  • Workpiece shift apparatus for punch press
    Patent number: 6626281
    Abstract: A workpiece shift apparatus includes a bottom plate (30), a middle plate (50) slidably attached on the bottom plate, and a top plate (80) slidably attached on the middle plate and defining cutouts (86). A first pushing means is installed on the bottom plate and includes a first piston cylinder (32), a first piston rod (34), and a first handspike (38). The combined middle plate and top plate is moveable in a first direction by the first pushing means actuating the first handspike to push the middle plate.
