Abstract: A method is provided for reconditioning a turbomachine vane cover plate, by a forming apparatus. The vane having a mounting portion, an airfoil extending radially outward therefrom and a vane head connected to the airfoil. The vane also having a cover plate connected to the vane head, bulged in a direction opposite to the root. In a first analysis step, dimensions of the vane in relation to the cover plate are determined in respect of predefined reference points. If, thereafter, forming of the cover plate seems necessary and possible based on comparison of measurement values from the analysis step with predefined dimension values, the bulged cover plate is formed, at least essentially pressed smooth, by pressing by the forming apparatus in a forming step. After the forming step, the cover plate is re-treated in one or more follow-up steps. An apparatus is also provided for carrying out the method.
Abstract translation: 提供了一种通过成形装置来修复涡轮机叶片盖板的方法。 叶片具有安装部分，从其径向向外延伸的翼型件和连接到翼型件的叶片头。 叶片还具有连接到叶片头的盖板，沿与根部相反的方向凸出。 在第一分析步骤中，关于预定义的参考点确定叶片相对于盖板的尺寸。 此后，如果根据分析步骤的测量值与预定义的尺寸值的比较，盖板的形成似乎是必要的，并且可以通过成形设备的压制而形成至少基本上平滑的膨胀盖板 步。 在成形步骤之后，在一个或多个后续步骤中重新处理盖板。 还提供了一种用于执行该方法的装置。
