Description
Die Erfindung betrifft eine Pressvorrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a pressing device according to the preamble of
Pressvorrichtungen in Form von Presszangen werden hauptsächlich in der Sanitärinstallation eingesetzt, um Rohre oder Rohrstücke über Verbindungsstücke, sogenannte Fittings, miteinander zu verbinden. Die Verbindungsstücke werden über die Enden zweier Rohre geschoben und radial plastisch verformt, um eine feste und dichte Verbindung zwischen den beiden Rohren über das Verbindungsstück zu erreichen. Die Presszangen haben hierfür zwei Pressbacken mit jeweils eingearbeiteter systemspezifischer Presskontur. Häufig müssen solche Verpressungen an Stellen vorgenommen werden, die mit der Presszange nur schwierig zu erreichen sind.Pressing devices in the form of pressing tongs are mainly used in the sanitary installation to connect pipes or pipe sections via fittings, so-called fittings. The connectors are slid over the ends of two tubes and radially plastically deformed to achieve a tight and tight connection between the two tubes via the connector. The pressing tongs have two press jaws for this purpose, each with an integrated system-specific press contour. Often such compression must be made in places that are difficult to achieve with the crimping pliers.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Pressvorrichtung so auszubilden, dass mit ihr auch Verpressungen in Bereichen durchgeführt werden können, die schwierig zu erreichen sind.The invention has the object of providing the generic pressing device in such a way that it can be performed with compressions in areas that are difficult to achieve.
Diese Aufgabe wird bei der gattungsgemäßen Pressvorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention in the generic pressing device with the characterizing features of
Die erfindungsgemäße Pressvorrichtung zeichnet sich dadurch aus, dass die Achse der Aufnahme, welche die zu verpressenden Teile aufnimmt, unter einem von 90° abweichenden Winkel zur Quermittelebene der Pressbacken liegt. Bei herkömmlichen Pressvorrichtungen liegt die Achse der Aufnahme senkrecht zur Quermittelebene, wodurch es häufig nicht oder nur mit Mühe möglich ist, die zu verpressenden Teile zu erreichen. Infolge der schräg liegenden Aufnahme der erfindungsgemäßen Pressvorrichtung ist es nunmehr möglich, die Pressvorrichtung auch in schwierig zugänglichen Bereichen einzusetzen, um dort Verpressungen durchzuführen. Solche beengten Bereiche sind beispielsweise Raumecken, in denen die zu verpressenden Verbindungsstücke nahe benachbart zu einer Raumwand angeordnet sind. Infolge der Schräglage der Aufnahme kann die Pressvorrichtung in solchen Fällen so angesetzt werden, dass die Pressbacken schräg zur Wand verlaufen, so dass sie einfach mit einer Antriebsvorrichtung betätigt werden können.The pressing device according to the invention is characterized in that the axis of the receptacle, which receives the parts to be pressed, is at an angle deviating from 90 ° to the transverse center plane of the pressing jaws. In conventional pressing devices, the axis of the recording is perpendicular to the transverse center plane, whereby it is often not or only with difficulty possible to reach the parts to be pressed. As a result of obliquely receiving the pressing device according to the invention, it is now possible to use the pressing device in difficult to reach areas to perform there pressings. Such cramped areas are, for example, room corners in which the connecting pieces to be pressed are arranged closely adjacent to a room wall. Due to the skew of the recording, the pressing device can be set in such cases so that the pressing jaws are inclined to the wall, so that they can be easily operated with a drive device.
Vorteilhaft liegt der Winkel, unter dem die Achse der Aufnahme schräg zur Quermittelebene der Pressbacken liegt, in einem Bereich zwischen etwa 30° und etwa 60°.Advantageously, the angle at which the axis of the receptacle is inclined to the transverse center plane of the pressing jaws, in a range between about 30 ° and about 60 °.
Ein bevorzugter Winkel liegt bei etwa 45°. Eine solche Pressvorrichtung kann für die meisten Anwendungsfälle eingesetzt werden.A preferred angle is about 45 °. Such a pressing device can be used for most applications.
Die Pressbacken haben in Endabschnitten Vertiefungen, die in der Schließstellung der Pressbacken die Aufnahme bilden.The pressing jaws have recesses in the end sections, which form the receptacle in the closed position of the pressing jaws.
