Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core sintering, in particular to a manganese-zinc ferrite magnetic core sintering device. Background Art

[0002] Magnetic materials are often needed in some electronic components, such as magnetic strips and rods used in induction electric heating equipment. The magnetic materials contain manganese-zinc ferrite. In order to complete the synthesis and crystallization process of the precursor and achieve a certain density and hardness to meet application requirements, a sintering device is required to sinter the manganese-zinc ferrite core. In addition, material migration and flow will occur during the sintering process, which will reduce the porosity inside the material and increase the density and hardness, thereby improving the mechanical and electrical properties of the material.

[0003] Chinese patent application number: CN202221932288.2 discloses a manganese-zinc ferrite core uniform heat sintering device, including an installation box and a sintering box, the installation box and the sintering box are respectively provided with a box door and a door body, a heating mechanism and a rotating rod are provided in the sintering box, the bottom end of the rotating rod passes through the sintering box and is connected to a rotating drive mechanism arranged in the installation box, a plurality of mounting seats are provided on the rotating rod, a placing rod is provided on the mounting seat, and a plurality of spacer rods are provided on the placing rod; the device places the manganese-zinc ferrite core on the placing rod in a suspended manner, and causes it to rotate inside the sintering box during the sintering process, thereby ensuring that the manganese-zinc ferrite core is evenly heated and improving the sintering quality.

[0004] From the above, it can be known that in the prior art, the magnetic core is suspended and caused to rotate so that the magnetic core is evenly sintered. However, since the heating tubes of some sintering devices are installed on the upper side or lower side of the sintering furnace, it is not convenient to change the heating surface of the magnetic core simply by rotating. If the heating tubes are installed on the upper side of the sintering furnace, it is not convenient to sinter the bottom of the magnetic core by rotating the magnetic core, which makes the uniform sintering efficiency of the magnetic core low. At the same time, the magnetic core needs to be cooled after sintering. The existing cooling method is to cool it in the original sintering furnace, which will reduce the temperature in the sintering furnace. When the next batch of magnetic cores are sintered, the sintering furnace needs to be preheated again, which prolongs the sintering time. Utility Model Content

DETAILED DESCRIPTION

[0030] In the prior art, the magnetic core is suspended and caused to rotate so that the magnetic core is evenly sintered. However, since the heating tubes of some sintering devices are installed on the upper side or the lower side of the sintering furnace, it is not convenient to change the heating surface of the magnetic core simply by rotating it. If the heating tubes are installed on the upper side of the sintering furnace, it is not convenient to sinter the bottom of the magnetic core by rotating the magnetic core, which makes the uniform sintering efficiency of the magnetic core low. At the same time, the magnetic core needs to be cooled after sintering. The existing cooling method is to cool it in the original sintering furnace, which will reduce the temperature in the sintering furnace. When the next batch of magnetic cores are sintered, the sintering furnace needs to be preheated again, which prolongs the sintering time. Therefore, after research, a manganese-zinc ferrite core sintering device is provided. When in use, the magnetic cores are arranged in sequence in the first discharge frame and the second discharge frame, the cover plate fixes the magnetic cores, and the transmission member rotates the rotating rod to make the first discharge frame and the second discharge frame rotate the bottom of the magnetic core or even any side that is not heated to the upper side, thereby ensuring that the magnetic core is fully heated. The sintered magnetic core is moved to the cooling box for cooling by the sliding of the moving plate in the slide groove. The magnetic core is separated from the sintering box and the cooling box, which can not only improve the cooling effect, but also will not reduce the temperature in the sintering box, thereby solving the above-mentioned defects.

[0031] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Please refer to Figure 1-Figure 7 The embodiment of the utility model provides a manganese-zinc ferrite core sintering device, including a base 1, a sintering box 2 is arranged at one end of the upper side of the base 1, the sintering box 2 is sintered by a heating tube 24 installed on the upper side, and a controller 4 is installed on one side of the base 1, and the controller 4 can control the motor of the entire device.

