Description

Technical Field

[0001] This utility model specifically relates to the field of adjustable elbow technology, and more specifically to a three-elbow adjustable pipe bending mechanism. Background Technology

[0002] In large pipeline systems in industries such as construction, chemical, petroleum, and power, bends often need to bypass various obstacles, such as building beams and columns, equipment foundations, etc., while also meeting the flow and pressure requirements of different areas. This requires the use of adjustable bend mechanisms to achieve flexible pipeline layout and improve the adaptability and reliability of the pipeline system.

[0003] With the continuous development of automation technology, technical support has been provided for the precise control of the three-bend adjustable pipe bending mechanism. Compared with the traditional pipe bending technology, which can only achieve bending at a single angle or a limited number of angles, it is difficult to meet the diverse needs of complex and ever-changing pipeline systems for bend angles. The three-bend adjustable pipe bending mechanism can effectively adjust according to the needs of production and installation to achieve multi-angle bending of pipelines.

[0004] Traditional elbow structures currently only have one bend and can only bend the pipe in one direction. This bend is relatively simple and cannot effectively adjust the bending angle, resulting in low equipment efficiency. Furthermore, traditional pipe bending mechanisms can only bend one pipe at a time. Therefore, when bending a large number of pipes, traditional bending mechanisms are less efficient than three-bend pipe bending mechanisms. This pipe bending mechanism is equipped with three adjustable elbows, which can bend three pipes simultaneously during operation, greatly improving work efficiency. To facilitate the separation of the pipe and the elbow, this device can also adjust the movable seat, thereby effectively improving the pipe bending efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a three-bend adjustable pipe bending mechanism. In this structure, a first bending structure, a second bending structure, and a third bending structure are installed on the top of the movable frame. The height of the three bending structures is adjusted by the extension and retraction of the connecting rod driven by the corresponding cylinder, thereby effectively allowing the bending structures at different positions to contact the pipe. Then, the worm gear drives the worm wheel installed on the rotating cylinder to rotate. The worm wheel engages with the groove on the connecting rod through the protrusion inside the rotating cylinder, thereby causing the corresponding worm to deflect the corresponding bending structure at a certain angle, thus effectively bending the pipe. In this device, to facilitate the separation of the pipe, the movable frame can also be moved left and right along the base by the lead screw, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A three-bend adjustable pipe bending mechanism includes a movable frame; a first pipe bending structure is fitted onto the top of the movable frame; the first pipe bending structure includes an adjusting seat; two symmetrically arranged pipe bending cylinders are fitted onto the top of the adjusting seat; the bottom of the adjusting seat is fixedly installed with a connecting rod; the connecting rod passes through the rotating cylinder; a groove on the connecting rod engages with a protrusion on the temporal part of the rotating cylinder; a worm gear is fixedly installed on the outside of the rotating cylinder; and both ends of the rotating cylinder are movably installed with mating seats.

[0009] As a further technical solution of this utility model, one end of each of the connecting rods away from the first bend structure, the second bend structure and the third bend structure extends into the U-shaped frame fixedly installed at the bottom of the movable frame, and is connected to the corresponding cylinder rods by couplings respectively.

[0011] As a further technical solution of this utility model, the movable frame has sliders fixedly installed at both ends on one side of the U-shaped frame; the sliders are slidably installed with the slide rails on the base;

[0012] As a further technical solution of this utility model, the base has lead screws movably mounted at both ends via bearings; an L-shaped connecting plate is fitted onto the lead screw; the L-shaped connecting plate is fixedly installed at the bottom of the movable frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In use, the conveyor belt above the pipe end to be bent is moved left and right along the base by a screw rod, so that the first, second and third pipe bending structures are moved to the bottom of the corresponding pipe. Then, the pipe bending cylinder in the pipe bending structure is moved upward by a cylinder, so that the displacement corresponds to both sides of the pipe. Finally, the adjustment seat is rotated by the meshing between the worm gear and the worm, so as to effectively achieve the pipe bending effect.

