Description

Technical Field

[0001] This invention relates to the field of heat treatment furnace technology for aluminum alloy wheels, specifically to an adjustable temperature uniformity device for heat treatment furnaces of aluminum alloy wheels. Background Technology

[0002] Aluminum alloy wheels are widely used in the automotive industry due to their advantages such as light weight, high strength, and good heat dissipation. Heat treatment is a crucial process in the production of aluminum alloy wheels, significantly improving the microstructure and properties of the aluminum alloy, thereby enhancing the quality and reliability of the wheel. During heat treatment, the uniformity of furnace temperature has a decisive impact on the quality of the aluminum alloy wheel. Uneven furnace temperature leads to inconsistent microstructural transformations in different parts of the wheel, resulting in variations in wheel performance, such as uneven hardness and strength. In severe cases, it can even cause defects such as cracks, reducing the wheel's safety and service life.

[0003] The fixed angle and position of the guide vanes cannot be dynamically adjusted according to the temperature requirements of different areas inside the furnace, resulting in a rigid hot air circulation path. Under the guidance of the fixed guide vanes, the airflow generated by the axial flow fan often forms a single and fixed flow trajectory, making it difficult to cover all corners inside the furnace. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable temperature uniformity device for heat treatment furnaces of aluminum alloy wheels, which solves the problem of uneven temperature inside the heat treatment furnace by setting a temperature uniformity component.

[0005] To address the problems of existing technologies, this invention provides an adjustable aluminum alloy wheel heat treatment furnace temperature uniformity device, comprising: a heat treatment furnace body for heat treating aluminum alloy wheels; a second hot air circulation assembly, having two sets respectively disposed on both sides of the exterior of the heat treatment furnace body for circulating hot air within the heat treatment furnace body, the second hot air circulation assembly including a sleeve fixed to the back of the heat treatment furnace body; and a temperature equalization assembly, having two sets respectively disposed at the top and bottom of the heat treatment furnace body for rapidly delivering hot air into the interior of the heat treatment furnace body; the temperature equalization assembly includes an air outlet capable of reciprocating from the back of the heat treatment furnace body to the front of the heat treatment furnace body, and the second hot air circulation assembly capable of delivering hot air from the heat treatment furnace body to the air outlet.

[0006] Preferably, the temperature equalization component includes a multi-stage guide pipe installed on the air outlet, and one end of the multi-stage guide pipe extends into the sleeve. When the air outlet moves back and forth from the back of the heat treatment furnace body to the front of the heat treatment furnace body, the multi-stage guide pipe can be extended or shortened.

[0007] Preferably, the temperature equalization assembly further includes a second sprocket disposed at the front and back of the heat treatment furnace body and connected to the second sprocket by a shaft, the second sprocket being engaged with a second chain, and the temperature equalization assembly further includes a second rotary drive component disposed outside the heat treatment furnace body and used to drive the second sprocket to rotate.

[0008] Preferably, the second hot air circulation assembly includes a second fan disposed outside the heat treatment furnace body and used to draw hot air out of the heat treatment furnace body. The air inlet end of the second fan is connected to a third connecting pipe, which is connected to the heat treatment furnace body. The air outlet end of the second fan is connected to a fourth connecting pipe. One end of the fourth connecting pipe is connected to a diverter pipe, and both ends of the diverter pipe are connected to upper and lower sleeves.

[0009] Preferably, heating devices for heating the air inside the heat treatment furnace body are also provided on both sides of the inner wall of the heat treatment furnace body. The heating device includes a fixing frame fixed to the inner wall of the heat treatment furnace body, and a heater for heating is provided inside the fixing frame.

[0010] Preferably, the heating device further includes several guide vanes that are rotatably set at the air outlet of the fixed frame. When heating, each guide vane rotates to discharge hot air from the fixed frame.

[0011] Preferably, a first sprocket is fixed on the shaft of each guide plate, and a first chain is meshed on the first sprocket. A first gear is also provided on one of the guide plates. The heating device further includes a first rotary drive component disposed on the heat treatment furnace body. The output end of the first rotary drive component is connected to a second gear, and the second gear meshes with the first gear.

