Our cutting-edge Advanced Four Rollers Machine for Precision Steel Plate Processing is a true marvel, engineered with a sophisticated four-roller design. The top roller stands as the pivotal component, orchestrating the entire process with unparalleled precision. It serves as the primary drive, executing smooth rotational movements. Meanwhile, the lower roller, with its seamless vertical motion, elegantly guides the plate, maintaining perfect friction alignment along its length. The side rollers operate with graceful precision, moving at specific angles to impart the desired plastic deformation to the steel plate. With the adjustable side roller, this remarkable machine offers both symmetric and asymmetric bending capabilities, minimizing flat ends. It surpasses the limitations of traditional three-roller machines by eliminating the necessity for pre-bending procedures and devices, providing the additional benefit of rough leveling the steel plate. This innovation is indispensable in industries including petroleum, chemical, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.

top roller and driving assembly
The Top roller device is a marvel of engineering, comprising the top roller, a hydraulically controlled drop end, fixed bearing, hydraulic motor, and bearing.
The top roller seamlessly transfers torque through its hydraulic motor, initiating precise rotation. A protective steel bushing is elegantly fitted with the hydraulic drop end for enhanced safety.
movement. The hydraulic drop end is equipped with a robust protective steel bushing.
lower roller and position inspection unit
The lower roller device is meticulously designed, featuring the lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing.
Each sliding bearing block, integral to the lower roller, aligns perfectly with the frame guide rail. It's mounted on two oil cylinders, where the hydraulic system delivers precise up-down movement power for the lower roller. Operating at a rated pressure of 16Mpa, the main oil cylinder ensures optimal performance. Sensors accurately track the up-down distance, displaying it on an LCD for easy monitoring. The hydraulic system's adjustable pressure guarantees precise hydraulic power to meet the desired rolling force with exacting standards.

side roller apparatus
The side roller device is intricately engineered, featuring the main oil cylinder, self-aligning bearing, and additional bearings, ensuring flawless functionality.
Bearing blocks strategically support the side roller, working in perfect harmony with the frame's guide rail.
The side roller bearing block's meticulous up-down movement is driven by four strategically positioned oil cylinders within the frame. Sensors installed on the side rollers and frame meticulously measure the movement, presenting results on an LCD for precise analysis.
To create an exquisite cone shape, self-aligning bearings are utilized for the side and lower rollers. With the lower roller level and alignment becoming inclined, refined adjustments enable a perfect fit between lower and side rollers, introducing an ideal degree of inclination relative to the horizontal, leading to outstanding results.
3-4, hydraulic drop end
The hydraulic drop end device comprises oil cylinders, joints, bearing blocks, and other components, ensuring seamless operation.
The hydraulic drop end system facilitates the effortless removal of products along the Roller shaft, optimizing productivity and efficiency.
Upon the completion of hydraulic drop closure or opening, the oil cylinder's stroke seamlessly resets to zero, maintaining system integrity.The power source is a reliable, precision-engineered hydraulic station, ensuring consistent and dependable operation.
Balance device
Our state-of-the-art balance device is ingeniously crafted with a cutting-edge, compact structure, ensuring unparalleled performance. When the tipping rack gracefully slips off the bearing face of the top roller and initiates its tipping movement, this advanced balance device comes into play. As gravity naturally draws the top roller's end downwards, this expertly designed apparatus maintains perfect equilibrium by being thoughtfully positioned on the fixed side. This strategic placement, at a meticulously calculated distance from the fixed frame, is firmly anchored by high-quality screws, guaranteeing stability and exceptional operational efficiency.

Hydraulic System
Our cutting-edge hydraulic system is a masterpiece of modern engineering, meticulously assembled from a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines to ensure flawless operation, combining technology with craftsmanship.
The hydraulic valve features the acclaimed Yuken superposition series, which ingeniously ensures that the pipeline layoutis
astonishingly intuitive, significantly reducing leakage and simplifying maintenance for exceptional efficiency, making every operation seamless.
This sophisticated system architecture incorporates three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each meticulously contributing to a harmonious and efficient operation, optimizing every process with precision.
The pressure adjusting loop expertly modulates the system’s working pressure utilizing the main overflow valve, achieving a robust working pressure of 16Mpa, ensuring consistent and reliable performance.
The synchronization loop deftly fine-tunes the in-sync movement of the lower roller through the precise flow divider and throttle valve, allowing for impeccable speed adjustments, ensuring perfect alignment.
The speed loop artfully manages frame descent, reset operations, and speed calibrations with precision, through the adept use of the throttle valve, ensuring fluid and efficient transitions.
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 functioning at 380V/50Hz. Equipped with robust short circuit and overload protection for the main motor, and utilizing an AC contactor for managing both positive and reverse rotations. Through the power of PLC programmable control technology, this system boasts minimal relay usage, enhancing stability and longevity. Strategically placed buttons and indicator lights on the control table ensure the entire rolling process is streamlined and efficiently managed, with every operational aspect scrutinized with precision.
CNC System
The NC system is a paragon of reliability, designed with a rotational encoder and a high-reliability industrial controller, creating a steadfast and dependable control system that brings cutting-edge technology to your fingertips.
CNC Function
CThis advanced NC system offers unparalleled real-time monitoring, effortless data transmission, and dependable power-off memory throughout the entire rolling process, ensuring efficiency and reliability, providing users with peace of mind at every step.
