Description

Technical Field

[0001] The utility model relates to the field of transverse magnetic heat treatment of soft magnetic materials, in particular to a magnetic core material disc rack. Background Art

[0002] A magnetic core is a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has the characteristics of low loss. During the production process of the magnetic core, some debris and debris will adhere to the surface, affecting the performance of the magnetic core. At this stage, a magnetic core impurity removal device is generally used to remove impurities from the magnetic core, that is, corn starch and the magnetic core are mixed and vibrated, and then the impurity-free magnetic core is obtained.

[0003] At present, in the process of magnetizing the magnetic core, the magnetic core is usually strung on a stainless steel tube, stacked together and put into an oven. After demagnetization and cooling, the two poles of the magnet are respectively placed close to the two poles of a stronger magnet and kept for a certain period of time, or the magnet is wrapped around a stronger magnet, rotated repeatedly and kept for a certain period of time, so that the magnetism of the magnet can be restored or enhanced.

[0004] However, the method of stacking the magnetic cores on the stainless steel tube is not convenient for heat dissipation. For magnetic cores with an outer diameter exceeding 100 mm, stringing them together can easily cause the magnetic cores to be compressed and deformed and affect the performance of the magnetic cores. Utility Model Content

[0009] Wherein, a plurality of groups of the material tray assemblies are arranged along the length direction of the clamping rod, the bottom plate and the material blocking edge are arranged between the clamping rod, and a plurality of heat dissipation holes are arranged on the bottom plate.

[0028] See also Figure 1-Figure 4, which is a schematic structural diagram of a magnetic core material tray frame provided in an embodiment of the utility model, the magnetic core material tray frame comprises a base support 100 and a tray assembly 200 arranged on the base support 100, wherein:

[0029] In order to avoid the magnetic core from being deformed by pressure and not affecting its performance, a tray assembly 200 is used instead of stringing the magnetic core on the stainless steel tube. The tray assembly 200 includes a base 210 and a retaining edge 220 arranged on the periphery of the base 210. The retaining edge 220 is vertically arranged on the end face of the base 210 to prevent the magnetic core laid on the base 210 from sliding off.

[0030] In order to facilitate heat transfer and heat dissipation of the magnetic core during the magnetic heating process, heat dissipation holes 212 are provided on the bottom plate 210, and the heat dissipation holes 212 are distributed all over the end surface of the bottom plate 210. Since multiple groups of tray assemblies 200 can be arranged along the length direction of the base bracket 100, when the bottom plate 210 is heated, the bottom plate 210 transfers heat upward through the heat dissipation holes 212 on each tray assembly 200, thereby realizing heat reuse and improving heating efficiency. In order to facilitate adding a magnetic core into the tray assembly 200, a placement space for taking and placing the magnetic core is reserved between adjacent tray assemblies 200.

[0031] During the heating process, the magnetic core can be laid on the end surface of the chassis 210, replacing the traditional stacking method, avoiding the deformation of the bottom magnetic core due to pressure, and the effect is better for the magnetic core with an outer diameter exceeding 100 mm.

[0032] Furthermore, in order to facilitate the clamping on the base bracket 100, the outer periphery of the chassis 210 is divided into three equal parts, and the circular concave portion 211 is formed toward the chassis 210, while the retaining edge 220 vertically arranged on the outer periphery of the chassis 210 is divided into three equal parts, and the circular concave portion 221 is formed toward the chassis 210. For the purpose of being embedded in the base bracket 100, the first clamping portion 211 and the second clamping portion 221 are equal in size and corresponding in position, and the curvature of the first clamping portion 211 and the second clamping portion 221 is configured to be contoured with the chassis 210 bracket, so that the material tray assembly 200 is just embedded in the chassis 210 bracket.

[0033] Furthermore, in order to embed the material tray assembly 200 in the base bracket 100, the base bracket 100 includes a hook 110, at least three clamping rods 120, and a connecting rod 130 connecting the clamping rods 120 and the hook 110. For the purpose of structural stability and enhancing the clamping effect, the clamping rods 120 in this embodiment are in a triangular shape, which are respectively used to correspond to the first clamping portion 211 on the chassis 210 and the second clamping portion 221 on the retaining edge 220. At the same time, since the size of the clamping rod 120 is configured to be similar to the size of the first clamping portion 211 and the second clamping portion 221, when the clamping rod 120 is embedded in the first clamping portion 211 and the second clamping portion 221, the material tray assembly 200 can be clamped by the clamping rod 120 at the center of the base bracket 100.

[0034] It is worth noting that the number of the above-mentioned clamping rods 120 includes but is not limited to three, and increasing the number of clamping rods 120 will increase the clamping force for the tray assembly 200. For the structural stability of the base bracket 100, a connecting rod 130 is provided on any clamping rod 120, and the two ends of the connecting rod 130 are respectively used to connect the clamping rod 120 and the hook 110, and the connection can be welded to form a triangular base bracket 100. For the purpose of facilitating heating and taking and placing, the hook 110 includes a bent portion 111 and a connecting portion 112, the bent portion 111 is used to be hung on the heating device, and the connecting portion 112 is used to be welded with one end of the connecting rod 130 away from the clamping rod 120, so as to hang the tray assembly 200 on the heating device for heating.

[0035] In summary, according to a magnetic core material tray rack proposed by the utility model, by providing a chassis with heat dissipation holes and placing the magnetic core on the chassis, air convection can be achieved during the magnetic heating of the magnetic core, which is more convenient for heat transfer and heat dissipation, and there is no need to stack the magnetic cores, thereby reducing the possibility of compression and deformation of the magnetic cores. At the same time, the material tray assembly can be placed between the clamping rods, which is convenient for disassembly and assembly. Specifically, the magnetic core material tray rack includes a base bracket and a material tray assembly arranged on the base bracket. The base bracket includes a hook, at least three clamping rods, and a connecting rod connecting the clamping rods and the hooks. The clamping rods are used to clamp the material tray assembly, and the three clamping rods can stably support the material tray assembly.