[0012] Preferably, the heat treatment furnace body further includes two sets of first hot air circulation components arranged on both sides of the heat treatment furnace body and conveying air from the heat treatment furnace body to the heating device.

[0013] Preferably, the first hot air circulation assembly includes a first fan disposed outside the heat treatment furnace body, the air outlet of the first fan is connected to a first connecting pipe, one end of the first connecting pipe is connected to the heat treatment furnace body, the air outlet of the first fan is connected to a second connecting pipe, and one end of the second connecting pipe extends to the fixed frame.

[0014] Preferably, the feed end of the heat treatment furnace body is also provided with a sealing door.

[0015] The advantages of this invention compared to the prior art are: The heat treatment furnace body involved in this application features a three-dimensional temperature control system formed by the layout of temperature equalization components at both the top and bottom. The temperature equalization component, as the core temperature control unit, is keyly equipped with an air outlet that can reciprocate along the direction from the back to the front of the furnace body. This dynamic air outlet structure breaks through the limitations of the traditional fixed air outlet mode, providing a foundation for temperature uniformity in all areas of the furnace. Specifically, the second fan serves as the power source for hot air delivery in the system. It draws hot air from inside the heat treatment furnace body and continuously delivers it to the air outlet. Due to the reciprocating movement of the air outlet, when the hot air is discharged through the outlet, it can cover the entire area inside the heat treatment furnace body from the back to the front. By dynamically adjusting the air outlet position, the hot air can accurately reach any corner inside the furnace, effectively avoiding temperature deviations in local areas due to insufficient wind speed or excessive distance, and significantly improving the temperature uniformity inside the heat treatment furnace body. In the design of the hot air circulation system, this application achieves efficient airflow guidance and adjustment through a combination structure of a fixed frame and a guide plate. The fixed frame serves as the mounting carrier for the baffles, on which several adjustable-angle baffles are evenly distributed. By changing the angle between the baffles and the horizontal plane, the direction of the hot air outlet can be controlled, allowing the airflow to be delivered according to the temperature requirements of different areas within the furnace. Simultaneously, the first fan, as the power core of the circulation system, works in conjunction with the fixed frame to form a complete hot air circulation path. The negative pressure generated by the first fan rapidly draws hot air from the heat treatment furnace body into the fixed frame, where it is then redirected by the baffles and reintroduced into the furnace. This process not only achieves hot air circulation but also shortens the time required for the furnace temperature to reach equilibrium. In summary, the active temperature control system, composed of the second fan and the temperature equalization component, combined with the circulation regulation system consisting of the first fan, fixed frame, and baffles, forms a dual temperature control mechanism. The coordinated operation of these two systems ensures both high temperature uniformity within the heat treatment furnace body and rapid hot air circulation within the furnace, effectively improving heat treatment efficiency and quality. This is suitable for heat treatment processes requiring high temperature accuracy. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-8As shown, the present invention provides an adjustable aluminum alloy wheel heat treatment furnace temperature uniformity device, comprising: a heat treatment furnace body 1 for heat treating aluminum alloy wheels; a sealing door 11 is also provided at the feeding end of the heat treatment furnace body 1; a second hot air circulation assembly 3, having two sets respectively disposed on both sides outside the heat treatment furnace body 1 for circulating hot air in the heat treatment furnace body 1, the second hot air circulation assembly 3 including a sleeve 35 fixed to the back of the heat treatment furnace body 1; a temperature equalization assembly 5, having two sets respectively disposed at the top and bottom of the heat treatment furnace body 1 for rapidly delivering hot air to the interior of the heat treatment furnace body 1; the temperature equalization assembly 5 including an air outlet 51 capable of reciprocating from the back of the heat treatment furnace body 1 to the front of the heat treatment furnace body 1, the second hot air circulation assembly 3 capable of delivering hot air in the heat treatment furnace body 1 to the air outlet 51.

