Ultrasonic transducer is a kind of energy conversion device. Its function is to convert the input electrical power into mechanical power (ultrasound) and then transmit it, and it consumes a small part of the power (less than 10%). Therefore, the main consideration when using an ultrasonic transducer is the matching with the input and output ends, followed by mechanical installation and matching dimensions.
Classification of ultrasonic transducers:
1. Column type
2. Inverted horn type
3. Steel back cover type
4. Intermediate aluminum sheet type
Mainly suitable for ultrasonic plastic welding machine, ultrasonic cutting knife, ultrasonic metal welding machine, ultrasonic cleaning machine, ultrasonic sonochemical equipment, etc.
Ultrasonic transducers can vibrate regularly under appropriate electric field excitation, and their amplitude is generally about 10μm. Such amplitude is not enough to directly complete the welding and processing procedures. After connecting to a reasonably designed horn, the amplitude of the ultrasonic wave can be changed in a large range, as long as the material strength is sufficient, the amplitude can exceed 100μm.
Due to different processing methods and requirements, the working mode of the transducer can be roughly divided into continuous work (such as lace machine, CD machine, cleaning machine, zipper machine) and pulse work (such as plastic welding machine). The requirements of the device are different. Generally speaking, continuous work has almost no pause time, but the working current is not very large, and the pulse work is intermittent with pauses, but the instantaneous current is very large. On average, the power in the two states is large.