[0016] 2. In this utility model, when adjusting the movable frame, the drive motor on the side plate is connected to the second pulley at one end of the lead screw through the first pulley and the connecting belt. The drive motor realizes the rotation of the lead screw. The L-shaped connecting plate installed on the lead screw is fixedly installed at the bottom of the movable frame, thereby effectively realizing the movable frame to slide left and right along the slide rail at the top of the base by the slider.

[0017] 3. In this utility model, during pipe bending, the cylinder at the bottom of the U-shaped frame drives the corresponding connecting rod to move upward, thereby effectively clamping the pipe with the two bending cylinders in the first, second, and third bending pipe structures. The drive mechanism drives the active pulley to rotate, and the active pulley is connected to the driven pulley at the end of the worm gear through a transmission belt. In this way, the worm gear is rotated by the drive mechanism, and one side of the worm gear meshes with three worm wheels. This can achieve the effect of bending one or two or simultaneously in the three bending pipe structures. By rotating the worm gear forward and backward, the worm wheels drive the connecting rod through the rotating cylinder to adjust the corresponding adjusting seat and bending cylinder left and right.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figure 1-13In this embodiment of the utility model, a three-bend adjustable pipe bending mechanism includes a movable frame 10; a first pipe bending structure 11 is fitted on the top of the movable frame 10; the first pipe bending structure 110 includes an adjusting seat 110; two symmetrically arranged pipe bending cylinders 111 are fitted on the top of the adjusting seat 110; the bottom of the adjusting seat 110 is fixedly installed with a connecting rod 18; the connecting rod 18 passes through a rotating cylinder 24; a slot on the connecting rod 18 engages with a protrusion on the temporal part of the rotating cylinder 24; a worm gear 21 is fixedly installed on the outside of the rotating cylinder 24; and both ends of the rotating cylinder 24 are movably installed with mating seats 23.

[0034] The mating seats 23 at both ends of the rotating drum 24 are fixedly installed with the top plate and the floor of the movable frame 10, respectively; the movable frame 10 is also fitted with a second bent pipe structure 12 and a third bent pipe structure 13; wherein, the installation structure of the second bent pipe structure 12 and the third bent pipe structure 13 is the same as the installation structure of the first bent pipe structure 11.

[0035] One end of each of the connecting rods 18, away from the first bend structure 11, the second bend structure 12, and the third bend structure 13, extends into the U-shaped frame 17 fixedly installed at the bottom of the movable frame 10, and is connected to the corresponding cylinder rod of the cylinder 19 via a coupling 25.

[0036] By adopting the above technical solution, during use, the conveyor belt moving frame 10 above the pipe end to be bent is moved left and right along the base 1 by the lead screw 7, so that the first bending pipe structure 11, the second bending pipe structure 12 and the third bending pipe structure 13 are moved to the bottom of the corresponding pipe. Then, the bending pipe cylinder 111 in the bending pipe structure is moved upward by the cylinder 19, so that the displacement corresponds to both sides of the pipe. Finally, the adjustment seat 110 is rotated by the meshing between the worm gear 21 and the worm 22, so as to effectively achieve the pipe bending effect.

[0037] In this embodiment, a worm 22 is provided on one side of each of the plurality of worm gears 21 and is meshed with the worm; both ends of the worm 22 are movably mounted to the movable frame 10 via bearings; one end of the worm 22 extends to the outside of the movable frame 10 and is fixedly mounted with a driven pulley 16; the driven pulley 16 is connected to a driving pulley 14 movably mounted on the side wall of the movable frame 10 via a transmission belt 15; the driving pulley 14 is fixedly mounted to the drive mechanism.

[0038] The movable frame 10 has sliders 9 fixedly installed at both ends on one side of the U-shaped frame 17; the sliders 9 are slidably installed with the slide rails 8 on the base 1.

