Einspannvorrichtung für elektrische Stumpfschweißmaschinen.Clamping device for electric butt welding machines.
Die Erfindung bezieht sich auf Einspannvorrichtungen für elektrische Stumpfschweißmaschinen und besteht in einer derartigen Ausbildung derselben, daß sie für das Schweißen von geraden oder gebogenen Werkstücken bzw. von Bändern oder Ringen von verschiedenem Durchmesser, Breite und Stärke geeignet sind. Hierdurch werden besondere Einspannvorrichtungen oder -backen für diese verschiedenen Werkstücke überflüssig, und es wird die Zeit für das Auswechseln der Spezialbacken erspart.The invention relates to clamping devices for electric butt welding machines and consists in such a design the same that they are suitable for welding straight or curved Workpieces or strips or rings of different diameters, widths and Strength are suitable. This creates special clamping devices or jaws superfluous for these different workpieces and it is time to replace them which saves special jaws.
Gemäß der Erfindung werden die stromführenden. Einspannbacken um zueinander parallele Achsen schwenkbar und in beliebiger Schräglage feststellbar gemacht und erhalten zweckmäßig Klemmvorrichtungen, die bei Bewegung der Einspannbacken behufs Stauchung des Werkstückes sich selbsttätig schließen.According to the invention, the current-carrying. Clamping jaws to each other parallel axes pivotable and made lockable in any inclined position and expediently receive clamping devices that act upon movement of the clamping jaws Compression of the workpiece close automatically.
Ein Ausführungsbeispiel der neuen Einspannvorrichtung ist in der Zeichnung dargestellt. An embodiment of the new clamping device is shown in the drawing.
Abb. ι zeigt die ausgeschwenkten Einspannbacken zur Verwendung für gerade Werkstücke, Fig. Ι shows the swiveled-out clamping jaws for use for straight workpieces,
Abb. 2 einwärts geschwenkte Einspannbacken zum Schweißen von Ringen undFig. 2 clamping jaws pivoted inwards for welding rings and
Abb. 3 einen Schnitt nach der Linie A-B der Abb. 1.Fig. 3 shows a section along the line AB in Fig. 1.
Die Schweißbacken: a, b sind um die zueinander parallelen Achsen c, d schwenkbar gelagert, wobei die Schwenkbewegung durch Stellschrauben e begrenzt werden kann. In jeder Einspannbacke sind Schlitten g gleitend geführt, die durch Bewegungsspindeln h und Kurbeln I den Schweißbacken a, b genähert oder von ihnen entfernt werden können. Die Schlitten g tragen Klemmhebel /, die sich in solcher Lage zu den Backen a, b befinden, daß sie bei der gegenseitigen Annäherung der Backen die Werkstücke nach Art eines Klemmgesperres fassen. Die Einstellung entsprechend der Stärke des Werkstücks erfolgt durch die Spindeln //; es sind aber auch Exzenter/e vorgesehen, die ein rasches Verschieben und Feststellen des Schlittens g und somit ein Schnelleinspannen gestatten.The welding jaws : a, b are mounted pivotably about the mutually parallel axes c, d , whereby the pivoting movement can be limited by adjusting screws e. In each clamping jaw slides are slidably guided g, h by moving spindles and cranks I the welding jaws a, b approached or may be removed from them. The carriages g carry clamping levers / which are in such a position to the jaws a, b that they grasp the workpieces in the manner of a locking mechanism when the jaws approach one another. The setting according to the thickness of the workpiece is made by the spindles //; However, eccentrics are also provided which allow the slide g to be moved and locked in place quickly and thus to be clamped quickly.
Wie Abb. 3 zeigt, sind Auflager m verschiebbar an den Schweißbacken angeordnet, die gestatten, Werkstücke von verschiedener Breite in die Mittellage zur Schweißbacke zu bringen, so daß stets eine gleichmäßige Stromverteilung und eine gleichmäßige Erwärmung der Schweißstücke gesichert ist. Werden die Schweißbacken in der Richtung der Pfeile gegeneinander bewegt, so tritt nach dem Aufeinandertreffen der Stirnflächen der Schweißstücke (beim Stauchen) zwischen den Klemmhebcln / und den Schweißbacken a, b eine ähnliche Wirkung auf wie bei Klemmgesperren; es werden entsprechend demAs Fig. 3 shows, supports m are slidably arranged on the welding jaws, which allow workpieces of different widths to be brought into the central position of the welding jaw, so that an even current distribution and uniform heating of the welding pieces is always ensured. If the welding jaws are moved towards one another in the direction of the arrows, then after the end faces of the welding pieces meet (when upsetting) between the clamping levers / and the welding jaws a, b, an effect similar to that of clamping locks occurs; it will be according to the

steigenden Stauchdruck die Schweißstücke auch stärker gehalten.Increasing upsetting pressure also holds the weldments stronger.
