Description

Technical Field

[0001] This utility model relates to the field of high-frequency welded pipe weld seam cooling technology, and in particular to a high-frequency welded pipe weld seam cooling device. Background Technology

[0002] In the field of high-frequency welded pipe production, the weld cooling process plays a decisive role in product quality. With the widespread application of high-frequency welded pipe technology across various industries, the performance requirements for weld cooling devices are becoming increasingly stringent. Traditional cooling methods have revealed numerous problems in meeting the demands of modern high-frequency welded pipe production.

[0003] When existing technical solutions are used, (1) Poor cooling uniformity. The cooling methods are mostly simple single-sided spraying or air cooling, which cannot ensure that all parts of the weld are cooled uniformly. This can easily lead to a large temperature gradient inside the weld, resulting in uneven internal stress, which seriously affects the strength and toughness of the welded pipe and makes the weld prone to defects such as cracks. (2) The lack of precise positioning and adaptive adjustment of the welded pipe makes it difficult to fix the welded pipe according to its diameter when cooling welded pipes of different diameters and wall thicknesses. During the cooling process, the lack of precise positioning makes the welded pipe prone to displacement, which makes it impossible for the weld to be accurately located in the center of the cooling area, further reducing the stability of the cooling effect.

[0004] To address the above problems, this utility model provides a high-frequency welded pipe weld seam cooling device. Utility Model Content

[0010] Furthermore, the support plate and bolts are symmetrically arranged on both sides of the cooling box, and a stable base plate is fixedly connected to the bottom of the support plate, and an anti-slip base is fixedly connected to the bottom of the stable base plate.

[0017] Please see Figure 1-7This utility model provides a technical solution: a high-frequency welded pipe weld cooling device, including a cooling box 1, a cooling mechanism 2, a support mechanism 3 and a fixing mechanism 4. The cooling box 1 is hollow and has a cooling channel 11 inside. The cooling mechanism 2 is fixedly connected to the inside of the cooling box 1, the support mechanism 3 is threadedly connected to the outer surface of the cooling box 1, and the fixing mechanism 4 is fixedly connected to the top of the support mechanism 3.

[0018] The specific setup and function of its cooling mechanism 2, support mechanism 3, and fixing mechanism 4 will be explained below.

[0019] In this embodiment: the cooling mechanism 2 includes a circulating water tank 21 fixedly connected to both sides of the cooling box 1. The interior of the circulating water tank 21 is connected to the interior of the cooling box 1. A cooling component 22 is fixedly connected to the top of the circulating water tank 21. A spiral cooling water pipe 23 is fixedly connected to the top of the cooling component 22. The far end of the spiral cooling water pipe 23 is fixedly connected to the top of the circulating water tank 21 on one side of the cooling box 1. The spiral cooling water pipe 23 is snapped into the interior of the cooling channel 11. Several atomizing nozzles 24 are evenly arranged on the outer surface of the spiral cooling water pipe 23.

[0020] The effects achieved by the above components are as follows: the spiral cooling water pipe 23 tightly surrounds the cooling channel 11, allowing the coolant to be fully close to the weld for cooling. The atomizing nozzle 24 sprays the coolant evenly onto the weld in an atomized form, greatly increasing the contact area between the coolant and the weld, improving cooling efficiency, achieving all-round and uniform cooling of the weld, effectively reducing the internal stress of the weld caused by uneven cooling, and improving the quality of the welded pipe.

[0021] Specifically, the cooling assembly 22 includes a circulating water pump 221 fixedly connected to the top of the circulating water tank 21. A cooler 222 is fixedly connected to the outer surface of the circulating water pump 221. A filter 223 is fixedly connected to the outer surface of the cooler 222. A water pumping pipe 224 is fixedly connected to the outer surface of the filter 223. The far end of the water pumping pipe 224 is fixedly connected to the top of the circulating water tank 21 on the other side of the cooling tank 1.

[0022] The aforementioned components achieve the following effects: the circulating water pump 221 drives the coolant to circulate between the circulating water tank 21, the cooling assembly 22, and the spiral cooling water pipe 23, ensuring continuous cooling. The cooler 222 cools the coolant, keeping it at a low temperature and enhancing the cooling effect.

[0023] Specifically, the cooling mechanism 2 includes a coolant inlet 25 fixedly connected to the top of the cooling tank 1, and a plug 26 threadedly connected to the top of the coolant inlet 25. The cooling mechanism 2 also includes temperature sensors 27 fixedly connected to both ends inside the cooling tank 1.

