Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of nanocrystalline magnetic cores, in particular to a material rack structure used for heat treatment of nanocrystalline magnetic cores. Background Art

[0002] Nanocrystalline magnetic cores are a new type of magnetic material composed of multiple metals that meet the requirements of efficient energy utilization. Heat treatment of nanocrystalline cores is a critical manufacturing step. This special treatment method, under high temperature and high pressure, forms a nanocrystalline structure on the surface of the core material. This heat treatment transforms the internal crystalline structure of the nanocrystalline material, forming irregularly distributed grains with diameters of 10 to 20 nanometers, thereby acquiring the properties of a soft magnetic material.

[0003] Patent document No. 202322616920.3 discloses a material rack for heat treatment of nanocrystalline magnetic cores, including a base component and a first material rod. The base component includes at least two flanges. Two adjacent flanges are assembled with spacers to form an interval cavity for the flow of atmosphere, and convection heat transfer is carried out by using air guide holes opened on the flanges, thereby avoiding the problem of large temperature difference between the upper and lower parts of the magnetic core on the first material rod due to overheating of the flanges.

[0004] However, in traditional rack structures used for heat treatment of nanocrystalline magnetic cores, in order to facilitate the loading of magnetic cores, most of them adopt a bottom-fixed method, while the top of the rack is open. During the lifting process, the rack loaded with many magnetic cores is unstable, which may cause damage to the magnetic cores during the annealing furnace.

[0005] For example, a shaking rod may cause the loaded magnetic cores to collide with the wall of the annealing furnace, and the shaking may also cause the magnetic cores to collide and shake with each other. Utility Model Content

[0006] The utility model discloses a material rack structure for heat treatment of nanocrystalline magnetic cores, aiming to solve the technical problem that in traditional material rack structures for heat treatment of nanocrystalline magnetic cores, in order to facilitate the loading of magnetic cores, most of them adopt a bottom-fixed method while the top of the material rack is in an open state. During the lifting process, the material rod loaded with a large number of magnetic cores is unstable, which may cause damage to the magnetic cores during the process of being placed in an annealing furnace.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A material rack structure for heat treatment of nanocrystalline magnetic cores, comprising a base plate and a fixing rod fixed to the base plate, a connecting plate being provided on the outer wall of the fixing rod near the top, and further comprising: an adjusting mechanism: the adjusting mechanism is arranged on the base plate and the connecting plate; a limiting locking mechanism: the limiting locking mechanism comprises a connecting block arranged on the adjusting mechanism, a material rod is installed on the top outer wall of the connecting block, an adapting hole is provided at the top of the material rod, a magnetic core body distributed at equal distances is sleeved on the outer wall of the material rod, sliding holes distributed at equal distances are provided on the connecting plate, a first slider is slidably connected to the inner wall of the sliding hole, a socket is opened on the top of the first slider, a notch is provided on one side outer wall of the first slider, the socket is communicated with the inside of the notch, and the same plug is inserted into the socket and the inner wall of the adapting hole.

[0009] In this solution, the limiting locking mechanism can flexibly control the locking of the top end of the material rod. When the plug is removed, the top end of the material rod will be detached from the notch of the first slider, and then the magnetic core body that needs heat treatment can be loaded onto the outer wall of the material rod. The loaded material rod can be inserted into the notch again and finally locked with the plug, thereby achieving stable fixation of the first two ends of the material rod and avoiding shaking of the magnetic core body during the heat treatment process.

[0010] In a preferred embodiment, the adjustment mechanism includes mounting grooves equidistantly distributed on the top of the base plate, a second slider is slidably mounted on the inner wall of the mounting groove, and the outer wall of one side of the first slider and the second slider is connected to the same connecting rod.

[0011] The adjustment mechanism provided can adjust the movement of the first slider and the second slider synchronously up and down. When heat treating magnetic core bodies of different sizes, the connecting rod can be used to adjust the distance between the first slider and the second slider and the fixed rod, so that the magnetic core body loaded onto the material rod can be stably located between the fixed rod and the edge of the material rack, so that the magnetic core body on the material rack can be more evenly heat treated.

[0012] In a preferred embodiment, a through hole is provided inside the fixing rod, and air holes are distributed at equal distances on the outer wall of the fixing rod, the air holes are communicated with the through hole, and the air holes located on the outer wall of the fixing rod correspond to the material rods distributed at equal distances, and a guide bucket is provided at the bottom end of the fixing rod, and the guide bucket is communicated with the inside of the fixing rod.

[0013] The guide hopper can guide the heat from the bottom of the base plate into the fixed rod, and finally heat the core body from the inside of the material rack through the air holes outside the fixed rod. In this process, since the air holes are relative to the material rod, the heat rising from the inside can heat the core body more specifically.

[0014] As can be seen from the above, a material rack structure for heat treatment of nanocrystalline magnetic cores includes a base plate and a fixing rod fixed to the base plate, a connecting plate is provided on the outer wall of the fixing rod near the top, and further includes: an adjustment mechanism: the adjustment mechanism is arranged on the base plate and the connecting plate; a limit locking mechanism: the limit locking mechanism includes a connecting block arranged on the adjustment mechanism, a material rod is installed on the top outer wall of the connecting block, an adapting hole is provided at the top of the material rod, a magnetic core body equidistantly distributed is sleeved on the outer wall of the material rod, the connecting plate is provided with sliding holes equidistantly distributed, a first slider is slidably connected to the inner wall of the sliding hole, a socket is opened at the top of the first slider, a notch is provided on one side outer wall of the first slider, the socket is communicated with the inside of the notch, and the socket and the inner wall of the adapting hole are plugged with the same plug. The material rack structure for heat treatment of nanocrystalline magnetic cores provided by the utility model has the technical effect of improving the stability of heat treatment of the magnetic core body and targeting.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0021] The utility model discloses a material rack structure for heat treatment of nanocrystalline magnetic cores, which is mainly applied to traditional material rack structures for heat treatment of nanocrystalline magnetic cores. When in use, in order to facilitate the loading of magnetic cores, most of them adopt a bottom-fixed method, and the top of the material rack is in an open state. During the lifting process, the material rod loaded with a large number of magnetic cores is unstable, which may cause damage to the magnetic cores during the process of being placed in the annealing furnace.

