35kHz Ultrasonic Power Supply Digital Ultrasonic Generator For Rivet Welding

Digital Generator Ultrasonic Power Supply 35kHz 1000Watt for Rivet Welding

Description:

The ultrasonic generator, also called ultrasonic driving power supply, electronic box, control box, is an important part of high power ultrasonic system. Main function is to generate high power and high frequency alternating current, drive the ultrasonic transducer. High-power ultrasonic power supply from the conversion efficiency into consideration generally take the form of switch power supply circuit.Ultrasonic power supply can be divided into self-excited and it excited type power supply, it power called ultrasonic generator excitation type, autonomous power called ultrasonic controller.

Ultrasonic Welding Principle:

When ultrasonic effects on the contact area of thermoplastic plastic, it will produce tens of thousands times per second high-frequency vibration. This the high-frequency vibration achieves a certain amplitude, and passes the ultrasonic energy to the welding area through the welding pieces. Because of the large resistance at the interface of the two welding area, it will produce local high temperature. And also because of poor thermal conductivity of plastic, can not be distributed in time, gathered in the welding area, resulting in two plastic contact surface rapid melting, coupled with a certain pressure, to integrate into one. When the ultrasonic stops, let the pressure last for a few seconds to make it solidified, thus forming a solid molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of raw materials. The quality of ultrasonic plastic welding depends on the amplitude of the transducer and the horn, the welding pressure and the welding time. The welding time and welding horn pressure can be adjusted. The amplitude depends on transducer and booster. The three factors of interaction have a suitable value, if the energy exceeds the appropriate value, the plastic melting amount will be large, easy to deformation of welding; if the energy is small, it is not easy to solder, the pressure can not be too much. This optimum pressure is the product of the length of the welded part and the edge of the optimum pressure per 1mm.
