[0014] Compared with the prior art, this utility model provides a sintering sagger for the production of manganese-zinc magnetic rings, which has the following beneficial effects:
[0015] 1.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1
[0025] Please see Figures 1-5 This utility model discloses a sintering sagger for the production of manganese-zinc magnetic rings, including a sagger body 1 and a fixing member 3, wherein:
[0026] An air vent 12 is provided on the top of the box body 1, and a removable placement plate 2 is movably connected to the bottom of the box body 1. The surface of the placement plate 2 is provided with a plurality of evenly arranged ventilation holes 21.
[0027] The fixing component 3 includes multiple limiting discs 31 that can be detachably installed on the placement plate 2 for limiting and fixing the magnetic ring.
[0028] Please see Figure 3 The bottom of the placement plate 2 is symmetrically equipped with support legs 22, and a narrow cavity is formed between the bottom of the placement plate 2 and the bottom surface of the box body 1.
[0029] Specifically, the cavity at the bottom of the placement plate 2 can better increase airflow and reduce the occurrence of adhesion.
[0030] Please see the appendix Figure 5 The box body 1 has multiple air ports 13 symmetrically arranged on both sides, and the air ports 13 are connected to the cavity at the bottom of the placement plate 2.
[0031] Specifically, during sintering, protective gas can enter the bottom of the casing 1 from the atmosphere port 13 and then overflow from the vent hole 21 to protect the magnetic ring.
[0032] Furthermore, the ventilation holes 21 on the placement plate 2 are all rectangular holes, and the top positions of the four sides of the box body 1 are all provided with air grooves 12.
[0033] Please see Figures 1-2 The casing 1 is symmetrically equipped with connecting ear plates 11 on both sides. Two sets of connecting ear plates 11 are arranged in pairs on one side, and two sets of connecting ear plates 11 are arranged in single pairs on the other side.
[0034] In this embodiment, when different boxes 1 are placed and aligned, a single connecting lug 11 on one side of box 1 can be inserted between two sets of connecting lugs 11 on two boxes 1, so that the boxes 1 can be spliced together.
[0035] Example 2
[0036] Based on the above embodiment 1, please refer to the appendix. Figure 4 The bottom of the limiting plate 31 is equipped with a fixing pin 32, which is movably connected to and fits the vent hole 21. The bottom surface of the limiting plate 31 is in contact with the top surface of the placement plate 2.
[0037] Furthermore, a plurality of fixed contacts 33 are installed on the outer side of the limiting disk 31, which are equidistant from the center of the limiting disk 31, and all fixed contacts 33 are rounded.
[0038] In this embodiment, the magnetic ring is fitted onto the outer wall of the limiting disk 31. At this time, the position of the limiting disk 31 is fixed, and the fixing contact 33 on the outer side of the limiting disk 31 abuts against the inner wall of the inner ring of the magnetic ring, so that the position of the magnetic ring remains unchanged. Since the fixing contact 33 has rounded corners, it will not scratch the magnetic ring when fitting it.
[0039] Working principle and usage process of this utility model:
[0040] According to the size of the sintered manganese-zinc magnetic ring green (hereinafter referred to as the magnetic ring), a corresponding size limiting plate 31 is selected. After inserting the fixing pin 32 on the limiting plate 31 into the corresponding vent hole 21 on the placement plate 2, the magnetic ring can be fitted onto the outer wall of the limiting plate 31. At this time, the position of the limiting plate 31 is fixed, and the fixing contact 33 on the outer side of the limiting plate 31 abuts against the inner wall of the inner ring of the magnetic ring, so that the position of the magnetic ring remains unchanged. During sintering, the protective gas enters the box 1 through the atmosphere groove 12 and the atmosphere port 13 to protect the magnetic ring and form the magnetic ring in a high-temperature environment. After sintering is completed, the magnetic ring and the limiting plate 31 are removed, and the placement plate 2 can be taken out for cleaning to complete the sintering.
