Technical Field
[0001] This utility model relates to the field of nanocrystalline alloy magnetic core processing technology, and in particular to a secondary annealing treatment device for nanocrystalline alloy magnetic cores. Background Technology
[0002] In the manufacturing process of nanocrystalline alloy magnetic cores, secondary annealing is a crucial step, as it can improve the magnetic properties and microstructure of the core.
[0003] In the traditional secondary annealing process of magnetic cores, in order to ensure that the magnetic core does not shift or wobble during annealing and to ensure the consistency of magnetic core annealing, the magnetic core is usually fixed on a convex fixing plate. However, due to the difference in the size of the magnetic core, when it is necessary to replace the convex fixing plate that is suitable for magnetic cores of different sizes, it is often necessary to disassemble the screws. This operation method is not only cumbersome, but also consumes a lot of time, which greatly reduces production efficiency and is not conducive to the efficient production of nanocrystalline alloy magnetic cores.
[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In the process of secondary annealing of traditional magnetic cores, in order to ensure that the magnetic cores do not shift or shake during annealing and to ensure the consistency of magnetic core annealing, they are usually fixed on a convex fixing plate. However, the sizes of magnetic cores are different, and when replacing the convex fixing plate, the screws must be disassembled, which is cumbersome and time-consuming, thereby reducing production efficiency. Therefore, in order to address the above problems, a secondary annealing treatment device for nanocrystalline alloy magnetic cores is proposed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where, during the secondary annealing process of traditional magnetic cores, in order to ensure that the magnetic cores do not shift or shake during annealing and to guarantee the consistency of the annealing, they are usually fixed on a convex fixing plate. However, since the magnetic cores are of different sizes, the screws must be disassembled when replacing the convex fixing plate, which is cumbersome, time-consuming, and reduces production efficiency. Therefore, this invention proposes a secondary annealing equipment for nanocrystalline alloy magnetic cores.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a secondary annealing treatment device for nanocrystalline alloy magnetic cores, comprising an annealing electrical box, a door rotatably connected to the surface of the annealing electrical box, a replacement device provided on the inner surface of the annealing electrical box, the replacement device comprising two mounting plates, both mounting plates being fixedly connected to the inner surface of the annealing electrical box, both mounting plates having a sliding groove on their surface, a sliding plate slidably connected to the inner wall of the sliding groove, a sliding rod slidably inserted into the surface of the mounting plate, a slot being provided on the surface of the sliding plate, a round block being fixedly connected to one end of the sliding rod, and a convex fixing plate being fixedly connected to the surface of the sliding plate.
[0007] The effect achieved by the above-mentioned components is as follows: by setting up a replacement device, the convex fixing plate can be replaced. This avoids the situation where, during the secondary annealing process of traditional magnetic cores, in order to ensure that the magnetic cores do not shift or shake during annealing and to ensure the consistency of the annealing, they are usually fixed on a convex fixing plate. However, since the magnetic cores are of different sizes, when replacing the convex fixing plate, the screws must be disassembled, which is cumbersome and time-consuming, thus reducing production efficiency.
[0008] Preferably, springs are fitted onto the arc surfaces of the two sliding rods, and the two ends of the springs are fixedly connected to the mounting plate and the circular block, respectively.
[0009] The effect achieved by the above components is that, through the cooperation of the spring mounting plate and the round block, due to the elastic force of the spring itself, after pulling the round block and releasing it, the sliding rod will automatically return to the original position, which can also prevent the sliding rod from being lost.

[0015] The effect achieved by the above-mentioned components is as follows: by setting up a fixing device, the door of the box can be fixed by the staff, which avoids the problem that the traditional box door cannot be fixed after being opened when the staff needs to replace or repair the inside of the annealing electrical box, and may close by itself, which makes it inconvenient for the staff to repair the inside of the annealing electrical box, and may also cause the maintenance personnel to be bumped or injured. This improves the practicality of the device.
[0016] Preferably, the surface of the sliding block is provided with a fixing groove, and the surface of the placement compartment is slidably inserted with a sliding rod, the size of the fixing groove being adapted to the size of the sliding rod.
[0017] The effect achieved by the above components is that, through the cooperation of the sliding rod and the fixing groove, the user can prevent the box from being fixed after opening the box when maintenance is not required and when the box door is opened.
[0018] Preferably, a limiting groove is formed on the surface of the sliding block, and the size of the limiting groove is adapted to the size of the sliding rod.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a secondary annealing treatment device for nanocrystalline alloy magnetic cores, including an annealing electrical box 1. A door 2 is rotatably connected to the surface of the annealing electrical box 1. A replacement device 3 is provided on the inner surface of the annealing electrical box 1. By setting the replacement device 3, the convex fixing plate 36 can be replaced. This avoids the problem that, in traditional secondary annealing processes, to ensure the magnetic core does not shift or shake during annealing and to guarantee consistent annealing, it is usually fixed to the convex fixing plate 36. However, the magnetic cores are of varying sizes. When replacing the convex fixing plate 36, the screws need to be removed, which is cumbersome and time-consuming, thus reducing production efficiency. The inner surface of the annealing electrical box 1 is equipped with a fixing device 4. By setting the fixing device 4, the staff can fix the box door 2. This avoids the problem that when the staff needs to replace or repair the inside of the annealing electrical box 1, the traditional box door 2 cannot be fixed after being opened and may close by itself, which makes it inconvenient for the staff to repair the inside of the annealing electrical box 1 and may also cause the repair personnel to be bumped. This improves the practicality of the device.
