Description
Traditional cutting uses a knife with a sharp edge to press against
the material to be cut. This pressure is concentrated at the
cutting edge, and the pressure is very large, exceeding the shear
strength of the material to be cut, and the molecular bonds of the
material are pulled apart and cut. Since the material is pulled
apart by strong pressure and rigidity, the cutting edge of the
cutting tool should be very sharp, and the material itself has to
withstand relatively large pressure. For soft and elastic
materials, the cutting efficiency is not high.
The rubber ultrasonic cutting machine is completely different. It
uses ultrasonic energy to heat and melt a part of the material to
be cut, so as to achieve the purpose of cutting the material.
Therefore, ultrasonic cutting does not require a sharp edge, nor
does it require a lot of pressure, and will not cause chipping or
breakage of the material to be cut. At the same time, because the
cutting knife is vibrating ultrasonically, the frictional
resistance is particularly small, and the material to be cut is not
easy to stick to the blade. This is especially effective for
viscous and elastic materials, frozen materials, such as food,
rubber materials, and objects that are inconvenient to apply
pressure. Ultrasonic cutting has another great advantage, that is,
it has fusion effect on the cutting part while cutting, sealing the
cutting part, and will not cause the flash of the textile material.
The ultrasonic cutter type cutting machine directly loads the
ultrasonic energy on the cutter, and the cutter becomes a cutter
with ultrasonic. When cutting the material, the material is mainly
softened and melted by ultrasonic energy, and the cutting edge of
the cutter only plays the role of cutting seam positioning,
ultrasonic energy output, and separating the material. This cutting
method is suitable for cutting thick, thick, and long materials
that are inconvenient to set up the cutting board. Such as the raw
rubber output from the mixing machine, pipe cutting, frozen meat,
candy, chocolate cutting, cake cutting, printed circuit boards,
etc.
Working principle
The principle of ultrasonic cutting is to convert 50/60Hz current
into 20, 30 or 40KHz electric energy through an ultrasonic
generator. It is converted into mechanical vibration of the same
frequency, and then the mechanical vibration is transmitted to the
cutting knife through a set of amplitude modulator device that can
change the amplitude. The cutting knife transfers the received
vibration energy to the cutting surface of the workpiece to be cut.
In this area, the vibration energy is used to cut the rubber by
activating the molecular energy of the rubber and opening the
molecular chain.
Structural composition characteristicsedit
The main components of an ultrasonic cutting system include
ultrasonic generator (driving power supply), ultrasonic transducer,
horn, cutting knife (tool head) and various output circuits and
control circuits. The ultrasonic drive power converts the mains
electricity into high frequency and high voltage alternating
current, which is output to the ultrasonic transducer. The
ultrasonic transducer is actually equivalent to an energy
conversion device, which can convert the input electrical energy
into mechanical energy, that is, ultrasound. Its manifestation is
that the transducer stretches back and forth in the longitudinal
direction. The frequency of the telescopic movement is equal to the
frequency of the high-frequency alternating current supplied by the
driving power supply. The role of the horn is to fix the entire
ultrasonic vibration system, and the other is to amplify the output
amplitude of the transducer. On the one hand, the cutting knife
(tool head) further amplifies the amplitude and focuses the
ultrasound. On the other hand, it outputs ultrasonic waves, and
uses the similar cutting edge of the cutting knife to concentrate
the ultrasonic energy into the cutting part of the material to be
cut. Under the action of huge ultrasonic energy, this part
instantly softens and melts, and its 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.
