Description

Technical Field

[0001] This utility model relates to the field of bulb flat steel processing technology, and in particular to a multi-layer controlled cooling device for large bulb flat steel. Background Technology

[0002] Bulb flat steel is a medium-sized steel profile mainly used in shipbuilding and bridge construction. Among them, marine bulb flat steel is an auxiliary medium-sized steel profile used in shipbuilding. After the bulb flat steel is rolled, it needs to be cooled down using a cooling device.

[0003] In existing technologies, after large bulb flat steel is rolled, the temperature is relatively high, and its internal structure is in an unstable state. When the surface of the bulb flat steel is cooled by water alone, the surface temperature of the bulb flat steel will drop rapidly, resulting in a large temperature difference between the surface and the interior. This causes the bulb flat steel to generate large thermal stress, which can easily lead to deformation and cracking, thereby affecting the production quality of the bulb flat steel. Utility Model Content

[0004] This utility model mainly provides a multi-layer controlled cooling device for large spherical flat steel that reduces deformation and improves cooling effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer controlled cooling device for large spherical flat steel, comprising a conveying assembly, an adjusting mechanism installed on the other side of the conveying assembly, a cooling mechanism disposed on the outer side of the adjusting mechanism, the cooling mechanism comprising a first fixed box, one side of the first fixed box being fixedly connected to one side of the conveying assembly, a protective cover being fixedly connected to the side of the first fixed box, a cooling fan being installed on the inner side of the protective cover, a second fixed box being installed on one side of the first fixed box, one side of the second fixed box being fixedly connected to one side of the conveying assembly, a mounting frame being fixedly connected to the side of the second fixed box, a mounting plate being fixedly connected inside the mounting frame, a connecting collar being fixedly connected to the middle of the mounting plate, and a connecting collar being fixedly connected to the outer surface of the connecting collar. A water outlet pipe is connected to a nozzle at one end, allowing the flat steel ball to be moved into the first fixed box. Protective covers and cooling fans are installed on the top and sides of the first fixed box. The cooling fans first cool the surface of the flat steel ball, initially lowering its temperature and reducing the temperature difference between the surface and interior. Then, the flat steel ball is moved into the second fixed box, where cooling water is delivered through a first connecting pipe, a second connecting pipe, a connecting collar, and the water outlet pipe to the nozzles. The water is sprayed from multiple nozzles arranged in a ring, with varying spray angles to uniformly cool the surface. The combination of air and water cooling ensures a smoother temperature change during cooling, effectively controlling thermal stress and reducing deformation, thus better guaranteeing the dimensional accuracy of the flat steel ball.

[0006] Preferably, the other end of the connecting collar is fixedly connected to the second connecting pipe, and one end of the second connecting pipe is fixedly connected to the first connecting pipe. A cooling water conveying device is connected to the first connecting pipe to deliver cooling water to the interior of the three second connecting pipes respectively.

[0007] Preferably, a guide frame is provided on one side of the second fixed box, and one side of the guide frame is fixedly connected to one side of the conveying component. The water sprayed from the nozzle is guided and collected by the guide frame.

[0008] Preferably, the adjusting mechanism includes an adjusting plate, both ends of which are fixedly connected to connecting plates. One end of the connecting plate is fixedly connected to a moving block. A threaded rod is threadedly connected to the middle of a set of moving blocks. Both ends of the threaded rod are rotatably connected to a first fixed block. One end of the first fixed block is fixedly connected to one side of the conveying assembly. A reduction motor is fixedly connected to one side of the conveying assembly. The output end of the reduction motor is fixedly connected to one end of the threaded rod. The reduction motor drives the threaded rod to rotate. The threads on both sides of the threaded rod are arranged in opposite directions, causing the two threaded moving blocks to move, which in turn moves the connecting plate and the adjusting plate. This movement of the adjusting plate keeps the ball flat steel in a centered position, facilitating uniform cooling of the ball flat steel surface and improving the cooling effect.

[0009] Preferably, a guide rod is slidably connected to the middle of another set of moving blocks, and a second fixing block is fixedly connected to the end of the guide rod. One end of the second fixing block is fixedly connected to one side of the conveying assembly. During the movement of the adjusting plate, the moving block slides outside the guide rod, which facilitates the linear movement of the fixed adjusting plate.

[0010] Preferably, a drive assembly is installed on one side of the conveying assembly. The drive assembly consists of a drive motor and a chain and sprocket assembly, and is used to drive multiple conveying rollers on the conveying assembly to convey the bulb flat steel.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the surface of the bulb flat steel is cooled by air through the operation of a cooling fan, reducing the temperature difference between the surface and the interior. Then, cooling water is transported to the nozzles through the first connecting pipe, the second connecting pipe, the connecting collar, and the water outlet pipe. The water is sprayed out from multiple nozzles arranged in a ring, cooling the surface of the bulb flat steel with water. The combination of air cooling and water cooling makes the temperature change of the bulb flat steel more gradual during the cooling process, effectively controlling thermal stress, reducing thermal stress and deformation, and thus better ensuring the dimensional accuracy of the bulb flat steel.

