  • Automatic nutplate die
    Patent number: 6421900
    Abstract: An automatic nutplate die (70) that is used to align a plurality of rivet punches (116, 118) with rivets (24) being used to secure a nutplate (22) to a part (26) by a rivet squeezer (62). The nutplate die (70) includes a nutplate platen (74) and a punch platen (76) secured to each other by a pair of stripper bolts (78, 80). The stripper bolts (78, 80) included threaded portions (104,108) that are threaded into the punch platen (76), and heads (96, 100) that are positioned within counter-sunk bores (98, 102) in the nutplate platen (74). A spring (84, 90) is positioned on the shaft (86, 92) of each of the bolts (78, 80). The rivet punches (116, 118) are rigidly secured to the punch platen (76) and are slidably engaged within opposing bores (120, 122) in the nutplate platen (74). The nutplate platen (74) includes a cavity (124) that accepts the nutplate (22) so that holes in the nutplate (22) are aligned with the punches (116, 118).
