The invention relates to a bending device for bending in a locking plate of a rotor of a turbine, by means of which a reliable fastening of the locking plate is carried out. The bending device comprises a mounting which has two sections, the first section of which is inserted into the groove of the rotor, and the second section of which, with the mounting inserted in the groove, projects from this groove. By means of a lever, which is rotatably mounted on the second section, the locking plate can be reliably bent over for securing a bolt against loss.

The invention claimed is: 1. A bending device for bending a locking plate, positionable in a groove of a rotor of a turbine, that is to be bent over, the groove extending along a circumference of the rotor, comprising: a mounting having first and second sections adjacent to each other, the first section insertable into the groove of the rotor, and the second section, projecting from the groove when the mounting is inserted in the groove, and a lever that is rotatably mounted on the second section of said mounting with a contact surface for bearing upon a leg of the locking plate that is to bent over after the locking plate is inserted in the groove. 2. The bending device as claimed in claim 1, wherein the lever is pivotable around a rotational axis and, is perpendicular to the radial direction of the rotor when the first section is inserted in the groove. 3. The bending device as claimed in claim 2, the when the bending device is in the operating position, the first section lays along the extent of the groove base of the groove. 4. The bending device as claimed in claim 3, wherein the first section of the mounting is provided with a recess. 5. The bending device as claimed in claim 4, wherein the recess is positioned in the middle on the first section as seen in the circumferential direction. 6. The bending device as claimed in claim 5, wherein the first section has a wall thickness which corresponds to the width of the groove, reduced by the wall thickness of the locking plate, and the recess has a width in the circumferential direction which corresponds at least to the diameter of the bolt. 7. The bending device as claimed in claim 6, wherein the second section has a wall thickness greater than the width of the groove. 8. The bending device as claimed in claim 5, wherein the first section has a wall thickness which corresponds to the width of the groove, and the recess has a width which corresponds to the width of the locking plate.
