Description

Abdeckung der flexiblen Stromzuführungen zu den Elektroden einer Abbrenn-Stumpfschweißmaschine Die Erfindung bezieht sich auf eine Abdeckung der flexiblen Stromzuführungen zu den Elektroden einer Abbrenn-Stumpfschweißmaschine, bei der die Abdeckungen für den beweglichen und den festen Spannbock voneinander getrennt sind. Bei den bekannten Abdeckungen sind sowohl an dem festen Spannbock als auch an dem beweglichen Spannbock Abdeckbleche starr befestigt, die gemeinsam die Stromzuführungen abdecken. Die beiden Abdeckbleche müssen gegeneinander isoliert werden. Außerdem ist eine große Anzahl von Befestigungsschrauben erforderlich. Man hat auch schon die beiden Abdeckbleche beweglich an den Spannböcken befestigt und durch Scharniere miteinander verbunden. Auch hier müssen die Abdeckbleche gegeneinander isoliert werden. Außerdem liegen die Scharniere im Spritzbereich der Schweißstelle und werden durch die sich sammelnden Spritzer schon nach kurzer Betriebszeit bewegungsunfähig.Covering the flexible power supply lines to the electrodes of a flash butt welding machine The invention relates to a cover for the flexible power supply lines the electrodes of a flash butt welding machine in which the covers are used for the movable and fixed clamping brackets are separated from each other. With the known Covers are on both the fixed clamp and the movable clamp Cover plates rigidly attached, which together cover the power supply lines. The two Cover plates must be insulated from each other. Also is a large number of fastening screws required. You already have the two cover plates movably attached to the brackets and connected to one another by hinges. Here, too, the cover plates must be insulated from one another. Also lie the hinges in the splash area of the weld and are collected by the Splashes immobilized after a short period of operation.

Die Erfindung vermeidet diese Nachteile. Erfindungsgemäß besteht die Abdeckung für den beweglichen Spannbock aus einem am Transformator scharnierartig befestigten Abeckblech, das mit seinem elektrodenseitigen Ende verschiebbar geführt ist. Eine zweckmäßige Ausführung ergibt sich, wenn das elektrodenseitige Ende des Abdeckbleches mit einer verstärkten abgerundeten Kante in eine an dem beweglichen Spannbock befestigte gabelartige Führung hineinragt.The invention avoids these disadvantages. According to the invention, the Cover for the movable clamping block from a hinge-like on the transformer attached cover plate, which is guided displaceably with its electrode-side end is. An expedient embodiment results when the electrode-side end of the Cover plate with a reinforced rounded edge in one on the movable Clamping bracket attached fork-like guide protrudes.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Sie zeigt die Stromzuführung zu den Elektroden einer Abbrenn-Stumpfschweißmaschine in Ansicht von oben.An embodiment of the invention is shown in the drawing. It shows the power supply to the electrodes of a flash butt welding machine in top view.

Der Transformator 1 ist durch die Stromzuführungen 2 mit der Elektrode 3 des festen Spannbockes 4 und durch die Stromzuführungen 5 mit der Elektrode 6 des beweglichen Spannbockes 7 verbunden. Die Stromzuführungen 2 zu der festen Elektrode 3 sind durch ein Abdeckblech 8 geschützt, das an dem Spannbock 4 mittels weniger leicht zugänglicher Schrauben 9 und 10 starr befestigt ist. Die Abdeckung für die Stromzuführungen 5 zu der beweglichen Elektrode 6 besteht aus einem Abdeckblech 11, das an dem Transformator 1 durch ein Scharnier 12 drehbar befestigt ist. Mit seinem elektrodenseitigen Ende, das mittels eines angeschweißten Stabes 13 abgerundet und verstärkt ist, ragt es in eine gabelartige Führung 14 hinein, die an dem festen Spannbock 7 befestigt ist. Durch diese gabelartige Führung kann das Abdeckblech 11 die Bewegungen des beweglichen Spannbockes mitmachen, wobei stets die Stromzuführungen 5 vollständig gegen die Schweißstelle abgedeckt sind.The transformer 1 is connected by the power supply lines 2 to the electrode 3 of the fixed clamping block 4 and by the power supply lines 5 to the electrode 6 of the movable clamping block 7. The power supply lines 2 to the fixed electrode 3 are protected by a cover plate 8 which is rigidly attached to the clamping block 4 by means of screws 9 and 10 that are less easily accessible. The cover for the power supply lines 5 to the movable electrode 6 consists of a cover plate 11 which is rotatably fastened to the transformer 1 by a hinge 12. With its electrode-side end, which is rounded and reinforced by means of a welded-on rod 13, it protrudes into a fork-like guide 14 which is fastened to the fixed clamping block 7. By means of this fork-like guide, the cover plate 11 can join in the movements of the movable clamping block, the power supply lines 5 always being completely covered against the welding point.

Die Erfindung bietet folgende Vorteile: Die Abdeckbleche bilden glatte Wände, die leicht zu reinigen sind. Eine Isolierung des Abdeckbleches für die bewegliche Elektrode gegen das Abdeckblech für den festen Spannbock ist nicht erforderlich. Das Scharnier für das Abdeckblech des beweglichen Spannbockes ist so weit von der Schweißstelle entfernt, daß das Ansammeln von Schweißspritzern nicht zu befürchten ist.The invention offers the following advantages: The cover plates are smooth Walls that are easy to clean. An insulation of the cover plate for the movable Electrode against the cover plate for the fixed clamp is not required. The hinge for the cover plate of the movable clamping block is so far from the Welding point removed so that welding spatter does not have to be feared is.
