What is an ultrasonic welding horn?
Ultrasonic horn is a general term for all ultrasonic transmitters, and it is an indispensable part of ultrasonic welding equipment. Its function is to couple the ultrasonic waves generated by the transducer to the processed object. Because it must transmit ultrasonic waves, the welding head must work in resonance, that is, its natural resonance frequency must match the transducer. Secondly, the amplitude must be uniform, and the shape of the end face of the welding horn must be adapted to the shape of the workpiece to be welded.
The service life of the welding horn is critically determined by two aspects: First, the material, and the second. The material is one of the main reasons to ensure the life of the ultrasonic horn and the effect of the welding product. The process of completing the horn is complicated.
Ultrasonic welding horn material
1. Aluminum-magnesium alloy horn are used in the manufacture of vibration systems (horns) and welding horn. This material has extremely high mechanical yield strength, high hardness, and strong thermal conductivity. It is an ideal ultrasonic horn manufacturing material; but aluminum It is not wear-resistant, suitable for general welding requirements
2. Titanium alloy horn: The model used for continuous vibration. It has higher bremsstrahlung, good heat conduction, higher hardness, higher cost than magnesium-aluminum alloy, but more durable and wear-resistant than magnesium-aluminum alloy molds.
3. Imported hard alloy steel horn: imported alloy material with extremely high hardness, used for continuous welding or welding requiring ultra-high wear resistance, low thermal conductivity, high mechanical loss of ultrasonic waves, because of wear resistance, low cost of use, but The production process is more complicated
Ultrasonic welding horn process
Many customers think that the design and production of ultrasonic welding horn is very simple, which is misleading. When using an improperly processed or untuned ultrasonic welding horn, it will bring expensive losses to your production-it will destroy the ultrasonic welding effect, and even more serious will directly cause the ultrasonic transducer or ultrasonic generator damage.
