Description

Technical Field

[0001] This utility model relates to the field of spiral submerged arc welded steel pipe processing technology, specifically to a spiral submerged arc welded steel pipe welding clamping and rotating mechanism. Background Technology

[0002] Spiral submerged arc welded steel pipe, a highly efficient pipe material widely used in industrial fields, owes its name to the unique forming technology employed in its production process. Specifically, it involves coiling and welding steel plates together in a spiral shape to form a continuous tubular structure. "Submerged arc welding" refers to a special process where an electric arc is buried beneath a layer of flux, which not only improves welding efficiency but also ensures stable and reliable weld quality.

[0003] However, existing technologies, such as traditional steel pipe welding clamping mechanisms, lack the ability to rotate the steel pipe, thus requiring manual adjustment or multiple clamping operations, increasing time consumption. Furthermore, the circumferential weld needs to be processed in sections, and uneven heat input in the weld can easily lead to defects such as porosity and incomplete fusion, resulting in high residual stress. Therefore, we provide a spiral submerged arc welding steel pipe welding clamping and rotating mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a spiral submerged arc welded steel pipe welding clamping and rotating mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spiral submerged arc welding steel pipe welding clamping and rotating mechanism, including a processing table, with slots on both sides of the top of the processing table, and sliding grooves on both sides of the inner walls of the two slots. Motors are installed at both ends of one side of the processing table, and bidirectional lead screws are installed inside the two slots. Moving blocks are installed at two different thread positions of the two bidirectional lead screws, and sliders are installed on both sides of the four moving blocks. Clamping rings are installed on the top of the four moving blocks, and fixed shells are installed in the slots of the four clamping rings. Springs are installed inside the multiple fixed shells, and movable columns are installed at one end of each of the multiple springs. Pulleys are installed at the ends of the multiple movable columns away from the springs.

[0006] As a further preferred embodiment of this technical solution, support plates are fixedly connected to both ends of one side of the processing table, and motors are fixedly installed on the top of both support plates.

[0007] As a further preferred embodiment of this technical solution, both output ends of the two motors are fixedly connected to a bidirectional lead screw, and each of the two different threads of the bidirectional lead screw is threaded with a moving block.

[0008] As a further preferred embodiment of this technical solution, sliders are fixedly connected to both sides of the movable block, and the outer side of the sliders is slidably connected to the inner wall of the groove.

[0009] As a further preferred embodiment of this technical solution, a clamping ring is fixedly connected to the top of the movable block, and a fixing shell is fixedly connected to each of the slots opened in the clamping ring.

[0010] As a further preferred embodiment of this technical solution, a spring is fixedly connected inside the fixed shell, and the other end of the spring is fixedly connected to one end of the movable column.

[0011] As a further preferred embodiment of this technical solution, the movable column is slidably connected to the inner wall of the fixed shell, a pulley is rotatably installed at the end of the movable column away from the spring, and a support base is fixedly connected to the top of the processing table.

[0012] This utility model provides a spiral submerged arc welded steel pipe welding clamping and rotating mechanism, which has the following beneficial effects: This invention uses separate motors to drive individual moving blocks, causing the clamping rings to move along with the moving blocks. This allows for the clamping of spiral submerged arc welded steel pipes of varying thicknesses. When the pulleys mounted on the clamping rings contact the spiral submerged arc welded steel pipes, they gradually move towards the fixed shell under the applied force, thereby compressing the springs and preventing excessive clamping force from scratching the exterior of the spiral submerged arc welded steel pipes. By rotating the spiral submerged arc welded steel pipe body, the surface of the spiral submerged arc welded steel pipe slides on the pulleys, achieving a rotational effect.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figures 1-4 As shown, in this embodiment, the spiral submerged arc welded steel pipe welding clamping and rotating mechanism includes a processing table 11. The processing table 11 has two slots 12 on its top sides, and two sliding grooves 13 on both sides of the inner walls of the two slots 12. Motors 14 are installed at both ends of one side of the processing table 11, and support plates 31 are fixedly connected to both ends of one side of the processing table 11. Motors 14 are fixedly installed on the top of both support plates 31. Bidirectional lead screws 15 are installed inside the two slots 12, and moving blocks 16 are installed at two different thread positions of the two bidirectional lead screws 15. Bidirectional lead screws 15 are fixedly connected to the output ends of the two motors 14, and moving blocks 16 are threadedly connected to two different thread positions of the bidirectional lead screws 15. Slider blocks 17 are installed on both sides of the four moving blocks 16, and sliders 17 are fixedly connected to both sides of the moving blocks 16. The external part of the slide block 16 is slidably connected to the inner wall of the slide groove 13. Each of the four moving blocks 16 is provided with a clamping ring 18 at the top. Each of the four clamping rings 18 is provided with a fixed shell 19 in the slot of the clamping ring 18. Each of the multiple fixed shells 19 is provided with a spring 110 inside. Each of the multiple springs 110 is provided with a movable column 112 at one end. The fixed shell 19 is provided with a spring 110 inside. The other end of the spring 110 is fixedly connected to one end of the movable column 112. Each of the multiple movable columns 112 is provided with a pulley 113 at the end away from the spring 110. The external part of the movable column 112 is slidably connected to the inner wall of the fixed shell 19. The end of the movable column 112 away from the spring 110 is rotatably mounted with a pulley 113. The top of the processing table 11 is fixedly connected with a support base 32.

