Description

Technical Field

[0001] This utility model relates to the field of roll rounding technology, and in particular to an automatic rounding device for a steel plate roll rolling machine. Background Technology

[0002] Plate rolling machines are essential equipment in industrial manufacturing for bending steel plates, widely used in the production of pressure vessels, storage tanks, pipelines, and various cylindrical steel components. With the diversification of steel plate specifications and the increasing demands for processing precision, traditional plate rolling machines not only need to adapt to steel plates of different thicknesses and diameters, but also need to ensure uniform stress distribution and the final roundness accuracy during the rolling process. Therefore, higher demands are placed on the efficiency, flexibility, and precision of steel plate rolling processes, making the automation and adjustability of plate rolling machines a key research and development focus.

[0003] Existing steel plate rolling machines typically employ a fixed drive roller and driven roller structure. The drive roller is driven by a motor, and friction is used to move the steel plate and gradually shape it. The driven roller generally serves as an auxiliary support and limiter, and the fixed spacing between the rollers is adjusted to accommodate steel plates of different thicknesses or diameters. However, the roller spacing adjustment in existing equipment often relies on mechanical screws or manual disassembly, resulting in a limited adjustment range and low precision. During the rolling process, the force on the steel plate is mainly concentrated at a few contact points, easily leading to uneven force distribution or misalignment, and making it difficult to monitor and adjust the roundness of the steel plate in real time.

[0004] The adjustment method of the roller spacing of the automatic rounding device of the steel plate rolling machine is usually fixed or relies on manual adjustment, which makes it difficult to quickly adapt to the processing needs of various specifications of steel plates and has poor flexibility. During the rolling process, the roundness of the steel plate cannot be monitored in real time, which leads to limited processing accuracy and the steel plate is prone to deviation or uneven stress. Therefore, an automatic rounding device for the steel plate rolling machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic rounding device for steel plate rolling machines, which aims to improve the problem that the adjustment method of the roller spacing of the automatic rounding device for steel plate rolling machines in the prior art is usually fixed or relies on manual adjustment, making it difficult to quickly adapt to the processing needs of steel plates of various specifications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic rounding device for a steel plate rolling machine, comprising a frame, wherein a mounting plate one and a mounting plate two are equidistantly arranged on the top of the frame, the outer side of the mounting plate two is connected to a connecting plate by multiple hinges, and the mounting plate two and the connecting plate are connected by a snap-fit ​​assembly, two active rollers are rotatably connected between the mounting plate one and the mounting plate two, a power assembly is provided on the outer side of the mounting plate one, and a waist-shaped hole is opened on the outer side of both the mounting plate one and the connecting plate, a U-shaped block slides inside the waist-shaped hole, and a lead screw one and a lead screw two are rotatably connected to the top of the U-shaped block respectively, and a handle is provided on the top of the lead screw two;

[0007] As a further description of the above technical solution: a fixing frame is provided on the top of the mounting plate one, a motor two is provided on the top of the fixing frame, a bevel gear one is provided at the output end of the motor two, a rotating cylinder is rotatably connected to the top of the fixing frame, the rotating cylinder is connected to the bevel gear two, and the lead screw one is meshed with the bevel gear two.

[0008] As a further description of the above technical solution: the U-shaped block on the left is provided with a positioning cylinder and a bearing respectively. The inner sides of the positioning cylinder and the bearing are provided with long grooves at equal intervals. Long blocks are respectively engaged in the long grooves. The long grooves and long blocks are connected by pins. The long blocks are arranged at equal intervals on the outer side of the rotating shaft. A driven roller is arranged on the outer side of the rotating shaft, and the driven roller is arranged between the U-shaped blocks.

[0009] As a further description of the above technical solution: the power assembly includes a motor, which is located on the top of the frame. A gear is provided at the output end of the motor. A gear is provided at the end of each drive roller near the motor, and the gears are meshed with the gears.

[0010] As a further description of the above technical solution: the buckle assembly includes a U-shaped plate, a pull rod is slidably mounted on the outer side of the U-shaped plate, a limit ring is provided on the outer side of the pull rod, and a spring is provided between the limit ring and the inner side of the U-shaped plate.

[0011] As a further description of the above technical solution: the inner side of the mounting plate is provided with slide rails equidistantly, and electric sliders slidably on the outside of the slide rails. Slide rails are provided between the electric sliders. Electric sliders are provided equidistantly on the outside of the slide rails.

[0012] As a further description of the above technical solution: a steel cylinder is provided between the driving roller and the driven roller, and all the displacement sensors are in contact with the inner wall of the steel cylinder;

[0013] As a further description of the above technical solution: U-shaped plates two are equidistantly arranged on the inner side of the mounting plate one, and each of the U-shaped plates two is rotatably connected to a limit roller.

[0014] This utility model has the following beneficial effects:

[0015] This invention employs a power assembly to drive both the active and driven rollers in a coordinated manner. Through a motor and gear transmission, the active roller achieves stable rotation, while the driven roller, in conjunction with the steel cylinder, serves as a support and rolling correction structure. A displacement sensor monitors the roundness of the steel plate in real time and adjusts the roller position accordingly. This achieves high rolling accuracy, uniform stress distribution, and stable processing. Compared to existing technologies that rely solely on a single active roller, which can easily lead to steel plate misalignment or insufficient rolling accuracy, this invention overcomes the shortcomings of large steel plate misalignment and roundness errors during the rolling process, as well as the inability to adjust in real time.

