20khz ultrasonic Wire harness welding transducer 2000W ultrasonic welding aluminum transducer for welding machine
We call the whole of the ultrasonic transducer connected with the horn vibrator. Ultrasound transducer can produce regular vibration under appropriate electric field excitation. Its amplitude is generally about 10 micron. It is not enough to complete welding and processing directly. After connected with a reasonably designed horn, the amplitude of the ultrasonic wave can vary in a wide range. As long as the material strength is enough, the amplitude can exceed 100 microns. On the other hand, when the horn is in longitudinal expansion vibration, the movement direction of the particles on the left and right sides of a cross section in the middle is just opposite, which is equivalent to the existence of a relatively static joint. This node is called node, which is also the best fixed point of the oscillator. Deviation from the fixed node will reduce the working efficiency of the oscillator, commonly known as leakage wave. Generally speaking, the sound transmission efficiency of aluminium horn is high, but its material strength is low, it is easy to crack and screw hole slide; the strength of steel horn is high, but its acoustic impedance is relatively large; the comprehensive performance of titanium alloy horn is good, but its disadvantage is high price and difficult processing.

As the name implies, the ultrasonic horn can change the amplitude of the transducer. Amplifier is a passive device. It does not produce vibration itself. It only changes the amplitude of the input vibration and transmits it out. At the same time, it also completes the impedance transformation.

It can be said that as long as it is a common oscillator in the market, we all have production, and basically have stock. If customers have special requirements, we can provide products with the same accuracy and reliability as mass production within 15 days, provided we give samples or detailed technical parameters and requirements.
