Resistance welding machine is a kind of equipment widely used in the field of metal welding, which has the advantages of high welding efficiency and low cost. The design and performance of the transformer and control system have an important impact on the welding quality and efficiency. This article will introduce in detail the basic principle, structure and working mode of the intermediate frequency resistance welding machine transformer and control system.
The transformer of the intermediate frequency resistance welding machine is an important part of the resistance welding machine, and its main function is to convert the alternating current of the power grid into the alternating current of low voltage and high current, and provide power supply for the control system and welding circuit of the resistance welding machine. The intermediate frequency resistance welding machine transformer usually adopts the structure of iron core and coil, and converts the alternating current of the power grid into low-voltage and high-current alternating current through the principle of electromagnetic induction.
The design of the intermediate frequency resistance welding machine transformer needs to consider many factors, such as the power, voltage, current and other parameters of the transformer, as well as the efficiency and temperature rise of the transformer. At the same time, the structure of the transformer also needs to take into account the stability, reliability and safety of the equipment.
The control system of the intermediate frequency resistance welding machine is the core part of the resistance welding machine, which is responsible for controlling the welding process, including welding time, welding current, welding temperature and other parameters. The control system is usually controlled by a microprocessor or programmable logic controller (PLC), which can be programmed and adjusted according to different welding needs and process requirements.
The design of the control system of the intermediate frequency resistance welding machine also needs to consider many factors, such as the accuracy, stability, and reliability of the control system. At the same time, the structure of the control system also needs to take into account the maintainability and scalability of the equipment.
It can be said that the intermediate frequency resistance welding machine transformer and control system have a wide range of applications in the field of metal welding, such as automobile manufacturing, home appliance manufacturing, etc. By using the intermediate frequency resistance welding machine, the welding quality and efficiency can be greatly improved, the production cost can be reduced, and the competitiveness of the enterprise can be improved. For example, Huandian medium frequency resistance welding machine transformer and control system.
This is a high-precision welding power supply, with 6 control modes, 5 working frequencies to choose from (1khz 2khz 3khz 4khz 5khz), servo motor control function, to achieve accurate adjustment of multi-stage welding pressure, adjustable sonotrode reset distance, and to solve the problem of instantaneous impact force under the cylinder type sonotrode.
The transformer and control system have a built-in database function, which can store the current, voltage, power, resistance, pressure, displacement and other teaching values of about 5 million solder joints, and support U disk export, which can monitor the average effective value and instantaneous value of current, voltage and power, and control the welding quality.
In short, the transformer and control system of the intermediate frequency resistance welding machine are an important part of the resistance welding machine, and their design and performance have an important impact on the welding quality and efficiency. With the continuous progress of science and technology and the continuous improvement of application requirements, the design and performance of intermediate frequency resistance welding machine transformers and control systems are also constantly optimized and improved.