[0027] When heat-treating aluminum alloy wheels, the wheels are placed inside the heat treatment furnace body 1, and the sealing door 11 is closed to create a relatively sealed heat treatment environment. The heat treatment furnace body 1 begins operation, heating the interior. Simultaneously, two sets of second hot air circulation components 3 activate, circulating the hot air within the furnace body 1. During circulation, the hot air exchanges heat with the inner wall of the furnace body 1, the aluminum alloy wheels, and other components, resulting in a more uniform temperature within the furnace. Two sets of temperature equalization components 5 also begin operation, with the second hot air circulation components 3 delivering the hot air from the furnace body 1 to the outlet 51 of the temperature equalization components 5. As the outlet 51 moves back and forth from the back of the furnace body 1 to the front, it rapidly and evenly blows the hot air into all areas of the furnace body 1. In this way, by combining the circulation of the second hot air circulation component 3 with the rapid and uniform air supply of the temperature equalization component 5, the temperature field inside the heat treatment furnace body 1 is continuously adjusted and optimized, so that all parts of the aluminum alloy wheel can be in a uniform temperature environment during the heat treatment process, thereby achieving high-quality heat treatment and ensuring the uniformity and stability of the aluminum alloy wheel's performance.

[0028] The temperature equalization component 5 includes a multi-stage guide pipe 511 installed on the air outlet 51, and one end of the multi-stage guide pipe 511 extends into the sleeve 35. When the air outlet 51 moves from the back of the heat treatment furnace body 1 to the front of the heat treatment furnace body 1 and moves back and forth, the multi-stage guide pipe 511 can extend or shorten. This telescopic design allows the guide pipe to adapt to the movement of the air outlet 51, ensuring that hot air can still be stably delivered from the second hot air circulation component 3 to the air outlet 51 through the guide pipe during the movement of the air outlet 51. There will be no interruption or instability in the hot air delivery due to the movement of the air outlet 51, thereby ensuring that the temperature equalization component 5 can continuously and effectively play its temperature equalization role.

[0029] The temperature equalization assembly 5 also includes a second sprocket 52 disposed at the front and back of the heat treatment furnace body 1 and connected to the second sprocket 52 by a shaft. A second chain 521 is engaged on the second sprocket 52. The temperature equalization assembly 5 also includes a second rotary drive member 53 disposed outside the heat treatment furnace body 1 and used to drive the second sprocket 52 to rotate.

[0030] The second rotary drive 53 is activated, generating rotational power and transmitting it to the connected second sprocket 52. When the second sprocket 52 rotates, it drives the meshing second chain 521. Since the second sprocket 52 is respectively located at the front and back of the heat treatment furnace body 1 via shafts, the second chain 521 pulls the air outlet 51 to reciprocate between the back and front of the heat treatment furnace body 1 during transmission.

[0031] The second hot air circulation assembly 3 includes a second fan 31 disposed outside the heat treatment furnace body 1 and used to draw out hot air from the heat treatment furnace body 1. The air inlet end of the second fan 31 is connected to a third connecting pipe 32, which is connected to the heat treatment furnace body 1. The air outlet end of the second fan 31 is connected to a fourth connecting pipe 33. One end of the fourth connecting pipe 33 is connected to a diversion pipe 34, and both ends of the diversion pipe 34 are connected to upper and lower sleeves 35.

[0032] The second hot air circulation component 3 starts working, and the second fan 31 rotates at high speed, generating a strong suction at the air inlet. Hot air inside the heat treatment furnace body 1 is drawn into the second fan 31 through the third connecting pipe 32. After gaining pressure in the second fan 31, the hot air is blown out from the air outlet through the fourth connecting pipe 33. The fourth connecting pipe 33 delivers the hot air to the distribution pipe 34, which evenly distributes the hot air into the upper and lower sleeves 35. The sleeves 35 further deliver the hot air to the air outlet 51 of the temperature equalization component 5.

[0033] Heating devices 4 for heating the air inside the heat treatment furnace body 1 are also provided on both sides of the inner wall of the heat treatment furnace body 1. The heating device 4 includes a fixing frame 42 fixed to the inner wall of the heat treatment furnace body 1. A heater 41 for heating is also provided inside the fixing frame 42. The heater 41 is the core heating component of the heating device 4. It generates a large amount of heat through the conversion of electrical energy. This heat is directly released into the air inside the heat treatment furnace body 1, raising the air temperature and thus providing the necessary heat source for the heat treatment of aluminum alloy wheels.

