| 摘要 |
The invention relates to an ultrasonic welding apparatus for ultrasonic machining of a material, having at least two sonotrodes and a converter device, which converts an electrical AC voltage into an ultrasonic vibration and sets the at least two sonotrodes in ultrasonic vibration, the at least two sonotrodes being arranged in such a manner that the material to be machined is arranged between them during machining and can at the same time be machined by the at least two sonotrodes. To specify an ultrasonic welding apparatus that allows effective material machining without an undesirable interaction occurring between the two sonotrodes, the converter device according to the invention excites the first sonotrode at a frequency fs1 the second sonotrode at a frequency fs2, fs2 being greater than fs1. |
