Patent ID: 7946145

Claim:
A method of operating a forging press having: an upper upstream forging die and a lower upstream forging die in an upstream work space, one of the dies being movable in the upstream space toward and away from the other of the dies between an open position and a closed position; a conveying device having a vertically and horizontally displaceable grab movable in the open position of the upstream dies between an inner position in the work space between the dies engaging a workpiece in the lower die and an outer position out of the work space; and a spraying device including a vertically and horizontally displaceable sprayer movable between an inner position in the work space between the dies and an outer position out of the work space, the method comprising the steps of sequentially: a) after a forging operation and movement of the dies into the open position, moving the grab from the respective outer position into the respective inner position, engaging the grab with a workpiece in the lower die, raising the workpiece out of the lower die with the grab, and then moving the workpiece and the grab from the respective inner position toward the respective outer position; and b) as the grab, after moving into the respective inner position, engages the workpiece and lifts it and then moves with it from the respective inner position to the respective outer position, moving the sprayer synchronously from the respective outer position to the respective inner position, thereby engaging the sprayer between the dies, and c) thereafter spraying the dies with the sprayer.
