Le principe de fonctionnement et les avantages de coupe du coupe-caoutchouc à ultrasons

Le caoutchouc est un polymère hautement élastique, qui présente les caractéristiques d'une grande élasticité, d'une forte ténacité et d'une adhérence à haute température, il est donc difficile à traiter par découpe mécanique traditionnelle. La découpe du caoutchouc par ultrasons évite dans une certaine mesure les défauts de la découpe mécanique traditionnelle et peut couper le caoutchouc dans différents angles et directions, et le caoutchouc est toujours lisse et lisse après la coupe.

Il existe deux principaux types de méthodes traditionnelles de découpe du caoutchouc : le travail à chaud et le travail à froid. En ce qui concerne les matériaux en caoutchouc, il est plus adapté à la découpe à froid. La coupe à froid présente les avantages de moins de génération de chaleur, moins de déformation thermique, moins de poussière générée pendant la coupe, et la section ne vieillira pas et ne se fissurera pas en raison d'une température excessive. La coupe du fil dans le travail à froid a une plus grande précision, mais la vitesse est très lente. Parfois, il est nécessaire d'utiliser d'autres méthodes pour une perforation supplémentaire et un enfilage de fil à couper, et la taille de coupe est fortement limitée. La découpe du caoutchouc par ultrasons consiste à utiliser une découpe à froid pour éviter la déformation du caoutchouc due au chauffage.

Comment fonctionne la découpe de caoutchouc par ultrasons :

The ultrasonic rubber cutting knife uses ultrasonic energy to locally heat the cutting part to melt it, thereby cutting. The whole cutting process will not cause chipping and damage of the cutting material. Ultrasonic cutting uses high-frequency vibration to cut rubber, rather than simply cutting with blade pressure, which reduces friction with rubber, so the blade is not easy to stick.

Problems with traditional cutting:

Rubber is the raw material of parts commonly used in the industry at present, and it has a wide range of applications, and many rubber parts are formed by cutting rubber sheets. Traditional rubber cutting uses mechanical cutting methods. The more common ones are grinding wheel cutting, but most of them are cut. After the rubber has been cut in a similar way, there will be several cracks on the cutting surface, and improper cutting can easily cause the bending of the cutting line. In addition, rubber tangents often have wavy bends, which are formed by heat during the cutting process. These cutting problems will affect the aesthetics of the entire rubber product.

Traditional rubber cutting method:

Disc knife cutting rubber is a relatively common way of cutting rubber. Although the price is relatively cheap, there are several problems in actual cutting.

In the process of cutting rubber materials, the disc knife is prone to instability, that is, the cutting situation cannot meet the process requirements, the width of the cutting surface is not enough, the edges are curled, and the cutting surface is uneven.

The cutting angle of the disc knife is easy to change, and it is difficult to adjust the cutting angle.

The blade of the disc knife is sharp and the rotation speed is relatively fast, which is not safe during the cutting process and is easy to hurt people.

Advantages of ultrasonic cutting:

1. High precision cutting

The ultrasonic vibration reduces the frictional resistance between the blade and the material, so that the blade can cut smoothly without deformation. Ultrasonic vibration reduces material sticking on the blade, thereby reducing downtime in cleaner production systems. Throughout the cutting process, the blade surface remains smooth, clear and clean.

2. Sustainable cutting

Ultrasonic blade output is monitored in real time through a closed loop circuit to ensure continuous rubber cutting.

3. Dry - no lubrication required

Because the ultrasonic cutting blade passes smoothly through the rubber and the ultrasonic vibration vibrates at 20,000 to 40,000 cycles per second, there is no need to lubricate the blade throughout the process.

4. Avoid material flash

When the rubber is cut, it has a fusion effect on the cutting part, and the cutting part is completely sealed without causing flash of the rubber material.

5. Applicable to various working environments

Ultrasonic cutting equipment can be air-cooled and water-cooled to suit various working conditions and environments.

6. Easy to integrate into automation

Ultrasonic rubber cutting knives are small in size. In addition to hand-held operation, they can also be installed on automated integrated machines for use, which is easier to operate and has higher cutting accuracy.
