Abstract

The invention provides a method for forming a metal wire based on ultrasonic vibration and belongs to the technical field of ultrasonic application. The method comprises the following steps: fixing one end of the metal wire at one end of an objective table of ultrasonic equipment, and pulling the other end of the metal wire to a to-be-fixed position; placing the metal wire in a groove at the front end of an ultrasonic tool head by virtue of regulating an X-directional movement guide rail of the ultrasonic equipment and a Z-directional movement guide rail of the ultrasonic equipment, wherein the groove is used for fixing the metal wire; processing for 1-5 minutes under the ultrasonication with the frequency of 20-100kHz and the vibration amplitude of 2.5-60[mu]m, releasing the metal wire after the metal wire generates plastic deformation, thereby realizing small-stress formation of the metal wire. By virtue of an ultrasonic vibration forming system, the metal wire generates plastic deformation under the action of high-frequency cyclic load, and the forming purpose is achieved. During the process, forming and residual stress release are realized simultaneously, and the technical method is high in forming efficiency and less in residual stress.

Description

technical field [0001] The invention relates to the technical field of ultrasonic applications, in particular to a method for forming metal wires based on ultrasonic vibrations. Background technique [0002] Ultrasound refers to mechanical waves with a vibration frequency above 16kHz. The existing ultrasonic vibration aging method uses ultrasonic excitation to make the lattice of constituent atoms absorb mechanical energy, thereby reducing or homogenizing the residual stress of the component. This method is widely used in the application of eliminating the residual stress of large-scale welded parts on ships and aircrafts. It has the characteristics of environmental protection, energy saving, safety and pollution-free, more flexible and convenient use on the construction site, simple processing technology, and stable and reliable effects. [0003] The above method proves that the ultrasonic vibration aging technology can reduce or homogenize the residual stress of metal com...
