Introducing our cutting-edge Automatic CNC Bending Machine for Customizable Steel Sheet Forming, a remarkable four-roller plate rolling wonder. At its core, the top roller stands as the machine's pivotal element, orchestrating the precision and elegance that our valued customers have come to expect. It serves as the primary drive, executing rotational movements with unparalleled grace. The lower roller ascends and descends with an elegant touch, guiding the plate with unparalleled precision, while the friction ensures it is perfectly aligned lengthwise. The two side rollers, with their seamless up-and-down angular motion, impart the desired plastic deformation to the steel plate. With its adjustable side roller, the machine effortlessly achieves both symmetric and asymmetrical bending with minimal flat ends, transcending traditional three-roller machines by eliminating the need for cumbersome pre-bending procedures and equipment. It also offers rough leveling of the steel plate, rendering it an indispensable asset in industries such as petroleum, chemical production, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.

top roller and driving assembly
The Top roller device showcases a top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and bearing, all working harmoniously in concert.
The top roller channels torque through a seamlessly connected hydraulic motor, initiating its smooth and fluid rotation. A protective steel bushing is meticulously integrated with the hydraulic drop end.
movement. This expertly designed hydraulic drop end is equipped with a protective steel bushing to ensure seamless operation.
lower roller and position inspection unit
The lower roller device comprises a lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing, each element crafted for optimal performance.
Each sliding bearing block, which provides robust support to the lower roller, aligns flawlessly with the frame's 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, with sensors meticulously tracking the up-down distance and displaying the data on an LCD. This adjustable hydraulic system ensures precise power to achieve the desired rolling force, enhancing accuracy to the next level.

side roller apparatus
The side roller device is expertly crafted with the side roller's main oil cylinder, a self-aligning bearing, and other essential bearings.
Bearing blocks provide 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 powered by four strategically placed oil cylinders within the frame. Sensors, installed on both the side rollers and frame, meticulously measure the movement, which is displayed on an LCD for effortless monitoring.
To achieve a stunningly exquisite cone shape, self-aligning bearings are employed for both the side and lower rollers. With the lower roller level and alignment adjusted for inclination, fine-tuning achieves a snug fit between the lower and side rollers, introducing a precise 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 seamless efficiency.
The hydraulic drop end system ensures effortless product removal along the Roller shaft, streamlining operations with ease.
After completing the hydraulic drop closure or opening, the oil cylinder's stroke is ingeniously reset to zero, maintaining utmost precision.A state-of-the-art hydraulic station faithfully provides the power source, ensuring consistent and reliable performance.
Balance device
Ingeniously crafted to redefine the essence of balance, our innovative device features a state-of-the-art, compact architecture that delivers unmatched performance. As the tipping rack delicately departs from the top roller's bearing surface, entering its poised tipping motion, this advanced balance mechanism engages with precision. While gravity subtly draws the top roller's end downward, this expertly engineered apparatus maintains impeccable equilibrium, strategically located on the fixed side. Its exact placement, at a scientifically calculated distance from the fixed frame, is firmly secured by high-quality screws, ensuring steadfast stability and superior operational efficiency.

Hydraulic System
Our hydraulic system stands as a masterpiece of engineering excellence. Constructed with meticulous attention to detail, it features a high-precision gear pump, an intricate valve group, and top-tier auxiliary pipelines, guaranteeing flawless operation.
The hydraulic valve incorporates the distinguished Yuken superposition series, ingeniously designed to ensure the pipeline layoutis
remarkably intuitive, significantly minimizing leakage and simplifying maintenance, leading to exceptional efficiency.
This sophisticated system architecture encompasses three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each meticulously contributing to synchronized and efficient operations.
The pressure adjusting loop adeptly modulates the system’s working pressure with the main overflow valve, achieving a robust pressure of 16Mpa, ensuring consistent and dependable performance.
The synchronization loop deftly calibrates the synchronized movement of the lower roller using precise flow dividers and throttle valves, allowing flawless speed adjustments.
The speed loop artfully orchestrates frame descent, reset operations, and speed calibrations with precision, utilizing the proficient throttle valve.
Electric Control System
Our electric control system is an engineering marvel, featuring a seamlessly integrated electric cabinet, an advanced operation control table, and a versatile portable button box, all operating at 380V/50Hz. It offers robust short circuit and overload protection for the main motor, utilizing an AC contactor for managing both forward and reverse rotations. Leveraging the power of PLC programmable control technology, this system minimizes relay usage, enhancing stability and longevity. Strategically arranged buttons and indicator lights on the control table streamline the rolling process, efficiently managing every operational detail with precision.
CNC System
The NC system exemplifies reliability, featuring a rotational encoder and a high-reliability industrial controller, establishing a robust and dependable control platform.
CNC Function
CThis advanced NC system delivers unparalleled real-time monitoring, seamless data transmission, and reliable power-off memory throughout the entire rolling process, ensuring optimal efficiency and reliability.
