Description

Technical Field

[0001] The utility model relates to the technical field of metal heat treatment, in particular to a water mist cooling quenching structure. Background Art

[0002] Quenching is generally used to refer to the solution treatment or heat treatment process with rapid cooling of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass. The main purpose of quenching is to retain the metastable solid solution formed at the solution temperature to a lower temperature (room temperature) as much as possible through rapid cooling. When the quenching cooling rate is fast enough, a supersaturated solid solution can be obtained. Through natural aging at room temperature or artificial aging at an appropriate temperature, a uniform solute atom precipitation zone (coherent or semi-coherent) is formed in the matrix, thereby strengthening the alloy and other materials.

[0003] The most commonly used cooling medium for quenching aluminum alloys is water, which is quenched by immersion or water spraying. Due to its high heat of vaporization and specific heat capacity, water has a high quenching capacity (thermal conductivity). However, due to the high cooling rate of water cooling, quenching using immersion or water spraying can easily lead to uneven cooling across the workpiece, which can easily cause deformation.

[0004] Therefore, water mist cooling is currently widely used to reduce the deformation of thin plate products. However, most of the water mist nozzles currently used in the market are used for spraying. Because the water mist particles sprayed by the water mist nozzles are too large, they also cause uneven cooling of the workpiece, which in turn cannot meet production needs.

[0005] Therefore, the above problems need to be solved urgently. Utility Model Content

[0050] This embodiment proposes a water mist cooling quenching structure suitable for water mist cooling of a workpiece, so as to blow the water mist evenly onto the surface of the workpiece, thereby ensuring uniformity in cooling the temperature of all parts of the workpiece.

[0051] Specifically, see Figure 1The water mist cooling and quenching structure comprises a atomizing box 1, an atomizing head 2, a pipeline 3 and a fan 4. The atomizing box 1 is used for containing quenching solution. The atomizing head 2 is arranged in the atomizing box 1 and used for atomizing the quenching solution. The pipeline 3 is arranged inside the atomizing box 1 and above the liquid level of the quenching solution. The outer peripheral wall of the pipeline 3 is uniformly provided with filter ports 31. The fan 4 comprises an air inlet and an air outlet. The air inlet is communicated with the pipeline 3. The air outlet is arranged opposite to the workpiece 100.

[0052] It can be understood that the atomizing head 2 can atomize the quenching solution in the atomizing box 1. During the operation of the fan 4, the atomized quenching solution can be sucked into the pipeline 3 through the filter ports 31. The filter ports 31 can filter the atomized water mist particles to improve the uniformity of the water mist particles. The filtered water mist can be transported to the air outlet under the action of the fan 4. The air uniformizing member uniformly arranged at the air outlet can separate the water mist to ensure that the separated water mist is uniformly transported to each part of the workpiece 100, thereby ensuring the uniformity of the quenching and cooling of each part of the workpiece 100. Preferably, the quenching solution is water. In some other feasible embodiments, the quenching solution can also be other cooling medium, which is not described herein.

[0053] It should be noted that the atomizing head 2 is preferably an ultrasonic atomizing head, which can further atomize the quenching solution into fine mist droplets, thereby further avoiding that the water mist particles discharged from the air outlet are too large, and further improving the uniformity of the quenching and cooling of each part of the workpiece 100.

[0054] It should be further noted that the air uniformizing member is preferably an air knife. The air knife uniformly arranged at the air outlet can separate the air outlet into multiple air outlet pipelines to ensure the separation of the water mist, thereby ensuring that the water mist is uniformly transported to each part of the workpiece 100, and further ensuring the uniformity of the quenching and cooling of each part of the workpiece 100.

[0055] Please refer to Figure 2 In the embodiment, the pipeline 3 comprises multiple pipe bodies 32 which are sequentially communicated. Adjacent two pipe bodies 32 are detachably connected. The pipe bodies 32 at both ends are detachably connected with the side wall of the atomizing box 1. The filter ports 31 are uniformly arranged on all or part of the pipe bodies 32. It can be understood that the detachable pipe bodies 32 are convenient for replacing the pipe bodies 32, thereby different pipe bodies 32 can be replaced according to actual needs to adjust the amount of mist blown by the fan 4. That is, according to different needs, the pipe body 32 with the filter port 31 or the pipe body 32 without the filter port 31 is selected, thereby adjusting the amount of mist entering the pipeline 3 without changing the overall length of the pipeline 3, to improve the applicability of the water mist cooling and quenching structure.

[0056] Particularly, the two ends of the pipe body 32 are respectively provided with a flange 321, and the flanges 321 between the adjacent two pipe bodies 32 are connected by bolts. In this way, the pipe body 32 is installed.

[0057] Further, one end of the pipeline 3 away from the fan 4 is an air inlet 33, and the air inlet 33 penetrates the atomizing box 1; the water mist cooling and quenching structure further comprises a cover plate, the cover plate covers the air inlet 33, and the cover plate is used to adjust the opening degree of the air inlet 33. It can be understood that by controlling the opening and closing degree of the cover plate and the air inlet 33, the amount of mist and the proportion of air inside the pipeline 3 can be controlled, and thus the amount of mist in the pipeline 3 can be controlled.

