Abstract
The utility model discloses a Neodymium iron boron magnet firing device which comprises a box body with an opening of an upper portion and a cover body. The cover body is arranged on an opening place of the upper portion of the box body. A bulging portion fit with the opening of the upper portion of the box body is arranged on the bottom of the box body. The lower bottom surface of the bulging portion is parallel with a horizontal plane. The box body can be used for replacing the cover body and costs of producing a lot of cover bodies are saved. Due to the fact that the bulging portion is arranged in the box body, placing in fold can be arranged among the box bodies. Occurrence of a phenomenon that slipping when the firing device is used in fold is avoided and code putting efficiency of the box body is increased. A plurality of products are fired once and production efficiency of the products is effectively improved.
Description
Technical field
The utility model relates to the manufacture field of ferrimagnet, is specifically related to the neodymium iron boron magnetic body sintering equipment.
Background technology
Neodymium iron boron magnetic body is in process, the neodymium iron boron powder will be by vacuum-sintering by the neodymium iron boron blank of compacting aftershaping, the sintering equipment that holds the neodymium iron boron blank comprises box body, each box body is provided with supporting lid, easily skid each other when existing sintering equipment is put at the base, and can topple in entering the stove moving process, the problem such as landing.
Summary of the invention
The purpose of this utility model provides a kind of box body to be possessed the lid function and is convenient to stablize each other the neodymium iron boron magnetic body sintering equipment that stacks layout.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of neodymium iron boron magnetic body sintering equipment comprises the box body of open topped, and the lid that is located at box body open topped place, it is characterized in that: the bottom of box body is provided with the uncovered protuberance that matches with box body top, and the bottom surface of protuberance is parallel with horizontal plane.
Owing to adopt above technical scheme, box body of the present utility model bottom is provided with the uncovered protuberance that matches with box body top, the bottom surface of protuberance is parallel with horizontal plane, box body can be stablized placement like this, and box body can replace lid to use, saved the cost of producing a large amount of lids, box body arrange protuberance structure so that can be stable between box body and the box body stack placement, avoided sintering equipment to stack the generation of skidding when using, increase the efficient of piling up of box body, once sintered a plurality of product improves the production efficiency of product effectively.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that a lid and two box bodys stack placement.
The specific embodiment
A kind of neodymium iron boron magnetic body sintering equipment, comprise the box body 20 of open topped, and the lid 10 that is located at box body 20 tops, the bottom of box body 20 is provided with the uncovered protuberance that matches 21 with box body 20 tops, the bottom surface of protuberance 21 is parallel with horizontal plane, and box body 20 can be stablized placement like this.Box body of the present utility model 20 bottoms are provided with the uncovered protuberance that matches 21 with box body 20 tops, stack when placing box body 20, the box body 20 that is positioned at the top naturally consist of its time square box 20 ' lid, the box body 20 that just is positioned at the top add one independently lid 10 get final product, saved the cost of producing a large amount of lids 10, and box body 20 stacks the lid of naturally having finished lid 10 when placing and puts process, has saved the operating time.Simultaneously, box body 20 arrange protuberance 21 structure so that box body 20 can be stable stack placement, avoided the generation of skidding when sintering equipment uses in the prior art, the sintering equipment that stacks layout is entering the movement that the stove process also can be stable, increased the efficient of piling up of box body 20, once sintered a plurality of product, the production efficiency of Effective Raise product.
Further, the capping middle position that described lid 10 is positioned at box body 20 open-position-sides is provided with the protuberance 11 that extends to the box chamber, the periphery of protuberance 11 and uncovered inside edge coincide, and the capping of the protuberance 11 place sides on the described lid 10 and box body 20 open-mouth end faces fit.Like this, lid 10 covers when the open-mouth of the box body 20 that is positioned at the top, the utlity model has good sealing effectiveness, can avoid the neodymium iron boron blank in sintering process with contact with air generation oxidation.
The utility model goes for the sintering of the neodymium iron boron magnetic body of various shape, all can such as the neodymium iron boron magnetic body of cuboid or cylindrical shape.
