Passion for successful joining

Designed for use in medium and large series production, the new generation of Rivkle® NEO P107 pneumatic tools are characterised by their ability to work with a force of 3 to 18 kN (M3 to M8 steel), ensuring efficient production of 36 Rivkle® threaded inserts and studs per minute. Their lightweight design (weighing only 2 kg) and noise level of less than 70 dB (A) makes them optimal for use in industrial environments. Ergonomics have been improved: equipped with a comfortable handle with a redesigned push button, and easy to use with both left and right hands, thanks to the central air connection. Automatic air return and force adjustment for each insert diameter ensure precise and easy operation, avoiding inappropriate adjustments and increasing precision during use.  They are compatible with existing Rivkle® tools.

Böllhoff’s Rivclinch® metal joining technology allows steel and stainless steel, aluminium and other non-ferrous materials to be joined together in a cost-effective and environmentally friendly way. The first step in this clinching process is to insert the materials into the die through the mould. As soon as the lower part of the material rests on the anvil of the die, it begins to flow sideways. In this process, the movable segments of the die then move outwards. The sliding of the materials generates the closing head. The die then returns to its starting position and the joined part can be removed. A spring brings the side pieces of the die together. The point deformation of the material creates a form and force fit joint. The Rivclinch® joining system can be adapted to existing presses and also be used in special machines. Single or multiple points can be produced simultaneously. The system can be integrated in manual tools, on robots and in work stations. In particular, the 100% pneumatic Rivclinch® 0706 IP system is suitable for joining large and thick sheet metal frames and profiles, such as ventilation ducts, door frames, etc., up to a total thickness of 4.5 mm.
