Introducing the cutting-edge Versatile Precision CNC Roll Forming Machine for Steel Plates, a pinnacle of engineering by Pully Intelligent Equipment Co., Ltd. This state-of-the-art marvel boasts a sophisticated four-roller system, with the top roller as its centerpiece. This component serves as the primary drive, performing precise rotational movements. Meanwhile, the lower roller gracefully moves in a vertical path to expertly guide the plate, ensuring seamless friction alignment lengthwise. The two side rollers elegantly maneuver up and down at an angle, imparting the perfect plastic deformation to the steel plate. With its adjustable side roller, this machine achieves both symmetric and asymmetric bending with finesse, resulting in minimal flat ends. It surpasses traditional three-roller machines by eliminating the need for pre-bending procedures, offering rough leveling and becoming an indispensable tool across industries like petroleum, chemical, boiler manufacturing, shipbuilding, hydroelectricity, metal structures, and machinery.
Machine construction:
The core architecture of this advanced machine includes the upper roller device and driving unit, lower roller device,side roller apparatus,hydraulic drop end system, lubrication unit, robust left and right frames, stable chassis, and more.

Top roller and driving assembly:
The top roller device integrates the top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and bearing, forming a seamless unit.
The top roller's torque is masterfully transferred through a linked hydraulic motor, initiating its rotation with precision. A protective steel bushing is securely fitted with the hydraulic drop end.
The hydraulic drop end also boasts a protective steel bushing for enhanced safeguarding.
Lower roller and position inspection unit:
The lower roller device comprises the lower roller, oil cylinder, lower roller bearing, and a cutting-edge self-aligning bearing.
Every sliding bearing block that supports the lower roller is precisely aligned with the frame guide rail. It is adeptly mounted on dual oil cylinders, with the hydraulic system powering the lower roller's vertical movement. Operating at a rated pressure of 16Mpa, the main oil cylinder is a powerhouse. Advanced sensors meticulously track the up-down distance, displaying it on an LCD for easy monitoring. The hydraulic system's adjustable pressure ensures precise power delivery to achieve the desired rolling force with unmatched accuracy.

Side roller apparatus:
The side roller device is a sophisticated assembly comprising the side roller's main oil cylinder, a self-aligning bearing, and additional bearings.
Every bearing block supports the side roller, with each side harmoniously coordinating with the frame's guide rail for flawless operation.
Driven by four strategically placed oil cylinders within the frame, the side roller bearing block's vertical movement is effortlessly executed. Advanced sensors installed on the side rollers and frame measure the movement, with results displayed on an LCD for optimal accuracy.
To craft an exquisite cone shape, self-aligning bearings are utilized for both side and lower rollers. As the level and alignment of the lower roller become inclined, meticulous adjustments ensure a perfect fit between lower and side rollers, introducing a subtle degree of inclination relative to the horizontal for superior results.
3-4, hydraulic drop end:
The hydraulic drop end device is a refined system composed of oil cylinders, joints, bearing blocks, and additional components.
The hydraulic drop end system enables effortless product removal along the Roller shaft, simplifying the process efficiently.
Upon completing the hydraulic drop closure or opening, the oil cylinder's stroke is automatically reset to zero, ensuring seamless operation and easy maintenance.The reliable hydraulic station serves as the steadfast power source, ensuring consistent performance.
Balance device:
Discover our ingenious, state-of-the-art balance device, meticulously crafted to deliver cutting-edge performance in a compact form. As the tipping rack gracefully disengages from the top roller's bearing face, initiating its tipping movement, this advanced balance device springs into action. Ingeniously designed, as gravity guides the top roller's end downward, this device maintains perfect equilibrium by its strategic placement on the fixed side. Thoughtfully positioned at a meticulously calculated distance from the fixed frame and secured with high-quality screws, it ensures unwavering stability and exceptional operational efficiency.

Hydraulic System
Introducing our cutting-edge hydraulic system, a true masterpiece of engineering excellence. Meticulously assembled from a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, this system guarantees flawless operation.
The hydraulic valve, featuring the acclaimed Yuken superposition series, ingeniously ensures that the pipeline layoutis
incredibly intuitive, significantly reducing leakage and simplifying maintenance for unparalleled efficiency.
This sophisticated system architecture includes three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each meticulously designed to contribute 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 that ensure seamless operation.
The speed loop artfully manages frame descent, reset operations, and speed calibrations with precision, through the adept use of the throttle valve, ensuring flawless performance.
Electric Control System
Our electric control system is a marvel of modern engineering, 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, this system is the epitome of reliability. Harnessing the power of PLC programmable control technology, it boasts minimal relay usage which enhances stability and longevity. With strategically placed buttons and indicator lights on the control table, the rolling process is streamlined and efficiently managed, with every operational aspect precisely monitored.
CNC System
Our NC system is a paragon of reliability, meticulously designed with a rotational encoder and a high-reliability industrial controller to create a steadfast and dependable control mechanism.
CNC Function
CThis advanced NC system offers unparalleled real-time monitoring, effortless data transmission, and reliable power-off memory throughout the entire rolling process, ensuring unmatched efficiency and dependability.
The industrial control PLC meticulously inspects the lower position and both ends of the side roller, guaranteeing synchronization precision of an impressive ±0.15mm for exceptional accuracy.
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, offering unmatched control.
With an extraordinary displacement transducer resolution of 0.10mm, the display precision reaches an impressive ±0.10mm, ensuring supreme accuracy.
