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...
In the article the process of transformation of longitudinal vibrations into radial ones was investigated; different designs of transducers (symmetric, partially symmetric and asymmetric) intended for continuous welding of thermoplastic materials were analyzed. Calculations based on mathematical modelling were presented; the design of the welding tool designed for continuous welding of thermoplastic...
The article presents results of theoretical investigations of formation of continuous joint in contact area of flat surface of the radiator with rotating surface of the pressure roller. The recommendation on the choice of pressure roller parameters and optimal amplitude of ultrasonic vibrations and broach speed for materials different in properties and thickness were developed on the basis of analysis...
The article considers the model of formation of weld seam of polymers by ultrasonic welding with ring-shaped working tool. Dependences of optimum amplitude of ultrasonic influence were ascertained according to diameter and width of the joint on the basis of the theoretical analysis of the process. The results of theoretical studies allow proposing the algorithm for optimum control of ultrasonic welding...
