摘要： The present invention concerns an ultrasonic welding installation comprising an ultrasonic vibration unit having a sonotrode and a converter, wherein the sonotrode and the converter are arranged in mutually adjacent relationship along a longitudinal axis and the ultrasonic vibration unit can be caused to resonate with an ultrasonic vibration in the direction of the longitudinal axis with a wavelength λ, wherein there can be provided an amplitude transformer arranged between the sonotrode and the converter, wherein there is provided a holder for holding the ultrasonic vibration unit. To provide an ultrasonic welding installation having a holder which allows simple adjustment of the ultrasonic vibration unit and simple replacement thereof it is proposed according to the invention that the holder has a clamping device which is reciprocable between an opened position in which the ultrasonic vibration unit can be removed from the holder and a closed position in which the clamping device comes into contact with the ultrasonic vibration unit and exerts a force on same so that the ultrasonic vibration unit is held.

摘要： The present invention relates to an ultrasonic vibration system (1) comprising a sonotrode which has two sonotrode end faces (8, 8′) and a circumferential lateral surface that connects said sonotrode end faces (8, 8′) with each other. The sonotrode has an elongate core element (2) and at least one wing element (3, 4), each core element (2) and wing element (3, 4) longitudinally extending from the one sonotrode end face (8) to the other sonotrode end face (8′). The wing element (3, 4) has a sealing surface (7) which is designed to be in contact with a material for the purpose of processing same and which is connected to the core element (2) via a plurality of longitudinally interspaced connecting portions (5, 6). The ultrasonic vibration system further comprises a converter (9) which is optionally connected to the sonotrode via an amplitude transformer (11). According to the invention, the converter (9) or the amplitude transformer (11) is connected to the lateral surface of the sonotrode

摘要： The present invention concerns an ultrasonic vibration unit having a converter (1) for converting an electric ac voltage into a mechanical ultrasonic vibration and a sonotrode which is vibrationally coupled to the converter (1), wherein the sonotrode and the converter (1) are matched to each other in such a way that the ultrasonic vibration unit can vibrate with a natural frequency f, in which a standing longitudinal wave having at least one vibration node and at least two vibration antinodes is formed within the ultrasonic vibration unit. To provide an ultrasonic vibration unit in which the parasitic vibrations which usually occur in operation with a working frequency are slight or do not occur, wherein at the same time the actual working frequency is not attenuated, it is proposed according to the invention that there is provided a damp vibration absorber unit (2) connected to the ultrasonic vibration unit by way of a coupling element (3), wherein the coupling element (3) is connected to the ultrasonic vibration unit at a vibration node, wherein the vibration absorber unit (2) is connected to a damping element (4) which is so adapted that it damps a vibration of the vibration absorber unit (2).
