Description

Technical Field

[0001] This utility model relates to the field of pipe bending equipment technology, specifically a pipe bending device. Background Technology

[0002] When bending metal pipes, a bending device is required. To facilitate the positioning and fixing of the metal pipe, existing methods involve setting up a long metal rod with a guide tube at one end. The guide tube is suspended in the air. After the metal pipe is placed on the guide tube, the guide tube and the metal rod keep the metal pipe suspended, facilitating subsequent positioning and fixing. However, due to the length of the metal rod and guide tube, and the fact that only one end of the rod and guide tube is fixed to the workbench, the metal rod and guide tube are prone to swaying. When placing the metal pipe on the guide tube, the operator needs to stabilize the guide tube with one hand while supporting the metal pipe with the other. Since the metal pipe has a certain weight, supporting it with one hand is quite strenuous, resulting in high labor intensity and inconvenience. Utility Model Content

[0003] The purpose of this invention is to provide a pipe bending device that aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the pipe bending device includes: Installation platform; A holding part is provided on the mounting platform and is used to hold the pipe body to be bent; The pipe bending section is mounted on the mounting platform. The pipe bending section is used to fix the pipe body and can drive the fixed pipe body to bend. A fixing part is provided on the mounting platform and is used to limit the swing of the tail end of the tube. The movable part is set on the mounting platform and located on one side of the bend section. The movable part is used to keep the pipe body in contact with the bend section when bending the pipe.

[0005] Preferably, the retaining part includes a fixing plate disposed at one end of the mounting platform, a guide rod disposed on one side of the fixing plate, a guide tube disposed at one end of the guide rod, the front end of the guide tube being configured as a semi-circular arc, the inner diameter of the tube being slightly larger than the outer diameter of the guide tube, a support plate disposed on the guide rod, a guide rail disposed at the lower end of the support plate, and a guide groove for the movement of the guide rail being provided on the mounting platform.

[0006] Preferably, the pipe bending section includes a main pipe bending wheel, on which a main shaft is mounted. The main shaft is rotatably connected to a mounting platform. A motor is mounted on the lower part of the mounting platform, and a worm gear is mounted on the output end of the motor. A worm wheel that cooperates with the worm gear is mounted on the lower end of the main shaft. An extension section is mounted on the main pipe bending wheel, and an arc-shaped groove for accommodating the pipe body is formed on the extension section. An installation groove is formed on one side of the installation groove, and a sleeve is provided on one side of the installation groove. A screw is threadedly connected to the inside of the sleeve, and a screw cap is provided on one end of the screw. The section also includes a pressure frame, with a pressing groove on one end and a guide cylinder that is slidably connected to the sleeve on the other end of the pressure frame.

[0007] Preferably, the fixing part includes a bending wheel, which is rotatably connected to the mounting platform. The bending wheel and the main bending wheel are located on opposite sides of the guide tube. A pulley is provided on the mounting platform, and a take-up wheel is provided on the bending wheel. The part also includes a rope, one end of which is fixedly connected to a support plate. The other end of the rope passes over the pulley, is fixed, and is wound around the take-up wheel. An eccentric handle is provided on the upper surface of the take-up wheel.

[0008] Preferably, the movable part includes a swing arm, which is rotatably connected to the mounting platform. One end of the swing arm is provided with a secondary bent tube wheel. A guide cavity is provided on the swing arm. A limit rod is slidably connected to the swing arm. A limit piece is provided on the limit rod. The limit piece is located inside the guide cavity. A spring is provided inside the guide cavity. The limit piece is located below the spring. A positioning hole is provided on the mounting platform.

[0009] The beneficial effects of this utility model are: When the tube is fitted onto the guide tube, the guide tube is unlikely to swing due to the support plate supporting the guide rod and the guide tube. Therefore, the operator does not need to stabilize the guide tube; they can hold the tube with both hands and fit it onto the guide tube. This two-handed operation reduces the installation stress of the tube and improves the ease of installation. Furthermore, when the tube is bent, the friction between the tube and the bending wheel drives the bending wheel to rotate, which in turn drives the take-up reel to wind up the rope. This causes the support plate to move towards the guide tube, eliminating the need for continuous control of the support plate's reset. The support plate only needs to be reset in specific situations where it fails to reset effectively, further improving ease of use. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-8 As shown, a pipe bending device includes: Mounting platform 1; The retaining part is provided on the mounting platform 1 and is used to hold the pipe body 2 to be bent. The pipe bending section is set on the mounting platform 1. The pipe bending section is used to fix the pipe body 2 and can drive the fixed pipe body 2 to bend. A fixing part is provided on the mounting platform 1, and the fixing part is used to limit the swing of the tail of the tube body 2. The movable part is set on the mounting platform 1 and located on one side of the bending section. The movable part is used to keep the pipe body 2 in contact with the bending section when bending.

