[0039] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0040] Reference Figures 1-7 For the first embodiment of the utility model, a spray head for hot rolling and cooling of bar is proposed, which is used for cooling metal bar, comprising a spray seat 1, the spray seat 1 has a first cavity 101, the spray seat 1 also has a water inlet 102 and a plurality of first spray openings 103, the water inlet 102 and the first spray opening 103 are communicated with the first cavity 101; the rotating disc 2 is rotatably arranged on the spray seat 1, the rotating disc 2 coincides with the axis of the spray seat 1, the rotating disc 2 has a second cavity 201, the rotating disc 2 also has a plurality of second spray openings 202, the second spray opening 202 is communicated with the second cavity 201, the first cavity 101 and the second cavity 201 are communicated or disconnected after the rotating disc 2 rotates.

[0041] In this embodiment, in order to solve the problem that the spray head for hot rolling and cooling of bar in the related art cannot quickly adjust the water spraying amount, a spray head for hot rolling and cooling of bar is designed. When the rotating disc 2 rotates to a specific position, the first cavity 101 and the second cavity 201 are communicated, water can flow into the first cavity 101 from the water inlet 102, then enter the second cavity 201, and finally be sprayed out from the second spray opening 202; when the rotating disc 2 rotates to another position, the two are disconnected, water can only be sprayed out from the first spray opening 103 or stop spraying.

[0042] The advantage is that by rotating the rotating disc 2 to control the communication state of the first cavity 101 and the second cavity 201, the water spraying path and the water spraying amount of the spray head can be simply and effectively changed, providing a quick adjustment method compared to the traditional spray head that cannot be adjusted, which can adapt to different cooling needs.

[0043] Further, it also includes a sliding plate 3, which is slidingly arranged relative to the rotating disc 2, and a spraying space is formed between the sliding plate 3 and the rotating disc 2, which is in communication with the second cavity 201, and the spraying space is opened or closed after the sliding plate 3 slides.

[0044] In this embodiment, by controlling the sliding of the sliding plate 3, the spraying space can be opened or closed. When the sliding plate 3 slides to a certain position, the spraying space is opened, and water can flow from the second cavity 201 into the spraying space and be sprayed out; when the sliding plate 3 slides to other positions, the spraying space is closed, and water cannot be sprayed out of this path.

[0045] The advantage is that the setting of the sliding plate 3 further increases the adjustment method of the water spraying amount. On the basis of the adjustment of the rotating disc 2, the opening and closing of the spraying space can be more finely controlled through the sliding of the sliding plate 3, so as to more accurately adjust the water spraying amount, better adapt to different steel composition, rolling temperature and environmental conditions, further improve the uniformity of cooling, and reduce the defects such as insufficient strength, reduced toughness and cracking of steel bars caused by uneven cooling.

[0046] Further, it also includes a mounting frame 4, which has a plurality of mounting portions 401, and the spray seat 1 is arranged on the mounting portion 401, and the first spray port 103, the second spray port 202 and the spraying space are all directed towards the metal bar.

[0047] In this embodiment, the spray seat 1 is firmly fixed on the mounting frame 4, and the angle of the spray seat 1 is adjusted so that each spray port and the spraying space can accurately spray water to the surface of the metal bar that needs to be cooled.

[0048] The advantage is that the existence of the mounting frame 4 makes the overall structure of the spray head more stable, which is convenient for installation and layout on the hot rolling production line. By reasonably arranging the mounting portion 401, it can be ensured that the spray seat 1 and the spray ports and the spraying space thereon are accurately aligned with the metal bar, improving the efficiency and accuracy of cooling, making the cooling process more stable and reliable, and being conducive to ensuring the quality of the steel bar.

[0049] Further, the spray seat 1 has a plurality of clamping grooves 104, which are divided into sliding segments 1041 and clamping segments 1042, and further includes a plurality of clamping rods 5, which are arranged on the mounting portion 401; the clamping groove 104 is configured such that the clamping rod 5 is used to pass through the sliding segment 1041 into the clamping segment 1042 to limit the relative position of the spray seat 1 and the mounting portion 401.

[0050] In this embodiment, when installing the spray seat 1, the spray seat 1 is close to the mounting part 401, the clamping rod 5 first slides along the sliding section 1041, and then enters the clamping section 1042. At this time, the clamping rod 5 limits the relative position of the spray seat 1 and the mounting part 401, so that the spray seat 1 is fixed on the mounting part 401. When it is necessary to disassemble the spray seat 1, the spray seat 1 is again close to the mounting part 401, and the clamping rod 5 slides out of the clamping section 1042 and the sliding section 1041, thereby releasing the position limitation of the spray seat 1 and the mounting part 401, so that the spray seat 1 can be removed.

[0051] The advantage is that this clamping structure makes the installation and disassembly between the spray seat 1 and the mounting frame 4 convenient and fast. When it is necessary to maintain, replace the spray seat 1 or adjust the layout of the spray head, the operation can be quickly performed, the maintenance efficiency of the production equipment is improved, the production stagnation time caused by equipment maintenance is reduced, and the production efficiency of the whole hot rolling production line is improved.

