Description

Technical Field

[0001] This utility model relates to a multi-mode aluminum profile quenching device, belonging to the field of aluminum quenching technology. Background Technology

[0002] With the increasing demand for aluminum profiles from industries such as construction, transportation, and electronics, especially in applications like doors and windows curtain walls, high-speed trains, lightweight automotive components, and electronic heat sinks, the requirements for the mechanical properties and dimensional accuracy of aluminum profiles are gradually increasing. After aluminum alloy extrusion molding, a rapid cooling and quenching process is needed to ensure the material achieves the required microstructure and mechanical properties. In recent years, the aluminum profile industry has developed rapidly, and customers have increasingly diversified requirements for the hardness and strength of different alloys, which has placed new demands on in-line quenching equipment.

[0003] Existing aluminum profile quenching processes mainly employ a single mode, including air cooling, spray cooling, or water quenching. Air cooling relies on upper and lower fans to create airflow convection cooling, suitable for profiles requiring slower cooling rates. Spray cooling uses nozzles to spray water mist onto the profile surface, utilizing evaporation and heat absorption for faster cooling. Water quenching involves directly immersing the profile in water for rapid cooling to obtain high-hardness materials. Most of these devices are single-structure, and a single device typically only implements one cooling method. While some devices combine air cooling and spray cooling, their overall flexibility and adaptability remain limited.

[0004] However, the existing technologies have the following problems: First, different alloys and performance requirements necessitate multiple cooling methods, but single-mode equipment cannot be flexibly switched on the same production line, often requiring companies to configure multiple sets of equipment, increasing investment and floor space costs; second, the cooling rate is difficult to effectively adjust according to the profile cross-section and process requirements, easily leading to uneven cooling or rate deviations, resulting in unstable product hardness and performance; third, process mode switching usually requires manual operation or even equipment replacement, which is time-consuming and inefficient. In summary, existing quenching equipment can no longer meet the comprehensive needs of the rapidly developing aluminum profile industry for multi-mode quenching, process flexibility, efficiency, and cost control.

[0027] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Example 1

[0029] like Figures 1-3 As shown, a multi-mode aluminum profile quenching device is disclosed. It includes a housing 5 with baffles 7 at both ends. A conveyor belt 6 runs along a groove 4 inside the housing 5. The housing 5 houses a quenching device, which includes an air-cooling device 1, a spray device 1, and a water-cooling device 3. The housing 5 can activate different devices to perform quenching in different modes. Specific modes include air-cooling mode, mist-cooling mode, simultaneous air-cooling and mist-cooling mode, and water-cooling mode.

[0030] Reference Figure 1The housing 5 is a rectangular shell made of metal, with an opening at the top. Both ends of the housing 5 have removable baffles 7. The interior of the housing 5 has grooves 4, within which the quenching device can be installed. A conveyor belt 6 is installed within the grooves 4. In this embodiment, the conveyor belt 6 is a fixed plate with circular rollers mounted on it. The baffles 7 are located on both sides of the short side of the housing 5 and are fixed to the short side of the housing 5 in a liftable manner.

[0031] An upper air duct 11 for the air-cooling device 1 is provided at the top of the housing 5, and one of the pipes 21 of the spray device 2 is provided at the bottom of the upper air duct 11.

[0032] Reference Figure 1-3 The quenching device includes a spray device 2, an air-cooling device 1, and a water-cooling device 3. In the air-cooling device 1, multiple trapezoidal protrusions are arranged along the length of the conveyor belt on the inner bottom side of the housing 1 for upward airflow. A sealing device 32 can be installed on the top of the lower air duct 12 to prevent water from spraying out during water-cooling mode.

[0033] The upper air duct 11 is a rectangular pipe located on the outer side of the top of the housing. The lower end has an air outlet facing the conveyor belt; the outlet is a long, narrow slit with multiple outlets. A pipe 21 connected to a water source is located at the bottom of the upper air duct 11. In air-cooling mode, pipe 21 does not completely block the airflow from the upper air duct 11.

