Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, and in particular to a pipe bending machine that is easy to carry and assemble. Background Technology

[0002] A pipe bending machine is a device that bends pipes. Metal or non-metal pipes are used in many fields, including industry, construction, chemical industry, and power industry. They have a wide range of applications and are an essential raw material. When metal or non-metal pipes are used on construction sites, the actual usage environment limits the operation and requires bending at different angles to transform the originally straight metal or non-metal pipes into shapes with curved bends.

[0003] The prior art, disclosed in publication number CN221537737U, discloses a portable handheld hydraulic pipe bending machine, including a bending table and a bending pipe. The bending pipe is positioned at the top of the bending table, a support mechanism is provided at the bottom of the bending table, and a bending mechanism is provided at the top of the bending table. This portable handheld hydraulic pipe bending machine, by incorporating the bending mechanism, can quickly bend the pipe during the bending process, thereby increasing the bending speed of the device. This solves the problem mentioned in the prior art where the device is not easy to quickly position the bending pipe during the bending process, thus affecting the bending speed. The support mechanism not only allows for convenient carrying of the entire device but also provides stable support for the bending table, thereby improving the bending stability of the device. Furthermore, the mechanism has a simple structure and is relatively easy to operate.

[0004] However, the existing technologies still have certain shortcomings in use: First, the pipeline layout on the construction site requires frequent relocation of the construction area. The existing technology structure lacks a corresponding movable structure, resulting in high labor intensity for workers when moving between different work positions or transporting the equipment to the construction site, and it is inconvenient to carry. Second, depending on the needs of the construction site, the required bending angles of the pipelines vary, and there are some angles that are not commonly used. The existing technology structure can only process conventional angles such as 30°, 45°, 60°, and 90°, and the accuracy of bending at other special angles is not high, limiting its applicability. Finally, the existing technology structure is inconvenient to disassemble and install, and the cost is relatively high. Therefore, further improvements to the existing technology are needed.

[0035] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0036] Please see Figure 1-10The present invention will now be described in detail with reference to the accompanying drawings and embodiments: A portable and easily assembled pipe bending machine includes a housing assembly 1, which includes a frame 2. The bottom surface of the frame 2 is provided with several self-locking casters 3. Threaded grooves 4 are provided at the four corners of the top surface of the frame 2. A top plate 5 is provided on the top surface of the frame 2. Through grooves 6 corresponding to the positions of the threaded grooves 4 are provided at the four corners of the top plate 5. The top plate 5 can be fixed to the frame 2 by bolts 7 passing through the through grooves 6 and threadedly engaging with the threaded grooves 4. A pipe bending mechanism 8 for easy installation and disassembly is provided on the top surface of the top plate 5. The casters 3 with locking function are prior art and will not be described further here.

[0037] Please see Figure 1-4 The pipe bending mechanism 8 includes a guide bending assembly 9, a bending assembly 10, and a limiting assembly 11. The guide bending assembly 9 includes a limiting rod 12 fixedly mounted on the top surface of the top plate 5 and a guide wheel 13 with a groove. A limiting ring 14 is fixedly mounted in the middle of the limiting rod 12. Four limiting strips 15 are arranged in a ring on the limiting ring 14. The upper end of the limiting rod 12 is provided with a thread. The bottom surface of the guide wheel 13 is provided with a ring boss 16. A cylindrical groove 17 adapted to the limiting rod 12 is opened in the middle of the guide wheel 13. A limiting groove 18 adapted to the limiting strips 15 is arranged in a ring on the inner wall of the cylindrical groove 17. A limiting groove 19 adapted to the limiting ring 14 is opened on the bottom surface of the guide wheel 13. The guide wheel 13 can be fixed on the limiting rod 12 by the cooperation of the nut and the limiting ring 14.

[0038] When installing the guide wheel 13, first place the second limiting groove 19 of the guide wheel 13 downwards, then align the first limiting groove 18 and the first limiting strip 15, and insert it into the first limiting rod 12. At this time, the annular part 14 is in the second limiting groove 19. Then screw the first nut into the upper end of the first limiting rod 12 until the first nut is in full contact with the guide wheel 13, and the guide wheel 13 can be stabilized on the first limiting rod 12.

[0039] Please see Figure 4 An angle gauge 20 is provided around the top surface of the guide wheel 13, which facilitates the determination of the bending angle.

