Abstract
The utility model discloses a permanent magnet material sintering boat which comprises a carrying plate (1) and a plurality of vertically positioned support columns (3); wherein a plurality of uniformly distributed vent holes (4) are formed on the carrying plate (1), the support columns (3) are uniformly arranged along the periphery of the upper plane of the carrying plate (1), and are movably connected with the carrying plate (1). The permanent magnet material sintering boat has the advantages that the space in the sintering furnace can be effectively utilized, the utilization ratio of the sintering furnace can be increased, the energy consumption of the sintering furnace can be reduced, and the production cost can be reduced.
Description
Technical field
The utility model relates to a kind of ccontaining and support the device of sintered magnet when being used for the permanent-magnet material sintering, specifically is a kind of permanent-magnet material sintering boat.
Background technology
The permanent-magnet material sintering is that rare earth alloy ingot pulverize is formed alloy powder in magnetic field after the compression moulding, and sintering and tempering form in sintering furnace.Prior art ccontaining and the general structure of sintering boat that supports sintered magnet comprise circular material containing plate, retainer plate and are fixedly mounted on support column between material containing plate and the retainer plate that described material containing plate is provided with a plurality of equally distributed passages.In sintering, sintered body is placed on the material containing dish of sintering boat, then the sintering boat is placed on the heating pillar of sintering furnace and carry out sintering, in order to enhance productivity, general in sintering furnace the sintering boat of a plurality of carrying sintered magnets being stacked together carried out sintering.The permanent-magnet material sintering boat of this structure owing to fixedly connected with retainer plate with the material containing plate respectively in the two ends of support column, that is to say that the distance between material containing plate and the retainer plate is changeless.But aborning, burn the height difference of product, greater than the distance between material containing plate and the retainer plate, just need the sintering boat stack of multilayer highly to carry the product that is burnt as the height of fruit product to increase, perhaps change highly bigger sintering boat and carry product.There is following shortcoming in process of production in the sintering boat of this structure:
1, between the product height is greater than material containing plate and retainer plate apart from the time, adopt the sintering boat stack of multilayer highly to carry the product that is burnt to increase, so usually cause the useful space of multilayer stack sintering boat not make full use of, reduced the utilization rate of sintering furnace, increased the consumption of the energy.
2, adopt the highly bigger sintering boat of replacing to carry the product of institute's sintering,, when changing, need the three is changed simultaneously because material containing dish, retainer plate, the support bar three of sintering boat are fixed as one.If the height of the product of being fired is all different, this sintering boat that just requires to dispose a lot of differing heights carries product, has so just increased production cost.
The utility model content
The technical problems to be solved in the utility model is, overcomes above existing technological deficiency, provides a kind of and can effectively utilize the sintering furnace inner space, increases the utilization rate of sintering furnace, reduces the sintering furnace energy resource consumption, and the permanent-magnet material sintering boat that reduces production costs.
Technical solution of the present utility model is, a kind of permanent-magnet material sintering boat with following structure is provided: it comprises the material containing plate, the support column of a plurality of vertical placements, described material containing plate is provided with a plurality of equally distributed passages, described a plurality of support column evenly is provided with along the periphery on plane on the material containing plate, and described a plurality of support columns and material containing plate flexibly connect.
After adopting above structure, the utility model permanent-magnet material sintering boat compared with prior art has the following advantages: owing to omitted retainer plate, and support column and the flexible connection of material containing plate.When the product sintering, can select the support column of proper height according to the height of product, the support column of choosing is connected with the material containing plate gets final product, sintering boat with loading stocks stacks on the heated beam of sintering furnace then, height until stack reaches maximum effective depth in the sintering furnace, the sintering boat of this spline structure effectively utilizes the sintering furnace inner space, increase the utilization rate of sintering furnace, reduce the sintering furnace energy resource consumption, can select the support column of proper height to be connected according to the height of product in addition with the material containing plate, and whole sintering boat more need not be changed, can reduce production costs effectively like this.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Be illustrated in figure 1 as the permanent-magnet material sintering boat of prior art, it comprises material containing plate 1, retainer plate 2, support column 3, passage 4.
As Fig. 2, Fig. 3, shown in Figure 4;
The utility model permanent-magnet material sintering boat, it comprises material containing plate 1, the support column 3 of a plurality of vertical placements, and described material containing plate 1 is provided with a plurality of equally distributed passages 4, described a plurality of support column 3 evenly is provided with along the periphery on plane on the material containing plate 1, and described a plurality of support columns 3 flexibly connect with material containing plate 1.
Described flexible connection is meant to be had on the material containing plate 1 for the support column 3 movable blind holes of inserting.
The diameter of described support column 3 bottoms is equal to or slightly less than the internal diameter of blind hole.
Below only be described, but can not be interpreted as it is restriction claim with regard to the embodiment of the utility model permanent-magnet material sintering boat.The utility model is not limited to the structure of the foregoing description; material containing dish as the utility model permanent-magnet material sintering boat is circular; also can be square, polygon etc., all various variations of being done in the protection domain of the utility model claim are all in protection domain of the present utility model.
Claims (3)
1. permanent-magnet material sintering boat, it comprises material containing plate (1), the support column of a plurality of vertical placements (3), described material containing plate (1) is provided with a plurality of equally distributed passages (4), the periphery that described a plurality of support column (3) is gone up the plane along material containing plate (1) evenly is provided with, and it is characterized in that: described a plurality of support columns (3) flexibly connect with material containing plate (1).
