Self-Pierce Rivets

Used by Audi on their aluminium cars the Self pierce rivet is gaining popularity as a joining method. At Warwick their application for aluminium extrusion joining has been investigated as well as some fundamental research into the forces applied during the riveting process. Current work is investigating the use of toolchangers with robotic self pierce rivet setters. The difficulties perceived here are the high pressure connectors for the hydraulic setters.
