Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen heißvul­ kanisierter Verbindungen von Gummiprofilen mit einer die Profile aufnehmenden Form.The invention relates to a device for producing hot vol canized connections of rubber profiles with one of the profiles absorbing form.

Dichtungsrahmen großer Abmessungen, beispielsweise für Wehrbau­ ten, werden aus extrudierten oder aus extrudierten und formge­ preßten Gummiprofilen hergestellt. Die Verbindung der einzelnen Profilteile erfolgt entweder durch Kleben oder durch Heißvul­ kanisieren. Geklebte Verbindungen sind nur begrenzt gegen Wasser beständig und erreichen an der Stoßstelle Festigkeitswerte von lediglich etwa 50% des Profilwerkstoffs. Bei heißvulkanisierten Verbindungen wird dagegen etwa die Festigkeit des Gummiprofil­ werkstoffs erreicht. Erforderlich ist allerdings eine Form, in der die Gummiprofile aufgenommen und miteinander verbunden wer­ den. Die letztgenannte Verbindungstechnik ist daher besonders kostenaufwendig und kann vorwiegend nur fabrikmäßig ausgeführt werden.Sealing frames of large dimensions, for example for weir construction ten, are made from extruded or from extruded and molded pressed rubber profiles. The connection of the individual Profile parts are made either by gluing or by hot melt canise. Glued connections are only limited against water resistant and reach strength values of only about 50% of the profile material. For hot vulcanized Connections, on the other hand, is about the strength of the rubber profile material reached. However, a form is required in who picked up the rubber profiles and connected them together the. The latter connection technology is therefore special costly and can mainly only be carried out at the factory will.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Herstellen formgenauer, eine hohe Festigkeit aufweisender Ver­ bindungen von vorzugsweise extrudierten Gummiprofilen, insbeson­ dere für Wehrbauten, zu schaffen, die besonders für den Einsatz auf der Baustelle geeignet ist. The invention has for its object a device for Manufacture precise shape, high strength Ver Bindings of preferably extruded rubber profiles, in particular those for weir structures, to create that especially for use is suitable on the construction site.  

Diese Aufgabe wird durch die in Anspruch 1 gekennzeichneten Merkmale gelöst. Diese Lösung ist insofern vorteilhaft, als die Vorrichtung sich durch einfachen, kompakten Aufbau auszeichnet. Sie kann daher ohne Schwierigkeiten auf Baustellen eingesetzt werden, da zur Durchführung des Vulkanisationsvorganges als Wär­ mequelle Gas oder elektrischer Strom und für die Preßeinrichtung ein Druckmedium, z. B. Preßluft, benötig wird.This object is characterized by those in claim 1 Features solved. This solution is advantageous in that the Device is characterized by a simple, compact structure. It can therefore be used on construction sites without difficulty be, because to carry out the vulcanization process as heat mequelle gas or electric current and for the pressing device a print medium, e.g. B. compressed air, is required.

Die in Anspruch 2 zur Herstellung einer Eckverbindung angegebene Ausgestaltung hat den Zweck, die schwierige mechanische Bear­ beitung der Form im Bereich des Verbindungsstoßes zu verein­ fachen, indem dort der Querschnitt vergrößert ist. Der nach dem Vulkanisationsvorgang in diesem Bereich überstehende Gummi kann leicht mit einem Messer abgetrennt werden, um die Dichtfläche im Bereich des Verbindungsstoßes an diejenige der angrenzenden Gum­ miprofile anzugleichen.The specified in claim 2 for making a corner connection Design has the purpose of making the difficult mechanical bear processing of the shape in the area of the joint fold by increasing the cross section there. The one after Vulcanization process in this area can protrude rubber can be easily separated with a knife to the sealing surface in the Area of the connection joint to that of the adjacent gum align miprofile.

Die in Anspruch 3 angegebene Maßnahme verbessert und erleichtert die Beheizbarkeit der Form.The measure specified in claim 3 improved and facilitated the heatability of the mold.

