Abstract
The utility model discloses an improved magnetic strip structure of an electromagnetic oven. The improved magnetic strip structure comprises a horizontal magnetic strip; and a plurality of stiffening ribs are arranged at the bottom of the horizontal magnetic strip, the cross section of the horizontal magnetic strip is semicircular, and a transition circular arc is arranged at the junction of the stiffening ribs and the bottom plane of the horizontal magnetic strip. As the stiffening ribs are arranged at the bottom of the horizontal magnetic strip, the improved magnetic strip structure of the electromagnetic oven can reduce the deformation of the magnetic strip during the sintering process with the simple structural improvement, thereby improving the quality of a finished product of the magnetic strip of the electromagnetic oven.
Description
Technical field
The utility model relates to a kind of electronic devices and components, particularly relates to a kind of structure of magnetic core, and this magnetic core is mainly used in the disk coil of electromagnetic oven.
Background technology
Along with people's quality of life improves constantly, household electrical appliance are also more and more.The appearance of electromagnetic oven provides more facility for people's life.Magnetic strip of electromagnetic oven is an important devices of electromagnetic oven the inside, and its processing is mainly adopted forcing press compression moulding and formed by high temperature sintering.In the magnetic stripe sintering process,, can produce the magnetic stripe problem on deformation because its density, thickness etc. is inhomogeneous.In order to solve the magnetic stripe problem on deformation, the technical staff generally adopts and optimizes the magnetic stripe product structure, and solves by the modification of compacting tool set.As publication number is that the Chinese patent of CN1426075A discloses a kind of Soft Magnetic Ferrite Magnetic Core Forming Method And Die Structure, it is in order to reduce the dimensional tolerance of the newel FERRITE CORE thinner than limit pin, use two-way mechanical press to suppress blank up and down, keep flat shape with three legs of blank and come moulding, blank is pressed into the font of saying of the outside protrusion of newel.After saying font blank sintering,, grind off redundance at twice, obtain required finished product with mill processing by required magnetic core finished form and dimensional requirement.Mould uses single counterdie, convex shape in the middle of counterdie is made, invaginated type in the middle of patrix is made.Adopt this method can effectively solve the yielding and big problem of dimensional tolerance of FERRITE CORE sintering, but its complex process, mould structure is also complicated, and its manufacturing cost is higher relatively.
The utility model content
The purpose of this utility model is to provide a kind of improved magnetic strip of electromagnetic oven structure, reduces the distortion that magnetic stripe produces with simple architecture advances in sintering process, improves the finished product quality of magnetic stripe.
Technical solutions of the utility model are: a kind of improved magnetic strip of electromagnetic oven structure, comprise horizontal magnetic strip, and be provided with plurality of strengthening ribs in the bottom of described horizontal magnetic strip.
As preferably, described reinforcement is at least three, lays respectively at the centre of horizontal magnetic strip bottom and near end positions.
As preferably, its cross section of described reinforcement is semicircle.
As preferably, described reinforcement and described horizontal magnetic strip base plane junction also are provided with transition arc.
By the technical solution of the utility model, its reinforcement is used for preventing that horizontal magnetic strip from deforming at high-temperature sintering process, and the employing circular cross-section then helps the processing of mould, and prevents that by transition arc junction stress is concentrated, prevents cracking.By the utility model, reduced the distortion of magnetic strip of electromagnetic oven finished product, improved the quality of finished product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Referring to Fig. 1, a kind of improved magnetic strip of electromagnetic oven structure comprises horizontal magnetic strip 1 and vertical magnetic stripe 5.Described vertical magnetic stripe 5 is separately positioned on the two ends near described horizontal magnetic strip 1, forms the U font.There is a step 5a junction in the described horizontal magnetic strip of lateral surface of described vertical magnetic stripe 5.Be provided with three reinforcements 3 in the bottom 2 of described horizontal magnetic strip 1, be arranged in the middle of the described horizontal magnetic strip 1 respectively and the two ends of close horizontal magnetic strip 1, be transversely arranged, its length is corresponding to the width of described horizontal magnetic strip 1 bottom surface; Described at the reinforcement near horizontal magnetic strip 1 two ends, its center is corresponding to described vertical magnetic stripe 5.Described reinforcement 3 is evenly distributed at the bottom of horizontal magnetic strip.The cross section of described reinforcement 3 is semicircle, but as another kind of scheme, rectangle, triangle or arc-shaped curved surface can be made in the cross section of described reinforcement 3.Also be provided with transition arc 4 at described reinforcement 3 with junction, described horizontal magnetic strip 1 bottom surface.
As an embodiment of the present utility model, mainly be in order to further specify the technical solution of the utility model, to make invention thought of the present utility model know more and be convenient to and understand.To the utility model multiple shifting gears can be arranged as those skilled in the art, such change does not think and breaks away from scope of the present utility model that what all were such will be included within the scope of this claim the conspicuous modification of described those skilled in the art.
