How much do you know about the most advanced welding process
With the rapid development of science and technology, the manufacturing process is also constantly innovating. Today I will introduce the ultrasonic plastic welding machine, which we generally call the ultrasonic plastic welding machine. The ultrasonic plastic welding machine is easier to operate than traditional welding. The welding time is shorter and the welding strength is greater. So why do ultrasonic plastic welding opportunities have so many advantages? I believe that everyone understands the principles of ultrasonic plastic welding machine.
1. How does high temperature occur?
When we are doing plastic welding, we need higher temperatures. In traditional welding, high levels are generated by gas combustion, such as acetylene. For ultrasonic plastic welding machines, the source of high temperature is the high-frequency vibration generated by ultrasonic waves. This high-frequency vibration transmits ultrasonic energy to the workpiece contact surface through the weldment. As the contact surfaces vibrate and rub against each other, high temperatures are generated.
2. How is plastic welded?
When high temperature is generated by high-frequency vibration friction, due to the poor thermal conductivity of plastic parts, instant heat cannot be dissipated quickly, so that it accumulates on the contact surface of the workpiece, causing the two plastic contact surfaces to melt rapidly, and then an external force is applied by the welding abrasive to make The plastic pieces are well welded. After curing, the pressure is removed, so that the two plastic parts are perfectly fused, and the welding strength is very strong, close to the body.
3. Several factors affecting the welding effect
The welding effect of the ultrasonic plastic welding machine is mainly caused by the following three factors: (1) the amplitude of the transducer, the transducer can control the amplitude of the ultrasonic vibration to achieve the purpose of controlling the temperature; (2) the welding time . The welding time guarantees the welding effect of the two plastic parts, and the stability after welding; (3) the external force. The effect of external force is to ensure that the welding effect of plastic parts is better, and the external force cannot be too large, otherwise the plastic parts will be easily deformed.
4.The structure of ultrasonic plastic welding machine
The ultrasonic plastic welding machine is composed of a pneumatic transmission system, a control system, an ultrasonic generator, a transducer, a horn and a welding head, and a tooling fixture. The system can realize intelligent control, so the welding effect is controlled by digital imaging technology to operate the welding time and pressure time to fully guarantee the final welding effect.
5.Safety of ultrasonic plastic welding machine
In addition to the superior welding performance of ultrasonic plastic welding machine, the welding process is safe, environmentally friendly and pollution-free, which is another important feature. Traditional ordinary welding temperature is not easy to control, and it is easy to cause danger during the welding operation. In addition, the light generated during welding is also easy to cause damage to the eyes. Difficult to control.
Ultrasonic plastic welding technology has taken the welding industry to a new level. Ultrasonic welding is more widely used, allowing different plastics to achieve better integration, and also makes plastic products more widely used in our lives. With the continuous progress of ultrasonic plastic welding machine, it will bring more and more convenience to our lives.
