The oscillator of the 2000W 15KHZ/20KHZ ultrasonic welding transducer in the ultrasonic processing device usually includes the transducer, amplitude converter, and tool head. In practical work, in order to output a larger amplitude of the transducer, it is necessary to increase the amplitude ratio. The usual approach is to reduce the diameter of the output part of the amplitude converter, thereby reducing the structural strength of the amplitude converter. This often leads to structural damage to the amplitude converter due to excessive stress concentration during operation, Frequent replacement of the horn is required, which is costly to use and affects the ultrasonic welding performance.
A 2000W 15KHZ/20KHZ ultrasonic welding transducer vibrator is a transducer that includes a pre tightened bolt, a cover plate, a piezoelectric vibrator, a power cord, a variable amplitude pole, a fixing ring, a screw, and a welding head. The pre tightened bolt passes through the cover plate and is connected to the piezoelectric vibrator. The piezoelectric vibrator is installed between the cover plate and the variable amplitude pole, and the power cord is set on the outer side of the piezoelectric vibrator. The end of the power cord far from the piezoelectric vibrator is equipped with a power interface.
The piezoelectric ceramic plates and electrode plates of the 2000W 15KHZ/20KHZ ultrasonic welding transducer oscillator are alternately stacked with multiple piezoelectric ceramic plates and electrode plates. The pre tightened bolt passes through the cover plate and is then connected to the piezoelectric vibrator. After assembly, due to the pre tightening force applied by the pre tightened bolt, the piezoelectric vibrator can be pressed and pressed tightly with the cover plate, improving the electroacoustic conversion efficiency of the transducer. During operation, the power line is connected to the external power supply through the power interface, and after applying power electrical signals to the piezoelectric vibrator, it causes the piezoelectric vibrator to vibrate, resulting in ultrasonic waves, Implementing a transducer to convert electrical energy into ultrasonic energy, effectively amplifying the amplitude output by the piezoelectric oscillator through a protruding external amplification structure of the gradually expanding part, increasing the amplitude ratio, and effectively solving the problem of reducing the diameter of the output part of the amplitude converter to increase the amplitude ratio, thereby reducing the structural strength of the amplitude converter. The groove is set at the connection between the gradually expanding part and the input part, thereby effectively reducing stress concentration, To avoid structural fracture of the amplitude converter, the amplitude converter can concentrate and enhance the ultrasonic energy generated by the transducer, and transmit it along the screw to the welding head, allowing the welding head to obtain more and more powerful welding energy. This effectively solves the welding problems of insufficient welding energy caused by large welding areas and multiple welding layers, such as weak welding, and improves the stability and reliability of welding work. The utility model has a compact structure and reasonable design, reduces excessive stress concentration, ensures good structural strength, and improves ultrasonic welding performance.
