Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core heat treatment, in particular to a magnetic core high-efficiency air cooling device. Background Art

[0002] Iron-based amorphous and nanocrystalline soft magnetic materials have excellent soft magnetic properties such as high magnetic permeability, high saturation magnetic induction intensity, low loss, and low coercivity, and are widely used in the production of magnetic cores of electronic components. Iron-based amorphous and nanocrystalline materials themselves are rapidly cooled down by liquid alloy, so the material will produce stress due to structural imbalance. The magnetic properties of the material are very sensitive to stress. In order to give full play to the excellent soft magnetic properties of the material, the material must be wound into a magnetic core of corresponding specifications. After that, the internal stress of the material must be eliminated through heat treatment, and the crystalline structure must be appropriately changed to restore, improve and enhance the magnetic properties of the material.

[0003] Iron-based amorphous and nanocrystalline soft magnetic materials belong to an amorphous structure, which needs to be quickly cooled (air-cooled) after heat treatment to ensure its stable performance. If the temperature drops slowly, the internal amorphous structure will change, and the performance will change accordingly. However, in the air-cooling device of the prior art, the direction of the cooling air is always fixed. However, there are gaps between the laminations in the winding of the magnetic core. The cooling air of the prior art inevitably blows on the cross-section of the magnetic core, causing the solder joints of the magnetic core to fall off, resulting in loose pieces falling off, resulting in poor performance of the magnetic core and affecting the process yield.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0041] A magnetic core high efficiency air cooling device, such as Figure 1 , Figure 2 and Figure 8 As shown, including

[0042] An outer box body 1, a cooling cavity is arranged in the outer box body 1, a bell mouth 2 is arranged on one side wall of the outer box body 1, an inlet end of the bell mouth 2 is connected with the cooling cavity, and a magnetic core fragment storage mechanism 3 is arranged at an outlet end of the bell mouth 2;

[0043] The material door 4 is arranged on a side wall of the outer box body 1 close to the bell mouth 2;

[0044] and an electrical system control box 5, which is disposed on one side of the material door 4, and the electrical system control box 5 is connected to a cooling fan 6 and a magnetic core fragment storage mechanism 3;

[0045] A plurality of cooling fans 6 are disposed on the upper end of the outer box body 1 and the other two side walls of the outer box body 1 , and the panels of the outer box body 1 on which the cooling fans 6 are disposed are perpendicular to each other.

[0046] Specifically, the magnetic core to be cooled is sent into the cooling cavity through the material gate 4, and the electrical system control box 5 controls the cooling fan 6 to blow cold air to the outer surface 93 of the magnetic core, so as to achieve rapid air cooling to ensure the product performance. At the same time, the magnetic core fragment storage mechanism 3 can store the magnetic core fragments generated by air cooling in real time. Since the magnetic core to be cooled has a magnetic core cross-section 94 and a magnetic core outer surface 93, if the magnetic core cross-section 94 is blown for a long time during the actual cooling process, it is easy to cause the magnetic core solder joints to fall off, resulting in scattered pieces falling, causing the harm of poor magnetic core performance. The utility model arranges the cooling fan 6 on three mutually perpendicular panels of the outer box body 1, so as to meet the cooling work of the magnetic cores on the material racks of different shapes. The electrical system control box 5 is used to open the cooling fan 6 with the air outlet direction corresponding to the outer surface 93 of the magnetic core to blow cold air, so that the cooling wind direction can be kept always facing the outer surface 93 of the magnetic core, and the function of adjustable cooling wind size can be realized.

[0047] At the same time, the size can be adjusted.

[0048] In a preferred embodiment, Figure 3 , Figure 4 , Figure 5 As shown, the magnetic core fragment storage mechanism 3 includes:

[0049] The magnetic core fragments are stored in the inner box 33;

[0056] In a preferred embodiment, the discharge port 35 has a trumpet-shaped structure.

[0057] In a preferred embodiment, the magnetic core fragment storage mechanism 3 further includes:

[0058] The outer box body 37 for storing magnetic core fragments is arranged outside the inner box body 33 for storing magnetic core fragments. The rear side of the inner box body 33 for storing magnetic core fragments is connected to the inside of the outer box body 37 for storing magnetic core fragments. The front side of the outer box body 37 for storing magnetic core fragments is detachably connected to the front fixing plate 32.

[0059] The first filtering device 8 is disposed at the rear side of the outer box 37 for storing the magnetic core fragments.

[0061] In a preferred embodiment, the first filter device 8 includes an exhaust plate 38 and a filter plate 39 which are stacked. Bolt fixing holes are provided at the edges of the exhaust plate 38 and the filter plate 39 and are connected by a bolt assembly 81. The exhaust plate 38 has an exhaust hole 381, and the filter plate 39 has a mesh-shaped filter hole 391. Specifically, the heat generated by the cooling operation is discharged to the outside through the exhaust hole 381; the filter hole 391 is used to discharge the heat and filter out the magnetic core fragments generated by the cooling operation.

