The ultrasonic guardrail tube welding machine is a semi-automatic controlled machine. The operator only needs to put the lamp tube into the mechanical fixture and press the start switch. The two clamping cylinders will descend to position the workpiece in the ultrasonic mold . Then the ultrasonic fixture will trigger ultrasonic waves, and the welding head will weld the workpiece. After the welding is completed, the cylinder drives the upper mold to reset, and the clamping cylinder rises. At the same time, the workpiece is cooled and shaped under a certain pressure. Perfect welding is achieved in one go. The operator takes out the workpiece to complete the welding process.
Ultrasonic guardrail tube welding machine is also known as LED guardrail lamp tube welding machine, plastic tube sealing machine, LED guardrail tube welding machine, LED bridge lamp welding machine, guardrail lamp tube welding equipment, guardrail tube two-end sealing welding machine, LED outline light welding machine, LED digital code tube welding machine, LED guardrail screen welding machine, plastic tube welding machine.
Ultrasonic welding principle of LED guardrail lamp ultrasonic welding machine :
First, the ultrasonic control box generates a 15KHZ frequency, a high-frequency electrical signal, which is converted into a mechanical oscillation of the same frequency through the effect of the transducer. The ultrasonic guardrail tube welding machine is used on plastic workpieces in the form of audio longitudinal waves. The temperature transmitted to the interface is increased through the friction between the surface and internal molecules of the workpiece. When the temperature reaches the melting point of the workpiece itself, the workpiece interface quickly melts and fills the gap at the interface. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, and the work is completed in one go to achieve perfect welding.
