3.1 Detailed Structural OverviewComprehensive Structure Overview
The fundamental components of our machine tool encompass the frame, upper and lower rollers, side rollers, flipping bearing housing, main drive, hydraulic system, electrical system, lubrication system, and base.
The left and right frames are securely mounted on a unified base, forming the machine's core structure. The upper roller's bearing housing on the left side is integrated into the flipping bearing housing, while the right side's bearing housing is housed within the right frame.
The upper roller acts as the main driving force in the machine, seamlessly connected to the hydraulic motor via a state-of-the-art planetary gearbox. In this advanced configuration, the upper roller stays fixed in position, solely engaging in rotational motion. On the other hand, the working roller exhibits a dual dynamic range: rotational movement coupled with vertical lifting and lowering actions, ensuring precision and efficiency.
The oil cylinders dedicated to the lower and side rollers are expertly installed within the guide grooves of the left and right frames. This sophisticated setup allows for the seamless up-and-down movement and tilting of the rollers, crucial for rolling conical workpieces and ensuring the precise rounding and correction of the workpieces. A pivoting bearing housing on the left frame, operated by a dedicated flipping oil cylinder, facilitates interaction with the upper roller's head. Additionally, the tail of the upper roller features a balancing device that optimally lifts and balances the upper roller when both the upper roller and the tilting frame are open. For impeccable guidance, the working roller's motion relies on top-tier linear slide rails.
Centralized control of the machine is seamlessly integrated into the main operating console, ensuring user-friendly operations and efficiency.
3.1.1 Work rollers
The work rollers are pivotal to the rolling machine's functionality; their quality and performance are directly tied to the machine's lifespan and the precision of rolling operations.
(1)Roller materials
Crafted from high-strength rolling steel, the working rollers undergo an array of meticulous processes including forging, tempering, quenching, stress relief, and precision lathe machining. This rigorous process ensures that the rollers boast exceptional surface contact strength, avoiding any surface impressions during steel plate rolling. These processes make the rollers adept for prolonged use, maintaining their superb mechanical performance. Post rough processing, they undergo tempering treatment achieving a hardness of HB240~300. Precision processing is followed by intermediate frequency quenching to attain hardness levels of HRC45-55, in line with JB/ZG4289-86 rolling steel standards. The stiffness is maintained within (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 is driven by the upper roller (as shown in the diagram below): the upper roller serves as the driving roller, independently powered by a hydraulic motor directly coupled to a high-power planetary gearbox (linear coupling), without intermediate gear transmission. This is the most energy-efficient driving method. The hydraulic motor is equipped with an instant brake, ensuring accurate cessation of roller rotation in the pre-bending state.

between the upper and lower rollers can be pre-set to effectively prevent
This effectively prevents overpressure indentation on soft materials.
The clamping force is controlled 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 supported by two high-quality roller bearings manufactured by Wafangdian, a renowned brand in China. These premium bearings ensure optimal performance and reliability.
Each roller in the four-roller machine is equipped with highly durable self-aligning roller bearings, industry-recommended for their superior performance. These bearings effectively counteract the pressure from shaft misalignment during roller shaft rotation. This design ensures each shaft moves freely and flexibly, minimizing the risk of scratches and cracks on the rollers. The internal configuration of these self-aligning bearings allows them to endure roller shaft misalignment and tilt. Under fixed outer cover forces, this adaptive mobility prevents damage to the roller shaft from reverse forces.
The advantages of these bearings are numerous. Regardless of the roller shaft's deviation, it can smoothly and safely move along the shaft's inclination and return to its original position. Conical rolling demands more stringent criteria, necessitating the roller shaft's ability to tilt, which imposes an unbalanced load on the shaft. This pressure is managed by self-aligning bearings, directing the load into an axial mode. This effectively controls the impact of folding, ensuring smooth and safe self-rotation. Our company implements two self-aligning bearings per roller shaft, utilizing permanent lubrication technology for a lifetime devoid of frequent lubrication needs.
3.2.1Racks and bases
The frame and seat of the coiler produced in the factory are crafted from high-quality domestic Q235A/Q345 steel, CNC machine-cut,
polished and welded,
then sent to a specialized heat treatment facility for stress relief annealing and CNC lathe machining. All workpieces are meticulously documented in the quality tracking system.
3.3.1Hydraulic system
The machine system is designed with an independent hydraulic circuit, featuring two main functions. One segment serves as the main drive, powering the upper and lower working rollers. The auxiliary drive facilitates the lifting and lowering of the lower and side working rollers and powers the tilting frame. Each hydraulic circuit is independently supplied by a high-pressure oil pump driven by an electric motor. The system adopts a superimposed valve structure, offering the following benefits:
Reducing device and installation space
No special installation skills required, enabling quick and easy expansion or modification of the hydraulic system.
Eliminating the diverter valve synchronous system, which is prone to inconsistent pressure impacts between two cylinders,
Overcoming leakage, vibration, and noise issues during pipeline connections, thus enhancing hydraulic system reliability;
The use of stacked components facilitates convenient maintenance and inspection.
Each hydraulic circuit is controlled by two relief valves to regulate pressure. The maximum set pressure for each circuit is 20MPa, primarily governing the main cylinder. Another relief valve is set at 16MPa, mainly controlling the tilting cylinder and balancing cylinder.
In each hydraulic circuit, the main cylinder features two sets of stacked components to adjust its movement speed, accommodating different working speeds for the 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 and right frames and the tilting frame. Pressure sensors and a microcomputer control system monitor and adjust the main cylinder pistons' displacement, meeting synchronization accuracy requirements at both ends of the working roller.

Moreover, the hydraulic station is independently positioned away from the machine base and heat sources, ensuring easy upkeep and maintenance.
d,Our system adheres strictly to national and industry standards. The pipe bending radius is expertly crafted to be no less than 90°, with smooth transitions and strategically placed shock-absorbing clamps. This precision engineering ensures that the hydraulic pipeline remains free from impact and vibration, enhancing system reliability.