[0020] In this embodiment, when the device is used to clamp the spiral submerged arc welded steel pipe, the spiral submerged arc welded steel pipe can be placed between two sets of clamping rings 18. The distance between the two sets of clamping rings 18 can be adjusted according to the thickness of the spiral submerged arc welded steel pipe. Therefore, the motors 14 can be started to drive their respective moving blocks 16 to move. During the movement, the slider 17 will slide in the slide groove 13, thereby ensuring the stability of the moving block 16 during movement. Therefore, the clamping rings 18 will move with the movement of the moving blocks 16, which can clamp spiral submerged arc welded steel pipes of different thicknesses. When the pulleys 113 installed on the clamping rings 18 come into contact with the spiral submerged arc welded steel pipe, they will gradually move towards the fixed shell 19 with the clamping force, thereby squeezing the spring 110 and avoiding scratches on the outside of the spiral submerged arc welded steel pipe caused by excessive clamping force. When it is necessary to rotate the spiral submerged arc welded steel pipe, the spiral submerged arc welded steel pipe body can be rotated. Therefore, the surface of the spiral submerged arc welded steel pipe will slide on the pulleys 113 to achieve the rotation effect.

[0021] This utility model provides a spiral submerged arc welding steel pipe welding clamping and rotating mechanism, the specific working principle of which is as follows: When using this device to clamp spiral submerged arc welded steel pipes, the pipe can be placed stably in the space formed by two sets of clamping rings 18. The distance between these two sets of clamping rings 18 can then be precisely adjusted according to the actual thickness of the pipe. Specifically, this can be achieved by starting the motors 14, which drive the corresponding moving blocks 16 to move. During the movement of the moving blocks 16, the sliders 17 on them slide smoothly within the pre-set grooves 13. This sliding mechanism effectively ensures the stability of the moving blocks 16 during movement, preventing wobbling, displacement, or other instability. As the moving blocks 16 move stably, the connected clamping rings 18 also move synchronously. With this ingenious design, the device can reliably clamp spiral submerged arc welded steel pipes of varying thicknesses. It is worth mentioning that… A pulley 113 is also installed on the clamping ring 18. When the clamping ring 18 gradually approaches the spiral submerged arc welded steel pipe and applies clamping force, the pulley 113 will contact the surface of the steel pipe and will gradually move slowly towards the fixed shell 19 as the clamping force gradually increases. During this process, the pulley 113 will exert a squeezing effect on the spring 110. This design is of great significance because it can effectively avoid scratches and other damage to the outer surface of the spiral submerged arc welded steel pipe caused by excessive clamping force, thereby ensuring the integrity and quality of the steel pipe surface. In addition, when the spiral submerged arc welded steel pipe needs to be rotated in actual use, the operator can manually rotate the body of the spiral submerged arc welded steel pipe. At this time, the surface of the spiral submerged arc welded steel pipe will slide smoothly on the pulley 113. Through this sliding method, the rotation effect of the spiral submerged arc welded steel pipe can be smoothly achieved to meet different processing or treatment needs. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
