Description

Technical Field

[0001] This invention relates to the field of materials processing technology, and specifically to a heat treatment apparatus and method for aluminum alloy materials. Background Technology

[0002] Aluminum alloys are widely used in numerous industrial fields, including aerospace, rail transportation, automotive manufacturing, and electronics and communications, due to their advantages such as low density, high specific strength, good corrosion resistance, excellent electrical and thermal conductivity, and ease of processing and forming. These applications often require aluminum alloy components to have complex shapes and excellent comprehensive mechanical properties. Hot working is one of the key processes for forming high-performance aluminum alloy parts. Through heating, the plasticity of aluminum alloys is greatly improved, and the deformation resistance is significantly reduced, allowing them to be extruded or forged into the required complex shapes using molds.

[0003] In the existing technology, conventional aluminum alloy hot working equipment usually uses an independent heating furnace (such as the RX3 trolley-type resistance furnace) to heat the aluminum material (aluminum rod) as a whole. The induction coil (such as iron-chromium-aluminum alloy) is used as the heating element. The induction coil slowly transfers heat to the aluminum material placed statically in the furnace by generating heat convection and heat radiation. After it reaches the predetermined temperature, it is transferred to the extrusion press or forging press by the conveying equipment (such as a robot or conveyor) for processing.

[0004] Since the heat generated by the induction coil is directly related to its diameter, and the diameter of the induction coil varies at different locations due to the influence of processing precision, the temperature in different areas of the heating furnace varies. In existing heat treatment devices, both the aluminum material and the heating furnace remain stationary during processing, resulting in different heating efficiencies in different parts of the aluminum material, which seriously affects the heat treatment effect of the aluminum material. Therefore, it is necessary to propose a heat treatment device and method for aluminum alloy materials that can adjust the position of the aluminum material and the heating furnace to improve the uniformity of aluminum material heating. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a heat treatment apparatus and method for aluminum alloy materials. Through the design of the threaded rod and threaded sleeve, the aluminum material can be moved uniformly within the heating furnace, while simultaneously rotating the heating furnace, thereby effectively improving the heating uniformity of the aluminum material and enhancing the heat treatment effect.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A hot processing device for aluminum alloy materials includes an extrusion device for pressing aluminum materials and a conveying device for transferring heated aluminum materials to the outlet of the extrusion device. It also includes a base, a fixed seat fixedly connected to the top of the base, a threaded sleeve rotatably fitted inside the fixed seat, a threaded rod threadedly fitted to the inner wall of the threaded sleeve, and an arc-shaped plate fixedly connected to the side wall of the threaded rod. A heating furnace is provided on the side of the threaded rod near the arc-shaped plate, and a feed inlet is opened on the side of the heating furnace near the arc-shaped plate. A heating component for heating the aluminum materials is provided inside the heating furnace.

[0007] The base is fixedly connected to an inclined storage platform. The top of the threaded sleeve is equipped with a pusher plate. The height of the storage platform near the pusher plate is lower than the height of the side away from the pusher plate. The top of the fixed seat is equipped with a pusher assembly for driving the pusher plate to move back and forth along the top of the storage platform, thereby pushing the aluminum material in the storage platform into the arc plate in sequence. The conveying equipment is located on the side of the arc plate away from the pusher plate.

[0008] The base is equipped with a drive assembly for driving the arc plate to push the material into the heating furnace and move it back and forth, while driving the heating furnace to rotate.

[0009] The basic principle of adopting the above scheme is as follows:

[0010] Aluminum materials are placed on top of the storage platform. The pusher component drives the pusher plate, which pushes the aluminum materials in the storage platform into the curved plate in sequence. The drive component drives the curved plate, which pushes the aluminum materials into the heating furnace through the feed port and moves back and forth. At the same time, the drive component drives the heating furnace to rotate, thereby heating the aluminum materials evenly in sequence.

