Description

Technical Field

[0001] This utility model relates to the technical field of rapid cooling forming devices, and in particular to a rapid cooling forming device for high-manganese and high-chromium heat-resistant steel. Background Technology

[0002] According to the search, a rapid cooling device for thermoforming equipment with publication number CN221437211U can buffer heat dissipation between the mold and water by using heat sinks and fans together, so as to avoid damage to the mold from direct contact with cold water. The heat sink is opened on both sides of the cooling box. When the material is placed in the inner cavity of the mold, the heat sink in the heat sink will absorb the temperature. At this time, the fan starts to rotate and drives the air flow around the device. The heat absorbed by the heat sink 17 can then exchange heat with the air.

[0003] In the process of developing this invention, the inventors discovered at least the following problems in the prior art: High-manganese, high-chromium heat-resistant steel is at a high temperature immediately after leaving the forming equipment. If placed in an inner cavity with heat sinks, a significant temperature difference between the steel and the heat sinks causes a large amount of heat to be rapidly transferred to the heat sinks, leading to a sharp rise in the heat sink temperature. The heat sinks primarily rely on heat conduction for heat dissipation. However, when the heat sink temperature rises to near the ambient temperature, reaching thermal equilibrium, its heat conduction capacity decreases significantly, even approaching zero. Furthermore, simply relying on a fan to blow air for heat exchange with the heat sink is also inefficient. This is because air has low thermal conductivity; with limited flow rate and contact area, relatively little heat is removed per unit time through convection, making it difficult to meet the need for rapidly reducing the temperature of the high-manganese, high-chromium heat-resistant steel and the heat sinks.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model proposes: a rapid cooling and forming device for high manganese and high chromium heat-resistant steel, including a reaction box, wherein the reaction box is provided with a segmented cooling structure on the outside and inside, and an auxiliary cooling structure is provided on the top of the reaction box;

[0006] The segmented cooling structure includes mounting frames installed on the front and back of the reaction chamber, a water tank assembled inside the mounting frames, and two symmetrically distributed central cooling boxes installed on the inner wall of the reaction chamber. The top of each central cooling box is equipped with equidistantly distributed atomizing nozzles, and the bottom of each atomizing nozzle is connected to an extension pipe.

[0007] Preferably, two symmetrically distributed electric telescopic rods are installed in the middle of the two collection boxes and on the inner bottom wall of the reaction box.

[0008] Preferably, a template placement frame is installed on the top of the two electric telescopic rods, and the inner wall of the template placement frame is provided with filter holes.

[0009] Preferably, the auxiliary cooling structure includes two electric slide rails installed on the front and back of the reaction chamber and located above the mounting frame, an electric slider slidably connected to the inner wall of the electric slide rails, and a fixed frame fixedly connected to the electric slider.

[0010] Preferably, four connecting posts are installed on the top of the fixed frame, and a fan assembly is installed on the top of the four connecting posts.

[0011] Preferably, the interior of the fixed frame is equipped with linearly distributed heat dissipation copper pipes, and the inner wall of the reaction chamber and one side of one of the electric telescopic rods are equipped with a switch button for controlling the electric slider.

[0012] Preferably, a booster pump is installed on the top of the water tank. The input end of the booster pump is connected to a water pumping pipe and the output end is connected to a water delivery pipe. The other end of the water pumping pipe extends into the water tank, and the other end of the water delivery pipe extends into the collection tank. The bottom of the extension pipe also extends into the collection tank and is located directly below the atomizing nozzle.

[0013] The beneficial effects of this utility model are:

[0014] Through the segmented cooling structure design, the high-manganese and high-chromium heat-resistant steel is placed in the template placement frame immediately after the forming process is completed. Then, the booster pump is started, and with the help of external pressurization, water in the water tank is drawn and sprayed out through the atomizing nozzle. At this time, the atomized water is sprayed at high speed onto the surface of the steel part, and it vaporizes rapidly upon contact with the high-temperature steel part. This process absorbs a large amount of heat, thereby achieving rapid cooling. Since the thermal stress of the steel part is relatively small when it is in a high-temperature state, this rapid cooling method will not cause excessive damage to the steel part. On the contrary, it can effectively improve production efficiency while ensuring the quality of the steel part.

[0015] Simultaneously, the auxiliary cooling structure works in conjunction with the segmented cooling structure. After the high-manganese high-chromium heat-resistant steel is cooled by atomized spraying and its temperature initially decreases, the electric telescopic rod is activated, driving the template placement frame and the high-manganese high-chromium heat-resistant steel inside the frame to move downwards. During the downward movement of the electric telescopic rod, the template placement frame touches the switch button. This touch triggers the electric slide rail and electric slider to start working, causing the two fixed frames to move towards the center until they fit together. At the same time, the fan group is activated. At this point, the hot air emitted by the high-manganese high-chromium heat-resistant steel comes into contact with the heat dissipation copper pipe during its ascent. The fan group accelerates the airflow, enabling the hot air to enter and exit the heat dissipation copper pipe more quickly. Since the temperature of the high-manganese high-chromium heat-resistant steel has already initially decreased, this treatment method can perform secondary cooling, thus allowing it to smoothly enter the low-temperature slow cooling stage.

[0023] The following will be combined with the appendix Figure 1 To be continued Figure 5The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly. Example

[0025] Please see Figure 1 - Figure 5 As shown, this embodiment provides a rapid cooling and forming device for high manganese and high chromium heat-resistant steel, including a reaction chamber 1, a segmented cooling structure 2 provided outside and inside the reaction chamber 1, and an auxiliary cooling structure 3 provided above the reaction chamber 1.

