1500W 20KHZ Small Ultrasonic Plastic Welding Transducer And Generator For Metal Welding Machine

When the ultrasonic plastic welding transducer applies voltage to the two poles of the piezoelectric chip, the piezoelectric chip will deform in the thickness direction (i.e. the axial direction of the transducer) due to the converse piezoelectric effect of the piezoelectric ceramic material. The deformation will stretch and compress repeatedly under the action of the alternating current to convert electrical energy into mechanical energy. Under the action of alternating current, the vibrator periodically stretches, compresses and deforms at the resonant frequency, which also drives the resonance of the amplitude modulator. In this way, the vibrator and the amplitude modulator become a simple harmonic vibration unit respectively. The vibrator is excited by the electric signal, and then the amplitude modulator is excited, and the two resonate. While outputting the axial amplitude of each resonant element, the radial direction will also periodically deform. The axial deformation at both ends of the element is the largest, and the radial deformation is the smallest, while the middle node is in the opposite position. The structural gain of the resonant element is proportional to the mass ratio at both ends of the node. The amplitude generated by the ultrasonic transducer depends on the structural gain of the vibrator and the amplitude modulator, as well as the applied voltage. The output amplitude affects the output power of the Ultrasonic Transducer. The greater the amplitude, the higher the voltage, and the higher the output power.
