RIVSET®

RIVSET® self-pierce riveting is a process for a high strength mechanical joining of similar or combinations of materials whereby several layers can be joined without problem.

The joints:

• High-strength
• Suitable for visual inspection
• Reproducible, no pre-drilling
• Watertight and airtight
• For joining metallic and non-metallic materials
• For fastening dissimilar metals
• For various thicknesses of material
• For various strengths of material

All manufacturing industry has to join materials together. The importance and use of mechanical joining methods has increased significantly in recent years.

Benefits:

• No pre-drilling
• Especially approvite for hybrid joining
• High dynamic fastness
• Force and form-fit

The trend is towards the use of lightweight assemblies, galvanised and coated steels, high strenght steels, aluminium and plastics and combinations of these materials.
Particularly in the sheet-metal industry, RIVSET® self-pierce riveting has turned out to be very promising as an alternative and/or an addition to the previously dominating joining methods.

Material layers are joined by a hardened semi-tubular rivet in a single step with no pre-drilling, little noise and no emissions, producing an interlocked friction joint. The rivet is designed to penetrate through the top material and is spread under the influence of a die positioned below the lower material. As this lower material is not pierced the resulting joint is localised and impervious to gas and liquid.

How it works:

• Clamping device
• Punch
• Self-pierce rivet
• Upper workpiece
• Lower workpiece
• Die
