Abstract
Description
Die Erfindung betrifft die Verwendung von an den freien Enden von Pressbacken einer Presszange jeweils vorgesehenen zweiten Anschlüssen nach dem Oberbegriff des Anspruches 1.The invention relates to the use of respectively provided at the free ends of pressing jaws of a pressing tongs second terminals according to the preamble of
Eine derartige Presszange ist bekannt aus einer Montageleitung der Firma Velta 7/93.Such a pressing tongs is known from an assembly line of the company Velta 7/93.
Presszangen werden hauptsächlich in der Sanitärinstallation eingesetzt, um zwei Rohre oder Rohrstücke über Verbindungsstücke, sogenannte Fittings, miteinander zu verbinden. Hierzu werden die Verbindungsstücke über die Enden zweier Rohre geschoben und plastisch verformt, um eine feste Verbindung zwischen den beiden Rohren über das Verbindungsstück zu erreichen. Die Presszangen haben hierfür zwei Pressbacken mit jeweils eingearbeiteter systemspezifischer Presskontur. Um die Pressbacken zu betätigen und insbesondere die Presskraft aufzubringen, wird die Presszange mit dem ersten Anschluss an eine motorische Antriebsvorrichtung mit einem axial verstellbaren Stößel angeschlossen. Solche Antriebsvorrichtungen arbeiten elektromechanisch oder elektrohydraulisch. Der Stößel trägt Druckrollen, mit denen beim Ausfahren des Stößels die Presszange geschlossen und damit die Presskraft aufgebracht wird.Crimping pliers are mainly used in sanitary installations to connect two pipes or pieces of pipe via fittings known as fittings. For this purpose, the connecting pieces are pushed over the ends of two tubes and plastically deformed in order to achieve a firm connection between the two tubes via the connecting piece. The pressing tongs have two press jaws for this purpose, each with an integrated system-specific press contour. In order to actuate the pressing jaws and in particular to apply the pressing force, the pressing tongs with the first connection are connected to a motor drive device with an axially adjustable tappet. Such drive devices operate electromechanically or electro-hydraulically. The plunger carries pressure rollers with which the pressing pliers are closed during extension of the plunger and thus the pressing force is applied.
Es sind auch handbetätigte Pressvorrichtungen in Form von Rohrzangen bekannt, bei denen die jeweilige Presskontur einstückig eingearbeitet ist. Darum ist für jede Rohrgröße eine gesonderte Rohrzange erforderlich. Es sind auch Wechseleinsätze bekannt, welche die Presskontur enthalten und in die Rohrzange eingesetzt werden. Dann kann die Rohrzange für einen begrenzten Durchmesserbereich der zu verpressenden Rohre bzw. Verbindungsstücke eingesetzt werden.There are also hand-operated pressing devices in the form of pipe wrenches are known in which the respective pressing contour is integrally incorporated. Therefore, a separate pipe wrench is required for each pipe size. There are also known inserts, which contain the pressing contour and are used in the pipe wrench. Then the pipe wrench can be used for a limited diameter range of the pipes or connectors to be pressed.
Es sind auch Antriebsvorrichtungen bekannt, die aus zwei gelenkig miteinander verbundenen Hebeln bestehen, mit denen die Pressbacken direkt geöffnet bzw. geschlossen werden können. Diese Presszangen sind im Vergleich zu den Presszangen für die motorischen Antriebsvorrichtungen unterschiedlich gestaltet. Der Benutzer der Presszangen benötigt darum für den Einsatz der manuellen und der motorischen Antriebsvorrichtungen jeweils eigene Sätze von Presszangen.There are also known drive devices which consist of two hingedly interconnected levers with which the pressing jaws can be directly opened or closed. These pressing tongs are designed differently in comparison to the pressing tongs for the motor drive devices. The user of the pressing tongs therefore requires separate sets of pressing tongs for the use of the manual and the motor drive devices.

Der Erfindung liegt die Aufgabe zugrunde, die Presszange so zu Verwenden, dass sie kostengünstig für unterschiedliche Pressaufgaben herangezogen werden kann.The invention has for its object to use the crimping pliers so that they can be used inexpensively for different pressing tasks.
Diese Aufgabe wird erfindungsgemäß mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with the features of
Infolge der erfindungsgemäßen Ausbildung kann die Presszange über ihre beiden Anschlüsse wahlweise manuell oder motorisch angetrieben werden. Beide Anschlüsse sind als lösbare Anschlüsse ausgebildet, so dass der Benutzer an die beiden Anschlüsse wahlweise eine motorische und eine manuelle Antriebsvorrichtung anschließen kann. Die Presszange lässt sich mit dem ersten Anschluss an die motorische Antriebsvorrichtung anschließen. Möchte der Benutzer hingegen die Presszange manuell betätigen können, wird sie über den zweiten Anschluss an die manuelle Antriebsvorrichtung angeschlossen. Der Benutzer ist darum nicht mehr genötigt, für die unterschiedlichen Arbeiten von Antriebsvorrichtungen unterschiedliche Presszangen mit systemspezifischer Presskontur oder Presswerkzeuge mit Wechseleinsätzen oder unterschiedliche Rohrzangen anzuschaffen. Die erfindungsgemäße Verwendung ermöglicht dem Benutzer, je nach gewünschter Einsatzart die Presszange an die manuelle oder an die motorische Antriebsvorrichtung anzuschließen.As a result of the construction according to the invention, the pressing tongs can be driven either manually or by motor via its two connections. Both terminals are formed as detachable terminals, so that the user can connect to the two ports optionally a motorized and a manual drive device. The pressing tongs can be connected with the first connection to the motor drive device. If, on the other hand, the user wishes to be able to manually operate the pressing tongs, they are connected to the manual drive device via the second connection. The user is therefore no longer forced to purchase different crimping pliers with system-specific pressing contour or pressing tools with interchangeable inserts or different pipe wrenches for the different works of drive devices. The use according to the invention allows the user to connect the crimping tool to the manual or to the motorized drive device, depending on the desired type of use.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention will become apparent from the other claims, the description and the drawings.
