Description

Technical Field

[0001] This invention relates to the field of sheet metal rolling technology, and more specifically, to a vertical sheet metal rolling machine. Background Technology

[0002] Traditional horizontal plate rolling machines face numerous challenges when processing large-diameter, thin-walled workpieces. Because the plate is fed horizontally, its own weight creates a continuous sag during bending, leading to unstable control of the plate's curvature. This is especially problematic when rolling large rings, where the plate head is prone to significant downward bending. This sag effect makes it difficult to achieve the required roundness of the rolled rings, resulting in a significant increase in roundness deviation. This not only affects the overall geometric accuracy of the rings but also severely interferes with the quality of subsequent welding processes and the dimensional matching of the assembly process, thus restricting the large-scale production and application of large-size rings. Simultaneously, during the rolling process, impurities and scale adhering to the steel plate surface are easily detached due to roller friction. These detached materials repeatedly scrape the surface of the plate and the work rolls during operation, causing permanent scratches. When rolling is performed at high temperatures, scale is more easily pressed into the contact area between the plate and the work rolls, further aggravating surface damage, leading to a decrease in the quality of the finished steel plate and an increased scrap rate. Summary of the Invention

[0003] The problem this invention addresses is: how to improve the curling quality of sheet materials.

[0004] To address the aforementioned problems, the present invention provides a vertical plate rolling machine, comprising a main working roller and two auxiliary working rollers arranged vertically, as well as auxiliary support rollers. The two auxiliary working rollers are located on the same side of the main working roller. The area between the roller surface of the main working roller and the roller surfaces of the two auxiliary working rollers is a plate rolling area. The auxiliary support rollers are located on at least one side of the plate rolling area along the moving direction of the plate and are used to support the portion of the plate outside the plate rolling area.

[0005] Optionally, the vertical plate rolling machine further includes a frame, the bottom end of the main working roller is rotatably connected to the frame, and the two auxiliary working rollers are movably disposed on the frame in a direction away from the main working roller.

[0006] Optionally, the vertical plate rolling machine further includes a drive hydraulic cylinder, two guide rails, and a bearing housing assembly corresponding to each shaft end of each of the auxiliary work rollers. Each guide rail is connected to the frame and located on the side of the auxiliary work roller away from the main work roller. The guide rails extend away from the main work roller, and the shaft end is located between the two guide rails. The bearing housing assembly is slidably engaged with the two guide rails. The shaft end of the auxiliary work roller is rotatably mounted on the bearing housing assembly. The drive hydraulic cylinder is connected to the frame and is used to drive the bearing housing assembly to slide along the guide rails.

[0007] Optionally, the bearing housing assembly includes a first bearing housing rotatably connected to the shaft end of the auxiliary work roller, a second bearing housing, and a slide plate. The slide plate is slidably connected to the guide rail. The slide plate is rotatably connected to the first bearing housing and the second bearing housing respectively. The second bearing housing is located at the end of the first bearing housing near the drive hydraulic cylinder and is connected to the drive end of the drive hydraulic cylinder. The second bearing housing rotates about the axis rotatably connected to the slide plate and slides in cooperation with the first bearing housing.

[0008] Optionally, the vertical plate rolling machine further includes a flip cover, which is located above the main working roll and the auxiliary working roll. One end of the flip cover is rotatably connected to the frame, and the flip cover has a working position and a non-working position in the rotation direction of the flip cover. In the working position, the flip cover is connected to the top bearing seat of the main working roll, and in the non-working position, the flip cover is flipped to the side of the auxiliary working roll away from the main working roll.

[0009] Optionally, the vertical plate rolling machine further includes a tilting hydraulic cylinder, the fixed end of which is hinged to the frame, and the movable end of which is hinged to the flip cover, and is used to drive the flip cover to rotate to the working position or the non-working position.

[0010] Optionally, the auxiliary idler includes an idler body and a vertical telescopic bracket. The fixed end of the vertical telescopic bracket is connected to the frame, and the movable end of the vertical telescopic bracket is rotatably connected to the idler body. The roller surface of the idler body is used for rolling engagement with the lower end of the plate.

