Technical Field
[0001] This application relates to the field of pipeline pricing technology, and in particular to a high-precision manufacturing equipment for curved metal pipelines. Background Technology
[0002] The published patent document CN219233617U discloses a high-precision cold bending device for large-diameter arc-shaped pipes, relating to the field of pipe bending technology. It includes a conveying platform and a bending platform connected in series. Two sets of limiting conveying components are correspondingly arranged on one side of the metal pipe on the platform panel of the bending platform, and a set of pushing bending components is correspondingly arranged on the other side of the metal pipe on the platform panel of the bending platform. The two sets of limiting conveying components are arranged on the same straight line, and the pushing bending component is located on the perpendicular bisector of the line connecting the positions of the two sets of limiting conveying components. This utility model has a simple structure, and its manufacturing process and operation method are simple and easy to implement. It adopts a three-point bending processing technology of "two-point fixing and one-point pushing," resulting in high processing accuracy of the arc-shaped pipe and controllable arc angle. It can directly bend a full-length straight pipe section into an arc shape without pipe cutting, shortening the construction cycle, improving the appearance quality, eliminating off-site transportation, simplifying operation, reducing personnel input, lowering labor costs, and increasing construction efficiency.
[0003] The above devices cannot limit the movement of pipes of different diameters during pipeline transportation, which is not conducive to maintaining the stability and consistency of the pipeline during subsequent bending operations, thus the processing accuracy needs to be further improved. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a high-precision manufacturing equipment for curved metal pipes, which overcomes the deficiencies of existing technologies. It aims to solve the problem that the above devices cannot limit the movement of pipes of different diameters during pipe transportation, which is not conducive to maintaining the stability and consistency of the pipes during subsequent bending operations, thus requiring further improvement in processing accuracy.
[0005] To achieve the above objectives, this application provides the following technical solution: a high-precision manufacturing equipment for arc-shaped metal pipes, comprising several sets of supports, an operating table fixedly mounted on the top of each support, several sets of rotating rollers rotatably connected inside the operating table, a transmission mechanism connecting the sets of rotating rollers, a first horizontal plate fixedly mounted between two sets of operating tables, a double-headed motor fixedly mounted on the top of the first horizontal plate, screws fixedly mounted on both output ends of the double-headed motor, and adjusting blocks threadedly connected to the outer surfaces of both sets of screws. A connecting block is fixedly installed at the top of the adjusting block, a second horizontal plate is fixedly installed at the top of the connecting block, a plurality of group rods are fixedly installed at the top of the second horizontal plate, a collar is fixedly installed at the top of each group of group rods, and the collar is sleeved with the rotating roller. A first C-shaped block is fixedly installed at the top of the collar, and a first rotating shaft is rotatably connected to the open end of the first C-shaped block. A bending mechanism is provided on one side of the plurality of group rotating rollers on the top surface of the operating table, and a limit mechanism is provided on the opposite side of the bending mechanism on the top surface of the operating table.
[0006] By adopting the above technical solution, the pipe is transported to the bending mechanism by rotating rollers for processing. Before processing, according to the different pipe diameters, a double-headed motor is started to drive two sets of screws to rotate simultaneously. The screws drive the adjusting blocks to move closer or further apart through threaded connections, thereby driving the two sets of horizontal plates to move closer or further apart. This causes the two sets of collars to move closer or further apart on the outer ring of the rotating rollers, thereby adjusting the distance between several pairs of opposing first C-shaped blocks. This clamps the metal pipes on the two sets of first rotating shafts. When the transmission mechanism drives several sets of rotating rollers to transport the metal pipes, the first rotating shaft is rotated because it is connected to the first C-shaped blocks. This rotation of the first rotating shaft during the transport of the metal pipes can limit the movement of metal pipes of different diameters, which helps to maintain the stability and consistency of the pipes during the bending operation and improves processing accuracy.
[0007] As a preferred technical solution of this application, the bending mechanism includes a fixed frame, a hydraulic rod is fixedly mounted on one side of the fixed frame, a second C-shaped block is fixedly mounted on the telescopic end of the hydraulic rod, a second rotating shaft is rotatably connected to the open end of the second C-shaped block, a control console is fixedly mounted on the top surface of the operating table located on the fixed frame, and the control end of the hydraulic rod is electrically connected to the control console.