[0011] The above approach has the following beneficial effects:

[0012] 1. In the prior art, when heating aluminum, since both the aluminum and the heating furnace remain stationary, and the temperature varies in different areas of the heating furnace, it is easy to cause uneven heating of the aluminum, which seriously affects the heat processing effect of the aluminum. The present invention, through the design of the arc plate, can drive the aluminum to move back and forth in the heating furnace, so that the aluminum is heated evenly in all positions, effectively improving the heat processing effect of the aluminum.

[0013] 2. Unlike existing technologies, this invention not only drives the aluminum material to move back and forth in the heating furnace, but also drives the heating furnace to rotate, thereby making the heating temperature in each area of ​​the heating furnace more uniform and further improving the heat processing effect of the aluminum material.

[0014] 3. This invention, through the design of the pusher plate, enables aluminum materials to be pushed sequentially into the arc-shaped plate, thereby achieving independent heating of each aluminum material and further improving the heating uniformity of the aluminum materials. This invention can synchronize the filling, heating, and rotation of the heating furnace, improving the thermal processing efficiency of aluminum materials while reducing the thermal processing cost.

[0015] Furthermore, the drive assembly includes a slider that slides laterally with the top of the base, the sidewall of the slider being fixedly connected to the end of the threaded rod away from the arc plate, and a power assembly for driving the slider to slide laterally along the top of the base is provided on the base.

[0016] Beneficial effects: This solution, through the design of the slider, can drive the threaded rod to slide laterally within the fixed seat, thereby driving the sliding sleeve to rotate, thus pushing the aluminum material to move back and forth within the heating furnace, while simultaneously driving the heating furnace to rotate.

[0017] Furthermore, the power assembly includes a controller and a drive unit fixedly connected to the top of the base. A first rod is fixedly connected to the output shaft of the drive unit, and a second rod is fixedly connected to the end of the first rod away from the drive unit. The end of the second rod away from the first rod is hinged to the side of the slider away from the threaded rod. The controller is used to drive the drive unit to run, thereby causing the first rod to rotate.

[0018] Beneficial effects: This solution, through the design of the first and second links, can transmit the power generated by the drive component to the slider, enabling the slider to slide laterally back and forth stably along the top of the base.

[0019] Furthermore, the heating assembly includes an induction coil fixedly connected to the inner wall of the heating furnace, and a controller for adjusting the heating temperature of the induction coil; several connecting rods are fixedly connected to the feed inlet, and the ends of the connecting rods away from the heating furnace are fixedly connected to threaded sleeves; a support assembly for supporting the heating furnace is provided at the bottom of the heating furnace.

[0020] Beneficial effects: This solution, through the design of the connecting rod, enables the heating furnace to rotate with the rotation of the threaded sleeve, thereby achieving dynamic and uniform heating of the aluminum rod.

[0021] Furthermore, the support assembly includes an arc-shaped platform fixedly connected to the top of the base, with the top of the arc-shaped platform rotating in conjunction with the heating furnace.

[0022] Beneficial effect: The curved platform can support the heating furnace and ensure its stability.

[0023] Furthermore, the pusher assembly includes a toothed ring fixedly sleeved on the outer wall of the threaded sleeve, a sliding plate slidably fitted on the top of the fixed base, a rack fixedly connected to the side of the sliding plate near the toothed ring, the rack meshing with the toothed ring; the side of the rack away from the sliding plate rotatably engages with the pusher plate; the rack is provided with a limiting component for limiting the pusher plate, so that the pusher plate can only rotate towards the side closer to the arc plate; the rack is also provided with a lubrication component for lubricating the aluminum material.

[0024] Beneficial effects: This solution, through the design of the toothed ring and toothed plate, can utilize the sliding of the threaded rod to drive the pusher plate to push the aluminum material, thereby achieving uniform conveying of the aluminum material.

[0025] Furthermore, the limiting component includes a limiting rod fixedly connected to the rack on the side away from the slide plate, the limiting rod being located on the side of the pusher plate away from the curved plate.