[0016] This invention employs a combination of lead screw adjustment and a snap-fit ​​assembly. By adjusting lead screw one and lead screw two, precise control of the distance between the driving and driven rollers is achieved, thus adapting to the rolling requirements of steel plates of different specifications. Simultaneously, the snap-fit ​​assembly enables quick connection and disassembly of the mounting plate two and the connecting plate, facilitating rapid replacement or maintenance of the driven roller by operators. This achieves the technical advantages of flexible adjustment, convenient assembly and disassembly, and efficient maintenance. Compared to existing technologies that use fixed roller spacing or complex disassembly structures, this invention overcomes the shortcomings of difficult driven roller replacement, poor adaptability to different steel plate specifications, and low maintenance efficiency.

[0029] U-shaped plates 17 are equidistantly arranged on the inner side of mounting plate 12. Each U-shaped plate 17 is rotatably connected to a limiting roller 18. The U-shaped plates 17 provide a support position for the installation of the limiting roller 18 and limit its range of motion. The limiting roller 18 is prevented from shifting during the steel plate processing.

[0030] Reference Figure 4 The left U-shaped block 21 is equipped with a positioning cylinder 30 and a bearing 33. The positioning cylinder 30 and bearing 33 provide rotational support for the installation of the driven roller 16, ensuring its smooth and flexible movement.

The elongated blocks 36 provide a positioning function for the rotation of the driven roller 16, ensuring the movement stability of the driven roller 16. The elongated grooves 35 and the elongated blocks 36 are connected by pins 32. The design of the pins 32 facilitates quick disassembly and assembly of the components, thereby facilitating maintenance and replacement. The elongated blocks 36 are equidistantly arranged on the outer side of the rotating shaft 34. The driven roller 16 is arranged on the outer side of the rotating shaft 34 and is positioned between the U-shaped blocks 21. The driven roller 16 provides clamping and auxiliary rolling functions for the steel plate, ensuring that the steel plate can be uniformly stressed to complete the processing.

[0031] Working principle: The automatic roundness correction device of this steel plate rolling machine drives the active roller 5 to rotate through the power component to achieve the roundness correction of the steel plate. The power component outputs driving force from motor 2, which drives the meshing gear 4 through gear 3 to rotate, thereby making the active roller 5 rotate synchronously to complete the clamping and rolling of the steel plate. At the same time, the driven roller 16 works in concert with the steel cylinder 11, using the circumferential support and limiting function of the steel cylinder 11 to correct the roundness of the steel plate. The displacement sensor 29 is installed on the outside of the extension rod 28 and contacts the inner wall of the steel cylinder 11 to monitor the roundness change of the steel plate in real time. The feedback data assists in the precise adjustment of the position and pressure during the rolling process.

[0032] Screw 10 is driven by motor 7, whose output shaft is connected to bevel gear 8. Bevel gear 8 meshes with bevel gear 9, causing screw 10 to rotate and adjust the height and pressure of the drive roller 5. At the same time, screw 22 is adjusted by the manual handle 23 at the top, allowing U-shaped block 21 to slide within waist-shaped hole 31, changing the distance between drive roller 5 and steel cylinder 11 to adapt to the processing requirements of steel plates of different diameters. The positioning cylinder 30 of U-shaped block 21 is supported by bearing 33 to ensure the smooth rotation of the structure. The inner side of the positioning cylinder 30 is provided with long groove 35, which is connected to long block 36 by pin 32. Long block 36 is evenly distributed on the outer side of rotating shaft 34 to achieve auxiliary positioning function and ensure that the steel plate does not shift during the rolling process. The connection between pin 32 and long block 36 is designed for quick disassembly, which facilitates the replacement of driven roller 16 of different specifications or maintenance and repair when the device malfunctions, greatly improving the applicability and maintenance efficiency of the equipment.

[0033] The buckle assembly consists of a U-shaped plate 13 and a pull rod 15. The pull rod 15 provides a rebound force through a spring 14 to enable quick connection and disassembly of the mounting plate 19 and the connecting plate 20. The application of the buckle assembly ensures the stability of the overall structure of the device during operation and the convenience of disassembly and maintenance. At the same time, it facilitates the removal of the steel cylinder 11.

[0034] A slide rail 24 is installed on the inner side of the mounting plate 12. An electric slider 25 is slidably installed on the slide rail 24. A slide rail 26 is connected between the electric sliders 25. An electric slider 27 is slidably installed on the outside of the slide rail 26. An extension rod 28 is connected to the outside of the electric slider 27. During the rolling process of the steel plate, the position of the extension rod 28 is adjusted by electronic control so that it can dynamically cooperate with the displacement sensor 29 for real-time monitoring, while maintaining the uniform force and positional accuracy of the steel plate throughout the rolling process.

[0035] The limiting roller 18 is rotatably connected to the U-shaped plate 17 inside the mounting plate 12. The limiting roller 18 plays a restraining role during the rolling of the steel plate, preventing the steel plate from shifting laterally due to external forces, and ensuring that the steel plate completes the rolling operation along the designed trajectory. At the same time, the rotating drum 37 installed on the top of the fixed frame 6 is connected to the bevel gear 9, providing stable support and transmission stability for the rotation of the lead screw 10, and preventing it from moving upward with the lead screw 10.
