Description

Technical Field

[0001] This utility model relates to the field of aluminum profile heat treatment technology, and in particular to an aluminum profile heat treatment device. Background Technology

[0002] Heat treatment technology for aluminum profiles is a crucial process for improving their performance, primarily including solution treatment and aging treatment. Artificial aging treatment involves heating the solution-treated aluminum profile to a specific temperature to accelerate the diffusion of solute atoms and the precipitation of strengthening phases. The temperature for artificial aging is typically between 150 and 200°C, and the time ranges from several hours to tens of hours. Depending on the composition of the aluminum alloy and product requirements, different combinations of aging temperatures and times can be selected to achieve optimal performance.

[0003] In the prior art, such as the patent disclosed in announcement number CN219385216U, an aluminum profile heat treatment device is disclosed, including a box body, a heating chamber is arranged inside the box body, an electric heating tube is arranged inside the heating chamber, a motor box is arranged on one side of the box body, a motor is arranged inside the motor box, and a rotating shaft is arranged at one end of the motor.

[0004] The above solution has the following problems: 1. The heating chamber is located at the bottom of the box, which causes the aluminum profile on the rod (i.e., the one placed on the rod) to be heated unevenly on its outer and inner sides relative to the rotating shaft during the rotation process, thus affecting the heat treatment effect.

[0005] 2. The through rod, rotating shaft and fixed plate cannot be removed as a whole, which makes the loading and unloading of aluminum alloy on the through rod cumbersome and inefficient, affecting production efficiency. Utility Model Content

[0006] To address the problem that uneven heating of the outer and inner surfaces of aluminum profiles during rotational heating, which affects the heat treatment effect, this utility model provides a heat treatment device for aluminum profiles.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: A heat treatment apparatus for aluminum profiles includes a chamber with several electric heating tubes installed on its inner wall. A placement rack is rotatably mounted inside the chamber. The placement rack includes a rotating shaft with a fixed plate fixedly mounted on it. Placement rods are evenly arranged along the circumference of the fixed plate. The rotating shaft is hollow and has several through holes. A hot air circulation mechanism is installed on the chamber and connected to the rotating shaft. This heat treatment apparatus provides a stable heat source by installing several electric heating tubes on the inner wall of the chamber. The rotating rack inside the chamber, with its rotating shaft and fixed plate, facilitates the placement of aluminum profiles. The hollow rotating shaft with several through holes connects to the hot air circulation mechanism on the chamber, allowing hot air to be evenly discharged from the center of the placement rack, resulting in more uniform heating of the aluminum profiles and improved heat treatment effect.

[0008] Preferably, the left end of the rotating shaft is closed, and the right end is open; a first through hole is provided on the right side wall of the housing to match the open end of the rotating shaft; the hot air circulation mechanism includes a circulating fan installed on the outside of the right side wall of the housing; the air outlet pipe of the circulating fan is located in the first through hole; the air inlet pipe of the circulating fan is connected to the exhaust port opened on the top surface of the housing. This allows the circulating fan to accurately guide the hot air discharged from the top of the housing into the interior of the rotating shaft, and blow it out evenly through the through hole on the rotating shaft, effectively promoting the circulation of hot air inside the housing, further ensuring that the aluminum profile is heated evenly during the heat treatment process, improving the overall heat treatment quality, and at the same time, a reasonable ventilation layout helps to improve energy utilization efficiency and optimize equipment operating performance.

[0009] Preferably, a flared opening is provided at the connection between the air inlet duct and the air outlet. The flared opening increases the contact area between the air inlet duct and the air outlet, allowing hot air exhausted from the exhaust outlet on the top of the enclosure to enter the air inlet duct more smoothly and efficiently, reducing resistance and turbulence at the connection point. This not only improves the efficiency of hot air collection, ensuring more hot air can participate in the circulation in a timely manner, but also further enhances the smoothness of hot air circulation within the enclosure.

