[0034] like Figure 1 As shown, a quenching spray equipment in one embodiment of the present invention includes a conveying mechanism 1, an induction heating furnace 2 and a cooling device 3. The induction heating furnace 2 is arranged on the conveying mechanism 1, and is used to quench the profile; the cooling device 3 is arranged on the conveying mechanism 1, and the conveying mechanism 1 passes through the induction heating furnace 2 and the cooling device 3 in sequence. The profile is conveyed to the induction heating furnace 2 and the cooling device 3 on the conveying mechanism 1. The cooling device 3 includes a cooling box 31, a first cooling mechanism 32 and a second cooling mechanism 33. The first cooling mechanism 32 is arranged on the two side walls of the cooling box 31 and is fixedly connected to the cooling box 31, and the second cooling mechanism 33 is arranged on the top of the cooling box 31 and is fixedly connected to the cooling box 31. By setting up a cooling box 31, a closed cooling environment is provided for the profile, which helps to reduce the impact of the external environment on the cooling process and ensure the uniformity and stability of cooling; by setting up a first cooling mechanism 32, by spraying coolant, it can directly act on the surface of the profile in all directions to achieve rapid and uniform cooling; by setting up a second cooling mechanism 33, by exhausting air, the flow of air inside the cooling box 31 can be accelerated, thereby reducing the temperature inside the cooling box 31, helping to maintain the low temperature state of the profile during the quenching process and improving the cooling efficiency. On the basis of spraying coolant, the second cooling mechanism 33 provides an additional cooling method. By adjusting parameters such as air volume, wind speed and wind direction, the cooling effect can be further optimized to ensure the cooling uniformity and quality of the profile.

[0035] See also Figure 2As a preferred embodiment of the present invention, it may also have the following additional technical features: the first cooling mechanism 32 includes a water tank 321, a spray assembly 322 and a water pump 323. The water tank 321 is fixedly connected to the outer wall of the cooling box 31 to ensure that there is enough coolant available and to allow the coolant to maintain a certain pressure and temperature during the circulation process. The spray assembly 322 is connected and communicated with the water tank 321 and is responsible for transporting the coolant from the water tank 321 to the profile in the cooling box 31 to achieve the purpose of spray cooling the profile. The water pump 323 is arranged on the spray assembly 322 and is fixedly connected to the spray assembly 322. By using the water pump 323 and the spray assembly 322, it can be ensured that the coolant is evenly sprayed on the profile at a certain pressure and flow rate.

[0036] See also Figure 3 As a preferred embodiment of the present invention, it may also have the following additional technical features: the spray assembly 322 includes a water pumping pipe 3221, a water inlet pipe 3222, a spray pipe 3223 and a spray nozzle 3224, one end of the water pumping pipe 3221 is fixedly connected to the water storage tank 321, the end of the water pumping pipe 3221 away from the water storage tank 321 passes through the cooling box 31 and is fixedly connected to the water inlet pipe 3222, the water inlet pipe 3222 is fixedly connected to the inner wall of the cooling box 31, and a plurality of equidistant and uniformly spaced water inlet pipes 3222 are provided along the length direction thereof. The spray pipes 3223 arranged at intervals realize uniform spraying of the coolant, which helps to ensure that all parts of the object to be cooled can be fully cooled. Each spray pipe 3223 is connected to the water inlet pipe 3222, and one end of each spray pipe 3223 away from the water inlet pipe 3222 is fixedly connected to the spray nozzle 3224. The spray nozzle 3224 is arranged in a truncated cone shape, and the radius of the spray nozzle 3224 close to the end of the water inlet pipe 3222 gradually expands toward the radius away from the end of the water inlet pipe 3222, so as to form a fan-shaped spray surface and increase the coverage of the coolant. Of course, the number and spacing of the spray pipes 3223 can be adjusted according to actual conditions to optimize the spraying effect.

[0037] See also Figure 4As a preferred embodiment of the present invention, it may also have the following additional technical features: the spray pipe 3223 includes a first pipe 32231 and a second pipe 32232, the first pipe 32231 is connected to the second pipe 32232, the first pipe 32231 is used to pass coolant, and the second pipe 32232 is used to communicate with an external air source. In this embodiment, the second pipe 32232 can be directly connected to the air pump. The first pipe 32231 is provided with a first spray sleeve 32233 and a second spray sleeve 32234. The first spray sleeve 32233 is arranged on a side away from the spray nozzle 3224, and the second spray sleeve 32234 is arranged on a side close to the spray nozzle 3224. The second pipe 32232 is arranged between the first spray sleeve 32233 and the second spray sleeve 32234. The airflow entering the second pipe 32232 is mixed with the coolant sprayed from the first spray pipe 3223 and flows to the second spray sleeve 32234. The water outlet of the second spray sleeve 32234 is sprayed in the form of water vapor by the spray nozzle 3224. By introducing the airflow to mix with the coolant, the surface area and heat dissipation capacity of the cooling medium are increased. The airflow can also take away part of the heat, accelerate the cooling process, and can cool the object to be cooled more efficiently. At the same time, the mixing of the coolant and the airflow in the spray sleeve ensures that the cooling medium has a more uniform distribution when spraying, and can reduce the amount of coolant to a certain extent.

