3200W 20khz Digital Ultrasonic Welding Generator For Automobile Parts Machine

The ultrasonic power generator for metal welding has the advantages of simple operation, fast welding speed, high welding strength and high production efficiency, which is very suitable for the needs of modern large-scale production. As a key part of ultrasonic welding, metal welding ultrasonic power generator still has problems in current domestic products, such as poor frequency automatic tracking performance, output amplitude stability and continuous adjustability, which are difficult to meet practical requirements.

 

 

 

The ultrasonic power generator for metal welding specifically discloses a high-frequency inverter circuit, a high-frequency transformer, at least one ultrasonic transducer, a microprocessor, a voltage-controlled oscillator, and an automatic frequency tracking circuit. The high-frequency inverter circuit, high-frequency transformer and ultrasonic transducer are connected in turn, and the microprocessor generates frequency signals to control the operation of the ultrasonic transducer. The power regulation is realized by microprocessor phase shifting, Frequency tracking is realized by controlling the voltage controlled oscillator with the deviation of the effective value of the current in a period.

 

 

 

The ultrasonic power generator for metal welding provides a power supply system for ultrasonic welding machines with simple and reasonable structure, strong automatic frequency tracking performance, stable output amplitude and high continuous adjustability, so as to overcome the shortcomings of the existing technology.
