Abstract:
A two stage ram cover-plate assembly tool adapted for use with a press machine, for deforming an expandable cover-plate to enclose one end of a movable socket housing having a protruding pressure plate, and to establish a predetermined wear indicator distance between said cover-plate and a portion of said pressure plate, comprising:a cylindrical housing having a central axis;a first adapter seated concentric to said central axis, adjacent a first end of said cylindrical housing, said first adapter having an axial bore of a first diameter and configured to secure said two-stage ram to said press machine;a second adapter secured to said housing concentric to central axis and opposite said first adapter, said second adapter having an axial bore of a second diameter and configured to receive a removable stop-out plate configured to expand said cover-plate;a working face on said removable stop-out plate for expanding said cover-plate under a first load;a second-stage deflector axially disposed within said cylindrical housing, said second-stage deflector having a posterior end fitted with said first diameter axial bore of said first adapter, and an anterior end fitted within said second diameter axial bore of said second adapter, said anterior end configured to deform said cover-plate, said anterior end of said second stage deflector for deforming said cover-plate under a second and greater load to a predetermined position, a distance between said deformed coverplate in said predetermined position and an uppermost surface of said pressure plate corresponding to said predetermined wear indicator distance; anda plurality of compressible spring members disposed concentrically within said cylindrical housing, said compressible spring members preloaded to exert an expansive force on said first and second adapters.
