zu widerstehen.Due to increasingly stringent requirements to reduce unused space in the engine compartment, air outlet pipes for turbocharged automotive engines must be able to withstand very high operating temperatures in the order of 250 0 C.
Herkömmliche Schläuche oder Rohre, die aus elastomerem Material, wie etwa EPDM, hergestellt sind, sind nicht geeignet, solchen hohen Temperaturen zu widerstehen.Conventional hoses or pipes made of elastomeric material such as EPDM are not suitable for withstanding such high temperatures.
In jüngster Zeit wurden daher Rohre verwendet, die aus Textilgeweben hergestellt waren, die mit Silikongummi imprägniert und zur Bildung von rohrartigen Elementen aufgerollt wurden, die dann, sobald sie an Formelementen angeordnet wurden, um ihnen die gewünschte Form zu geben, vulkanisiert wurden.Recently, therefore, tubes have been used made of textile fabrics impregnated with silicone rubber and rolled up to form tubular elements which, once arranged on molded elements, were then vulcanized to give them the desired shape.
Dieses Verfahren, rohrartige Elemente aus Silikongummi mit Textilverstärkung herzustellen, ist außerordentlich teuer, da es ein fast vollständig manuelles Herstellungsverfahren ist.This process of producing tubular elements made of silicone rubber with textile reinforcement is extremely expensive because it is an almost entirely manual manufacturing process.
Aufgabe der Erfindung ist es daher, eine Vorrichtung anzugeben, die es ermöglicht, die oben erwähnten rohrartigen Produkte aus Silikongummi mitThe object of the invention is therefore to provide a device which makes it possible to use the above-mentioned tubular products made of silicone rubber with
Textilverstärkung ökonomisch und technisch einfacher, insbesondere automatisiert, herzustellen, sowie ein damit hergestelltes Produkt.Textile reinforcement can be produced more economically and technically, especially in an automated manner, as well as a product manufactured therewith.
Diese und andere Aufgaben werden erfindungsgemäß durch die in Anspruch 1 angegebene Vorrichtung bzw. ein Produkt nach Anpsruch 6 oder 7 gelöst.These and other objects are achieved according to the invention by the device specified in claim 1 or a product according to claim 6 or 7.
Weitere Merkmale und Vorteile der Erfindung werden aus der folgenden detaillierten Beschreibung, die nur ein nicht einschränkendes Beispiel angibt, anhand der beigefügten Zeichnungen ersichtlich. Hierin ist:Further characteristics and advantages of the invention will become apparent from the following detailed description, given only as a non-limiting example, with reference to the accompanying drawings, in which:
Figur 1 eine schematische Darstellung einer erfindungsgemäßen Vorrichtung oder Anlage für die Herstellung von rohrartigen Elementen von oben betrachtet,Figure 1 is a schematic representation of a device or system according to the invention for the production of tubular elements viewed from above,
Figur 2 eine Seitenansicht eines Teils der Vorrichtung oder Anlage von Figur 1;Figure 2 is a side view of part of the device or installation of Figure 1;
Figuren 3 bis 6 Schnitte entlang den Linien MI-III bis Vl-Vl von Figur 2; undFigures 3 to 6 are sections along the lines MI-III to VI-VI of Figure 2; and
Figur 7 ein Querschnitt eines rohrartigen Produkts aus Silikongummi mit Textilverstärkung, das erfindungsgemäß hergestellt ist.Figure 7 is a cross-section of a tubular product made of textile-reinforced silicone rubber, manufactured according to the invention.
In Bezug auf die Figuren 1 und 2 umfasst eine Anlage für die Herstellung von rohrartigen Produkten aus Silikongummi mit Textilverstärkung erfindungsgemäß eine Mehrzahl von nacheinander angeordneten Stationen.With reference to Figures 1 and 2, a plant for the production of tubular products made of silicone rubber with textile reinforcement comprises according to the invention a plurality of stations arranged one after the other.
In einer Zufuhrstation 1 ist an einem Tragrahmen 2 eine Rolle 3 um eine im Wesentlichen horizontale Achse drehbar gelagert. Ein Längsabschnitt eines rohrartigen Trägerelements 4, das beispielsweise aus einem vulkanisierten elastomeren Material, wie etwa EPDM, hergestellt ist, ist auf die Rolle 3 gewickelt. Dieses rohrartige Trägerelement besitzt ein Ende 4a (Figur 2),In a feed station 1, a roller 3 is mounted on a support frame 2 so as to be rotatable about a substantially horizontal axis. A longitudinal section of a tubular carrier element 4, which is made, for example, from a vulcanized elastomeric material such as EPDM, is wound onto the roller 3. This tubular carrier element has an end 4a (Figure 2),
das in der Nähe der Drehachse der Rolle 3 gehalten wird und, wie später erläutert, dazu dient, bei Betrieb mit einer Vorrichtung (nicht gezeigt) verbunden zu werden, um einen gasartigen Fluidstrom, insbesondere Luft, in das rohrartige Trägerelement 4 zu blasen.which is held near the axis of rotation of the roller 3 and, as explained later, serves to be connected in operation to a device (not shown) for blowing a gaseous fluid stream, in particular air, into the tubular support element 4.
