Description

Technical Field

[0001] This utility model relates to the field of bending devices, and in particular to a bending device for processing metal pipes. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow distribution, sealing, and support. Based on different processing techniques, they are divided into four main categories: butt-welded pipe fittings, socket-welded pipe fittings, threaded pipe fittings, and flanged pipe fittings. Metal pipe fittings are an important component in the connection pipelines of modern industrial equipment. They have properties such as high temperature resistance, low temperature resistance, aging resistance, and corrosion resistance, and are therefore widely used. In practical applications, pipes in different directions are required, so bending processing is necessary during the processing and production of metal pipe fittings.

[0003] In the metal pipe processing and production process, when bending, the pipe is generally placed on a clamp and force is applied to push the pipe into contact with the bending die, so that the pipe is bent at a certain angle on the bending die. However, in actual use, existing metal pipe bending devices make it difficult to quickly and easily remove the bent pipe from the device after bending. At the same time, existing bending devices mostly use two sets of rollers to limit and apply force to the pipe during the bending operation, which has low limiting and stability of the pipe. It is often necessary to manually fix the pipe, which leads to the need to improve the overall convenience of the device in actual use.

[0004] Therefore, this utility model proposes a bending device for processing metal pipe fittings. Utility Model Content

[0026] Please see Figure 1-5 This utility model provides a technical solution for a bending device for processing metal pipe fittings:

[0027] The system includes a base 1 and a worktable 2. A first support platform 3, a second support platform 4, and a third support platform 8 are fixedly connected to the surface of the worktable 2. A mounting base plate 5 and a cylinder 6 are mounted on top of the worktable 2. A drive gear plate 7 is fixedly connected to the output end of the cylinder 6. A guide assembly 9 and a positioning assembly 10 are fixedly connected to the surface of the worktable 2. A bending assembly 11 is movably connected to the top of the guide assembly 9. The guide assembly 9 includes a guide platform 12 and a bending handle 13 fixedly connected to each other. A bending handle 13 is fixedly connected to the top of its top end. The first limiting head 14 and the positioning component 10 include a positioning platform 15 and a fixed platform 16 that are fixedly connected. The positioning platform 15 is also movably connected to the guide platform 12. The bending component 11 includes a first bending roller 17 and a second bending roller 18 that are matched. The top of the first support platform 3 and the inner end of the second support platform 4 are respectively fixedly connected to the third limiting head 20 and the second limiting head 19. A drive gear 21 is matched below the first bending roller 17. A sliding seat 22 is fixedly connected to the inner end of the third support platform 8. The drive tooth plate 7 is also movably sleeved with the sliding seat 22.

[0028] like Figure 1-4 As shown, two sets of first support platforms 3 are arranged laterally adjacent to each other along one side of the top of the workbench 2. The third limiting head 20 is arranged vertically in a "U" shape and is fixedly connected to the top of the first support platform 3 on the right side. The mounting base plate 5 is fixedly connected to the top of the first support platform 3 on the left side. The second support platform 4 and the third support platform 8 are arranged in an "L" shape and are distributed opposite each other. The second limiting head 19 is arranged laterally in a "U" shape and is fixedly connected to the inner end of the second support platform 4. The sliding seat 22 is arranged laterally in a rectangle and is fixedly connected to the inner end of the third support platform 8. The first set of two first support platforms 3 and the third limiting head 20 matched with its top achieve the effect of initial guiding and limiting the metal pipe. The other set of two first support platforms 3 and the mounting base plate 5 matched with its top achieve the effect of supporting the cylinder 6 as a whole. The second support platform 4 and the second limiting head 19 at its top achieve the effect of bending and limiting the metal pipe. The third support platform 8 and the sliding seat 22 at its top achieve the effect of limiting and guiding the drive tooth plate 7.

