Description

Geteilte Form zum Herstellen endloser Keilriemen Die Erfindung betrifft eine geteilte Form zum Herstellen endloser Keilriemen, insbesondere für Ventilatoren.Split mold for making endless V-belts The invention relates to a split mold for making endless V-belts, especially for fans.

Bei dem Herstellen endloser Keilriemen bedient man sich zum Aufbau des Riemens einer geteilten Form, in der der Riemen aufgebaut wird. Der Faserstoff wird in einem besonderen Tränkkessel mit Kautschukmilch unter Druck ge.ränkt. Um eine nachträgliche Dehnung des Riemens zu verhindern, werden die Fasern während das Herstellungsvorgan ges gestreckt. Die Streckung erfolgt auf einem Dorn. konischen Formen oder ähnlichen, eine Streckung des Vor- und Halbfertigerzeugnisses ermöglichenden Einrichzungen. Die Herstellung eines derartigen Riemens ist indessen langwierig, da das Tränken des Faserstoffes mit Rautschulimilell unter Druck in den bisher bekannten Formen nicht möglich ist, sondern in einem Tränkkessel erfolgen muß. When producing endless V-belts, one uses oneself for the construction of the belt of a split form in which the belt is constructed. The fiber is impregnated with rubber milk under pressure in a special soaking kettle. Around To prevent subsequent stretching of the belt, the fibers are used during the manufacturing process stretched. The stretching takes place on a mandrel. conical Shapes or similar that allow stretching of the semi-finished and semi-finished product Facilities. The production of such a belt is tedious, however, because the impregnation of the pulp with Rautschulimilell under pressure in the previously known Forming is not possible, but must be done in a soaking kettle.

Um nun das Tränken der Fasern in der Aufbauform zu ermöglichen, ist die geteilte Form erfindungsgemäß derart ausgebi.det, daß ein kreisringförmiger Deckel mit Anschlüssen zum Entlüften der Form sowie zum Einfüllen der Kautschukmilch die aus zwei Scheiben bestehende Aufbauform umschließt. In order to enable the impregnation of the fibers in the structure, is the divided shape according to the invention developed in such a way that a circular ring-shaped Lid with connections for venting the mold and for filling in the rubber milk encloses the structure consisting of two panes.

In der Zeichnung ist die Form gemäß der Erfindung beispielsweise dargestellt. In the drawing, the shape according to the invention is for example shown.

Die Form besteht aus den beiden scheibenförmigen Teilen i und 2, die durch Bolzen 3 o. dgl. zusammengehalten werden, so daß der Faserstoff in die keilförmige Nut 4 aufgespult werden kann. Danach wird die Form durch den Deckel 5 verschlossen und zur Abdichtung der Form diese unter einer Presse 0. dgl. eingespannt. Zur Erzielung eines vollkommen dichten Abschlusses der geteilten Form ist der Deckel 5 an seinen Dichtflächen vorteilhaft aufgeschliffen und gegebenenfalls mit Dicht tungseinrichtungen ausgestattet. Er ist an seinem oberen Ende wie dies bei g dargestellt ist, auf die Scheibe 2 aufgezogen, so daß durch den Druck der Einspannvorrichtung ein festes Anliegen des Deckels 5 an seinen Abdichtflächen erzielt wird. Der Deckel 5 weist an seinem Umfange Anschlüsse 6 und 7 auf, durch die der Hohlraum 8 an Saug- und Druckleitungen angeschlossen werden kann. The shape consists of the two disc-shaped parts i and 2, which are held together by bolts 3 o. The like. So that the fiber in the wedge-shaped groove 4 can be wound. After that, the shape is through the lid 5 closed and to seal the form it is clamped under a press 0. To achieve a completely tight closure of the divided form, the lid 5 advantageously ground on its sealing surfaces and optionally with sealing equipment. It is shown at its upper end as shown at g is drawn onto the disc 2, so that by the pressure of the clamping device a firm fit of the cover 5 is achieved on its sealing surfaces. The lid 5 has connections 6 and 7 on its circumference, through which the cavity 8 to suction and pressure lines can be connected.

Nachdem der Faserstoff aufgespult und die Form geschlossen ist, wird durch einen der Anschlüsse die im Hohlraum zwischen den Fasern des Gewebes eingeschlossene Luft ausgepumpt. Nachdem ein ausreichender Grad der Lufiverdünnung e.rei h. it wird der eine Anschluß verschlossen und nunmehr in an sich bekannter Weise durch den anderen Anschluß Kautschukmilch unter hohem Druck in die Form gepreßt. Nach ausreichender Tränkung der aufgespulten Fäden mit Kautschukmilch wird der Druck abgelassen und der Riemen nach Auseinandernehmen der Tränkform von dieser abgenommen und in üblicher Weise vulkanisiert. After the pulp is wound up and the mold is closed, it is through one of the connections, the one enclosed in the cavity between the fibers of the tissue Air pumped out. After a sufficient degree of air dilution e.rei h. it will the one connection closed and now in a known manner by the other connection rubber milk is pressed into the mold under high pressure. After sufficient Soaking the wound threads with rubber milk, the pressure is released and the belt after dismantling the impregnation mold removed from it and in the usual way Way vulcanized.
