Description

Technical Field

[0001] This utility model relates to the field of rolled product processing, and in particular to a servo control system for intelligent clamping rollers for high-speed wire rods. Background Technology

[0002] In traditional high-speed wire rod production lines, pinch rollers are mainly controlled by asynchronous motors or DC motors. The main characteristic of this control method is the use of frequency converters or DC speed controllers to directly drive the motor. The advantages of this control method are: mature and reliable technology, stable system operation, lower cost, simple selection, simple structure, and easy maintenance.

[0003] However, traditional control methods mainly use microcontrollers and integrated circuits to control high-power electrical components. Due to the development of electronic circuits, this control method is significantly outdated compared to modern control methods. Compared to modern servo control systems, the original control systems mostly use tachometers or incremental encoders for speed measurement, resulting in lower sampling frequency and accuracy, and slower feedback speed. The AC frequency conversion and DC control methods for transmission do not use feedback units, resulting in low power factor and high energy consumption. Furthermore, the relatively simple structure and outdated control methods mean that the equipment cannot reach higher speeds, and the vibration value is too large when operating at high speeds, making the equipment prone to damage.

[0004] In summary, a high-speed intelligent wire feeding roller servo control system needs to be designed to detect speed, save energy, and improve operating speed, thereby adapting to changing production needs and improving overall manufacturing efficiency. Utility Model Content