In der Zeichnung ist ein Ausführungsbeispiel einer Vorrichtung zum Herstellen heißvulkanisiserter Verbindungen von Gummipro­ filen mit einer die Profile aufnehmenden Form dargestellt. Es zeigen:In the drawing is an embodiment of a device for the production of hot vulcanized compounds from Gummipro filen with a shape that accommodates the profiles. It demonstrate:

Fig. 3 eine Ansicht auf eine Stirnseite der Form in Richtung des Pfeiles III in Fig. 2 gesehen. Fig. 3 seen a view of an end face of the mold in the direction of arrow III in Fig. 2.

Die in Fig. 1 mit 10 bezeichnete Vorrichtung besteht im we­ sentlichen aus einer stählernen Form 11 mit rechtwinklig zu­ einander angeordneten Formschenkeln 12 und 13 (vergleiche Fig. 2). In die Formschenkel 12, 13 sind Ausnehmungen 14, 15 für die Aufnahme der Endabschnitte 16, 17 von Gummiprofilen 18, 19 ein­ gearbeitet. Im Verlauf der Ausnehmungen 14, 15 ist die Form 11 zweigeteilt, so daß der Querschnitt des Gummiprofils 18, 19 etwa mittig in der Trennfuge 20 der beiden Formteile 21 und 22 liegt (Fig. 3). Die beiden Formteile 21 und 22 sind mit Spannmitteln, z. B. Schrauben 23 im Bereich beider Formschenkel 12, 13 zusam­ mengehalten. Zusätzlich ist eine Zentrierung der beiden Form­ teile 21, 22 durch nicht dargestellte, formschlüssige Mittel vorgesehen.The device designated by 10 in FIG. 1 consists essentially of a steel form 11 with mutually perpendicular shaped legs 12 and 13 (see FIG. 2 ). In the shaped legs 12 , 13 recesses 14 , 15 for receiving the end portions 16 , 17 of rubber profiles 18 , 19 are worked. In the course of the recesses 14 , 15 , the shape 11 is divided into two, so that the cross section of the rubber profile 18 , 19 lies approximately centrally in the parting line 20 of the two shaped parts 21 and 22 ( FIG. 3). The two molded parts 21 and 22 are with clamping means, for. B. screws 23 in the area of both molded legs 12 , 13 together. In addition, a centering of the two mold parts 21 , 22 is provided by positive means, not shown.

Im Bereich der Stoßverbindung 24 der beiden Gummiprofile 18, 19 ist in der Form 11 eine schlitzförmige Aussparung 25 eingear­ beitet, welche sich im Querschnitt nach Fig. 2 mit rechteck­ förmigem Umriß darstellt. Durch diese Aussparung 25 erübrigt sich die schwierige Herstellung der aufeinandertreffenden Aus­ nehmungen 14 und 15 im Verbindungsstoß 24. Die Aussparung 25 geht zur Oberseite der Form 11 hin in eine Durchbrechung 26 über. Oben auf der Form 11 sitzt ein quaderförmiger Aufsatz 27, in dem sich die Durchbrechung 26 in Form einer Bohrung 28 fort­ setzt. Am quaderförmigen Aufsatz 27 ist ein Profilstab 29 als Stütze für einen über der Form 11 angeordneten pneumatischen Zylinder 30 angebracht. Dessen nach unten herausragende Kol­ benstange 31 trägt einen Kolben 32, der passend in die Bohrung 28 des Aufsatzes 27 einzugreifen vermag (strichpunktierte Linien in Fig. 1). Schließlich ist die Form im Bereich des Verbin­ dungsstoßes 24 mit Bohrungen 33 zur Aufnahme elektrischer Heiz­ patronen 34 ausgestattet.In the area of the butt joint 24 of the two rubber profiles 18 , 19 , a slit-shaped recess 25 is machined in the mold 11 , which is shown in the cross section according to FIG. 2 with a rectangular outline. Through this recess 25 , the difficult manufacture of the clashing recesses 14 and 15 in the connecting joint 24 is unnecessary. The recess 25 merges into an opening 26 toward the top of the mold 11 . On top of the mold 11 is a cuboid attachment 27 , in which the opening 26 continues in the form of a bore 28 . A profile rod 29 is attached to the cuboid attachment 27 as a support for a pneumatic cylinder 30 arranged above the mold 11 . Its downward protruding piston rod 31 carries a piston 32 which is able to fit into the bore 28 of the attachment 27 (dash-dotted lines in FIG. 1). Finally, the shape in the connec tion joint 24 with holes 33 for receiving electrical heating cartridges 34 is equipped.