[0026] Beneficial effects: This solution, through the design of the limiting rod, ensures that the pusher plate will only push the aluminum material from the top of the storage platform into the curved plate, and will not push it in the opposite direction, thus ensuring the rationality of the aluminum material pushing.

[0027] Furthermore, the lubrication assembly includes a reservoir for storing lubricating fluid, a piston rod is fixedly connected to the side of the slide plate near the reservoir, a piston plate is fixedly connected to the end of the piston rod away from the slide plate, the piston plate slides laterally with the inner wall of the reservoir, and a spraying assembly for spraying lubricating fluid onto the aluminum material is provided on the side wall of the reservoir.

[0028] Beneficial effects: This solution, through the design of the liquid storage tank and the movement of the sliding plate, realizes the delivery of lubricating fluid, which can effectively reduce the friction of aluminum materials during transportation and reduce the loss of aluminum materials.

[0029] Furthermore, the spraying assembly includes several spray holes opened on the top of the storage platform, all of which are connected to the storage tank, and a first check valve for draining liquid is connected at the connection point between the two; an air inlet is opened on the side wall of the storage tank away from the piston rod, and a second check valve for air intake and replenishment of lubricating fluid is connected at the air inlet.

[0030] Beneficial effects: This solution, through the design of the spray nozzle, allows the lubricant to be sprayed out from the top of the storage platform. By utilizing the inclination of the storage platform, the lubricant is spread all over the top of the storage platform, so that the aluminum material can fully contact the lubricant when it rolls along the top of the storage platform, thereby ensuring the lubrication effect.

[0031] Furthermore, a hot working method for aluminum alloy materials includes the following steps:

[0032] S1, Material filling and lubrication: Fill the storage tank with lubricant, place several aluminum materials on top of the storage platform, and apply lubricant to the aluminum materials on top of the storage platform through the spray nozzle.

[0033] S2, Aluminum Material Pushing: The aluminum material at the top of the storage platform is pushed sequentially into the curved plate using a pusher plate.

[0034] S3, Aluminum heating: Adjust the heating temperature of the induction coil, start the induction coil, use the arc plate to drive the aluminum material to move back and forth in the heating furnace, and use the threaded sleeve to drive the heating furnace to rotate around the aluminum material to obtain the heated aluminum material.

[0035] S4, Aluminum Material Conveying and Pressing: The heated aluminum material is moved outside the heating furnace by the curved plate, the unheated aluminum material is pushed into the curved plate by the pusher plate and the heated aluminum material is pressed to the conveying equipment by the conveying equipment, and the heated aluminum material is conveyed to the extrusion equipment by the extrusion equipment to obtain the extruded profile.

[0036] S5, Post-processing: The extruded profile is subjected to online quenching, tensile straightening and aging heat treatment to obtain the finished product.

[0037] Beneficial effects: Compared with traditional static heating, this method can drive the aluminum material to move evenly in the heating furnace during the heating process, which effectively improves the uniformity of aluminum material heating. At the same time, it keeps the heating furnace rotating evenly. Through this heating method, the temperature in all parts of the heating furnace is kept uniform, which further improves the uniformity of aluminum material heating and improves the heat processing effect.

[0038] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0048] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] The following detailed description illustrates the specific implementation method:

[0050] Example 1:

[0051] As attached Figure 1 and Figure 2 As shown: A hot working device for aluminum alloy materials includes an extrusion device for pressing aluminum material (in this embodiment, an aluminum rod with a diameter of 80 mm and a length of 0.8 m is selected) and a conveying device 25 for conveying the heated aluminum material to the outlet of the extrusion device. In this embodiment, the extrusion device is a horizontal double-acting extruder in the prior art, and the conveying device 25 is a chain plate conveyor in the prior art.

