Embodiment Construction

[0021] refer to figure 1 As shown, a flow chart of a method for manufacturing a ballast core according to a first embodiment of the present invention is disclosed. The method includes:

[0022] S101. Stamping production Type thin silicon steel sheet, the number of pieces Type thin silicon steel sheets are superimposed and bonded to form type silicon steel block. In one embodiment, this step is implemented as follows: first, silicon oxide is prepared, and the specification of the silicon oxide is 3000 mesh to 3500 mesh. Then mix silicon oxide and resin to form a mixture, heat the mixture of silicon oxide and resin, and use the heated mixture to bond several pieces Type thin silicon steel sheet. The thin silicon steel sheets to be bonded are formed after cooling type silicon steel block.

[0023] S102. Put two Type silicon steel blocks are spliced ​​in a relative manner to form a type complete core.

[0024] S103. Will The type magnetic core is heat treated i...

Abstract

The invention discloses a manufacturing method of a ballast iron core. The method comprises the following steps: fabricating profile thin silicon steel sheets through stamping, and superimposing and bonding a plurality of profile thin silicon steel sheets to form a profile silicon steel block; splicing two profile silicon steel blocks in an opposite mode, to form a profile magnetic core; and performing heat treatment on the profile magnetic core in inert gas environment, to eliminate the internal stress of the silicon steel sheets. The manufacturing method of the ballast iron core provided by the invention is simple in work and low in cost, is similar to the traditional profile iron core manufacturing process, but the formed profile iron core also has the performance advantages of an annular ballast and is low in iron loss.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a method for manufacturing an iron core of a ballast. Background technique [0002] Usually, the iron core of the ballast is made of thin silicon steel sheet of 0.3-0.5mm after processing and stamping type silicon steel sheets, and then stacked to form Silicon steel block, forming the iron core production. Although the iron core of this structure is simple in manufacturing process, with low cost. However, the iron core cannot wrap the coil wound on the magnetic core, so there are more free lines of magnetic force, low electromagnetic conversion efficiency, and high power consumption. [0003] The total loss of the ballast is related to many factors such as the shape and size of the cross-sectional area of ​​the iron core, the size of the window, the magnetic flux density, the thickness of the silicon steel sheet, and the frequency of the power supply. Therefore, in order t...