[0040] Please see Figure 5-8The bending assembly 10 includes a rotating bar 21 and a bending wheel 22 with a groove. One end of the rotating bar 21 is sleeved on and rotates on a limiting rod 12, and the rotating bar 21 is located below the limiting ring 14. A rectangular groove 23 is formed on the top surface of the rotating bar 21 on the side away from the limiting rod 12. A rectangular block 24 is slidably arranged in the rectangular groove 23. A disc 25 is fixedly arranged on the rectangular block 24. A limiting rod 26 is fixedly arranged on the top surface of the disc 25. The outer wall of the limiting rod 26... The annular array has four limiting bars 27. The top surface of the limiting rod 26 has a threaded groove 2. The top surface of the bending wheel 22 has a cylindrical groove 28 that is adapted to the limiting rod 26. The inner wall of the cylindrical groove 28 has a ring array of limiting grooves 29 that are adapted to the limiting bars 27. The threaded groove 2 of the limiting rod 26 has a sealing cap 30 in internal thread engagement. The bending wheel 22 can be stably mounted on the limiting rod 26 through the engagement of the sealing cap 30, the threaded groove 2, and the disc 25.

[0041] Please see Figure 8 The bending assembly 10 also includes a locking assembly for stabilizing the position of the rectangular block 24. The locking assembly includes a bolt 31, a nut 32, and a washer 33. The rotating bar 21 has a sliding groove 34 that passes through the rectangular groove 23 on its side. The rectangular block 24, which is located in the sliding groove 34, has a through hole 35 on its side. One end of the bolt 31 is passed through the through hole 35 from the sliding groove 34 on one side to the sliding groove 34 on the other side. Then, the nut 32 is tightened on the bolt 31. The rectangular block 24 can be stabilized in any position in the rectangular groove 23. The distance between the guide wheel 13 and the bending wheel 22 can be adjusted to adapt to the bending of pipes of different specifications.

[0042] Please see Figure 6 , 8 A guide 36 is fixedly installed on the top surface of the bending wheel 22. The guide 36 is arrow-shaped. Through the cooperation of the guide 36 and the angle gauge 20, the user can accurately bend the pipe to the required angle.

[0043] Furthermore, the thickness of the disc 25 is adapted to the thickness of the annular boss 16, so that the groove of the bending wheel 22 is aligned with the groove of the guide wheel 13, that is, the guide wheel 13 and the bending wheel 22 are on the same horizontal plane, so as to facilitate the clamping of the pipe through the two grooves.

[0044] Please see Figure 5-6 8. A cross-shaped extension rod 37 is provided on the right side of the rotating bar 21. The vertical end of the extension rod 37 is inserted into the right side of the rotating bar 21. By setting the extension rod 37, the lever arm of the rotating bar 21 when rotating around the limiting rod 12 is increased, thereby reducing the labor intensity of the user.

[0045] Please see Figure 9The limiting component 11 includes a mounting block 38. A T-shaped groove 39 communicating with the side of the top plate 5 is opened on the top surface of the top plate 5. A T-shaped block 40 is slidably arranged in the T-shaped groove 39. The mounting block 38 is fixedly arranged on the top surface of the T-shaped block 40, and the bottom surface of the mounting block 38 is in sliding contact with the top surface of the top plate 5. A moving groove 41 is opened on the top surface of the mounting block 38. A lead screw 42 is rotatably arranged in the moving groove 41. One end of the lead screw 42 passes through the moving groove 41 and extends a portion. A rotating part 43 is fixedly arranged on the extended end. A moving part 44 is threaded on the lead screw 42. The lower end of the moving part 44 slides in the moving groove 41. An arc-shaped groove 45 adapted to the groove of the bending wheel 22 is opened on the side of the upper end of the moving part 44 facing the guide wheel 13, and the arc-shaped groove 45 and the groove of the bending wheel 22 are at the same height.

[0046] The arc-shaped groove 45 of the moving part 44 limits and stabilizes one end of the pipe, thereby facilitating the bending wheel 22 to rotate and bend the other end of the pipe along the guide wheel 13 at a corresponding angle.

[0047] Please see Figure 10 The bottom surface inside the frame 2 is provided with several storage spaces 46 of different sizes. The disassembled parts can be stored in the storage spaces 46 of different sizes, so as to facilitate the storage of the parts after use and prevent damage to the parts.