[0011] Optionally, the auxiliary roller is movably disposed on the frame along the moving direction of the plate.

[0012] Optionally, the vertical telescopic bracket includes an elastic telescopic member connected between the fixed end and the movable end.

[0013] Optionally, the vertical plate rolling machine also includes a control system that is communicatively connected to the drive hydraulic cylinder.

[0014] Compared with related technologies, the vertical plate rolling machine of the present invention uses two auxiliary working rollers located on the same side of the main working roller, with the area between the roller surface of the main working roller and the roller surfaces of the two auxiliary working rollers forming the plate rolling area. This allows the plate to be rolled vertically, effectively eliminating the negative impact of the plate's own weight on the bending curvature, thereby improving the roundness of the rolled ring and the accuracy of subsequent welding and assembly. Furthermore, auxiliary support rollers are located on one side of the plate rolling area along the plate's movement direction, supporting the portion of the plate outside the rolling area. This ensures the plate maintains a stable posture throughout the rolling process, preventing sagging of the free end due to excessive length or thinness of the plate. It also reduces oxide scale accumulation and friction during rolling, protecting the surface quality of the plate and the working rollers, thus improving product quality. Attached Figure Description

Detailed Implementation

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] In the attached figures, the X-axis represents left and right positions, with the positive direction of the X-axis representing the right side and the negative direction representing the left side; the Y-axis represents front and back positions, with the positive direction of the Y-axis representing the front and the negative direction representing the back; and the Z-axis represents up and down positions, with the positive direction of the Z-axis representing the top and the negative direction representing the bottom.

[0019] It should be noted that the terms "first," "second," etc., used in the specification and claims of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0020] Combination Figure 1 As shown, an embodiment of the present invention provides a vertical plate rolling machine, including a main working roller 1 and two auxiliary working rollers 2 arranged vertically, and an auxiliary support roller 3. The two auxiliary working rollers 2 are located on the same side of the main working roller 1. The area between the roller surface of the main working roller 1 and the roller surface of the two auxiliary working rollers 2 is the plate rolling area. The auxiliary support roller 3 is located on at least one side of the plate rolling area along the moving direction of the plate and is used to support the part of the plate outside the plate rolling area.

[0021] Specifically, the main working roller 1 can be understood as the core roller that applies the main bending force to the plate during the rolling process. It is arranged vertically and can rotate to drive the plate to be rolled. In this embodiment, the main working roller 1 can be configured to have a fixed vertical rotation axis and be driven to rotate by a hydraulic motor. For example, the forward and reverse rotation of the main working roller 1 can be achieved by the forward and reverse rotation of the motor to realize the forward and backward movement of the plate. The motor is equipped with a brake so that the working roller can be accurately stopped rotating during the rolling process to ensure accurate positioning of the plate.

[0022] Specifically, two auxiliary work rollers 2 can be installed on one side of the main work roller 1, such as... Figure 1 As shown, two auxiliary work rollers 2 are mounted on the side of the main work roller 1 facing the positive Y-axis and can rotate via their respective bearings. For example, the auxiliary work rollers 2 can be simply fixed to a support structure, and their positions can be adjusted before rolling to accommodate the rolling requirements of sheets of different diameters. Figure 1 As shown, the main working roll 1 and the two auxiliary working rolls 2 can form an open three-point bending structure. The area between the roll surface of the main working roll 1 and the roll surfaces of the two auxiliary working rolls 2 is the plate curling area. When the plate passes through this area, the main working roll 1 and the two auxiliary working rolls 2 jointly apply bending force to the plate, and it gradually bends and takes shape under the squeezing and friction of the rolls.

[0023] Specifically, the auxiliary roller 3 can be configured as one or more independent rollers installed on the sheet material feed or discharge path to provide support as the sheet material enters or leaves the curling area. For example, as Figure 1 As shown, the auxiliary roller 3 can be fixed at a preset height and position.

