Abstract

A press with a press lock includes a press frame, a press ram slidably connected with the press frame, a rack fixedly connected with the frame, a pinion block connected with the ram, a pinion actuator operatively interconnected between the ram and the pinion block, and a control operatively connected with the pinion actuator. The press frame defines a stroke length and the press ram slides along the stroke length. The rack also extends along the stroke length, and the pinion block slides generally perpendicular to the stroke length, between open and closed positions of the press lock. The pinion block is also substantially fixed with the ram, relative to movement in a direction along the stroke length. The pinion block further engages the rack in the closed position, fixing the ram at a predetermined location along the stroke length, and disengages the rack in the open position, not inhibiting sliding of the ram along the stroke length. Finally, the pinion actuator slides the pinion block between the open and closed positions.