[0030] The specific setup and function of the replacement device 3 and the fixing device 4 will be explained in detail below.
[0031] Reference Figure 2 and Figure 3As shown in this embodiment: the replacement device 3 includes two mounting plates 31, both of which are fixedly connected to the inner surface of the annealing electrical box 1. Each mounting plate 31 has a groove 32 on its surface, and a sliding plate 33 is slidably connected to the inner wall of the groove 32. A sliding rod 34 is slidably inserted into the surface of the mounting plate 31. A slot is formed on the surface of the sliding plate 33, and a round block 35 is fixedly connected to one end of the sliding rod 34. A convex fixing plate 36 is fixedly connected to the surface of the sliding plate 33. Springs 37 are fitted onto the arc surfaces of the two sliding rods 34, and both ends of the springs 37 are fixedly connected to the mounting plate 31 and the round block 35, respectively. An L-shaped plate 38 is fixedly connected to the surface of each mounting plate 31. The size of the L-shaped plate 38 is related to the sliding rod 34. The size of the movable plate 33 is adapted to the dimensions of the two L-shaped plates 38. Several hemispherical balls 39 are fixedly connected to the surfaces of the two L-shaped plates 38. The size of the slot of the sliding plate 33 is adapted to the size of the sliding rod 34. Through the cooperation of the spring 37, the mounting plate 31 and the round block 35, due to the elasticity of the spring 37 itself, after pulling the round block 35 and releasing it, the sliding rod 34 will automatically return to the origin. This can also prevent the sliding rod 34 from being lost. Through the cooperation of the L-shaped plate 38 and the mounting plate 31, the sliding plate 33 can be easily and quickly positioned at the opening of the groove 32. Through the cooperation of the hemispherical balls 39, the L-shaped plate 38 and the sliding plate 33, the operator can easily pull out the sliding plate 33, reducing the friction between the sliding plate 33 and the L-shaped plate 38, and the sliding plate 33 can be pulled out quickly.
[0032] Reference Figure 4 and Figure 5 As shown, specifically, the fixing device 4 includes a hollow plate 41, which is fixedly connected to the inner surface of the annealing electrical box 1. A placement compartment 42 is fixedly connected to the surface of the box door 2. A sliding block 43 is slidably connected to the inner surface of the placement compartment 42. A moving hole is opened on the surface of the placement compartment 42. An elliptical block 44 is slidably connected to the inner wall of the moving hole of the placement compartment 42. One end of the elliptical block 44 is fixedly connected to the surface of the sliding block 43. A fixing groove 45 is opened on the surface of the sliding block 43. A sliding rod 46 is slidably inserted into the surface of the placement compartment 42. The size of the fixing groove 45 is adapted to the size of the sliding rod 46. A limiting groove 47 is opened on the surface of the sliding block 43. The size of the limiting groove 47 is adapted to the size of the sliding rod 46. Through the cooperation of the sliding rod 46 and the fixing groove 45, when the user does not need to maintain the box and opens the box door 2, it can prevent the box door 2 from being fixed after opening. Through the cooperation of the sliding rod 46 and the limiting groove 47, when the user needs to maintain the box and opens the box door 2, it can prevent the sliding block 43 from moving during maintenance.
[0033] When the worker needs to replace the convex fixing plate 36, the worker pulls the two round blocks 35, which drive the sliding rod 34. The sliding rod 34 slides within the slot of the sliding plate 33. When the sliding rod 34 moves away from the slot of the sliding plate 33, the worker pulls out the convex fixing plate 36. The convex fixing plate 36 drives the two sliding plates 33 to slide within the sliding groove 32. After it is fully pulled out, the worker replaces the other convex fixing plate 36, places the sliding plate 33 on the surface of the L-shaped plate 38, and pushes it into the sliding groove 32. The sliding plate 33 slides against the arc surface of the hemisphere 39. After being fully pushed in, the sliding rod 34 automatically engages with the slot of the sliding plate 33 due to the elasticity of the spring 37, thus completing the replacement. By setting the replacement device 3, the convex fixing plate 36 can be replaced. This avoids the situation where, during the secondary annealing process of traditional magnetic cores, in order to ensure that the magnetic cores do not shift or shake during annealing and to ensure the consistency of the annealing, they are usually fixed on the convex fixing plate 36. However, since the magnetic cores are of different sizes, the screws must be disassembled when replacing the convex fixing plate 36, which is cumbersome and time-consuming, thus reducing production efficiency.
[0034] When the user needs to open the fixing device 4, the operator opens the box door 2 to 90 degrees, and pulls out the sliding rod 46 on the surface of the placement compartment 42. The sliding rod 46 slides in the fixing groove 45 until it is fully pulled out. The operator pushes the elliptical block 44, which drives the sliding block 43 to move. The sliding block 43 moves into the hollow plate 41, and the sliding rod 46 is engaged in the limiting groove 47, thus completing the fixing. By setting the fixing device 4, the operator can fix the box door 2, avoiding the inconvenience caused by the traditional box door 2 not being able to be fixed after opening when the operator needs to replace or repair the annealing electrical box 1, and the possibility of the door closing by itself. This also improves the practicality of the device.
