[0002] A straight pipe is a pipeline mainly used for transporting liquids and gases. Straight pipes usually have a larger diameter and smaller valves.
[0003] Straight pipe welding is an important process for connecting two or more straight pipes. Straight pipe welding usually trims the straight pipe into the required size according to the diameter and length to be connected, embeds the trimmed straight pipe into the corresponding ports of the welding joint, and selects a suitable welding tool according to the material and thickness of the straight pipe, so as to carry out the welding work of the straight pipe.

Detailed Embodiments
[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] As Figures 1 to 4 shown, a butt-welding tooling for straight pipes according to an embodiment of the present utility model includes a bottom plate 1; two sliding grooves 11 are formed at the top of the bottom plate 1; a lead screw 12 is installed in the middle of the sliding groove 11; one end of the lead screw 12 is rotatably connected to the end of the sliding groove 11, and the other end of the lead screw 12 penetrates through the side wall of the bottom plate 1; a driving motor 14 is fixedly connected to the end of the lead screw 12; a square nut 13 is threadedly connected to the middle of the lead screw 12; the square nut 13 is slidably connected in the middle of the sliding groove 11; a fixing plate 15 is fixedly connected to the top of the square nut 13; the two fixing plates 15 are arranged oppositely; a supporting plate 16 is fixedly connected to the top of the fixing plate 15; the top of the supporting plate 16 is arc-shaped; the supporting plate 16 is arranged at one end of the fixing plate 15; two protective boxes 17 are fixedly connected to the side wall of the bottom plate 1; the protective boxes 17 are fixedly connected to the outside of the corresponding driving motors 14; a fixing component is installed on the top of the fixing plate 15; during work, the middle parts of two straight pipes to be welded together are respectively placed on two oppositely arranged supporting plates 16, the middle parts of the straight pipes are supported by the supporting plates 16, and the welded ends of the straight pipes are placed in the middle of the fixing component for fixation. After the driving motor 14 is powered on and started, the driving motor 14 is controlled to rotate. During the rotation of the driving motor 14, the lead screw 12 rotates in the middle of the sliding groove 11. When the lead screw 12 rotates, the square nut 13 drives the fixing plate 15 to move, so that the welded ends of the two oppositely arranged straight pipes are aligned, and thus the butt-welding work of the straight pipes is carried out. After the two straight pipes are welded, the straight pipes are drawn out from the middle of the fixing component. In the welding work area, the driving motor 14 is protected by the protective box 17 to prevent the outside air and objects from directly contacting or colliding with the driving motor 14. Through the above structure, the welded ends of the two straight pipes are kept in a horizontal state, which can enable the straight pipes to achieve precise butt-joint during welding. When the two straight pipes are in a horizontal state, the deformation or deviation of the pipes caused by gravity or other external forces is reduced, effectively reducing the problems of deviation in position during the welding process, such as the appearance of weld seams or welding inclination, enabling the two straight pipes to form uniform and continuous weld seams, enabling the welding material to be evenly distributed at the weld seams, reducing the appearance of too wide or too narrow weld seams, and thus effectively improving the strength and tightness of the weld seams.
[0024] As Figures 1 to 4As shown, the fixing component includes a fixing frame 2; the middle part of the fixing frame 2 is arc-shaped; the fixing frame 2 is fixedly connected to the top of the fixing plate 15; the fixing frame 2 and the support plate 16 are arranged oppositely; a hydraulic rod 21 is installed on the top of the fixing frame 2; the output end of the hydraulic rod 21 penetrates through the top of the fixing frame 2; the output end of the hydraulic rod 21 is fixedly connected to a pressing plate 22; the pressing plate 22 is arc-shaped; the pressing plate 22 is elastically arranged; two first springs 23 are fixedly connected to the middle of the pressing plate 22; the end of the first spring 23 is fixedly connected to an elastic plate 24; during operation, the welded end of the straight-through pipe is passed through the middle of the fixing frame 2 and placed in the arc-shaped groove in the middle of the fixing frame 2. After the hydraulic rod 21 is powered on and started, the output end of the hydraulic rod 21 is controlled to move downward. During the downward movement of the output end of the hydraulic rod 21, first, it contacts the surface of the straight-through pipe through the two elastic plates 24. During the continuous downward pressing of the hydraulic rod 21, the first spring 23 undergoes elastic contraction, and the flexible material of the pressing plate 22 elastically bends according to the size of the straight-through pipe. The two elastic plates 24 closely fit the middle of the straight-through pipe, and the welded end of the straight-through pipe is clamped and fixed by the pressing plate 22. Through the above structure, the two straight-through pipes can maintain an accurate docking position during the welding process, effectively reducing the deviation caused by movement or vibration during docking. During the welding process, due to the action of high temperature and welding stress, the pipe is prone to deformation. Clamping the welded end of the straight-through pipe can reduce the movement and deformation of the pipe during the welding process, effectively reducing the problems of weld cracking or lack of fusion caused by position deviation and welding deformation during the welding process, and effectively improving the overall accuracy of the straight-through pipe welding.
