At the forefront of innovation, this state-of-the-art machine stands as a four-roller plate rolling marvel, where the top roller reigns supreme as the pivotal component. It serves as the primary drive, executing rotational movements with precision. The lower roller gracefully moves up and down to guide the plate with elegance, ensuring that friction aligns seamlessly lengthwise. The two side rollers ascend and descend at an angle to impart the desired plastic deformation to the steel plate. With its adjustable side roller, this machine adeptly achieves both symmetric and asymmetrical bending, resulting in minimal flat ends, outperforming three-roller machines by eliminating the need for pre-bending procedures and devices. Furthermore, it provides rough leveling of the steel plate, making it indispensable across industries such as petroleum, chemical, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.
Machine construction:
The refined core structure of this sophisticated machine includes an upper roller device and driving unit, lower roller device, side roller apparatus, hydraulic drop end system, lubrication unit, left and right frames, chassis, and more.

top roller and driving assembly
The Top roller device comprises the top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and bearing.
The top roller channels torque through a connected hydraulic motor, initiating smooth rotation. A protective steel bushing is thoughtfully fitted with the hydraulic drop end.
movement. The hydraulic drop end comes equipped with a robust protective steel bushing.
lower roller and position inspection unit
The lower roller device comprises the lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing.
Each sliding bearing block, supporting the lower roller, aligns with the frame guide rail for optimal precision. Mounted on two oil cylinders, the hydraulic system delivers the up-down movement power for the lower roller, operating at a rated pressure of 16Mpa. Sensors meticulously track the up-down distance, displaying it on an LCD for real-time monitoring. The hydraulic system's adjustable pressure ensures the delivery of precise hydraulic power to meet the desired rolling force.

side roller apparatus
The side roller device is intricately composed of the side roller's main oil cylinder, self-aligning bearing, and additional bearings.
Bearing blocks provide steadfast support for the side roller, with each side coordinating seamlessly with the frame's guide rail.
The up-down movement of the side roller bearing block is driven with precision through four strategically placed oil cylinders within the frame. Sensors installed on the side rollers and frame measure the movement, with results prominently displayed on an LCD.
To craft an exquisite cone shape, self-aligning bearings are skillfully employed for both side and lower rollers. As the lower roller levels and its alignment becomes inclined, fine adjustments enable a snug fit between lower and side rollers, introducing a precise degree of inclination relative to the horizontal.
3-4, hydraulic drop end
The hydraulic drop end device comprises oil cylinders, joints, bearing blocks, and more.
The hydraulic drop end system enables effortless product removal along the Roller shaft with finesse.
Upon completion of hydraulic drop closure or opening, the oil cylinder's stroke is elegantly reset to zero.The power source is derived from a dependable hydraulic station.
Balance device
Introducing our state-of-the-art balance device, meticulously engineered with an innovative compact structure that ensures optimal performance. This superior mechanism comes into action when the tipping rack slips off the top roller's bearing face, initiating the tipping movement. As gravity causes the top roller's end to descend, our advanced balance device masterfully maintains equilibrium. Strategically positioned on the fixed side, it creates a calculated distance from the fixed frame. This design is securely fastened by screws, ensuring unmatched stability and efficiency throughout the process.

Hydraulic System
Our hydraulic system is an epitome of precision engineering, crafted from a high-precision gear pump, a sophisticated valve group, and auxiliary pipelines that harmonize seamlessly for flawless operation.
The hydraulic valve employs the esteemed Yuken superposition series, ensuring the pipeline layoutis
wonderfully straightforward, significantly minimizing leakage and simplifying maintenance, culminating in unparalleled operational efficiency.
The system's architecture features three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop. Each loop plays a vital role in ensuring a harmonious and efficient operation.
The pressure adjusting loop expertly modulates the system's working pressure through the main overflow valve, delivering a robust working pressure of 16Mpa.
The synchronization loop fine-tunes the in-phase movement of the lower roller using precision components like the flow divider and throttle valve, allowing for exact speed adjustments.
The speed loop precisely manages frame descent, reset operations, and speed adjustments through the expertly designed throttle valve.
Electric Control System
Our electric control system features an integrated, cutting-edge electric cabinet, a sophisticated operation control table, and a portable button box, all operating seamlessly at 380V/50Hz. Equipped with robust short circuit and overload protection for the main motor, it employs an AC contactor to manage both positive and reverse rotations. Leveraging PLC programmable control technology, it boasts minimal relay usage, thereby enhancing stability and longevity. Strategically placed buttons and indicator lights on the control table streamline the rolling process, overseeing every aspect of operation with precision and ease.
CNC System
The NC system is ingeniously designed with a rotational encoder and a high-reliability industrial controller, creating a consistent and reliable control framework. CNC Function
CThis advanced NC system provides real-time monitoring, seamless data transmission, and dependable power-off memory throughout the rolling process, ensuring consistent performance.
The industrial control PLC automatically checks the lower position and both ends of the side roller, maintaining synchronization precision within ±0.15mm.
The programmable display offers real-time visibility of the lower roller and side roller end positions,
and these parameters can be effortlessly configured and set to meet specific operational needs.
With a displacement transducer resolution of 0.10mm, the display precision achieves a remarkable ±0.10mm, providing unparalleled accuracy.
