Description

Demoulding device for winding magnetic core

Technical Field

The utility model relates to a system magnetic core preparation field, concretely relates to shedder of convoluteing magnetic core.

Background

A wound core of soft magnetic material such as oriented silicon steel is widely used in a magnetic collection circuit of a current (voltage) sensor. A generally wound magnetic core is wound with a mold having an outer dimension equal to an inner dimension of the magnetic core as a core mold. As shown in fig. 1, after the magnetic core 101 is wound, the magnetic core 101 must be separated from the core mold 100, that is, a mold release treatment is performed. As shown in fig. 2, conventionally, a stopper 102 having holes with the same matching size is manufactured according to the internal size of a magnetic core 101 (i.e., the size of the core 100), the bottom end of the core 100 is engaged with the holes of the stopper 102, the magnetic core 101 is hung on the surface of the stopper 102, and the core 100 is removed from the magnetic core 101 in the longitudinal direction by tapping with a hammer or pressing the top end of the core 100 with a cylinder.

However, in the actual production, due to the fact that the specifications of the magnetic cores are various, the magnetic cores of each specification need to be manufactured with stop irons with different hole sizes, and the manufacturing of a large number of stop irons is time-consuming and labor-consuming and is inconvenient to manage.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects in the prior art, the demolding device capable of meeting the demolding requirements of the wound magnetic core of any specification is provided.

The technical scheme is as follows: in order to achieve the above object, the utility model provides a shedder of coiling magnetic core, including drawing of patterns dish and four gibs, be provided with square drawing of patterns hole on the drawing of patterns dish, the symmetry is provided with four sliding trays on four inner walls in square drawing of patterns hole respectively, and four gibs cooperate respectively at four sliding trays, the gib can remove along the sliding tray, the top department that lies in four sliding trays is provided with the screw of setting up that is used for fixing the gib.

The design principle of the utility model is that: the four clamping irons can move to the four sides of the magnetic core mold close to the square demolding hole through the movement of the four clamping irons in the sliding groove, and then the four clamping irons are fixed after being tightened by the fastening screw, so that the four clamping irons can limit and guide the magnetic core mold, the effect of the hole of the original blocking iron is equal, the four clamping irons can support and block the magnetic core, the effect of the original blocking iron is equal, and the relative positions of the four clamping irons can be adjusted, so that the magnetic core mold can be matched with the magnetic core molds of various specifications.

Furthermore, the demoulding disc is a circular demoulding disc, the square demoulding holes are formed in the circle center of the demoulding disc, and the four sliding grooves are symmetrically arranged in the radial direction of the demoulding disc.

Furthermore, the fastening screw is positioned in the middle of the sliding groove, so that the fixing effect is improved.

Furthermore, the end parts of the clamping iron extend towards the two ends respectively, so that the contact area between the clamping iron and the magnetic core mold can be increased, a limiting effect can be achieved, and the clamping iron is prevented from being integrally retracted into the sliding groove.

Further, the end part of the clamping iron extends upwards to form an extension part, and the top surface of the extension part is kept horizontal with the top surface of the demoulding disc.

Has the advantages that: compared with the prior art, the utility model, because the relative position of four blocks is adjustable, can adapt to the drawing of patterns requirement of any specification coiling magnetic core, not only need not to make a large amount of butts, the time of having practiced thrift, the cost is saved has improved the convenience of device management moreover.

Detailed Description

The present invention will be further clarified by the following description with reference to the attached drawings and specific examples, which should be understood as being merely illustrative of the present invention and not limiting the scope of the present invention, and modifications of various equivalent forms of the present invention by those skilled in the art after reading the present invention, all fall within the scope defined by the appended claims of the present application.

As shown in fig. 3 and 4, the utility model provides a coiling magnetic core's shedder, including drawing of patterns dish 1 and four gibs 2, drawing of patterns dish 1 is circular drawing of patterns dish, its centre of a circle position is provided with square drawing of patterns hole 4, be provided with sliding tray 3 on four inner walls of square drawing of patterns hole 4 respectively, and four sliding tray 3 set up according to the radial symmetry of drawing of patterns dish 1, four sliding tray 3 all are located the bottom of square drawing of patterns groove 4, four gibs 2 cooperate respectively in four sliding tray 3, gib 2 can remove along sliding tray 3, the top department that lies in four sliding tray 3 intermediate positions on drawing of patterns dish 1 is provided with the screw 5 of setting up that is used for fixing gib 2, the tip of gib 2 extends to both ends respectively, and the tip of gib 2 upwards extends and forms extension 21, the top surface of extension 21 keeps the level with the top surface of drawing of patterns dish 1, the top surface of extension 21 keeps the

In the present embodiment, the demolding device with the above structure is used to demold the wound core 101 with a square internal dimension structure, and the specific process is as follows: firstly, a wound core 101 to be demolded is placed on the four extension portions 21, the bottom end of the core mold 100 is positioned between the four clamping bars 2, then the four fastening screws 5 are respectively loosened, the four clamping bars 2 are respectively moved to be close to the four sides of the core mold 100 along the respective sliding grooves 3, then the four fastening screws 5 are respectively tightened, the bottoms of the fastening screws 5 are tightly pressed on the clamping bars 2, the fixing of the clamping bars 2 is realized, finally, the top end of the core mold 100 is pressed by using a hammer strike or an air cylinder, and the core mold 100 falls under the action of pressure until the wound core 101 is completely separated from the wound core 101, so that the demolding is completed.
