Metal Stranded Wire Welding by 20Khz 4000w Ultrasonic Metal Welding Machine


Principle:

Ultrasonic copper terminal welding machine uses ultrasonic metal welding principle to weld wires, copper wire, cable, copper strand, copper wire, copper weaving wire (copper wire), copper terminal and copper end piece. In the car occupation and electronic motor occupation, it is possible to weld wires of different sizes to the terminal blocks, so that the welding of the wires in the car wire and the electronic profession reaches the best effect. Detailed performance in copper wire and copper plate welding, motor terminal welding, copper wire and terminal soldering, enameled wire and terminal soldering, copper and terminal soldering, copper and copper end piece soldering, car wire harness soldering, car terminal soldering, copper crimping Terminal soldering and contact switch soldering, used in detail in electronic components of electrical appliances and cars, electronic connectors on steering wheels, wiper switch components, car airbags, etc.

Comparative analysis of ultrasonic welding process of terminal block and traditional crimping:

At present, most domestic enterprises usually use the crimping process in the processing of terminal and wire harness welding. The quality of the processed products is also relatively common, and it is difficult to apply to some high-end high-standard products.

There are several reasons.

1. The tensile test is not closed. Loose, broken, and cracked phenomena occur during actual use. When Tesla tested the charging piles in Nanjing, it was because the welding strength of the terminals was short and the explosion occurred.
2, poor electrical conductivity, high resistivity.

So if the company wants to produce some high-end terminal products, what welding process should it use? Today, I will talk about the ultrasonic welding process with everyone.

The principle of ultrasonic welding is very simple, that is, the generator emits high-frequency electric energy, and the electric energy is converted into mechanical vibration by the transducer, and after being adjusted to the resonance frequency by the horn, it is transmitted to the contact surface of the welding workpiece through the ultrasonic special welding head.

When the high-frequency vibration occurs at the two metal contact faces, the temperature rises instantaneously, the metal surface is fused, and the metal molecular structure is mutually fused; under the pressure of the external force. The two metals are tightly joined together.

This soldering process occurs very quickly, usually in about 1 second, without the need to add flux, solder, shielding gas, etc. The surface of the weld metal does not need to be treated in advance, and all oxides and contaminants are removed in high frequency vibration.

There is no spark in this process, residue splashing and soot, it can be said that it is the most environmentally safe and safe welding technology.