[0034] The air-cooling unit 1 uses an air source to supply air, which includes a fan unit and a frequency converter. The fan is connected to the upper air duct 11 and the lower air duct 12 via flanges. During operation in air-cooling mode, the air source provides upper and lower convective airflow, forming forced convection heat transfer on the profile surface. The upper and lower air speeds and can be independently adjusted and turned on / off. The upper air duct can be connected to a spray system to achieve mist cooling mixing. A drainage groove and a sealing ring are installed on the outside of the upper air duct 11 to prevent spray from entering the fan.

[0035] The spray device 2 comprises pipes 21, spray heads 22, and a water source. Pipes 21 consist of multiple water pipes, made of stainless steel or plastic-coated steel; in this embodiment, stainless steel pipes are used. Pipes 21 are arranged along the length of the housing 5, with four pipes 21 positioned at the four inner corners of the housing 5: near the side walls and the bottom corner; one pipe 21 is located on the outer top of the housing 5. In this embodiment, the pipe 21 located on the top of the housing 5 is fixed to the bottom of the upper air duct 11.

[0036] Multiple spray heads 22 are installed on the outer surface of the pipe 21, arranged at certain intervals to form a cross-spray. The spray heads 22 are adjustable atomizing nozzles, which can adjust the atomized particle size and mist volume. The spray heads 22 are carefully oriented towards the cross-section of the profile to be covered, forming a uniform water mist surround.

[0037] Pipe 21 is connected to a water source, which provides water to pipe 21 for spraying. Through the cooperation of pipe 21, spray head 22, and water source, fine water mist can be generated in mist cooling mode to achieve surface convection and evaporative cooling.

[0038] Pipe 21 is connected to the water source via a quick-connect fitting, and spray head 22 can be disassembled. Pipe 21 can also be disassembled during maintenance.

[0039] Reference Figure 3 ,

[0040] A water valve 31 is provided, which mainly supplies water to the groove 4 inside the housing 1. In this embodiment, the water valve 31 is a common valve connected to a water source. The water valve 31 is arranged inside the housing to directly introduce water into the groove 4 of the housing 5.

[0041] The sealing device 32 uses a stainless steel cover. A sealing strip is installed at the bottom. The sealing device 32 can close the opening between the top of the downdraft duct 1 and the housing 5 in water-permeable mode 3, preventing water from draining from the downdraft duct 12 or the top of the housing 5. When the water level introduced by the water valve 31 reaches a set standard, it can be manually closed.

[0042] In the water penetration mode, the sealing device 32 is placed on the top of the downdraft duct 12. The sealing device 32 has a shell-like structure and its overall appearance is similar to that of the downdraft duct 12. The sealing device 32 can be fitted onto the outside of the downdraft duct 12 to prevent water from escaping from the downdraft duct 12 during the water penetration mode.

[0043] During the water immersion mode, the sealing device 32 is closed, and water is rapidly injected into the groove 4 through the water valve 31 to the set water level, so that the aluminum profile is partially or completely immersed in the water. The water level is controlled by the baffle 7. The water immersion, in conjunction with the conveyor belt, can ensure the stable passage of the conveyor belt and the profile. During the water immersion mode, the sealing air-cooling device 1 and the spray device 2 are closed.

[0044] A pipe 21 connected to a water source is installed at the bottom of the upper air duct 11. When operating in the simultaneous air-cooling and mist-cooling mode, the air cooling can simultaneously provide fine mist to the pipe 21 at the bottom of the upper air duct, so that the air outlet carries mist, thereby improving heat exchange and surface cooling efficiency.

[0045] In this embodiment, the control device can operate in air-cooling mode, mist-cooling mode, and simultaneous air-cooling and mist-cooling mode by controlling the connection of the air source and water source. When the air source and water source are closed and connected, the water-passing mode can be performed. Baffles 7 are set at both ends of the groove 4, and the water valve 31 is activated to set the water required for the water-passing mode inside the groove 4.

[0046] In this embodiment, the upper air duct 11 is a rectangular pipe with an air outlet that is wide at the top and narrow at the bottom. The air outlet of the upper air duct 11 faces downward, and the center of the air outlet is on the same plane as the center of the conveyor belt 6.

