Rivet base detection devices

The NHE recognizes the rivet projection (U), serves as a hold-down device and helps to reliably recognize components before forming with tolerance errors or missing components. The NHE combined with the HPP-25 (necessary for most riveting modes) makes it possible to form relative to the workpiece height in order to compensate to a large extent for component variations. Control criteria such as final head height (H), rivet time (T) or formed rivet shank height (S) can be defined with varying work piece height. Additionally, the NHE allows process monitoring of many different criteria.

As result of the HPP-25 monitoring capability, inspection of components pre or post forming can be eliminated. Additional inspection Stations can be eliminated and production cost can be reduced.
