Figure 10In this embodiment, a through hole 33314 is further provided on the positioning cover 3331, each through hole 33314 is arranged on the second matching groove 33312 and is connected to the corresponding fixing hole 33313, the rotating assembly 3334 also includes a braking structure 33344, the braking structure 33344 includes a connecting plate 33344a, a support frame 33344b and a brake block 33344c, the connecting plate 33344a is arranged in a Z shape, the middle part of the connecting plate 33344a is rotatably connected to the corresponding support frame 33344b through a torsion spring, and one end of the connecting plate 33344a passes through the through hole 33314 to the second matching groove In 33312, the other end of the connecting plate 33344a is fixedly connected to the brake block 33344c, and one end of the connecting plate 33344a passes through the through hole 33314 to the second matching groove 33312 and is located on the side of the through hole 33314 close to the first matching groove 33311, and when the telescopic structure 33342 is fully retracted, the distance between it and the sliding block 33342b is 3-5mm, and a brake groove 33332 is provided at one end of the rotating shaft 3333. Under the reset action of the above-mentioned torsion spring, the brake block 33344c is tightly fitted with the brake groove 33332, thereby realizing rotational braking of the rotating shaft 3333.

[0043] As a preferred embodiment of the present invention, it may also have the following additional technical features: the telescopic structure 33342 includes a telescopic rod 33342a and a sliding block 33342b, the telescopic rod 33342a being fixedly mounted in the second mating groove 33312, the sliding block 33342b being fixedly connected to the telescopic end of the telescopic rod 33342a, and the connecting rod 33343 being rotatably connected to the telescopic end of the telescopic rod 33342a. In this embodiment, the output end of the telescopic rod 33342a is connected to the housing of the telescopic rod 33342a via a tension return spring. When the telescopic rod 33342a is extended by an external force, the spring provides a reverse pulling force, causing the telescopic rod 33342a to quickly return to its naturally retracted state after the external force disappears. When the telescopic rod 33342a is in the naturally retracted state, the angle between the tangent plane at the corresponding connection point between the connecting plane and the edge of the rotating disk 33341 is acute.

[0044] During operation, when the second cooling mechanism 33 is started, the driving motor 331 drives the rotating drive shaft 332 to rotate, causing the positioning cover 3331 to rotate synchronously. The telescopic ends of each telescopic rod 33342a in the rotating assembly 3334 are extended to a corresponding distance according to the different rotation speeds of the positioning cover 3331 under the drive of the sliding block 33342b. At this time, each connecting rod 33343 drives the rotating disk 33341 to rotate together under the drive of the telescopic end of the corresponding telescopic rod 33342a. At the same time, the rotating disk 33341 drives the transmission cover 3335 to rotate synchronously. Finally, the fan blades 3332 rotate synchronously with respect to the fixed hole 33313 under the drive of the transmission cover 3335 to suppress the air flow caused by the high-speed rotation of the cold air mechanism 333 During the entire operation process, the speed may be adjusted as needed. When the speed of the rotating drive shaft 332 decreases, the telescopic ends of the telescopic rods 33342a in the rotating assembly 3334 are pulled back by their own tension return springs, driving the sliding blocks 33342b to retract together. At this time, the connecting rods 33343, driven by the output ends of the corresponding telescopic rods 33342a, jointly drive the rotating disk 33341 to reverse and reset. At the same time, the rotating disk 33341 drives the transmission cover 3335 to rotate synchronously. Finally, each fan blade 3332, driven by the transmission cover 3335, undergoes a synchronous angular reset rotation relative to the fixed hole 33313 to ensure that more air is delivered to the cooling box 31, thereby maintaining the temperature inside 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 drive motor 331 and the angle of the fan blades 3332, it can adapt to the quenching requirements of profiles of 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.
