Abstract (en)
[origin: WO2017032959A1] An ultrasonically vibrated die (1) comprises a generally cylindrical die ring (2) supported by a coaxial resonant mounting tube (4). The die ring (2) is vibrated in a radial bending (RB0) mode of vibration, in which an end surface (5) of the die ring (2) oscillates between a concave and a convex state. The mounting tube (4) joins the end surface (5) of the die ring (2) at a radius R where the amplitude of the oscillation of the end surface (5) is at a minimum, in order to reduce transmission of the vibration into the mounting tube (4).
