[0002] Annealing is a metal heat treatment process that involves slowly heating the metal to a certain temperature, holding it for a sufficient time, and then cooling it at an appropriate rate. Broadly speaking, annealing is a heat treatment process for materials, including both metallic and non-metallic materials.

[0003] During the annealing process of aluminum alloy sheets, the annealing furnace currently used is specially treated to ensure a constant temperature during the heating process and reduce the amount of heat radiated outward during heating. This also results in a relatively slow cooling process after the annealing process, which affects overall production efficiency. Utility Model Content

[0040] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] Example:

[0042] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 This embodiment discloses an annealing furnace for aluminum alloy plates, including a furnace body 10, a clamping assembly 20, a sealing plate 30, a lifting assembly 40, a fan 50 and a heating assembly 60, wherein the furnace body 10 has a plurality of air outlets 11, each of which corresponds to a sealing plate 30, and the sealing plate 30 is arranged on the lifting assembly 40. The position of the sealing plate 30 and the air outlet 11 is driven by the lifting assembly 40, thereby realizing the opening and closing of the air outlet 11.

[0043] A material inlet is provided at one end of the furnace body 10, which is provided with an openable and closable door panel (not shown). A clamping assembly 20 is disposed within the furnace body 10 and is used to clamp the aluminum alloy sheet 70. An air inlet 12 is provided on one side of the furnace body 10, and a fan 50 is installed at the air outlet 11.

[0044] Specifically, the furnace body 10 has a hollow interior and a plurality of strip-shaped air outlets 11 at its top. Each air outlet 11 is positioned parallel to one another, and a corresponding sealing plate 30 is positioned above each air outlet 11, ensuring that all sealing plates 30 are also positioned parallel to one another. A lifting assembly 40 is connected to all sealing plates 30 and is used to simultaneously drive all sealing plates 30 to move within the furnace body 10.

[0045] The fan 50 covers the air inlet 12 , and the air flow passing through the fan 50 flows from outside the furnace body 10 into the furnace body 10 , and at the same time, the air flow entering the furnace body 10 is discharged from the furnace body 10 through the air outlet 11 .

[0046] The heating component 60 is arranged in the furnace body 10 and is used to heat the aluminum alloy plate 70. During the operation of the heating component 60, the fan 50 is in the off state, and all the sealing plates 30 cooperate with all the air outlets 11 to block all the air outlets 11.

[0047] In this embodiment, an air outlet 11 is provided on the top of the furnace body 10, and an air inlet 12 is provided on the side of the furnace body 10. In the entire annealing process, the aluminum alloy plate 70 is first installed on the clamping assembly 20, and the two ends of the aluminum alloy plate 70 are fixed by the two clamping forces in the clamping assembly, and then the aluminum alloy plate 70 is continuously heated by the heating assembly 60. During this process, the sealing plate 30 blocks the air outlet 11.

[0048] During the cooling process, the lifting assembly 40 drives all the sealing plates 30 to leave the air outlet 11, and at this time the fan 50 is started, and the cold air outside the furnace body 10 is sent into the furnace body 10 through the fan 50, and the hot air in the furnace body 10 is blown out from the air outlet 11.

[0049] In this technical solution, by designing an air outlet 11 that can be opened and closed, the temperature in the furnace body 10 can be quickly reduced, thereby achieving the purpose of improving the overall production efficiency.

[0050] In one specific embodiment:

[0051] In order to improve the sealing performance between the sealing plate 30 and the air outlet 11, the cross section of the air outlet 11 is T-shaped, and the cross section of the sealing plate 30 is also T-shaped. In order to facilitate the sealing plate 30 to be embedded in the air outlet 11, a chamfered structure is provided on the sealing plate 30.

[0052] In another specific embodiment:

[0053] The lifting assembly 40 includes a support plate 41, a screw 42, and a motor 43. Specifically, there are two support plates 41, each with a threaded hole at its end. The two support plates 41 are arranged parallel to each other inside the furnace body 10 and are connected to the bottom of the sealing plate 30 at both ends.

[0054] There are four screw rods 42, and the four screw rods 42 respectively match the four threaded holes on the two support plates 41. The screw rods 42 are vertically arranged in the furnace body 10. The top ends of the screw rods 42 pass through the top of the furnace body 10 and are rotatably connected to the furnace body 10. The bottom ends of the screw rods 42 are rotatably connected to a connecting plate fixed to the inner wall of the furnace body 10.

[0055] There are also four motors 43, all of which are arranged on the top of the outer surface of the furnace body 10, and the output shafts of the motors 43 are coaxially connected to the top of the screw 42. The four motors 43 move synchronously.

[0056] In this embodiment, four motors 43 drive four screws 42 to move synchronously, thereby driving the two support plates 41 to move upward or downward, and further driving the sealing plate 30 to move closer to or away from the air outlet 11.

[0057] In another specific embodiment:

[0058] The bottom surface of the sealing plate 30 is provided with a strip-shaped groove 31 , and the heating assembly 60 includes an electric heater, which is arranged in the strip-shaped groove 31 . This design allows for reasonable utilization of the internal space of the furnace body 10 .

[0059] In another specific embodiment:

[0060] The clamping assembly 20 includes two clamping plates 21, which are respectively arranged on both sides of the furnace body 10. The middle part of the clamping plate 21 is rotatably connected to the middle part of the furnace body 10. A U-shaped clamp 22 is respectively provided at both ends of the clamping plate 21, and a bolt is provided on the U-shaped clamp 22.

[0061] In this embodiment, when clamping the aluminum alloy plate 70, the four corners of the aluminum alloy plate 70 are fixed to the U-shaped clamp 22 by bolts. During the cooling process of the annealing process, the aluminum alloy plate 70 is driven to rotate by the rotatable clamping plate 21, thereby increasing the cooling speed of the aluminum alloy plate 70.

[0062] In another specific embodiment:

[0063] The air inlet 12 includes a plurality of strip-shaped through slots, each of which is provided with a cover plate 13 . A spring 14 is provided at each end of the cover plate 13 , and the spring 14 is connected to the side of the fan 50 .

[0064] The air inlet 12 on the furnace body 10 is a square window structure, a pressure plate is provided on the outer surface of the window structure, and a through groove is provided on the pressure plate; a cover plate 13 and a spring 14 are provided between the pressure plate and the fan 50.

[0065] The length and width of the pressing plate are both larger than the length and width of the through slot.

[0066] In this embodiment, when the furnace body 10 is in the heating process, the cover plate 13, under the action of the spring 14, covers the through-slots and blocks all through-slots, sealing the air inlet 12 and preventing heat from escaping from the furnace body 10. When the furnace body 10 is in the cooling process, the fan 50 is activated. At this time, one side of the pressure plate is in a negative pressure state. Under the action of atmospheric pressure, the cover plate 13 compresses the spring 14, separating the cover plate 13 from the through-slots and unblocking the air inlet 12, thereby ensuring the normal operation of the fan 50.

[0067] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
