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.

Claims4

Dependent claims

A plate positioning apparatus for use with a punch machine having a punch, comprising:

a number one workpiece stopper movable back and forth along an X axis and having its leading edge perpendicular to the axis of motion and further having a cutout space on the inner corner of its leading edge,
(b) a number one motor for moving said number one workpiece stopper back and forth along the X axis and controlling said number one workpiece stopper so that its leading edge at its forwardmost position is in front of the punch of the punch machine,
(c) a number two workpiece stopper movable along a Y axis perpendicular to the X axis, having its leading edge perpendicular to the axis of motion, and having a cutout section in its leading edge adequate to allow the passage of the punch,
(d) a number two motor for moving said number two workpiece stopper to and fro along the Y axis and controlling said number two workpiece stopper so that the cutout section in its leading edge at its forwardmost position is directly under the punch, and
(e) a control apparatus for independently operating said number one and number two motors.