Die Vorrichtung 10 wird in folgender Weise verwendet: The device 10 is used in the following way:

Die im Eckstoß miteinander zu verbindenden Gummiprofile 18, 19 werden endseitig unter einem Gehrungswinkel von 45° zu ihrer Längsachse abgetrennt. Gegebenenfalls werden die Schnittflächen zur Erhöhung der Festigkeit der Vulkanisationsverbindung vorbe­ handelt. Die Endabschnitte 16, 17 der beiden Gummiprofile 18, 19 werden in die geöffnete Form 11 eingelegt, so daß ihre Schnitt­ flächen etwa mit den Seitenflächen der Aussparung 25 fluchten. Anschließend wird die Form geschlossen und mit den Schrauben 23 zusammengespannt. Mittels der Heizpatronen 34 erfolgt nun die Erwärmung der Form 11 auf Vulkanisationstemperatur. In die Boh­ rung 28 des Aufsatzes 27 der Form 11 wird eine abgemessene Menge Gummirohmasse eingebracht. Nun wird der Kolben 32 des Zylinders 31 in die Bohrung 28 gefahren und die Gummirohmasse in die Aus­ sparung 25 gepreßt. Der Preßdruck wird während der von der Gum­ miqualität abhängigen Dauer des Vulkanisationsvorganges aufrecht erhalten. Hierdurch wird eine Blasenbildung im Verbindungsstoß 24 der Gummiprofile 18, 19 verhindert und der Wärmeübergang auf die Gummirohmasse sowie die Gummiprofile verbessert. Nach ab­ geschlossenem Vulkanisationsvorgang wird die Wärmezufuhr beendet und die Form 11 geöffnet. Die miteinander verbundenen Gummipro­ file 18, 19 werden aus der Form 11 entnommen und der Verbin­ dungsstoß 24 mit einem Messer dort nachgeschnitten, wo über­ schüssiger Gummi über die Dichtfläche hervorsteht.The rubber profiles 18 , 19 to be joined together in the corner joint are separated at the end at a miter angle of 45 ° to their longitudinal axis. If necessary, the cut surfaces are pre-treated to increase the strength of the vulcanization connection. The end portions 16 , 17 of the two rubber profiles 18 , 19 are inserted into the open mold 11 so that their cut surfaces are approximately flush with the side surfaces of the recess 25 . The mold is then closed and clamped together with the screws 23 . The heating cartridges 34 are now used to heat the mold 11 to the vulcanization temperature. In the drilling tion 28 of the top 27 of the mold 11 , a measured amount of rubber raw material is introduced. Now the piston 32 of the cylinder 31 is moved into the bore 28 and the raw rubber mass is pressed into the savings 25 . The pressing pressure is maintained during the duration of the vulcanization process, which depends on the rubber quality. This prevents the formation of bubbles in the connection joint 24 of the rubber profiles 18 , 19 and improves the heat transfer to the raw rubber mass and the rubber profiles. After the vulcanization process has ended, the heat supply is ended and the mold 11 is opened. The interconnected Gummipro file 18 , 19 are removed from the mold 11 and the connec tion joint 24 cut with a knife where protruding rubber over the sealing surface protrudes.
