Abstract
This utility model relates to an open step cutting iron core, which comprises a silicon steel belt and is characterized in that the silicon steel belt forms a group of multi-ring silicon steel iron core by coiling, and each ring of silicon steel comprises a cut achieved by a cutting. The iron core is achieved by coiling the silicon steel belt in the production process and is quite convenient. In the process of voltage transformer production, the loop is capable of convenient posting into the iron core through the cut due to the fact that each ring of silicon steel comprises a cut, and thereby being convenient. The magnetic resistance is relatively small, the flux consumption is low and the operation efficiency of the voltage transformer is relatively high due to the fact that each ring of silicon steel comprises only one section.
Description
Technical field
The utility model relates to a kind of transformer core, especially a kind of open-type stepping cutting iron core.
Background technology
Iron core is necessary parts of guaranteeing the transformer operate as normal, and different structures will inevitably influence the performance and the operating efficiency of transformer.With regard to the silicon steel structure that iron core relates to, " F " shape is generally arranged, " E " shape, " L " shape, " I " shape and " O " shape, wherein preceding four kinds by silicon steel thin slice punching moulding, repeatedly form iron core behind the dress according to certain rules again, and " O " shape directly forms iron core by the silicon strip coiling." F " shape, " E " shape and " L " shape generally are used to make miniature transformer; " I " shape (also be rectangle, comprise that corner is the inclined-plane) generally is used to make big-and-middle-sized transformer; " O " shape generally is used to make the transformer of special purpose.Adopt " F " shape, " E " shape, " L " shape, " I " is though the transformer of shape silicon sheet core is more convenient in the production of transformer is installed, and production cost is relatively low, because iron core needs assembling, magnetic resistance is bigger in the magnetic circuit that iron core forms, flux loss is big, and the operating efficiency of transformer is relatively low relatively, and operating frequency is generally lower; And adopt " O " though the transformer iron core of shape iron core is produced more convenient, magnetic resistance is less in the magnetic circuit that iron core forms, flux loss is little, the operating efficiency of transformer is higher relatively, can be in higher frequency operate as normal, but but relatively more difficult in the production of transformer is installed, production cost is higher relatively.
Summary of the invention
The purpose of this utility model is: the particular problem at the range transformer iron core of present employing exists separately provides a kind of new open-type stepping cutting iron core.
The purpose of this utility model is a kind of open-type stepping cutting iron core of realizing like this, comprises silicon strip, it is characterized in that: by the one group multi-turn silicon steel core of silicon strip by reeling and forming, every circle silicon steel contains one otch that cutting forms.
In the utility model: the thickness of described silicon strip is 0.18～0.35mm.
In the utility model: the incision site of every circle silicon steel stepping step on adjacent silicon steel moves back staggered successively.
Advantage of the present utility model is: because iron core is silicon strip to be reeled to form aborning, very convenient, because every circle silicon steel all contains otch one, in the transformer production process, coil can be inserted the iron core from otch easily, and is also more convenient; Because every circle silicon steel only contains one cross section (" L " shape, there are two cross sections at least in the every circle of " I " shape for " F " shape, " E " shape), magnetic resistance is less comparatively speaking, and flux loss is little, and the operating efficiency of transformer is higher relatively.
Description of drawings
Fig. 1 is the specific embodiment structural representation that the utility model relates to.
Among the figure, 1, the multi-turn silicon steel core, 2, otch.
Embodiment
Accompanying drawing discloses the structure of a specific embodiment of the present utility model without limitation, and the utility model will be further described below in conjunction with specific embodiment.
As seen from Figure 1, the utility model comprises by the one group multi-turn silicon steel core 1 of silicon strip by reeling and forming, and all contains one otch 2 that cutting forms on every circle silicon steel, and the position of this otch 2 is moved back staggered successively for the step of stepping on adjacent silicon steel.
During concrete enforcement, silicon strip can be wound into cylinder earlier according to designing requirement, again by the shape of product of hydraulic press along the cross-sectional direction compacting formation iron core of cylinder, annealing then, the stepping step moves back staggered successively cutting and forms otch on adjacent silicon steel at last, becomes the utility model related products.Can select the silicon strip of thickness range between 0.18～0.35mm in the production for use.
