Description

Technical Field

[0001] This utility model relates to the technical field of aluminum alloy plate processing equipment, and in particular to an aluminum alloy plate annealing equipment. Background Technology

[0002] Aluminum alloys, as one of the most widely used non-ferrous metal structural materials in the industrial field, have been widely applied in many fields such as aviation, aerospace, automobiles, machinery manufacturing, shipbuilding, and chemical industry.

[0003] The primary purpose of annealing aluminum alloy sheets is to eliminate work hardening, allowing for further rolling or deep processing. The annealing process not only controls the product's condition and properties but also removes rolling oil and improves surface quality. For example, in the solution treatment of 5083 aluminum alloy, rapid cooling after heating to the solution temperature dissolves the hardened phases in the alloy, allowing for a more uniform grain distribution and significantly improving the material's strength and plasticity. Furthermore, aluminum alloy annealing furnaces are the most widely used equipment in aluminum alloy heat treatment. By scientifically controlling the annealing temperature and time, internal stresses in the material can be effectively eliminated, improving its mechanical properties and corrosion resistance.

[0004] In the actual use of existing technical devices, an annealing furnace is generally rotatably connected to a support plate, with an aluminum alloy plate standing upright above the support plate. In order to prevent the position of the aluminum alloy plate from changing, the support plate is generally equipped with a corresponding clamping mechanism for the aluminum alloy plate, which is used to achieve auxiliary fixation of the aluminum alloy plate.

[0005] However, in practice, we found that regardless of the clamping mechanism used, its thermal conductivity would interfere with the heating process of the aluminum alloy plate, resulting in uneven heating time, which in turn affected the annealing effect, leaving the annealed aluminum alloy plate with residual stress concentration problems.

[0006] Therefore, we believe that there is a need for an annealing equipment that can effectively reduce the impact of the clamping mechanism on the aluminum alloy sheet, and ensure that the aluminum alloy sheet is heated evenly in the annealing furnace, thereby avoiding damage to the annealing effect. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention proposes an aluminum alloy plate annealing device. It has the advantage of ensuring uniform heating of the aluminum alloy plate and solves the problem of uneven heating caused by the influence of the clamping mechanism on the aluminum alloy plate in existing technologies.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An aluminum alloy plate annealing device includes an open-structure outer shell with a heating mechanism inside. It also includes a support substrate with an L-shaped vertical projection, embedded in an opening on the right side of the outer shell. The support substrate is slidably connected to the outer shell and can move linearly left and right relative to it. A vertically oriented positioning shaft is fixedly connected to the inner side of the support substrate. A lower contact plate is rotatably connected to the inner side of the support substrate via the positioning shaft. A driving mechanism is located inside the support substrate and is connected to the lower contact plate. The lower contact plate rotates around the central axis of the positioning shaft under the drive of the driving mechanism. The lower contact plate has two sides... Each clamping plate is provided with a clamping plate, and multiple positioning slide rails are provided near the ends of the two clamping plates. Multiple aluminum alloy plates are provided between the two clamping plates, and the multiple aluminum alloy plates correspond one-to-one with the multiple positioning slide rails. Each aluminum alloy plate is inserted into the corresponding positioning slide rail. The two clamping plates are slidably connected to the lower contact plate. A left and right displacement mechanism is provided between the two clamping plates to change the distance between each clamping plate and the lower contact plate. An upper contact plate is provided on the upper side of the inner cavity of the outer shell. The upper contact plate is rotatably connected to the outer shell. When the supporting base plate is located inside the outer shell, the multiple aluminum alloy plates abut against the lower end face of the upper contact plate.

[0010] Preferably, the left and right displacement mechanism includes two symmetrically arranged follower blocks. The projection of each follower block on the vertical plane is a right-angled triangle structure. One right-angled side of each follower block is fixedly connected to the corresponding clamping plate, and the other right-angled side of each follower block abuts against the lower contact plate. A driven plate is provided between the two follower blocks. The lower end of the driven plate abuts against the follower block. The driven plate is sleeved on the outside of the positioning shaft and is slidably connected to the positioning shaft. The driven plate moves vertically relative to the positioning shaft.

