ABSTRACT:
The invention is a system for use in a single-anvil hydraulic press or compression system for automatically selecting and changing both the upper and lower tooling. The system is installed between the upper and lower compression anvils of a hydraulic press. The upper portion includes a set of holders for upper tools and adjacent orientation structures or jaws. The upper tool holders and jaws are mounted on a horizontal member that may be moved such that one of the upper tools is "selected" by being placed immediately below the upper anvil of the press. As part of this selection process, the anvil removes the tool from the selected holder, and holds it using pneumatic suction. Then the horizontal member shifts over so that the upper anvil is situated directly above the adjacent orientation structure for that tool. To switch to a different upper tool, the horizontal member again moves the (empty) holder below the upper anvil, whereupon the pneumatic suction is removed causing the tool to drop into the holder. The horizontal member then moves to the newly selected tool holder and removes the tool therefrom using the pneumatic suction. Then the horizontal structure shifts over so that the upper anvil is situated directly above the adjacent orientation structure for the newly selected tool.