[0013] 2. In this utility model, the screw rod is driven to rotate by the working of the geared motor, which causes the two moving blocks to move, thereby moving the connecting plate and the adjusting plate. The movement of the two adjusting plates keeps the bulb flat steel in the center position, which facilitates uniform cooling of the bulb flat steel surface and improves the cooling effect.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figure 1 - Figure 4This utility model provides a technical solution: a multi-layer controlled cooling device for large spherical flat steel, including a conveying assembly 1, an adjusting mechanism 3 installed on the other side of the conveying assembly 1, a cooling mechanism 4 arranged on the outside of the adjusting mechanism 3, the cooling mechanism 4 including a first fixed box 41, one side of the first fixed box 41 fixedly connected to one side of the conveying assembly 1, a protective cover 42 fixedly connected to the side of the first fixed box 41, a cooling fan 43 installed inside the protective cover 42, a second fixed box 45 installed on one side of the first fixed box 41, one side of the second fixed box 45 fixedly connected to one side of the conveying assembly 1, a mounting frame 48 fixedly connected to the side of the second fixed box 45, a mounting plate 49 fixedly connected inside the mounting frame 48, a connecting collar 410 fixedly connected to the middle of the mounting plate 49, and a water outlet pipe 47 fixedly connected to the outer surface of the connecting collar 410. The bulb flat steel is moved into the first fixed box 41 by the fixed nozzle 411. The top and sides of the first fixed box 41 are equipped with protective covers 42 and cooling fans 43. First, the cooling fans 43 work to air cool the surface of the bulb flat steel, so that the surface temperature of the bulb flat steel is initially reduced and the temperature difference between the surface and the interior is reduced. Then the bulb flat steel is sent into the second fixed box 45. Cooling water is transported to the nozzle 411 through the first connecting pipe 44, the second connecting pipe 412, the connecting collar 410 and the water outlet pipe 47. It is sprayed from multiple nozzles 411 arranged in a ring. At the same time, the spray angle of the nozzles 411 is different, which can uniformly cool the surface of the bulb flat steel. The combination of air cooling and water cooling makes the temperature change of the bulb flat steel more gradual during the cooling process, and the thermal stress is effectively controlled, reducing thermal stress and deformation, thereby better ensuring the dimensional accuracy of the bulb flat steel.

[0022] like Figure 3 As shown, the other end of the connecting collar 410 is fixedly connected to the second connecting pipe 412, and one end of the second connecting pipe 412 is fixedly connected to the first connecting pipe 44. The cooling water is delivered to the interior of the three second connecting pipes 412 through the cooling water delivery device connected to the first connecting pipe 44.

[0023] like Figure 2 As shown, a guide frame 46 is provided on one side of the second fixed box 45. One side of the guide frame 46 is fixedly connected to one side of the conveying assembly 1. The water sprayed from the nozzle 411 is guided and collected by the guide frame 46.

[0024] like Figure 4As shown, the adjusting mechanism 3 includes an adjusting plate 36, with connecting plates 34 fixedly connected to both ends of the adjusting plate 36. A moving block 33 is fixedly connected to one end of the connecting plate 34. A threaded rod 32 is threadedly connected to the middle of a set of moving blocks 33. Both ends of the threaded rod 32 are rotatably connected to a first fixed block 35. One end of the first fixed block 35 is fixedly connected to one side of the conveying assembly 1. A reduction motor 31 is fixedly connected to one side of the conveying assembly 1. The output end of the reduction motor 31 is fixedly connected to one end of the threaded rod 32. The reduction motor 31 drives the threaded rod 32 to rotate. The threads on both sides of the threaded rod 32 are arranged in opposite directions, causing the two threaded moving blocks 33 to move, which in turn drives the connecting plate 34 and the adjusting plate 36 to move. This movement of the adjusting plate 36 keeps the flat steel ball in the center position, facilitating uniform cooling of the flat steel ball surface and improving the cooling effect.

[0025] like Figure 4 As shown, the middle of another set of moving blocks 33 is slidably connected to the guide rod 37, and the end of the guide rod 37 is fixedly connected to the second fixing block 38. One end of the second fixing block 38 is fixedly connected to one side of the conveying assembly 1. During the movement of the adjusting plate 36, the moving block 33 slides outside the guide rod 37, which facilitates the linear movement of the fixed adjusting plate 36.

[0026] like Figure 2 As shown, a drive assembly 2 is installed on one side of the conveying assembly 1. The drive assembly 2 consists of a drive motor and a chain and sprocket assembly, and is used to drive multiple conveying rollers on the conveying assembly 1 to convey the bulb flat steel.

[0027] The operating method and working principle of this device are as follows: The drive assembly 2 drives the conveying assembly 1 to move the ball flat steel. The reduction motor 31 drives the threaded rod 32 to rotate, causing the two moving blocks 33 to move, which in turn drives the connecting plate 34 and the adjusting plate 36 to move. The adjusting plate 36 moves to keep the ball flat steel in the center position and moves the ball flat steel into the first fixed box 41. The cooling fan 43 works to air cool the surface of the ball flat steel. Then the ball flat steel is sent into the second fixed box 45. The first connecting pipe 44 is connected to a cooling water conveying device, which delivers cooling water through the second connecting pipe 412, the connecting collar 410 and the water outlet pipe 47 to the nozzles 411. The water is sprayed from multiple nozzles 411 to water cool the surface of the ball flat steel. The combination of air cooling and water cooling effectively cools the ball flat steel.
