Description

Technical Field

[0001] This utility model relates to the field of steel pipe forming technology, and in particular to an arc-pressure guiding rolling device for steel pipe forming. Background Technology

[0002] In the field of steel pipe processing, arc-pressure guided rolling devices are key equipment used for steel pipe forming, straightening, and conveying. Their performance directly affects the processing accuracy and surface quality of steel pipes. With industrial development, the application scenarios of steel pipes are becoming increasingly diversified, and the requirements for parameters such as pipe diameter and curvature are becoming more complex. Traditional rolling devices are difficult to meet the high adaptability requirements due to structural limitations. Especially in continuous processing, how to achieve stable clamping and efficient conveying has become a technical challenge. A guide rolling device that can adapt to different pipe diameters and take into account both flexibility and stability is needed to improve processing efficiency and reduce equipment adjustment costs.

[0003] In existing technologies, steel pipe rolling devices mostly adopt rigid clamping structures, which use rollers with fixed spacing to press and transport steel pipes. The technical principle relies on the motor to drive the rollers to rotate, and the friction force to move the steel pipe. The clamping force is preset by the mechanical structure and cannot be dynamically adjusted. Although some equipment can manually adjust the roller spacing to adapt to different pipe diameters, the adjustment process depends on manual operation and lacks an elastic buffer mechanism. Such structures can meet the needs when processing single-diameter pipes, but they perform poorly when processing multiple specifications of steel pipes continuously. Uneven clamping force can easily cause scratches on the surface of the steel pipe or slippage during transport.

[0004] The main problem with existing technologies is that rigid clamping structures cannot adapt to changes in pipe diameter, leading to damage to the steel pipe surface or unstable clamping. Because the clamping force is fixed, when the steel pipe diameter deviation is large, excessively tight clamping will squeeze the steel pipe surface to form indentations, while excessively loose clamping will cause conveying deviation or even detachment, seriously affecting processing quality and safety. In addition, frequent adjustments to the clamping structure not only reduce production efficiency but also increase operational complexity, making it difficult to meet the requirements of modern production lines for flexibility and automation. To address these issues, an arc-pressure guided rolling device for steel pipe forming is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an arc-pressure guiding rolling device for steel pipe forming, which aims to improve the problems of steel pipe surface damage and unstable clamping caused by the inability of traditional rigid clamping to adapt to changes in pipe diameter in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an arc-pressure guiding rolling device for steel pipe forming, comprising a device body, a support frame fixedly connected to the top of the device body, a rotating rod rotatably connected inside the support frame, a conveying component provided on the outer wall of the support frame, and an arc-pressure component provided on the top of the device body;

[0007] The conveying assembly includes a lower roller and an upper roller disposed on top of the lower roller. The lower roller is fixedly connected to the outer wall of the rotating rod. Connecting blocks are fixedly connected to both ends of the upper roller. The outer wall of the connecting block is slidably connected to the inside of the support frame. A moving block is fixedly connected to the side wall of the connecting block. The outer wall of the moving block is slidably connected to the inside of the support frame. A moving rod is fixedly connected to the top of the moving block. The outer wall of the moving rod is slidably connected to the inside of the support frame. A spring is sleeved on the outer wall of the moving rod. A motor is fixedly connected to the side wall of the support frame. The output end of the motor is fixedly connected to one end of the rotating rod.

[0008] As a further description of the above technical solution:

[0009] One end of the spring is fixedly connected inside the support frame, and the other end of the spring is fixedly connected to the top of the movable block.

[0010] As a further description of the above technical solution:

[0011] The arc pressure assembly includes a connecting rod and an arc pressure wheel disposed on the outer wall of the connecting rod, the outer wall of the connecting rod being rotatably connected inside the main body of the device.

[0012] As a further description of the above technical solution:

[0013] The connecting rod is slidably connected to a top cover, and the top cover has a locking hole inside. The bottom of the top cover is in contact with the top of the arc pressure wheel.

[0014] As a further description of the above technical solution:

[0015] A fixing block is fixedly connected inside the connecting rod, and a locking block is slidably connected inside the connecting rod, with the locking block engaging with the locking hole.