[0024] The above components achieve the following effects: the coolant replenishment port 25 is fixed to the top of the cooling tank 1 for adding coolant, and its top is threaded to the plug port 26 for sealing; the temperature sensor 27 is fixed at both ends inside the cooling tank 1 to monitor the temperature inside the cooling channel 11 in real time.

[0025] Specifically, the support mechanism 3 includes support plates 31 threaded to both sides of the cooling box 1, and bolts 32 threaded to both sides of the support plates 31. The support plates 31 are threaded to the outer surface of the cooling box 1 by the bolts 32.

[0026] The effect achieved by the above components is that the installation of the support plate 31 can be flexibly adjusted according to the actual use scenario and installation requirements to ensure the stable installation of the cooling box 1.

[0027] Specifically, the support plate 31 and bolts 32 are symmetrically arranged on both sides of the cooling box 1. The bottom of the support plate 31 is fixedly connected to a stable base plate 33, and the bottom of the stable base plate 33 is fixedly connected to an anti-slip base 34.

[0028] The effects achieved by the above components are as follows: the stable base plate 33 enhances the stability of the entire support structure, prevents the support plate 31 from tilting or shaking due to uneven force, effectively prevents the equipment from shifting due to vibration, external force collision and other factors during operation, and ensures the stability of the cooling device during operation.

[0029] Specifically, the fixing mechanism 4 includes a positioning ring 41 fixedly connected to the top edge of the stabilizing base plate 33. The positioning ring 41 is symmetrically arranged at both ends of the cooling box 1, and the center point of the positioning ring 41 and the cooling box 1 are on the same axis.

[0030] The effect achieved by the above components is to provide an initial center positioning reference for the welded pipe during the transportation process, ensure that the welded pipe can accurately enter the cooling channel 11, and place the weld in the center of the cooling area, thereby improving the consistency and stability of the cooling effect.

[0031] Specifically, the positioning ring 41 is threaded with adjusters 42 on both sides, and the bottom of the adjusters 42 is rotatably connected with bearings 43. The outer surface of the bearings 43 is fixedly connected with steel pipe positioning plates 44, and the outer surface of the bearings 43 is fitted into the interior of the steel pipe positioning plates 44. The steel pipe positioning plates 44 and adjusters 42 are symmetrically arranged on both sides of the positioning ring 41.

[0032] The effect achieved by the above components is that the operator can adjust the position of the steel pipe positioning plate 44 by rotating the adjuster 42 according to the different diameter of the welded pipe, and accurately position the welded pipe from both sides to ensure that the welded pipe maintains a stable position during the cooling process and improves the cooling effect.

[0033] Working principle: When the high-frequency welded pipe enters the cooling device, the fixing mechanism 4 first accurately positions the welded pipe. According to the diameter of the welded pipe, the operator adjusts the regulator 42 so that the steel pipe positioning plate 44, with the assistance of the bearing 43, fits tightly against the outer wall of the welded pipe from both sides, ensuring that the center of the welded pipe is consistent with the center of the cooling box 1 and the center of the cooling channel 11, and accurately enters the cooling channel 11.

[0034] Cooling mechanism 2 starts working, and circulating water pump 221 starts to draw out coolant from circulating water tank 21. The coolant is first cooled by cooler 222, and then impurities are removed by filter 223 before flowing into spiral cooling water pipe 23. Atomizing nozzles 24 on spiral cooling water pipe 23 atomize and spray coolant evenly onto the weld seam to achieve cooling of the weld seam. Excess coolant flows back into cooling box 1 and re-enters circulating water pump 221 through circulating water tank 21 connected to the inside of cooling box 1, forming a circulating cooling system.

[0035] During the cooling process, the temperature sensor 27 monitors the temperature in the cooling channel 11 in real time, adjusts the flow rate of the circulating water pump 221, controls the circulation speed of the coolant, and adjusts the cooling intensity of the cooler 222 to ensure that the coolant temperature is suitable. When the coolant level drops due to loss, coolant can be added through the coolant replenishment port 25, and the plug port 26 ensures that the coolant will not leak.

[0036] Throughout the process, the support mechanism 3 securely installs the cooling box 1 using the support plate 31 and bolts 32, while the stable base plate 33 and anti-slip base 34 ensure that the equipment will not shift during operation, providing a stable foundation for the normal operation of the cooling mechanism 2 and the fixing mechanism 4.
