Abstract
The utility model discloses a soft magnetic ferrite magnetic core sintering bearing structure, including underframe and upper ledge, be equipped with a plurality of support columns between underframe and the lower frame, the center of underframe is equipped with ventilative net. Compared with the prior art, the utility model has the advantages that: : the utility model discloses a ventilative net of underframe combines with the soft magnetic ferrite magnetic core, easily gaseous abundant flow the in the fritting furnace for the bottom of soft magnetic ferrite magnetic core and backing plate contact is at the smooth binder removal of the in -process of sintering, thereby has reduced the fracture of product, improves soft magnetic ferrite magnetic core product row yielding, support column between underframe and the lower frame makes also binder removal smoothly of side.
Description
Technical field
The utility model relates to a kind of soft magnetic ferrite production technique instrument, is specially a kind of magnetic ferrite magnetic core sintering supporting structure.
Background technology
Magneticsubstance is as the functional materials indispensable in national economy every field, its output and usage quantity become one of mark of a measurement national economy and Information Technology Development degree, particularly soft magnetic materials, along with electronics develops to compact, integrated, intelligent and multifunction direction, the development of various magnetic ferrite magnetic core is swift and violent. Magnetic ferrite magnetic core is member important in magneticsubstance, is widely used in the electronic devices and components such as various transformer, inductance, wave filter.
Existing magnetic ferrite magnetic core needs due to moulding process, and the magnetic ferrite magnetic core before sintering, often containing a certain amount of PVA sizing agent, therefore can be vented with sizing agent high-temp combustion in sintering process, and the row of being commonly called as moulds. In prior art, magnetic ferrite magnetic core is sinter on smooth support platform and become mostly, with support platform contact magnetic core bottom compare to close and be not easy to row and mould, make PVA sizing agent can not volatilize in the product, owing to row moulds the product freely not making to have sintered, cracking phenomena easily occurs, affect product quality. Disclosing a kind of magnetic ferrite magnetic core sintering on State Intellectual Property Office website and support backing plate, this back up pad comprises the fire-resistant porous layer of surface layer and base layer support layer, and supporting layer is provided with ventilative mechanism so that magnetic ferrite magnetic core is easy to row in sintering process and moulds. But the permeability of the back up pad of this structure also receives the restriction of Zheng Chengcheng and surface layer, ventilation property does not reach maximum.
Practical novel content
The purpose of this utility model overcomes a kind of magnetic ferrite magnetic core sintering supporting structure of the prior art, the position that this supporting structure contacts with magnetic ferrite magnetic core is only provided with gas-permeable nets, therefore its ventilation property reaches maximum so that magnetic ferrite magnetic core farthest obtains row in sintering process and moulds.
The technical solution of the utility model is achieved in that a kind of magnetic ferrite magnetic core sintering supporting structure, comprises end frame and upper frame, is provided with some pillar stiffeners between frame of the described end and lower frame, and the center of frame, the described end is provided with gas-permeable nets.
As preferably, frame of the described end and lower frame are the square or rectangular structures being made up of refractory materials.
Compared with prior art, advantage of the present utility model is as follows: the utility model is combined with magnetic ferrite magnetic core by end frame gas-permeable nets, it is easy to sintering furnace gas fully flow, the bottom that magnetic ferrite magnetic core is contacted with backing plate arranges glue smoothly in the process of sintering, thus decreasing the cracking of product, it is to increase soft ferrite magnetic core products makes rate; Pillar stiffener between end frame and lower frame makes side also can arrange glue smoothly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is as follows:
Embodiment: as shown in Figure 1: a kind of magnetic ferrite magnetic core sintering supporting structure, comprises end frame 1 and upper frame 2, be provided with some pillar stiffeners 3 between frame of the described end and lower frame, and the center of frame, the described end is provided with gas-permeable nets. End frame described in 4 and lower frame are the square or rectangular structures being made up of refractory materials.
Above-mentioned supporting structure is combined with magnetic ferrite magnetic core by end frame gas-permeable nets, it is easy to sintering furnace gas fully flow, the bottom that magnetic ferrite magnetic core is contacted with backing plate arranges glue smoothly in the process of sintering, thus decreasing the cracking of product, it is to increase soft ferrite magnetic core products makes rate; Pillar stiffener between end frame and lower frame makes side also can arrange glue smoothly.
Finally, it should be noted that above embodiment is only the more representational example of the utility model. Obviously, the technical solution of the utility model is not limited to above-described embodiment, it is also possible to have many distortion. All distortion that the those of ordinary skill of this area can directly derive from content disclosed in the utility model or associate, all should think protection domain of the present utility model.
Claims (2)
