Abstract:
A nutplate die used in conjunction with a rivet forming device for securing a nutplate to a part by a plurality of rivets, said die comprising:a retention member adapted to be coupled to the rivet forming device to connect the die to the device; a first platen rigidly secured to the retention member; a plurality of punches rigidly secured to the first platen; a second platen including a plurality of punch bores extending therethrough, each punch bore being aligned with and receiving a separate one of the plurality of punches in a slidable engagement, said second platen further including a cavity shaped to hold the nutplate; and at least one biasing device positioned between the first and second platens, wherein activation of the rivet forming device causes the second platen to move toward the first platen against the bias of the biasing device so that the punches move through the punch bores and simultaneously form the plurality of rivets to attach the nutplate to the part.