[0038] As a preferred embodiment of the present invention, it may also have the following additional technical features: a pressurizing section 32235 and a liquid spraying section 32236 are added to the first spray sleeve 32233, the pressurizing section 32235 is connected and communicated with the liquid spraying section 32236, the pressurizing section 32235 is arranged in a truncated cone shape, and the radius of the pressurizing section 32235 is gradually expanded in the direction away from the spray nozzle 3224, thereby increasing the pressure of the coolant when passing through, so that the coolant is sprayed out at a higher speed in the liquid spraying section 32236, which is conducive to the diffusion of water mist or water vapor and covers a wider area. The area is increased to improve the spraying efficiency. The spray section 32236 is arranged in a cylindrical shape. The cross section of the spray section 32236 is equal to the cross section of the pressurizing section 32235 at one end close to the spray nozzle 3224, so that the coolant can maintain a constant flow rate and pressure in the spray section 32236, avoiding the flow instability caused by the change of cross-sectional area. The second pipe 32232 is arranged between the spray section 32236 and the second spray sleeve 32234, ensuring that the airflow is mixed with the pressurized and stabilized coolant before entering the second spray sleeve 32234.

[0039] As a preferred embodiment of the present invention, it may also have the following additional technical features: a mixing section 32237, a transition section 32238 and a diverging section 32239 are additionally provided in the second spray sleeve 32234; the mixing section 32237, the transition section 32238 and the diverging section 32239 are connected and communicated in sequence; the mixing section 32237 is arranged in a truncated cone shape; the radius of the mixing section 32237 is gradually expanded in the direction away from the spray nozzle 3224, so that the coolant and the airflow can fully contact and mix in the mixing section 32237, thereby increasing the uniformity and efficiency of the mixing; the open end of the diverging section 32239 is arranged toward the spray nozzle 3224; the diverging section 32239 is communicated with the spray nozzle 3224, thereby further increasing the spray area and uniformity of the mixed liquid; the second pipe 32232 is arranged between the first spray pipe 3223 and the mixing section 32237. The full mixing of the coolant and the airflow increases the heat dissipation area and heat dissipation efficiency of the mixed liquid. At the same time, the spraying method of the divergent section 32239 also helps to distribute the mixed liquid more evenly on the surface of the object to be cooled, thereby improving the cooling effect.

Finally, each fan blade 3332 is driven by the transmission cover 3335 to synchronize the angle reset rotation relative to the fixed hole 33313 to ensure that more air is sent to the cooling box 31, so as to ensure the temperature in the cooling box 31. The second cooling mechanism 33 can be adjusted according to different quenching requirements. For example, by changing the speed of the driving motor 331 and the angle of the fan blade 3332, it can meet the quenching requirements of profiles with different diameters and lengths.

[0045] The working principle of the quenching spray equipment of this embodiment is as follows: First, the profile is placed on the conveying mechanism 1, and as the conveying mechanism 1 operates, it is conveyed to the induction heating furnace 2 and the cooling device 3 in turn. In the induction heating furnace 2, the steel pipe is subjected to the high-frequency induced current and is rapidly heated to the quenching temperature. The heated steel pipe enters the cooling device 3, and is first subjected to the spray coolant of the first cooling mechanism 32 to achieve rapid cooling; then, the second cooling mechanism 33 further reduces the temperature in the cooling box 31 by means of air outlet, thereby accelerating the cooling process. The cooperation of the spray assembly 322 and the cold air mechanism 333 ensures that the cooling medium can evenly cover the surface of the steel pipe, avoiding the problem of poor organizational structure caused by uneven cooling.

[0046] The quenching spray equipment of this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other equipment with similar usage requirements. In this embodiment, the quenching spray equipment effectively ensures uniform cooling of the material through the cooperation of the first cooling mechanism 32 and the second cooling mechanism 33, thereby ensuring the dimensional accuracy and shape accuracy of the material.