[0024] Therefore, in this embodiment, two auxiliary working rollers 2 are located on the same side of the main working roller 1, and the area between the roller surface of the main working roller 1 and the roller surfaces of the two auxiliary working rollers 2 is the plate curling area. This allows the plate to be curled vertically, effectively eliminating the negative impact of the plate's own weight on the bending arc, thereby improving the roundness of the rolled ring and the subsequent welding and assembly accuracy. An auxiliary support roller 3 is located on one side of the plate curling area along the plate's movement direction and supports the portion of the plate outside the curling area. This ensures that the plate maintains a stable posture throughout the rolling process, preventing sagging of the free end due to excessive length or thinness of the plate. It also reduces the accumulation and friction of oxide scale during rolling, protecting the surface quality of the plate and the working rollers, thus improving product quality.

[0025] Optionally, combined Figure 1 As shown, the vertical plate rolling machine also includes a frame 4, the bottom end of the main working roller 1 is rotatably connected to the frame 4, and two auxiliary working rollers 2 are movably arranged on the frame 4 in a direction away from the main working roller 1.

[0026] Specifically, the frame 4 is made of high-strength steel as the welding material. During the welding process, a symmetrical welding process is adopted, and welding is carried out step by step from the middle to both ends to reduce welding deformation. After welding, aging treatment is performed to eliminate welding stress and ensure the strength and rigidity of the frame.

[0027] Specifically, the lower journal of the main working roller 1 is supported by a bearing seat mounted on the frame 4, allowing it to rotate freely; or, the bottom of the main working roller 1 is connected to a rotary drive mechanism integrated on the frame 4 via a flange, thereby enabling its rotation function.

[0028] Specifically, the direction away from the main work roller 1 can be understood as the positive Y-axis. The support structure of the auxiliary work roller 2 is installed in the pre-set guide rail or slide on the frame 4, and is driven by hydraulic cylinders, lead screw and nut mechanisms, gear and rack mechanisms or chain transmission mechanisms, etc., so that it can move smoothly on the guide rail or slide in the direction away from or close to the main work roller 1.

[0029] Thus, by rotatably connecting the bottom of the main work roll 1 to the frame 4, a stable reference for the rolling process is established. Two auxiliary work rolls 2 are designed to move along the direction of the main work roll 1 on the frame 4, allowing the gap in the sheet metal rolling area to be flexibly adjusted according to the sheet metal thickness, material, and required rolling radius. Operators can precisely adjust the distance between the auxiliary work rolls 2 and the main work roll 1 according to the specific requirements of the workpiece, thereby achieving fine control over the bending torque applied to the sheet metal and the forming accuracy. This significantly improves the versatility and processing flexibility of the equipment, ensures the rolling quality of sheets of different sizes and thicknesses, and avoids problems such as large roundness deviations caused by improper work roll positioning, which affect the accuracy of subsequent welding and assembly.

[0030] Optionally, combined Figure 1 As shown, the vertical plate rolling machine also includes a drive hydraulic cylinder 5, two guide rails 6, and a bearing housing assembly 7, which are provided corresponding to each shaft end of each auxiliary working roller 2. Each guide rail 6 is connected to the frame 4 and is located on the side of the auxiliary working roller 2 away from the main working roller 1. The guide rail 6 extends in a direction away from the main working roller 1, and the shaft end is located between the two guide rails 6. The bearing housing assembly 7 is slidably engaged with the two guide rails 6. The shaft end of the auxiliary working roller 2 is rotatably mounted on the bearing housing assembly 7. The drive hydraulic cylinder 5 is connected to the frame 4 and is used to drive the bearing housing assembly 7 to slide along the guide rail 6.

[0031] Specifically, each shaft end of each auxiliary work roller 2 is equipped with a driving hydraulic cylinder 5, two guide rails 6, and a bearing housing assembly 7. The bearing housing assembly 7 refers to the bearing housing equipped with a bearing, the inner ring of which mates with the shaft end of the auxiliary work roller 2. The two guide rails 6 are mounted on the frame 4 and extend away from the main work roller 1. Each shaft end of the auxiliary work roller 2 is located between the two guide rails 6. The bearing housing of the bearing housing assembly 7 is in sliding engagement with the two guide rails 6. The driving hydraulic cylinder 5 drives the bearing housing assembly 7 to slide back and forth between the two guide rails 6, so as to move the auxiliary work roller 2 away from or closer to the main work roller 1.

