Problems solved by technology

The amplitude amplification factor of the traditional solid horn with variable cross-section is limited, and it often cannot meet the requirements for large-amplitude power ultrasonic applications.
The first solution is to cascade multi-stage horns together, the second is to increase the input power of the transducer, the first method will increase the cost, and the second method will shorten the transducer service life

Abstract

Provided is a catenary suspension linear ultrasound longitudinal vibration amplitude-change bar with a hole formed in the axial direction of the output end. The rectangular through hole is machined in the inner side of the small end in the axial direction of the center line of the amplitude-change bar, the distance t between the outer wall of the rectangular through hole and the small end is 2 mm-0.18 mm, the length of the amplitude-change bar is L, and according to the geometric shape, the amplitude-change bar is a rod-like body with the two end faces being parallel planes perpendicular to the center line and the side face being a hyperbolic cosine revolution surface. Because the rectangular through hole is formed in the position, away from the output end by a certain distance, in the axial direction of the center line of the catenary suspension linear amplitude-change bar, when the amplitude-change bar works at a longitudinal vibration resonant frequency position, the output end further has excited bending vibration components besides longitudinal vibration components of the amplitude-change bar; due to the superposition of the longitudinal vibration components and the bending vibration components, the amplitude amplification coefficient of the holed conical amplitude-change bar is increased by 1.68-3.3 times compared with that of a solid conical amplitude-change bar, and working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical vibration, and in particular relates to an ultrasonic horn of an ultrasonic transducer. Background technique [0002] Ultrasonic horn can be widely used in chemical industry, petroleum, cleaning, mechanical processing, food, medicine, automobile, instrumentation, textile, mechanical processing (such as turning, drilling, grinding, plastic welding, metal welding) and other fields. It is an important component in the ultrasonic vibration system. It is connected with the ultrasonic transducer. Its main function is to amplify the particle displacement or velocity of the mechanical vibration output by the ultrasonic transducer, and to concentrate the ultrasonic energy on the area of ​​the output end of the horn. It plays the role of energy gathering, also known as gear lever or energy concentrator. Usually the amplitude of the output end of the ultrasonic transducer is small, only a few microns, an...
