Abstract
The utility model relates to a large-scale magnetic core, in particular to a novel magnetic core provided with the overflow grooves. A magnetic core provided with the overflow grooves comprises a base and a side plate, which is characterized in that: the base is opened with an overflow groove I at the back and the magnetic core is also opened with an overflow groove II in the middle of the facade. The utility model has the advantages of full gluewater volatilization, effectively avoiding the product breakage with high product quality, simple structure, reasonable design, etc.
Description
Technical field
The utility model relates to a kind of large-scale magnetic core, especially relates to a kind of novel magnetic core that is provided with the binder removal groove.
Background technology
As everyone knows, among the process of the medium-and-large-sized magnetic core of sintering manganese-zinc ferrite,, often in raw material, added PVA glue composition in the actual mechanical process for the ease of form forming magnetic core.Therefore, situations such as binder removal cracking just often appear in magnetic core easily in sintering process, and it has a strong impact on product quality, brings unnecessary economic loss to manufacturer.
The utility model is by being provided with the binder removal groove on magnetic core, thereby reaches the purpose of being convenient to gas communication and glue volatilization.
Summary of the invention
The utility model mainly is the technical problem that volatilization causes product cracking, poor product quality etc. inadequately fully, easily at existing in prior technology glue, provides a kind of glue to volatilize fully, can effectively avoid the magnetic core that is provided with the binder removal groove that product ftractures, product quality is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of magnetic core that is provided with the binder removal groove, constitute by base and side plate, and it is characterized in that described base back surface offers a binder removal groove I; Middle part, magnetic core front also offers a binder removal groove II.Among the process of the medium-and-large-sized magnetic core of sintering manganese-zinc ferrite, carry out gas communication by the binder removal groove, make the volatilization of PVA glue fully; Avoid and reduced the cracking phenomena of product effectively.
As preferably, described binder removal groove I is a trench structure, and its cross section is " recessed " font.It is rational in infrastructure, glue volatilization effect is obvious.
As preferably, described binder removal groove II is a groove shape structure, and its end is circular-arc.It is reasonable in design, and is simple in structure.
Therefore, the utlity model has glue volatilization fully, can effectively avoid product cracking, product quality height, characteristics such as simple in structure, reasonable in design.
Description of drawings
Accompanying drawing 1 is a kind of structural perspective of the present utility model.
Accompanying drawing 2 is another kind of structural perspective of the present utility model.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of magnetic core that is provided with the binder removal groove is made of base 1 and side plate 2, and base back surface offers a binder removal groove I3; Middle part, magnetic core front also offers a binder removal groove II4.Binder removal groove I is a trench structure, and its cross section is " recessed " font.Binder removal groove II is a groove shape structure, and its end is circular-arc.
Among the process of the medium-and-large-sized magnetic core of sintering manganese-zinc ferrite, carry out gas communication by the binder removal groove, make the volatilization of PVA glue fully; Avoid and reduced the cracking phenomena of product effectively.
Claims (3)
