4、Process performance

  1. The principle of the equipment is that the transducer converts the ultrasonic high-power oscillation signal into the mechanical energy of the corresponding frequency, which is applied to the interface of the metal sheet to be welded, so that the joint of the metal sheet can generate heat instantly, and then the particles in the metal lattice can be started, so that the molecules at the joint of the metal sheet can penetrate each other and be welded together to complete the welding.

2. Adopt advanced constant current and constant voltage circuit technology, and the ultrasonic amplitude is continuously adjustable.

3. Adopt intelligent ICs chassis control system with secondary ultrasonic function; The system has the function of power on self-test, intelligent segmentation of vibration pair, automatic tracking, and signal transmission on the computer.

4. The mechanical structure of the machine head adopts German x guide rail structure, with high precision.

5. It has a voltage protection system (the range of power supply voltage is 220V ~ 250V); The output power and working frequency of the machine will not be affected during the automatic     constant voltage period.

6. It has overload protection system.

7. It has overcurrent protection.

8. It has automatic compensation for unstable power supply frequency.

9. With welding overload protection signal feedback.

10. Computer data monitoring and data uploading.

11. Intelligent ICs system: intelligent chip digital circuit, high-density integrated central processing system, millisecond level sampling control.

12. Intelligent segmentation and automatic tracking of amplitude. 1% - 100% amplitude can be set within 0-1000ms to adapt to different welding processes.

13. The system does not need to be recalibrated after self-test, automatic frequency search, welding head replacement or mold repair.

14. The frequency is automatically tracked during operation. During operation, the frequency of the welding head and the transducer will shift with the change of temperature and load. The welding machine can automatically search and track the resonant frequency of the transducer in the whole range, so as to ensure that the transducer always works in the resonant state, ensure the high-efficiency operation of the equipment, and make the welding more stable and reliable.

15. Match various welding modes such as energy and intelligent time: different welding modes adapt to different welding process requirements to achieve better welding effect.

16. 7-20 welding parameters can be preset in advance to meet different welding process requirements. The operator can directly access the data to weld, which greatly improves the work  efficiency.

17.7 inch high-definition touch screen, intuitive chart operation interface.

18. The welding effect of each time is displayed on the high-definition man-machine exchange touch screen through data, and the welding process is displayed in a curve.

19. Each welding data can be transmitted to the monitoring computer, so that the welding data can be traced and the defective rate can be reduced.

20. Intelligent system security protection and monitoring.

21. The alarm output and reset function can set different alarm values to make the quality control more in place.

22. Multi level password protection can be set to separate the debugging interface of managers from the operator's operation interface.