[0008] By adopting the above technical solution, and by pre-setting the control console, the control console controls the extension and retraction of the hydraulic rod to make the second rotating shaft bend the metal pipe, thereby achieving precise bending of the metal pipe and forming the required arc structure.
[0009] As a preferred embodiment of this application, the diameter of the inner ring of the collar is larger than the diameter of the outer ring of the rotating roller.
[0010] By adopting the above technical solution, the diameter of the outer ring of the rotating roller is determined by the diameter of the inner ring of the collar, which helps to prevent the collar from contacting the rotating roller, thereby avoiding the impact of the rotating roller on the collar during rotation and improving its practicality in use.
[0011] As a preferred technical solution of this application, the limiting mechanism includes two sets of upright plates. An electric push rod is fixedly installed on one side of the upright plate. A third C-shaped block is fixedly installed on the telescopic end of the electric push rod. A third rotating shaft is fixedly installed on the top end of the third C-shaped block. The open end of the third C-shaped block is rotatably connected to a [missing information], and the top end is fixedly installed with the output end of the third rotating shaft.
[0012] By adopting the above technical solution, the telescopic movement of the electric push rod drives the third rotating shaft to restrict the position of the metal pipe during the processing, while simultaneously driving the third C-shaped block to rotate and transport the pipe, thereby ensuring the stability and accuracy of the metal pipe during the processing, which is conducive to improving processing precision and yield.
[0013] As a preferred technical solution of this application, the top end of each collar is provided with a guide mechanism, the guide mechanism includes a connector, the connector is fixedly installed on one side of an adjacent first C-shaped block, a guide rod is fixedly installed on one side of the connector, and several sets of fixing blocks are fixedly installed on both sides of the top end of the operating table located on the rotating roller, one end of the guide rod passes through an adjacent set of fixing blocks, and the guide rod is slidably connected to the fixing blocks.
[0014] By adopting the above technical solution, the first C-shaped block pushes the guide rod to slide within the fixed block during its movement, providing guidance for the movement of the first C-shaped block and further ensuring the limiting effect on the metal pipe during transportation.
[0015] As a preferred technical solution of this application, the transmission mechanism includes a motor frame, which is fixedly installed on one side of the operating table. A motor is fixedly installed on the top of the motor frame. The output end of the motor passes through the side wall of the operating table and is fixedly connected to a group of rotating rollers. The rotating ends of the several groups of rotating rollers are connected to a transmission belt.
[0016] By adopting the above technical solution, the rotating rollers are driven by a motor, and the rotating ends of several sets of rotating rollers are connected to a transmission belt. The transmission belt drives several sets of rotating rollers to rotate synchronously, which helps to create holes in the metal pipe and facilitates the smooth transmission of metal pipe materials.
[0017] As a preferred technical solution of this application, a sensor is fixedly installed on the side wall of the first C-shaped block above the first rotating shaft, and a controller is fixedly installed on the top of the first horizontal plate on one side of the dual-head motor. The controller is signal-connected to the sensor and electrically connected to the control terminal of the dual-head motor.
[0018] By adopting the above technical solution, the position of the metal pipe is monitored by the sensor. When the sensor detects that the position of the metal pipe is consistent with the preset value, the controller adjusts the working state of the dual-head motor according to the feedback signal of the sensor. This is conducive to realizing the automated control and intelligent monitoring of the equipment, thereby further improving the processing accuracy of the pipe.
[0019] The beneficial effects of this application are:
[0020] The pipes are transported to the bending mechanism by rotating rollers. Before processing, depending on the pipe diameter, a dual-head motor drives two sets of screws to rotate simultaneously. The screws, through threaded connections, move the adjusting blocks closer or further apart, thereby moving the two sets of horizontal plates closer or further apart. This causes the two sets of collars to move closer or further apart on the outer ring of the rotating rollers, thus adjusting the distance between several pairs of opposing first C-shaped blocks. This clamps the metal pipes on the two sets of first rotating shafts. When the transmission mechanism drives several sets of rotating rollers to transport the metal pipes, the first rotating shaft is rotated because it is connected to the first C-shaped blocks. This rotation of the first rotating shaft during the transport of the metal pipes allows for limiting the movement of metal pipes of different diameters. This helps maintain the stability and consistency of the pipes during bending operations and improves processing accuracy.
