Abstract
The invention discloses an ultrasonic vibrator for drawing titanium and titanium alloy wires, and belongs to the technical field of ultrasonic vibrators, which solves the problems of low drawing speed, low drawing precision and the like when the titanium and titanium alloy wires are drawn by adopting hot drawing in the prior art. The ultrasonic vibrator comprises an amplitude-change pole, a transducer and a wire drawing die, wherein the transducer and the wire drawing die are arranged on the amplitude-change pole, the transducer comprises a front end cover, a back end cover, an even number ofpiezoelectric ceramics arranged between the front end cover and the back end cover and electrode plates which are arranged between the piezoelectric ceramics as well as between the piezoelectric ceramics and the front end cover and the back end cover respectively, and the front end cover is connected with the amplitude-change pole; and a wire through hole is formed in the center of the amplitude-change pole, the wire drawing die is arranged on the amplitude-change pole on one end of the wire through hole, and the transducer is arranged on the other end of the wire through hole. The ultrasonicvibrator is used for drawing the titanium and titanium alloy wires.
Description
technical field [0001] An ultrasonic vibrator used for drawing titanium and titanium alloy wires is used for drawing titanium and titanium alloy wires, and belongs to the technical field of ultrasonic vibrators. Background technique [0002] Because the yield strength ratio of titanium alloy is as high as 0.95 and the deformation resistance is large, titanium and titanium alloy wires with a diameter of 2 mm to 10 mm are generally produced by hot drawing, and traditional ultrasonic technology is not used. However, due to the poor thermal conductivity of titanium alloy, the springback of hot drawing is serious, the drawing speed of titanium alloy wire is lower than 0.5m / s, the wire breakage is frequent during the drawing process, the efficiency is low, and the surface quality of the wire after drawing is poor and Dimensional accuracy is low. In order to obtain high-performance wires, titanium alloy wires need to undergo multiple dimensional calibration and surface polishing a...
