  • Workpiece shift apparatus for punch press
    Patent number: 6736039
    Abstract: A workpiece shift apparatus includes a bottom plate (10), a middle plate (40), and a top plate (70). A first pushing plate (26) is slidably attached on the bottom plate. The first pushing plate includes cutouts (30) in one edge thereof, and arcuate steps (32) on an opposite edge thereof. A first pushing means is installed on the bottom plate, and includes a handspike (19). The handspike sequentially engages in the cutouts to move the first pushing plate in a first direction. The steps thereby push the combined middle plate and top plate in a second direction perpendicular to the first direction. A second pushing plate (56) similar to the first pushing plate, and a second pushing means similar to the first pushing means are attached on the middle plate for pushing the top plate in the first direction.
