Description

Technical Field

[0001] This utility model relates to the field of pipe bending technology, specifically to a large-diameter pipe bending device with an adjustable function. Background Technology

[0002] In industrial production, large-diameter pipe fittings are widely used in petrochemical, municipal engineering, water conservancy construction and other fields. When these pipe fittings are installed and used, they often need to be bent at different angles according to specific working conditions to meet the requirements of pipeline routing.

[0003] However, existing large-diameter pipe bending equipment has some shortcomings. The bending module spacing of traditional equipment is mostly fixed and can only be adapted to pipes of specific diameters. When different specifications of pipes need to be processed, the entire bending module or even the equipment needs to be replaced. This is not only cumbersome and time-consuming, but also significantly increases the equipment procurement and maintenance costs of enterprises, making it difficult to adapt to diverse production needs. Utility Model Content

When the threaded rod is rotated, the threaded transmission drives the connecting block to move up and down along the adjusting groove, thereby causing the upper bending module to move closer to or away from the lower bending module.

[0008] Preferably, a first bearing is fixedly connected to the inner wall of the top of the drive base, and a sliding groove is formed on the outer wall of the top of the drive base.

[0014] (ii) The top-pressing structure, by sliding the slider in the groove and cooperating with the extension and retraction of the hydraulic rod, can adjust the position of the top-pressing rod so that it is accurately aligned with the middle part of the pipe to be bent.

[0021] 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.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a large-diameter pipe bending device with adjustable function, comprising: a drive base 1, a drive structure 2 symmetrically fixedly connected to the outer wall of the top of the drive base 1, a top pressure structure 3 fixedly connected to the outer wall of the top of the drive base 1, and the top pressure structure 3 being located in the middle of the symmetrical drive structure 2; the drive structure 2 includes a support base 21, a support plate 22 fixedly connected to the outer wall of the top of the support base 21, a second bearing 23 fixedly connected to the inner wall of the support plate 22, a rotating rod 24 fixedly connected to the inner wall of the second bearing 23, an adjusting groove 25 being opened inside the rotating rod 24, a lower bending module 26 fixedly connected to the outer wall of the rotating rod 24, an upper bending module 27 slidably connected to the outer wall of the rotating rod 24, a connecting block 271 fixedly connected to the inner wall of the upper bending module 27, anti-slip pads 28 fixedly connected to the outer walls of both the lower bending module 26 and the upper bending module 27, and a threaded rod 29 rotatably connected to the inner wall of the adjusting groove 25.

[0023] The upper bending module 27 is positioned above the lower bending module 26. The outer wall of the connecting block 271 is slidably connected to the inner wall of the adjusting groove 25. The outer wall of the threaded rod 29 is threadedly connected to the inner wall of the connecting block 271. When the threaded rod 29 is rotated, the threaded transmission drives the connecting block 271 to move up and down along the adjusting groove 25, thereby causing the upper bending module 27 to move closer to or further away from the lower bending module 26.

[0024] A first bearing 11 is fixedly connected to the inner wall of the top of the drive base 1, and a sliding groove 12 is provided on the outer wall of the top of the drive base 1.

[0025] The outer wall of the bottom of the support base 21 is fixedly connected to the outer wall of the top of the drive base 1, the outer wall of the rotating rod 24 is fixedly connected to the inner wall of the first bearing 11, and the rotating rod 24 is connected to the motor inside the drive base 1, so that the rotating rod 24 rotates synchronously under the support of the first bearing 11 and the second bearing 23 on the support plate 22.

[0026] The top-pressure structure 3 includes a mounting base 31, a hydraulic rod 32 is fixedly connected to the inner wall of the mounting base 31, a connecting plate 33 is fixedly connected to the outer wall of the hydraulic rod 32, a top-pressure rod 34 is rotatably connected to the inner wall of the connecting plate 33, and a slider 35 is fixedly connected to the outer wall at the bottom of the connecting plate 33.

[0027] The outer wall of the bottom of the mounting base 31 is fixedly connected to the outer wall of the top of the drive base 1. The outer wall of the slider 35 is slidably connected to the inner wall of the slide groove 12. The hydraulic rod 32 is fixed on the mounting base 31 and can drive the connecting plate 33 to slide along the slide groove 12, thereby driving the top pressure rod 34 to move horizontally.

[0028] In use, the core adjustment function of the equipment is realized through the drive structure 2. For large-diameter pipes of different diameters, the distance between the upper bending module 27 and the lower bending module 26 can be adjusted.

[0029] In the drive structure 2, the threaded rod 29 is threadedly connected to the connecting block 271 of the upper bending module 27, and the connecting block 271 is nested in the adjustment groove 25 of the rotating rod 24. When the threaded rod 29 is rotated, the threaded transmission drives the connecting block 271 to move up and down along the adjustment groove 25, thereby driving the upper bending module 27 to move closer to or away from the lower bending module 26. By adjusting the position of the upper bending module 27 of the two symmetrical drive structures 2, the distance between the lower bending module 26 and the upper bending module 27 is adapted to the outer diameter of the pipe to be bent. At this time, the anti-slip pad 28 on the inner wall of the module can increase the friction, which not only prevents the pipe from sliding when clamping, but also prevents the surface of the pipe from being damaged.

[0030] The two ends of the pipe fitting are respectively mounted between the lower bending module 26 and the upper bending module 27 of the two-sided drive structure 2. The initial positioning is achieved through the adjusted spacing. Since the drive structure 2 is symmetrically distributed and the top pressure structure 3 is located in the middle, the bending point of the pipe fitting is naturally aligned with the top pressure rod 34 of the top pressure structure 3, ensuring that the bending force is concentrated at the target position. The slider 35 of the top pressure structure 3 is nested in the slide groove 12 of the drive base 1. The hydraulic rod 32 is fixed on the mounting base 31 and can drive the connecting plate 33 to slide along the slide groove 12, thereby driving the top pressure rod 34 to move horizontally. By extending and retracting the hydraulic rod 32, the position of the top pressure rod 34 is adjusted so that it is accurately aligned with the middle part of the pipe fitting that needs to be bent, providing a stable force point for subsequent bending.

[0031] When the hydraulic rod 32 of the top pressure structure 3 is activated, the output top pressure pushes the top pressure rod 34 to move towards the pipe fitting, applying pressure perpendicular to the pipe fitting axis to the middle part of the pipe fitting. The rotating rods 24 of the two drive structures 2 rotate synchronously under the support of the first bearing 11 and the second bearing 23 on the support plate 22. The rotating rods 24 are connected to the motor inside the drive base 1, driving the two ends of the pipe fitting clamped between the upper bending module 27 and the lower bending module 26 to rotate around the axis of the rotating rods 24. Under the combined action of the middle pressure of the top pressure rod 34 and the rotational tension of the rotating rods 24 at both ends, the middle part of the pipe fitting undergoes plastic deformation due to the force exceeding the material yield limit, and gradually bends to the target angle.
