The development of ultrasonic vibrating system for continuous seam welding

Abstract

The article is devoted to the design of piezoelectric vibrating system providing transformation of longitudinal vibrations of the transducer into radial vibrations of welding instrument made in the form of diverging cone, on the external surface of which at the part of larger diameter cylindrical working surface is made. The presence of cylindrical working surface at the provision of rotation of vibrating system allows to carry out continuous welding of list and film thermoplastic materials. The design on the base of mathematical modeling and experimental studies of produced constructions let develop vibrating system providing ultrasonic influence with the amplitude of no less than 30 μm, if the diameter of radiating surface is 92 mm and its width is 4 mm.