[0011] Preferably, a cylinder is fixedly connected to the upper end of the outer shell, and an adjusting plate is fixedly connected to the movable end of the cylinder. The adjusting plate is located in the inner cavity of the outer shell, and the adjusting plate is elastically connected to the upper contact plate.

[0012] Preferably, a contact shaft is provided on the lower side of the upper contact plate, the central axis of the contact shaft coincides with the central axis of the positioning shaft, and when the contact shaft abuts against the driven plate, the upper contact plate does not contact the aluminum alloy plate; when the upper contact plate abuts against the aluminum alloy plate, the clamping plate and the aluminum alloy plate are not in the same vertical plane; the contact shaft is slidably connected to the upper contact plate; and the contact shaft is fixedly connected to the adjusting plate.

[0013] Preferably, each of the lower contact plates has a through slot, and a sliding rod is inserted into the left and right sides of each through slot. Furthermore, the two sliding rods in a single through slot are fixedly connected to the two clamping plates, and a tension spring is provided near the two sliding rods in a single through slot. The two axial ends of the tension spring are movably connected to the corresponding two sliding rods.

[0014] Preferably, the upper contact plate and the lower contact plate are provided with multiple limiting grooves at their near ends, and the multiple aluminum alloy plates correspond one-to-one with the multiple limiting grooves. Furthermore, the upper and lower sides of each aluminum alloy plate are respectively inserted into the corresponding limiting groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention designs a left-right displacement mechanism that can adjust the distance between the two clamping plates and the lower contact plate to adapt to different operational needs. In practical applications, when the aluminum alloy plate is in a non-annealed state, the device can fix the aluminum alloy plate through the limiting effect of the clamping plates. During the annealing process, by moving the clamping plates and combining the clamping and fixing of the clamping plates with the upper and lower contact plates, the aluminum alloy plate can be separated from the positioning slide rail. This design cleverly avoids direct contact between the positioning slide rail and the aluminum alloy plate, effectively preventing problems caused by uneven heating of the aluminum alloy plate, ensuring uniformity in the annealing process, and thus playing a crucial role in improving the annealing effect.

[0024] 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.

[0025] In the description of this utility model, it should be understood that terms such as "upper", "lower", "front", and "rear" are based on the orientation shown in the accompanying drawings and are intended to simplify the description and facilitate understanding. They do not indicate the actual orientation, structure, or operation of the device or component and therefore do not constitute a limitation on this utility model.

[0026] Please refer to Figure 1 , Figure 2 An aluminum alloy plate annealing device is disclosed, the structure of which is consistent with existing technology devices, including an outer shell 1 with an opening on the right side, and a heating mechanism 10 disposed inside the outer shell 1. The heating mechanism 10 generally uses resistance wire; for the purpose of focusing on the core of this application, detailed descriptions of other components are omitted here.

[0027] Compared with the prior art, the present application is characterized by the addition of an L-shaped carrier substrate 3 (e.g., Figure 2 , Figure 6 The substrate is embedded in the opening on the right side of the outer casing 1 and is slidably connected to the outer casing 1.

[0028] Therefore, a corresponding slider is fixedly connected to the lower end of the carrier substrate 3. Correspondingly, a dovetail groove is opened inside the outer shell 1 for the slider. Through the mutual cooperation between the slider and the dovetail groove, the carrier substrate 3 can move linearly left and right relative to the outer shell 1.

[0029] In detail, such as Figure 2 As shown, a positioning shaft 16 perpendicular to the axial direction is fixedly connected to the inner side of the support substrate 3. The inner side of the support substrate 3 is flexibly rotatably connected to the lower contact plate 5 via the positioning shaft 16. Figure 6As shown, a bearing is provided on the outer side of the positioning shaft 16, and the bearing is embedded in the mounting hole provided in the middle section of the support base plate 3. In this way, the bearing effectively reduces the frictional resistance between the positioning shaft 16 and the support base plate 3, and at the same time, the interference fit technology ensures a stable positioning between the support base plate 3 and the positioning shaft 16.

[0030] Therefore, in actual operation, when the carrier substrate 3 is slidably embedded into the housing 1, the lower contact plate 5 also enters the housing 1 simultaneously.