[0010] Preferably, the rotating shaft is rotatably mounted on the base; a guide rail is fixedly mounted on the bottom surface of the housing; the base is slidably mounted on the guide rail; a limit block is provided on the guide rail; and a door is provided on the front side of the housing. The guide rail fixed on the bottom surface of the housing and the base slidably mounted on it make the movement of the placement rack more convenient, facilitating the loading and unloading of aluminum profiles on the placement rack and improving operational efficiency; the limit block on the guide rail effectively limits the range of movement of the base, ensuring the normal operation of the device; the door on the front side of the housing facilitates the overall movement of the placement rack and the assembly and disassembly of aluminum profiles on the placement rack.

[0011] Preferably, a mounting base is fixedly installed on the outer side of the left side wall of the housing; a motor is mounted on the mounting base; the motor is connected to a rotating shaft via a connecting mechanism; a second through hole is opened on the left side wall of the housing to mate with the left end of the rotating shaft; the left and right ends of the rotating shaft are clearance-fitted with the inner wall of the housing. The connecting mechanism facilitates quick connection and disconnection between the motor and the rotating shaft.

[0012] Preferably, the connecting mechanism includes a translation component and a plug-in component; the translation component includes a sliding plate; a motor is fixedly mounted on the sliding plate; the sliding plate is slidably mounted on a mounting base; a lead screw is rotatably mounted on the sliding plate; the lead screw is threadedly connected to the mounting base; the motor output end is connected to the plug-in component; a first blind hole is opened at the left end of the rotating shaft; the plug-in component can be inserted into the first blind hole. The motor is fixed to the sliding plate of the translation component and slides on the mounting base. The lead screw rotatably mounted on the sliding plate is threadedly connected to the mounting base. By rotating the lead screw, the position of the sliding plate can be adjusted, thereby adjusting the position of the motor; the plug-in component connected to the motor output end can quickly plug into and separate from the first blind hole at the left end of the rotating shaft. This design not only facilitates the motor driving the rotating shaft to rotate the placement rack, achieving uniform heating of the aluminum profile, but also allows the motor to separate from the rotating shaft in time when the entire placement rack is removed, improving the efficiency of the removal operation.

[0013] Preferably, the plug-in assembly includes a connecting shaft fixedly connected to the motor output end; a second blind hole is provided on the right side of the connecting shaft; a spring is fixedly installed on the bottom surface of the second blind hole; a plug-in block is fixedly connected to the end of the spring away from the bottom surface of the second blind hole; the plug-in block is configured to cooperate with the first blind hole. Utilizing the elasticity of the spring, when the motor and shaft are connected, the plug-in block can be aligned with the first blind hole and inserted under the action of the spring, ensuring stable power transmission and enabling the motor to efficiently drive the shaft to rotate the placement rack, achieving uniform heating of the aluminum profile; when it is necessary to remove the entire placement rack or to repair or replace the motor and shaft, the translation assembly moves the motor and plug-in assembly away from the shaft, allowing the plug-in block to be pulled out of the first blind hole, separating the motor from the shaft in a timely manner. This improves the efficiency of removing the placement rack, significantly reduces equipment maintenance difficulty and time costs, ensures the smooth progress of aluminum profile heat treatment, and improves the flexibility and reliability of the equipment.

[0014] Preferably, a limiting disc is provided on the connecting shaft. The limiting disc can precisely limit the axial movement range of the connecting shaft, ensuring the connection between the plug block and the first blind hole. When maintenance requires separating the motor and the shaft, the limiting disc also serves as a prompt. By observing the position of the limiting disc, operators can quickly determine whether the connecting shaft is in the appropriate separation state, further improving operational convenience and safety, and facilitating the efficient and stable operation of aluminum profile heat treatment.

[0015] As can be seen from the above technical solutions, the advantages of this utility model include: 1. The rotating shaft is hollow and has several through holes, which are connected to the hot air circulation mechanism on the box, so that hot air can be evenly discharged from the middle of the placement rack, making the aluminum profile more evenly heated and improving the heat treatment effect.

[0016] 2. The reasonable design of the connecting mechanism not only facilitates the motor to drive the rotating shaft to rotate the placement rack and achieve uniform heating of the aluminum profile, but also ensures that the motor separates from the rotating shaft in time when the whole structure is removed from the placement rack, thus improving the efficiency of the removal operation.