[0021] Furthermore, the retaining part includes a fixing plate 3 disposed at one end of the mounting platform 1, a guide rod 4 disposed on one side of the fixing plate 3, a guide tube 5 disposed at one end of the guide rod 4, the front end of the guide tube 5 is configured as a semi-circular arc, the inner diameter of the tube body 2 is slightly larger than the outer diameter of the guide tube 5, a support plate 6 is disposed on the guide rod 4, a guide rail is disposed at the lower end of the support plate 6, and a guide groove 7 for the movement of the guide rail is provided on the mounting platform 1.

[0022] The guide rod 4 is a solid metal rod, and the guide tube 5 is a hollow metal tube. The guide rod 4 is welded to the metal tube. The support plate 6 is used to support the guide rod 4 and the guide tube 5, so that the guide rod 4 and the guide tube 5 can be kept as horizontal as possible on the mounting platform 1. Before bending the tube body 2, the tube body 2 needs to be inserted into the surface of the guide tube 5. The guide tube 5, the guide rod 4 and the support plate 6 support the tube body 2 and perform preliminary positioning of the tube body 2, which facilitates the fixing of the tube body 2 in the bending part.

[0023] After the tube 2 is fitted onto the guide tube 5, one end of the tube 2 will abut against the support plate 6. Through the cooperation of the guide rail on the support plate 6 and the guide groove 7 on the mounting platform 1, the support plate 6 can move along the guide rod 4, thus preventing the support plate 6 from obstructing the tube 2 from being fitted onto the guide tube 5.

[0024] Furthermore, the pipe bending section includes a main pipe bending wheel 8, on which a main shaft 9 is mounted. The main shaft 9 is rotatably connected to the mounting platform 1. A motor 10 is mounted on the lower part of the mounting platform 1. A worm gear is mounted on the output end of the motor 10. A worm wheel 11 that cooperates with the worm gear is mounted on the lower end of the main shaft 9. An extension 12 is mounted on the main pipe bending wheel 8. An arc-shaped groove for accommodating the pipe body 2 is opened on the extension 12. An installation groove 13 is mounted on one end of the extension 12. A sleeve 14 is mounted on one side of the installation groove 13. A screw 15 is threadedly connected to the inside of the sleeve 14. A screw cap 16 is mounted on one end of the screw 15. The section also includes a pressure frame 17. A compression groove is mounted on one end of the pressure frame 17. A guide cylinder 18 that is slidably connected to the sleeve 14 is mounted on the other end of the pressure frame 17.

[0025] After the tube body 2 is installed on the guide tube 5, the front end of the tube body 2 is moved into the mounting groove 13. Then, the screw 15 is rotated by the screw cap 16. The screw 15 is connected to the sleeve 14 by threads, so that the screw 15 is continuously screwed into the sleeve 14. The front end of the screw 15 will abut against the pressure frame 17 and push the pressure frame 17 to move towards the tube body 2. Then, the tube body 2 is locked and fixed by the pressure frame 17 and the extension part 12.

[0026] After the pipe body 2 is locked and fixed, the movable part is pressed against the pipe body 2, and then the motor 10 is started. The output end of the motor 10 drives the worm to rotate, and then through the cooperation of the worm and the worm wheel 11, it drives the main shaft 9 and the main bending wheel 8 to rotate. When the main bending wheel 8 rotates, it can drive the pipe body 2 to rotate, realizing the bending operation of the pipe body 2. The motor 10 is controlled by the controller. The rotation angle of the worm wheel 11 can be controlled by controlling the number of rotations of the worm, thereby controlling the bending angle of the pipe body 2. The rotation angle of the main bending wheel 8 can also be controlled by the angle sensor.

[0027] After bending the pipe body 2, when it is necessary to remove the pipe body 2, the screw cap 16 needs to be rotated in the opposite direction so that the screw 15 is unscrewed from the sleeve 14. Then, the staff manually moves the pressure frame 17 away from the pipe body 2. Since the pipe body 2 is not limited by the pressure frame 17, it can be moved away smoothly.

