RIVTAC® Automation P High-speed joining Innovative and flexible

Content Introduction Joining process Our competence – point for point

RIVTAC® Automation P Innovative by tradition Innovative industries require innovative partners. We are specialists in the field of mechanical joining technology. Thereby, we concentrate our know-how and experience in mechanical joining methods such as RIVSET® self-pierce riveting and the innovative RIVTAC® high-speed tack setting. Our technical competence is in constant demand – as customers continue to design new products, introduce new materials and develop production processes. The trend in the automotive industry, for example, is still to make vehicles more efficient through strict...

Joining process What is the concept behind RIVTAC® high-speed tack setting? In this innovative mechanical joining process, a nail-like auxiliary joining part, the tack, is accelerated to high speed and driven into the joining parts which are not pre-punched. The speed can be controlled through the joining pressure and depends on the materials to be joined as well as on the component thicknesses. At the beginning of the joining process, the ogival point of the tack displaces material extruding it for the tack shank. The joining part materials can flow into the straight knurlings of the shank...

RIVTAC® Automation P – The material combinations Variable material combinations become increasingly important, especially during the development of innovative automobile and car body concepts. RIVTAC® is particularly suitable for joints of aluminium, steel, plastics, non-ferrous metals as well as for mixed joints, multiple-layer joints and hybrid joints of these materials. Example material combinations in cross section Steel sheet / Steel sheet Aluminium sheet / Aluminium profile Joints: n Aluminium (pressure cast, extruded, sheet) n Steels n Plastics and fibre-reinforced plastics (e.g....

High-strength joints The following chart illustrates the joining strength of example material combinations under sheer and cross tension load. In addition to the pure steel and aluminium joints representing the joining technology, mixed joints are shown as well. Material cover sheet Material basic material Cross tension values (kN) Sheer load values (kN) The following figures show the load/deflection trends of similar steel/steel and aluminium/aluminium joints and also those of dissimilar aluminium/steel joints. You can easily recognise dependencies between the material/thickness...
