Description

Die Erfindung betrifft einen Elektrodentragarm der im Oberbegriff des Patentanspruchs 1 umrissenen Gattung. Ein solcher Elektrodentragarm ist beispielsweise beschrieben in der DE-OS 34 43 574.The invention relates to an electrode support arm of the type outlined in the preamble of claim 1. Such an electrode arm is described for example in DE-OS 34 43 574.

Nach dem Stand der Technik wird für die Einspannung der Elektrode und die damit einhergehende Anpressung der Elektrode gegen die Kontaktbacke ein vom Elektrodentragarm ausgehender Spannbügel vorgesehen, der mit in den Elektrodentragarm eingelagerten Spannmitteln gegen die Elektrode angezogen wird. Der Mechanismus zum Spannen des Spannbügels und insbesondere dann auch das dafür erforderliche Aggregat, in der Regel ein Hydraulikzylinder, sind im Elektrodentragarm untergebracht. Der Elektrodentragarm muß dementsprechend voluminös dimensioniert werden.According to the state of the art, a clamping bracket starting from the electrode support arm is provided for the clamping of the electrode and the associated pressing of the electrode against the contact jaw, which is tightened against the electrode with clamping means embedded in the electrode support arm. The mechanism for tensioning the clamping bracket and in particular then the unit required for this, usually a hydraulic cylinder, are accommodated in the electrode support arm. The electrode support arm must be dimensioned accordingly bulky.

Ausgehend vom im vorausgehenden umrissenen Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine günstigere Elektrodeneinspannung vorzuschlagen.Starting from the prior art outlined above, the object of the invention is to propose a more favorable electrode clamping.

Die Aufgabe wird erfindungsgemäß mit einem gattungsgemäßen Elektrodentragarm gelöst, der entsprechend dem kennzeichnenden Teil des Patentanspruchs 1 ausgebildet ist.The object is achieved with a generic electrode support arm, which is designed according to the characterizing part of claim 1.

Nach der Erfindung ist dem Elektrodentragarm als Elektrodenaufnahme an seinem freien Ende ein verwindungssteifer Bügel lagefixiert zugeordnet, in dem auf der von der Kontaktbacke abgekehrten Seite symmetrisch zur Tragarmlängsachse hydraulisch betätigbare Zylinder eingelagert sind, deren auf das Zentrum der Aufnahme orientierte Kolbenstangen in ein gegen die einzuspannende Elektrode zur Anlage kommendes Klemmstück auslaufen. Wenn auch aus Sicherheitsgründen solchen Zylindern der Vorzug zu geben ist, die unter Federdruck anstellen und durch ringraumseitige Druckmittelbeaufschlagung außer Eingriff gebracht werden, schließt das beidseitige druckmittelbeaufschlagbare Zylinder nicht aus. Nach einer bevorzugten Ausführungsform sind symmetrisch zur Tragarmlängsachse jeweils zwei im Abstand voneinander untereinander angeordnete Zylinder vorgesehen, die zum einen die lotrechte Einspannung der Elektrode stabilisieren, und zum anderen in Verbindung mit einstellbeweglichen Kontaktbacken die Möglichkeit eröffnen, ungedrehte Elektroden einzusetzen.According to the invention, the electrode support arm is assigned a torsionally stiff bracket fixed in position as an electrode receptacle, in which hydraulically actuatable cylinders are embedded on the side facing away from the contact jaw symmetrically to the longitudinal axis of the support arm, the piston rods of which are oriented towards the center of the receptacle into an electrode to be clamped against the electrode leak the coming clamping piece. Even if, for safety reasons, preference is given to such cylinders that engage under spring pressure and are disengaged by pressurizing the pressure on the annulus side, the pressurizable cylinder on both sides does not rule out. According to a preferred embodiment, two cylinders spaced from one another are provided symmetrically to the longitudinal axis of the support arm, which on the one hand stabilize the vertical clamping of the electrode and on the other hand, in conjunction with adjustable contact jaws, open up the possibility of using non-rotated electrodes.

