Oscillating system for a joining device, joining device and use thereof

摘要

The invention relates to a vibration system for a joining device, with a vibration converter, which can be connected to a vibration generator, and with a sonotrode (32), which is connected to the vibration converter in a vibration-transmitting manner, and in which a standing, longitudinal wave can be formed Sonotrode (32) has a tapered region (70) within a last quarter (A / 4) of a wavelength of the standing, longitudinal wave located at an end facing away from the vibration converter, as well as a joining device and a use of the vibration system.
