Abstract
Description
Die Erfindung betrifft eine Einspannung für die auswechselbare Elektrode eines Elektroschmelzaggregats, bestehend aus einer am freien Ende des Elektrodentragarms befindlichen Kontaktbacke, einem sich am freien Ende des Tragarms führenden, die Elektrode umfassenden Spannbügel und einem im Tragarm gelagerten Spannzylinder, dessen am Spannbügel angreifende Kolbenstange unter der Einwirkung eines im Ringraum des Spannzylinders befindlichen Federpakets, den Spannbügel klemmend gegen die von ihm umfangene Elektrode zur Anlage bringt, mit einem bodenseitigen Anschluss für die Einspeisung von Druckmittel in den bodenseitigen Zylinderraum des Spannzylinders zum Lösen des Spannbügels.The invention relates to a clamping for the replaceable electrode of an electric melting unit, consisting from a contact jaw located at the free end of the electrode support arm, a leading at the free end of the support arm, enclosing the electrode tensioning bow and a tensioning cylinder mounted in the support arm, the one acting on the tensioning bracket Piston rod under the action of one located in the annulus of the clamping cylinder Spring pack, the clamp jamming against the electrode that he encompasses, with a bottom connection for the supply of pressure medium in the bottom cylinder space of the clamping cylinder to release the Tensioning bow.
Der Bestandteil der Einspannung bildende Spannzylinder, insbesondere das die Anstellung des Zylinders bewirkende Federpaket, bedarf der Ermüdung des Federpakets wegen nach längerem Einsatz der Einspannung des Austauschs. Dazu muss der zunächst im Elektrodentragarm befindliche Spannzylinder vor Ort ausgebaut und gegebenenfalls im Anschluss an seine Nachrüstung mit einem neuen Federpaket wieder in den Elektrodentragarm überführt werden. Zum Ausbau des nach dem Stand der Technik überwiegend von der Stirnseite des Elektrodentragarms her in den Elektrodentragarm eingesetzten Spannzylinders bedarf es des Lösens des sich am Elektrodentragarm führenden, mit der Kolbenstange des Spannbügels zusammengefassten Spannbügels, anschließend des Lösens des Spannzylinders vom Elektrodentragarm, der im Betriebszustand durch Schraubverbindungen des Zylinders mit dem Elektrodentragarm zusammengefasst ist. Diese den Spannzylinder mit dem Elektrodentragarm zusammenfassenden Schraubverbindungen befinden sich in aller Regel im stirnseitigen Bereich des Elektrodentragarms. Sie sind dort einer erheblichen Verschmutzung, dann auch extrem hohen Temperaturen ausgesetzt, Einflüsse, die die Lösbarkeit der Schraubverbindungen stark beeinträchtigen.The component of the clamping cylinders forming the clamping, in particular the spring assembly causing the cylinder to move, needs fatigue due to the spring assembly after a long time Use of the clamping of the exchange. To do this, the Electrode support arm located tensioning cylinder removed on site and if necessary after retrofitting with a new spring package be transferred back to the electrode support arm. To expand the state of the art mainly from the front of the electrode support arm forth in the electrode support arm inserted cylinder it needs to be solved of the leading on the electrode support arm, with the piston rod of the clamping bracket summarized clamp, subsequently of loosening of the clamping cylinder from the electrode support arm, which in the operating state Screw connections of the cylinder combined with the electrode support arm is. These combine the clamping cylinder with the electrode support arm Screw connections are usually located on the front Area of the electrode support arm. You are a significant one there Pollution, then also exposed to extremely high temperatures, influences that the solvability the screw connections severely impair.
Vor diesem Hintergrund liegt der Erfindung in erster Linie die Aufgabe zugrunde, eine Lösung anzubieten, die die Zusammenfassung des Spannzylinders mit dem Elektrodentragarm außerhalb des Bereichs vorsieht, der den hohen, beim Schmelzvorgang auftretenden Temperaturen ausgesetzt ist, der sich dann auch im Bereich starken Schmutzbefalls befindet.Against this background, the Invention primarily based on the task of offering a solution which summarizes the clamping cylinder with the electrode support arm outside of the area that provides the high that occurs during the melting process Exposed to temperatures, which is then strong in the area Infested with dirt.
Diese Aufgabe wird erfindungsgemäß mit einer gattungsgemäßen Einspannung gelöst, bei der Spannzylinder über seinen Boden lösbar in einer im Tragarm befindlichen, den Spannzylinder lageorientiert aufnehmenden Aufnahme fixiert ist. Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen 2 bis 6.This object is achieved with a generic clamping solved, at the tension cylinder over its bottom detachable in a position-oriented clamping cylinder in the support arm receiving recording is fixed. Embodiments of the invention result from the subclaims 2 to 6.
Mit der aus dem vorderen Bereich des Elektrodentragarms herausverlagerten Zusammenfassung des Spannzylinders mit dem Elektrodentragarm wird die Beeinträchtigung der die Zusammenfassung bewirkenden Schraubverbindungen durch den Schmelzbetrieb merklich begrenzt, wozu beiträgt, dass diese Schraubverbindungen sich im abgeschirmten Bereich des Elektrodentragarms befinden. Das Lösen der Schraubverbindungen ist deshalb nicht mehr mit bislang in Kauf zu nehmenden Problemen behaftet. Als ein weiterer gewichtiger Vorteil stellt sich bei der Lösung nach Anspruch 2 ein, dass der Spannzylinder im Bedarfsfall nach beiden Richtungen hin aus dem Tragarm entfernt und gegenläufig dann auch wieder eingesetzt werden kann. Damit bleibt dem Betreiber die Möglichkeit eröffnet, sich der Montageweise zu bedienen, die sich vor On als am geeignetsten erweist. Der Betreiber, d.h. die beigezogene Montagegruppe, kann zeitsparend dann auch parallel einerseits das Lösen des Spannbügels vom Zylinder und andererseits das Lösen der den Spannzylinder mit dem Elektrodentragarm zusammenfassenden Schraubverbindungen zugunsten des Schmelzbetriebes durchführen.With the one from the front of the electrode support arm moved out summary of the clamping cylinder with the electrode support arm, the impairment of those causing the combination Bolted connections noticeably limited by the melting shop, what does that contribute to these screw connections are located in the shielded area of the electrode support arm are located. The loosening the screw connections are therefore no longer available with increasing problems. As another weighty advantage yourself in the solution according to claim 2, that the clamping cylinder according to need removed in both directions from the support arm and then in opposite directions can also be used again. This leaves the operator with the possibility opened, to use the mounting method that is most suitable before On proves. The operator, i.e. the assembly group involved, can time-saving, then, in parallel, on the one hand, releasing the clamping bracket from the cylinder and on the other hand loosening of the clamping cylinder with the electrode support arm Carry out screw connections in favor of the melting shop.
