Introducing the cutting-edge marvel of engineering: Our Professional CNC Plate Bending Machine for Precision Steel Parts is a state-of-the-art, four-roller plate rolling wonder. At the heart of this sophisticated machine lies the top roller, the pivotal component that revolutionizes the bending process. It serves as the core element, playing a crucial role in the primary drive. Through its rotational movements, the machine orchestrates a symphony of precision as the lower roller ascends and descends with grace to guide the plate with refined ease, ensuring friction aligns perfectly lengthwise. Adding to this artistry, the two side rollers execute a delicate dance, moving up and down at an angle to impart the desired plastic deformation onto the steel plate. Embrace the versatility of this machine with its adjustable side roller, capable of achieving both symmetric and asymmetrical bending with impressive minimal flat ends. Unlike traditional three-roller machines, this innovation eliminates the need for pre-bending procedures and devices, offering rough leveling of the steel plate. This invaluable tool is indispensable across a spectrum of industries, including petroleum, chemical, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.
Machine construction:
The core structure of this sophisticated machine includes a meticulously designed upper roller device and driving unit, an innovative lower roller device, an advanced side roller apparatus, a hydraulic drop end system, an efficient lubrication unit, robust left and right frames, a durable chassis, and much more.

top roller and driving assembly
The Top roller device is an engineering feat, comprising the top roller, a sophisticated hydraulic drop end, fixed bearing, hydraulic motor, and bearing.
The top roller ingeniously transfers torque via a seamlessly connected hydraulic motor, setting the motion in a powerful rotation. A protective steel bushing accompanies the hydraulic drop end, providing unparalleled movement security.
movement. The hydraulic drop end is expertly equipped with a protective steel bushing to ensure durability.
lower roller and position inspection unit
The lower roller device is a masterpiece of precision engineering, consisting of the lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing.
Each sliding bearing block is designed to perfection, supporting the lower roller as it aligns seamlessly with the frame guide rail. Mounted on two robust oil cylinders, the hydraulic system provides the essential power for the lower roller's up-down movement. Operating at a rated pressure of 16Mpa, the main oil cylinder ensures optimal performance. Accurate sensors meticulously track the up-down distance, seamlessly displaying it on an LCD. The hydraulic system's customizable pressure setting guarantees precise hydraulic power to meet the specified rolling force with utmost efficiency.

side roller apparatus
The side roller device is a marvel of engineering, intricately composed of the side roller's main oil cylinder, a self-aligning bearing, and additional high-quality bearings.
Bearing blocks sturdily support the side roller, each side coordinating harmoniously with the frame's guide rail for maximum stability.
Strategically placed within the frame, four oil cylinders drive the side roller bearing block's up-down movement, ensuring pinpoint accuracy. Advanced sensors on the side rollers and frame measure the movement with precision, with results elegantly displayed on an LCD.
For achieving a flawlessly exquisite cone shape, self-aligning bearings are meticulously employed for both side and lower rollers. With the lower roller's level and alignment becoming inclined, fine adjustments allow for a perfect fit between lower and side rollers, introducing a deliberate degree of inclination relative to the horizontal for exceptional results.
3-4, hydraulic drop end
The hydraulic drop end device is a comprehensive system that includes oil cylinders, joints, bearing blocks, and more, all engineered with precision.
The hydraulic drop end system facilitates seamless and effortless product removal along the Roller shaft, streamlining operations.
Upon completing a hydraulic drop closure or opening, the oil cylinder's stroke marvelously resets to zero, ensuring readiness for the next operation.The power source is derived from a steadfast and reliable hydraulic station, ensuring consistent performance.
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, meticulously assembled from a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines to ensure flawless operation.
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.
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 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.
The speed loop artfully manages frame descent, reset operations, and speed calibrations with precision, through the adept use of the throttle valve.
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.
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.
The industrial control PLC meticulously inspects the lower position and both ends of the side roller, guaranteeing synchronization precision of an impressive ±0.15mm.
The state-of-the-art programmable display provides comprehensive real-time visibility of the lower roller and side roller end positions,
and these parameters can be effortlessly configured and set to suit precise requirements.
With an extraordinary displacement transducer resolution of 0.10mm, the display precision reaches an impressive ±0.10mm.