[0033] A slide groove 11 is provided on the upper surface of the base 1, and a uniform sintering mechanism 5 is slidably connected in the slide groove 11;

[0034] The uniform sintering mechanism 5 includes a movable plate 51 whose bottom is slidably connected to the slide groove 11. A screw rod 12 is rotatably arranged in the slide groove 11. The screw rod 12 is threadedly connected to the lower side of the movable plate 51. The screw rod 12 is driven by a motor. When the screw rod 12 rotates, the movable plate 51 slides automatically.

[0035] Since a hollow column 52 is arranged on the movable plate 51, a first material discharging frame 53 and a second material discharging frame 54 arranged vertically are rotatably arranged on one side of the hollow column 52. The first material discharging frame 53 and the second material discharging frame 54 are used to place the magnetic core. Through the rotation of the first material discharging frame 53 and the second material discharging frame 54, all positions of the magnetic core can be sintered upward.

[0036] Specifically, the first discharging frame 53 and the second discharging frame 54 are rotatably connected to the hollow column 52 through two rotating rods 56, and the two rotating rods 56 pass through the hollow column 52 and are connected to the transmission member 57. The transmission member 57 is two pulleys respectively connected to one end of the two rotating rods 56, a belt is mounted on the pulley, and one pulley is driven by a motor.

[0037] In addition, a cover plate 55 is provided on the upper side of the first material discharging frame 53 and the second material discharging frame 54. The cover plate 55 is fixed by a clamping block 58. The cover plate 55 prevents the magnetic core from falling during rotation. The cover plate 55, the first material discharging frame 53 and the second material discharging frame 54 all adopt a mesh design to facilitate heating of the magnetic core.

[0038] After the magnetic core is sintered, it is moved to one side of the sintering box 2 and placed in a cooling box 3. A cooling fan 31 is installed on the upper side of the cooling box 3 for cooling. The slide groove 11 and the screw rod 12 extend into the interior of the cooling box 3.

[0039] In order not to affect the sintering and cooling of the magnetic core, a sliding hole 37 is provided on the upper side of the feed port of the cooling box 3 , and a second sealing door 32 is slidably arranged in the sliding hole 37 , and the second sealing door 32 seals the cooling box 3 .

[0040] Secondly, tracks 33 are set on both sides of the feed port of the cooling box 3, and the two sides of the second sealing door 32 slide in the two tracks 33 respectively. The second sealing door 32 is limited by the tracks 33 to ensure the stable movement of the second sealing door 32. At the same time, a screw rod 36 is rotatably set in one of the tracks 33. The screw rod 36 is threadedly connected to the second sealing door 32. The screw rod 36 is driven by a motor to improve the degree of automation of the magnetic core sintering.

[0041] Furthermore, a moving groove 23 is provided on the upper side of the feed port of the sintering box 2, and a first sealing door 21 is slidably arranged in the moving groove 23. The first sealing door 21 seals the sintering box 2 to improve the efficiency of the magnetic core sintering.

The first connecting rod 22 and the second connecting rod 35 are connected by a connecting tube 34. The first sealing door 21 and the second sealing door 32 are connected together by the connecting tube 34, the first connecting rod 22 and the second connecting rod 35. When the second sealing door 32 moves upward, it can move with the first sealing door 21, so that the operator can clearly see the magnetic core entering the cooling box 3. Since the connecting tube 34 has a certain length, when the second connecting rod 35 is slid into the connecting tube 34, the second connecting rod 35 is separated from the second sealing door 32. At this time, the first sealing door 21 and the second sealing door 32 can be separated.

[0043] In summary, a manganese-zinc ferrite core sintering device according to an embodiment of the utility model has the following working principle: the core is placed in a first discharge frame 53 and a second discharge frame 54, fixed by a cover plate 55 and a clamping block 58, and the movable plate 51 moves the core to the sintering box 2 for sintering. During sintering, the transmission member 57 causes the two rotating rods 56 to rotate with the first discharge frame 53 and the second discharge frame 54, so that all positions of the core can be heated upward. After sintering, the second sealing door 32 is moved upward, and the movable plate 51 is moved to the cooling box 3 for cooling.
