Description

Technical Field

[0001] This utility model relates to the technical field of welding cooling devices, and in particular to a welding cooling device for a high-frequency welded pipe unit. Background Technology

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by rolling steel plates or strips into shape and then welding them. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications. It has a wide range of applications in production and daily life. In the production process of welded pipe, in order to prevent the welded pipe from oxidizing at high temperatures and improve the quality of the welded pipe, it is often necessary to perform cooling treatment.

[0003] In existing technologies, coolant is typically sprayed onto the welded pipe for cooling. For example, Chinese utility model patent CN220902159U describes a method where, after cooling the high-frequency welded pipe, the coolant, under its own gravity, enters a recovery hopper and then flows through a recovery pipe into a filter. There, it is filtered by a filter screen, filter plate one, and filter plate two, removing impurities from the coolant. Impurities are collected on one side of the filter's inner cavity through a discharge hole. During discharge, the impurities are simply opened to release them. The filtered coolant, under the action of a return pump, returns to the collection tank through the return pipe, allowing for recycling. This solves the problem of inconvenient coolant recycling in traditional cooling devices. The problem of consuming a large amount of coolant for cooling high-frequency welded pipes is that spraying coolant can only contact the sides and top of the pipe when the spray nozzle is positioned directly above it. This makes it difficult to cool the bottom of the pipe. Cooling the bottom of the pipe can only be achieved indirectly through the sides and top, which not only reduces the overall cooling efficiency and requires longer spraying time, increasing water and energy consumption, but also causes uneven cooling, potentially leading to bending, twisting, and other deformations. This is especially problematic for the heat-affected zone after welding and may even cause weld cracking. Therefore, we propose a welding cooling device for high-frequency welded pipe units.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a welding cooling device for a high-frequency welded pipe unit, including a cooling box 1. The left and right surfaces of the cooling box 1 are each provided with a through groove 2 communicating with the interior of the cooling box 1. A spray plate 3 is provided on the top of the cooling box 1 to spray and cool the welded pipe. Two mounting sleeves 4 are fixedly connected to the inner wall of the cooling box 1. Mounting rings 5 ​​are rotatably mounted inside each mounting sleeve 4. The surfaces of the two mounting rings 5 ​​that are far apart from each other extend outwards from the two mounting sleeves 4. Two first mounting plates 6 are fixedly connected to the inner wall of the mounting rings 5. Rollers 7 are rotatably connected between the two first mounting plates 6. The roller 7 reduces the resistance of the welded pipe during linear movement and can drive the welded pipe to rotate around its own axis. The rotation direction of the roller 7 is consistent with the movement direction of the welded pipe. The outer surface of the mounting ring 5 is fitted with a first synchronous wheel 8. Two second mounting plates 9 are fixedly connected to the rear surface of the cooling box 1. The second mounting plates 9 are equipped with rotating components. By using the rotation of the mounting ring 5 in conjunction with the setting of the roller 7, the welded pipe can be driven to rotate during the cooling process. At the same time, the rotation direction of the roller 7 is consistent with the forward direction of the welded pipe. Therefore, the resistance of the welded pipe during the movement can be reduced by using the roller 7, which can ensure the uniformity and efficiency of the welded pipe during the cooling process.

[0024] Furthermore, the rotating assembly includes a first drive shaft 10, which is rotatably connected between two second mounting plates 9. Two second synchronous pulleys 11 are fitted onto the outer surface of the first drive shaft 10. A clearance hole 23 extending into the interior of the cooling box 1 is provided on the outer surface of the cooling box 1. A first synchronous belt 12 is fitted between the first synchronous pulley 8 and the second synchronous pulleys 11. A drive motor 13 is fixedly connected to the rear surface of the cooling box 1. The output end of the drive motor 13 is fixedly connected to the first drive shaft 10 via a coupling. Two third mounting plates 14 are fixedly connected to the rear surface of the cooling box 1. A second drive shaft 15 is rotatably connected between the two third mounting plates 14. The right end of the second drive shaft 15 rotatably extends through the right side surface of the right third mounting plate 14. The second drive shaft 15 and the first drive shaft... The outer surface of the cooling box 10 is fitted with a third synchronous pulley 16. A second synchronous belt 17 is fitted between the two third synchronous pulleys 16. A bevel gear 18 is fixedly connected to the right end of the second transmission shaft 15. Two rotating sleeves 19 are fixedly connected to the right side surface of the cooling box 1. A third transmission shaft 20 is rotatably fitted inside the two rotating sleeves 19. A bevel gear 18 is also fixedly connected to the rear end of the third transmission shaft 20. The two bevel gears 18 mesh with each other. A cam 21 is fixedly connected to the front end of the third transmission shaft 20. A groove 22 is opened on the surface of the cam 21. By using the setting of the cam 21 and the groove 22, while controlling the rotation of the welded pipe, the welded pipe can also be intermittently driven to move, thereby realizing automated cooling of the long welded pipe and reducing the labor intensity and workload of the workers.

[0025] Among them, the two bevel gears 18 can be replaced with right-angle reducers to reduce the frequency of cam 21 rotation. The cooling box 1 is equipped with a cooling component and a filter component. The filter component is connected to the cooling component, and the cooling component is connected to the spray plate 3. The cooling component, filter component and spray plate 3 are all existing structures. For details, please refer to patent publication number CN220902159U. They will not be described in detail here.

[0026] Working principle: When cooling the welded pipe, cooling water is first transferred to the spray plate 3 through the cooling assembly. Then, the coolant is sprayed onto the welded pipe through the spray plate 3. At this time, the drive motor 13 drives the first transmission shaft 10 to rotate. When the first transmission shaft 10 rotates, it will synchronously drive the second synchronous pulley 11 and the third synchronous pulley 16 to rotate. When the second synchronous pulley 11 rotates, it will cooperate with the first synchronous belt 12 to drive the first synchronous pulley 8 to rotate. In turn, the first synchronous pulley 8 drives the mounting ring 5 to rotate. When the mounting ring 5 rotates, it will drive the internal first mounting plate 6 and roller 7 to rotate. Since the rotation direction of the mounting ring 5 is different from that of the roller 7, the rotation direction of the first mounting plate 6 and the roller 7 will rotate. Since roller 7 can rotate in different directions, the friction between roller 7 and welded pipe is relatively large at this time. Thus, roller 7 drives welded pipe to rotate. When welded pipe rotates, coolant can be sprayed evenly on the surface of welded pipe. At the same time, when the third synchronous pulley 16 rotates, it can cooperate with the second synchronous belt 17 to drive the second transmission shaft 15 to rotate. When the second transmission shaft 15 rotates, it uses the cooperation of two bevel gears 18 to drive the third transmission shaft 20 to rotate. Then, the third transmission shaft 20 drives the cam 21 to rotate. After the cam 21 rotates, the inner wall of the groove 22 intermittently contacts the welded pipe. Thus, the intermittent rotation of the cam 21 drives the welded pipe to move forward intermittently.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
