New self-pierce riveting technology
Innovations in lightweight construction in the automotive industry call for innovative fastening technologies.
This self-pierce riveting technology allows to join different materials in a single production step without pre-punching. The result is a high-strength as well as gas- and liquid-tight joint on the side of the die.
In the industry, the Böllhoff Group is considered as a competent partner being highly recommended in the future-oriented self-pierce riveting technology. The company has an extensive portfolio of fasteners, feeding technology, system integration and process monitoring. For many years, the automotive industry has put its trust in that comprehensive competence.
However, it is also about shaping the future. Today's lightweight construction and the related use of materials, ranging from aluminium to ultra-high-strength steels, require further development of established self-pierce riveting technology beyond proven technology limits. And again, we succeed.
The new RIVSET® HDX meets the requirements resulting from the well-known limits to the setting tool's setting force as well as the requirements regarding material mixes when joining ultra-high-strength steels and ductile materials. For this purpose, the fastener geometry has been optimised and the rivet hardness adapted.
Böllhoff realises stable joints using materials of tensile strengths up to 1,600 MPa and a sheet thickness of 1.8 mm in the top layer.
Modular and fully automatable
RIVSET® Automation H setting tools and machine components used in the process are modules to be configured for HDX use.
