Technical requirements for ultrasonic metal welding machine
1. High power capacity and stable ultrasonic generator
The first requirement of a stable ultrasonic generator is: automatic frequency tracking. Frequency automatic tracking can ensure that the transducer system can work in resonance, that is, the maximum amplitude of the welding head. The use of automatic frequency tracking technology, no need to adjust the frequency when changing molds and working, is the basic requirement for metal welding. The equipment with adjustable inductance and manual frequency adjustment basically cannot meet the requirements.
A stable ultrasonic generator also requires: constant amplitude function and stepless adjustment of amplitude. Constant amplitude function, which can ensure the consistency of welding, is the key to stable production; the stepless adjustment of amplitude is the basic to ensure the use of equipment, such as welding copper and aluminum materials through parameter adjustment on the same equipment.
High power capacity: Compared with plastic welding, metal welding requires a higher energy density and must have a relatively high power capacity. For example, a 20kHz machine basically requires a power capacity of more than 3000W. Many companies often have false ratings for power capacity, so we only need to compare them with the plastic welding machines they make, because no one believes that the plastic welding machine is too high.
2, high-quality welding head
As an industrial application, metal welding inevitably requires a long-life welding head.
3, high-quality transducer
For example, a 20kHz transducer must be able to withstand a load above 3kw for a long time. The transducers of many companies, which are welded with ordinary plastic, are difficult to distinguish in appearance, which is irresponsible.
4, high-quality control system
has three basic control modes of welding energy, time and height, and a variety of quality control software to meet different needs.