[0021] By presetting the control console, the console controls the extension and retraction of the hydraulic rod to cause the second rotating shaft to bend the metal pipe, achieving precise bending of the metal pipe and forming the required arc structure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Reference Figure 1-3 A high-precision manufacturing equipment for arc-shaped metal pipes includes several sets of supports 1. An operating platform 2 is fixedly installed on the top of each support 1. Several sets of rotating rollers 4 are rotatably connected inside the operating platform 2. A transmission mechanism 3 connects the sets of rotating rollers 4. A first horizontal plate 5 is fixedly installed between two sets of operating platforms 2. A double-headed motor 601 is fixedly installed on the top of the first horizontal plate 5. Screws 602 are fixedly installed on both output ends of the double-headed motor 601. Adjusting blocks 603 are threadedly connected to the outer surfaces of both sets of screws 602. A connecting block 8 is fixedly installed on the top of each adjusting block 603. A second horizontal plate 9 is fixedly installed at the top of block 8. Several sets of rods 10 are fixedly installed at the top of the second horizontal plate 9. A collar 11 is fixedly installed at the top of each set of rods 10, and the collar 11 is sleeved with the rotating roller 4. A first C-shaped block 12 is fixedly installed at the top of the collar 11. A first rotating shaft 13 is rotatably connected to the open end of the first C-shaped block 12. A bending mechanism 14 is provided on the top surface of the operating table 2 on one side of the several sets of rotating rollers 4. A limit mechanism 15 is provided on the top surface of the operating table 2 opposite to the bending mechanism 14. The diameter of the inner ring of the collar 11 is larger than the diameter of the outer ring of the rotating roller 4.
[0028] The pipe is transported to the bending mechanism 14 by the rotating roller 4 for processing. Before processing, according to the pipe diameter, the double-headed motor 601 is started to drive two sets of screws 602 to rotate simultaneously. The screws 602 drive the adjusting blocks 603 to move closer or further away through threaded connection, thereby driving the two sets of second horizontal plates 9 to move closer or further away, so that the two sets of collars 11 are closer or further away on the outer ring of the rotating roller 4, thereby adjusting the distance between several sets of opposite first C-shaped blocks 12, so that the metal pipes of the two sets of first rotating shafts 13 are clamped. The transmission mechanism 3 drives several sets of rotating rollers. 4. When conveying metal pipes by rotation, the first rotating shaft 13 is rotatably connected to the first C-shaped block 12. When conveying metal pipes, the first rotating shaft 13 is driven to rotate, which can limit the movement when conveying metal pipes of different diameters. This is beneficial to maintaining the stability and consistency of the pipes during bending operations and improving processing accuracy. The diameter of the inner ring of the collar 11 is used to rotate the outer ring of the roller 4, which helps to prevent the collar 11 from contacting the roller 4. This avoids the roller 4 from affecting the collar 11 during rotation and improves its practicality.

A second C-shaped block 1404 is fixedly mounted on the telescopic end of the hydraulic rod 1403. A second rotating shaft 1405 is rotatably connected to the open end of the second C-shaped block 1404. A control console 16 is fixedly mounted on the top surface of the operating table 2, which is located on the fixed frame 1401. The control end of the hydraulic rod 1403 is electrically connected to the control console 16. The limiting mechanism 15 includes two sets of upright plates 1501.

A third rotating shaft 1504 is fixedly mounted on the top end of the third C-shaped block 1503. A 1505 is rotatably connected to the open end of the third C-shaped block 1503, and the top end of the 1505 is fixedly mounted to the output end of the third rotating shaft 1504.
[0030] By presetting the control console 16, the control console 16 controls the extension and retraction of the hydraulic rod 1403 to cause the second rotating shaft 1405 to perform a bending operation on the metal pipe, thereby achieving precise bending of the metal pipe and forming the required arc structure. The extension and retraction of the electric push rod 1502 drives the third rotating shaft 1504 to restrict the position of the metal pipe during the processing. At the same time, 1505 drives the third C-shaped block 1503 to rotate and transport the pipe, thereby ensuring the stability and accuracy of the metal pipe during the processing, which is conducive to improving processing accuracy and yield.