[0039] By adopting the above technical solution, when adjusting the movable frame 10, the drive motor 2 on the side plate 3 is connected to the second pulley 6 at one end of the lead screw 7 through the first pulley 4 and the connecting belt 5. The drive motor 2 realizes the rotation of the lead screw 7. The L-shaped connecting plate 20 installed on the lead screw 7 is fixedly installed at the bottom of the movable frame 10, thereby effectively realizing the movable frame 10 sliding left and right along the slide rail 8 at the top of the base 1 by the slider 9.

[0040] In this embodiment, the two ends of the base 1 are movably mounted with lead screws 7 via bearings; an L-shaped connecting plate 20 is fitted onto the lead screws 7; the L-shaped connecting plate 20 is fixedly installed at the bottom of the movable frame 10.

[0041] One end of the lead screw 7 extends to the outside of the base 1 and is fixedly mounted with a second pulley 6; the second pulley 6 is connected to the first pulley 4 on the output shaft of the drive motor 2 via a connecting belt 5; the drive motor 2 is fixedly mounted on the inside of the side plate 3 at one bottom end of the base 1.

[0042] By adopting the above technical solution, when bending the pipe, the cylinder 19 at the bottom of the U-shaped frame 17 drives the corresponding connecting rod 18 to move upward, thereby effectively clamping the pipe with the two bending cylinders 111 in the first bending pipe structure 11, the second bending pipe structure 12, and the third bending pipe structure 13. The drive mechanism drives the active pulley 14 to rotate, and the active pulley 14 is connected to the driven pulley 16 at the end of the worm 22 through the transmission belt 15. In this way, the worm 22 is rotated by the drive mechanism. One side of the worm 22 meshes with the three worm wheels 21, so that one or two of the three bending pipe structures can be bent simultaneously. By rotating the worm 22 forward and backward, the worm wheels 21 drive the connecting rod 18 through the rotating cylinder 24 to adjust the corresponding adjusting seat 110 and bending cylinder 111 left and right.

[0043] The working principle of this utility model is as follows: When in use, the upper part of the conveyor belt moving frame 10 of the pipe end to be bent is moved left and right along the base 1 by the lead screw 7, so as to move the first bending pipe structure 11, the second bending pipe structure 12 and the third bending pipe structure 13 to the bottom of the corresponding pipe. Then, the bending pipe cylinder 111 in the bending pipe structure is moved upward by the cylinder 19, so as to move to the two sides of the corresponding pipe. Then, the rotation of the adjusting seat 110 is achieved by the meshing between the worm gear 21 and the worm 22, thereby effectively achieving the pipe bending effect.

[0044] When adjusting the movable frame 10, the drive motor 2 on the side plate 3 is connected to the second pulley 6 at one end of the lead screw 7 through the first pulley 4 and the connecting belt 5. The drive motor 2 drives the lead screw 7 to rotate. The L-shaped connecting plate 20 installed on the lead screw 7 is fixedly installed at the bottom of the movable frame 10, thereby effectively enabling the movable frame 10 to slide left and right along the slide rail 8 at the top of the base 1 via the slider 9.

[0045] When bending the pipe, the cylinder 19 at the bottom of the U-shaped frame 17 drives the corresponding connecting rod 18 to move upward, thereby effectively clamping the pipe with the two bending cylinders 111 in the first bending structure 11, the second bending structure 12, and the third bending structure 13. The drive mechanism drives the active pulley 14 to rotate, and the active pulley 14 is connected to the driven pulley 16 at the end of the worm 22 through the transmission belt 15. In this way, the worm 22 is rotated by the drive mechanism. One side of the worm 22 meshes with the three worm wheels 21, so that one or two of the three bending structures can be bent simultaneously. The forward and reverse rotation of the worm 22 causes the worm wheels 21 to drive the connecting rod 18 through the rotating cylinder 24 to adjust the corresponding adjusting seat 110 and bending cylinder 111 left and right.