Die Endabschnitte liegen geneigt zum restlichen Teil der Pressbacken. In diesem Falle ist es zweckmäßig, wenn die Achse der Vertiefungen senkrecht zur Quermittelebene dieser schrägliegenden Endabschnitte verläuft. Die schrägliegenden Endabschnitte ermöglichen den problemlosen Ansatz der Pressvorrichtung an die zu verpressenden Teile, wenn diese ungünstig beispielsweise in Raumecken liegen.The end portions are inclined to the remaining part of the pressing jaws. In this case, it is expedient if the axis of the depressions runs perpendicular to the transverse center plane of these oblique end portions. The oblique end portions allow the problem-free approach of the pressing device to the parts to be pressed, if they are unfavorable example in room corners.
Bei einer vorteilhaften Ausführungsform ragen die Endabschnitte über die eine Breitseite der Pressbacken. Dies erleichtert die Handhabung der Pressvorrichtung bei kritischen Einbauverhältnissen.In an advantageous embodiment, the end portions project beyond the one broad side of the pressing jaws. This facilitates the handling of the pressing device in critical installation conditions.
Die Vertiefungen weisen in vorteilhafter Weise parallel zueinander liegende Ränder auf, die jeweils in einer senkrecht zur Achse der Aufnahme verlaufenden Ebene liegen. Die die Vertiefung aufweisenden Teile der Pressbacken sind dadurch ausreichend stark, dass sie die bei der plastischen Verformung der Verbindungsstücke auftretenden Kräfte aufnehmen können.The recesses advantageously have mutually parallel edges, each extending in a direction perpendicular to the axis of the receptacle Lie flat. The depression having parts of the pressing jaws are characterized strong enough that they can absorb the forces occurring during the plastic deformation of the connecting pieces.
Der eine Rand der Vertiefungen ist vorteilhaft über einen Teil seiner Länge verstärkt ausgebildet. Dies trägt zur hohen Belastbarkeit des entsprechenden Pressbackenbereiches beim Pressvorgang bei.The one edge of the recesses is advantageously formed reinforced over part of its length. This contributes to the high load capacity of the corresponding pressing jaw area during the pressing process.
Diese Verstärkung wird vorteilhaft dadurch erreicht, dass der Endabschnitt einen über seine Oberseite ragenden Vorsprung aufweist, der den Rand der Vertiefungen verstärkt. Es ist grundsätzlich möglich, den gesamten Rand der Vertiefung verstärkt auszubilden. Es reicht aber auch aus, die Randverstärkung nur dort vorzusehen, wo hohe Belastungen auf den Vertiefungsrand wirken.This reinforcement is advantageously achieved in that the end portion has a projecting over its top projection, which reinforces the edge of the recesses. It is basically possible to reinforce the entire edge of the depression. However, it is also sufficient to provide the edge reinforcement only where high loads act on the recess edge.
Eine sichere Verpressung der Teile in der Aufnahme wird in vorteilhafter Weise dadurch sichergestellt, dass die Stirnseiten der Vorsprünge in der Schließstellung der Pressbacken aneinander liegen. Diese Stirnseiten sind in vorteilhafter Weise eben ausgebildet. Bevorzugt liegen die Stirnseiten der Vorsprünge in den einander zugewandten Stirnseiten der Pressbacken.A secure compression of the parts in the receptacle is advantageously ensured by the fact that the end faces of the projections are in the closed position of the pressing jaws together. These end faces are formed flat in an advantageous manner. The end faces of the projections preferably lie in the mutually facing end faces of the pressing jaws.
Bei einer vorteilhaften Ausführungsform sind die Endabschnitte einstückig mit den Pressbacken ausgebildet. Die Presszange lässt sich dadurch kostengünstig fertigen.In an advantageous embodiment, the end portions are formed integrally with the pressing jaws. The pressing tongs can be manufactured inexpensively.