[0022] Reference Figure 1 、 Figure 2 and Figure 3 , a material rack structure for heat treatment of nanocrystalline magnetic cores, including a base plate 1 and a fixing rod 2 fixed on the base plate 1, a connecting plate 3 is provided on the outer wall of the fixing rod 2 near the top, and also includes: an adjusting mechanism: the adjusting mechanism is arranged on the base plate 1 and the connecting plate 3; a limit locking mechanism: the limit locking mechanism includes a connecting block 13 arranged on the adjusting mechanism, a material rod 6 is installed on the top outer wall of the connecting block 13, the top of the material rod 6 is provided with an adapting hole, the outer wall of the material rod 6 is sleeved with an equidistantly distributed magnetic core body 7, the connecting plate 3 is provided with equidistantly distributed sliding holes, a first slider 9 is slidably connected to the inner wall of the sliding hole, a socket is opened on the top of the first slider 9, a notch 11 is provided on one side outer wall of the first slider 9, the socket is communicated with the inside of the notch 11, and the same plug 10 is plugged into the inner wall of the socket and the adapting hole.

[0023] The diameters of the jack and the adapter hole are consistent.

[0024] Among them, a baffle 15 is provided on the outer wall of the material rod 6 near the bottom, and leakage holes are opened on the baffle 15 at equal distances. The bottom layer of the magnetic core body 7 of the material rod 6 is directly in contact with the baffle 15. The setting of the leakage holes can make the magnetic core body 7 more effectively heated.

[0025] Specifically, the limit locking mechanism set up can flexibly control the locking of the top end of the material rod 6. When the plug 10 is removed, the top end of the material rod 6 will be detached from the notch 11 of the first slider 9, and then the magnetic core body 7 that needs heat treatment can be loaded onto the outer wall of the material rod 6. The loaded material rod 6 can be inserted into the notch 11 again, and finally locked with the plug 10, thereby achieving stable fixation of the first two ends of the material rod 6 and avoiding shaking of the magnetic core body 7 during the heat treatment process.

[0026] Reference Figure 1 and Figure 3 In a preferred embodiment, the adjustment mechanism includes mounting grooves equidistantly distributed on the top of the base plate 1, and a second slider 12 is slidably installed on the inner wall of the mounting groove. The outer wall of one side of the first slider 9 and the second slider 12 is connected to the same connecting rod 8.

[0027] Specifically, the adjustment mechanism provided can synchronously adjust the movement of the first slider 9 and the second slider 12 up and down. When heat treating magnetic core bodies 7 of different sizes, the connecting rod 8 can be used to adjust the distance between the first slider 9 and the second slider 12 and the fixed rod 2, so that the magnetic core body 7 loaded onto the material rod 6 can be stably located between the fixed rod 2 and the edge of the material rack, so that the magnetic core body 7 on the material rack can be more evenly heat treated.

[0028] Reference Figure 3 In a preferred embodiment, a limit stopper 14 is provided on one side outer wall of the second slider 12, and an inclined surface is provided on the side of the limit stopper 14 close to the connecting block 13, and the connecting block 13 and the inclined surface are used in conjunction with each other.

[0029] During actual use, the lock at the top of the material rod 6 needs to be unlocked before loading. During the tilting of the material rod 6, the connecting block 13 connecting the material rod 6 can be against the inclined surface of the limit block 14, preventing the material rod 6 from falling completely while facilitating loading.

[0030] Reference Figure 1 、 Figure 2 and Figure 4 In a preferred embodiment, a through hole is provided inside the fixed rod 2, and air holes are distributed at equal distances on the outer wall of the fixed rod 2. The air holes are connected to the through holes, and the air holes located on the outer wall of the fixed rod 2 correspond to the material rods 6 distributed at equal distances. A guide bucket 16 is provided at the bottom end of the fixed rod 2, and the guide bucket 16 is connected to the interior of the fixed rod 2.

[0031] Specifically, through the provided guide bucket 16, the heat at the bottom of the base plate 1 can be guided into the fixed rod 2, and finally the magnetic core body 7 can be heated from the inside of the material rack through the air holes outside the fixed rod 2. In this process, since the air holes are relative to the material rod 6, the heat rising from the inside can more specifically heat treat the magnetic core body 7.

[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, support pads 5 are equidistantly distributed on the bottom outer wall of the base plate 1, and a pull ring 4 is provided on the top of the fixing rod 2. The pull ring 4 can be hung using a lifting device, so that the entire material rack can be placed in the annealing furnace required for heat treatment.

[0033] Working principle: When in use, first release the restriction on the top end of the material rod 6. After the restriction is released, the top end of the material rod 6 will be detached from the notch 11 on the side of the first slider 9. Then, under the action of the limit block 14, the material rod 6 remains in an inclined state. At this time, the magnetic core body 7 can be loaded onto the material rod 6, and then the top end of the loaded material rod 6 is inserted into the notch 11. The plug 10 is inserted into the corresponding jack and adapter hole to limit it. Then, the loaded material rack is placed in the annealing furnace through the lifting tool to complete the heat treatment.

[0034] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
