High Frequency 40Khz Vibration Ultrasonic Rubber Cutting Blade with Digital Generator

Principle:

The principle of an ultrasonic rubber cutter is to convert a 50/60 Hz current into 20, 30 or 40 kHz of electrical energy by means of an ultrasonic generator. The converted high-frequency electrical energy is again converted by the transducer into mechanical vibration of the same frequency, and then the mechanical vibration is transmitted to the cutting blade through a set of amplitude modulator devices that can change the amplitude. The ultrasonic rubber cutting blade vibrates along its length with an amplitude of 10-70 μm and repeats 40,000 times per second (40 kHz) (the vibration of the blade is microscopic and generally difficult to see by the naked eye). The cutting blade then transmits the received vibration energy to the cutting surface of the workpiece to be cut, in which the vibration energy is cut by activating the molecular energy of the rubber molecule and opening the molecular chain.

Structural composition:

The main components of an ultrasonic cutting system include an ultrasonic generator (drive power), an ultrasonic transducer, a horn, a cutter (tool head), and various output lines and control lines. The ultrasonic drive power source converts the commercial power into a high-frequency high-voltage alternating current and outputs it to the ultrasonic transducer. An ultrasonic transducer is actually equivalent to an energy conversion device that converts input electrical energy into mechanical energy, ie, ultrasonic waves. Its manifestation is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic motion is equivalent to the frequency of the high frequency alternating current supplied by the driving power source. The role of the horn is to fix the entire ultrasonic vibration system and to amplify the output amplitude of the transducer. The cutting blade (tool head) further enlarges the amplitude on the one hand and focuses the ultrasonic wave. On the other hand, the ultrasonic wave is output, and the ultrasonic energy is concentratedly input to the cutting portion of the material to be cut by using a similar cutting edge of the cutting blade. Under the action of huge ultrasonic energy, the part softens and melts instantaneously, and the strength is greatly reduced. At this time, as long as a small cutting force is applied, the purpose of cutting the material can be achieved.
