Introducing a cutting-edge marvel in plate rolling technology – our Customizable Steel Roll Machine redefines precision and efficiency. With the top roller as the heart of this four-roller system, it guarantees the finesse and accuracy that our esteemed customers demand. It serves as the primary drive, executing seamless rotational movements with unparalleled grace. The lower roller ascends and descends with elegance, guiding the plate with exactitude, while maintaining perfect friction for lengthwise alignment. The side rollers, with their dynamic and fluid angular motion, artfully sculpt the desired plastic deformation into the steel plate. The adaptable side roller empowers the machine to achieve both symmetric and asymmetrical bending effortlessly, minimizing flat ends and eliminating the need for cumbersome pre-bending devices. Beyond traditional three-roller machines, it also facilitates rough leveling of steel plates, becoming an indispensable tool across industries such as petroleum, chemical production, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.

top roller and driving assembly
The Top roller device features a top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and bearing, all harmoniously operating together.
The top roller transmits torque through its integrated hydraulic motor, ensuring a smooth and flawless rotation. A meticulously fitted steel bushing protects the hydraulic drop end, ensuring seamless operation.
movement. This hydraulic drop end is expertly equipped with a protective steel bushing to ensure seamless operation.
lower roller and position inspection unit
The lower roller apparatus includes a lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing, all engineered for optimal efficiency.
Each sliding bearing block perfectly aligns with the frame guide rail, supporting the lower roller. Two oil cylinders power the vertical movement of the lower roller. The primary oil cylinder operates at a rated pressure of 16Mpa, while sensors meticulously monitor the up-down distance, displaying the data on an LCD. This adjustable hydraulic system guarantees precise power delivery for desired rolling force, advancing accuracy to unprecedented levels.

side roller apparatus
The side roller device is expertly designed with a main oil cylinder, self-aligning bearing, and other crucial components.
Bearing blocks steadfastly support the side roller, with seamless coordination with the frame's guide rail for optimal functionality.
The vertical movement of the side roller bearing block is powered by four strategically positioned oil cylinders. Sensors on both side rollers and the frame meticulously measure the movement, which is displayed on an LCD for straightforward monitoring.
Achieving a stunningly exquisite cone shape is made possible with self-aligning bearings for both side and lower rollers. With careful adjustment, the lower roller level can be inclined, allowing for a snug fit and precise inclination relative to the horizontal.
3-4, hydraulic drop end
The hydraulic drop end device, featuring robust oil cylinders, joints, bearing blocks, and more, ensures unmatched efficiency.
The hydraulic drop end system effortlessly enables product removal along the Roller shaft, streamlining operations.
Upon completing hydraulic drop closure or opening, the stroke of the oil cylinder is ingeniously reset to zero, ensuring precision.A state-of-the-art hydraulic station reliably provides power, ensuring consistent and superior 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 a true masterpiece of engineering excellence. Meticulously assembled with a high-precision gear pump, intricate valve group, and premium auxiliary pipelines, it ensures flawless and reliable operation throughout its lifecycle.
The hydraulic valve incorporates the renowned Yuken superposition series, ingeniously ensuring that the pipeline layoutis
remarkably intuitive, dramatically reducing leakage and simplifying maintenance, which culminates in exceptional operational efficiency and user-friendly maintenance.
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 and reliable 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 for optimal output.
The speed loop artfully governs frame descent, reset operations, and speed calibrations with precision, utilizing the adept throttle valve to ensure smooth and efficient operations.
Electric Control System
Our electric control system stands as a marvel of engineering innovation, 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, thus 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 utmost 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 designed for optimal performance.
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, ensuring high-standard performance.
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, ensuring precision and accuracy in every operation.
With an extraordinary displacement transducer resolution of 0.10mm, the display precision achieves an impressive ±0.10mm accuracy, affirming the system's excellence.
