Description: |
| Abstract
A press having a work positioning carriage for moving a workpiece horizontally along relatively transverse X and Y axes to position different areas of a workpiece at a work station. Lower forming tools are fixed at the work station and a lower stripper is mounted for vertical movement relative to the lower forming tools. Upper press tools are mounted on the press ram and operative when the ram is moved downwardly to force the workpiece downwardly over the lower forming tools and depress the lower stripper. The lower stripper is yieldably biased upwardly to raise the workpiece off the lower press tools when the upper press tools are raised. A work carrier is mounted for horizontal movement by the work positioning carriage and the work carrier has a workpiece support that is vertically movable relative to the work carrier. A master hydraulic actuator is operated during movement of the ram and is hydraulically connected to a slave fluid actuator mounted on the work carrier and connected to the workpiece support to raise and lower the workpiece support relative to the carrier in timed relation with movement of the ram. |