[0047] The lower air duct 12 is located at the bottom of the housing 5. An air outlet that is wider at the bottom and narrower at the top is located at the bottom of the housing 5, and the opening of the air outlet of the lower air duct 12 faces upward. The air outlet of the lower air duct 12 passes through the housing 5, and air can be discharged from the air outlet into the groove 4 of the housing 5.

[0048] Pipe 22 is a round pipe for wiping, with an external thread or clamp nozzle interface. Spray head 22 is an adjustable atomizing nozzle, with a short conical or spherical nozzle body.

[0049] The sealing device 32 is slightly larger than the air outlet of the downdraft 12, and can fit over the air outlet of the downdraft 12 to prevent total water from entering the downdraft 12 from the air outlet of the downdraft 12 in the water-permeable mode.

[0050] In this embodiment, the water valve 31 is a manual switch. In another embodiment, the water valve 31 is a solenoid valve or an electric actuator valve that can be automatically closed.

[0051] In this embodiment, multiple conveyor belts 6 are provided. After entering the box 5, the aluminum profile can be slidably placed on the conveyor belt 6. The entire conveyor belt 6 is made of metal.

[0052] Two baffles 7 are provided on both sides of the short side of the box body 5. In this embodiment, the baffles 7 are made of wood. The baffles 7 are fixed to the short side of the box body 5 by grooves. The baffles 7 can slide in the vertical direction, and the baffles 7 can be set or removed at the short side of the box body 5.

[0053] In this embodiment, when the air-cooling mode is in operation, the upper air duct 11 and the lower air duct 12 can form a convection air duct, which can uniformly cool the aluminum profile. When the aluminum profile needs to be cooled at a slower rate or in an alloy state to prevent thermal cracking, it can be cooled by the air-cooling mode.

[0054] In mist cooling mode, the spray nozzles 22 can create a fine mist around the aluminum profiles on the conveyor belt 6, which can improve the surface heat transfer coefficient and remove heat through evaporation, making it suitable for medium cooling rate requirements. By setting the spray nozzles 22 in multiple directions on the conveyor belt 6, uniform cooling of the profiles can be ensured at different locations.

[0055] In the simultaneous operation mode of air cooling and mist cooling, the upper air duct 11 can emit airflow with mist to achieve rapid surface cooling and carry away mist droplets and steam through the airflow, taking into account both cooling speed and uniformity.

[0056] In the water-cooling mode, the profile is placed underwater to achieve rapid cooling and obtain a higher hardening effect, which is suitable for alloys with high hardness requirements or special processes.

[0057] In this embodiment, the upper air duct 11 and the lower air duct 12 are located above and below the conveyor belt 6, respectively; the pipes 21 are distributed at the four corners and the outer top of the conveyor belt 6, and uniform mist cooling is achieved through the evenly arranged spray nozzles 22. In the water-passing mode, the sealing device 32 can be fitted onto the top of the lower air duct 12 to achieve sealing.

[0058] Reference Figure 4 , Figure 4 In another embodiment of the present invention, a lower air duct 12 is provided at the bottom of the housing 5, and a fan 13 is provided at one end of the lower air duct 12. The fan 13 can blow air into the lower air duct 12. The top of the lower air duct 12 is provided at the bottom of the housing 5, and multiple air outlets are provided at the top of the lower air duct 12. The air outlets are located inside the housing 5 and are spaced apart by a certain distance.

[0059] A water tank 8 is provided on the side of the housing 5. A connecting hole is provided on the side of the housing 5 near the water tank 8. A partition can be opened or closed through the connecting hole. In the water-permeable mode, the connecting hole is open, allowing water inside the housing 5 to flow into the water tank 8 for circulation. In the non-water-permeable mode, the partition allows water or airflow to flow inside the housing 5 without entering the water tank 8.

[0060] In this embodiment, during the water quenching mode, the temperature of the aluminum material is relatively high, and the heat of the aluminum material diffuses into the water during the water quenching mode, causing the water temperature to gradually rise and affecting the quenching effect. By setting a water tank 8 on the side of the box 5, the water in the water tank 8 can flow with the inside of the box 5, replacing the water in the box 5 into the water tank 8.

[0061] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model.
