Embrace the future of industrial innovation with our cutting-edge Professional CNC Plate Bending Machine, an exquisite blend of technology and craftsmanship. This state-of-the-art marvel boasts a four-roller plate rolling mechanism, where the top roller stands as the pivotal element. It is the powerhouse behind the entire operation, serving as the primary drive and orchestrating rotational movements with precision. The lower roller, a masterpiece of engineering, gracefully ascends and descends to guide the plate, flawlessly aligning friction lengthwise. Meanwhile, the two side rollers elegantly adjust their position at an angle, masterfully crafting the desired plastic deformation into the steel plate. With a versatile adjustable side roller, this brilliant machine effortlessly accomplishes both symmetric and asymmetrical bending. It minimizes flat ends, outshining traditional three-roller machines by eliminating the cumbersome need for pre-bending procedures and devices, and simultaneously offering rough leveling of steel plates. Its versatility makes it an essential asset across various industries, including petroleum, chemical, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.
Machine construction:
The heart of this sophisticated machine lies in its intricately designed structure, featuring an upper roller device and driving unit, lower roller devicee, 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 is a symphony of engineering, comprising the top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and bearing.
Torque is efficiently transferred by the top roller through a connected hydraulic motor, setting the rotation in motion. A protective steel bushing accompanies the hydraulic drop end.
movement. The hydraulic drop end is expertly crafted, featuring a protective steel bushing.
Lower roller and position inspection unit
The lower roller device is a marvel of precision, encompassing the lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing.
Each sliding bearing block is meticulously aligned with the frame guide rail, supported by two oil cylinders. The hydraulic system imparts effortless up-down movement power to the lower roller, with the main oil cylinder operating at an impressive rated pressure of 16Mpa. Cutting-edge sensors track the up-down distance and display it on an LCD, while the hydraulic system's adjustable pressure ensures precise rolling force to meet diverse requirements.

Side roller apparatus
The side roller device is a complex ensemble, composed of the side roller's main oil cylinder, self-aligning bearing, and additional bearings.
Bearing blocks provide steadfast support for the side roller, each side harmoniously coordinating with the frame's guide rail.
The side roller bearing block's up-down movement is masterfully driven by four strategically positioned oil cylinders within the frame. Ingeniously placed sensors on the side rollers and frame measure the movement, presenting results elegantly on an LCD.
To craft an exquisite cone shape, the utilization of self-aligning bearings for both side and lower rollers is indispensable. As the lower roller levels and aligns, becoming inclined, precision adjustments ensure a snug fit between lower and side rollers, introducing a subtle degree of inclination relative to the horizontal.
3-4, Hydraulic drop end
The hydraulic drop end device is an intricate assembly of oil cylinders, joints, bearing blocks, and more.
The hydraulic drop end system facilitates effortless and seamless product removal along the Roller shaft, enhancing operational efficiency.
Upon the completion of hydraulic drop closure or opening, the oil cylinder's stroke resets to zero, ensuring precision and reliability.The hydraulic system, a paragon of dependability, is powered by a robust hydraulic station.
Balance device
Our state-of-the-art balance device is ingeniously crafted with a cutting-edge, compact structure, ensuring unparalleled performance and reliability. When the tipping rack gracefully slips off the bearing face of the top roller and initiates its tipping movement, this advanced balance device seamlessly comes into play. As gravity naturally draws the top roller's end downwards, our expertly designed apparatus maintains perfect equilibrium with precision. 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 unparalleled stability and exceptional operational efficiency.

Hydraulic System
Our cutting-edge hydraulic system is a masterpiece of engineering, meticulously assembled from a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, ensuring flawless operation and performance.
The hydraulic valve features the acclaimed Yuken superposition series, ingeniously ensuring that the pipeline layout isis
astonishingly intuitive and efficient, significantly reducing leakage and simplifying maintenance for exceptional operational efficiency.
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.
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 and enhanced precision.
The speed loop artfully manages frame descent, reset operations, and speed calibrations with unmatched precision, through the adept use of the throttle valve.
Electric Control System
Our electric control system is a marvel of engineering excellence, featuring a seamlessly 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, 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 and precision, designed with a rotational encoder and a high-reliability industrial controller, creating a steadfast and dependable control system for optimum performance.
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 unwavering efficiency and reliability.
The industrial control PLC meticulously inspects the lower position and both ends of the side roller, guaranteeing synchronization precision of an impressive ±0.15mm, ensuring unparalleled accuracy.
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 precisely set to meet specific requirements.
With an extraordinary displacement transducer resolution of 0.10mm, the display precision reaches an impressive ±0.10mm, offering exceptional accuracy.
