Abstract
The invention discloses a kind of stereoscopic triangular coiled-core transformer iron core winding heart mould, this heart mould comprises main body, be provided with in the both sides of main body can with body portion from bar shaped iron block, be provided with one group of window being used for colligation iron core column in the inner side of bar shaped iron block and the junction of main body.The upper and lower end face of main body is band radian profile.Use between the lamination of this heart mould coiling compact, without wave, its knockdown structure be convenient to annealing after to iron core column colligation shaping, substantially increase iron core quality.
Description
Technical field
The present invention relates to a kind of transformer, specifically a kind of stereoscopic triangular coiled-core transformer iron core winding heart mould.
Background technology
As a kind of new distribution transformer, three-dimensional reel iron core transformer becomes a kind of trend of distribution transformer with the advantage of its dual-energy-saving.Manufacturing technology as the core iron core of three-dimensional reel iron core transformer is the most complicated.Particularly mould is immature especially diligently for iron core winding, and the iron core that coiling goes out cannot use greatly due to wave degree, causes doing over again or scrapping.
Summary of the invention
In order to overcome prior art Problems existing, the object of this invention is to provide a kind of stereoscopic triangular coiled-core transformer iron core winding heart mould, use between the lamination of this heart mould coiling compact, without wave, its knockdown structure be convenient to annealing after to iron core column colligation shaping, substantially increase iron core quality.
The object of the invention is to be achieved through the following technical solutions:
A kind of stereoscopic triangular coiled-core transformer iron core winding heart mould, it is characterized in that: this heart mould comprises main body, be provided with in the both sides of main body can with body portion from bar shaped iron block, be provided with one group of window being used for colligation iron core column in the inner side of bar shaped iron block and the junction of main body.
In the present invention, the upper and lower end face of main body is band radian profile.One group window is arranged on inside bar shaped iron block equably.
The present invention when coiling bar shaped iron block and heart mould main body as a whole.During coiling complete employing steel bandage colligation iron core column, bar shaped iron block is de-centrifugal mold main body under the drive of steel bandage, holds together, play a part auxiliary colligation with core limb.So just make between each of the iron core column of colligation more tight, disappear the wave of iron core column when reeling simultaneously, and iron core quality is improved greatly.
Heart mould main body upper and lower end face adopts slightly radian configuration design.In making iron core when reeling, silicon steel sheet is good in each the transition of heart mould, and coiling is tight.
Compared with prior art, advantage of the present invention is: when coiling bar shaped iron block and heart mould main body as a whole, heart mould main body upper and lower end face adopts slightly radian profile, make iron core silicon steel sheet when reeling good in each the junction transition of heart mould, coiling is tight, disappear the wave of iron core column when reeling, and iron core quality is improved greatly.
The most applicable three-dimensional reel iron core transformer iron core winding of the present invention is used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the schematic diagram of colligation iron core column of the present invention.
Embodiment
A kind of stereoscopic triangular coiled-core transformer iron core winding heart mould of the present invention, see Fig. 1, this heart mould comprises main body 1, is provided with the bar shaped iron block 2 that can be separated with main body 1 in the both sides of main body 1, and the thickness of bar shaped iron block can be 15mm.A group window 3 is provided with in the inner side of bar shaped iron block 2 and the junction of main body.One group window 3 is arranged on inside bar shaped iron block equably, is used for carrying out colligation iron core column 6 by steel bandage 5.Heart mould main body upper and lower end face adopts slightly radian profile 4, and make iron core silicon steel sheet when reeling good in each the junction transition of heart mould, coiling is tight, and disappear the wave of iron core column when reeling, and iron core quality is improved greatly.
When coiling bar shaped iron block and heart mould main body as a whole.During coiling complete employing steel bandage colligation iron core column, bar shaped iron block is de-centrifugal mold main body under the drive of steel bandage, holds together, play a part auxiliary colligation, as shown in Figure 2 with core limb.So just make between each of the iron core column of colligation more tight, disappear the wave of iron core column when reeling simultaneously, and iron core quality is improved greatly.