Detailed Implementation

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] like Figure 1 and Figure 4As shown, an aluminum profile heat treatment device includes a housing 1, with a plurality of electric heating tubes 2 arranged on the inner wall of the housing 1; a placement rack 3 is rotatably arranged inside the housing 1; the placement rack 3 includes a rotating shaft 301; a fixing plate 302 is fixedly arranged on the rotating shaft 301; placement rods 303 are evenly arranged along the circumferential direction on the fixing plate 302; the rotating shaft 301 is hollow and has a plurality of through holes; a hot air circulation mechanism is arranged on the housing 1; the hot air circulation mechanism is connected to the rotating shaft 301.

[0022] The aluminum profile heat treatment device provides a stable heat source by setting several electric heating tubes 2 on the inner wall of the chamber 1. The placement rack 3, which is rotatably set inside the chamber 1, includes a rotating shaft 301 with a fixing plate 302 and a placement rod 303, which facilitates the placement of aluminum profiles. The rotating shaft 301 is hollow and has several through holes, and is connected to the hot air circulation mechanism on the chamber 1, so that hot air can be evenly discharged from the middle of the placement rack 3, making the aluminum profile more evenly heated and improving the heat treatment effect.

[0023] like Figure 2 As shown, the left end of the rotating shaft 301 is closed, and the right end is open; a first through hole 101 is provided on the right side wall of the housing 1 to match the open end of the rotating shaft 301; the hot air circulation mechanism includes a circulating fan 4 installed on the outside of the right side wall of the housing 1; the air outlet pipe 401 of the circulating fan 4 is located in the first through hole 101; the air inlet pipe 402 of the circulating fan 4 is connected to the exhaust port 102 opened on the top surface of the housing 1. A flared mouth 403 is provided at the connection between the air inlet pipe 402 and the exhaust port 102.

[0024] Electric heating element 2 heats the air inside the chamber. As the temperature rises, the hot air at the top of the chamber is exhausted through exhaust vent 102. At this time, circulating fan 4 starts, and its inlet pipe 402 collects the hot air exhausted from exhaust vent 102 through flared opening 403. Because flared opening 403 increases the contact area, the hot air can enter the inlet pipe 402 more smoothly. Subsequently, the hot air is pressurized by circulating fan 4 and guided into the rotating shaft 301 through outlet pipe 401, and then blown out evenly from several through holes on the rotating shaft 301, thereby heating the aluminum profile placed on the rack 3. Through this hot air circulation design, the hot air inside chamber 1 can form a good circulation path, allowing the aluminum profile to be heated more evenly during the heat treatment process, thereby improving the overall heat treatment quality. Secondly, the reasonable ventilation layout makes full use of the hot air, improves energy efficiency, and optimizes equipment operation performance. Furthermore, the design of the flared opening 403 reduces the resistance and turbulence of hot air at the connection point, improves the collection efficiency of hot air, further ensures the smooth circulation of hot air within the housing 1, and guarantees the efficient operation of the aluminum profile heat treatment process.

[0025] In order to move the entire shelf 3 out, such as Figure 2 and Figure 3As shown, the rotating shaft 301 is rotatably mounted on the base 11; a guide rail 103 is fixedly mounted on the bottom surface of the box 1; the base 11 is slidably mounted on the guide rail 103; a limit block 105 is provided on the guide rail 103; a box door 106 is provided on the front side of the box 1. A mounting base 107 is fixedly mounted on the outer side of the left side wall of the box 1; a motor 5 is mounted on the mounting base 107; the motor 5 is connected to the rotating shaft 301 through a connecting mechanism; a second through hole 104 is provided on the left side wall of the box 1 to match the left end of the rotating shaft 301; the left and right ends of the rotating shaft 301 are clearance-fitted with the inner wall of the box 1. This facilitates the movement of the placement rack 3 and the loading and unloading of aluminum profiles: the guide rail 103 fixed on the bottom surface of the box 1 and the base 11 slidably mounted on it allow the placement rack 3 to be moved easily, facilitating the loading and unloading of aluminum profiles on the placement rack 3 and improving operational efficiency. The limiting block 105 on the guide rail 103 effectively limits the movement range of the base 11, preventing the base 11 from exceeding its reasonable position during movement, thus ensuring the normal operation of the device. The door 106 on the front side of the housing 1 provides convenient conditions for the overall movement of the placement rack 3, further facilitating the disassembly and assembly of the aluminum profiles on the placement rack 3. By fixing the mounting base 107 on the outer side of the left side wall of the housing 1 and installing the motor 5 on it, the motor 5 is connected to the rotating shaft 301 through a connecting mechanism, and the left and right ends of the rotating shaft 301 are clearance-fitted with the inner wall of the housing 1. This design facilitates the quick connection and separation of the motor 5 and the rotating shaft 301.

