What is a Rubber Cutting Machine?
The rubber ultrasonic cutting machine uses the energy of ultrasonic waves to heat and melt the material to be cut locally, to achieve the process of cutting the material.
The Principle of Rubber Cutting Machine:
Rubber ultrasonic cutting machine is a type of equipment that uses ultrasonic energy for cutting. Rubber ultrasonic cutting machine is a special application of the ultrasonic cutting machine. It is a type of equipment that uses ultrasonic energy for cutting and processing. Its biggest feature is that cutting does not require cutting edges.
Rubber is a highly elastic polymer, which has the characteristics of high elasticity, strong toughness, and stickiness at high temperatures, so it is difficult to process by traditional mechanical cutting. Ultrasonic cutting avoids the shortcomings of traditional mechanical cutting to a certain extent and can cut rubber in various angles and directions, and the rubber is still smooth and smooth after cutting.
The principle of the ultrasonic rubber cutter 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 into mechanical vibration of the same frequency again through the transducer, and then the mechanical vibration is transmitted to the cutting knife through a set of amplitude modulator devices that can change the amplitude. The ultrasonic rubber cutter vibrates along its length with an amplitude of 10-70 μm, repeated 40,000 times per second (40 kHz). The cutting knife transmits the vibration energy received to the cutting surface of the workpiece to be cut, and in this area, the vibration energy is used to cut the rubber material by activating the molecular energy of the rubber and opening the molecular chain.
Traditional cutting is to use 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 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, the cutting edge of the cutting tool should be sharp, and the material itself must bear relatively large pressure. The cutting efficiency of soft, elastic materials is not high.
The rubber ultrasonic cutting machine is completely different. It uses the energy of ultrasonic waves to heat and melt the material to be cut locally, 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 it will not cause chipping and damage to the material to be cut. At the same time, due to the ultrasonic vibration of the cutting blade, the frictional resistance is 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, objects that are inconvenient to pressurize, etc. Another great advantage of ultrasonic cutting is that it has a fusion effect on the cutting part while cutting, and seals the edge of the cutting part without causing flashing of textile materials. Ultrasonic cutter type cutting machine directly loads ultrasonic energy onto the cutter, and the cutter becomes a cutter with ultrasonic waves. When cutting materials, the materials are mainly softened and melted by ultrasonic energy, and the cutting edge of the cutter only plays the role of kerf positioning, ultrasonic energy output, and separation of materials. This cutting method is suitable for cutting thick, thick, long, and other materials that are inconvenient to set on a cutting board. Such as raw rubber cutting, pipe cutting, frozen meat, candy, chocolate cutting, cake cutting, printed circuit boards, etc.
Structural composition of rubber cutting machine:
The main components of a set of ultrasonic cutting systems include an ultrasonic generator (driving power), ultrasonic transducer, horn, cutting knife, and various output lines and control lines. The ultrasonic driving power supply converts the mains power into high-frequency high-voltage alternating current and outputs it to the ultrasonic transducer. The ultrasonic transducer is equivalent to an energy conversion device, which can convert the input electrical energy into mechanical energy, that is, ultrasonic waves. Its manifestation is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic motion is equal to the frequency of the high-frequency alternating current supplied by the driving power supply. The function of the horn is to fix the entire ultrasonic vibration system on the one hand and amplify the output amplitude of the transducer on the other hand. The cutter further amplifies the amplitude and focuses the ultrasonic waves. On the other hand, it outputs ultrasonic waves, using 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 is instantly softened and melted, 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.
