Sonotrode and method for influencing the vibration behavior of a sonotrode

摘要

Sonotrode (218, 318, 418) of an ultrasonic welding device having a sonotrode body (224, 324) with sonotrode head (220, 320) with at least one work surface (230, 232, 330, 332) extending in the longitudinal direction of the sonotrode head for welding or / and or deforming and / or cutting at least one metallic weld metal, wherein the sonotrode head (220, 320) along the working surface (230, 232, 330, 332) has different cross-sections,. characterized in that the cross section of the sonotrode head (220, 320) in the frontally extending end region (244, 246, 344, 346) of the work surface (230, 232, 330, 332) is greater than in the central region of the work surface.