[0029] like Figure 2As shown, the fixed platform 16 is a rectangular platform, fixedly connected to the surface of the workbench 2, while the positioning platform 15 is a double-layered "U"-shaped platform facing outwards, with its outer end having an arc transition. The bent handle 13 is "L"-shaped and protrudes outwards, and the first limiting head 14 is "U"-shaped and faces inwards. The guide platform 12 consists of two sets of rectangular plates distributed vertically and two sets of shafts between the two sets of rectangular plates, and its overall shape is "U". The inner end of the guide platform 12 is movably connected to the outer end of the positioning platform 15 through the shafts therein, and the top ends of the two sets of shafts in the guide platform 12 are connected through... The guide assembly 9 is supported and guided by a set of shafts, a first bending roller 17 and a drive gear 21, and a second bending roller 18. The guide assembly 9 is supported and guided by a fixed platform 16 and a positioning platform 15. The bending handle 13 drives the guide platform 12 to rotate and adjust. The first limiting head 14 limits and guides the outer end of the metal pipe. The guide platform 12 drives the first bending roller 17 and the second bending roller 18 to adjust their angles, thus performing a bending operation on the metal pipe.

[0030] like Figure 2 and Figure 5 As shown, the first bending roller 17 is located above the movable connection end of the guide table 12 and the positioning table 15, and the second bending roller 18 is located above the outer end of the guide table 12. The surface of the second bending roller 18 is provided with an annular inner groove. A set of protruding semi-annular protrusions is also provided on the outside of the first bending roller 17. The surface of the semi-annular protrusions is provided with an arc-shaped inner groove. The drive gear 21 and the first bending roller 17 are fixedly connected in an upper and lower position. It is fitted with the drive gear plate 7 at the same horizontal position. The drive gear 21 achieves the effect of driving the first bending roller 17 to rotate and adjust. The first bending roller 17 and the second bending roller 18 achieve the effect of limiting the bending operation of the metal pipe. At the same time, the set of semi-annular protrusions on the outside of the first bending roller 17 facilitates the adjustment of the limiting operation of the metal pipe.

[0031] After the pipe passes through the semi-annular protrusion and the second bending roller 18 outside the first bending roller 17, the user rotates the guide assembly 9 around the positioning assembly 10 using the bending handle 13. This causes the guide assembly 9 and the positioning assembly 10 to rotate from a horizontal position to a right angle, which in turn drives the second bending roller 18 to rotate to the left, from the right side of the first bending roller 17 to its front position, thus achieving the bending operation of the metal pipe. During the rotation of the bending handle 13, as the metal pipe is bent, the first... A limiting head 14 gradually comes into contact with the outer end of the metal tube to limit its movement, making it easier to bend the metal tube. After bending, the drive tooth plate 7 slides inside and outside the sliding seat 22 under the control of the cylinder 6, driving the drive gear 21 to rotate. The rotation of the drive gear 21 drives the first bending roller 17, which is fixedly connected to it, to rotate, causing the semi-annular protrusion on the outer sleeve of the metal tube and the first bending roller 17 to separate. At this time, the distance between the metal tube and the two sets of bending rollers increases, so that the metal tube can be taken out between the two sets of bending rollers.

[0032] The working principle of this utility model is as follows: When using this device, the metal pipe first passes through the third limiting head 20, the second limiting head 19, the first bending roller 17, and the second bending roller 18 in sequence. Then, the user controls the guide assembly 9 to rotate to the left through the bending handle 13, so that the second bending roller 18 and the first bending roller 17 rotate from the horizontal state to the vertical state, realizing the bending operation of the metal pipe. When the bending is completed and the metal pipe needs to be removed, the drive tooth plate 7 drives the drive gear 21 to rotate, so that the first bending roller 17 rotates, and the semi-annular protrusion on its outer sleeve rotates to the other side and separates from the pipe. At this time, the metal pipe can be removed. During the bending process, the multiple limiting head structures can effectively ensure the stability of the metal pipe from the introduction to the completion of the bending. The adjustable first bending roller 17 realizes the rapid removal and separation of the metal pipe.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
