SELF-PIERCING RIVET AND SELF-PIERCING RIVETING METHOD AND SELF-PIERCING RIVETED JOINT |
| 摘要 |
A self-piercing rivet for connecting high-strength steels. The rivet having a head which has a head diameter (DH); a shank which has a shank diameter (DS); and, located at the foot end of the shank opposite the head, the shank has radially outward a flat surface section and radially inward an axial recess defining an axial depth (LB). The ratio of axial depth (LB) of the recess to the shank diameter (DS) is smaller than 0.3. |

1. Self-piercing rivet (10) for connecting high-strength steels, with a head (12) which has a head diameter (DH), and with a shank (14) which has a shank diameter (DS), wherein, at the foot end (18) opposite the head (12), the shank (14) has an axial recess (22) which has an axial depth (LB), and wherein, at the foot end (18), the shank (14) has a flat surface section (20),
characterized in that the ratio of axial depth (LB) of the recess (22) to shank diameter (DS) is smaller than 0.3. |
