Hydraulic System
Our hydraulic system is truly a masterpiece. Thoughtfully assembled with a high-precision gear pump, a complex valve group, and superior auxiliary pipelines, it guarantees flawless operation.
The hydraulic valve incorporates the renowned Yuken superposition series, brilliantly ensuring that the pipeline layoutis
remarkably intuitive, significantly minimizing leakage and streamlining maintenance, leading to outstanding efficiency.
This sophisticated system architecture comprises three distinct loops: the pressure adjusting loop, the synchronization loop, and the speed loop, each meticulously designed to contribute to harmonious and efficient operations.
The pressure adjusting loop expertly modulates the system’s working pressure via the main overflow valve, achieving a robust 16Mpa, ensuring consistent and reliable performance.
The synchronization loop deftly fine-tunes the synchronized movement of the lower roller through precise flow dividers and throttle valves, allowing for impeccable speed adjustments.
The speed loop gracefully governs frame descent, reset operations, and speed calibrations with precision, utilizing the adept throttle valve.
Electric Control System
Our electric control system is an engineering marvel, featuring a seamlessly integrated electric cabinet, an advanced operation control table, and a versatile portable button box, all operating at 380V/50Hz. It is equipped with robust short circuit and overload protection for the main motor, employing an AC contactor to manage both positive and reverse rotations. Powered by PLC programmable control technology, this system minimizes relay usage, enhancing stability and longevity. Strategically placed buttons and indicator lights on the control table ensure the entire rolling process is streamlined, efficiently managing every operational aspect with precision.
CNC System
The NC system is a model of reliability, featuring a rotational encoder and a high-reliability industrial controller, creating a steadfast and dependable control platform.
CNC Function
CThis advanced NC system offers unparalleled real-time monitoring, effortless data transmission, and dependable power-off memory throughout the entire rolling process, ensuring both efficiency and reliability.
The industrial control PLC meticulously inspects the lower position and both ends of the side roller, guaranteeing synchronization precision with an impressive ±0.15mm accuracy.
The state-of-the-art programmable display provides comprehensive real-time visibility of the lower roller and side roller end positions,
and these parameters can be effortlessly configured and set to meet precise requirements with ease.
