Technical Field

[0001] The utility model belongs to the technical field of steel pipe manufacturing equipment, and particularly relates to a welding device for steel pipe manufacturing. Background Art

[0002] A steel pipe is a steel product with a hollow cross-section, and its length is much greater than its diameter or circumference. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat energy, manufacturing mechanical parts and containers, but also an economical steel product.

[0003] Steel pipes can be divided into two categories according to the production method: seamless steel pipes and welded steel pipes. Welded steel pipes are simply referred to as welded pipes. When manufacturing welded steel pipes, a welding device is required to weld the steel pipes, so as to connect two steel pipes together. Although the existing welding devices can play a basic welding role, when welding at an angle between two steel pipes, one of the steel pipes cannot be moved and rotated, resulting in a significant reduction in the flexibility of use. Therefore, it needs to be improved. Summary of the Utility Model

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 5 As shown in the figure, the present invention provides a welding device for steel pipe manufacturing, including a processing table 1. On the left side of the top of the processing table 1, two first support pillars 2 are fixedly installed. The number of the first support pillars 2 is two. On the top of both first support pillars 2, fixed brackets 3 are fixedly installed. In the middle of the top end of the processing table 1, a second support pillar 4 is fixedly installed. The top of the second support pillar 4 is hinged with a rotating plate 5. On the right side of the top of the rotating plate 5, a movable bracket 6 is fixedly installed. The top of the movable bracket 6 is fixedly connected with a support 7. Inside the top end of the support 7, a threaded rod 8 is threadedly sleeved. The bottom end of the threaded rod 8 penetrates through the support 7 and extends into the inside of the support 7 and is movably connected with a pressing plate 9. The outer surface of the pressing plate 9 is movably connected with the inner wall of the support 7. On the right side of the top of the processing table 1, a limiting plate 10 is fixedly installed. A sliding plate 11 is movably connected between the limiting plates 10. The bottom of the sliding plate 11 is movably connected with the top of the processing table 1. The top of the sliding plate 11 is fixedly connected with a vertical rod 12. Inside the top end of the vertical rod 12, a round shaft 13 is movably sleeved. The top of the round shaft 13 is fixedly connected with a moving bracket 14. The bottom of the moving bracket 14 is movably connected with the top of the vertical rod 12.

[0023] The operator places a steel pipe inside the two fixed brackets 3 and another steel pipe inside the movable bracket 6 and the moving bracket 14, so that the two steel pipes are in contact, thereby enabling welding operations on the steel pipes. When angled welding of the steel pipes is required, the threaded rod 8 can be rotated, causing the threaded rod 8 to drive the pressing plate 9 to move downward, thereby enabling clamping and fixing of the steel pipes. Thus, when the vertical rod 12 moves, it drives the steel pipes to rotate around the second support pillar 4 as the axis, and further enables angled welding between the steel pipes.

[0024] Among them, a fixed rod 15 is fixedly installed on the top of the processing table 1 and is located on the left side of the limiting plate 10. A scale pattern 16 is provided on the top of the fixed rod 15.

[0025] As a technical optimization scheme of the present utility model, by providing the scale pattern 16, the operator can accurately master the rotation angle of the steel pipe.

[0026] Among them, the bottom of the left side of the vertical rod 12 is fixedly connected with a pointer 17, and the top of the pointer 17 is movably connected with the top of the limiting plate 10.

[0027] As a technical optimization scheme of the present utility model, by providing the pointer 17, the pointer 17 can point to the scale pattern 16, so as to facilitate the operator to observe.

[0028] Among them, a chute 18 is provided inside the right side of the processing table 1, and a connecting rod 23 is fixedly connected to the bottom of the sliding plate 11.

[0029] As a technical optimization scheme of the present utility model, when the connecting rod 23 moves, it will drive the sliding plate 11 to move along the inner surface of the limiting plate 10.

[0030] Among them, a motor 19 is fixedly connected to the right side of the back of the processing table 1, and the other end of the output shaft of the motor 19 is fixedly connected to a rotating shaft 20.

[0031] As a technical optimization scheme of the present utility model, the operator can start the motor 19 to make the rotating shaft 20 rotate.

[0032] Among them, a rotating rod 21 is fixedly sleeved on the outer surface of the rotating shaft 20, and the other end of the rotating rod 21 is hinged with a hinged rod 22.

[0033] As a technical optimization scheme of the present utility model, when the rotating rod 21 rotates, it will drive the hinged rod 22 to move.

[0034] Among them, the inner surface of the front end of the hinged rod 22 is movably sleeved on the outer surface of the connecting rod 23, and the top of the hinged rod 22 is movably connected to the bottom of the processing table 1.

[0035] As a technical optimization scheme of the present utility model, when the rotating rod 21 rotates, it will drive the connecting rod 23 to move through the hinged rod 22.

[0036] The working principle and usage process of the present utility model:

[0037] When an operator needs to weld steel pipes, first place one steel pipe inside the two fixed brackets 3, and then place another steel pipe inside the movable bracket 6 and the moving bracket 14, so that the joints of the two steel pipes are located above the second support column 4 and are in contact with each other, thus enabling the welding of the steel pipes. When angled welding of the steel pipes is required, rotate the threaded rod 8, causing the threaded rod 8 to drive the pressing plate 9 downward to fix the steel pipe. When the sliding plate 11 moves along the inner surface of the limiting plate 10, it will drive the steel pipe to rotate around the second support column 4 through the moving bracket 14, thereby completing the adjustment of the rotation angle of the steel pipe.

[0038] The operator starts the motor 19, causing the rotating shaft 20 to drive the rotating rod 21 to rotate, and further enabling the articulated rod 22 to push the connecting rod 23 to move. As a result, the connecting rod 23 drives the pointer 17 to move through the sliding plate 11 and the vertical rod 12. At this time, the operator can accurately adjust the included angle between the two steel pipes by observing the scale pattern 16 pointed to by the pointer 17, improving the quality of welding the steel pipes.
