Abstract
A plate positioning apparatus for use with a punch machine having a number one workpiece stopper that moves left and right along the direction of the X axis and a number two workpiece stopper that moves to and fro along the direction of the Y axis perpendicular to the X axis, each workpiece stopper having its own motor. The number one workpiece stopper moving left and right relative to the punch along the direction of the X axis structured with a corner cutout on its inner leading edge so as to allow the punch to pass through. The number two workpiece stopper moves to and fro relative to the punch along the direction of the Y axis structured with a cutout section in the middle of its leading edge so as to allow the punch to pass through, the two cutout openings meeting at the forwardmost point of intersection to allow the punch to pass through.
