Description
Verfahren zur Herstellung von durchlöcherten Kautschukrohren Es ist bekannt, Rohre oder Schläuche aus unvulkanisierten Kautschukbändern mit Hilfe von gerillten Walzen herzustellen. Bei diesem Herstellungsverfahren wird durch die Rillen zweier übereinander angeordneter Walzen ein Kern zugleich mit zwei Gummibändern hindurchgeführt. Die Gummibänder werden durch die Innenwandung der Rillen über dem Kern zusammengebogen und längs ihrer Ränder zusammengedrückt. Dieses Verfahren ist . zur Herstellung durchlöcherter Rohre oder Schläuche aus entsprechend durchlöcherten unv ulkanisierten Kautschukbändern nicht anwendbar, weil die Bänder durch die Rilleninnenwandungen mit verhältnismäßig starker Pressung gegen den Kern gedrückt werden und hierbei etwa in dem weichen Bandmaterial vorhandene Löcher zugedrückt werden würden.Method of making perforated rubber pipes It is known pipes or hoses made of unvulcanized rubber tapes with the help of to manufacture grooved rollers. In this manufacturing process, the grooves two rollers arranged one above the other, a core at the same time with two rubber bands passed through. The rubber bands are through the inside wall of the grooves above the Core bent together and compressed along its edges. This procedure is . for the production of perforated pipes or hoses from appropriately perforated unvulcanized rubber bands cannot be used because the bands pass through the inner walls of the grooves are pressed with relatively strong pressure against the core and this for example, existing holes in the soft band material would be closed.
Es hat sich nun herausgestellt, daß die Herstellung durchlöcherter Rohre oder Schläuche aus durchlöcherten Kautschukbändern mit Hilfe von Rillenwalzenpaaren dann ohne weiteres möglich ist, wenn von der Verwendung des Kernes abgesehen wird. Die durchlöcherten Bänder werden in an sich bekannter Weise durch die Rillen mindestens eines rotierenden Walzenpaares bei ihrem Durchgang zwischen den Walzen hindurch zusammengebogen und längs ihrer Ränder durch die Kanten der Rillen miteinander vereinigt. Dadurch, daß sich innerhalb der Bänder kein Kern befindet, kann auch von der Rilleninnenwandung der Walzen kein die Löcher verstopfender Druck auf die Bandoberfläche ausgeübt werden.It has now been found that the production of perforated Pipes or hoses made from perforated rubber strips with the help of pairs of grooved rollers is then easily possible if the use of the core is dispensed with. The perforated bands are in a manner known per se through the grooves at least a rotating pair of rollers as they pass between the rollers bent together and united along their edges by the edges of the grooves. The fact that there is no core inside the strips can also be removed from the inner wall of the groove the rollers do not exert any pressure on the surface of the belt which would block the holes.
Bei Anwendung des Verfahrens gemäß der Erfindung können in dem gleichen Arbeitsgang, in dem die Bänder zu Rohren gebogen und miteinander verbunden werden, Rippen o. dgl. an der Verbindungsstelle der Bänder angepreßt werden, so daß Rippenrohre erzeugt werden.When applying the method according to the invention can in the same Operation in which the strips are bent into tubes and connected to one another, Ribs o. The like. Are pressed at the connection point of the bands, so that finned tubes be generated.
Die unvulkanisierten Gummibänder können sowohl aus Weichgummi- als auch aus Hartgummimischung von genügender Steifheit bestehen. Besonders zweckmäßig ist die Anwendung der Erfindung für die Herstellung durchlöcherter Hartgummirohre, wie diese beispielsweise bei elektrischen Akkumulatoren verwendet werden.The unvulcanized rubber bands can be made of both soft rubber and also consist of a hard rubber mixture of sufficient rigidity. Particularly useful is the application of the invention for the production of perforated hard rubber pipes, how these are used, for example, in electrical accumulators.
Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht, und zwar stellt Fig. i zwei zur Durchführung des Verfahrens gemäß der Erfindung vorteilhafte Walzen in Ansicht von vorn dar, während Fig.2 eine abgeänderte Ausführungsform der Walzen veranschaulicht.The invention is illustrated in the drawing, for example, namely, Fig. i shows two for carrying out the method according to the invention advantageous rollers in a view from the front, while FIG. 2 shows a modified embodiment the rollers illustrated.
