side roller apparatus
The side roller device is meticulously crafted with the side roller's main oil cylinder, self-aligning bearing, and other indispensable bearings.
Bearing blocks provide steadfast support to the side roller, with each side seamlessly coordinating with the frame's guide rail, ensuring optimal functionality.
The up-down movement of the side roller bearing block is driven by four strategically positioned oil cylinders within the frame. Sensors, precisely installed on both the side rollers and frame, meticulously measure movement, which is elegantly displayed on an LCD for effortless monitoring.
To create a beautifully intricate cone shape, self-aligning bearings are strategically used for both side and lower rollers. By adjusting the lower roller's level and alignment to achieve inclination, fine-tuning secures a perfect fit between lower and side rollers, introducing a precise degree of inclination relative to the horizontal plane.
3-4, hydraulic drop end
The hydraulic drop end device includes durable oil cylinders, joints, bearing blocks, and more, ensuring peak efficiency.
The hydraulic drop end system ensures effortless removal of products along the Roller shaft, optimizing operations with ease.
Upon completing hydraulic drop closure or opening, the oil cylinder's stroke is ingeniously reset to zero, maintaining impeccable precision and reliability.Our state-of-the-art hydraulic station serves as the reliable powerhouse for the Precision CNC Bending Machine for Automatic Steel Plate Roll Forming, delivering unwavering and 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, intricate valve group, and premium auxiliary pipelines, ensuring flawless and seamless 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, advanced operation control table, and versatile portable button box, all operating at 380V/50Hz. 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.