[0031] The device has a drive mechanism 4 disposed inside the support base plate 3, which establishes a reliable transmission connection with the lower contact plate 5. Multiple aluminum alloy plates 6 are disposed on the upper end of the lower contact plate 5. This design allows the lower contact plate 5 to rotate around the central axis of the positioning shaft 16 under the drive of the drive mechanism 4, while simultaneously driving the multiple aluminum alloy plates 6 to rotate inside the outer casing 1, ensuring uniform heating.

[0032] like Figure 1 , Figure 6 As shown, the drive mechanism 4 consists of a chain and its matching sprockets. One of the sprockets is connected to the drive motor via a key connection, while the drive motor is fixedly connected to the support base plate 3. In this configuration, by constraining the fixed connection between the other sprocket and the lower contact plate 5, the drive mechanism 4 can drive the lower contact plate 5 to rotate.

[0033] In practical applications, the sprocket fixedly connected to the lower contact plate 5 is usually located below the bearing, and the sprocket is firmly connected to the lower contact plate 5 by welding or other fixing methods.

[0034] It should be noted that in actual operation, during the initial stage, when the operator completes the installation of the aluminum alloy plate 6 and the lower contact plate 5, the carrier substrate 3 is often slid out of the outer shell 1. At this time, the outer shell 1 does not interfere with the operation, and the aluminum alloy plate 6 can be installed smoothly. However, after the installation of the aluminum alloy plate 6 and the carrier substrate 3 is completed, the aluminum alloy plate 6 and the carrier substrate 3 need to be slidably embedded into the outer shell 1. At this time, the cooperation between the carrier substrate 3 and the outer shell 1 can form a relatively sealed space. In this case, the presence of the heating mechanism 10 can quickly heat the aluminum alloy plate 6 to the expected temperature, and after the heating mechanism 10 is removed, the temperature drop process of the aluminum alloy plate 6 can meet the technical requirements of the annealing process.

[0035] In addition, such as Figure 2 , Figure 5 As shown, in the initial stage, in order to ensure that the aluminum alloy plate 6 remains vertical and that the state of the aluminum alloy plate 6 inside the outer shell 1 always meets expectations, this device is equipped with a clamping plate 7 on each of the left and right sides of the lower contact plate 5, and multiple positioning slide rails 14 are respectively set at the near ends of the two clamping plates 7.

[0036] Therefore, by constraining multiple aluminum alloy plates 6 to correspond one-to-one with multiple positioning slide rails 14, each aluminum alloy plate 6 is embedded in the corresponding positioning slide rail 14, and the positioning slide rail 14 can be used to limit the position of the aluminum alloy plate 6.

[0037] In addition, the two clamping plates 7 are slidably connected to the lower contact plate 5, and the two clamping plates 7 are jointly configured with a left and right displacement mechanism. This allows the distance between each clamping plate 7 and the lower contact plate 5 to be changed by the left and right displacement mechanism after the aluminum alloy plate 6 enters the housing 1. This avoids the positioning slide rail 14 from being in continuous contact with the aluminum alloy plate 6 during the heating process, which would cause uneven heating of the aluminum alloy plate 6 and affect the annealing effect.

[0038] like Figure 4 , Figure 5 As shown, each lower contact plate 5 is provided with a through groove 13, and a slide rod 15 is inserted into the left and right sides of each through groove 13. The two slide rods 15 in a single through groove 13 are fixedly connected to two clamping plates 7 respectively. In this way, the cooperation between the through groove 13 and the slide rod 15 realizes the sliding connection between the clamping plate 7 and the lower contact plate 5, so that the clamping plate 7 can move left and right linearly on the lower contact plate 5.

[0039] like Figure 5 As shown, specifically, the left-right displacement mechanism includes two symmetrically arranged follower blocks 18, with a driven plate 17 shared between them. The lower end of the driven plate 17 abuts against the follower blocks 18. At this time, by constraining the projection of each follower block 18 onto the vertical plane to be a right-angled triangle structure, one right-angled side of each follower block 18 is fixedly connected to the corresponding clamping plate 7, and the other right-angled side of each follower block 18 abuts against the lower contact plate 5. The inclined sides of the driven plate 17 and the follower blocks 18 abut against each other. When the driven plate 17 moves up and down, it works in conjunction with the through groove 13 to constrain the trajectory of the slide rod 15, ensuring that the driven plate 17 (i.e., the clamping plate 7) can only perform left-right linear movement.

