Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic core production, and particularly relates to a magnetic core sintering device. Background Art

[0002] A magnetic core is made of magnetic materials and can be used to store and amplify electromagnetic signals. It is an indispensable part of electronic components. When producing magnetic cores by the pressing forming process, magnetic powders are mixed in proportion and then put into a forming mold, and the powders are formed by pressing. The pressed magnetic cores need to be sintered and sprayed, and finally magnetic cores with magnetism are formed. Among them, sintering is the last step in manufacturing magnetic cores. The purpose of sintering is to solidify the particles inside the magnetic core into one body to improve the magnetic properties and thermal stability of the magnetic core.

[0003] When the magnetic core is sintered, the sintered magnetic core needs to be cooled. In the existing magnetic core cooling methods, the natural cooling speed is too slow. For liquid cooling, the magnetic core needs to be taken out of the sintering chamber for liquid cooling. During the taking-out process, the temperature of the magnetic core is high, and the operation is inconvenient. Moreover, the device for automatically sintering and cooling cannot ensure the airtightness of the sintering chamber. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a magnetic core sintering device, which has a simple structure. After sintering the magnetic core, the magnetic core can be cooled without taking it out, which can improve the working efficiency. Moreover, when sintering in the sintering chamber, the sealing property is good, the heat dissipation is low, and the practicability is strong, which is suitable for popularization.

[0005] The utility model provides the following technical solution: a magnetic core sintering device, including a main box body. A sintering chamber is arranged above the main box body, and a cooling chamber is arranged below the main box body. An opening and closing door is arranged at the opening of the cooling chamber through a rotating shaft. Symmetric through tracks are arranged near both sides of the opening and closing door. An outer support frame penetrates through the through tracks. A handle is fixedly arranged on the outer side of the opening and closing door of the outer support frame. The outer support frame penetrates into the opening and closing door and is fixedly provided with an inner support frame on the side facing the sintering chamber. Heat insulation walls are arranged on the inner wall of the sintering chamber and at the corresponding opening of the sintering chamber of the opening and closing door. The inner support frame bends to the front of the heat insulation wall of the opening and closing door and is fixedly provided with an array of trusses. An array of a plurality of placing grooves is arranged on the trusses.

[0006] The bent part of the inner support frame is an arc-shaped frame. A clamping groove matching with the arc-shaped frame is arranged on the heat insulation wall on the inner wall of the sintering chamber corresponding to the arc-shaped frame. The position of the through track satisfies that when the opening and closing door is closed, it fits on the heat insulation wall of the sintering chamber.

[0007] Preferably, an array of water pipes is arranged on both sides in the cooling chamber. An array of atomizing nozzles is arranged on the side of the water pipes facing the placing grooves. A water receiving tank is arranged at the bottom of the cooling chamber, and a water discharge port is arranged at the bottom of the water receiving tank.

[0008] Preferably, the vertical height of the through-rail satisfies that when the outer support frame is at its uppermost end, the position of the arc-shaped frame is opposite to that of the card slot, and when the outer support frame is at its lowermost end, the placement slots of the array are opposite to the cooling chamber.

[0009] Preferably, the two sides of the outer support frame located inside the through-rail are in close contact with and slidably connected to the through-rail.

[0010] The beneficial effects of the present utility model are as follows: The structure is simple. After sintering the magnetic core, the magnetic core can be cooled without taking it out, which improves work efficiency. Moreover, when sintering in the sintering chamber, the sealing performance is good, the heat dissipation is low, and the practicability is strong. Specifically as follows:

[0011] The present utility model is provided with a through-rail. After placing the magnetic core in the placement slot, the upper handle is used to move the outer support frame to the uppermost end of the through-rail. At this time, the position of the arc-shaped frame is opposite to that of the card slot. The opening and closing door is closed, so that the arc-shaped frame is stuck on the card slot, and the through-rail is attached to the heat-insulating wall of the sintering chamber. At this time, the magnetic core is sintered. The closed sintering chamber has low heat dissipation. After the magnetic core is sintered, the opening and closing door is opened. At this time, under the action of gravity, the outer support frame slides down along the through-rail, driving the placement slot to descend. When the outer support frame slides to the lowermost part of the through-rail, the placement slot corresponds to the cooling chamber. After closing the opening and closing door, the placement slot extends into the cooling chamber, and the atomizing nozzle performs liquid cooling treatment on the magnetic core on the placement slot to complete rapid cooling. In this process, only by opening and closing the opening and closing door, it is possible to place the magnetic core in the cooling chamber without taking it out. BRIEF DESCRIPTION OF THE DRAWINGS

By manually lifting the outer support frame 6 with the handle 7, the two sides of the outer support frame 6 located inside the through tracks 5 are in contact with and slidably connected to the through tracks 5, so that the outer support frame 6 can slide smoothly downward on the through tracks 5. The outer support frame 6 penetrates into the inner side of the opening and closing door 2 facing the sintering chamber 3 and is fixedly provided with an inner support frame 9. Heat insulation walls 8 are provided on the inner wall of the sintering chamber 3 and at the corresponding opening of the opening and closing door 2 of the sintering chamber 3.

The vertical height of the through-rail 5 satisfies that when the outer support frame 6 is at its uppermost end, the positions of the arc-shaped frame 16 and the card slot 17 are opposite. When the opening and closing door 2 is closed, the arc-shaped frame 16 is inserted into the card slot 17, and the arc-shaped frame 16 blocks the card slot 17 and prevents the inner support frame 9 from descending. The position of the through-rail 5 satisfies that when the opening and closing door 2 is closed, it fits on the heat-resistant wall 8 of the sintering chamber 3.

After sintering the magnetic cores, the magnetic cores are cooled without taking out the magnetic cores, which improves the working efficiency. Moreover, the sintering chamber has good sealing during sintering, low heat dissipation, strong practicability, and is suitable for popularization.

[0024] Specifically, when in use, refer to Figure 1-3 , after placing the magnetic cores in the placement grooves 11, the upper handle 7 moves the outer support frame 6 to the uppermost end of the through-rail 5.

At this time, the magnetic cores are sintered. The closed sintering chamber 3 has low heat dissipation. After the magnetic cores are sintered, open the opening and closing door 2. At this time, under the action of gravity, the outer support frame 6 slides down along the through-rail 5, driving the placement grooves 11 to descend.