[0032] Thus, by setting two guide rails 6 on the frame 4 extending away from the main work roller 1, a highly rigid and precise linear trajectory is provided for the movement of the auxiliary work roller 2. Through the sliding engagement of the bearing housing assembly 7 with the two guide rails 6 and the rotatable shaft end of the auxiliary work roller 2, the auxiliary work roller 2 can be precisely guided and supported when subjected to enormous rolling pressure, effectively limiting its skewing or wobbling during movement. By driving the hydraulic cylinder 5 to connect with the frame 4 and drive the bearing housing assembly 7 to slide along the guide rails 6, precise and stable adjustment of the position of the auxiliary work roller 2 is achieved, thereby accurately controlling the rolling radius of the sheet material, improving the rolling quality of the sheet material and the reliability of equipment operation.

[0033] Optionally, combined Figure 1and Figure 2 As shown, the bearing housing assembly 7 includes a first bearing housing 71 rotatably connected to the shaft end of the auxiliary working roller 2, a second bearing housing 72, and a slide plate 73. The slide plate 73 is slidably connected to the guide rail 6. The slide plate 73 is rotatably connected to the first bearing housing 71 and the second bearing housing 72 respectively. The second bearing housing 72 is located at the end of the first bearing housing 71 near the drive hydraulic cylinder 5 and is connected to the drive end of the drive hydraulic cylinder 5. The second bearing housing 72 rotates around the axis rotatably connected to the slide plate 73 and slides in cooperation with the first bearing housing 71.

[0034] Specifically, the inner ring of the first bearing housing 71 mates with the shaft end of the auxiliary work roller 2. The first bearing housing 71 and the second bearing housing 72 are arranged laterally along the Y-axis and connected as a whole by the slide plate 73. The first bearing housing 71 and the second bearing housing 72 can rotate relative to the slide plate 73 respectively. The second bearing housing 72 is located at the end of the first bearing housing 71 near the drive hydraulic cylinder 5 and is connected to the drive end of the drive hydraulic cylinder 5. That is, when the auxiliary work roller 2 needs to be moved, the driving force of the drive hydraulic cylinder 5 acts on the first bearing housing 71 and the slide plate 73 through the second bearing housing 72. The stroke position of the auxiliary work roller 2 is controlled by the displacement sensor built into the drive hydraulic cylinder 5. At the same time, the drive hydraulic cylinder 5 adopts a high-pressure sealing structure, which can withstand the hydraulic pressure under heavy loads and avoid hydraulic leakage. In addition, it is controlled by a proportional servo valve to realize stepless speed regulation of the lateral movement of the auxiliary work roller, thereby improving the stability of the winding process.

[0035] like Figure 2 As shown, with Figure 2 The bearing housing assembly 7 above the auxiliary working roller 2 is described as follows: When the axis of the auxiliary working roller 2 is in a vertical state, the first bearing housing 71 and the second bearing housing 72 do not rotate relative to each other, and the driving hydraulic cylinder 5 can drive the first bearing housing 71, the second bearing housing 72 and the slide plate 73 to move along the guide rail 6. When the shaft end below the auxiliary work roller 2 approaches the main work roller 1 relative to the shaft end above it, the first bearing seat 71 deflects counterclockwise relative to the second bearing seat 72. This situation applies at least to the following working conditions: During the strip coiling process, the main work roller 1 remains vertical. If the thickness of the strip below is greater than the thickness of the strip above, it means that the straight distance between the lower end of the auxiliary work roller 2 and the main work roller 1 is greater than the straight distance between its upper end and the main work roller 1. At this time, the lower drive hydraulic cylinder 5 extends. Since the first bearing seat 71 above the auxiliary work roller 2 is rotatably connected to the slide plate 73, when the lower drive hydraulic cylinder 5 extends, the upper first bearing seat 71 rotates counterclockwise relative to the second bearing seat 72. It can also be understood that the second bearing seat 72 rotates clockwise relative to the first bearing seat 71.