[0058] Illustratively, the cover plate is slidingly arranged on the atomizing box 1, and the cover plate can cover the air inlet 33 during sliding, thereby adjusting the opening and closing degree of the air inlet 33 to control the amount of mist in the pipeline 3.

[0059] In this embodiment, one fan 4 and one pipeline 3 form a cooling assembly, and a plurality of cooling assemblies are arranged, and the plurality of cooling assemblies are respectively opposite to different quenching surfaces of the workpiece 100. It can be understood that the plurality of cooling assemblies can simultaneously cool the different quenching surfaces of the workpiece 100, thereby further ensuring uniform cooling of the workpiece 100, and thus avoiding deformation of the workpiece 100 during quenching and cooling.

[0060] Illustratively, taking an aluminum alloy sheet workpiece 100 as an example, the aluminum alloy sheet workpiece 100 has two quenching surfaces, and thus the number of cooling assemblies is two, and the fans 4 of the two cooling assemblies are respectively arranged opposite to the two quenching surfaces, so as to simultaneously quench and cool the two quenching surfaces.

[0061] It should be noted that the water mist cooling and quenching structure proposed in this embodiment can not only be used for water mist cooling of aluminum alloy sheet workpieces 100, but also be used for water mist cooling of other workpieces 100, which will not be described here.

[0062] Please refer to Figure 3 and Figure 4 for reference. In this embodiment, the water mist cooling and quenching structure further comprises a rack frame 5 and a fixing frame 6, the rack frame 5 is used to fix the workpiece 100; the fixing frame 6 is arranged opposite to the air outlet, and the fixing frame 6 is used to fix the rack frame 5 and make the workpiece 100 opposite to the air outlet. It can be understood that during heating of the workpiece 100, the rack frame 5 is used to fix the workpiece 100, after heating is completed, the rack frame 5 is moved together with the workpiece 100 to the water mist cooling and quenching structure, and the rack frame 5 is arranged on the skeleton, so as to cool the workpiece 100. In addition, in order to move the rack frame 5, a handle is arranged on the top of the rack frame 5.

[0063] It should be noted that the structure of the rack frame 5 can be modified to adapt to different shapes of workpieces 100, and can also be used for water mist cooling of other material workpieces 100, thereby further improving the applicability of the water mist cooling and quenching structure.

[0064] In this embodiment, the fixing frame 6 includes a first frame body 61, a second frame body 62, a third frame body 63, and a fourth frame body 64. The first frame body 61 is arranged along the height direction. The second frame body 62 is arranged along the first horizontal direction, and is arranged on the first frame body 61. The height of the second frame body 62 is adjustable. The third frame body 63 and the fourth frame body 64 are arranged on the top of the second frame body 62 along the second horizontal direction, and the third frame body 63 and the fourth frame body 64 are combined to form a vertical sliding groove adapted to the rack frame 5. It can be understood that the first frame body 61 is a door-shaped frame. Two second frame bodies 62 are arranged on the two sides of the first frame body 61. One third frame body 63 and one fourth frame body 64 form a set of limiting structures. Two sets of limiting structures are arranged on the two second frame bodies 62 to ensure the stability of the rack frame 5 when fixed on the fixing frame 6.

[0065] In addition, the height of the second frame body 62 is adjustable, so that the height of the second frame body 62 can be adjusted according to different models of workpieces 100, thereby further ensuring uniform cooling of the workpiece 100 at all positions, and further improving the applicability of the water mist cooling and quenching structure.

[0066] Exemplarily, a plurality of first adjusting holes 611 are uniformly distributed on the first frame body 61 along the height direction. The second frame body 62 is connected to different first adjusting holes 611 by bolts, so that the height of the second frame body 62 can be adjusted.

[0067] Further, the distance between the air outlet of each fan 4 and the corresponding quenching surface is adjustable. It can be understood that if the model of the workpiece 100 increases, the position of the workpiece 100 will not be covered by the water mist, thereby causing uneven cooling of the workpiece 100 at all positions. If the model of the workpiece 100 decreases, the water mist will be wasted. Therefore, after the model of the workpiece 100 is changed, the distance between the air outlet and the corresponding quenching surface needs to be adjusted.

[0068] Exemplarily, the water mist cooling and quenching structure further includes a bottom plate 8. A plurality of second adjusting holes 81 are arranged on the bottom plate 8 along the second horizontal direction. The fan 4 is connected to different second adjusting holes 81 by bolts, so that the distance between the air outlet and the corresponding quenching surface can be adjusted.

[0069] In addition, in order to adapt to the adjustment of the position of the fan 4, a threaded tube 7 is provided between the air inlet and the pipe 3. When the position of the fan 4 is adjusted, the threaded tube 7 can adapt and expand, thereby avoiding the movement of the atomizer box 1.

[0070] See also Figure 5 In this embodiment, the atomizing box 1 includes a box body 11 and a box cover 12. The box body 11 and the box cover 12 can be assembled to form a storage space; the box cover 12 is provided with a vent hole 13. It is understood that before the workpiece 100 is cooled and quenched, the box cover 12 and the box body 11 are first assembled to form a relatively closed storage space to facilitate the storage of water mist, thereby further ensuring the uniformity of the workpiece 100 during cooling and quenching. The vent hole 13 prevents the storage space from developing a negative pressure state, thereby ensuring the continuity of the quenching process.

[0071] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