[0034] The heating device 4 also includes several rotatable guide vanes 44 at the air outlet of the fixed frame 42. When heating, each guide vane 44 rotates to discharge hot air from the fixed frame 42. By changing its rotation angle, the flow direction of the hot air discharged from the fixed frame 42 can be adjusted.

[0035] Each guide vane 44 has a first sprocket 441 fixed on its shaft, and a first chain 45 meshes with the first sprocket 441. When one guide vane 44 rotates, the first chain 45 drives the other first sprockets 441 to rotate synchronously, thus enabling all guide vanes 44 to rotate at the same angle and direction. This linkage mechanism ensures the consistency of the movement of each guide vane 44, and can simultaneously adjust the flow direction of hot air in a unified manner. The chain drive has the characteristics of smooth and reliable transmission and can withstand large loads. One of the guide vanes 44 is also provided with a first gear 442. The heating device 4 also includes a first rotary drive component 43 provided on the heat treatment furnace body 1. The first rotary drive component 43 is the power source of the entire guide vane 44 rotation system. It can be a motor, reducer, or other device that can provide rotational power. The output end of the first rotary drive component 43 is connected to a second gear 431, and the second gear 431 meshes with the first gear 442.

[0036] The output end of the first rotary drive 43 drives the second gear 431 to rotate. Since the second gear 431 meshes with the first gear 442 on one of the guide plates 44, the rotational motion of the second gear 431 is transmitted to the first gear 442, causing the guide plate 44 to start rotating. Because each guide plate 44 has a first sprocket 441 fixed on its shaft, and these first sprockets 441 are interconnected by a first chain 45, when one guide plate 44 rotates, the other first sprockets 441 are driven to rotate synchronously through the first chain 45, thereby causing all guide plates 44 to rotate at the same angle and direction.

[0037] The heat treatment furnace body 1 also includes two sets of first hot air circulation components 2, which are arranged on both sides of the heat treatment furnace body 1 and transport the air in the heat treatment furnace body 1 to the heating device 4. During the heat treatment process, the heating device 4 generates a large amount of heat to heat the air inside the furnace. The first hot air circulation components 2 extract the air from both sides of the heat treatment furnace body 1, reheat it through the heating device 4, and then send it back into the furnace, forming a circulation of hot air. The first hot air circulation components 2 include a first fan 21 arranged outside the heat treatment furnace body 1. The air outlet of the first fan 21 is connected to a first connecting pipe 211. One end of the first connecting pipe 211 is connected to the heat treatment furnace body 1. The air outlet of the first fan 21 is connected to a second connecting pipe 212. One end of the second connecting pipe 212 extends into the fixed frame 42.

[0038] The first hot air circulation assembly 2 starts working. The first fan 21 begins to rotate at high speed, generating a strong suction at the air inlet. Under the action of suction, air from both sides of the heat treatment furnace body 1 is drawn into the first fan 21 through the first connecting pipe 211. After gaining a certain pressure in the first fan 21, this air is transported from the air outlet to the fixed frame 42 of the heating device 4 through the second connecting pipe 212. The temperature rises further. At this time, the first rotary drive 43 starts working according to the preset heat treatment program or the instructions issued by the temperature control system. The output end of the first rotary drive 43 drives the second gear 431 to rotate. Since the second gear 431 meshes with the first gear 442 on one of the guide plates 44, the rotational motion of the second gear 431 is transmitted to the first gear 442, causing the guide plate 44 to start rotating. Because each guide vane 44 has a first sprocket 441 fixed on its shaft, and these first sprockets 441 are interconnected by a first chain 45, when one guide vane 44 rotates, the other first sprockets 441 rotate synchronously via the first chain 45, thereby causing all guide vanes 44 to rotate at the same angle and direction. The guide vanes 44 blow the hot air, which has been reheated by the heater 41, into the heat treatment furnace body 1 at a specific angle and direction, causing the hot air to circulate within the furnace.

[0039] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