[0052] The aluminum alloy material hot processing device also includes a base 1, with a fixed seat 2 bolted to the top of the base 1. A threaded sleeve 3 is rotatably fitted inside the fixed seat 2, and a threaded rod 4 is threaded into the inner wall of the threaded sleeve 3. An arc-shaped plate 5 (whose size can be adjusted according to the size of the aluminum material being processed; in this embodiment, the arc-shaped plate 5 is 0.8m long) is bolted to the side of the threaded rod 4 near the arc-shaped plate 5. A heating furnace 6 (in this embodiment, the heating furnace 6 is 1.6m long) is located on the side of the threaded rod 4 near the arc-shaped plate 5. A feed inlet is opened on the side of the heating furnace 6 near the arc-shaped plate 5. A heating assembly for heating the aluminum material is installed inside the heating furnace 6. The heating assembly includes an induction coil embedded in the inner wall of the heating furnace 6. A controller is used to adjust the heating temperature of the induction coil (460-500℃). Several connecting rods 13 are bolted to the feed inlet, and the ends of the connecting rods 13 away from the heating furnace 6 are all bolted to the threaded sleeve 3. A support assembly for supporting the heating furnace 6 is provided at the bottom of the heating furnace 6.

[0053] like Figure 1 As shown, the top of the base 1 is bolted to a storage platform 7 (capable of storing at least 5 aluminum bars) that is inclined. The top of the threaded sleeve 3 is provided with a pusher plate 8. The height of the storage platform 7 near the pusher plate 8 is lower than the height of the side away from the pusher plate 8 (inclined by about 10°). The top of the fixed seat 2 is provided with a pusher assembly for driving the pusher plate 8 to move back and forth along the top of the storage platform 7, thereby pushing the aluminum materials in the storage platform 7 to the arc plate 5 in sequence. The conveying device is located on the side of the arc plate 5 away from the pusher plate 8.

[0054] like Figure 2 As shown, the base 1 is equipped with a drive assembly for driving the arc plate 5 to push the material into the heating furnace 6 and move it back and forth, while driving the heating furnace 6 to rotate.

[0055] The drive assembly includes a slider 9 that slides laterally with the top of the base 1. The side wall of the slider 9 is bolted to the end of the threaded rod 4 away from the arc plate 5. The base 1 is provided with a power assembly for driving the slider 9 to slide laterally along the top of the base 1.

[0056] The power assembly includes a controller and a drive unit 10 (a DC motor is selected in this embodiment) that is bolted to the top of the base 1. A first rod 11 is bolted to the output shaft of the drive unit 10. A second rod 12 is bolted to the end of the first rod 11 away from the drive unit 10. The end of the second rod 12 away from the first rod 11 is hinged to the side of the slider 9 away from the threaded rod 4. The controller is used to drive the drive unit 10 to run, thereby driving the first rod 11 to rotate.

[0057] like Figure 3As shown, the pusher assembly includes a toothed ring 15 fixedly sleeved on the outer wall of the threaded sleeve 3, a sliding plate 16 slidably fitted on the top of the fixed base 2, a rack 17 bolted to the side of the sliding plate 16 near the toothed ring 15, the rack 17 meshing with the toothed ring 15; the side of the rack 17 away from the sliding plate 16 rotatably engages with the pusher plate 8; the rack 17 is provided with a limiting component for limiting the pusher plate 8, so that the pusher plate 8 can only rotate towards the side near the arc plate 5; the limiting component includes a limiting rod 18 bolted to the side of the rack 17 away from the sliding plate 16, the limiting rod 18 being located on the side of the pusher plate 8 away from the arc plate 5.

[0058] Specifically, such as Figure 3 As shown, before starting the hot processing, the user places several aluminum bars on the top of the storage platform 7. Since the storage platform 7 is tilted, the aluminum bars will roll to the left side of the storage platform 7 and be stacked in sequence.