Die erfindungsgemäße Elektrodeneinspannung gestattet es, Elektrodentragarme mit geringeren Querschnitten vorzusehen. Gegebenenfalls steht der Freiraum im hohlen Elektrodentragarm dann auch für andere Zwecke zur Verfügung. Der Anstellmechanismus ist weniger aufwendig. Die nach der Erfindung vorgesehenen Zylinder zum Einspannen der Elektrode sind im übrigen leicht zugänglich und lassen sich somit im Bedarfsfall leicht auswechseln.The electrode clamping according to the invention makes it possible to provide electrode support arms with smaller cross sections. The space in the hollow electrode support arm may then also be available for other purposes. The adjustment mechanism is less complex. The cylinders provided according to the invention for clamping the electrode are otherwise easily accessible and can therefore be easily replaced if necessary.

Am freien Ende des Elektrodentragarms 11 sitzt die Kontaktbacke 12 auf, in der auf einem dem Radius der Elektrode 31 entsprechenden Radius symmetrisch zur Tragarmlängsachse 111 Kontaktstücke 121, 122 einstellbeweglich gelagert sind. Integrierter Bestandteil des Tragarms 11 ist des weiteren der stirnseitig an ihr angesetzte verwindungssteife Bügel 21, in den auch wieder symmetrisch zur Tragarmlängsachse 111 Zylinder 22, 23 eingelagert sind, deren Kolbenstangen 221 auf das Zentrum des Bügels 21 orientiert sind und in gegen die Elektrode 31 zur Anlage kommende Klemmstücke 223 mit der Elektrode 31 angepaßte Anlagefläche auslaufen. Die Zylinderkolben 221 sind von einem Federpaket 224 hinterfangen, die das Ausfahren des Kolbens 221 bewirken und damit die Anstellung der Klemmstücke 223 über die Kolbenstange 222 gegen die Elektrode 31. Zum Elektrodenwechsel wird der Ringraum 226 des Zylinders über die Druckmittelleitung 227 mit Druckmittel beaufschlagt, so daß der Kolben gegen die Wirkung der Anstellfeder 224 einfährt und das Klemmstück 223 von der Elektrode 31 abhebt. Die Druckmittelleitung 227 ist am Elektrodentragarm 11 entlang und weiter zum Steuerstand geführt, von dort erfolgt im Bedarfsfall die Betätigung der Zylinder 22, 23.At the free end of the electrode support arm 11, the contact jaw 12 is seated, in which contact pieces 121, 122 are mounted for adjustment on a radius corresponding to the radius of the electrode 31 symmetrically to the longitudinal axis 111 of the support arm. An integral part of the support arm 11 is furthermore the torsionally stiff bracket 21 attached to its end face, in which cylinders 22, 23 are also symmetrically embedded with the support arm longitudinal axis 111, the piston rods 221 of which are oriented towards the center of the bracket 21 and against the electrode 31 Coming coming clamping pieces 223 with the electrode 31 adapted contact surface. The cylinder pistons 221 are covered by a spring assembly 224, which cause the piston 221 to extend and thus cause the clamping pieces 223 to move against the electrode 31 via the piston rod 222. To change the electrodes, the annular space 226 of the cylinder is pressurized via the pressure medium line 227, so that the piston retracts against the action of the adjusting spring 224 and the clamping piece 223 lifts off the electrode 31. The pressure medium line 227 is guided along the electrode support arm 11 and further to the control station, from where the cylinders 22, 23 are actuated if necessary.

Wie aus Figur 2 zu entnehmen ist, sind jeweils zwei Zylinder, z.B. 23, 23', im Abstand voneinander untereinander vorgesehen. Damit wird die lotrechte Orientierung der eingespannten Elektrode 31 sichergestellt. In Verbindung mit einstellbeweglichen Kontaktstücken, z.B. 122, ergibt sich des weiteren die Möglichkeit des Einsatzes von ungedrehten Elektroden.As can be seen from Figure 2, two cylinders, e.g. 23, 23 ', at a distance from one another. This ensures the perpendicular orientation of the clamped electrode 31. In connection with adjustable contact pieces, e.g. 122, there is also the possibility of using non-rotated electrodes.
