Method and principle

RIVCLINCH® joining technology

With the clinching method, materials to be joined are first drawn into the die by the punch.
As soon as the lower material touches the anvil, it starts flowing laterally. In this process, the movable die segments are moved outwards. The flowing materials form the closing head. The punch then moves back into home position, the joined part can be removed, and the side parts of the die are pulled together by a spring.
Localised deformation of the material produces a positive-locking and friction-locking connection.
The RIVCLINCH® joining system can be adapted into existing presses or it can also be used in special machines. Single points and multiple points can be set at the same time. The clinching system can be integrated into manual machines, robots and stationary tools.
