Brief introduction of HY-8.7 series generator
1. HY-8.7 intelligent series is another masterpiece of our company that took ten years to build from 2008 to 2018. It uses a high-performance anti-interference microprocessor to realize electronic control . All parameters of welding control are carried out by microcomputer. Management, intelligent frequency control system, eliminating the inconvenience of manual frequency adjustment, automatic detection of sound wave overload, real-time tracking of the best resonance point, keeping the temperature of the vibration group at the lowest point, and the frequency change following the temperature rise of the welding head, the machine automatically adjusts the operation more stable.
2, Principle of Ultrasonic Welding
When the ultrasonic wave acts on the metal contact surface, it will generate tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration with a certain amplitude will transmit the ultrasonic energy to the welding area through the upper weldment. Since the welding area is the two welded The acoustic resistance at the interface is large, so local high temperature will be generated. Due to the poor thermal conductivity of the metal, it cannot be dissipated in time for a while, and it gathers in the welding area, causing the contact surface of the two metals to melt rapidly, and after a certain pressure is added, it is fused into one. When the ultrasonic wave stops working, let the pressure continue for a few seconds to make it solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw material. The quality of ultrasonic metal welding depends on three factors: the amplitude of the transducer horn, the applied pressure and the welding time. The welding time and the pressure of the horn can be adjusted, and the amplitude is controlled by the transducer and the amplitude. Rod decides. There is an appropriate value for the interaction of these three quantities. When the energy exceeds the appropriate value, the melting amount of the metal will be large, and the weld will be easily deformed; This optimal pressure is the product of the side length of the welded part and the optimal pressure per 1 mm of the edge.
3. Features of HY-8.7 generator
1. High stability: All-digital integrated circuit adopts high-performance anti-interference processor imported from the United States, reduces the number of components, simplifies the hardware structure, and increases the voltage stabilization function to improve the reliability and stability of the system.
2. Automatic frequency tracking: digital frequency synthesis technology combined with digital phase-locked loop frequency tracking compound control technology can eliminate the shortcomings of temperature, static load, processing area, tool wear and other factors that are difficult to overcome by conventional analog regulators, which is conducive to parameter adjustment , It is convenient to adjust the control scheme and realize a variety of new control strategies through the modification of the program software.
3. Strong output: The application of IGBT power module and the structure of the externally excited oscillation circuit make the output power more than 1.5 times that of the traditional self-excited circuit .
4. Amplitude stepless adjustment: The amplitude can be increased or decreased instantaneously during the adjustment process, and can also be fine-tuned, which can effectively prevent the perfect welding of large and small plastic parts, effectively reduce shock wear and burns, and has the function of defective product monitoring, which is more suitable for automatic supporting use. Amplitude setting range 10%~100%
Intelligent protection and fault alarm prompt: mold current over-high protection, frequency offset protection, total output over-large protection. If the equipment breaks down, the generator will stop working immediately, and will give a corresponding prompt for the cause of the failure until the technician eliminates the failure.
The amplitude adjustment realized by the intelligent closed-loop amplitude control technology maintains a constant amplitude output without being affected by the fluctuation of the input power supply voltage and load.
A variety of welding mode switching, so that the welding precision is higher, the application range is wider, and the welding effect is better.
