Detailed Description
In order to make the technical solution, the purpose and the advantages of the present invention more apparent, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 4, the method for preparing a magnetic core of an open-type transformer of the present invention includes the following steps:
s1, selecting a proper magnetic core material, and winding to obtain a circular magnetic core base block;
s2, carrying out heat treatment on the prepared magnetic core base block;
s3, performing paint dipping treatment on the magnetic core base block obtained by the heat treatment;
s4, baking and curing the magnetic core base block obtained by the dip coating treatment, and performing molding treatment on the magnetic core base block in the baking treatment process;
and S5, cutting the magnetic core base block obtained by the molding and baking curing treatment to obtain two semi-annular mutual inductor magnetic core blocks.
The molding treatment process comprises the following steps:
(1) an inner die matched with the inner ring side of the magnetic core base block in shape is arranged at the position of the inner ring side of the magnetic core base block, and the inner die can be selected to be applied to a cylindrical module; so that the inner ring side of the magnetic core base block and the cylindrical module form a close contact fit.
(2) And uniformly and continuously applying radially inward molding pressure to the outer periphery of the magnetic core base block by using a certain molding outer die, wherein the pressure range of the molding pressure is 5-10N.
The setting application of the shaping external mold is as follows: the magnetic core clamping device comprises at least two clamping pieces, wherein each clamping piece is encircled to form a ring shape, and a clamping side 61 of each clamping piece is combined to encircle a circular clamping space 7 for placing the magnetic core base block; each clamping piece block is connected with an elastic piece, and under the action of the elastic force of the elastic piece, the clamping piece blocks have mutually close clamping matching actions to form a tendency of narrowing the clamping space 7; when the shaping outer die stably clamps the magnetic core base block, the inner ring side surface of each clamping piece is tightly attached and contacted with the outer peripheral side surface of the magnetic core base block.
The outer periphery of each clamping piece block can be connected and extended with a connecting piece, the elastic piece can be applied to a spring 3, so that the spring 3 is provided with a plurality of sections, the tail ends of the plurality of sections of springs 3 are connected to the connecting pieces to form a ring shape, and under the action of the reset elastic force of each spring 3, the clamping pieces have corresponding tendency of approaching each other.
In the actual production process, or due to the problems of cost control and processing precision, transition or not enough flatness exists between the clamping sides 61 of the clamping blocks, the enclosing combination is difficult to arrange in a perfect circle shape, so the combination of the clamping blocks and the spring 3 with more quantity or the shape deformation of the clamping space 7 in the clamping blocks is easily caused; as a preferred embodiment, in the sizing external mold, the clamping piece block is applied as two pieces, namely a first clamping piece 1 and a second clamping piece 2 which are symmetrically arranged at two opposite sides; the first clamping piece 1 and the second clamping piece 2 are arranged in a semi-annular shape, and the clamping space 7 is formed between the opposite sides of the first clamping piece 1 and the second clamping piece 2.
The outer periphery of the first clamping piece 1 is provided with a first positioning groove 11, the outer periphery of the second clamping piece 2 is provided with a second positioning groove 21, and the first positioning groove 11 and the second positioning groove 21 are in abutting fit to form an attaching groove for positioning and attaching the spring 3.
The connecting member can be selectively applied as a bolt 5, such that a screw hole 4 is formed in the outer peripheral side of the first clamping member 1 at the central position thereof and extends in the radial direction thereof, and the bolt 5 is screwed into the screw hole 4 to form a fixing.
The spring 3 is applied as a strip, the head end of the spring 3 is positioned and connected to one side of the bolt 5 away from the position of the screw hole 4, the spring 3 is arranged around the outer peripheral sides of the first and second clip members 1 and 2 under the limitation of the attaching groove, and the tail end of the spring 3 is positioned and connected to the other side of the bolt 5 away from the position of the screw hole 4.
The molding outer die on the outer peripheral side is matched with the inner die on the inner ring side, so that the magnetic core base block in the baking and curing process can be continuously stressed, and the molding requirement of the magnetic core base block can be met. After the molding treatment, as shown in fig. 6, the end surface cracks of the magnetic core can be effectively subjected to the matching treatment, and the production application requirements of the high-quality magnetic core can be met.
When the shaping external mold is used for clamping, a release agent can be coated between the clamping side 61 of the shaping external mold and the magnetic core base block so as to facilitate the subsequent demolding treatment of the magnetic core base block.
Due to the structural form of the shaping outer die or the process problems, the connection transition positions of the first clamping piece 1 and the second clamping piece 2 are not smooth, and the clamping joint ends 62 of the magnetic core base block with the shaped magnetic core at the connection transition positions on the two sides are deformed to a certain degree.
Cutting marks corresponding to the clamping joint ends 62 at the two ends can be made in the cutting treatment process of the molded magnetic core base block; and the cutting mark is used for half-open cutting treatment, so that the deformed parts of the clamping joint ends 62 at two sides are treated along with the cutting loss, thereby obtaining two standard half-ring-shaped transformer magnetic core blocks, and meeting the subsequent assembly application requirements of the open-type transformer.
The above description is only a preferred embodiment of the present invention, and those skilled in the art may still modify the described embodiment without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as the protection scope of the present invention.
