Description

Technical Field

[0001] This utility model relates to the field of seamless steel pipe production, specifically a cooling device for the production of thick-walled seamless steel pipes. Background Technology

[0002] Seamless steel pipes are steel pipes made from a single piece of metal without any seams on their surface. Based on the production method, seamless pipes are classified as hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and jacking pipes. Depending on their application, they are classified as thick-walled pipes and thin-walled pipes. Seamless steel pipes are mainly used as drilling pipes for oil and geological processes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation. The production process of seamless steel pipes requires a cooling step. The cooling method varies depending on the material and geometry of the steel pipe. For most steel grades, natural cooling is sufficient to meet requirements. For certain special-purpose steel pipes, specific cooling methods and regimes are necessary to ensure the required microstructure and physical and mechanical properties. For example, thick-walled austenitic stainless steel pipes require final rolling at a certain temperature, followed by rapid water cooling for solution treatment, and then natural cooling on a cooling bed.

[0003] Currently, the cooling device for seamless steel pipes in existing technology includes a cooling assembly and a driving assembly. The cooling assembly includes a base, a water inlet, and a limiting assembly, while the driving assembly includes a rotating assembly and a top-loading assembly. The base includes a fixed base, a pump body, and a drain pipe. A water-cooling tank is provided above the fixed base, and the seamless steel pipe body is placed inside the water-cooling tank. The seamless steel pipe body is cooled by immersing it in the water-cooling tank.

[0004] However, existing cooling devices for seamless steel pipe production directly immerse the steel pipe in a water tank. Due to the long length of the steel pipe and the small water capacity and lack of fluidity inside, the heat cannot be quickly removed from the pipe, which reduces the cooling efficiency of the thick-walled steel pipe and negatively affects its mechanical properties. Therefore, a cooling device for thick-walled seamless steel pipe production is proposed to address the above problems. Utility Model Content

[0014] This utility model provides a cooling device for the production of thick-walled seamless steel pipes. The device involves placing the steel pipe between two connecting plates; then activating a first electric telescopic rod, which clamps the steel pipe to the connecting plates, allowing a limiting post to enter and limit its movement.

The screw then moves a moving block, which, through a moving plate, connecting rod, and the first electric telescopic rod, moves the connecting plate, thereby drawing the steel pipe into a water tank for further cooling. This improves the cooling speed of the thick-walled steel pipe and reduces the impact on its mechanical properties.

After the steel pipe is inserted into the water tank, the second electric telescopic rod is activated. The second electric telescopic rod drives the arc-shaped clamping plate to fix and clamp the steel pipe, reducing the shaking of the steel pipe and keeping the steel pipe stable.

The head 116 rotates to spray water, ensuring even water distribution inside the steel pipe. Simultaneously, the drive motor 103 is activated, driving the drive wheel 104 to rotate. The drive wheel 104 drives the driven wheel 106 to rotate via the transmission belt 105. The driven wheel 106 and the drive wheel 104 drive the screw 107 to rotate. The screw 107 drives the moving block 108 to move. The moving block 108 drives the connecting plate 112 to move via the moving plate 109, the connecting rod 110, and the first electric telescopic rod 111, thereby driving the steel pipe into the water tank 1 for further cooling. This increases the cooling rate of the thick-walled steel pipe and reduces the impact on its mechanical properties.

[0030] Furthermore, such as Figure 1 As shown, a connecting block 4 is fixedly connected to the surface of the water tank body 1; a guide slide rod 401 is slidably connected inside the connecting rod 110; the two ends of the guide slide rod 401 are fixedly connected to the connecting block 4 and the water tank body 1 respectively; during operation, the connecting rod 110 slides on the guide slide rod 401 along with the moving plate 109, so that the guide slide rod 401 guides the connecting rod 110 horizontally, reducing the wear of the connecting rod 110 and making the movement of the connecting rod 110 stable.

[0031] Furthermore, such as Figure 1 As shown, a limiting bearing 5 is sleeved and connected to one end of the screw 107; the bottom of the limiting bearing 5 is fixedly connected to the water tank body 1; during operation, the screw 107 rotates on the water tank body 1 through the limiting bearing 5, which limits the screw 107, reduces the wear of the screw 107, and extends the service life of the screw 107.

[0032] Furthermore, such as Figure 1 As shown, the surface of the water tank body 1 is provided with a movable groove 6; the movable groove 6 is used in conjunction with the screw 107 and the moving block 108; during operation, the screw 107 and the moving block 108 move within the movable groove 6, so that the screw 107 and the moving block 108 have a uniform moving space, reducing the wear of the moving block 108 and the screw 107.

[0033] Working principle: A thick-walled seamless steel pipe is placed between two connecting plates 112. Then, the first electric telescopic rod 111 is activated, causing the connecting plates 112 to clamp the steel pipe, allowing the limiting post 113 to enter the pipe and limit its movement. Next, the rotating motor 114 and the high-pressure water spray head 116 are activated, causing the high-pressure water spray head 116 to spray water and cool the inside of the steel pipe. Simultaneously, the rotating motor 114 drives the rotating plate 115 to rotate, which in turn drives the high-pressure water spray head 116 to rotate and spray water evenly inside the steel pipe. Simultaneously, the drive motor 103 is activated, driving the drive wheel 104 to rotate. The drive wheel 104 drives the driven wheel 106 to rotate via the transmission belt 105.

This improves the cooling rate of the thick-walled steel pipe and reduces the impact on the mechanical properties of the steel pipe. After the steel pipe enters the water tank 1, the second electric telescopic rod 201 is activated. The second electric telescopic rod 201 drives the arc-shaped clamping plate 202 to fix and clamp the steel pipe, reducing the swaying of the steel pipe and keeping it stable. By activating the electric push rod 301, the electric push rod 301 drives the moving wheel 302 to move, making the moving wheel 302 contact the ground and lifting the water tank 1 off the ground, thus enabling the cooling device to be moved and its position changed. The connecting rod 110 slides on the guide slide rod 401 along with the moving plate 109, so that the guide slide rod 401 guides the connecting rod 110 horizontally, reducing the wear of the connecting rod 110 and making the movement of the connecting rod 110 stable. The screw 107 rotates on the water tank 1 through the limit bearing 5, limiting the movement of the screw 107, reducing the wear of the screw 107, and extending the service life of the screw 107. The screw 107 and the moving block 108 move and work in the movable groove 6, so that the screw 107 and the moving block 108 have a uniform working space, reducing the wear of the moving block 108 and the screw 107.