[0036] Thus, by using the slide plate 73 as a sliding carrier that directly contacts the guide rail 6, and by rotatably connecting it to the first bearing seat 71 and the second bearing seat 72 respectively, and by slidingly engaging the second bearing seat 72 with the first bearing seat 71 around the axis of its rotatable connection with the slide plate 73, the bearing seat assembly 7 can ensure smooth operation even when the upper and lower driving hydraulic cylinders 5 are not synchronized when driven by the driving force of the driving hydraulic cylinder 5, avoiding jamming. This significantly improves the self-adaptive capability of the bearing seat assembly 7, thereby ensuring that the auxiliary working roller 2 can move smoothly and steadily along the guide rail 6. This effectively solves the problem of easy jamming of traditional rigid bearing seats under complex working conditions, thereby improving the reliability and rolling accuracy of the vertical plate rolling machine.

[0037] Optionally, combined Figure 1 As shown, the vertical plate rolling machine also includes a flip cover 8, which is located above the main working roller 1 and the auxiliary working roller 2. One end of the flip cover 8 is rotatably connected to the frame 4. In the rotation direction of the flip cover 8, the flip cover 8 has a working position and a non-working position. In the working position, the flip cover 8 is connected to the top bearing seat of the main working roller 1. In the non-working position, the flip cover 8 flips to the side of the auxiliary working roller 2 away from the main working roller 1.

[0038] Specifically, the flip cover 8 is located above the area where the sheet metal is curled, and the end of the flip cover 8 located in the positive direction of the Y-axis is rotatably connected to the top of the frame 4. The working position of the flip cover 8 refers to the position of the flip cover 8 as follows: Figure 1 In the horizontal position shown, at the working position, the lower surface of the flip cover 8 can be provided with a support structure that precisely matches the top bearing seat of the main working roller 1. When the flip cover 8 is in the working position, the connection is achieved by gravity or pre-tightening force.

[0039] The non-working position of the flip cover 8 refers to the position after the flip cover 8 is tilted upward relative to the frame 4. In this embodiment, the working position refers to the unloading process, and the non-working position refers to the loading process. During loading, the flip cover 8 is flipped to the non-working position to facilitate the hoisting and positioning of the sheet metal. During rolling, the flip cover 8 is flipped to the working position, and the sheet metal rolling area, the flip cover 8, and the frame 4 form a sealed working space to ensure stable rolling of the sheet metal. During unloading, it is flipped to the non-working position again to facilitate the removal of the finished product and improve operational convenience.

[0040] Thus, at the working position, the flip cover 8, connected to the top bearing seat of the main working roll 1, not only effectively covers the space above the main working roll 1 and the auxiliary working roll 2, preventing debris from entering the roll system and extending the equipment's service life, but more importantly, its connection with the top bearing seat of the main working roll 1 significantly enhances the structural rigidity and stability of the main working roll 1 during the winding process, thereby improving winding accuracy and product quality. Simultaneously, by flipping the flip cover 8 to the side of the auxiliary working roll 2 away from the main working roll 1 in the non-working position, when equipment maintenance, cleaning, or sheet replacement is required, the flip cover 8 can be easily flipped to the non-working position, providing operators with a spacious and unobstructed working space, greatly improving equipment maintenance efficiency and operational convenience.

[0041] Optionally, combined Figure 1 As shown, the vertical plate rolling machine also includes a tilting hydraulic cylinder 9. The fixed end of the tilting hydraulic cylinder 9 is hinged to the frame 4, and the movable end of the tilting hydraulic cylinder 9 is hinged to the flip cover 8, and is used to drive the flip cover 8 to rotate to the working position or the non-working position.

[0042] Specifically, the cylinder body of the tilting hydraulic cylinder 9 is rotatably connected to the top of the bracket 4, and the hydraulic rod of the tilting hydraulic cylinder 9 is rotatably connected to the flip cover 8. The tilting hydraulic cylinder 9 can extend and retract under the control of the control system.

