Abstract

PURPOSE: The forging press which is able to perform forging almost continuously by installing a manipulator to alternately carry out forging with an actuator on the front of several forging press housing which commonly have a part of the frame, and has got rid of the waiting time of tools, etc.

CONSTITUTION: This forging is not performed at the same time with both the forging press housings 1-2, 2-3, but is carried out alternately. For instance, in case forging is made with the fluid pressure cylinder 5, material is grasped with the tongs equipped with the manipulator 10 on the rail 12, pressure oil is fed to the cylinder 5 from the oil pressure source 7 by changing the change-over valve 6, and forging is carried out with the upper and lower anvils in the same way as usual. And while forging is performed with the cylinder 5, at the side of the fluid pressure cylinder 4, the anvils which are set at the side of the frames 1, 2 and the tools are replaced by operating the tool replacement truck 8, and the preparations for the next forging are made. As mentioned above, forging is performed by alternately changing the direction of the manipulator 10, and changing the tool and the anvil in order, the manipulator 10 detaches the moldings after molding the material to the fixed shape and grasps the next material, and the same forging as mentioned hereinabove is carried out again.
