Torsten Draht

A joining device, in particular a self-piercing rivet tool, is disclosed that is operated with the assistance of different drive steps. These drive steps comprise at least one movement step with a fast punch speed, and a power step with a low punch speed and strong punch force. In combination with the joining device, a clamping device module is use that, based on the at least one spring in the clamping device module, generates discernible threshold values in the force/punch path diagram, with the assistance of which a switchover between different drive steps of the joining device is activated. Moreover, the present disclosure relates to a joining method for the above-described joining device.
