Dual-mode ultrasonic vibrator for drawing metal wire

Abstract

The invention discloses a dual-mode ultrasonic vibrator for drawing a metal wire, and belongs to the technical field of ultrasonic vibrators, which solves the problems of complexity in installation and manufacturing of an ultrasonic wire drawing vibrator, fragility of a ceramic chip, difficulty in industrial scene application and the like. The dual-mode ultrasonic vibrator comprises an amplitude-change pole, transducers and wire drawing dies, wherein the transducers and the wire drawing dies are arranged on the amplitude-change pole; the transducers comprise front end covers, back end covers,an even number of piezoelectric ceramics arranged between the front end covers and the back end covers and electrode plates which are arranged between the piezoelectric ceramics as well as between thepiezoelectric ceramics and the front end covers and the back end covers respectively, and the front end covers are connected with the amplitude-change pole; a wire through hole is formed in the center of the amplitude-change pole, and the amplitude-change pole comprises a transition area and wire drawing die mounting areas which are arranged on both ends of the transition area in the length direction of the wire through hole; two wire drawing dies are respectively arranged in the two wire drawing die mounting areas on both ends of the wire through hole, and the two wire drawing dies are installed in the same direction; and more than two transducers are arranged on the outer side wall of the transition area. The dual-mode ultrasonic vibrator is used for drawing the metal wire.

Description

technical field [0001] The invention discloses a dual-mode ultrasonic vibrator for wire drawing, which is used for wire drawing and belongs to the technical field of ultrasonic vibrators. Background technique [0002] At present, metal wires with a diameter of less than 8mm are generally produced by traditional ultrasonic drawing methods. However, for some difficult-to-process materials, due to their high strength and high hardness, the drawing speed is very low, less than 0.3m / s, frequent wire breakage and low efficiency during the drawing process, and the surface quality of the wire after drawing is poor and the dimensional accuracy Low. In order to obtain high-performance wire, hot drawing is required in the drawing process. The dimensional accuracy of hot drawing is poor, and cracks are prone to occur in drawing. After drawing, multiple dimensional calibrations and surface polishing are often required. [0003] In order to solve the above technical problems, the prior ...
