Metals welding ultrasonic generator 20khz/40khz/2000W

Ultrasonic metal welding machine generator is used to convert power frequency (50 Hz) current into ultrasonic frequency (15 ~ 60 kHz) oscillation current and match with ultrasonic transducer through output transformer. At present, there are many kinds of circuit forms, such as electron tube amplifier, transistor amplifier, thyristor inverter and transistor inverter. Among them, the efficiency of electronic tube type is only 30% - 45%, which has been replaced by transistor amplifier. At present, transistor amplification generator is widely used. When ultrasonic generator is used as welding application, automatic frequency tracking is a necessary performance. Due to the change of load and natural frequency of acoustic system in welding process, in order to ensure the stability of welding quality, the feedback signal from load is used to form the self-excited state of the generator to ensure automatic tracking and super optimal load matching.

 

In the future, transistor amplification generator will also be widely used. The traditional ultrasonic metal welding machine generator will be replaced by it. The automatic frequency generation electric box has been formally diffused into the hands of the user manufacturers, making the metal welding machine operation easier, faster and more convenient. Ultrasonic manufacturers are also constantly updated, hope to use ultrasonic factory in the selection of power transistor amplifier type ultrasonic generator welding machine.
