Introducing a technological masterpiece: a four-roller plate rolling sensation that redefines precision and elegance. At the heart of this cutting-edge marvel lies the top roller, a key driving force that elevates the standards of excellence and refinement our esteemed clientele demands. It serves as the cornerstone of performance, leading the rotational dance with unmatched poise. The sophisticated lower roller performs a graceful ascent and descent, masterfully guiding the plate to perfection while maintaining impeccable friction for flawless alignment. The innovative side rollers, with their dynamic angular motion, seamlessly mold the steel plate into the desired form with unparalleled plastic deformation. Remarkably versatile, the adjustable side roller allows effortless execution of both symmetric and asymmetrical bending, minimizing flat ends and transcending traditional three-roller machines by eliminating the need for cumbersome pre-bending techniques. This machine stands as an irreplaceable asset across diverse sectors such as petroleum, chemical production, boiler manufacturing, shipbuilding, hydroelectric power, metal structures, and advanced machinery.
Machine construction:
The engineering ingenuity of this advanced machine is reflected in its integral components comprising the upper roller mechanism, a sophisticated driving unit, lower roller apparatus,andside roller system. Additional features include a hydraulic drop end mechanism, an efficient lubrication system, sturdy left and right frames, and a durable chassis, among others.

Top roller and driving assembly
The Top roller mechanism boasts an assembly of a top roller, hydraulic drop end, fixed bearing, hydraulic motor, and accompanying bearings, all harmoniously synchronized.
The top roller gracefully transmits torque through a seamlessly connected hydraulic motor, initiating its fluid rotation. A meticulously crafted protective steel bushing complements the hydraulic drop end.
movement. This hydraulic drop end is expertly outfitted with a protective steel bushing, ensuring flawless operation.
Lower roller and position inspection unit
The lower roller apparatus is a composite of a lower roller, oil cylinder, lower roller bearing, and self-aligning bearing, all meticulously engineered for pinnacle performance.
Each sliding bearing block, supporting the lower roller, aligns with pristine precision along the frame's guide rail. Powered by a hydraulic system mounted on dual oil cylinders, the lower roller's elevation is effortlessly controlled. The primary oil cylinder operates under a rated pressure of 16Mpa, while sensors meticulously monitor the up-down distance, displaying this data on an advanced LCD system. This adjustable hydraulic system guarantees precise power delivery, meeting the desired rolling force with elevated accuracy.

Side roller apparatus
The side roller mechanism is masterfully crafted, comprising the main oil cylinder, self-aligning bearings, and crucial support bearings.
Bearing blocks offer unwavering stability to the side roller, each side harmoniously integrating with the frame's guide rail for optimal operation.
The ascension and descent of the side roller bearing block are powered by four strategically arranged oil cylinders within the frame. Precision sensors, integrated into both the side rollers and frame, accurately gauge movement, displaying this on a convenient LCD for effortless monitoring.
To achieve a remarkably refined cone shape, self-aligning bearings are utilized for both side and lower rollers. With a refined adjustment of the lower roller level and alignment, an inclined position is achieved, ensuring a snug fit between the lower and side rollers. This introduces an exact degree of inclination in relation to the horizontal.
3-4, Hydraulic drop end
The hydraulic drop end device encompasses robust oil cylinders, joints, bearing blocks, and additional components, ensuring superior efficiency.
The hydraulic drop end system guarantees seamless product removal along the Roller shaft, streamlining and simplifying operations with remarkable ease.
Upon completion of hydraulic drop closure or opening, the oil cylinder's stroke is ingeniously reset to zero, maintaining impeccable precision and operational integrity.The power source is reliably provided by a state-of-the-art hydraulic station, ensuring consistent performance.
Balance device
Ingeniously crafted to revolutionize balance, our state-of-the-art device boasts a cutting-edge, compact structure that ensures unparalleled performance. When the tipping rack elegantly slips from the bearing face of the top roller and begins its graceful tipping motion, this advanced balance apparatus steps into action. As gravity naturally tugs the top roller's end downward, this expertly designed mechanism maintains perfect equilibrium, strategically positioned on the fixed side. This precise placement, at a meticulously calculated distance from the fixed frame, is securely anchored by premium screws, guaranteeing unwavering stability and exceptional operational efficiency.

Hydraulic System
Our hydraulic system is nothing short of a masterpiece. Meticulously assembled with a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, it ensures flawless operation.
The hydraulic valve incorporates the renowned Yuken superposition series, ingeniously ensuring that the pipeline layoutis
remarkably intuitive, dramatically reducing leakage and simplifying maintenance, culminating in exceptional efficiency.
This sophisticated architecture boasts three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each meticulously contributing to harmonious and efficient operations.
The pressure adjusting loop skillfully modulates the system’s working pressure via the main overflow valve, achieving a robust pressure of 16Mpa, ensuring consistent performance.
The synchronization loop deftly fine-tunes the synchronized movement of the lower roller through precise flow dividers and throttle valves, allowing impeccable speed adjustments.
The speed loop artfully governs frame descent, reset operations, and speed calibrations with precision, utilizing the adept throttle valve.
Electric Control System
Our electric control system is a marvel of engineering, 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 for managing both positive and reverse rotations. Through the power of 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 paragon 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 provides unparalleled real-time monitoring, effortless data transmission, and dependable power-off memory throughout the entire rolling process, ensuring 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 offers 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 an extraordinary displacement transducer resolution of 0.10mm, the display precision achieves an impressive ±0.10mm accuracy.
