Product Description

Discover the Future of Steel Bending with our Advanced Four Rollers Machine! This state-of-the-art, four-roller plate rolling marvel elevates precision to new heights. The pivotal top roller drives the exceptional craftsmanship and finesse our discerning customers expect, ensuring consistently superior results. Serving as the primary drive, this machine executes rotational movements with unmatched grace. The lower roller gracefully ascends and descends, seamlessly guiding the plate into perfect alignment through its controlled friction. The two side rollers, with their smooth angular motions, deliver the precise plastic deformation needed for impeccable steel plate shaping. With its adjustable side roller, the machine effortlessly transitions between symmetric and asymmetrical bending, minimizing flat ends and rendering traditional three-roller machines obsolete by eliminating cumbersome pre-bending processes. This innovation also provides rough leveling, making it an indispensable asset across diverse sectors such as petroleum, chemical production, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.

Machine Construction Overview:
The sophisticated core of this machine includes an upper roller device paired with a powerful driving unit, a lower roller device,side rollerapparatus, a hydraulic drop end system, a state-of-the-art lubrication unit, durable left and right frames, and a robust chassis.

Top Roller and Driving Assembly
The Top roller device is a harmonious blend of a top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and essential bearings, all working in unison.
Here, the top roller transmits torque via its adeptly connected hydraulic motor, initiating smooth, seamless rotation. Additionally, a meticulously fitted protective steel bushing fortifies the hydraulic drop end.
movement. This expertly equipped hydraulic drop end ensures seamless operation through its protective steel bushing.


Lower Roller and Position Inspection Unit
The lower roller device is engineered with precision, featuring a lower roller, oil cylinder, lower roller bearing, and an innovative self-aligning bearing.
Sliding bearing blocks provide flawless alignment with the frame guide rail, ensuring optimal support for the lower roller. A pair of oil cylinders power its up-down motion via a hydraulic system operating at a rated pressure of 16Mpa. Sensors meticulously track movement distances, displaying data on an LCD for precision monitoring, ensuring the hydraulic system delivers the exact rolling force required for top-tier accuracy.

Side Roller Apparatus
Crafted with precision, the side roller device integrates the main oil cylinder, self-aligning bearing, and essential bearings.
The bearing blocks lend unwavering support to the side roller, with each side seamlessly coordinating with the frame's guide rail for absolute functionality.
Four strategically positioned oil cylinders drive the up-down movement of the side roller bearing block. Sensors installed on both the side rollers and frame provide meticulous movement readings, conveniently displayed on an LCD for easy monitoring.
Achieve a stunningly refined cone shape using self-aligning bearings on both side and lower rollers. By adjusting the lower roller level and alignment to incline, precision fine-tuning ensures a perfect fit between the lower and side rollers, introducing a precise inclination relative to the horizontal.
3-4, Hydraulic Drop End
Engineered for excellence, the hydraulic drop end device comprises robust oil cylinders, joints, bearing blocks, and more, ensuring peak efficiency.
The Hydraulic Drop End System is designed for effortless product removal along the roller shaft, streamlining your operations with ease.
Upon completing hydraulic drop closure or opening, the oil cylinder's stroke is expertly reset to zero, maintaining flawless precision and ensuring continued operational excellence.The power source, a marvel of modern engineering, is reliably provided by a state-of-the-art hydraulic station. This ensures unwavering and consistent performance, elevating the efficiency of our Advanced Four Rollers Machine for Customizable Steel Bending Projects.
Balance device
Ingeniously crafted to redefine balance, our state-of-the-art device features a cutting-edge, compact structure that ensures unmatched performance. As the tipping rack glides seamlessly from the bearing face of the top roller, embarking on its graceful tipping motion, this advanced balance apparatus springs into action. With gravity gently pulling the top roller's end downward, this expertly designed mechanism maintains perfect equilibrium, strategically positioned on the fixed side. This precise placement, calculated meticulously from the fixed frame, is firmly anchored by premium screws, guaranteeing unwavering stability and exceptional operational efficiency.

Hydraulic System
Our hydraulic system is a true masterpiece, meticulously assembled with a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, ensuring flawless operation with every use.
The hydraulic valve incorporates the esteemed Yuken superposition series, ingeniously ensuring that the pipeline layoutis
remarkably intuitive, dramatically reducing the risk of leakage and simplifying maintenance, culminating in exceptional operational efficiency.
This sophisticated architecture boasts three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop. Each component meticulously contributes to harmonious and efficient operations, ensuring every process runs smoothly.
The pressure adjusting loop deftly modulates the system's working pressure via the main overflow valve, achieving a robust pressure of 16Mpa. This guarantees consistent and reliable performance, no matter the challenge.
The synchronization loop skillfully fine-tunes the synchronized movement of the lower roller with precise flow dividers and throttle valves, allowing impeccable speed adjustments that redefine precision.
The speed loop artfully governs frame descent, reset operations, and speed calibrations with precision, utilizing the adept throttle valve to adjust with accuracy and ease.

Electric Control System

Our electric control system is a marvel of modern engineering, featuring an elegantly integrated electric cabinet, an advanced operation control table, and a versatile portable button box, all operating 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. 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, managing every operational aspect with precision and ease.

CNC System

The NC system is a hallmark of reliability, featuring a rotational encoder and a high-reliability industrial controller. This creates a steadfast and dependable control platform that ensures precision and efficiency.
CNC Function
CThis advanced NC system provides unparalleled real-time monitoring, effortless data transmission, and dependable power-off memory throughout the rolling process, ensuring efficiency and reliability at every step.
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, setting new standards for excellence.
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, enhancing customization and control.
With an extraordinary displacement transducer resolution of 0.10mm, the display precision achieves an impressive ±0.10mm accuracy, ensuring every detail is captured with clarity.
