    Abstract: A self-piercing riveting (SPR) system includes a top sheet and a bottom sheet. The top sheet is layered above the bottom sheet and are disposed between a die and a blank holder. The SPR system further includes a barrier disposed between the bottom sheet and the die, wherein the barrier is configured to reduce stress concentrations during formation of a joint between the top sheet and the bottom sheet. The barrier may has a thickness between 0.8 mm and 1.0 mm and is made from a cold formed or a dual phase steel alloy.

  • SELF-PIERCING RIVETING DIE FOR MAGNESIUM ALLOY DIE CASTINGS
    Publication number: 20220305546
    Abstract: A self-piercing riveting (SPR) die includes a die body including an outer surface, a lower surface that is parallel to and offset from the outer surface, and a side surface that circumscribes the lower surface. A distance between the lower surface and the outer surface is less than or equal to approximately 1.2 mm. An angle between the side surface and the lower surface is within a range between approximately 45 and 90 degrees. An inner diameter of the outer surface is within a range between approximately 9 and 13 mm.
