摘要:
A transfer for a forging or forming machine is disclosed in which the transfer assembly is journaled for pivotal rotation about an axis midway between adjacent die stations. The transfer fingers are mounted to extend radially from the pivot axis to gripper portions at the distal end. The structure provides a minimum rotational moment of inertia and dynamic imbalance to permit the transfer to operate at higher speeds. An embodiment is disclosed in which a parallelogram type mechanism connects between adjacent transfer assemblies to permit transfer without turning of the workpiece to one station and transfer with turning of the workpiece at another die station. The transfer drive is arranged on the side of the machine remote from the operator's position to provide better operator access to the machine. A simple connection is provided between the transfer and its drive which is automatically disconnected when the transfer is raised and which is reconnected when the transfer is again lowered to the operative position.
