Structural characteristics of ultrasonic wire harness welding machine
1. The machine consists of a chassis, guide pillars, transducers, pneumatic systems, PC circuits, and bottom molds.
2. The sound component consists of two parts: a transducer and a welding head. The transducer uses a piezoelectric oscillator, which converts electrical energy into mechanical vibration. A transformer is analogous to a transformer in a circuit, playing a role in mechanical damping transformation and amplitude amplification. The welding head is designed according to the welding requirements and the shape of the workpiece, and it also plays a role in secondary impedance transformation and amplitude amplification. From the perspective of structure and shape, the welding head is not complicated, but it requires the best design, materials, and processing techniques. Welding heads with complex shapes and large sizes are difficult to design and are generally designed by manufacturing plants.
3. The air pressure system is powered by compressed air and switches circuits through solenoid valves, pushing the cylinder piston to drive the welding head to move up and down. Use a pressure regulating valve to control the pressure, and use a one-way throttle valve to control the lifting speed.
4. The control circuit performs program control on the welding process. The function keys on the panel can be used to set the welding time and delay time according to different objects being welded. Then, by pressing the foot switch, the welding machine will automatically complete one welding process.
5. The ultrasonic power generator provides electrical power to the sound component. Due to significant changes in the resonant frequency and impedance of the acoustic components during the welding process, the ultrasonic power generator must have the ability to automatically track the frequency and adjust the output power according to the load. Jiayuanda ultrasonic metal spot welding machine adopts external oscillation; Automatic frequency tracking using phase method; Constant vibration speed control.

FAQ
Q: What about the service life of Ultrasonic Wire Harness Welding's welding horn?
The service life of a welding head depends on two aspects: material and process
In terms of materials: ultrasonic welding requires that metal materials have the characteristics of good compliance (small mechanical loss in the process of sound wave transmission), so the most commonly used materials are aluminum alloy and titanium alloy. However, ultrasonic metal welding requires that the welding head wear resistance (requires high hardness), which makes the selection of materials more difficult. Because hardness and toughness seem to be naturally opposed, it requires us to select materials with very high requirements, The high-quality steel materials we choose can better solve this contradiction and maximize the effective life of the welding head.
Process: including the processing process and subsequent treatment process. The processing process has been described in detail above. The subsequent treatment includes heat treatment and parameter trimming. Based on the materials selected by our company, we have an original heat treatment process to ensure; After each welding head is made, the parameters shall be measured and adjusted separately to ensure the product.
