Abstract
A self-contained, self-actuating corner radius punch and die machine is described including a plurality of spaced apart side-by-side cutting edges arranged in transverse alignment above a worktable. A motive power actuator, e.g., a hydraulic cylinder is mounted below the worktable with its actuator rod extending upwardly through the table and being connected to the punch. A guide is provided for preventing the punch from tilting about a horizontal axis and a stiffening plate is secured to the punch to rigidify the structure and to serve as a support for the guide.
