  • Auto equalized dual pierce unit
    Patent number: 6237458
    Abstract: Disclosed is an automatically equalizing press for sequential operations on opposite sides of a workpiece. The press is designed to allow a pair of punch-anvil combinations to work on opposing sides of the workpiece without substantially deforming the workpiece prior to the final, e.g. piercing, operation. One tool from each combination is mounted on a slide block which is capable of movement independent of the other slide block. The slide blocks are operable by fluid actuated pistons.
