Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for metallic materials, and in particular to a steel pipe atomizing spray device for a normalizing cooling bed. Background Technology

[0002] Normalizing is a heat treatment process in which steel is heated to 30-50°C above hypoeutectoid or hypereutectoid steel, held at that temperature, and then air-cooled. It refines the grains, makes the microstructure uniform, improves mechanical properties, eliminates microstructural defects after casting and forging, reduces hardness, and improves machinability. For low-carbon steel, it can increase strength, and for hypereutectoid steel, it can eliminate network carbides, preparing for subsequent quenching. Its significance lies in balancing the strength, plasticity, and toughness of steel by optimizing the microstructure. It is widely used in machinery manufacturing as a preparatory or final heat treatment.

[0003] Normalizing is a process that involves heating steel above its critical point and then air-cooling it to refine the grains, homogenize the microstructure, eliminate defects from casting or forging, reduce the hardness of the material to improve machinability, adjust the strength of low-carbon steel, or eliminate network carbides in hypereutectoid steel. Its significance lies in optimizing the mechanical properties of steel, balancing strength and toughness, and laying the foundation for subsequent processing or heat treatment. It is widely used as a preparatory or final processing technology in machinery manufacturing to improve product quality and processing efficiency.

[0004] In existing technologies, the normalizing process for heat-treated steel pipes involves heating the steel pipe to the required temperature in a quenching furnace, then directly placing it into a cooling bed without water for passive cooling with ambient air. Due to environmental factors, the cooling rate of ambient air is slow, and the cooling rate of the steel pipe may vary significantly, resulting in uneven microstructure and properties. The core of thick-walled steel pipes cools slowly, which can easily lead to the formation of coarse pearlite or bainite, reducing toughness and causing the steel pipe to fail to meet performance standards. To address these issues, a steel pipe atomizing spray device for the normalizing cooling bed is proposed. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a steel pipe atomizing spray device for normalizing cooling beds, which aims to improve the problems of slow cooling speed and different cooling rates of steel pipes in the prior art, resulting in uneven microstructure and properties.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A steel pipe atomizing spray device for a normalizing cooling bed includes a base plate, a plurality of support plates fixedly connected to the top of the base plate, a plurality of steel pipe frames fixedly connected to adjacent sides of the plurality of support plates, a plurality of adjustment mechanisms installed on the inner walls of the plurality of steel pipe frames, and a cooling bed body fixedly connected to the top of the base plate.

[0008] The adjustment mechanism includes a connecting pipe, a water pipe fixedly connected to the top of the connecting pipe, an air pipe fixedly connected to the inner wall of the connecting pipe, a nozzle rotatably connected to the inner wall of the connecting pipe, and an adjustment component installed on the inner wall of the connecting pipe.

[0009] Furthermore, the adjustment assembly includes a fixed plate, a sealing ring is fixedly connected to the top of the fixed plate, a plurality of sliding columns are slidably connected to the inner wall of the fixed plate, a plurality of adjustment plates are fixedly connected to the bottom of the plurality of sliding columns, and a plurality of sliders are fixedly connected to the bottom of the plurality of adjustment plates.

[0010] Furthermore, the outer wall of the fixed disk is rotatably connected to a rotating disk, and the inner wall of the rotating disk is provided with a sliding groove.

[0011] Furthermore, the outer wall of the air pipe is detachably connected to the inner wall of the steel pipe frame, and the outer wall of the water pipe is detachably connected to the inner wall of the steel pipe frame.

[0012] Moreover, the outer wall of the fixed disk is fixedly connected to the inner wall of the connecting tube, and the outer walls of the plurality of sliders are slidably connected to the inner wall of the rotating disk.

[0013] Moreover, the outer wall of the connecting pipe is fixedly connected to the inner wall of the steel pipe frame, and the outer walls of the plurality of sliders are slidably connected to the inner wall of the sliding groove.

[0014] Furthermore, the bottom of the plurality of adjustment plates is slidably connected to the top of the rotating disk, and the bottom of the rotating disk is fixedly connected to the top of the nozzle;

[0015] Furthermore, the outer wall of the sealing ring is fixedly connected to the inner wall of the connecting pipe, and the outer wall of the rotating disk is rotatably connected to the inner wall of the connecting pipe.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, rotating the nozzle drives the rotating disk, and the sliding groove on its inner wall drives the slider, thereby causing the adjusting plate and the sliding column to slide from the inside to the outside along the inner wall of the fixed disk. The gap between the adjusting plates, which were originally close together, gradually widens, the resistance to flow through the adjusting plate decreases, and the spray flow increases. Conversely, the sliding column slides from the outside to the inside, causing the gap between the adjusting plates to narrow, the flow resistance to increase, and the spray flow to decrease. This structure can accurately and conveniently adjust the spray flow and flexibly change the spray volume to meet the needs of different scenarios. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides an embodiment of a steel pipe atomizing spray device for a normalizing cooling bed, comprising a base plate 1. The base plate 1 serves as the basic load-bearing component of the entire device, providing an installation platform for all components such as the support plate 2 and the cooling bed body 5 above, ensuring the stability of each component. Multiple support plates 2 are fixedly connected to the top of the base plate 1. The support plates 2 are used to support the steel pipe frame 3 to ensure the stability of the overall structure. Multiple steel pipe frames 3 are fixedly connected to adjacent sides of the multiple support plates 2. The steel pipe frames 3 provide an installation carrier for the adjustment mechanism 4 and enhance the structural rigidity. Multiple adjustment mechanisms 4 are installed on the inner walls of the multiple steel pipe frames 3. The adjustment mechanism 4 can achieve precise adjustment of the spray flow rate through the cooperation of internal components.

