Top roller and driving assembly, a symphony of engineering
The Top roller device is a masterclass in design, comprising the top roller, a hydraulic drop end, a fixed bearing, a powerful hydraulic motor, and bearing.
The top roller seamlessly transfers torque via the connected hydraulic motor, setting rotation into motion. Ensuring durability, a protective steel bushing is elegantly fitted with the hydraulic drop end.
movement. This careful design ensures the hydraulic drop end is equipped with a protective steel bushing for maximum efficiency.
Lower roller and position inspection unit, a blend of precision and control
Experience the precision of the lower roller device, made up of the lower roller, a robust oil cylinder, lower roller bearing, and a self-aligning bearing.
Each meticulously crafted sliding bearing block supports the lower roller, aligning with the frame guide rail, mounted on two powerful oil cylinders. The hydraulic system provides seamless up-down movement power for the lower roller, with the main oil cylinder operating at 16Mpa. Advanced sensors track the up-down distance, displaying results on an LCD, ensuring the hydraulic system's adjustable pressure delivers the perfect rolling force.

Side roller apparatus, where art meets engineering
Explore the intricate composition of the side roller device, featuring the main oil cylinder, self-aligning bearing, and an array of other precision bearings.
Bearing blocks bolster the side roller, each harmonizing seamlessly with the frame's guide rail for a perfect synergy.
The side roller bearing block's movement is precisely driven by four strategically positioned oil cylinders, ensuring flawless operation, with sensors capturing movement for display on an LCD.
Achieve the perfect cone shape with self-aligning bearings for both side and lower rollers. Masterful fine adjustments ensure a flawless fit between lower and side rollers, introducing a strategic inclination relative to the horizontal axis.
3-4, Hydraulic drop end, the epitome of efficiency
The hydraulic drop end device is a marvel in itself, featuring oil cylinders, expertly crafted joints, bearing blocks, and more.
The hydraulic drop end system seamlessly facilitates the effortless removal of products along the roller shaft, enhancing operational efficiency.
Upon the closure or opening of the hydraulic drop, the oil cylinder's stroke is intuitively reset to zero, ensuring perfection in every operation.The powerhouse driving this efficiency is a dependable hydraulic station, providing unwavering support.
Balance device, the unsung hero of precision
Crafted with meticulous precision, our balance device showcases an avant-garde compact design that promises exceptional performance. When the tipping rack glides off the bearing surface of the top roller, initiating a seamless tipping motion, the device, ingeniously placed on the fixed side, maintains perfect equilibrium. This strategic positioning establishes an intentional distance from the fixed frame, securely held in place by robust screws, ensuring unmatched stability and operational efficiency.

Hydraulic System
Immerse yourself in the prowess of our cutting-edge hydraulic system, which is meticulously curated from a high-precision gear pump, an advanced valve group, and auxiliary pipelines, all engineered for flawless operational excellence.
Our hydraulic valve boasts the Yuken superposition series, revolutionizing the pipeline layoutto be
astonishingly simple, minimizing leakage and streamlining maintenance to deliver superior efficiency like never before.
The system's architecture features three distinct loops: the pressure adjusting loop, synchronization loop, and speed loop, each intricately contributing to a synergistic and harmonious operation.
The pressure adjusting loop deftly modulates the system’s working pressure through the main overflow valve, achieving a formidable working pressure of 16Mpa.
The synchronization loop meticulously calibrates the synchronized movement of the lower roller using a flow divider and throttle valve, empowering precise speed adjustments.
The speed loop masterfully orchestrates frame descent, reset operations, and speed adjustments through the throttle valve, ensuring smooth control and operation.
Electric Control System
Our electric control system is a marvel of modern engineering, featuring an integrated electric cabinet, a sophisticated operation control table, and a portable button box, all operating at 380V/50Hz. Equipped with robust short circuit and overload protection for the main motor, it employs an AC contactor to manage positive and reverse rotations effectively. Utilizing the latest PLC programmable control technology, the system minimizes relay usage for enhanced stability and longevity. Strategically placed buttons and indicator lights on the control table provide a streamlined rolling process, overseeing every operational detail with unparalleled precision.
CNC System
Our NC system is crafted with a rotational encoder and a high-reliability industrial controller, establishing a consistent and dependable control system that you can rely on.
CNC Function
CThis sophisticated NC system offers real-time monitoring, seamless data transmission, and reliable power-off memory throughout the entire rolling process, ensuring optimum performance.
The industrial control PLC automatically inspects the lower position and both ends of the side roller, maintaining an impressive synchronization precision of ±0.15mm.
Our programmable display provides real-time visibility of the lower roller and side roller end positions,
and these critical parameters can be easily configured and set for operational ease.
With a displacement transducer resolution of 0.10mm, the display boasts an impressive precision of ±0.10mm, ensuring reliable performance and accuracy.