[0048] Please see Figure 10 The top plate 5 has a circular opening 47 on its top surface, and the inner top surface of the frame 2 has a threaded groove 3 48 corresponding to the position of the circular opening 47. After the bending mechanism 8 is used, the threaded end of the extension rod 37 can be passed through the circular opening 47 and screwed into the threaded groove 3 48 so that the entire box assembly 1 can be moved by the extension rod 37, reducing the labor intensity of the user and making it easy to carry and move.

[0049] When this solution needs to be assembled and used, first unscrew the bolts 7 at the four corners of the top plate 5, then flip the top plate 5 so that the limiting rod 12 on the top plate 5 faces upward (in the initial state, the limiting rod 12 and the rotating bar 21 are on the top plate 5). Then take out each part, and then fix the top plate 5 to the frame 2 again with the bolts 7. Then, turn the limiting groove 19 of the guide wheel 13 downward, then align the limiting groove 18 and the limiting bar 15, and insert them into the limiting rod 12. Then, screw the nut into the upper end of the limiting rod 12 until the nut is in full contact with the guide wheel 13, thereby stabilizing the guide wheel 13 on the limiting rod 12.

[0050] After the guide wheel 13 is installed, slide the T-block 40 below the mounting block 38 into the T-slot 39, then insert the rectangular block 24 into the rectangular slot 23, and then insert the bending wheel 22 into the limiting rod 26. Finally, screw the sealing cap 30 into the threaded groove at the top of the limiting rod 26 to fix the bending wheel 22 onto the limiting rod 26. It should be noted that the pointing piece 36 on the bending wheel 22 must be aligned with the 0° on the angle gauge 20 on the top surface of the guide wheel 13.

[0051] After the guide wheel 13 is installed, the pipe is passed through the gap between the guide wheel 13 and the bending wheel 22. Then, the rectangular block 24 is moved so that the bending wheel 22 cooperates with the guide wheel 13 to initially clamp the pipe. Then, a washer 33 is put on the bolt 2 31 and passed through the slide groove 34 and the through hole 35. Then, a washer 33 is put on the other end of the bolt 2 31 and tightened by the nut 2 32 to fix the position of the rectangular block 24, thereby stabilizing the distance between the bending wheel 22 and the guide wheel 13.

[0052] Next, adjust the position of the moving part 44 by rotating part 43 to stabilize one end of the pipe. Then, insert one end of the extension rod 37 to the right side of the rotating bar 21 to increase the lever arm. Then push the extension rod 37 clockwise, and the rotating bar 21 rotates clockwise around the limit rod 12. Then, the groove of the bending wheel 22 bends the pipe around the groove of the guide wheel 13. The bending angle can be determined according to which scale the pointing part 36 points to. For example, after the bending wheel 22 rotates, the pointing part 36 points to 90°, at this time the pipe is bent by 90°. After the pipe is bent, loosen the nut 2 32 a little to easily remove the bent pipe. Thus, the pipe can be bent at any angle, which is convenient and quick.

[0053] When the work area changes, the entire device can be pushed or pulled directly.

[0054] When disassembly is required after work is completed, firstly, the mounting block 38 can be slid directly out of the T-slot 39. Then, unscrew the nut 1 on the guide wheel 13, and remove the guide wheel 13 from the limiting rod 12. Next, unscrew the cap 30 above the bending wheel 22, and remove the guide wheel 13 from the limiting rod 26. Then, unscrew the nut 32 on the bolt 21 and pull out the bolt 21 to release the restriction on the rectangular block 24. Then, pull out the rectangular block 24 and the limiting rod 26 together, and then pull out the extension rod 37. At this time, only the limiting rod remains on the top plate 5. Remove the four bolts 12 and 21 from the top plate 5, then remove the top plate 5 and place all parts except the extension rod 37 into the receiving space 46 in the frame 2. Place the top plate 5 on the top surface of the frame 2. Note that at this time, the limit rod 12 and the 21 are inside the frame 2. Then fix the top plate 5 again with the bolts 17. Then pass the extension rod 37 through the round opening 47 and engage it with the threaded groove 38. The entire device can be moved by pulling the extension rod 37, which is convenient and quick, and can also protect the parts.
