Step into the future of efficient plate rolling with our cutting-edge machine! This four-roller, plate rolling wonder is engineered with the top roller as its key player. It drives the unparalleled precision and artistry that our discerning customers demand, making it a testament to advanced technology. It serves as the primary drive, executing rotational movements with elegance and grace. The lower roller, with its sophisticated ascent and descent, guides the plate seamlessly, ensuring friction aligns it perfectly along its length. The two side rollers, with their fluid and dynamic angular motion, induce the desired plastic deformation to the steel plate. Thanks to the expertly adjustable side roller, our machine effortlessly performs both symmetric and asymmetrical bending with an impressively minimal flat end. It surpasses the capabilities of traditional three-roller machines by eliminating cumbersome pre-bending procedures and devices. Additionally, it provides rough leveling of the steel plate, making it an invaluable asset across various industries including petroleum, chemical production, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.
Machine construction:
The core structure of this highly sophisticated machine consists of the upper roller device and its driving unit, lower roller device, side roller apparatus, hydraulic drop end system, lubrication unit, durable left and right frames, a robust chassis, and more.

top roller and driving assembly
The Top roller device incorporates a top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and associated bearings, all harmoniously working in unison.
The top roller transmits torque through a connected hydraulic motor, initiating its smooth and effortless rotation. A protective steel bushing is meticulously installed in conjunction with the hydraulic drop end.
movement. This hydraulic drop end is adeptly equipped with a protective steel bushing to guarantee seamless operation.
lower roller and position inspection unit
The lower roller device is comprised of a lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing, all meticulously designed for optimal performance.
Each sliding bearing block, which supports the lower roller, aligns with utmost precision to the frame guide rail. Mounted on two oil cylinders, the hydraulic system powers the up-down movement of the lower roller. The primary oil cylinder operates at a rated pressure of 16Mpa, while finely-tuned sensors track the up-down distance, displaying the data on an LCD. This adjustable hydraulic system ensures precise power to meet the desired rolling force, enhancing accuracy to an unparalleled level.

side roller apparatus
The side roller device is crafted with precision, featuring the side roller's main oil cylinder, self-aligning bearing, and other vital bearings.
Bearing blocks offer unwavering support to the side roller, with each side seamlessly coordinating with the frame's guide rail for optimal functionality.
The up-down movement of the side roller bearing block is driven by four strategically positioned oil cylinders within the frame. Sensors, placed thoughtfully on both the side rollers and frame, carefully measure the movement, which is displayed on an LCD for easy and precise monitoring.
To create a stunningly exquisite cone shape, self-aligning bearings are employed for both side and lower rollers. With the lower roller level and alignment adjusted to become inclined, fine-tuning achieves a precise fit between lower and side rollers, introducing an exact degree of inclination relative to the horizontal.
3-4, hydraulic drop end
The hydraulic drop end device includes robust oil cylinders, joints, bearing blocks, and more, ensuring unparalleled efficiency.
The hydraulic drop end system ensures the effortless removal of products along the Roller shaft, streamlining the entire operation.
After completing hydraulic drop closure or opening, the oil cylinder's stroke is ingeniously reset to zero, preserving precision and reliability.The power source is securely provided by a state-of-the-art hydraulic station, ensuring consistent and reliable 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 truly a masterpiece, meticulously assembled with a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, ensuring 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.