[0026] In the above configuration, the connecting mechanism includes a translation component and a plug-in component. The translation component includes a sliding plate 6; a motor 5 is fixedly mounted on the sliding plate 6; the sliding plate 6 is slidably mounted on the mounting base 107; a lead screw 7 is rotatably mounted on the sliding plate 6; the lead screw 7 is threadedly connected to the mounting base 107; the output end of the motor 5 is connected to the plug-in component; a first blind hole 304 is provided at the left end of the rotating shaft 301; the plug-in component can be inserted into the first blind hole 304. The plug-in component includes a connecting shaft 8 fixedly connected to the output end of the motor 5; a second blind hole 801 is provided on the right side of the connecting shaft 8; a spring 9 is fixedly mounted on the bottom surface of the second blind hole 801; a plug-in block 10 is fixedly connected to the end of the spring 9 away from the bottom surface of the second blind hole 801; the plug-in block 10 is configured to cooperate with the first blind hole 304. A limit plate 802 is provided on the connecting shaft 8. The plug-in block 10 is a polygonal prism or a triangular prism; in this embodiment, the plug-in block 10 is a quadrangular prism.

[0027] When the device needs to be started for heat treatment of aluminum profiles, the position of the slide plate 6 on the mounting base 107 is first adjusted by rotating the lead screw 7. Since the lead screw 7 is threadedly connected to the mounting base 107, rotating the lead screw 7 can push the slide plate 6 to slide, thereby driving the motor 5 fixed on the slide plate 6 to move. When the motor 5 moves to the point where the plug block 10 abuts against the rotating shaft 301, the plug assembly connected to the output end of the motor 5 starts to work.

[0028] Under the elastic action of the spring 9, the plug-in block 10 on the connecting shaft 8 is pressed against the left end of the rotating shaft 301. At this time, the connecting shaft 8 is manually rotated until the plug-in block 10 is inserted into the first blind hole 304 under the action of the spring 9. At this time, the motor 5 can establish a connection with the rotating shaft 301 through the connecting shaft 8 and the plug-in block 10, driving the rotating shaft 301 to drive the placement rack 3 to rotate, so as to achieve uniform heating of the aluminum profile. When it is necessary to remove the entire placement rack 3 for loading and unloading of aluminum profiles or for maintenance of the device, the lead screw 7 is rotated in the opposite direction, so that the slide plate 6 moves the motor 5 and the plug-in assembly away from the rotating shaft 301. The limiting plate 802 set on the connecting shaft 8 can accurately limit the axial movement range of the connecting shaft 8 during the connection between the motor 5 and the rotating shaft 301, ensuring that the plug-in block 10 is tightly connected to the first blind hole 304 and ensuring stable power transmission. When it is necessary to separate the motor 5 from the shaft 301, the limit plate 802 can serve as a prompt. By observing the position of the limit plate 802, the operator can quickly determine whether the connecting shaft 8 is in a suitable separation state.

[0029] The design of this connecting mechanism offers several advantages. First, the cooperation between the lead screw 7, slide plate 6, and mounting base 107 in the translation assembly allows for flexible adjustment of the motor 5's position, facilitating the connection and separation of the motor 5 from the rotating shaft 301 and improving operational convenience. Second, the spring 9 in the insertion assembly ensures that the insertion block 10 aligns with and inserts into the first blind hole 304, guaranteeing stable power transmission and ensuring uniform heating of the aluminum profile under motor drive. Third, the limiting plate 802 ensures stability during connection and provides a clear indication during separation, further enhancing operational convenience and safety, significantly improving equipment maintenance efficiency, and enhancing the efficiency and stability of aluminum profile heat treatment.