[0059] like Figure 3 and Figure 4 As shown, in the initial state, the slider 9 is away from the fixed base 2, the first rod 11 is located to the left of the drive component 10, and the pusher plate 8 is located to the left of the storage platform 7. When the hot working begins, the user starts the drive component 10; when the output shaft of the drive component 10 drives the first rod 11 to rotate to the right, the first rod 11 will push the second rod 12 to move to the right, thereby pushing the slider 9 and the threaded rod 4 to slide to the right, as shown. Figure 6 and Figure 7 As shown, since the threaded sleeve 3 is rotatably engaged with the fixed seat 2, and the threaded rod 4 is threadedly engaged with the threaded sleeve 3, when the threaded rod 4 slides to the right, it will drive the threaded sleeve 3 to rotate clockwise, thereby driving the connecting rod 13, the heating furnace 6, and the induction coil to rotate clockwise. During this process, the threaded sleeve 3 will drive the toothed ring 15 to rotate clockwise, thereby driving the pusher plate 8 to move to the right (the moving distance of the pusher plate 8 is approximately the diameter of the aluminum rod). During the process of the pusher plate 8 moving to the right, since the pusher plate 8 is rotatably engaged with the rack 17, the pusher plate 8 will rotate clockwise under the limiting action of the first aluminum rod on the top left of the storage platform 7 until the pusher plate 8 moves to the right side of the aluminum rod, the limiting effect of the pusher plate 8 disappears, and the bottom of the pusher plate 8 will fall into the gap between the adjacent aluminum rods.

[0060] When the drive unit 10 continues to rotate, the output shaft of the drive unit 10 drives the first rod 11 to rotate to the left. The first rod 11 will pull the second rod 12 to move to the left, which in turn pulls the slider 9 and the threaded rod 4 to slide to the left. The threaded rod 4 will drive the threaded sleeve 3 and the toothed ring 15 to rotate counterclockwise, which will drive the connecting rod 13, the heating furnace 6, and the induction coil to rotate counterclockwise, thereby making the temperature in the heating furnace 6 uniform. The toothed ring 15 will drive the rack 17 and the pusher plate 8 to move to the left. At this time, due to the limiting action of the limiting rod 18, the pusher plate 8 cannot rotate counterclockwise. The pusher plate 8 will push the first aluminum rod on the top left of the storage platform 7 into the arc plate 5. Since the threaded rod 4 will slide back and forth along the fixed seat 2 under the push of the slider 9, the threaded rod 4 will push the arc plate 5 and the aluminum rod to move back and forth in the heating furnace 6, thereby making the aluminum rod uniformly heated.

[0061] As the drive unit 10 continues to rotate, the pusher plate 8 pushes the unheated aluminum rod into the arc plate 5 and presses the heated aluminum rod to the top of the conveyor 25, which then conveys it to the extrusion equipment for pressing.

[0062] like Figure 1 As shown, the support assembly includes an arc-shaped platform 14 bolted to the top of the base 1, and the top of the arc-shaped platform 14 is rotatably engaged with the heating furnace 6.

[0063] Specifically, during the rotation of the heating furnace 6, the arc-shaped platform 14 can support the heating furnace 6 and ensure its stability.

[0064] like Figure 1 and Figure 5 As shown, the rack 17 is also equipped with a lubrication assembly for lubricating the aluminum material. The lubrication assembly includes a reservoir 19 for storing lubricating fluid. A piston rod 20 is bolted to the side of the slide plate 16 near the reservoir 19. A piston plate 21 is bolted to the end of the piston rod 20 away from the slide plate 16. The piston plate 21 slides laterally against the inner wall of the reservoir 19. The side wall of the reservoir 19 is equipped with a spraying assembly for spraying lubricating fluid onto the aluminum material. The spraying assembly includes several spray holes 22 opened at the top of the storage platform 7. All spray holes 22 are connected to the reservoir 19, and a first one-way valve 23 for draining fluid is connected at the connection point. An air inlet is opened on the side wall of the reservoir 19 away from the piston rod 20, and a second one-way valve 24 for air intake and replenishment of lubricating fluid is connected at the air inlet.

