[0002] In the production of aluminum profiles, quenching is a crucial step, aiming to rapidly cool the aluminum profiles to achieve the desired mechanical properties and microstructure. Traditional aluminum profile quenching methods mostly employ water cooling with a single cooling intensity. During quenching, the inconsistent cooling rates across different parts of the aluminum profile lead to significant internal deformation stress, easily causing bending, twisting, and other deformation problems, severely affecting the dimensional accuracy and surface quality of the aluminum profile. While some equipment attempts to achieve gradient cooling, its low control precision makes it difficult to achieve stable and controllable gradient cooling effects. Utility Model Content

[0021] 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. Example 1

[0022] Please see Figures 1-5 This utility model discloses a multi-stage gradient water-cooling quenching mechanism for aluminum profiles, including a side frame 1 and a protective cover 2 fixed to the side frame 1 by screws, and also includes a multi-stage gradient quenching component 3, a quenching control component 4, and a water-cooling circulation component 5, wherein:

[0023] A control box 6 is provided on one side of the side frame 1, and quenched aluminum profiles 7 are provided between the side frames 1;

[0024] Please refer to the appendix. Figure 3 The multi-stage gradient quenching assembly 3 includes a quenching main pipe 31, a flow control valve 32, a quenching branch pipe 33, and a quenching nozzle 34. The quenching nozzle 34 is installed at one end of the quenching branch pipe 33 and is set to face downwards. The quenching branch pipe 33 is connected to one side of the quenching main pipe 31 and is set at equal intervals.

[0025] Please refer to the appendix. Figure 4The quenching control component 4 includes an infrared temperature sensor 41, an isolation plate 42, a rotating roller 43, a rotating shaft 44, and a transmission component. Several infrared temperature sensors 41 are provided and fixed at equal intervals to the top of the protective cover 2 by screws. The isolation plate 42 is located between the infrared temperature sensors 41, and the rotating roller 43 is located on the rotating shaft 44. Specifically, the isolation plate 42 can separate the radiation reception between the infrared temperature sensors 41 at each level to avoid mutual interference.

[0026] The quenching main pipeline 31 includes a primary quenching pipeline 311, a secondary quenching pipeline 312, and a tertiary quenching pipeline 313, with one end of each pipeline connected to a flow control valve 32 via a flange. The quenching main pipeline 31 is fixed to the inner wall of the protective cover 2 with screws.

[0027] The flow control valve 32 is electrically connected to the control box 6, and the control box 6 is electrically connected to the infrared temperature sensor 41. The isolation plate 42 is arranged side by side with the flow control valve 32 and perpendicular to the movement direction of the quenched aluminum profile 7.

[0028] The transmission components include a drive motor 45, a main gear 46, a secondary gear 47, a drive wheel 48, and a drive belt 49. The main gear 46 is fixed to one end of the drive motor 45, and the main gear 46 meshes with the secondary gear 47. The drive motor 45 is electrically connected to the control box 6.

[0029] The secondary gear 47 is welded onto the rotating shaft 44. The rotating shaft 44 is provided with several side frames 1 that rotate and fit at both ends. A transmission wheel 48 is welded to one end of the rotating shaft 44. A transmission belt 49 is nested between the transmission wheels 48. Specifically, the transmission motor 45 drives the main gear 46 to rotate, which in turn drives the rotating shaft 44 on the secondary gear 47 to rotate. The rotating shaft 44 transports the aluminum profile into the protective cover 2 through the rotating roller 43. The rotating roller 43 is controlled to move at a uniform speed by the control box 6 to ensure that the aluminum profile is cooled evenly during the cooling process.

[0030] In this embodiment, when the quenched aluminum profile enters each quenching and cooling zone, the emitted heat radiation is received in real time by the infrared temperature sensor 41 at the top, thereby continuously monitoring the temperature change of the aluminum profile and feeding the temperature data back to the control box 6. According to the temperature-flow rate curve, when the temperature of the aluminum profile is detected to be higher than the preset value, the control box 6 automatically increases the opening of the flow control valve 32 of the corresponding cooling unit to increase the cooling water flow rate; when the temperature is lower than the preset value, it decreases the opening of the flow control valve to reduce the cooling water flow rate, thereby achieving precise gradient cooling control. Example 2

[0031] Based on the above embodiment 1, please refer to the appendix. Figure 5 The water-cooled circulation assembly 6 includes a bottom groove 51, which is located below the rotating roller 43. The quenched aluminum profile 7 is placed on the rotating roller 43, and a water pump 52 is connected to one side of the bottom groove 51 through a pipe.

[0032] The water pump 52 is connected to the spiral tube 53 through a pipe. A cooling fan 54 is located directly above the spiral tube 53 and is welded to the shelf 55.

[0033] In this embodiment, the water sprayed to cool the quenched aluminum profile 7 is heated and leaks into the bottom tank 51 below, where it mixes with other cold water and cools naturally. Then, it is drawn by the water pump 52 and flows through the spiral tube 53, where it is efficiently cooled by the cooling fan 54, and finally re-enters the quenching main pipe 31 for cooling.

[0034] The working principle and usage process of this utility model: When using this equipment, firstly, according to the specifications, alloy composition and other parameters of the aluminum profile to be quenched, the initial cooling water flow rate and temperature-flow rate curve of each flow control valve 32 are set through the control box 6. Then, the water pump 52 is turned on to pump the cold water in the bottom tank 51 into the quenching main pipe 31. The cold water passes through the first-stage quenching pipe 311, the second-stage quenching pipe 312 and the third-stage quenching pipe 313 in sequence, and is then introduced into the quenching branch pipe 33 and sprayed out from the quenching nozzle 34 to the rotating roller 43.

[0035] The high-temperature aluminum profile after processing is then placed on the rotating roller 43. The drive motor 45 is then started, which drives the main gear 46 to rotate, which in turn drives the rotating shaft 44 on the secondary gear 47 to rotate. The rotating shaft 44 transports the aluminum profile into the protective cover 2 through the rotating roller 43 and moves at a constant speed, and is then sprayed out by the quenching nozzle 34 for cooling and quenching.

[0036] When the quenched aluminum profile enters each quenching and cooling zone, the heat radiation emitted is received in real time by the infrared temperature sensor 41 at the top, thereby continuously monitoring the temperature change of the aluminum profile and feeding the temperature data back to the control box 6. According to the temperature-flow rate curve, when the temperature of the aluminum profile is detected to be higher than the preset value, the control box 6 automatically increases the opening of the flow control valve 32 of the corresponding cooling unit to increase the cooling water flow rate; when the temperature is lower than the preset value, it decreases the opening of the flow control valve to reduce the cooling water flow rate, thereby achieving precise gradient cooling control.

[0037] When the aluminum profile is in the primary quenching pipes 311, the temperature is relatively high. A large flow of cold water is controlled by the flow control valve 32 to quickly remove a large amount of heat using strong cooling intensity. As the aluminum profile moves and cools down, when it passes through the secondary quenching pipes 312, the spray flow rate is reduced by the flow control valve 32 in this area, thereby reducing the cooling intensity. This makes the overall cooling process more in line with the natural temperature decay rhythm of the aluminum profile, and makes the heat dissipation rate of each part at different stages more coordinated. Through the uniform reduction of cooling intensity, it can avoid excessive temperature difference caused by excessively rapid cooling in some areas, thereby reducing thermal stress concentration and avoiding deformation caused by uneven stress. Indirectly, it also makes the cooling rate of each part more consistent in terms of stress influence, ensuring the quality of the aluminum profile.