[0025] As Figures 1 to 4As shown in the figure, a collection box 3 is fixedly connected to the top of the bottom plate 1; the collection box 3 is arranged between two fixed plates 15; both sides of the bottom of the collection box 3 are inclined; two fixing grooves 31 are formed in the side wall of the bottom plate 1; the two fixing grooves 31 are formed on both sides of the collection box 3; a dust suction pipe 32 is installed in the middle of the fixing groove 31; the dust suction pipe 32 is U-shaped; a connecting pipe 33 is fixedly connected to the middle of the dust suction pipe 32; the end of the connecting pipe 33 is fixedly connected to a vacuum cleaner 34; the vacuum cleaner 34 is fixedly connected to the side wall of the bottom plate 1; two dust suction grooves 35 are formed in the middle of the dust suction pipe 32; the two dust suction grooves 35 penetrate through the side wall of the collection box 3; during operation, after the ends of the two straight pipes are aligned, the welding position is at the top of the collection box 3. During the welding process of the straight pipes, a large amount of debris will be generated. When the debris falls, it enters the inside of the collection box 3 for collection. At this time, the vacuum cleaner 34 is powered on and started. Negative pressure air flow is generated inside the vacuum cleaner 34. The negative pressure air flow sucks in the external air flow through the dust suction grooves 35. The debris collected inside the collection box 3 is sucked into the dust suction pipe 32 through the dust suction grooves 35. The debris inside the dust suction pipe 32 enters the vacuum cleaner 34 through the connecting pipe 33 for centralized collection. Through the above structure, the metal debris and slag generated during the welding process of the straight pipes can be collected in time, reducing the problems of wear and blockage of the equipment caused by the welding debris scattered on the working area. Collecting the debris and slag in time can reduce the direct contact between the debris and the equipment, thereby reducing the problem of equipment wear and reducing the operation time required for additional cleaning of the working area after welding is completed.
[0026] As Figure 2 shown, a storage groove 4 is formed at the end of the fixed plate 15; the storage groove 4 is formed on the side close to the fixed frame 2; a second spring 41 is fixedly connected to the middle of the storage groove 4; a sliding rod 42 is fixedly connected to the end of the second spring 41; a buffer head 43 is fixedly connected to the end of the sliding rod 42; during operation, after the two straight pipes are fixed, the two fixed plates 15 are moved towards the middle. When the fixed plate 15 is moving, first, the end of the buffer head 43 contacts the side wall of the collection box 3, absorbing the impact force during the movement of the fixed plate 15. When the fixed plate 15 continues to move, the buffer head 43 is squeezed, causing the sliding rod 42 to slide into the storage groove 4. The sliding rod 42 is stored through the storage groove 4. At the same time, the second spring 41 retracts as the sliding rod 42 moves inward. When the welding of the straight pipes is completed, the fixed plate 15 moves back to its original position. When the buffer head 43 is not under pressure, it is elastically reset by the second spring 41. Through the above structure, the impact force can be absorbed and dispersed during the alignment and movement of the straight pipes, effectively enabling the two straight pipes to be aligned smoothly and precisely during welding, reducing the docking deviation caused by movement or vibration, effectively improving the accuracy and consistency of the welded joints, reducing the impact generated when the ends of the two straight pipes are butted, and reducing the damage to the straight pipes.
[0027] AsFigure 2 As shown, a plurality of buffer plates 5 are fixedly connected to the bottom of the bottom plate 1; the buffer plates 5 are respectively arranged at the four corners of the bottom of the bottom plate 1; a suction cup 51 is fixedly connected to the bottom of the buffer plate 5; during operation, when the bottom plate 1 is placed on a plane, it first contacts the plane through the suction cup 51. When the suction cup 51 contacts the plane, it is fixed by suction. When the straight-through pipe is welded and generates vibrations, the vibrations are absorbed by the buffer plate 5 and the suction cup 51 and transmitted to the plane, so that the straight-through pipe remains stable during welding. Through the above structure, during the welding process of the straight-through pipe, the vibrations generated during welding can be effectively absorbed and dispersed, and the stability during the welding process of the straight-through pipe can be maintained. The bottom plate 1 is firmly fixed on the platform through the adsorption force of the suction cup 51, further enhancing the stability during the welding process and reducing the welding deviation caused by movement or vibration.
