Description

Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, and specifically relates to a cooling device for steel pipe processing. Background Technology

[0002] Steel pipe processing typically follows a process that transforms raw materials (standard-length steel pipes) into the final required parts or components. In steel pipe processing, cooling devices are crucial, as they directly affect product quality (such as mechanical properties, metallographic structure, and dimensional accuracy) and production efficiency. After steel pipes are hot-rolled (such as through continuous rolling processes) to a high temperature of approximately 900-1000°C, they need to be cooled to room temperature for subsequent finishing and inspection.

[0003] Existing cooling devices for steel pipe processing (thermomechanical control process) combine controlled rolling and controlled cooling in steel pipe production, significantly improving the strength and toughness of steel pipes without adding alloying elements. A large number of laminar flow nozzles are used to form a uniform and stable water curtain on the steel pipe surface, ensuring even cooling and preventing the formation of a fine water mist due to uneven stress. The cooling intensity is between that of air cooling and water cooling, allowing for more precise control. However, in actual use, the limitations of traditional fixed-point spraying make it difficult for the cooling medium to evenly cover the entire outer surface of the steel pipe, potentially leading to localized unevenness and deformation due to cooling dead zones. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a cooling device for steel pipe processing, which allows the nozzle to both revolve around the steel pipe and move radially back and forth. This dynamic cooling mode breaks the limitations of traditional fixed-point spraying, and the cooling medium can cover the entire outer surface of the steel pipe, including areas that are difficult to cool evenly in the traditional way, effectively avoiding the problem of uneven local structure and deformation caused by cooling dead corners.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a cooling device for steel pipe processing, including a cooling box, two L-shaped support plates symmetrically distributed around the vertical center of the cooling box are fixedly installed inside the cooling box, a rotating cylinder is rotatably installed in the middle of each L-shaped support plate, and multiple sliding cylinders evenly distributed around the transverse center of each rotating cylinder are fixedly installed on the inner wall of each rotating cylinder, a sliding rod is slidably installed inside each sliding cylinder, and a mounting seat is fixedly installed at the end of each sliding rod, a water supply pipe is fixedly installed between two adjacent mounting seats, and multiple nozzles facing the transverse center of the rotating cylinder are fixedly installed on the outer arc surface of the water supply pipe.

[0006] As a further improvement of this utility model, a water storage pipe is fixedly installed inside the cooling box, and a telescopic pipe is installed between the water supply pipe and the water storage pipe. A water inlet pipe is installed between the water storage pipe and the cooling box. An adjusting screw is rotatably installed inside the slide cylinder. The adjusting screw is threadedly connected to the adjacent slide rod. A bevel gear is fixedly sleeved on the end of the adjusting screw away from the lateral center of the rotating cylinder. A bevel tooth ring is fixedly installed on the L-shaped support plate. The bevel gear is meshed with the adjacent bevel tooth ring. Two drive rods are rotatably installed between the cooling box and the L-shaped support plate, symmetrically distributed around the vertical center of the cooling box. Two flat gears are fixedly sleeved on the outer arc surface of the drive rods, symmetrically distributed around the vertical center of the cooling box. Two flat tooth rings are fixedly sleeved on the outer arc surface of the rotating cylinder, symmetrically distributed around the vertical center of the cooling box. The flat gears are meshed with the adjacent flat tooth rings.

[0007] As a further improvement of this utility model, a drive box is fixedly installed on the outside of the cooling box. Inside the drive box, two rotating shafts are symmetrically distributed about the vertical center of the drive box. The rotating shafts are fixed to adjacent drive rods by couplings. Worm gears are fixedly sleeved on the outer arc surface of the rotating shafts. Inside the drive box, two U-shaped seats are fixedly installed symmetrically distributed about the vertical center of the drive box. Worms are rotatably installed inside the U-shaped seats. The worms are meshed with adjacent worm gears. A dual-axis motor is fixedly installed in the middle of the drive box. The output shafts of the dual-axis motor are fixed to adjacent worms by couplings.

