PURPOSE:To response quickly and to prevent malfunction in a combination press consisting of a double acting press and a transfer press, by detecting the angles of both presses and making the angles of the presses correctable. CONSTITUTION:A titled device consisting of an angle detecting means which detects the angles of a double acting press DA and a transfer press TR respectively, and a synchronizing angle controller AMP.SY which applies an angle correction command to either one press in accordance with the angle differences of the detected angles. When a speed difference is produced between said press TR and press DA, an angle difference is generated by synchronous control transformers CT1, CT2. The angle difference thereof is fed to the device AMP.SY, from which the angle correction command for the press DA alone is outputted. The speed of press DA is controlled by this and both presses DA, TR are operated synchronously. |
