Abstract (en)

A self-piercing rivet fastening apparatus (1) drives a self-piercing rivet (10) having a large-diameter head portion (11) and a hollow leg portion (12) into member to be fastened (41, 42), and fastens it. The die is equipped with a die body (30) and a center pin (50). The die body (30) has an upper surface (31), a recessed portion formed inside the upper surface and a center pin hole (34) which passes from the center portion of the concave portion to the lower end portion (37). The center pin (50) is axially movably supported in the center pin hole and has a shaft portion (52). It is possible to have a pin flange (53) at one end portion of the shaft portion. A spring (55) pushes the center pin upward. When fastening the self-piercing rivet, the member to be fastened pushes the center pin and enters the center pin hole. After fastening, the center pin pushes out the member to be fastened.