[0028] Furthermore, the fixing part includes a bender wheel 19, which is rotatably connected to the mounting platform 1. The bender wheel 19 and the main bender wheel 8 are located on both sides of the guide tube 5. A pulley 20 is provided on the mounting platform 1, and a take-up wheel 21 is provided on the bender wheel 19. It also includes a rope body 22, one end of which is fixedly connected to the support plate 6. The other end of the rope body 22 passes around the pulley 20 and is fixed and wound around the take-up wheel 21. An eccentric handle 23 is provided on the upper surface of the take-up wheel 21.

[0029] After the pipe body 2 is installed on the guide pipe 5, the pipe body 2 is located between the main bending wheel 8 and the secondary bending wheel 19. When the main bending wheel 8 drives the pipe body 2 to bend, the tail of the pipe body 2 will abut against the secondary bending wheel 19 to prevent the tail of the pipe body 2 from swinging. After the bending of the pipe body 2 is completed, the tail of the pipe body 2 will not completely pass through the secondary bending wheel 19 to prevent the secondary bending wheel 19 from failing to limit the swing of the tail of the pipe body 2.

[0030] When the tube 2 moves, a large frictional force is generated between the tube 2 and the bending wheel 19. Therefore, when the tube 2 moves, the bending wheel 19 will rotate under the action of friction. When the bending wheel 19 rotates, the take-up wheel 21 below the bending wheel 19 will also rotate synchronously and wind up the rope 22 through the pulley 20. During the winding process, the rope 22 will drive the support plate 6 to move. Thus, as the tube 2 moves out of the guide tube 5, the support plate 6 can also move towards the guide tube 5.

[0031] The rope 22 has a certain elasticity, such as being a nylon rope, and is always in a taut state, which can prevent the rope 22 from slipping off the pulley 20 due to slack. After the tube 2 is bent, the support plate 6 has not yet come into contact with the guide tube 5, thus avoiding the impact on the rotation of the bending wheel 19 due to the contact between the support plate 6 and the guide tube 5.

[0032] After the tube 2 is removed from the guide tube 5, if the position of the support plate 6 is far from the position of the guide tube 5, the eccentric handle 23 can be used to drive the bending wheel 19 to rotate, and then the take-up wheel 21 can continue to wind up the rope 22, so that the support plate 6 moves towards the guide tube 5, shortening the distance between the support plate 6 and the guide tube 5, and making it easier to support the guide tube 5.

[0033] Furthermore, the movable part includes a swing arm 24, which is rotatably connected to the mounting platform 1. One end of the swing arm 24 is provided with a secondary bending tube wheel 25. A guide cavity 26 is provided on the swing arm 24. A limit rod 27 is slidably connected to the swing arm 24. A limit piece 28 is provided on the limit rod 27. The limit piece 28 is located inside the guide cavity 26. A spring 29 is provided inside the guide cavity 26. The limit piece 28 is located below the spring 29. A positioning hole 30 is provided on the mounting platform 1.

[0034] After the front end of the tube body 2 is fixed by the pressure frame 17 and the extension part 12, the swing rod 24 needs to be swung on the mounting table 1 by the limiting rod 27. When the limiting rod 27 reaches the position of the positioning hole 30, under the action of the spring 29, it will push the limiting piece 28 to move downward and drive the limiting rod 27 to move downward. The lower end of the limiting rod 27 will enter the positioning hole 30. After the lower end of the limiting rod 27 enters the positioning hole 30, the swing rod 24 can no longer move on the mounting table 1. At this time, the secondary bending wheel 25 contacts the surface of the tube body 2. At this time, the secondary bending wheel 25 can cooperate with the main bending wheel 8 to achieve accurate bending of the tube body 2.

[0035] When completing the bending of pipe body 2 and removing pipe body 2, the auxiliary bending wheel 25 needs to be moved away first. Specifically, control the limiting rod 27 and move it upward to compress the spring 29 in the guide cavity 26. When the lower end of the limiting rod 27 is completely removed from the positioning hole 30, the crossbar is controlled to swing on the mounting platform 1 by the limiting rod 27, thereby increasing the distance between the auxiliary bending wheel 25 and the main bending wheel 8, so that pipe body 2 can be easily removed. When the lower end of the limiting rod 27 is located outside the positioning hole 30 on the mounting platform 1, the worker does not need to lift the limiting rod 27, and the limiting rod 27 can move along the surface of the mounting platform 1.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
