what kind of ultrasonic system composed by ultrasound welding machine

(1) Transducer The acoustic system used in ultrasonic plastic welding machine includes three parts: 

1 driving part 

2 fixed part 

3 working part. 

In the above three parts, the driver is the core, generally adopts bolt clamping longitudinal vibration transducer, the half wave vertical oscillator with a quarter of the wavelength of longitudinal vibrator, half the wavelength of longitudinal vibration and the half wave shaped device connected to form a full wavelength plastic welding transducer, and the quarter wave vertical oscillator with quarter wave shaped device is linked together, Form a half-wavelength transducer. 

(2) The tool head needs different tool heads for different welding objects, whether it is near field welding or transmission welding, only the tool head with half wavelength can achieve the maximum amplitude of the welding end face. There are two kinds of tool head with amplitude amplification and without amplitude amplification. The acoustic system tool head for plastic welding machine is usually made of aluminum alloy, and its end face is plated with hard alloy. When the power is large, it is also made of titanium alloy, and the fatigue strength of this material is more than twice that of aluminum alloy. Ultrasonic plastic welding machine due to the use of different occasions and welding materials, welding size is not the same, its specifications are all kinds of. Its output power ranges from tens of watts of manual welders to a few kilowatts of mainframes, with frequencies generally in the 15KHz to 40KHz range