[0008] As a further improvement of this utility model, two guide rails are fixedly installed on both sides of the cooling box, symmetrically distributed around the vertical center of the cooling box. Two sliding frames are slidably installed between two adjacent guide rails, symmetrically distributed around the horizontal center of the cooling box. Multiple rollers are rotatably installed inside each sliding frame. Two electric push rods are fixedly installed on the outside of the cooling box, symmetrically distributed around the horizontal center of the cooling box. The telescopic ends of the electric push rods are connected and fixed to the adjacent sliding frames.

[0009] As a further improvement of this utility model, a water tank is fixedly provided on the lower side of the cooling box, and multiple support legs are fixedly provided on the lower side of the water tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, the electric push rod precisely controls the distance between the upper and lower rollers, enabling rapid adaptation to steel pipes of different diameters. This adaptive adjustment mechanism significantly improves the equipment's versatility, allowing it to handle various product specifications without changing molds, greatly enhancing the production line's flexibility. Driven by a dual-axis motor, worm gear, and gear mechanism, the nozzle performs complex compound movements: it revolves around the steel pipe and moves radially back and forth. This dynamic cooling mode breaks the limitations of traditional fixed-point spraying, allowing the cooling medium to cover the entire outer surface of the steel pipe, including areas that are difficult to cool evenly using traditional methods, effectively avoiding localized unevenness and deformation caused by cooling dead zones.

[0011] Secondly, the uniformity of cooling directly determines the final quality of the steel pipe. This device ensures that the contact time and impact angle between the cooling medium and various parts of the steel pipe surface are more uniform by moving the nozzle in three-dimensional space. This uniform cooling is to obtain a fine and consistent metal structure, thereby significantly improving the comprehensive mechanical properties of the steel pipe, such as yield strength, tensile strength and low-temperature impact toughness.

[0016] like Figure 2 As shown, the system includes a cooling box 103. Inside the cooling box 103, two L-shaped support plates 201 are fixedly arranged symmetrically about the vertical center of the cooling box 103. A rotating cylinder 202 is rotatably arranged in the middle of each L-shaped support plate 201. Multiple sliding cylinders 203 are fixedly arranged on the inner wall of each rotating cylinder 202, evenly distributed about the transverse center of the rotating cylinder 202.

[0017] like Figure 2 , 3 As shown in Figure 4, a water storage pipe 207 is fixedly installed inside the cooling tank 103. A telescopic pipe 209 is installed between the water supply pipe 205 and the water storage pipe 207. A water inlet pipe 208 is installed between the water storage pipe 207 and the cooling tank 103. An adjusting screw 210 is rotatably installed inside each of the sliding cylinders 203. The adjusting screw 210 is threadedly connected to adjacent sliding rods. A bevel gear 211 is fixedly fitted at the end of the adjusting screw 210 away from the lateral center of the rotating cylinder 202. A bevel gear ring 212 is fixedly installed on each of the L-shaped support plates 201. Wheel 211 meshes with adjacent bevel gear ring 212 respectively; two drive rods 213 are rotatably arranged between cooling box 103 and L-shaped support plate 201, symmetrically distributed around the vertical center of cooling box 103. Two flat gears 214 are fixedly sleeved on the outer arc surface of drive rod 213, symmetrically distributed around the vertical center of cooling box 103. Two flat gear rings 215 are fixedly sleeved on the outer arc surface of rotating cylinder 202, symmetrically distributed around the vertical center of cooling box 103. The flat gears 214 mesh with adjacent flat gear rings 215 respectively.

[0018] like Figure 4As shown, a drive box 301 is fixedly installed on the outside of the cooling box 103. Inside the drive box 301, two rotating shafts 302 are symmetrically distributed about the vertical center of the drive box 301. The rotating shafts 302 are fixed to the adjacent drive rods 213 by couplings. Worm gears 303 are fixedly sleeved on the outer arc surface of the rotating shafts 302. Inside the drive box 301, two U-shaped seats 304 are fixedly installed about the vertical center of the drive box 301. Worms 305 are rotatably installed inside the U-shaped seats 304. The worms 305 are meshed with the adjacent worm gears 303. A dual-axis motor 306 is fixedly installed in the middle of the drive box 301. The output shafts of the dual-axis motor 306 are fixed to the adjacent worms 305 by couplings.

