Description

Technical Field

[0001] This utility model relates to the field of aluminum material processing technology, and in particular to an aluminum rod homogenizing furnace. Background Technology

[0002] Homogenizing furnaces are a key heat treatment device in the current industrial field. They are mainly used to eliminate internal stress in materials and improve the uniformity of the microstructure. They are widely used in tempered glass testing and metal material processing. In metal material processing, homogenizing furnaces optimize the heat treatment process, eliminate dendritic segregation and internal stress in metal materials, and improve the mechanical and processing properties of the materials.

[0003] Currently, the homogenization process for aluminum rods typically involves placing multiple aluminum rods in a container and then conveying them to a homogenizing furnace via a conveying mechanism. After the furnace is closed, homogenization begins. The inventors discovered that although the temperature inside the homogenizing furnace is controlled within a certain range, the temperature varies in different areas due to the location of the heat source. This results in different heat treatment temperatures for the aluminum rods in different areas, ultimately leading to variations in the homogenization effect in different areas of the same aluminum rod, which in turn affects the uniformity of the aluminum rod's microstructure and mechanical properties. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an aluminum rod homogenizing furnace, which solves the problem that the heat treatment temperature of aluminum rods varies in different areas of the homogenizing furnace, affecting the performance of the aluminum rods after homogenization.

[0005] According to an embodiment of this utility model, an aluminum rod homogenizing furnace includes a furnace body, a base, and a circulating fan. The furnace body has an opening on one side, and a closed door is vertically and slidably provided at the opening. The top of the furnace body is provided with a lifting assembly for driving the closed door to open or close the opening. The inner wall of the furnace body is provided with several nozzles for providing heat energy to the interior of the furnace body.

[0006] Compared with the prior art, this utility model has the following beneficial effects: by setting a base inside the furnace, the aluminum rod to be heat-treated is placed in a disc on the base. When the aluminum rod is heat-treated, the lifting component drives the sealing door to close the furnace opening, and the driving component drives the turntable to rotate, so that the aluminum rod changes continuously. Different areas of the aluminum rod can be evenly affected by heat energy, and the circulating fan mixes the heat energy of different areas inside the furnace evenly and forms a circulation, so that different areas of the aluminum rod are affected by heat energy at a constant temperature, thereby ensuring the heat treatment quality of the aluminum rod.

[0007] Furthermore, the drive assembly includes: a first motor, which is fixedly embedded in the bottom of the inner wall of the furnace, and a gear is provided vertically upward at the output end of the first motor. An outer gear ring is fixedly sleeved on the outer wall of the turntable, and the gear meshes with the outer gear ring.

[0008] Furthermore, the bottom of the base is equipped with a slider, and the bottom of the inner wall of the furnace body is provided with a sliding groove for the slider to slide. The base is slidably set in the furnace body by the slider, and the furnace body is also equipped with a limiting component to restrict the sliding of the base.

[0009] Furthermore, the limiting component includes: a first push rod, there are two first push rods, the two first push rods are symmetrically arranged on both sides of the inner wall of the furnace body, each first push rod has a limiting plate at its output end, each limiting plate has a limiting structure at the end of the first push rod, and both ends of the base have limiting grooves that cooperate with the limiting triangle.

[0010] Furthermore, the lifting assembly includes: a mounting frame, which is fixedly mounted on the top of the furnace body. Two mounting blocks are symmetrically arranged on the top of the mounting frame, and a winding roller is rotatably arranged between the two mounting blocks. A pull rope is wound on the winding roller, and the free end of the pull rope is vertically downward and connected to the closed door. A second motor is also fixedly mounted on the mounting frame, and the output end of the second motor is fixedly connected to the winding roller.

[0011] Furthermore, at least one sealing block is symmetrically provided at both ends of the closed door, and sealing grooves adapted to the sealing blocks are symmetrically provided on the inner wall of the furnace body opening.

[0012] Furthermore, it also includes a second push rod, which is embedded in the top wall of the furnace body near the closed door. A mounting plate is fixed on the output end of the second push rod, and a sealing strip is provided on the side of the mounting plate away from the second push rod. A slot for the sealing strip to be inserted is opened on the side of the closed door facing the second push rod.

