28KHZ arba 35KHZ arba 40KHZ rankinis ultragarsinis pjovimo peilis / Pjovimo mašina gumos pjaustymui

The principle of ultrasonic rubber cutting knives is to convert 50/60Hz current into 20, 30, or 40kHz electrical energy through an ultrasonic generator. The converted high-frequency electrical energy is converted again into mechanical vibration of the same frequency through a transducer, and then the mechanical vibration is transmitted to the cutting knife through a set of amplitude modulation devices that can change the amplitude. Ultrasonic rubber cutting knife along its length direction at a rate of 10-70 μ The amplitude of m is repeated 40000 times per second (40 kHz) to vibrate (the vibration of the blade is microscopic and generally difficult to see with the naked eye). The cutting knife then transmits the received vibration energy to the cutting surface of the workpiece to be cut. In this area, the vibration energy is activated by rubber molecular energy, opening the molecular chain to cut the rubber material.
