Abstract
A hydraulic press comprises a hydraulic drive for driving a die surface towards and away from a moving workpiece. The die surface and the hydraulic drive both move with the workpiece on rails. This is an improvement over prior art systems where only the die surface would move with the workpiece. In another aspect of the present invention a plurality of pickups also move with the hydraulic press. These pickups engage apertures in the workpiece to properly align cutting elements on the die with the workpiece. A control selectively actuates certain ones of the plurality of pickups to allow one to quickly change the size of elements formed by the die.
Claims12
A hydraulic press for a moving workpiece comprising:
- a die surface movable along an axis normal to a path of movement of a moving workpiece and carrying at least one cutting element, the cutting element having means for cutting an aperture in the moving workpiece;
- a base positioned parallel to and aligned with the die surface such that the moving workpiece moves between the base and the die surface;
- a plurality of independently selectively actuable pick-ups distributed along the path of movement of the moving workpiece with each pick-up having a piston operably engaging the workpiece by entry into the aperture of the moving workpiece and the pick-ups being slidably mounted for movement with the workpiece when engaged therewith and the die surface being connected to at least one of the pickups for movement therewith;
- control means for independently selectively actuating at least two of the pick-ups to engage the workpiece;
- and
- press actuating means for moving the die surface along the axis and toward the base to form the aperture in the moving workpiece when the piston of the at least one of the pick-ups is engaged with the moving workpiece.
