PURPOSE:To reduce the size of working equipment and working power and to form a tapered disc by forging radially and partially the disc which is a blank shape material placed on a die by means of a punch while rotating said disc. CONSTITUTION:When a working device is turned on, the stroke length and the number of blow set from an NC control device to a hydraulic servocontrol cylinder 10 are assigned. A punch 6 is actuated and the forging in the first working region is accomplished. Displacement is then measured with a displacement measuring device and the measured value is taken into an arithmetic processing device for data, by which the value is compared with the preset displacement. When the prescribed displacement is given, the punch 6 returns to the initial position and a die rotating angle is commanded from the control device to a servocontrol motor by which a die rotating device 9 is rotated. The rotating angle of the die is measured by a device for measuring the rotating angle and the measured value is taken into the arithmetic processing device, by which the value is compared. The stroke length and number of blow are commanded from the NC control device to the cylinder 10, by which the punch 6 is actuated and the succeeding working region is forged. |
