Product Description
The ultrasonic transducer is also called the ultrasonic vibrator, and the whole after connecting the transducer and the horn is called the vibrator. It is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and amplifies the device through the front and rear radiation cover blocks matched with acoustic impedance.
Since the horn is a passive device, it does not produce vibration itself, but transmits the input vibration after changing the amplitude, completing the impedance transformation.
Ultrasonic transducers can produce regular vibration under electric field excitation, but the amplitude is generally about 10μm. Such an amplitude is not enough to directly complete the welding and processing procedures.
Therefore, after the transducer is connected to a reasonably designed horn, the amplitude of the ultrasonic wave can be changed in a large range, as long as the material strength is sufficient, the amplitude can exceed 100 μm.
Common materials for ultrasonic vibrators
1. Aluminum horn has high sound transmission efficiency, but the material strength is low, easy to crack and screw holes
2. The steel horn has high strength, but the acoustic impedance is relatively large
3. Titanium alloy horns have good overall performance, but the disadvantages are high price and difficult processing.
Ultrasonic transducer composition:
1. Middle piezoelectric ceramic element 2. Front and rear metal cover 3. Prestressed screw 4. Electrode sheet 5. Insulating tube
This kind of sandwich transducer generates stable ultrasonic waves when the load changes, which is a relatively basic and main method to obtain a power ultrasonic drive source.
According to different designs, the main forms of ultrasonic transducers are:
1. Column type 2. Inverted horn type 3 Steel back cover type 4. Intermediate aluminum sheet type
Mainly applicable to ultrasonic plastic welding machine, ultrasonic plastic welding, ultrasonic metal welding machine, ultrasonic cleaning machine, ultrasonic sonochemical equipment, etc.