Stromab der Zufuhrstation 4 befindet sich eine erste Extrusionsstation 5 bekannter Bauart. Diese Extrusionsstation umfasst (Figur 2) einen Extrusionkopf 6, durch den das rohrartige Trägerelement 4 hindurchtritt und in dem eine erste ringartige Schicht aus "Rohmaterial", d.h. nicht vulkanisiertem Silikongummi, in Figur 4 mit 7 bezeichnet, auf die Außenoberfläche des rohrartigen Trägerelements 4 aufextrudiert wird.Downstream of the feed station 4 there is a first extrusion station 5 of known design. This extrusion station comprises (Figure 2) an extrusion head 6 through which the tubular support element 4 passes and in which a first ring-like layer of "raw material", i.e. unvulcanized silicone rubber, designated 7 in Figure 4, is extruded onto the outer surface of the tubular support element 4.
Das halbfertige rohrartige Produkt 8, das aus dem Extrusionskopf 6 austritt, erreicht eine Gitterbildungsstation, in den Figuren 1 und 2 mit 19 bezeichnet. In dieser Station wird ein rohrartiges Textil-"Geflecht" oder Gitter, in Figur 5 mit 9 bezeichnet, auf das halbfertige Produkt 8 geformt.The semi-finished tubular product 8 emerging from the extrusion head 6 reaches a grid forming station, designated 19 in Figures 1 and 2. In this station a tubular textile "mesh" or grid, designated 9 in Figure 5, is formed on the semi-finished product 8.
Das rohrartige Produkt 10, das aus der Gitterbildungsstation 19 austritt, läuft durch eine Ziehstation 11 (Figuren 1 und 2) und erreicht dann eine zweite Extrusionsstation 12.The tubular product 10 exiting the grid forming station 19 passes through a drawing station 11 (Figures 1 and 2) and then reaches a second extrusion station 12.
Eine zweite ringartige Schicht aus Silikongummi, in Figur 6 mit 11 bezeichnet, wird in der Extrusionsstation 12 auf das halbfertige Produkt 10 extrudiert. Diese zweite Silikongummischicht 11 bindet perfekt mit der darunterliegenden Schicht 7 durch die Gitter des Geflechts 9.A second ring-like layer of silicone rubber, designated 11 in Figure 6, is extruded onto the semi-finished product 10 in the extrusion station 12. This second silicone rubber layer 11 bonds perfectly with the underlying layer 7 through the grids of the braid 9.
Das halbfertige Produkt 13, das aus der zweiten Extrusionsstation 12 austritt, läuft dann durch ein Kühlbad, in Figur 1 mit 14 bezeichnet.The semi-finished product 13 exiting the second extrusion station 12 then passes through a cooling bath, designated 14 in Figure 1.
Stromab des Kühlbads 14 erreicht das Produkt 13 eine Station 15, um das Produkt 13 auf Länge zu schneiden (Figur 1), worin das Produkt 13 in eineDownstream of the cooling bath 14, the product 13 reaches a station 15 to cut the product 13 to length (Figure 1), wherein the product 13 is cut into a

Auf in den Zeichnungen nicht gezeigter Weise werden die Abschnitte des halbfertigen Produkts 13 zu einer nachfolgenden Ablagerungsstation überführt.In a manner not shown in the drawings, the sections of the semi-finished product 13 are transferred to a subsequent deposition station.
Nach Abschluss der Ablagerungsstufe wird das rohrartige Trägerelement 4 von jedem Abschnitt des halbfertigen Produkts 13 abgenommen. Man erhält somit einen Abschnitt eines halbfertigen Produkts, wie es etwa in Figur 7 mit 16 bezeichnet ist, im Wesentlichen gebildet durch ein rohrartiges Silikongummielement, in das ein rohrartiges Textilgitter oder geflecht 9 eingebaut ist.After completion of the deposition stage, the tubular support element 4 is removed from each section of the semi-finished product 13. A section of a semi-finished product is thus obtained, such as that indicated at 16 in Figure 7, essentially formed by a tubular silicone rubber element in which a tubular textile grid or braid 9 is incorporated.
Die Abschnitte des halbfertigen Produkts 16 werden dann auf Formelemente bekannten Typs aufgesetzt, um diesen eine gewünschte Form zu verleihen, und sie werden dann einer Vulkanisierung unterzogen.The sections of the semi-finished product 16 are then placed on mold elements of known type to give them a desired shape and they are then subjected to vulcanization.
Nach der Vulkanisierung können die rohrartigen Elemente aus verstärktem Silikongummi von den Formelementen abgenommen werden und sind dann gebrauchsfertig.After vulcanization, the tubular elements made of reinforced silicone rubber can be removed from the mold elements and are then ready for use.
Um das Abnehmen des rohrartigen Trägerelements 4 von dem umgebenden rohrartigen Silikongummielement zu erleichtern, ist die Außenfläche des rohrartigen Trägerelements 4 bevorzugt mit einem Film aus Antihaftmaterial versehen, beispielsweise Talkum.In order to facilitate the removal of the tubular support element 4 from the surrounding tubular silicone rubber element, the outer surface of the tubular support element 4 is preferably provided with a film of non-stick material, for example talc.
Während das Prinzip der Erfindung das gleiche bleibt, können natürlich die Formen der Ausführungen und Konstruktionsdetails in Bezug auf jene, die lediglich als nicht einschränkendes Beispiel bschrieben und illustriert wurden, weit geändert werden, ohne vom Umfang der Erfindung abzuweichen, wie er in den beigefügten Ansprüchen definiert ist.While the principle of the invention remains the same, the forms of embodiment and construction details may of course be widely varied with respect to those described and illustrated merely by way of non-limiting example, without departing from the scope of the invention as defined in the appended claims.