[0040] In actual operation, after the contact plate and aluminum alloy plate 6 are fed into the outer shell 1, the two clamping plates 7 can be driven to move in opposite directions by pressing down the driven plate 17. At this time, the positioning slide rail 14 will separate from the aluminum alloy plate 6.

[0041] In addition, to ensure that the driven plate 17 moves along a specific trajectory and applies pressure evenly to the two follower blocks 18, the device is designed with a driven plate 17, which is sleeved on the outside of the positioning shaft 16 and slides in cooperation with the positioning shaft 16, so as to realize the vertical linear movement of the driven plate 17 along the positioning shaft 16.

[0042] like Figure 5As shown, the driven plate 17 can be considered as a sleeve section and a contact section, wherein the projection of the contact section on the vertical plane is a trapezoidal structure. At this time, by fitting the sleeve section onto the outside of the positioning shaft 16 and abutting the lower inclined side of the contact section against the inclined side of the follower block 18, a sliding connection between the driven plate 17 and the positioning shaft 16 can be achieved, and the technical effect of the two follower blocks 18 moving in opposite directions when the driven plate 17 moves downward can also be achieved.

[0043] Furthermore, to ensure ease of operation, this device ensures that the two clamping plates 7 automatically reset after the downward pressure on the driven plate 17 is removed. That is, in practice, before the aluminum alloy plate 6 enters the outer shell 1 from the outside and after the aluminum alloy plate 6 exits the outer shell 1, this device can ensure that the aluminum alloy plate 6 can be clamped and fixed by the positioning slide rail 14.

[0044] like Figure 5 As shown, tension springs 19 are provided near the ends of the two slide rods 15 within a single through slot 13. The two axial ends of the tension springs 19 are movably connected to the corresponding two slide rods 15. At this time, the tension springs 19 cause the two clamping plates 7 to have a relative movement tendency. It is worth noting that there are two tension springs 19, which are arranged symmetrically front and back, effectively preventing the clamping plates 7 from causing stroke conflict due to force on one side.

[0045] like Figure 3 , Figure 4 As shown, in actual operation, after the lower contact plate 5 and multiple aluminum alloy plates 6 are placed into the outer shell 1, the positioning slide rail 14 releases its clamping force on the aluminum alloy plates 6. At this time, the lower contact plate 5 provides the necessary upper support for the aluminum alloy plates 6. Therefore, this device has an upper contact plate 8 arranged on the upper side of the inner cavity of the outer shell 1. The downward pressure applied to the aluminum alloy plates 6 by the upper contact plate 8 ensures that the aluminum alloy plates 6 located inside the outer shell 1 are clamped by the upper and lower sides, thereby ensuring that they will not tilt inside the outer shell 1.

[0046] Furthermore, the device has multiple limiting grooves 12 near the upper contact plate 8 and the lower contact plate 5, with each aluminum alloy plate 6 corresponding to one of the limiting grooves 12. By constraining the upper and lower sides of the aluminum alloy plate 6 to be inserted into the corresponding limiting grooves 12, the limiting grooves 12 can be used to further fix the position of the aluminum alloy plate 6.

[0047] It is worth noting that in practical applications, the depth of the limiting groove 12 is extremely small. Its main purpose is to prevent the aluminum alloy plate 6 from experiencing insufficient constraint force due to the small contact point during rotation with the lower contact plate 5. The function of the limiting groove 12 is to increase the contact area between the aluminum alloy plate 6 and the upper contact plate 8 and the lower contact plate 5.

[0048] At this time, the upper contact plate 8 is rotatably connected to the outer casing 1 to ensure that the upper contact plate 8 will not prevent the aluminum alloy plate 6 from rotating with the lower contact plate 5.