[0065] Specifically, such as Figure 5As shown, before hot processing, the user can add lubricant to the reservoir 19 through the second one-way valve 24. During hot processing, when the rack 17 moves back and forth under the drive of the gear ring 15, the rack 17 will push the piston rod 20 and the piston plate 21 to move back and forth in the reservoir 19. When the piston plate 21 moves to the right, the piston plate 21 will transport the lubricant in the reservoir 19 to the spray hole 22 through the first one-way valve 23, thereby lubricating the aluminum rod. Due to the inclined design of the storage platform 7, the lubricant will gradually spread from the right side of the top of the storage platform 7 to its left side, covering the top of the storage platform 7, so that the aluminum rod can fully contact the lubricant when rolling along the top of the storage platform 7, thereby ensuring the lubrication effect.

[0066] In existing technologies, when heating aluminum, since both the aluminum and the heating furnace 6 remain stationary, and the temperatures in different areas within the furnace 6 vary, uneven heating of the aluminum is very likely to occur, severely affecting the heat processing effect. This solution, through the design of the arc-shaped plate 5, can drive the aluminum to move back and forth within the heating furnace 6, ensuring uniform heating of all parts of the aluminum and effectively improving the heat processing effect. Furthermore, this solution not only drives the aluminum to move back and forth within the heating furnace 6 but also drives the heating furnace 6 to rotate, thereby making the heating temperature in different areas within the heating furnace 6 more uniform, further improving the heat processing effect of the aluminum.

[0067] Example 2:

[0068] As attached Figure 8 As shown, unlike the above embodiments, a hot working method for aluminum alloy materials includes the following steps:

[0069] S1, Material filling and lubrication: Fill the storage tank 19 with lubricant, place a number of aluminum materials on the top of the storage platform 7, and apply lubricant to the aluminum materials on the top of the storage platform 7 through the spray hole 22.

[0070] S2, Aluminum Material Pushing: The aluminum material at the top of the storage platform 7 is pushed sequentially into the curved plate 5 using the pusher plate 8.

[0071] S3, Aluminum heating: Adjust the heating temperature of the induction coil, start the induction coil, use the arc plate 5 to drive the aluminum material to move back and forth in the heating furnace 6, and use the threaded sleeve 3 to drive the heating furnace 6 to rotate around the aluminum material to obtain the heated aluminum material.

[0072] S4, Aluminum Material Conveying and Pressing: The heated aluminum material is moved to the outside of the heating furnace 6 by the arc plate 5, and the unheated aluminum material is pushed into the arc plate 5 by the pusher plate 8 and the heated aluminum material is pressed to the conveying device 25. The heated aluminum material is conveyed to the extrusion device by the conveying device 25 and pressed to obtain the extruded profile.

[0073] S5, Post-processing: The extruded profile is subjected to online quenching, tensile straightening and aging heat treatment to obtain the finished product.

[0074] The specific experiment is as follows:

[0075] I. Experimental Preparation

[0076] Experimental group: Use the apparatus in this scheme for heat treatment.

[0077] Control group: Heat processing was performed using an RX3 trolley-type resistance furnace.

[0078] II. Experimental Methods

[0079] The thermal processing efficiency, maximum temperature difference in the heating zone, and maximum temperature difference in different parts of the aluminum rod were analyzed between the experimental and control groups.

[0080] III. Experimental Results

[0081] Table 1 Comparison of Hot Working Data

[0082]

[0083] Table 1 shows that the heat processing efficiency of the experimental group is significantly higher than that of the control group. This may be because the experimental group performs loading, heat processing and unloading simultaneously, and the overall coordination is better than the split design in the existing heat processing technology. The maximum temperature difference in the heating area of ​​the experimental group is lower than that in the control group. The maximum temperature difference of each part of the aluminum rod in the experimental group is also lower than that in the control group. This may be because the experimental group can rotate the heating furnace 6 and move the aluminum rod itself, which can effectively improve the temperature balance in each area of ​​the heating furnace 6 and make the aluminum rod heated evenly.

[0084] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