[0027] A cooling bed body 5 is fixedly connected to the top of the base plate 1. The cooling bed body 5 is the target of spray cooling. The spray from the regulating mechanism 4 can cool it. The regulating mechanism 4 includes a connecting pipe 41, which is a space where cooling water and compressed air converge and mix to provide a channel for spray formation. A water pipe 42 is fixedly connected to the top of the connecting pipe 41. The water pipe 42 delivers cooling water to the connecting pipe 41 to participate in the mixing with compressed air. An air pipe 43 is fixedly connected to the inner wall of the connecting pipe 41. The air pipe 43 delivers compressed air to the connecting pipe 41 to mix with cooling water. A nozzle 44 is rotatably connected to the inner wall of the connecting pipe 41. Rotating the nozzle 44 can drive the rotating disk 456 to rotate synchronously, thereby activating the flow regulation function. An regulating component 45 is installed on the inner wall of the connecting pipe 41. The regulating component 45 changes the flow resistance through the relative movement of each component to achieve spray flow regulation.

[0028] The adjusting assembly 45 includes a fixed plate 451, which provides a sliding track for the sliding column 453 to ensure the stable movement of the adjusting plate 454. A sealing ring 452 is fixedly connected to the top of the fixed plate 451. The sealing ring 452 can prevent fluid leakage in the connecting pipe 41 and ensure stable spray pressure. Multiple sliding columns 453 are slidably connected to the inner wall of the fixed plate 451. The sliding columns 453 can drive the adjusting plate 454 to change position by sliding along the inner wall of the fixed plate 451. Multiple adjusting plates 454 are fixedly connected to the bottom of the multiple sliding columns 453. The change in the gap between the adjusting plates 454 will change the fluid flow resistance and thus adjust the spray flow rate.

[0029] Multiple sliders 455 are fixedly connected to the bottom of multiple adjusting plates 454. The sliders 455 can move synchronously within the sliding grooves 457 to ensure consistent adjustment. A rotating disk 456 is rotatably connected to the outer wall of the fixed disk 451. When the rotating disk 456 rotates, it drives the sliders 455 to move through the sliding grooves 457 to change the position of the adjusting plates 454. The inner wall of the rotating disk 456 has a sliding groove 457, which provides a path for the sliders 455 to move, converting the rotational motion of the rotating disk 456 into the linear motion of the sliders 455. The outer wall of the air pipe 43 is detachably connected to the inner wall of the steel pipe frame 3.

[0030] The outer wall of the water pipe 42 is detachably connected to the inner wall of the steel pipe frame 3. The outer wall of the fixed plate 451 is fixedly connected to the inner wall of the connecting pipe 41. The outer walls of multiple sliders 455 are slidably connected to the inner wall of the rotating plate 456. The outer wall of the connecting pipe 41 is fixedly connected to the inner wall of the steel pipe frame 3. The outer walls of multiple sliders 455 are slidably connected to the inner wall of the sliding groove 457. The bottom of multiple adjusting plates 454 is slidably connected to the top of the rotating plate 456. The bottom of the rotating plate 456 is fixedly connected to the top of the nozzle 44. The outer wall of the sealing ring 452 is fixedly connected to the inner wall of the connecting pipe 41. The outer wall of the rotating plate 456 is rotatably connected to the inner wall of the connecting pipe 41.

[0031] Working principle: When the spray flow needs to be adjusted, rotating the nozzle 44 drives the rotating disk 456 to rotate synchronously. The sliding groove 457 on the inner wall of the rotating disk 456 then moves the slider 455 in the groove, which in turn drives the adjusting plate 454 and the sliding column 453 to slide from the inside to the outside along the inner wall of the fixed disk 451. The gap between the adjusting plates 454, which was originally close, gradually widens. At this time, the cooling water delivered by the water pipe 42 and the compressed air delivered by the air pipe 43 converge in the connecting pipe 41, and the resistance to flow through the adjusting plate 454 decreases, thus increasing the spray flow. Conversely, the sliding column 453 slides from the outside to the inside, causing the gap between the adjusting plates 454 to narrow, increasing the flow resistance, and thus decreasing the spray flow. This structure realizes precise and convenient adjustment of the spray flow, and can flexibly change the spray volume according to actual needs, meeting the usage requirements in different scenarios.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
