3.1Overview of the structure
The fundamental structure of the JSYZSK1 CNC Machine Tool includes various critical sections: frame, upper roller, lower roller, side roller, flipping bearing housing, main drive, hydraulics, electrics, lubrication, and base. Mounted on a unified base, the left and right frames form the machine's core. The upper roller's bearing housing is ingeniously integrated, with the left end inserted into the flipping bearing housing and the right end securely installed within the right frame.
The robust structure of the machine tool comprises the left and right frames mounted on a unified base, forming the machine's primary framework. The upper roller's left bearing housing is embedded in the flipping bearing housing, while its right bearing housing is firmly positioned within the right frame.
The upper roller is the main driving force of the machine, seamlessly connected to the hydraulic motor through a state-of-the-art planetary gearbox. This setup ensures the upper roller remains fixed in position, executing only rotational movements. In contrast, the working roller performs both rotational and vertical motions, enabling efficient lifting and lowering tasks.
The oil cylinders for the lower and side rollers are strategically installed in the guide grooves of the left and right frames. Through reciprocating motion, these cylinders facilitate the vertical and tilting movements of the rollers, allowing for precise rolling of conical workpieces and effective correction and rounding. Additionally, a flipping bearing housing on the left frame, operated by a flipping oil cylinder, enables seamless interaction with the head of the upper roller. A balancing device at the tail of the upper roller ensures it remains balanced and elevated when the upper roller and tilting frame are open. The working roller's movement is meticulously guided by premium linear slide rails.
The machine's control is centralized on a sophisticated main operating console, ensuring seamless and intuitive operation.
3.1.1Work rollers
As one of the most vital components of a rolling machine, the quality and performance of the work rollers significantly influence the machine's lifespan and overall rolling precision.
(1)Roller materials
Crafted from high-strength rolling steel, the working rollers undergo rigorous processes including forging, tempering, quenching, stress relief, and precision lathe machining. These procedures ensure the rollers achieve optimal surface contact strength, preventing any surface impressions during steel plate rolling. This meticulous craftsmanship guarantees the rollers' durability and comprehensive mechanical performance. After rough processing, the rollers are tempered to a hardness of HB240~300, followed by intermediate frequency quenching to achieve a hardness of HRC45-55. Complying with the JB/ZG4289-86 standard for rolling steel, the rollers exhibit a stiffness within (1/700-1/1000) L, where L represents the distance between the centerlines of the two side frames.

300, and after precision processing, they undergo intermediate frequency quenching with a hardness of HRC45-55. In accordance with the JB/ZG4289-86 standard for rolling steel, the stiffness complies with (1/7001/1000) L, where L refers to the distance between the centerlines of the two side frames.
(2) The rotation of the work roller: the hydraulic motor is connected to the planetary gearbox, and then the torque is transmitted to the work roller.
The four-roller rolling machine is driven by the upper roller, as illustrated in the diagram below. The upper roller, acting as the driving roller, is independently powered by a hydraulic motor directly coupled to a high-power planetary gearbox via a linear coupling, eliminating the need for intermediate gear transmission. This advanced setup is the most energy-efficient driving method available. The hydraulic motor features an instant brake for precise cessation of roller rotation during the pre-bending phase.

This effectively prevents overpressure indentation on soft materials.
The clamping force is expertly managed by the relief valve of the hydraulic station.
3.1.2Bearings at both ends of the work rollers
Each end of all working rollers is equipped with two premium roller bearings, sourced from Wafangdian shafts, a renowned brand in China. These bearings enhance the overall performance and reliability of the machine.
Each roller in the four-roller machine is equipped with industry-recommended, high-durability self-aligning roller bearings. These bearings effectively counteract the pressure from shaft misalignment during roller rotation. Their exceptional freedom and flexibility prevent scratches and cracks on the rollers. The internal design allows them to endure misalignment and tilt, while their foldable mobility under fixed outer cover forces protects the roller shaft from reverse force damage.
The advantages of these bearings are profound. No matter the deviation, the roller shaft can smoothly and safely realign itself, returning to its original position. Conical rolling demands stringent requirements, necessitating the roller shaft's ability to tilt under an unbalanced load, which pressures the bearings significantly. Self-aligning bearings channel this load into an axial mode, effectively mitigating folding impacts and enabling smooth, safe self-rotation. Our company utilizes two self-aligning bearings per roller shaft, employing 'permanent lubrication technology' for the product's entire lifespan, eliminating the need for frequent lubrication.

3.3.1Hydraulic system
The machine system boasts an independent hydraulic circuit with two main functions. One part powers the upper and lower working rollers, serving as the main drive section. The other part aids in the lifting and lowering of the lower and side rollers and powers the tilting frame flipping. Each circuit is independently powered by a high-pressure oil pump driven by an electric motor. The system's superimposed valve structure offers:
Space-efficient design and installation
Quick and easy installation and expansion without special skills for the hydraulic system.
Elimination of diverter valve synchronous system issues, ensuring consistent pressure between cylinders,
Reduction of leakage, vibration, and noise in pipeline connections, enhancing hydraulic system reliability;
Convenient maintenance and inspection due to stacked components.
Each hydraulic circuit is regulated by two relief valves to control pressure. The maximum set pressure is 20MPa for the main cylinder and 16MPa for the tilting and balancing cylinders.
In each hydraulic circuit, the main cylinder features two sets of stacked components to adjust movement speed, accommodating different working speeds for side and lower rollers under various conditions.
To ensure synchronization accuracy of the main cylinders at both ends of each moving working roller, high-precision displacement sensors are installed on the left, right, and tilting frames. These sensors, along with pressure sensors and a microcomputer control system, monitor and adjust the main cylinder pistons' displacement, achieving synchronization accuracy requirements.
