Description

Technical Field

[0001] This utility model relates to the technical field of billet cooling, and in particular to an adjustable billet cooling nozzle structure. Background Technology

[0002] In the iron and steel metallurgical industry, the cooling process of cast billets is one of the key steps in the production process. During continuous casting, the high-temperature cast billets need to be rapidly cooled with cooling water to ensure the uniformity of their internal structure and surface quality. Traditional billet cooling systems typically employ a fixed nozzle structure, where cooling water is sprayed through the nozzles to form a water mist that cools the surface of the cast billet.

[0003] Traditional nozzles typically have a fixed water mist shape and spray range, making it impossible to flexibly adjust them according to the different sizes of the cast billet and cooling requirements. This results in uneven distribution of cooling water, with some areas being over- or under-cooled, affecting the quality of the cast billet. Utility Model Content

[0040] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0041] This utility model relates to an adjustable billet cooling nozzle structure, such as... Figures 1 to 6 As shown, it includes:

[0042] Installation mechanism 1 is independently fixed and used to support and fix the entire structure;

[0043] Connecting pipe 2 is rotatably mounted on mounting mechanism 1, and one end of connecting pipe 2 is supplied with an external water source;

The nozzle body 3 is set as a T-shaped structure, and nozzles 4 and assembly parts 5 are respectively installed at the two parallel mounting ports of the nozzle body 3. The nozzles 4 are used to spray cooling water mist.

[0045] The threaded rod 6 is installed inside the threaded hole of the assembly 5. An extension rod 7 is coaxially provided on the threaded rod 6, and an adjustment head 8 is provided on the extension rod 7. The adjustment head 8 is located at the water outlet of the nozzle 4. By adjusting the position of the threaded rod 6, the distance between the adjustment head 8 and the water outlet of the nozzle 4 can be changed, thereby adjusting the shape and spray range of the water mist.

[0046] The drive mechanism 9 is mounted on the mounting mechanism 1. The drive mechanism 9 is used to adjust the working height of the nozzle 4 to accommodate castings of different sizes.

[0047] The working principle of this device is as follows:

[0048] During use, cooling water enters the nozzle body 3 through the connecting pipe 2 and is sprayed out from the nozzle 4. By rotating the threaded rod 6, the position of the adjusting head 8 can be changed, thereby adjusting the shape and spray range of the water mist. At the same time, the drive mechanism 9 can adjust the height of the nozzle 4 according to the size of the billet to ensure that the cooling water can evenly cover the surface of the billet and achieve the best cooling effect.

[0049] The mounting mechanism 1 is independently fixed, providing stable support and fixation for the entire structure and ensuring operational stability. The connecting pipe 2 is rotatably mounted on the mounting mechanism 1, allowing for convenient and flexible direction adjustment. The nozzle body 3 has a T-shaped structure, with nozzles 4 and assembly parts 5 installed on both sides respectively. The reasonable layout allows the nozzles to efficiently spray cooling water mist. The threaded rod 6 is threadedly connected to the assembly part 5. By adjusting the position of the threaded rod 6, the distance between the adjusting head 8 and the outlet of the nozzle 4 can be precisely changed, thereby flexibly adjusting the shape and spray range of the water mist to meet the cooling needs of different billets. The drive mechanism 9 is mounted on the mounting mechanism and can conveniently adjust the working height of the nozzle 4 according to the billet size, ensuring that the cooling water evenly covers the surface of the billet, greatly improving the cooling effect, ensuring the quality of the billet, and improving production efficiency.

[0050] As a preferred option, such as Figures 1 to 6 As shown, the installation mechanism 1 includes:

[0051] Assembly plate 11, on which guide seat 12 is provided;

[0052] The movable part 13 is disposed on the guide seat 12 and is slidably installed along the length direction of the guide seat 12;

[0053] The transmission mechanism 14 is mounted on the assembly plate 11 and is connected to the drive mechanism 9 and the moving part 13 respectively.

[0054] Mounting component 15 is mounted on movable component 13, and mounting component 15 is provided with support component 16. Adaptor pipe 17 is rotatably mounted on support component 16, and connecting pipe 2 is coaxially fixedly mounted on adapter pipe 17.

[0055] Adjustment mechanism 18 is mounted on mounting part 15 and is installed in conjunction with adapter pipe 17. Adjustment mechanism 18 is used to connect pipe 2 to drive nozzle 4 to swing, so as to change the cooling range.

[0056] The mounting mechanism 1 cooperates with the moving part 13 via the guide seat 12 on the assembly plate 11, allowing the moving part 13 to slide along the length of the guide seat 12. The transmission mechanism 14 connects the drive mechanism 9 and the moving part 13, and can precisely drive the moving part 13 to move according to the instructions of the drive mechanism 9, thereby adjusting the horizontal position of the nozzle 4 to meet the cooling requirements of different sized billets. The mounting part 15 is set on the moving part 13, and its support part 16 is rotatably set with the adapter pipe 17 and coaxially fixed with the connecting pipe 2, which facilitates the rotation of the connecting pipe 2. The adjustment mechanism 18 cooperates with the adapter pipe 17, allowing the connecting pipe 2 to drive the nozzle 4 to swing, flexibly changing the cooling zone, covering the surface of the billet in all directions, and improving the cooling uniformity.

[0057] As a preferred option, such as Figures 1 to 5 As shown, the adjustment mechanism 18 includes:

[0058] Cylinder 18a is mounted on mounting part 15, and the direction of the power output end of cylinder 18a is perpendicular to the rotation axis of connecting pipe 2.