Die in der Zeichnung dargestellte Einrichtung zur Durchführung des Verfahrens umfaßt zwei Metallzylinder A, B, welche übereinander angeordnet sind und um ihre Achsen drehbar sind. Auf der Oberfläche der Zylinder sind Rillen C vorgesehen, die im Querschnitt halbkreisförmig oder ähnlich gestaltet sind. Die Kanten D der Einschnitte C sind als scharfe Kanten ausgebildet. Das Verfahren gemäß der Erfindung wird nun derart ausgeführt, daß zwei unvulkanisierte Gummibänder ohne Verwendung eines Kernes zwischen die Walzen A, B eingeführt, beim Durchgang durch das Walzwerk in gekrümmte Streifen umgewandelt und hierbei von den scharfen Kanten D auf die richtige Breite zugeschnitten, durch die Innenwandung der Rillen zusammengebogen und durch die" Schneidkanten D auch miteinander verbunden werden. Bei Benutzung eines Rillenquerschnittes gemäß Fig.2 läßt sich auch ein Rohr oder ein Schlauch, der mit Längsrippen versehen ist, in dem gleichen Arbeitsgange erzeugen, wie dies aus Fig. 2 ohne weiteres ersichtlich ist.The device shown in the drawing for carrying out the method comprises two metal cylinders A, B, which are arranged one above the other and are rotatable about their axes. On the surface of the cylinder, grooves C are provided which are semicircular or similar in cross section. The edges D of the incisions C are designed as sharp edges. The method according to the invention is now carried out in such a way that two unvulcanized rubber bands are inserted between the rollers A, B without the use of a core, converted into curved strips as they pass through the rolling mill and cut to the correct width by the sharp edges D by the Inner wall of the grooves are bent together and also connected to one another by the "cutting edges D. When using a groove cross-section according to FIG is readily apparent.
Um zu vermeiden, daß die zwei miteinander zu verbindenden Bänder außerhalb ihrer Ränder aneinanderhaften, kann man die Oberfläche der Bänder mit einem üblichen Pudermittel bestreuen, das die Verbindung der Bänder im rohen Zustande, aber nicht während der Vulkanisation verhindert. Bei Anwendung dieser Maßnahme bleiben die Bänder nur an ihren Rändern miteinander vereinigt, und zwar unter der Wirkung des mechanischen Druckes und ihrer Randv erschweißung, welche dann durch die Vulkanisation weiter gesichert wird. Man erhält auf die genannte Weise einen flachen Schlauch, der auf einen Kern von zylindrischer, elliptischer oder sonstiger Querschnittsform aufgezogen und dann vulkanisiert werden kann.In order to avoid that the two bands to be joined together are outside If their edges stick together, you can see the surface of the tapes with a usual Sprinkle with powder, but not the connection of the ligaments in the raw state prevented during vulcanization. When this measure is applied, the Ribbons united only at their edges, under the action of the mechanical pressure and its edge welding, which is then caused by vulcanization is further secured. In this way a flat tube is obtained, on a core of cylindrical, elliptical or other cross-sectional shape can be drawn up and then vulcanized.
" Die in Fig. 2 dargestellte Querschnittsform ist insbesondere für die Herstellung von durchlöcherten Hartgummirohren, die durch seitliche Rippen versteift sind, anwendbar. Auch können ohne weiteres noch andere Querschnittsformen je nach den Erfordernissen benutzt werden. Die nach dem l:aschriebenen Verfahren hergestellten Rohre werden in beliebiger Weise vulkanisiert."The cross-sectional shape shown in Fig. 2 is particularly for the production of perforated hard rubber pipes stiffened by ribs on the sides are applicable. Other cross-sectional shapes can also be used, depending on used as required. Those manufactured according to the procedure outlined above Pipes are vulcanized in any way.
Wenn Verstärkungsrippen vorgesehen sind, so sollen diese bei dem Verfahren gemäß der Erfindung geradliniger verlaufen als bei dem bekannten Spritzverfahren.. Dabei ist das Herstellungsverfahren billiger, zumal da man mehrere Rohre gleichzeitig herstellen kann. Durch das "Verfahren gemäß der Erfindung läBt sich eine sehr hohe Produktion erzielen, da die Einrichtungen, die die Erfindung durchführen, mit großer Geschwindigkeit arbeiten können. Die Lohnkosten, die mit dem Verfahren gemäß der Erfindung verbunden sind, sind gering. Ferner läßt sich durch das Verfahren gemäß der Erfindung der äußere Rohrdurchmesser sehr genau einhalten.If reinforcement ribs are provided, these should be used in the process according to the invention run more straight than in the known spraying process .. The manufacturing process is cheaper, especially since you have several pipes at the same time can produce. With the method according to the invention, a very high level can be achieved Achieve production because the facilities that carry out the invention with great Speed can work. The labor costs incurred with the procedure according to the Invention connected are low. Furthermore, by the method according to comply with the invention of the outer pipe diameter very precisely.