[0028] As Figure 1 and Figure 4 shown, two baffle plates 6 are fixedly connected to the top of the collection box 3; the two baffle plates 6 are arranged oppositely; the baffle plates 6 are arc-shaped; during operation, when the straight-through pipe is being welded, the baffle plates 6 block the flying debris, so that the debris collides with the side wall of the baffle plate 6 and then slides into the interior of the collection box 3. Through the above structure, the flying debris generated during the welding process can be directed, reducing the debris scattered everywhere in the working area, improving the collection efficiency of the flying debris, and reducing the scratches and damages caused by the flying objects to the surrounding equipment and tools.
[0029] As Figure 1 , Figure 3 , Figure 4 shown, a rubber pad 7 is fixedly connected to the top of the support plate 16; a rubber pad 7 is fixedly connected to the middle of the fixing frame 2; during operation, when the straight-through pipe is placed on the support plate 16 and the fixing frame 2, it first contacts the surface of the straight-through pipe through the rubber pad 7. Through the above structure, it can be closely attached to the straight-through pipe. Through the above structure, it has good elasticity and buffering performance, and can effectively reduce the stress and vibration generated by the self-weight of the straight-through pipe, the flow of the medium or the change of the external environment. A certain protection and stability can be formed between the rubber pad 7, the straight-through pipe and the supporting surface.
[0030] During operation, the middle parts of two straight pipes to be welded together are respectively placed on two opposite support plates 16. The support plates 16 support the middle parts of the straight pipes. One end of the straight pipe to be welded is placed in the middle of the fixing component for fixing. After the driving motor 14 is powered on, it is started, and the driving motor 14 is controlled to rotate. During the rotation of the driving motor 14, the lead screw 12 rotates in the middle of the sliding groove 11. When the lead screw 12 rotates, the square nut 13 drives the fixing plate 15 to move, aligning the welding ends of the two opposite straight pipes, so as to perform the welding work on the straight pipes. After the two straight pipes are welded, the straight pipes are drawn out from the middle of the fixing component. In the welding work area, the driving motor 14 is protected by the protection box 17 to prevent the outside air and objects from directly contacting or colliding with the driving motor 14. One welded end of the straight pipe passes through the middle of the fixing frame 2 and is placed in the arc groove in the middle of the fixing frame 2. After the hydraulic rod 21 is powered on, it is started, and the output end of the hydraulic rod 21 is controlled to move downward. During the downward movement of the output end of the hydraulic rod 21, first, it contacts the surface of the straight pipe through two elastic plates 24. During the continuous downward pressing of the hydraulic rod 21, the first spring 23 generates elastic contraction, and the flexible material of the pressing plate 22 elastically bends according to the size of the straight pipe. The two elastic plates 24 closely fit the middle of the straight pipe, and the welding end of the straight pipe is clamped and fixed by the pressing plate 22. After the two ends of the straight pipes are aligned, the welding position is at the top of the collection box 3. A large amount of debris will be generated during the welding process of the straight pipes. When the debris falls, it enters the inside of the collection box 3 for collection. At this time, the vacuum cleaner 34 is powered on and started. Negative pressure air flow is generated inside the vacuum cleaner 34. The negative pressure air flow sucks the external air through the dust suction groove 35. The debris collected inside the collection box 3 is sucked into the dust suction pipe 32 through the dust suction groove 35. The debris inside the dust suction pipe 32 enters the vacuum cleaner 34 through the connecting pipe 33 for centralized collection. After the two straight pipes are fixed, the two fixing plates 15 are moved towards the middle. When the fixing plates 15 move, first, the end of the buffer head 43 contacts the side wall of the collection box 3, absorbing the impact force during the movement of the fixing plates 15. When the fixing plates 15 continue to move, the buffer head 43 is squeezed, causing the sliding rod 42 to slide into the storage groove 4, and the sliding rod 42 is stored through the storage groove 4. At the same time, the second spring 41 retracts as the sliding rod 42 moves inward. After the straight pipes are welded, the fixing plates 15 move back to their original positions. When the buffer head 43 is not under pressure, it is elastically reset by the second spring 41. When the bottom plate 1 is placed on a plane, first, it contacts the plane through the suction cup 51. When the suction cup 51 contacts the plane, it is fixed by suction. When the straight pipes vibrate during welding, the vibration is absorbed by the buffer plate 5 and the suction cup 51 and transmitted to the plane, keeping the straight pipes stable during welding. When the straight pipes are being welded, the debris is blocked by the baffle 6 from splashing, and the debris collides with the side wall of the baffle 6 and then slides into the collection box 3. When the straight pipes are placed on the support plates 16 and the fixing frame 2, first, they contact the surface of the straight pipes through the rubber pads 7.