[0016] As a further description of the above technical solution:

[0017] The side wall of the card block is fixedly connected to a limiting block, and the outer wall of the limiting block is slidably connected inside the connecting rod.

[0018] As a further description of the above technical solution:

[0019] A second spring is provided inside the connecting rod. One end of the second spring is fixedly connected to the side wall of the fixing block, and the other end of the second spring is fixedly connected to the side wall of the limiting block.

[0020] As a further description of the above technical solution:

[0021] A second motor is fixedly connected inside the main body of the device, and the output end of the second motor is fixedly connected to one end of the connecting rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the steel pipe moves forward by rotating the lower roller driven by the motor at the bottom of the upper roller. During this process, the steel pipe squeezes the upper roller, which in turn drives the connecting block and the moving block to squeeze the moving rod and the spring. The spring uses its elasticity to stably clamp the steel pipe, thus achieving adaptive clamping for steel pipes of different diameters. This solves the problem of surface damage and unstable clamping caused by the inability of traditional rigid clamping to adapt to changes in pipe diameter, and improves the versatility of the device and the stability of the steel pipe during transportation.

[0024] 2. In this utility model, by pressing the locking block, it causes the limiting block to move inside the connecting rod, squeezing the second spring, thereby releasing the restriction on the locking hole. At this time, the top cover is pulled upward and removed, and then the arc pressure wheel is pulled to complete the disassembly and replacement. This solves the problem that the traditional arc pressure wheel fixing structure is cumbersome to disassemble, time-consuming and labor-intensive, making it difficult for the equipment to quickly adapt to the processing needs of steel pipes with different curvatures. It significantly improves the flexibility and processing efficiency of the device in the steel pipe processing process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an arc-pressed guide rolling device for steel pipe forming, comprising a device body 1, which supports the overall structure and provides an installation foundation. A support frame 2 is fixedly connected to the top of the device body 1. The support frame 2 is used to install a rotating rod 4, a conveying component, and an arc-pressing component, and to maintain structural stability. The rotating rod 4 is rotatably connected inside the support frame 2. The rotating rod 4 is used to drive the lower roller 3 to rotate, thereby realizing the conveying of the steel pipe. A conveying component is provided on the outer wall of the support frame 2, which is used to drive the steel pipe to move and adaptively adjust the clamping force. An arc-pressing component is provided on the top of the device body 1, which is used to perform arc-pressing forming on the steel pipe.

[0034] The conveying assembly includes a lower roller 3 and an upper roller 6 mounted on top of the lower roller 3. The lower roller 3 is driven by a rotating rod 4, providing the basic power for conveying the steel pipe. The upper roller 6 works in conjunction with the lower roller 3 to clamp the steel pipe and automatically adjusts its position when the pipe diameter changes. The lower roller 3 is internally fixedly connected to the outer wall of the rotating rod 4 to ensure stable power transmission. Connecting blocks 7 are fixedly connected to both ends of the upper roller 6. The connecting blocks 7 connect the upper roller 6 to the moving block 8 and transmit the pressure of the steel pipe to the spring 10. The outer wall of the connecting block 7 is slidably connected to the inside of the support frame 2, allowing the upper roller 6 to move up and down to accommodate different pipe diameters. The moving block 8 is fixedly connected to the side wall of the connecting block 7. The moving block 8 drives the moving rod 9 and compresses the spring 10. The outer wall of the moving block 8 is slidably connected to the inside of the support frame 2 to ensure stable transport. For dynamic stability, a moving rod 9 is fixedly connected to the top of the moving block 8. The moving rod 9 is used to transmit the elastic force of the spring 10, so that the upper roller 6 maintains the clamping force on the steel pipe. The outer wall of the moving rod 9 is slidably connected to the inside of the support frame 2 to ensure accurate movement direction. The outer wall of the moving rod 9 is fitted with a spring 10, which is used to provide elastic clamping force, so that the upper roller 6 adapts to the change of steel pipe diameter. A motor 5 is fixedly connected to the side wall of the support frame 2. The motor 5 is used to drive the rotating rod 4 to rotate, providing power for steel pipe conveying. The output end of the motor 5 is fixedly connected to one end of the rotating rod 4 to ensure efficient power transmission. One end of the spring 10 is fixedly connected to the inside of the support frame 2, and the other end is fixedly connected to the top of the moving block 8, so that the spring 10 can automatically adjust the compression amount according to the change of steel pipe diameter to achieve stable clamping.

