top roller and driving assembly
The Top roller device is a masterful assembly featuring a top roller, a hydraulic drop end, fixed bearing, hydraulic motor, and bearing, all orchestrated in harmony.
The top roller transmits torque effortlessly, thanks to a connected hydraulic motor that facilitates its smooth, fluid rotation. A meticulously fitted protective steel bushing enhances the hydraulic drop end.
movement. This hydraulic drop end is expertly equipped with a protective steel bushing, ensuring seamless and fluid operation.
lower roller and position inspection unit
The lower roller device boasts a precise and optimal design, including a lower roller, oil cylinder, lower roller bearing, and a self-aligning bearing.
Each sliding bearing block, a testament to precision, aligns flawlessly with the frame guide rail to support the lower roller. Mounted on robust oil cylinders, the hydraulic system empowers the lower roller's up-down movement. The primary oil cylinder operates under a rated pressure of 16Mpa. Sophisticated sensors track every up-down distance, rendering data on an LCD. This adjustable hydraulic system guarantees the precise rolling force needed, elevating accuracy to unprecedented heights.

side roller apparatus
This side roller device is a fine example of engineering excellence, crafted with a main oil cylinder, self-aligning bearing, and other pivotal bearings.
Sturdy bearing blocks provide unwavering support, ensuring each side roller seamlessly interacts with the frame's guide rail for optimal performance.
The ingenious up-down movement of the side roller bearing block, driven by four strategically positioned oil cylinders within the frame, is meticulously measured by sensors placed on both side rollers and the frame, with real-time data displayed on an LCD for straightforward monitoring.
To craft an exquisitely precise cone shape, the incorporation of self-aligning bearings for both side and lower rollers is essential. By adjusting the lower roller's level and alignment to an inclined position, a snug fit with the side rollers is achieved, introducing a meticulous degree of inclination relative to the horizontal.
3-4, hydraulic drop end
The hydraulic drop end device stands as a symbol of robust engineering, featuring powerful oil cylinders, joints, bearing blocks, and more, all designed for unmatched efficiency.
The hydraulic drop end system ensures effortless product removal along the Roller shaft, seamlessly streamlining operations for maximum efficiency.
After executing the hydraulic drop closure or opening, the oil cylinder's stroke is adeptly reset to zero, sustaining impeccable precision.The power source is reliably provided by a state-of-the-art hydraulic station, ensuring consistent performance.
Balance Device
Ingeniously crafted to revolutionize balance, our state-of-the-art device boasts a cutting-edge, compact structure that ensures unparalleled performance. When the tipping rack elegantly slips from the bearing face of the top roller and begins its graceful tipping motion, this advanced balance apparatus steps into action. As gravity naturally tugs the top roller's end downward, this expertly designed mechanism maintains perfect equilibrium, strategically positioned on the fixed side. This precise placement, at a meticulously calculated distance from the fixed frame, is securely anchored by premium screws, guaranteeing unwavering stability and exceptional operational efficiency.

Hydraulic System
Our hydraulic system is nothing short of a masterpiece. Meticulously assembled with a high-precision gear pump, an intricate valve group, and premium auxiliary pipelines, it ensures flawless operation.
The hydraulic valve incorporates the renowned Yuken superposition series, ingeniously ensuring that the pipeline layoutis
remarkably intuitive, dramatically reducing leakage and simplifying maintenance, culminating in exceptional efficiency.
This sophisticated architecture boasts three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each meticulously contributing to harmonious and efficient operations.
The pressure adjusting loop skillfully modulates the system’s working pressure via the main overflow valve, achieving a robust pressure of 16Mpa, ensuring consistent performance.
The synchronization loop deftly fine-tunes the synchronized movement of the lower roller through precise flow dividers and throttle valves, allowing impeccable speed adjustments.
The speed loop artfully governs frame descent, reset operations, and speed calibrations with precision, utilizing the adept 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 operating at 380V/50Hz. It is equipped with robust short circuit and overload protection for the main motor, employing an AC contactor for managing both positive and reverse rotations. Through the power of PLC programmable control technology, this system minimizes relay usage, enhancing stability and longevity. Strategically placed buttons and indicator lights on the control table ensure the entire rolling process is streamlined, efficiently managing every operational aspect with precision.
CNC System
The NC system is a paragon of reliability, featuring a rotational encoder and a high-reliability industrial controller, creating a steadfast and dependable control platform.
CNC Function
CThis advanced NC system provides 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 with an impressive ±0.15mm 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 set to meet precise requirements.