[0019] like Figure 1 , 2 As shown, two guide rails 104 are fixedly installed on both sides of the cooling box 103, symmetrically distributed around the vertical center of the cooling box 103. Two sliding frames 105 are slidably installed between two adjacent guide rails 104, symmetrically distributed around the horizontal center of the cooling box 103. Multiple rollers 107 are rotatably installed inside each sliding frame 105. Two electric push rods 106 are fixedly installed on the outside of the cooling box 103, symmetrically distributed around the horizontal center of the cooling box 103. The telescopic ends of the electric push rods 106 are connected and fixed to the adjacent sliding frames 105.

[0020] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a water tank 101 is fixedly installed on the lower side of the cooling box 103, and multiple support legs 102 are fixedly installed on the lower side of the water tank 101.

[0021] In use, the operation of the two electric push rods 106 is controlled, which in turn drives the telescopic ends of the electric push rods 106 on the upper and lower sides to extend synchronously, thereby driving the two sliding frames 105 to slide between the guide rails 104, thereby driving the sliding frames 105 on the upper and lower sides to move closer to the transverse center of the cooling box 103, thereby driving the rollers 107 on the upper and lower sides to move closer together, and adjusting the distance between the rollers 107 on the upper and lower sides so that the distance between the rollers 107 on the upper and lower sides can be adapted to the steel pipe to be cooled, so that the steel pipe to be cooled can be in the middle of the cooling box 103 with the cooperation of the rollers 107 on the upper and lower sides. Then, the dual-axis motor 306 is controlled to run, causing its output shafts to rotate in both directions. This, in turn, drives the worm gear 305 connected to it to rotate. Through the meshing relationship between the worm gear 305 and the worm wheel 303, the shaft 302 containing the worm wheel 303 rotates, causing both shafts 302 to rotate synchronously and in the same direction in both directions. This, in turn, causes the drive rods 213 on both sides to rotate synchronously and in the same direction in both directions in both directions, thus driving the drive rods... The spur gear 214, which is fixedly mounted on the outer arc surface of 213, rotates, thereby driving the spur gear 214 to rotate synchronously and in the same direction. During this process, the meshing relationship between the spur gear 214 and the spur gear ring 215 drives the rotating drum 202 where the spur gear ring 215 is located to rotate in both directions, thereby driving multiple water pipes 205 to rotate in both directions around the transverse center of the cooling box 103, so that the water pipes 205 drive multiple nozzles 206 installed on them to rotate in both directions around the transverse center of the cooling box 103. During the reciprocating rotation of the drum 202, the meshing relationship between the bevel ring 212 and the bevel gear 211 drives the adjusting screw 210 where the bevel gear 211 is located to rotate. Then, the thread relationship between the adjusting screw 210 and the slide rod drives the slide rod and the slide drum 203 to slide back and forth. This causes multiple water pipes 205 to continuously approach or move away from the transverse center of the cooling box 103 during the reciprocating rotation around the transverse center of the cooling box 103. As a result, the water pipes 205 drive multiple nozzles 206 installed on them to continuously approach or move away from the transverse center of the cooling box 103 during the reciprocating rotation around the transverse center of the cooling box 103. Then, the external water source is connected to the inlet pipe 208, and the inlet pipe 208 delivers cooling water into the storage pipe 207, filling the storage pipe 207 with cooling water. The storage pipe 207 then enters each water supply pipe 205 through the telescopic pipe 209, and sprays out through the nozzles 206 on the water supply pipe 205. As each water supply pipe 205 drives the multiple nozzles 206 installed on it to rotate back and forth around the transverse center of the cooling box 103, they continuously approach or move away from the transverse center of the cooling box 103, so that the nozzles can spray cooling water onto the steel pipe between the upper and lower rollers 107, thereby facilitating the cooling of the steel pipe during the processing.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
