Ultrasonic joining tool for materials of all types has position and shape of individual boundary regions selected to minimize flexural vibrations of transformer towards materials to be joined

摘要

The tool has an elongated transformer with a head part and a coupling surface to which at least one ultrasonic source is attached and a foot part with at least one contact area for the materials to be joined. The coupling surface and the transformer side walls that emanate from it are flat. The position and shape of the individual boundary regions are selected to minimize flexural vibrations of the transformer towards the materials to be joined. The tool has an elongated transformer (1) with a head part (2) and a coupling surface (9) to which at least one ultrasonic source (10) is attached and a foot part (3) with at least one contact area (11-13) for the materials to be joined. The coupling surface and the side walls of the transformer that emanate from it are flat and the position and shape of the individual boundary regions (14) are selected to minimize flexural vibrations of the transformer towards the materials to be joined. AN Independent claim is also included for the following: a method of manufacturing a transformer for an inventive device.