[0059] A rack 18b is installed at the output end of cylinder 18a, and the rack 18b is slidably connected to the mounting part 15;

[0060] The transmission gear 18c is coaxially mounted on the adapter tube 17, and the spur rack 18b is meshed with the transmission gear 18c.

[0061] Cylinder 18a is mounted on mounting part 15, and its power output end is perpendicular to the rotation axis of connecting pipe 2, which can accurately provide driving force. Spur rack 18b is mounted on the output end of cylinder 18a and is slidably connected to mounting part 15, which can stably transmit the linear motion of cylinder 18a. Transmission gear 18c is coaxially mounted on adapter pipe 17 and meshes with spur rack 18b. When cylinder 18a works to push spur rack 18b to move, it drives transmission gear 18c to rotate through meshing transmission, thereby making adapter pipe 17 and connecting pipe 2 rotate synchronously, realizing the precise swing of nozzle 4 and flexibly and efficiently changing the cooling range.

[0062] As a preferred option, such as Figures 1 to 6 As shown, the transmission mechanism 14 includes:

[0063] The fastener 14a is installed on the assembly plate 11, and the fastener 14a has an inner hole.

[0064] The threaded post 14b is rotatably installed in the inner hole of the fixed part 14a, and the threaded post 14b is fitted with the threaded hole of the movable part 13.

[0065] A hollow shaft 14c is rotatably mounted on an assembly plate 11, and a worm gear 14d is coaxially mounted on the hollow shaft 14c.

[0066] Worm gear 14e is coaxially mounted on threaded post 14b, and worm 14d is meshed with worm gear 14e.

[0067] The fixing component 14a is mounted on the assembly plate 11. Its inner hole provides stable rotational support for the threaded column 14b. The threaded column 14b engages with the threaded hole of the moving component 13, which can convert the rotation into linear movement of the moving component 13 along the guide seat 12. The hollow shaft 14c is rotatably mounted on the assembly plate 11. The worm gear 14d and worm wheel 14e are coaxially mounted on it and mesh with each other. The worm wheel 14e is coaxially mounted on the threaded column 14b. This worm gear transmission structure has a large transmission ratio and can achieve precise speed adjustment. When the drive mechanism 9 operates and drives the hollow shaft 14c to rotate, the worm gear 14d drives the worm wheel 14e, thereby precisely controlling the rotation of the threaded column 14b. Finally, the moving component 13 is moved smoothly and accurately, ensuring that the horizontal position of the nozzle 4 can be finely adjusted according to different billet sizes.

[0068] As a preferred option, such as Figures 1 to 2 As shown, the drive mechanism 9 includes:

[0069] The drive shaft 91 is installed in the inner cavity of the hollow shaft 14c, and the hollow shaft 14c rotates synchronously with the drive shaft 91.

[0070] Servo motor 92 is mounted at one end of drive shaft 91 and is used to provide rotational power to drive shaft 91;

[0071] The drive shaft 91 is installed inside the hollow shaft 14c, allowing the hollow shaft 14c to rotate synchronously with the drive shaft 91, thus establishing an efficient and stable power transmission path. The servo motor 92 is installed at one end of the drive shaft 91. With its precise speed control and fast response characteristics, it can provide stable and precise rotational power to the drive shaft 91. When it is necessary to adjust the horizontal position of the nozzle 4 according to the billet size, the servo motor 92 precisely outputs power, driving the drive shaft 91 to rotate, which in turn drives the hollow shaft 14c to rotate. Through the meshing transmission of the worm gear 14d and the worm wheel 14e, the power is precisely transmitted to the threaded column 14b, realizing the smooth and precise displacement of the moving part 13.

[0072] As a preferred option, such as Figures 1 to 2 As shown, at least one mounting mechanism 1 is provided, and the connecting pipe 2 corresponds one-to-one with the mounting mechanism 1. The drive shaft 91 is connected to multiple coaxially mounted hollow shafts 14c for simultaneous synchronous height adjustment of multiple nozzles 4.

[0073] This design allows for flexible layout of multiple cooling points according to the actual needs of the billet, fully covering the billet surface and improving the cooling effect. The drive shaft 91 is connected to multiple coaxially mounted hollow shafts 14c, which enables synchronous adjustment of the height of multiple nozzles 4. This design greatly improves the adjustment efficiency, avoids the tedious operation of adjusting one by one, and ensures that each nozzle 4 can be accurately adapted to different billet sizes at the same time.

[0074] As a preferred option, such as Figures 1 to 6 As shown, the assembly plate 11 is provided with multiple connection holes for fixing and installing the assembly plate 11.

[0075] The multiple connection holes provided on the assembly plate 11 greatly facilitate its fixed installation. These connection holes can accommodate a variety of different specifications and types of installation accessories, such as bolts, nuts, or other fastening components, and can easily be matched to meet diverse installation needs. Fixing through multiple connection holes can significantly enhance the stability of the assembly plate 11 installation, evenly distribute the force borne during installation, effectively prevent loosening or displacement caused by uneven force at a single point, and ensure that the entire installation mechanism 1 is stable and reliable.

[0076] As a preferred option, such as Figures 1 to 3 As shown, an adjusting handle 10 is coaxially mounted on the threaded rod 6;

[0077] The adjustment handle 10, which is coaxially mounted on the threaded rod 6, greatly improves the ease of operation. In actual operation, the operator can easily rotate the threaded rod 6 by directly holding the adjustment handle 10 without the need for additional complicated tools.

[0078] The adjustable billet cooling nozzle structure of this utility model can be installed, connected or set in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0079] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
