Self-aligning riveting method

Abstract:

Provided are self-aligning riveting tools and methods of utilizing such tools for installing rivets. A tool includes an aligning sleeve, which is slidably coupled to a first die. Furthermore, the tool includes a die holder, which is slidably coupled to a second die. During operation, the aligning sleeve is positioned over the rivet head thereby axially aligning the first die relative to the rivet, even before the first die contacts the rivet head. The second die contacts the rivet shank end thereby axially aligning the rivet relative to the second die and the die holder. Advancing the die holder toward the first die first clamps the rivet in the tool and then proceed with forming the rivet tail. The rivet remains coaxial with both dies during all of these operations.