[0013] Furthermore, two arc-shaped blocks are symmetrically arranged on one side of the closed door facing the furnace body. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes an aluminum rod homogenizing furnace, including a furnace body 1, a base 3, and a circulating fan 5. The furnace body 1 has an opening on one side, and a vertically sliding sealing door 2 is provided at the opening. A lifting assembly for driving the sealing door 2 to open or close the opening is provided at the top of the furnace body 1. Several nozzles for providing heat energy to the interior of the furnace body 1 are provided on the inner wall of the furnace body 1. The base 3 is disposed inside the furnace body 1, and a turntable 4 is rotatably provided on the top of the base 3. A driving assembly for driving the turntable 4 to rotate is provided inside the furnace body 1. The circulating fan 5 is disposed at the end of the furnace body 1 away from the sealing door 2, and the output end of the circulating fan 5 faces the sealing door 2. It should be noted that the nozzles of the homogenizing furnace, also called burners or burners, are an important component of the homogenizing furnace heating system. Its main function is to generate high-temperature flames and flue gas by burning fuels (such as natural gas, diesel, etc.) to provide heat to the furnace chamber inside the furnace body 1, thereby heating the materials inside the furnace, such as aluminum rods, to meet the requirements of the heat treatment process. The specific heating principle is existing technology and will not be elaborated here. As needed, the rotating disc can be stacked to form multiple layers through connecting shafts. Before homogenization, the closing door 2 is opened by the lifting assembly, and then the aluminum rods are placed on the corresponding frames to achieve stable placement. Then, the frames with aluminum rods are placed on the turntable 4, and the lifting assembly lowers the closing door 2 to make the furnace body 1... When the opening is closed, the nozzle sprays out a large amount of heat during the subsequent operation of the furnace body 1. At this time, the circulating fan 5 and the drive assembly are started. The drive assembly drives the turntable 4 to rotate, causing the aluminum rod placed on the turntable 4 to continuously change its position. This changes the relative position of different areas of the aluminum rod with respect to the nozzle, achieving the purpose of uniform heating of the aluminum rod. The circulating fan 5 blows the hot air inside the furnace body 1, thereby mixing the heat from different areas and improving the temperature uniformity inside the furnace body 1. This ensures that the chemical composition and microstructure of the aluminum rod after homogenization are more uniform, thus improving product quality.

[0022] like Figure 3As shown, the driving assembly further includes: a first motor 6, which is fixedly embedded in the bottom of the inner wall of the furnace body 1; a gear 7 is vertically upwardly mounted on the output end of the first motor 6; and an external gear ring 8 is fixedly mounted on the outer wall of the turntable 4, with the gear 7 meshing with the external gear ring 8. It should be noted that the output end of the first motor 6 is also equipped with a reducer, causing the gear 7 to rotate at a low speed. When the turntable 4 is driven to rotate, the first motor 6 is activated, causing the gear 7 to rotate, which in turn drives the meshing external gear ring 8 to rotate, thereby causing the aluminum rod placed on the turntable 4 to rotate, ensuring that different positions of the aluminum rod are heated evenly.

[0023] like Figure 1 and Figure 4 As shown, the bottom of the base 3 is further provided with a slider, and the bottom of the inner wall of the furnace body 1 is provided with a sliding groove for the slider to slide. The base 3 is slidably set inside the furnace body 1 by the slider. The furnace body 1 is also provided with a limiting component to restrict the sliding of the base 3. In order to facilitate the placement of aluminum rods onto the turntable 4, the base 3 is slidably connected to the bottom of the inner wall of the furnace body 1 by the slider. When placing aluminum rods, the base 3 can be slid out to the outside of the furnace body 1 for easy placement. After placement, the base 3 is slid back into the furnace body 1. The limiting component plays a role in limiting and positioning, so that when the base 3 moves to the predetermined position inside the furnace body 1, the outer gear ring 8 can mesh with the gear 7.