Bei einer vorteilhaften Ausführungsform ist die Aufnahme, die durch die beiden Vertiefungen gebildet wird, an einem Pressring vorgesehen, der an die Pressbacken angeschlossen wird, die Teil einer Zwischenzange sind. Diese Ausbildung der Pressvorrichtung hat den Vorteil, dass die Zwischenzange und der Pressring mit der Aufnahme aus dem jeweils günstigsten Material gefertigt werden können. Der Pressring kann beispielsweise mittels Schrauben, Pressbolzen, einrastenden Federdruckstücken und dergleichen mit den Pressbacken verbunden werden. Diese Ausbildung hat den Vorteil, dass der Pressring bei Bedarf ausgewechselt werden kann, wenn er beispielsweise beschädigt ist. An die Pressbacken können auch Pressringe angeschlossen werden, die für unterschiedliche Werkstückdurchmesser und/oder für unterschiedliche Presskonturen eingesetzt werden sollen.In an advantageous embodiment, the receptacle, which is formed by the two recesses, provided on a pressing ring, which is connected to the pressing jaws, which are part of an intermediate pair of pliers. This design of the pressing device has the advantage that the intermediate pliers and the press ring can be made with the inclusion of the most favorable material. The pressing ring can be connected to the pressing jaws, for example, by means of screws, pressing bolts, latching spring pressure pieces and the like. This training has the advantage that the Press ring can be replaced if necessary, for example, if it is damaged. Press rings can also be connected to the pressing jaws, which are to be used for different workpiece diameters and / or for different pressing contours.
Der Pressring besteht bei einer vorteilhaften Ausführungsform aus zwei gelenkig miteinander verbundenen Backen, die an die Enden der Pressbacken der Pressvorrichtung angeschlossen sind.The pressing ring consists in an advantageous embodiment of two hingedly interconnected jaws, which are connected to the ends of the pressing jaws of the pressing device.
Die Backen des Pressringes sind vorteilhaft an ihrem von den Pressbacken abgewandten Enden gelenkig miteinander verbunden. Die Backen des Pressringes bilden somit einarmige Hebel. Aufgrund dieser Ausbildung lässt sich der Pressring sehr einfach betätigen.The jaws of the pressing ring are advantageously connected to one another at their ends facing away from the pressing jaws in an articulated manner. The jaws of the press ring thus form one-armed levers. Due to this training, the pressing ring can be operated very easily.
Die beiden Backen des Pressringes sind jeweils mit einer Vertiefung versehen, die in Schließstellung der Backen die Aufnahme bilden. Die Backen des Pressringes können somit zum Einlegen des zu verpressenden Werkstückes mittels der Pressbacken der Pressvorrichtung auseinandergeschwenkt werden. Anschließend werden die Pressbacken der Pressvorrichtung beispielsweise mittels eines motorischen Antriebes so gegeneinander verschwenkt, dass die Backen des Pressringes geschlossen werden. Das in den Vertiefungen liegende Werkstück wird dadurch radial verpresst.The two jaws of the press ring are each provided with a recess which form the receptacle in the closed position of the jaws. The jaws of the press ring can thus be pivoted apart for insertion of the workpiece to be pressed by means of the pressing jaws of the pressing device. Subsequently, the pressing jaws of the pressing device are pivoted, for example by means of a motor drive against each other so that the jaws of the pressing ring are closed. The lying in the wells workpiece is thereby pressed radially.
Damit der Pressring einwandfrei schräg gegenüber den Pressbacken der Pressvorrichtung positioniert werden kann, sind bei einer vorteilhaften Ausführungsform die Pressbacken am freien Ende mit Anschlagflächen versehen. An ihnen liegen die Backen des Pressringes mit entsprechenden Gegenanschlagflächen an. Dadurch lässt sich der Pressring einwandfrei in Bezug auf die Pressbacken der Pressvorrichtung positionieren.So that the pressing ring can be positioned correctly obliquely opposite the pressing jaws of the pressing device, in an advantageous embodiment the pressing jaws are provided with stop surfaces at the free end. At them are the jaws of the press ring with corresponding counter stop surfaces. As a result, the pressing ring can be perfectly positioned with respect to the pressing jaws of the pressing device.
Die Quermittelebene des Pressringes liegt in bevorzugter Weise unter einem von 90° abweichenden Winkel zur Quermittelebene der Pressbacken.The transverse center plane of the pressing ring is preferably at an angle deviating from 90 ° to the transverse center plane of the pressing jaws.
