The present invention relates to a self-piercing rivet setting apparatus capable of automatically changing a die for a rivet setting operation. The self-piercing rivet setting apparatus comprises a die assembly (18) including a plurality of dies (26-30) and a movable table (31), and a driving device for moving the die assembly. The driving device is operable to move the die assembly in a direction orthogonal to the axis of a punch (14) for allowing one (26) of the dies to be displaced to a position located axially below the punch. The driving device is also operable to move the die assembly in the axial direction of the punch. In a lowered position of the die assembly, the selected die can be fixed in a die mounting hole located below the punch. In this position, the punch is operable to drive a rivet into workpieces to fasten them together. <IMAGE> |