[0043] Thus, the rotating connection structure between the tilting hydraulic cylinder 9 and the frame 4 provides a stable power support point for the tilting motion of the cover 8, enabling the cover 8 to smoothly reciprocate between the working and non-working positions. Driving the cover 8 to rotate via the tilting hydraulic cylinder 9 ensures precise alignment between the cover 8 and the top bearing seat of the main working roller 1 when in the working position, thereby guaranteeing structural stability during the plate rolling process. When it is necessary to change the plate material or switch to a non-working state, the tilting hydraulic cylinder 9 quickly tilts the cover 8 to the side of the auxiliary working roller 2, simplifying the operation process and replacing manual labor with power drive, significantly improving the automation level and operational safety of the equipment.

[0044] Optionally, combined Figure 1 As shown, the auxiliary roller 3 includes a roller body 31 and a vertical telescopic bracket 32. The fixed end of the vertical telescopic bracket 32 ​​is connected to the frame 4, and the movable end of the vertical telescopic bracket 32 ​​is rotatably connected to the roller body 31. The roller surface of the roller body 31 is used to roll and cooperate with the lower end of the plate.

[0045] Specifically, the idler roller body 31 can be a solid steel roller or a rubber-coated roller. The vertical telescopic bracket 32 ​​is used to adjust the height of the idler roller body 31, and it can be implemented in various forms. For example, it can be a screw-nut transmission mechanism, where a motor drives the screw to rotate, causing the nut and connecting parts to move up and down. The fixed end of the vertical telescopic bracket 32 ​​is connected to the frame 4, and the journals at both ends of the idler roller body 31 are mounted on supports at the movable end via bearings. The roller surface of the idler roller body 31 is used for rolling contact with the lower end of the sheet material. When the roller surface of the idler roller body 31 contacts the lower end of the sheet material, the rotation or passive rotation of the idler roller body 31 ensures a smooth transition of the sheet material, preventing scratches or jamming on the sheet material surface.

[0046] Thus, when the board enters the curling area, the vertical telescopic support 32 adjusts the rise or fall of the roller body 31 according to the actual height and curling state of the board, ensuring that its roller surface always maintains a rolling engagement with the lower end of the board. This allows the auxiliary roller 3 to accurately support the portion of the board outside the curling area, ensuring that the board always receives stable and appropriate support. This avoids offset, sagging, or deformation caused by mismatched support heights, thereby guaranteeing the geometric accuracy of the board during the curling process and improving the roundness of the final product. At the same time, the rolling engagement between the roller surface of the roller body 31 and the lower end of the board effectively reduces friction and minimizes the risk of scratches on the board surface.

[0047] Optionally, combined Figure 1 As shown, the auxiliary roller 3 is mounted on the frame 4 and moves along the direction of the plate's movement.

[0048] Specifically, a slide rail can be installed on the frame 4. The fixed end of the vertical telescopic support 32 slides with the slide rail through a slider or roller, and the auxiliary roller 3 moves and is positioned along the slide rail through a drive device, such as a screw and nut mechanism, a gear and rack mechanism or a hydraulic cylinder.

[0049] Thus, by moving the auxiliary roller 3 along the direction of material movement on the frame 4, the auxiliary roller 3 can flexibly match the feeding path of the material. Therefore, when rolling materials of different specifications, by adjusting the position of the auxiliary roller 3 on the frame 4, it can be ensured that the roller is always at the optimal support point for the material, effectively addressing the problem of sagging or shifting of the material due to its own weight outside the rolling area. Simultaneously, the auxiliary roller 3 also includes a roller body 31 and a vertical telescopic bracket 32, which further enhances the adaptability and support accuracy of the material, ensuring consistent posture of the material before and after entering the rolling area, thereby guaranteeing the roundness and processing quality of the final formed ring.

[0050] Optionally, the vertical telescopic bracket 32 ​​includes an elastic telescopic member connected between the fixed end and the movable end.

