<p>A profile-steel shear usable for cutting or punching profile-steel members has a pair of relatively fixed, spaced-apart, and parallel frame plates flanking a drive plate having a lower end edge engaging the upper end edge of a blade-type work plate. The outer faces of the drive and work plates are formed adjacent the abutting ends with grooves parallel to these abutting ends. U-shaped clips or elements each have one leg engaged in a respective groove of the drive plate and another leg engaged in a respective groove of the work plate so that these U-shaped elements secure the work and drive plates together for relative displacement by means of a hydraulic actuator normally situated atop the frame plates. These U-shaped elements are releasably retained on the work and drive plates with their legs in the respective grooves by means of screws engaged through them and with the work or drive plates.</p> |
