Description

Technical Field

[0002] Annealing furnaces are equipment used for heat treatment of metals, mainly to change the crystal structure and properties of materials. They are suitable for heat treatment of aluminum alloy materials, such as aluminum tubes. They can perform annealing heat treatment on aluminum tube workpieces. There are many types of annealing furnaces, including annealing machines that process aluminum tube workpieces through electric heating coils. When in use, the aluminum tube workpiece passes through the electric heating coil. During the entire heating process, the aluminum tube workpiece will pass through the electric heating coil to complete the slow heating of the aluminum tube workpiece.

[0003] In the above process of heating aluminum tube workpieces, the aluminum tube workpiece is placed inside the electric heating coil, and part of the aluminum tube workpiece is in contact with the inside of the electric heating coil. The temperature of the electric heating coil rises and heats the aluminum tube workpiece. However, because the aluminum tube workpiece is in contact with the electric heating coil, the aluminum tube workpiece is heated unevenly, which can easily lead to changes in the structure and performance of the aluminum tube workpiece, which is called a defective workpiece.

[0004] Existing annealing furnaces that use electric heating coils to heat aluminum tube workpieces have a design problem where the suspended aluminum tube workpieces are not supported. To address this, this application proposes a through-type annealing furnace for aluminum tube processing. Utility Model Content

[0023] 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.

[0024] Example

[0025] Please see Figures 1 to 4This utility model provides a technical solution: a through-type annealing furnace for aluminum tube processing, including an annealing furnace device for heating aluminum tube workpiece C, including an annealing furnace machine 11 and an electric heating coil 12 connected to the annealing furnace machine 11. The technical principle of the annealing furnace machine 11 using the electric heating coil 12 to heat the aluminum tube workpiece C is a publicly disclosed technology, and this application will not describe the use of the annealing furnace in detail; the fixing frame includes a mounting plate 21 connected to the side of the annealing furnace machine 11, a fixing frame 22 connected to one end of the mounting plate 21, and a through fixing frame 2... The pressing rod 23 and the return spring 24 sleeved on the outside of the pressing rod 23 are connected to the mounting plate 21, the annealing furnace machine 11, and the fixing frame 22 by conventional means (such as screw connection). Pressing down the pressing rod 23 causes the return spring 24 to be in a retracted state, which can change the height position of the connecting plate 31, thereby changing the height position of the lifted aluminum tube workpiece C, suitable for aluminum tube workpieces C of different diameters. A fixing component is sleeved on the outside of the pressing rod 23, which includes a fixing ring sleeved on the outside of the pressing rod 23. 41. A symmetrically mounted inclined plate 42 on the outer surface of the fixed ring 41, and a fixed cylinder 43 connected to one end of the inclined plate 42. The fixed ring 41 and the pressing rod 23 are combined by conventional means (such as screw connection). The inclined plate 42 is welded to the fixed ring 41 and the fixed cylinder 43. The inclined plate 42 acts as a lever to move the limiting head 53. The fixed frame 22 is equipped with a limiting component inside. The limiting component consists of the fixed rod 51, the spring spring 52, and the limiting head 53. The limiting head 53 is embedded in the slot 431, which can limit the movement of the fixed cylinder 43. To limit the movement of the pressing rod 23, a return spring 24 with different elastic forces can be selected according to the actual situation; the lifting assembly supporting the aluminum tube workpiece C includes a connecting plate 31 rotatably connected to the bottom end of the pressing rod 23, a stabilizing plate 32 connected to the bottom end of the connecting plate 31, and a supporting roller 33 installed between the opposing surfaces of the stabilizing plate 32. The connecting plate 31 and the stabilizing plate 32 are connected by screws. The supporting roller 33 supports the aluminum tube workpiece C, allowing it to be suspended inside the electric heating coil 12, so that it is heated evenly.

[0026] In this embodiment, the limiting component includes a fixing rod 51 installed on the inner surface of the fixing frame 22, a spring 52 sleeved on the outside of the fixing rod 51, and a limiting head 53 connected to one end of the spring 52. The fixing rod 51 and the fixing frame 22 are connected by screws. One end of the spring 52 is embedded in the interior of the fixing frame 22. The spring 52 is welded to the limiting head 53. The limiting head 53 is a right-angled triangular structure, and the inclined surface of the limiting head 53 is curved. The curved inclined surface of the limiting head 53 is smooth, which facilitates the downward movement of the fixing cylinder 43. When the limiting head 53 moves downward, the spring 52 is in a deformed state, and the fixing cylinder 43 moves away from the limiting head 53. Under the elastic force of the spring 52, the limiting head 53 returns to its original position and limits the fixing cylinder 43. The outer surface of the fixing cylinder 43 is provided with a concave right-angled triangular groove 431, and the limiting head 53 is located inside the corresponding groove 431.

[0027] In this embodiment, the mounting plate 21 has an "L" shaped structure, the fixing frame 22 has a frame structure, and a rectangular groove a is provided at the center of the bottom surface of the fixing frame 22. The fixing ring 41 and the inclined plate 42 pass through the rectangular groove a, which does not affect the downward movement of the pressing rod 23.

[0028] In this embodiment, the top of the pressing rod 23 has a "T" shaped structure, and a compression ring is provided on the outer side of the pressing rod 23 near the top. The two ends of the return spring 24 are connected to the fixed frame 22 and the compression ring respectively. The connecting plate 31 and the stabilizing plate 32 have a "U" shaped structure. The compression ring can compress the return spring 24, which is conducive to the retraction of the return spring 24.

[0029] In this embodiment, a fixed shaft 321 is provided between the opposing surfaces of the stabilizing plate 32, which passes through the supporting roller 33. The fixed shaft 321 limits the supporting roller 33. A guide rod is provided on the top surface of the connecting plate 31, which is embedded in the fixed frame 22. The guide rod plays a limiting role and prevents the downward-moving connecting plate 31 from tilting.

[0030] Working principle and usage process of this utility model:

[0031] When the electric heating coil 12 of the annealing furnace heats the aluminum tube workpiece C, the aluminum tube workpiece C is placed on the supporting roller 33 and passes through the electric heating coil 12.

[0032] When used for aluminum tube workpieces C of different sizes, press down and move the pressing rod 23 down. The return spring 24 is in a contracted state, which can change the height position of the connecting plate 31, thereby changing the height position of the lifted aluminum tube workpiece C, which is suitable for aluminum tube workpieces C of different diameters.

[0033] When the pressing rod 23 moves down, the fixing ring 41 and the inclined plate 42 move down through the rectangular groove a;

[0034] When the fixed cylinder 43 moves down, it moves the limiting head 53. When the limiting head 53 moves down, the return spring 52 is in a deformed state and generates elastic force. If the fixed cylinder 43 moves away from the limiting head 53, the limiting head 53 returns to its original position under the elastic force of the return spring 52, and the limiting head 53 limits the fixed cylinder 43.

[0035] In summary: The annealing furnace is designed to support suspended aluminum tube workpieces. The aluminum tube workpiece C is placed on the supporting roller 33, which allows it to be suspended inside the electric heating coil 12, ensuring uniform heating. Pressing down the pressing rod 23 changes the height of the connecting plate 31, thereby changing the height of the lifted aluminum tube workpiece C, making it suitable for aluminum tube workpieces C of different diameters.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