[0051] Specifically, the elastic telescopic component can be implemented in various forms. For example, it can be a spring structure, such as a helical compression spring, a disc spring, or a torsion bar spring. These springs absorb or release energy through their own elastic deformation, thereby providing a variable and elastic connection between the fixed end and the movable end of the vertical telescopic support 32. When the plate undergoes a small displacement under force, the spring can compress or extend accordingly to maintain stable support for the roller body 31. In addition, the elastic telescopic component can also be a hydraulic or pneumatic buffer device, such as a hydraulic cylinder or air cylinder with an accumulator. When the pressure exerted by the plate on the roller body 31 changes, the hydraulic or pneumatic device can achieve flexible extension and contraction of the vertical telescopic support 32 through fluid flow and the action of the accumulator, thereby smoothly supporting the plate.

[0052] Thus, by introducing an elastic telescopic component into the vertical telescopic bracket 32 ​​of the auxiliary roller 3, the roller body 31 can make slight displacement adjustments according to the real-time stress state of the sheet material. This effectively absorbs the vibration energy generated by the sheet material during movement, reducing surface scratches or localized stress concentration caused by rigid support. Simultaneously, the elastic telescopic component balances the supporting force through its own deformation, ensuring a stable support state for the sheet material outside the curling area even when the sheet material thickness is uneven or the curling radius changes. This improves the smoothness of the rolling process and guarantees the roundness and surface quality of the final formed workpiece.

[0053] Optionally, the vertical plate rolling machine also includes a control system that is communicatively connected to the drive hydraulic cylinder 5.

[0054] Specifically, the control system can monitor the actual position of the auxiliary work roll 2 in real time (e.g., through feedback from a displacement sensor) according to preset rolling process parameters, and accurately calculate and output control commands to the drive hydraulic cylinder 5 based on the deviation between the actual position and the target position. After receiving the command, the drive hydraulic cylinder 5 accurately drives the bearing housing assembly 7 to slide along the guide rail 6, thereby adjusting the position of the auxiliary work roll 2.

[0055] This overcomes the limitations of manual operation in terms of response speed and control precision, effectively solving the problem that operators cannot accurately control the hydraulic cylinder movements in real time, leading to limited displacement accuracy of the auxiliary working roller 2 and consequently affecting the quality and consistency of the sheet metal rolling process. Simultaneously, the control system ensures that the two auxiliary working rollers 2 maintain coordinated operation with the main working roller 1 throughout the rolling process, precisely adjusting the geometry of the sheet metal rolling area, thereby effectively improving the roundness and processing accuracy of the rolled sheet metal. Especially when processing large-diameter, thin-walled workpieces, this automated control method effectively avoids the problems of downward bending of the plate head and difficulty in ensuring roundness when rolling large-specification ring parts using traditional horizontal plate rolling machines. It also reduces reliance on operator experience, ensuring process consistency across different batches of workpieces during the rolling process, providing reliable technical support for achieving high-precision, high-efficiency vertical plate rolling operations.

[0056] In some embodiments, the control system also includes a hydraulic system and an electrical system. The hydraulic system is divided into a main drive and an auxiliary drive. The main drive uses two motors to drive a high-pressure pump to supply oil, providing rotational power for the main work roll 1. The auxiliary drive uses two motors to drive a high-pressure pump with a rated pressure of 31.5 MPa, providing power for the movement of the auxiliary work roll 2 and the rotation of the flip cover 8. The hydraulic system is equipped with an oil tank, a high-precision filter, and a cooler to ensure the cleanliness of the hydraulic oil and control the operating temperature between 30-50°C. The electrical system uses a Siemens PLC as the control core and an industrial computer as the main operating interface. It has both automatic and manual control systems, which can be switched via a touchscreen or buttons. It integrates a fault diagnosis and display function, which can monitor parameters such as hydraulic system pressure, motor speed, and work roll position in real time, and promptly report fault information. The intelligent learning function can record the rolling parameters of different sheet materials and automatically optimize the control logic. The real-time display accuracy of the work roll position is ±0.1 mm. The power-off memory function can save the current operating parameters and rolling progress. Safety protection functions include overload protection, emergency stop protection, and limit protection.

[0057] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