[0035] Reference Figures 3-5The arc forming assembly includes a connecting rod 12 and an arc forming wheel 11 disposed on the outer wall of the connecting rod 12. The connecting rod 12 supports and drives the arc forming wheel 11 to rotate. The arc forming wheel 11 applies pressure to the steel pipe to achieve arc forming. The outer wall of the connecting rod 12 is rotatably connected to the inside of the main body 1 of the device, allowing the arc forming wheel 11 to rotate freely. A top cover 13 is slidably connected to the outer wall of the connecting rod 12. The top cover 13 is used to fix the position of the arc forming wheel 11 and facilitate disassembly and replacement. A locking hole 14 is provided inside the top cover 13. The locking hole 14 is used to cooperate with a locking block 16 to lock the top cover 13. The bottom of the top cover 13 contacts the top of the arc forming wheel 11 to ensure that the arc forming wheel 11 remains stable during rotation. A fixing block 15 is fixedly connected inside the connecting rod 12. The fixing block 15 is used to fix one end of the second spring 18 and provide support. A locking block 16 is slidably connected inside the connecting rod 12. The locking block 16 is used to cooperate with the locking hole 14 to lock the top. The cover 13 is quickly locked and unlocked. The locking block 16 and the locking hole 14 engage to ensure that the top cover 13 remains fixed in normal working condition. The side wall of the locking block 16 is fixedly connected to the limiting block 17, which is used to limit the movement range of the locking block 16 and transmit the elastic force of the second spring 18. The outer wall of the limiting block 17 is slidably connected to the inside of the connecting rod 12 to ensure the movement stability of the locking block 16. The connecting rod 12 is provided with the second spring 18, which is used to provide elastic force to keep the locking block 16 engaged with the locking hole 14. One end of the second spring 18 is fixedly connected to the side wall of the fixing block 15, and the other end is fixedly connected to the side wall of the limiting block 17 to ensure effective transmission of elastic force. The main body 1 of the device is fixedly connected to the second motor 19, which is used to drive the connecting rod 12 to rotate and provide power to the arc pressure wheel 11. The output end of the second motor 19 is fixedly connected to one end of the connecting rod 12 to ensure the reliability and efficiency of power transmission.

[0036] Working principle: During the steel pipe conveying process, after the motor 5 starts, it drives the rotating rod 4 to rotate, which in turn drives the lower roller 3 to rotate. The steel pipe is placed between the upper roller 6 and the lower roller 3, and is conveyed forward by friction. When the diameter of the steel pipe changes, the upper roller 6 will float up and down with the change in the diameter of the steel pipe: when the diameter of the steel pipe increases, the steel pipe presses the upper roller 6 upward, causing the connecting block 7 to drive the moving block 8 to slide upward along the inner wall of the support frame 2, while compressing the spring 10. When the diameter of the steel pipe decreases, the restoring force of the spring 10 pushes the moving block 8 downward, so that the upper roller 6 always maintains a moderate clamping force on the steel pipe, avoiding surface damage to the steel pipe that may be caused by rigid clamping, and ensuring stability during the conveying process. The spring 10 can ensure sufficient clamping force. While applying force, excessive pressure is avoided on the steel pipe. During the arc forming stage, motor 2 19 drives the connecting rod 12 to rotate, which in turn drives the arc forming roller 11 to roll and form the steel pipe. When it is necessary to replace the arc forming roller 11 with a different curvature, the operator only needs to press the locking block 16, which causes the limiting block 17 to compress the spring 2 18, releasing the locking block 16 from the locking hole 14. Then the top cover 13 can be removed upwards. At this time, the arc forming roller 11 is no longer fixed and can be removed for replacement. After the replacement is completed, the top cover 13 is reinstalled. Under the restoring force of the spring 2 18, the locking block 16 automatically resets and re-engages with the locking hole 14, completing the quick fixation. This avoids the cumbersome disassembly problem of the traditional bolt fixing method and realizes the adaptability of the equipment to the processing of steel pipes with different curvatures.
