Abstract
Description
Die Erfindung betrifft eine Biegevorrichtung zum Einbiegen eines Sicherungsbleches eines Rotors einer Turbine, welches Sicherungsblech in einer entlang des Umfangs des Rotors erstreckenden Nut eingesetzt ist.The invention relates to a bending device for bending a locking plate of a rotor of a turbine, which locking plate is inserted in a groove extending along the circumference of the rotor.
Es ist bekannt, durch Sicherungsbleche die an einer Stirnseite des Rotors angeordneten Dichtelemente gegen eine Verschiebung in Umfangsrichtung zu sichern. Dabei werden an die Rotorscheibe zuerst die Dichtelemente in Umfangsnuten eingesetzt, wonach ein am Dichtelement angeordnetes Sicherungsblech in einer am Rotor vorgesehenen Ausnehmung eingebogen wird. Der Einbiegevorgang erfolgt manuell mit Hilfe eines einfachen Hebels, welcher in einer Hohlkehle der Rotorscheibe angesetzt wird und sich während des Einbiegevorgangs an diesem abstützt.It is known to secure by locking plates arranged on an end face of the rotor sealing elements against displacement in the circumferential direction. In this case, the sealing elements are first inserted into the circumferential grooves in the rotor disk, after which a locking element arranged on the sealing element is bent in a recess provided on the rotor. The bending process is carried out manually by means of a simple lever, which is recognized in a groove of the rotor disk and is supported during the bending process at this.
Nachteil der bekannten Montageanordnung ist, dass der zum Einbiegen des Sicherungsbleches verwendete Hebel unter Umständen von der Rotorscheibe seitlich abrutschen kann.Disadvantage of the known mounting arrangement is that the lever used to bend the locking plate may sometimes slip sideways from the rotor disk.
Aufgabe der Erfindung ist daher die Bereitstellung einer Biegevorrichtung zum Einbiegen eines Sicherungsbleches, mit der ein sicheres und jederzeit reproduzierbares Ergebnis für die umzubiegenden Sicherungsbleche erreicht werden kann.The object of the invention is therefore to provide a bending device for bending a locking plate, with a safe and reproducible at any time result for the locking plates to be folded can be achieved.
Die auf die Vorrichtung gerichtete Aufgabe wird mit einer Biegevorrichtung gemäß den Merkmalen des Anspruchs 1 gelöst.The object directed to the device is achieved with a bending device according to the features of claim 1.
Die erfindungsgemäße Biegevorrichtung umfasst eine zwei Abschnitte aufweisende Halterung, deren erster Abschnitt in die Nut des Rotors einsetzbar ist und deren zweiter Abschnitt bei in der Nut eingesetzter Halterung aus dieser hervorsteht sowie einen am zweiten Abschnitt drehbar gelagerten Hebel mit einer Anlagefläche zum Anlegen an einem umzubiegenden Schenkel des in der Nut eingesetzten Sicherungsbleches.The bending device according to the invention comprises a holder having two sections, whose first section can be inserted into the groove of the rotor and whose second section is at Inserted in the groove holder protrudes from this and a rotatably mounted on the second portion lever with a contact surface for application to a leg to be folded over the securing plate inserted in the groove.
Die Erfindung geht von der Erkenntnis aus, dass das Umbiegen eines Sicherungsbleches, welches in der Umfangsnut eines Rotors eingesetzt ist, besonders einfach und zuverlässig durchgeführt werden kann, wenn dazu eine Biegevorrichtung genutzt wird, welche während des Biegevorganges in ihrer Lage gesichert ist. Dies wird mit einer Biegevorrichtung erreicht, welche ebenfalls in derjenigen Nut eingesetzt ist, in der auch das Sicherungsblech montiert worden ist.The invention is based on the recognition that the bending over of a securing plate, which is inserted in the circumferential groove of a rotor, can be carried out in a particularly simple and reliable manner, if a bending device is used which is secured in position during the bending process. This is achieved with a bending device, which is also used in that groove in which the locking plate has been mounted.
Das vor dem Umbiegen rechtwinklige Sicherungsblech ragt mit einem seiner beiden Schenkel aus der Nut des Rotors heraus. Die am Hebel vorgesehene Anlagefläche dient zum Anlegen an denjenigen Schenkel des Sicherungsbleches, welcher aus der Nut des Rotors herausragt. Durch das manuelle Betätigen des Hebels wird dieser Schenkel teilweise um einen Vorsprung umgebogen, so dass dieser am Vorsprung beidseitig anliegt.The right-angled before bending locking plate protrudes with one of its two legs out of the groove of the rotor. The contact surface provided on the lever serves to abut against that leg of the securing plate which protrudes from the groove of the rotor. By manually operating the lever of this leg is partially bent around a projection so that it rests on both sides of the projection.
Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben.Further advantageous embodiments are specified in the subclaims.
Zweckmäßigerweise ist der Hebel um eine Drehachse schwenkbar, welche bei in Betriebslage befindlicher Biegevorrichtung senkrecht zur Radialrichtung des Rotors steht. Hierdurch wird erreicht, dass der umzubiegende Schenkel des Sicherungsbleches stets planungsgetreu umgebogen wird.Conveniently, the lever is pivotable about an axis of rotation which is perpendicular to the radial direction of the rotor when the bending device is in the operating position. This ensures that the leg of the security sheet to be bent is always bent to the exact planning.
Zweckmäßigerweise ist der erste Abschnitt der Halterung entlang der Erstreckung des Nutgrundes der Nut anlegbar. Eine sichere Betriebslage der Biegevorrichtung kann somit erreicht werden. Ein Verkippen der Biegevorrichtung wird aufgrund der flächigen Anlage des erstens Abschnittes am Nutgrund der Nut verhindert. Dies gewährleistet, dass die Drehachse des Hebels stets senkrecht zur Radialrichtung des Rotors ausgerichtet ist.Conveniently, the first portion of the holder along the extension of the groove bottom of the groove can be applied. A safe operating position of the bending device can thus be achieved. Tilting of the bending device is prevented due to the flat contact of the first section on the groove bottom of the groove. This ensures that the axis of rotation of the lever is always aligned perpendicular to the radial direction of the rotor.
Um eine korrekte Ausrichtung der Biegevorrichtung gegenüber dem Rotor zu erreichen, ist der erste Abschnitt der Halterung mit einer Ausnehmung versehen. Vorzugsweise ist die Ausnehmung in Umfangsrichtung betrachtet mittig am ersten Abschnitt angeordnet. Die Ausnehmung ist vorgesehen, um entweder den das Sicherungsblech haltenden Bolzen, welcher sich durch das Sicherungsblech erstreckt, aufzunehmen oder um demjenigen Schenkel des Sicherungsbleches aufzunehmen, welcher in der Nut eingesetzt ist. In der ersten Ausgestaltung weist der erste Abschnitt der Halterung eine Wandstärke auf, die der Breite der Nut, verringert um die Wandstärke des Sicherungsbleches entspricht. Für die zweitgenannte Ausgestaltung weist der erste Abschnitt eine Wandstärke auf, die der Breite der Nut entspricht. Mit beiden vorgenannten Ausgestaltungen kann die Biegevorrichtung in Umfangsrichtung des Rotors betrachtet gegenüber diesem exakt ausgerichtet werden, so dass zum Einbiegen des umzubiegenden Schenkels des Sicherungsbleches die Biegevorrichtung stets in einer vorgesehenen Betriebslage angeordnet ist. Die Biegevorrichtung sitzt dann spielfrei in der Nut.In order to achieve a correct orientation of the bending device relative to the rotor, the first portion of the holder is provided with a recess. Preferably, the recess is arranged centrally on the first section viewed in the circumferential direction. The recess is provided to receive either the locking plate holding bolt which extends through the locking plate, or to receive that leg of the locking plate, which is inserted in the groove. In the first embodiment, the first portion of the holder has a wall thickness which corresponds to the width of the groove, reduced by the wall thickness of the securing plate. For the second-mentioned embodiment, the first portion has a wall thickness which corresponds to the width of the groove. With both aforementioned embodiments, the bending device viewed in the circumferential direction of the rotor can be aligned with respect to this exactly, so that the bending device is always arranged in an intended operating position for bending in the leg of the securing plate to be bent. The bending device is then seated in the groove without play.
Zweckmäßigerweise weist der zweite Abschnitt der Halterung eine Wandstärke auf, die größer ist als die Breite der Nut.Conveniently, the second portion of the holder has a wall thickness which is greater than the width of the groove.
Die Erfindung wird anhand einer Zeichnung erläutert, wobei weitere Merkmale und Vorteile beschrieben sind.The invention will be explained with reference to a drawing, wherein further features and advantages are described.