[0049] Furthermore, this device ensures that when the support substrate 3 is located inside the housing 1, multiple aluminum alloy plates 6 are in contact with the lower end face of the upper contact plate 8. This ensures that the aluminum alloy plates 6 can be subjected to the downward pressure applied to them by the upper contact plate 8.

[0050] Therefore, a cylinder 2 is fixedly connected to the upper end of the outer shell 1. The movable end of the cylinder 2 is connected to the upper contact plate 8 through an elastic element. In this way, the height of the upper contact plate 8 can be adjusted by the cylinder 2, ensuring that there is no stroke interference between the upper contact plate 8 and the aluminum alloy plate 6 during the process of the aluminum alloy plate 6 entering and exiting the outer shell 1. At the same time, it can also ensure that the upper contact plate 8 is tightly abutted and fixed to the aluminum alloy plate 6 after it moves down.

[0051] Furthermore, an adjusting plate 9 is fixedly connected to the movable end of cylinder 2. This adjusting plate 9 is located inside the cavity of the outer casing 1, such as... Figure 3 As shown, the adjusting plate 9 and the upper contact plate 8 are elastically connected by a compression spring. This ensures that the upper contact plate 8 provides sufficient downward pressure to the aluminum alloy plate 6, while effectively avoiding stroke interference between the upper contact plate 8 and the aluminum alloy plate 6.

[0052] like Figure 3 As shown, it is worth noting that a contact shaft 11 is provided on the lower side of the upper contact plate 8, and the central axis of the contact shaft 11 coincides with the central axis of the positioning shaft 16. In this case, by constraining the contact shaft 11 to be fixedly connected to the adjusting plate 9, and by slidingly connecting the contact shaft 11 to the upper contact plate 8, in actual operation, when the upper contact plate 8 moves downwards and contacts the aluminum alloy plate 6, by adjusting the height of the contact shaft 11 and the driven plate 17, it can be ensured that the contact shaft 11 continuously presses the driven plate 17 downwards during the downward movement of the upper contact plate 8. At this time, the contact shaft 11 can provide the required downward pressure to the driven plate 17.

[0053] It is particularly important to note that the downward movement of the upper contact plate 8 and the reverse movement of the two clamping plates 7 ensure that the aluminum alloy plate 6 is continuously and properly constrained. That is, before the annealing process begins, the device uses the positioning slide rail 14 to fix the position of the aluminum alloy plate 6. Once the annealing process begins, the upper contact plate 8 moves downward, and the positioning slide rail 14 separates from the aluminum alloy plate 6. At this point, the aluminum alloy plate 6 is fixed by the clamping effect of the upper contact plate 8 and the lower contact plate 5, ensuring that the aluminum alloy plate 6 does not come into extensive contact with other components during the annealing process, thereby preventing uneven heating of the aluminum alloy plate 6.

[0054] Therefore, this device ensures that when the upper contact plate 8 contacts the aluminum alloy plate 6, the clamping plate 7 and the aluminum alloy plate 6 are not in the same vertical plane.

[0055] In the practical application of this utility model:

[0056] First, the operator removes the device from the outer casing 1 by sliding the support base plate 3.

[0057] Next, the operator embeds the aluminum alloy plate 6 to be processed into multiple positioning slide rails 14, during which the positioning slide rails 14 precisely fix the position of the aluminum alloy plate 6.

[0058] Subsequently, the operator slides the bearing base plate 3 in the opposite direction to allow it to re-enter the outer shell 1. During this process, the height of the lower end face of the upper contact plate 8 is greater than the height of the upper end face of the aluminum alloy plate 6.

[0059] Then, the operator controls the adjusting plate 9 to move downward through the cylinder 2. During this process, the contact shaft 11 continuously presses the driven plate 17 to move downward, and after the upper contact plate 8 contacts the aluminum alloy plate 6, the compression spring corresponding to the upper contact plate 8 continues to compress.

[0060] Finally, the operator activates the heating mechanism 10 and the drive mechanism 4, causing the aluminum alloy plate 6 to be rotated and heated within the outer casing 1.

[0061] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various adjustments, modifications, substitutions and variations can be made to these embodiments without departing from the basic principles and spirit of the present invention. The scope of protection of the present invention is defined by the appended claims and their equivalents.
