Process for connecting workpieces and pressing device therefore

摘要

The pressing device has two or more pressing jaws (21,22) and a jaw drive (7) controlled by a control unit which has a power control device (35) which produces a power path for the drive so that the pressing jaws have at least towards the end of pressing a lower kinetic energy than without power control. The power control device during a first phase of the pressing process where an idle stroke is overcome produces a power path where the power is reduced so that the pressing jaws have at the end of this phase a lower kinetic energy than without power reduction.
