3.1Overview of the structure
The Marine Plate CNC Rolling Machine Tool's robust construction includes key sections like the frame, upper and lower rollers, side rollers, flipping bearing housing, main drive, hydraulics, electronics, lubrication, and base. Mounted on a unified base, the left and right frames constitute the main body. The upper roller's left bearing housing integrates into the flipping bearing housing, while the right bearing housing is securely fixed within the right frame, ensuring stability and precision during operations.
The left and right frames are securely mounted on a unified base, forming the structural backbone of this advanced machine. The left end of the upper roller's bearing housing is ingeniously integrated into the flipping bearing housing, with the right end's bearing housing firmly installed in the right frame, thereby enhancing the overall stability and precision during execution.
The upper roller serves as the primary driving component of the machine, seamlessly linked to the hydraulic motor through an advanced planetary gearbox. In this robust configuration, the upper roller maintains a fixed position, engaging solely in rotational motion. Meanwhile, the working roller excels with both rotational and vertical movements, adeptly performing lifting and lowering actions.
The machine's oil cylinders for the lower and side rollers are precisely installed within the guide grooves of the left and right frames. The cylinders' reciprocating motion allows the lower and side rollers to move seamlessly up and down along these guide grooves and tilt as needed. This dynamic capability facilitates the rolling of conical workpieces and the precise correction and rounding of workpieces. Additionally, a flipping bearing housing on the left frame can be opened and closed by a dedicated flipping oil cylinder. This mechanism interacts efficiently with the upper roller's head. At the upper roller's tail, a balancing device ensures it remains balanced and lifts smoothly when the roller and tilting frame are open. The working roller's motion is meticulously guided by premium linear slide rails.
The machine's control system is centralized on the main operating console, offering intuitive and efficient management of all functions.
3.1.1 Work Rollers
As one of the most vital components of a rolling machine, the quality and performance of work rollers directly determine the machine's lifespan and rolling precision.
(1)Roller Materials
The working rollers are crafted from high-strength rolling steel, undergoing a series of meticulous processes including forging, tempering, quenching, stress relief, and precision lathe machining. Tailored to user requirements, these procedures ensure the rollers achieve high surface contact strength, preventing surface impressions during steel plate rolling. This guarantees the rollers' ability to withstand long-term steel plate rolling while maintaining their comprehensive mechanical performance. After rough processing, they undergo tempering treatment with a hardness rating of HB240~300. Following precision processing, intermediate frequency quenching further enhances their surface hardness to HRC45-55. Complying with the JB/ZG4289-86 rolling steel standard, the stiffness aligns with (1/700-1/1000) L, where L denotes 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 operates with the upper roller as the driving force, independently powered by a hydraulic motor directly coupled to a high-power planetary gearbox via linear coupling-eliminating the need for intermediate gear transmission. This highly efficient driving method optimizes energy use. The hydraulic motor includes an instant brake feature, ensuring precise cessation of roller rotation during the pre-bending phase.

The clamping force regulation is 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 features two premium roller bearings, crafted by Wafangdian shafts-renowned for their superior quality in China.
Each roller in the four-roller machine is equipped with top-tier, highly durable self-aligning roller bearings, as recommended by industry experts. This design effectively mitigates the pressure caused by shaft misalignment during roller rotation. The freedom and flexibility of each shaft prevent the risk of scratches and cracks on the rollers. The internal structure of these self-aligning bearings allows them to endure roller shaft misalignment and tilt. When subjected to fixed outer cover forces, this foldable mobility prevents damage to the roller shaft from reverse forces.
The remarkable advantage of these bearings is their adaptability; regardless of the deviation position of the roller shaft, it can move smoothly and safely along the shaft's inclination, ultimately returning to its original position. The requirements for conical rolling are stringent due to the necessity for the roller shaft to tilt, placing an unbalanced load on it and exerting significant pressure on the bearings. Self-aligning bearings direct this load into an 'axial' mode, effectively controlling the impact of folding and allowing for smooth, safe self-rotation. Our company uses two self-aligning bearings on each roller shaft, augmented with 'permanent lubrication technology' that spans the entire lifespan of the product, eliminating the need for frequent bearing lubrication.
3.2.1Racks and bases
The frame and seat of the coiler produced in the factory are constructed from high-quality domestic Q235A/Q345 steel, which is CNC
machine cut
, polished, and welded, followed by stress relief annealing at a professional heat treatment factory and CNC lathe machining. All workpiece records are meticulously included in the quality tracking system.
3.3.1Hydraulic system
The machine system boasts an independent hydraulic circuit featuring two primary functions. One sector drives the main section, powering the upper and lower working rollers. The other facilitates auxiliary tasks, including lifting and lowering the lower and side working rollers, and flipping the tilting frame. Each hydraulic circuit receives power from a high-pressure oil pump driven by an electric motor. The system's standout feature is its superimposed valve structure, characterized by:
Space-saving design and installation ease
No specialized installation skills required, allowing quick and easy modifications or expansions to the hydraulic system.
Avoidance of diverter valve synchronous systems, which are susceptible to inconsistent pressure impacts between cylinders,
Elimination of leakage, vibration, and noise issues in pipeline connections, thus enhancing the hydraulic system's reliability;
Maintenance convenience due to the use of stacked components.
Each hydraulic circuit is regulated by two relief valves to manage pressure. One valve is set to a maximum pressure of 20MPa, primarily controlling the main cylinder pressure. Another relief valve is set at 16MPa, mainly controlling the pressure of the tilting and balancing cylinders.
Within each hydraulic circuit, the main cylinder comprises two sets of stacked components to adjust the main cylinder's movement speed, accommodating various working speeds for the side and lower rollers under different conditions.
To ensure precise synchronization of the main cylinders at both ends of each moving working roller, high-precision displacement sensors are installed on the left, right frames, and tilting frame. Through pressure sensors and a microcomputer control system, the displacement of the main cylinder pistons is monitored and adjusted, meeting the synchronization accuracy requirements.