[0052] Further, it further includes an elastic member 6, and the two ends of the elastic member 6 act on the mounting part 401 and the spray seat 1 respectively, and is used to provide a force for moving the spray seat 1 away from the mounting part 401.

[0053] In this embodiment, a suitable spring can be selected as the elastic member 6, one end of the elastic member 6 is fixed on the mounting part 401, and the other end is fixed on the corresponding position of the spray seat 1. In the normal installation state, the elastic member 6 is in a compressed state, and when it is necessary to disassemble the spray seat 1, the elastic force of the spring helps to push the spray seat 1 to move, so that the clamping rod 5 is more easily slid into or slid out of the clamping groove 104.

[0054] The advantage is that the setting of the elastic member 6 further assists the disassembly process of the spray seat 1. The elastic force provided by the elastic member 6 can automatically push the spray seat 1 during disassembly, reduces the external force required for manual disassembly, makes the disassembly operation more easy and convenient, improves the convenience and efficiency of equipment maintenance, and also reduces the risk of damaging the equipment due to improper disassembly.

[0055] Further, it further includes a rotating shaft 7, one end of the rotating shaft 7 penetrates the spray seat 1 and is connected with the rotating disc 2, and the other end penetrates the mounting part 401, and the rotating shaft 7 rotates to drive the rotating disc 2 to rotate.

[0056] In this embodiment, the rotating shaft 7 is installed, one end of the rotating shaft 7 penetrates the spray seat 1 and is connected with the rotating disc 2, and the other end penetrates the mounting part 401. By rotating the rotating shaft 7, the rotating disc 2 can be driven to rotate around the axis of the spray seat 1. Bearings can be arranged at the connection between the rotating shaft 7 and the spray seat 1 and the mounting part 401 to reduce the friction during rotation, so that the rotation is more smooth.

[0057] The advantage is that the rotation of the rotating shaft 7 provides a stable and reliable transmission mode for the rotation of the rotating disc 2. By rotating the rotating shaft 7 to control the rotation of the rotating disc 2, it is more simple and direct, easy to operate and control, and can accurately realize the switching of the rotating disc 2 at different positions, thereby effectively adjusting the water spraying amount and ensuring the uniformity and stability of the cooling effect.

[0058] Further, it also includes a gear 8, which is arranged at the end of the rotating shaft 7 away from the rotating disc 2, and the gear 8 drives the rotating shaft 7 to rotate after rotating; the driving member 9 is arranged on the mounting frame 4, and the driving end of the driving member 9 is engaged with the gear 8 to drive the gear 8 to rotate.

[0059] In this embodiment, the gear 8 is arranged at the end of the rotating shaft 7 away from the rotating disc 2, and the driving member 9 is installed on the mounting frame 4, and the driving end of the driving member 9 is engaged with the gear 8. When the driving member 9 works, the driving member 9 drives the gear 8 to rotate, and the rotation of the gear 8 drives the rotating shaft 7 to rotate, and further drives the rotating disc 2 to rotate. The driving member 9 can select a motor or other power equipment, and by controlling the forward and reverse rotation and speed of the motor, the rotation angle and speed of the gear 8 can be accurately controlled, thereby realizing accurate control of the rotation of the rotating disc 2.

[0060] The advantage is that through the combination of the driving member 9 and the gear 8, the automatic control of the rotation of the rotating disc 2 is realized. Compared with manually rotating the rotating shaft 7, this automatic control method is more accurate and efficient, and can adjust the rotation of the rotating disc 2 according to the preset program or real-time monitoring data, better adapt to different production process requirements, improve the intelligent degree and production efficiency of the cooling process, and also reduce the errors and uncertainties caused by manual operation.

[0061] Further, the rotating shaft 7 has a through slot 701, and further includes a telescopic member 10, which is arranged on the mounting frame 4, and the extension end of the telescopic member 10 is connected with the sliding plate 3 through the through slot 701, and after the telescopic member 10 is extended, the sliding plate 3 is close to the rotating disc 2.

[0062] In this embodiment, the through slot 701 is machined on the rotating shaft 7, and then the telescopic member 10 is installed on the mounting frame 4, and the extension end of the telescopic member 10 is connected with the sliding plate 3 through the through slot 701. When the telescopic member 10 is extended, the telescopic member 10 pushes the sliding plate 3 to be close to the rotating disc 2, thereby controlling the opening and closing of the spraying space. The telescopic member 10 can select an electric telescopic rod or a hydraulic telescopic rod, and by controlling the extension length of the telescopic member 10, the position of the sliding plate 3 can be accurately controlled, and the water spraying amount can be accurately adjusted.

[0063] The advantage is that the telescopic member 10 realizes the automatic control of the sliding of the sliding plate 3. Compared with manually sliding the sliding plate 3, the automatic control can more accurately adjust the size of the spraying space, thereby more accurately controlling the water spraying amount.
