Abstract
PURPOSE: To make possible the correction of the circular material into true roundness to be easily, easily, exactly carried out, by constituting so as to be able to correct the distorted part of the circular material by pressing from both of inside and outside using two stationary press pins inserted into the pin holes of arbitrary couples and the moving pressing parts.
CONSTITUTION: Correspondingly to the circumference of the circular material 6 to be corrected, and the condition of the distorted part to be corrected, two stationary press pins 4, 4, are inserted into the suitable couples of pin pholes 5, 5, and are fixed. When the distorted part is concave, pins 4, 4, are fixed to the pin holes 5, 5, on the left side, and the concave distorted part of the circular material 6 is set between the right side of pins 4, 4, and the left side of the pressing parts 21; at the same time, the circular material 6 is set to the same circular arc type gauge (unillustrated); next, the right side hydraulic cylinder 3 is actuated for moving the moving pressing parts 2 in the direction of the full line arrow; and the circular material 6 is pressed by the pressing parts 21 until the distorted part conincides with the gauge. When the distorted part is convex, the parts 2 is moved in the direction of the broken line arrow by the left side cylinder 3, and the circular material 6 is pressed and corrected by the left side of pins 4, 4, and the right side of the pressing parts 21.
