Wobble riveting

Wobble riveting is a direct riveting process for manufacturing high-quality rivet connections.

Sequence:

The shaping process is performed with a riveting die, the axis of which is at a constant inclined angle with respect to the riveting axis.

The riveting process is initiated by an axial movement of the riveting die in a vertical direction (triggered by the riveting press), combined with a permanently circling movement (wobbling movement on a circular track).

This causes the material to start flowing both axially and tangentially, and it undergoes cold deformation. As a result of the punctiform contact, the deformation is in line with the material properties and the rivet surface undergoes little stress. Despite the high deformation power, the tools are subjected to little stress.
