Abstract: A C-shaped tool holder has a first leg and a second leg that is arranged opposite to the first leg, a connecting piece by which the first leg and second leg are connected with each other at a respective connecting end. An operating end of the first leg serves for fastening a punch in the direction of the operating end of the second leg, and an operating end of the second leg serves for fastening a die dome wherein an offset difference due to a gravity-caused offset between the operating ends of the first and second legs can be minimized by at least one compensating element which is arranged at one or more of the following elements: the first leg, the second leg or the connecting piece.

Abstract: 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.