[0062] Specifically, the magnetic core fragment suction port 31 is fixed to the bell mouth 2 with screws, and the hot air and magnetic core fragment mixture are collected in the storage bin 333 under the suction force of the suction motor 334. Under the action of gravity, the magnetic core fragments fall from the discharge port 35 to the outer box discharge pipe 372 for discharge, and a storage bag can be installed on the outer box discharge pipe 372 for storage;

[0063] At the same time, the hot air is driven by the rotation of the exhaust motor 36 to pass through the first filter 331 and the second filter 332, and then through the rear side of the magnetic core fragment storage inner box 33 and filtered by the exhaust plate 38 and the filter plate 39 before being discharged out of the device. Preferably, a double-layer first filter 331 and a second filter 332 are set to filter to ensure that the magnetic core fragments are not taken out when the hot air is discharged;

[0064] The outer box exhaust motor mounting port 371 is used to position and fix the exhaust motor 36. The front fixing plate 32 is fixed to the air suction side of the magnetic core fragment storage inner box 33 with screws. The exhaust plate 38 and the filter plate 39 are stacked and aligned and fixed to the exhaust side of the magnetic core fragment storage outer box 37 with bolts so that the debris storage and exhaust device forms a complete cavity that can filter debris, ensuring that the magnetic core fragments will not splash out of the cooling device during air cooling operation, thereby ensuring production safety.

[0065] Preferably, the magnetic core fragment storage mechanism 3 adopts a segmented design, and the components are positioned and fixed to each other with screws, which is convenient for disassembly, maintenance and fault repair, and is very convenient to use and maintain.

[0066] In a preferred embodiment, a second filtering device 7 having the same structure as the first filtering device 8 is provided on the side wall of the outer box body 1 above the material door 4 .

[0067] Specifically, the first filter device 8 and the second filter device 7 contained in the utility model have the functions of exhausting, heat dissipating and filtering at the same time, so as to dissipate the heat generated by the air cooling of the magnetic core into the air, and at the same time filter out the magnetic core fragments generated by the air cooling, so that the fragments will not splash in the air with the exhaust, causing production safety hazards.

[0068] Specifically, the heat in the cooling cavity can be extracted in real time through the first filter device 8 and the second filter device 7, and the cooling time can be controlled to ensure product performance;

[0069] At the same time, the magnetic core fragment storage mechanism 3, the first filter device 8 and the second filter device 7 ensure that the cooling process is safe and reliable, and the production site is clean and tidy;

[0070] In a preferred embodiment, the air outlet of the cooling fan 6 is perpendicular to the panel of the outer box 1 where the cooling fan 6 is located. The cooling fan 6 includes a top fan that can blow cold air in a first direction, a first side fan that can blow cold air in a second direction, and a second side fan that can blow cold air in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0071] Specifically, Figure 6 , Figure 7 , Figure 8As shown, the utility model is provided with cooling fans 6 on three sides to meet the cooling of different material racks filled with magnetic cores used in different forms of heat treatment furnaces. When the cooling wind blows on the outer surface 93 of the magnetic core, it is prevented that the cooling wind blows on the cross section 94 of the magnetic core and causes the magnetic core to be scattered. The material rack includes a vertical material rack 91 and a horizontal material rack 92. There are gaps between the layers in the winding and forming of the magnetic core. The cooling wind blows on the cross section 94 of the magnetic core for a long time, which will cause the magnetic core solder joints to fall off, resulting in scattered pieces falling, causing poor performance of the magnetic core and affecting the process yield and production. The cooling fans 6 on the three sides are controlled separately. According to the different forms of the magnetic core material racks, only the fan corresponding to the direction of the outer surface 93 of the magnetic core needs to be turned on during the cooling operation. The cooling fan in the required cooling wind direction is turned on at the same time each time to achieve fast and efficient cooling of the magnetic core.

[0072] Specifically, the wind force and wind direction of the cooling fan 6 in each direction of the utility model can be individually adjusted to ensure that the cooling wind direction always blows toward the outer surface 93 of the magnetic core, thereby reducing the risk of magnetic core fragments.

[0073] In a preferred embodiment, the cooling fans 6 are evenly arranged in an array on the outer box 1, and the air outlets of the cooling fans 6 are arranged in the cooling cavity.

[0074] In a preferred embodiment, the electrical system control box 5 is provided with a plurality of buttons corresponding to the cooling fans 6 .

[0075] The working process of the utility model is as follows:

[0076] 1. Open the material door 4, move the heat-treated magnetic core rack into the cooling chamber and then close the material door;

[0077] 2. According to the rack form (vertical or horizontal), the top fan, the first side fan or the second side fan of the equipment is turned on through the corresponding button on the electrical system control box 5 to perform air cooling of the magnetic core, so as to achieve the purpose of rapid cooling of the magnetic core;

[0078] 3. The magnetic core fragment storage mechanism 3 is started synchronously to store the fragments and discharge the heat inside the device through the filter ports at the upper part and the left side of the device inlet;

[0079] 4. After the cooling operation is completed, turn off the cooling fan 6, open the material door 4 and take out the material rack.

[0080] In summary, the magnetic core high-efficiency air cooling device provided by the utility model is safe and reliable in operation, can rapidly cool to ensure product performance, and can collect magnetic core fragments generated by air cooling in real time and keep the cooling wind direction always toward the outer surface 93 of the magnetic core, and the wind speed is adjustable and the wind direction is controllable. It meets the mass production needs, greatly improves the production efficiency and product quality, and keeps the work site clean and tidy, meeting the lean production requirements and on-site 5S control standards.