[0031] Reference Figure 1-3Each collar 11 has a guide mechanism 17 at its top end. The guide mechanism 17 includes a connector 1701, which is fixedly installed on one side of an adjacent first C-shaped block 12. A guide rod 1702 is fixedly installed on one side of the connector 1701. Several sets of fixing blocks 1703 are fixedly installed on both sides of the top of the operating table 2, located on the rotating roller 4. One end of the guide rod 1702 passes through an adjacent set of fixing blocks 1703, and the guide rod 1702 is slidably connected to the fixing block 1703. A sensor is fixedly installed on the side wall of the first C-shaped block 12 above the first rotating shaft 13. A control sensor is fixedly installed on the top of the first horizontal plate 5, located on one side of the dual-head motor 601. The device 18 and controller 18 are connected to the sensor signal and electrically connected to the control terminal of the dual-head motor 601. During the movement of the first C-shaped block 12, the guide rod 1702 is pushed to slide within the fixed block 1703, providing guidance for the movement of the first C-shaped block 12 and further ensuring the limiting effect on the metal pipe during transportation. The position of the metal pipe is monitored by the sensor. When the sensor detects that the position of the metal pipe is consistent with the preset value, the controller 18 adjusts the working state of the dual-head motor 601 according to the feedback signal of the sensor. This is conducive to realizing the automated control and intelligent monitoring of the equipment, thereby further improving the processing accuracy of the pipe.
[0032] Reference Figure 1-3 The transmission mechanism 3 includes a motor frame 301, which is fixedly installed on one side of the operating table 2. A motor 302 is fixedly installed on the top of the motor frame 301. The output end of the motor 302 passes through the side wall of the operating table 2 and is fixedly connected to a set of rotating rollers 4. The rotating ends of the sets of rotating rollers 4 are connected to a transmission belt. The rotating rollers 4 are driven to rotate by the motor 302, and the rotating ends of the sets of rotating rollers 4 are connected to a transmission belt. The transmission belt drives the sets of rotating rollers 4 to rotate synchronously, which makes the metal pipe hollow and facilitates the smooth transmission of metal pipe materials.
[0033] Working principle: The rotating roller 4 drives the pipe to the bending mechanism 14 for processing. Before processing, according to the pipe diameter, the double-head motor 601 drives two sets of screws 602 to rotate simultaneously. The screws 602 drive the adjusting blocks 603 to move closer or further away through threaded connection, thereby driving the two sets of second horizontal plates 9 to move closer or further away, so that the two sets of collars 11 are closer or further away on the outer ring of the rotating roller 4, thereby adjusting the distance between several sets of opposite first C-shaped blocks 12, so that the metal pipes of the two sets of first rotating shafts 13 are clamped. The transmission mechanism 3 drives several sets of When the rotating roller 4 rotates to transport the metal pipe, the first rotating shaft 13 is rotatably connected to the first C-shaped block 12. The first rotating shaft 13 is driven to rotate when transporting the metal pipe, which can limit the movement when transporting metal pipes of different diameters. This is beneficial to maintaining the stability and consistency of the pipe during the bending operation and improving the processing accuracy. By presetting the control console 16, the control console 16 controls the extension and retraction of the hydraulic rod 1403 to make the second rotating shaft 1405 perform the bending operation on the metal pipe, realizing the precise bending of the metal pipe and forming the required arc structure.
[0034] The diameter of the inner ring of the collar 11 is used to rotate the outer ring of the roller 4, which helps to prevent the collar 11 from contacting the roller 4, thus avoiding the impact of the roller 4 on the collar 11 during rotation and improving its practicality. The telescopic movement of the electric push rod 1502 drives the third rotating shaft 1504 to restrict the position of the metal pipe during processing. At the same time, 1505 drives the third C-shaped block 1503 to rotate and transport the pipe, thereby ensuring the stability and accuracy of the metal pipe during processing and improving processing precision and yield.
[0035] Meanwhile, as the first C-shaped block 12 moves, it pushes the guide rod 1702 to slide within the fixed block 1703, providing guidance for the movement of the first C-shaped block 12 and further ensuring the limiting effect on the metal pipe during transportation; the rotating roller 4 is driven to rotate by the motor 302, and the rotating ends of several sets of rotating rollers 4 are connected to the transmission belt, which drives several sets of rotating rollers 4 to rotate synchronously, creating a hole in the metal pipe, which is conducive to the stable transmission of metal pipe materials;
[0036] In addition, by monitoring the position of the metal pipe through the sensor, when the sensor detects that the position of the metal pipe is consistent with the preset value, the controller 18 adjusts the working state of the dual-head motor 601 according to the feedback signal of the sensor, which is conducive to realizing the automated control and intelligent monitoring of the equipment, thereby further improving the processing accuracy of the pipe.