[0026] The segmented cooling structure 2 includes a mounting frame 21 installed on the front and back of the reaction chamber 1, a water tank 22 assembled inside the mounting frame 21, and two symmetrically distributed central boxes 23 installed on the inner wall of the reaction chamber 1. The top of the central box 23 is equipped with equidistant atomizing nozzles 24, and the bottom of the atomizing nozzles 24 is connected to an extension pipe.

[0027] Considering the high temperature of high-manganese and high-chromium heat-resistant steel after forming, the booster pump 27 is activated to draw water from the water tank 22 and spray it out through the atomizing nozzle 24 with the help of external pressurization. At this time, the atomized water is sprayed at high speed onto the surface of the steel part and rapidly vaporizes upon contact with the high-temperature steel part. This process absorbs a large amount of heat, thereby achieving rapid cooling. Since the thermal stress of the steel part is relatively small when it is in a high-temperature state, this rapid cooling method will not cause excessive damage to the steel part. On the contrary, it can effectively improve production efficiency while ensuring the quality of the steel part. Example

[0028] like Figure 4 - Figure 5As shown, two symmetrically distributed electric telescopic rods 25 are installed in the middle of the two central boxes 23 and on the inner bottom wall of the reaction box 1. The electric telescopic rods 25 are waterproof. A template placement frame 26 is installed on the top of the two electric telescopic rods 25. The inner wall of the template placement frame 26 has filter holes. Water generated during the cooling process can flow into the inner bottom wall of the reaction box 1 through the filter holes. The reaction box 1 is provided with a discharge pipe for draining wastewater. The auxiliary cooling structure 3 includes two electric slide rails 31 installed on the front and back of the reaction box 1 and above the mounting frame 21, and an electric slider 32 slidably connected to the inner wall of the electric slide rails 31, and a fixed frame 33 fixedly connected to the electric slider 32. Four connecting columns 34 are installed on the top of the fixed frame 33, and a fan group 35 is installed on the top of the four connecting columns 34. The interior of the fixed frame 33 is equipped with linearly distributed heat dissipation copper pipes 36. The inner wall of the reaction box 1 and one of the electric telescopic rods 25 is located on the inner bottom wall of the reaction box 1. A switch button 37 for controlling the electric slider 32 is installed on one side of the rod 25. The switch button 37 controls the electric slider 32 and the electric slide rail 31. This control method is existing technology. By moving the template placement frame 26 downward, it contacts the switch button 37. Then, the switch button 37 controls the electric slide rail 31 and the electric slider 32, causing the two fixed frames 33 to move towards the center. After cooling, the fixed template placement frame 26 moves upward and contacts the switch button 37 again, causing it to control the electric slider 32 and the electric slide rail 31, causing the two fixed frames 33 to move and unfold to both sides. A booster pump 27 is installed on the top of the water tank 22. The input end of the booster pump 27 is connected to the water suction pipe 28 and the output end is connected to the water delivery pipe 29. The other end of the water suction pipe 28 extends into the water tank 22, and the other end of the water delivery pipe 29 extends into the collection box 23. The bottom of the extension pipe also extends into the collection box 23 and is located directly below the atomizing nozzle 24.

[0029] The auxiliary cooling structure 3 works in conjunction with the segmented cooling structure 2. After the high-manganese high-chromium heat-resistant steel is cooled by atomized spraying and its temperature is initially reduced, the electric telescopic rod 25 is activated, driving the template placement frame 26 and the high-manganese high-chromium heat-resistant steel inside the frame to move downwards. During the downward movement of the electric telescopic rod 25, the template placement frame 26 touches the switch button 37. This touch triggers the electric slide rail 31 and the electric slider 32 to start working, causing the two fixed frames 33 to move towards the center until they fit together. At the same time, the fan group 35 is activated. At this time, the hot air emitted by the high-manganese high-chromium heat-resistant steel comes into contact with the heat dissipation copper pipe 36 during its ascent. The fan group 35 accelerates the air circulation, enabling the hot air to enter and exit the heat dissipation copper pipe 36 more quickly. Since the temperature of the high-manganese high-chromium heat-resistant steel has already been initially reduced, this treatment method can perform secondary cooling, thus allowing it to smoothly enter the low-temperature slow cooling stage.

[0030] Work steps;

[0031] First, the newly formed high-manganese, high-chromium heat-resistant steel is placed on the template placement frame 26 inside the reaction chamber 1. At this time, both the segmented cooling structure 2 and the auxiliary cooling structure 3 are in standby mode. Then, the booster pump 27 installed on top of the water tank 22 is started, drawing water from the water tank 22 through the water extraction pipe 28 and sending it to the central tank 23 through the water delivery pipe 29. Then, atomized water is sprayed at high speed from the equidistantly distributed atomizing nozzles 24 on the top of the central tank 23, spraying it onto the surface of the steel part. The water vaporizes and absorbs heat to achieve rapid cooling. Because the thermal stress of the steel part is small at high temperatures, this... The operation ensures quality and improves efficiency. After the steel parts are initially cooled by atomized spraying, the electric telescopic rod 25 is activated, which moves the template placement frame 26 and the steel parts downward. During the downward movement, the template placement frame 26 touches the switch button 37, triggering the electric slide rail 31 and the electric slider 32, causing the two fixed frames 33 to move towards the center and fit together. At the same time, the fan group 35 is activated, and the hot air rises and comes into contact with the heat dissipation copper pipe 36 inside the fixed frame 33. The fan accelerates the air circulation, which performs secondary cooling on the initially cooled steel parts, helping them enter the low-temperature slow cooling stage.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
