<p>The present invention relates to a method for the reconditioning of a cover plate (10) of a vane (1) of a turbomachine, in particular of a gas turbine, by means of a forming apparatus, a mounting portion with fastening elements (36, 37) being connected, from a vane root (34) of the vane (1), radially outwardly with respect to a rotary axis of the turbomachine, and an airfoil (30) being connected in the opposite direction. Further, a vane head (33) is connected to the airfoil (30) and the cover plate (10) is connected to the vane head (33), the cover plate (10) being bulged in the direction opposite to the vane root (34). In a first step, an analysis step, dimensions of the vane (1) in relation to the cover plate (10) are determined in respect of predefined reference points of the vane (1) by means of dimension analysis. If, after the analysis step, forming of the cover plate (10) seems necessary and possible on account of a comparison of measurement values from the analysis step with predefined dimension values, the bulged cover plate (10) is formed, in particular at least essentially pressed smooth, by pressing by means of the forming apparatus in a forming step. After the forming step, the cover plate (10) is preferably re-treated in one or more follow-up steps. The invention relates, further, to an apparatus for carrying out the method according to the invention.</p> |
