Abstract
Description
Die Erfindung bezieht sich auf ein Aufspannwerkzeug für einen einschweißbaren Abzweigsattel für Kunststoffrohre.The invention relates to a Clamping tool for a weldable Branch saddle for Plastic pipes.
Im Stand der Technik sind Elektroschweißverbindungen für das Verschweißen von Rohren oder Sätteln bekannt, bei denen die Heizwicklung in einer Ebene angeordnet ist. Als Heizwicklung wird üblicherweise ein Kupferdraht eingesetzt. Wird eine solche Anordnung für das Einschweißen von Abzweigsätteln oder Abgängen für Kunststoffrohre eingesetzt, besteht der Nachteil, daß der Sattel und das Kunststoffrohr gut zueinander passen müssen, was bei aus Polyäthylen bestehenden Rohren nicht immer der Fall ist. Die Schweißung soll die Abdichtung und den mechanischen Halt des Abzweigsattels am Kunststoffrohr garantieren.In the prior art are electro-welded joints for the weld together of pipes or saddles known, in which the heating coil is arranged in a plane. As a heating coil is usually a copper wire used. If such an arrangement for the welding of branch saddles or disposals for plastic pipes used, there is the disadvantage that the saddle and the plastic tube have to fit well with each other, what about polyethylene existing pipes is not always the case. The weld should the sealing and the mechanical hold of the branch saddle on the plastic pipe to guarantee.
Aus der
Der Erfindung liegt demgegenüber die Aufgabe zugrunde, ein Aufspannwerkzeug für einen einschweißbaren Abzweigsattel für Kunststoffrohre zu schalten, mit dem eine ausreichende Vorspannung erreichbar ist, wobei die Sattelfläche des Abzweigsattels an der Innenseite des Kunststoffrohres anliegt, und mit dem. während des Schweißvorganges ein nahezu gleichmäßiger Druck aufrechterhalten werden kann.The invention is in contrast to the Task based, a clamping tool for a weldable Abzweigsattel for plastic pipes to switch, with which a sufficient bias voltage can be achieved, the saddle surface of the branch saddle rests against the inside of the plastic tube, and with that. while of the welding process almost uniform pressure can be maintained.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This underlying the invention Task is solved by the teaching of the main claim.
Mit anderen Worten ausgedrückt wird ein Werkzeug vorgeschlagen, das in das Innere des Rohres eingeführt werden kann und von außen betätigt werden kann und das dafür Sorge trägt, daß die Sattelfläche des Abzweigsattels mit einer einstellbaren Vorspannung an der Unterseite des Kunststoffrohres anliegt, bevor der eigentliche Schweißvorgang eingeleitet wird. Dabei ist dieses Aufspannwerkzeug so ausgebildet, daß einerseits die Druckwirkung auf die Sattelfläche von der Außenseite des Rohres her erzeugt wird und gleichzeitig der Anschluß des Schweißgerätes vom Äußeren des Rohres her durchgeführt werden kann.Expressed in other words proposed a tool that are inserted into the interior of the pipe can and from the outside actuated can be and for that Caring, that the saddle surface of the Branch saddle with an adjustable preload on the bottom the plastic tube rests before the actual welding process is initiated. In this case, this clamping tool is designed to that on the one hand the pressure effect on the saddle surface from the outside the tube is produced ago and at the same time the connection of the welding device from the outside of the Tube carried out ago can be.
Gemäß der Erfindung wird daher die Verwendung eines einschweißbaren Abzweigsattels vorgeschlagen, der sich durch einen Rohrstutzen kennzeichnet und eine damit fest verbundene Sattelfläche, deren Formgebung dem Innenradius des Kunststoffrohres angepaßt ist und an deren Oberseite eine Heizwendel mit aufrechtstehender Heizwicklung fest eingeschmolzen ist, wobei die Einschmelztiefe etwa der Drahtstärke der Heizwendel entspricht und Kontakte zur Schweißenergiezufuhr einander gegenüberliegend in Längsachse des Kunststoffrohres ausgerichtet vorgesehen sind.Therefore, according to the invention the use of a weldable Proposed branch caliper, which is characterized by a pipe socket and a fixed saddle surface, the shape of the inner radius adapted to the plastic tube is and at the top of a Heizwendel with upright Heating coil is firmly sealed, the melting depth about the wire thickness the heating coil corresponds and contacts for welding energy supply opposite each other in longitudinal axis are provided aligned with the plastic tube.
Zum Einfügen dieses Abzweigsattels wird gemäß der Erfindung ein Werkzeug vorgesehen, das eine federnde Druckplatte, eine mit der Druckplatte unter Zwischenschaltung von Federelementen in Verbindung stehende Zugplatte und eine an der Zugplatte angreifende Zugstange aufweist, wobei sich die Zugstange in einem auf der Außenseite des Kunststoffrohres abstützenden Zugaufnehmer führt und nach Einführen des Aufspannwerkzeuges an das Werkzeug ansetzbar ist.To insert this branch saddle is according to the invention a tool provided with a resilient pressure plate, one with the pressure plate with the interposition of spring elements in conjunction standing tension plate and an attacking on the tension plate tie rod having the pull rod in one on the outside supporting the plastic pipe Zugaufnehmer leads and after insertion the Aufspannwerkzeuges can be attached to the tool.
Vorzugsweise ist die Zugplatte über Führungsstangen starr mit einem Schlitten verbunden, der als Träger für das Aufspannwerkzeug in das Rohr eingezogen werden kann und hierzu beispielsweise Zugösen für ein Zugseil und Zugösen für ein Rückholseil aufweist, wobei aber auch anstelle dieser Ösen oder zusätzlich entsprechende Rohrstutzen zur Aufnahme eines Schubstabes vorgesehen sein können.Preferably, the tension plate is connected via guide rods rigidly connected to a carriage, which can be drawn as a support for the Aufspannwerkzeug in the tube and this example draw eyes for a pull rope and drawbar eyes for a return rope, but also instead of these eyelets or in addition corresponding pipe socket for receiving a push rod may be provided NEN.
Die federnde Druckplatte ist zusätzlich mit einem aus elastischem, aber wärmebeständigen Werkstoff bestehenden Druckring ausgerüstet, wobei die Druckplatte über Traversen beaufschlagt wie eine Blattfeder wirkt. Unterhalb der Druckplatte ist ein Klemmträger vorgesehen, der Anschlußklemmen für Kontakte zur Schweißenergiezufuhr trägt.The resilient pressure plate is also with one made of elastic but heat-resistant material equipped with existing pressure ring, the pressure plate over Travers acts like a leaf spring acts. Below the Pressure plate is a clamp carrier provided, the terminals for contacts for welding energy supply wearing.
Vorzugsweise sind die Federelemente als Wendelfedern ausgebildet.Preferably, the spring elements designed as coil springs.
Der eigentliche Zugaufnehmer stützt sich über Auflagerholme auf der Außenseite des mit dem Abzweigsattel zu versehenden Kunststoffrohres ab und bildet also ein Widerlager. Die Zugstange weist eine mit einem Außengewinde kämmende Spannmutter auf.The actual Zugaufnehmer relies on Auflagerholme on the outside of the branch pipe to be provided with the plastic pipe from and thus forms an abutment. The drawbar has one with an external thread meshing Clamping nut on.
