Welding Multi or Single Wire into Wire Knot by 20Khz Ultrasonic Technology​


Description:

Ultrasonic automotive wire harness welding uses ultrasonic metal welding technology to weld metal wire harnesses, and converts high-frequency electrical energy into a mechanical vibration energy through a transducer to act on the metal wire harness. When the temperature of vibration friction heat reaches the melting point of the wire metal, the wire harness It will melt, and the wire harness will apply a certain pressure while the wire bundle is being fused. Finally, the wire harness welding device moves away and stops the mechanical vibration, which will form a wire harness welding effect. During the wire harness welding process, no current is passed through the weldment, and no welding arc is generated. Because ultrasonic welding does not have problems such as heat conduction and electrical resistivity, it is undoubtedly a kind of welding for non-ferrous metal wire harnesses. In an ideal metal wire harness welding system, the wire harness welding effect is generally square.

Parameters:

The principle of ultrasonic metal welding is to transmit high-frequency vibration waves to two metal surfaces to be welded. Under pressure, the two metal surfaces rub against each other to form a fusion between molecular layers, which has the advantages of being fast and energy-saving. High fusion strength, good electrical conductivity, no sparks.

Vibration system test:

In order to achieve the best working condition and maintain the performance of the ultrasonic metal welding machine to ensure the normal operation of the vibration system, the vibration system must be inspected.

1. The components of the rack must be tightened, and the welding head should not touch the work or fixture.

2. Turn on the power, then the power indicator lights up.

3. Press the overload test button to see if the resonant frequency of the vibration system is within the working range, and whether there is an overload condition.

4. In general, the sound of ultrasonic waves is a relatively smooth and soft sound. If there is a strange sound, please use it after inspection.

5. No abnormal sound, you can work normally. For the entire ultrasonic metal welding machine, the welding head is a consumable part, which has a service life limit. The service life of the welding tool head is affected by various factors, the main factors being the hardness difference between the tool head (hardened tool steel) and the workpiece (eg non-ferrous metal) and various parameters of the welding. Long-term welding can cause wear or even breakage of the weld head, and when the weld head has a problem, the weld head must be replaced.
