Customized 20khz 3000w Ultrasonic Copper Metal Welding Horn for Pre-crimped Wire

Description:

Ultrasonic wire harness welding is mainly used for welding all kinds of precision metal components. Compared with traditional soldering, electric resistance welding and other industries, it is safer and more environmentally friendly. The welding quality of the products is higher, the conductivity is stronger, and the resistivity is lower. Solder, flux and shielding gas are not required during the soldering process. No sparks, no high light, no high temperatures. Very green. For the welding of coated metals, it is not necessary to treat the surface oxides and contaminants in advance, and the welding operation can be directly performed.

The ultrasonic wire harness welding machine is mainly composed of an ultrasonic generator, a transducer, a welding head and a pneumatic part. It is suitable for the connection of transistors, integrated circuits and electrolytic capacitor components. The system is easy to install, install and operate. The system can adjust the sequence to complete the wire harness welding of 0.5 to 25mm2 cross-sectional area. It is a process between cold press welding and friction welding that utilizes high-density energy generated by high-frequency mechanical vibration. The mechanical vibration of the welding head of ultrasonic metal welding is parallel to the surface of the workpiece. In the case of pressurization, the surfaces of the two metal strands are rubbed against each other to form a fusion between the molecular layers, and finally a square-like fusion is formed.

What is the effect of ultrasonic terminal welding?

Tensile test: The 0.85 square wire was repeatedly tested at a tensile force of 130 N, and the ultrasonic welding and the terminal crimping were not pulled off.

Resistance test: 0.85 square meters, length 600mm wire, under the test of digital DC bridge, the average value of ultrasonic welding is 10.30mΩ, and the average value of terminal crimping is 11.62mΩ. It can be seen from the test results that the resistance of the ultrasonic welding is 1.32 mΩ lower than that of the terminal crimping, thereby improving the electrical conductivity of the wire harness and the new energy of signal transmission.

Therefore, some high-profile wire harness terminal products are currently welded by ultrasonic waves. These products are also commonly used in automotive wiring harnesses, new energy vehicles, electric vehicles, charging piles, and some high-voltage cables.

The welding process is constantly innovating. How to establish its own product reputation in the enterprise and stand out from many products? Process upgrades are indispensable.