[0024] like Figure 4 As shown, the limiting component further includes: two first push rods 9, which are symmetrically arranged on both sides of the inner wall of the furnace body 1. Each first push rod 9 has a limiting plate 10 at its output end, and each limiting plate 10 has a limiting structure 11 at its end away from the first push rod 9. Both ends of the base 3 have limiting grooves that cooperate with the limiting triangle. Specifically, in this embodiment, the limiting structure 11 has an isosceles trapezoidal cross section, and the limiting groove is triangular. When the first push rod 9 pushes the limiting plate 10 to move towards the limiting groove, the limiting structure 11 is inserted into the limiting groove, and the two sides of the isosceles trapezoid cooperate with the two sides of the limiting groove, thereby restricting the movement of the base 3 and allowing the external gear ring 8 to mesh with the gear 7. It should be noted that, in order to ensure that the teeth of the external gear ring 8 are just inserted between the teeth of the gear 7, the gear 7 can be controlled to rotate slightly by setting appropriate sensors, controllers, etc., to adapt to the insertion of the external gear ring 8.

[0025] like Figure 1 and Figure 2As shown, the lifting assembly further includes: a mounting frame 12, which is fixedly mounted on the top of the furnace body 1. Two mounting blocks 13 are symmetrically arranged on the top of the mounting frame 12, and a winding roller 14 is rotatably mounted between the two mounting blocks 13. A pull rope 15 is wound onto the winding roller 14, and the free end of the pull rope 15 is vertically downward and connected to the closed door 2. A second motor 16 is also fixedly mounted on the mounting frame 12, and the output end of the second motor 16 is fixedly connected to the winding roller 14. In this embodiment, the mounting frame 12 has an inverted concave structure, and there are two pull ropes 15, both wound onto the winding roller 14. A through hole is provided on the mounting frame 12 for the pull ropes 15 to pass through. When the closed door 2 is opened, the second motor 16 is started. The second motor 16 drives the winding roller 14 to rotate, causing the winding roller 14 to wind up the pull rope 15, thereby raising the horizontal height of the closed door 2 and opening the furnace body 1. When closing, the closed door 2 closes the opening under its own weight by releasing the pull rope 15.

[0026] like Figure 1 and Figure 2 As shown, furthermore, at least one sealing block 17 is symmetrically provided at both ends of the closed door 2, and sealing grooves adapted to the sealing blocks 17 are symmetrically provided on the inner wall of the furnace body 1 at the opening. In this embodiment, the closed door 2 slides vertically through the sealing blocks 17 and the sealing grooves. When the closed door 2 closes the furnace body 1, the presence of the sealing blocks 17 increases the path connecting the inside and outside of the furnace body 1, achieving a better sealing effect on the furnace body 1.

[0027] like Figure 5 As shown, furthermore, it also includes a second push rod 18, which is embedded in the top wall of the furnace body 1 near the closed door 2. A mounting plate 19 is fixedly mounted on the output end of the second push rod 18. A sealing strip 20 is provided on the side of the mounting plate 19 facing away from the second push rod 18. A slot 21 for the sealing strip to be inserted is provided on the side of the closed door 2 facing the second push rod 18. To further improve the sealing effect, when the closed door 2 descends to its lowest point and closes the opening of the furnace body 1, the sealing strip 20 and the slot 21 are at the same horizontal level. Activating the second push rod 18 pushes the mounting plate 19 to move, causing the sealing strip 20 on the mounting plate 19 to insert into the slot 21. This results in a better seal between the closed door 2 and the top of the furnace body 1, ensuring that heat inside the furnace body 1 is not easily dissipated.

[0028] like Figure 2 As shown, furthermore, two arc-shaped blocks 22 are symmetrically arranged on the side of the closed door 2 facing the inside of the furnace body 1. Specifically, the arc surface of the arc-shaped block 22 faces the inside of the furnace body 1. The presence of the arc-shaped block 22 helps to guide the hot air blown by the circulating fan 5 to the other side, so that the hot air can circulate in the furnace body 1.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
