The Working Principle and Construction of Ultrasonic Cutting Machine
The Working Principle and Construction of Ultrasonic Cutting Machine
Working Principle:
The principle of ultrasonic cutting
machine is totally different from that of traditional cutting. It use the
energy of ultrasonic waves to heat and melt the parts of the cut material, so
as to achieve the purpose of cutting the material. Therefore, Ultrasonic
cutting does not require sharp cutting edge, nor does it require great
pressure, which will not cause the edge breakage and damage of the cutting
material. At the same time, because the cutting tool is doing ultrasonic
vibration, the friction resistance is very small, the cut material is not easy
to stick to the blade. This is especially effective for cutting the viscous and
elastic materials , froze materials, such as food, rubber etc., or objects that
are difficult to apply pressure.
Basic structure of
ultrasonic cutting machine:
Ultrasonic transducer: It is essentially an energy conversion device that converts incoming electrical
energy into mechanical energy or ultrasound. It is represented by a transducer
stretching back and forth vertically. The frequency of the telescopic motion is
the same as the frequency of the high frequency AC current supplied by the generator.
Booster: The function of the booster is to fix the whole ultrasonic vibration system and
enlarge the output amplitude of the transducer.
Cutter: The
cutter on the one hand further amplifies the amplitude and focuses
on the ultrasonic wave. On the other hand, output the ultrasonic wave, and the
ultrasonic energy is concentrated into the cutting part of the cut material by
using the similar cutting edge of the cutting knife. Under the action of huge
ultrasonic energy, this part immediately softens, melts, the strength drops greatly.
At this point, as long as a small cutting force is applied, the purpose of
cutting materials can be achieved.
Generator: Converts the power supply into high frequency and high voltage AC current and
transmits it to the ultrasonic transducer.
