Working principle of equipment:
The transducer transforms the high-power oscillation signal of supersonic frequency into mechanical energy of corresponding frequency and applies it to the interface of the metal sheet that needs to be fused, so that the metal sheet is heated instantly, and then the particles in the metal lattice are started, so that the molecules in the metal sheet are fused together through mutual penetration.
Equipment components:
The metal welding machine is mainly composed of ultrasonic generator, transducer, mold, pneumatic parts, frame and so on.
Equipment Functional features:
1. Intelligent digital circuit, advanced CPU central processing system.
2. With energy mode, power mode, time mode multiple intelligent control modes.
3. Ultrasonic frequency automatic tracking.
4. Energy, time, power, a variety of upper and lower limit quality alarm function.
5. DO signal ：welding machine alarm,Ready, IO signal output during ultrasonic sending.
6. DI signal：EMERGENCY STOP, Start wedding.
7. 485 communication protocol, Data receiving and uploading.
8. The ultrasonic equipment is actively controlled（with 24V auxiliary power supply）
