28KHz Ultrasonic Oscillator System With Transducer and Booster Applied for Spot Welding Machinary

The ultrasonic transducer is the core component of the welding machine, which is mainly composed of a vibrator and an amplitude modulator. Its function is to transform electrical energy into mechanical energy through the simple harmonic vibration of the vibrator itself and driving the resonance of the entire transducer under the excitation of electrical signals. The transducer oscillator adopts a sandwich structure, consisting of pre-stressed bolts that clamp the front and rear drive blocks, piezoelectric chips, and electrode plates. The front drive block and amplitude modulator are assembled through connecting screws.
