Abstract
The invention discloses the technology for manufacturing a finished magnetic core. The technology for manufacturing the finished magnetic core comprises the following steps that pre-sintering, engraving and sintering are conducted on a formed magnetic core in sequence. According to the technology for manufacturing the finished magnetic core, due to the fact that the formed magnetic core is pre-sintered, engraving is convenient, the finished magnetic core is not prone to breakage, and the success rate is high; in addition, operation is easy, and the technology is easy to implement.
Description
Technical field
The present invention relates to manganese-zinc ferrite magnetic core manufacturing technology field, especially a kind of magnetic core finished product manufacture craft.
Background technology
Along with the development of magnetic material application, the competition in market is also more and more anxious strong, the pressure of enterprise in the face of how to deliver goods in the shortest time on the one hand, the problem that the competition Ye Shi enterprise of new product development aspect on the other hand has to face.The method of traditional fabrication magnetic core finished product, is to draw product drawing according to customer requirement, after client confirms, carries out die sinking, the series of process flow processs such as Mold Making completes and suppresses, sintering, and the final new product development cycle once at least must have more than two weeks.
In order to shorten this construction cycle, there is the engraving process of the magnetic patch of employing to prepare sample, its method is: the magnetic patch of the suitable size of different materials that is prepared in advance, by making finished product magnetic patch after normal sintering, when there being client to need product development, just use engraving machine to carve the magnetic core of required size with corresponding suitable magnetic patch; Construction cycle can foreshorten to 3～5 days greatly like this.But the finished product magnetic patch after sintering is as pottery, and hardness is very high, engraving very difficult, what this mode was brought is expensive and very low success rate.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of magnetic core finished product manufacture craft, easy and simple to handle, development-success ratio is high.
In order to realize foregoing invention object, the invention provides following technical scheme: a kind of magnetic core finished product manufacture craft, comprises following process: the magnetic core after moulding is carried out to presintering, engraving, sintering processes successively.
Further, the temperature of described presintering is 850～1200 DEG C, is incubated 30～90 minutes.
Further, the temperature of described presintering is 850～1000 DEG C.
Compared with prior art, the present invention has the following advantages: the magnetic core of moulding is carried out to presintering, and convenient engraving, and not fragile, success rate is high; Operation is simple.
Embodiment
Describe the present invention below in conjunction with embodiment, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of magnetic core finished product manufacture craft, comprises following process: the magnetic core after moulding is carried out to presintering successively, and pre-sintering temperature is 850～1200 DEG C, preferably 850～1000 DEG C, is incubated 30～90 minutes; And then through conventional engraving process and sintering process processing.
Therefore the blank of just moulding cannot be carved because intensity is very poor, and the magnetic patch that burns till finished product is due to hardness, as pottery, to carve difficulty very high, and the magnetic patch intensity and the hardness that obtain by the presintering of this technique are all applicable to carrying out Carving Machining.
What tradition was used while using the sample that burns till product engravings due to sintering is magnetic patch, and the product of producing with follow-up die sinking is compared very large uncertainty, can not represent follow-up volume production level; And after the present invention is engraved as required blank, then carry out sintering, therefore can represent follow-up volume production level; Problematic situation while there will not be the qualified and volume production of sample.
The present invention has adopted pre-sintering process, can supply cutting sample by Quick, has greatly reduced difficulty of processing, has improved the success rate of exploitation, improves the precision of product development simultaneously.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (3)
