Устройства для уменьшения трения при волочении и сонохимической очистки проволоки от смазки

Abstract

Article is devoted to reduce friction during drawing wire at the expense of ultrasonic axial vibration the portage, sonochemical cleaning it from technological lubricant type residues in aqueous solutions of detergents by acoustic cavitation generated by energy dissipation of elastic vibrations in the washing solution, as well as the design of ultrasonic devices for the implementation of these technology. At the expense of axial ultrasonic oscillations for the reducing friction on the surface of the wire is formed additional hardening. Cleaning - it removal from the surface of the wire technological lubricant and under-lubricant layer before polishing, coppering and applying corrosion-resistant coatings in the manufacture of welding wire or before applying insulation in the production of electrical wires. It can be performed as a separate process, which implemented on the rewinding machine. A device may be used as a part of drawing machine, or together with the rewinding machine. The paper presents the principles of calculation of the integrating waveguide transformers - essential elements for controlling devices with ultrasonic oscillations and their industrial use. They allows to integrate the power of several of ultrasonic transducers, does not obstacles to the rectilinear trajectory of drawing wire. Is shown the original design of small cavitation reactors which located inside transformers and are providing sufficiently sonochemical effects on cleaning solutions.
