Abstract
The method includes following steps: using die to pressing out I type thin silicon steel plates, and E type thin silicon steel plates; piling up thin silicon steel plates in same I shape and E shape to silicon steel block with certain thickness respectively; cutting I shaped and E shaped silicon steel block into two symmetrical 'a' blocks and two symmetrical 'b' blocks; putting 'a' block and 'b' block together to form magnetic yoke and core with shape of horizontal section being as cross type; covering and fixing magnetic yoke on magnetic core to complete fabrication of iron core. Advantages are: only two dies needed; middle cutting method adopted reduces waste of silicon steel plates, saves raw materials, and lowers fabricating cost; according to number of silicon steel block length of band saw is selectable so as to raise fabricating efficiency, ensure quality of product, and increases economic efficiency.
Description
Technical field
The present invention relates to the making of transformer, ballast, more particularly, relate to a kind of manufacture method of ballast iron core.
Background technology
Traditional transformer, the iron core of ballast becomes " " by the thin silicon steel plates of 0.3-0.5 millimeter through the processing punching out, folded system such as " III " different shape forms, the fabrication of iron core technology of this structure is simple, with low cost, but because this iron core can't encase the coil that twines on the magnetic core, so produce the free more of the magnetic line of force, can't form the loop, and silicon steel sheet absorbs the face of the magnetic line of force at disconnected tangent plane, the planar side magnetic resistance of silicon steel sheet is very big, make iron core can't absorb the free magnetic line of force, so adopt the iron core of the silicon steel plate packing of traditional laminated structure can reduce transformer, the magnetic effect of ballast.Therefore need to make cruciform shaped core, this iron core can encase coil and form four magnetic loops, and the stem stem face of iron core is disconnected tangent plane, and the stem stem that makes can fully absorb the magnetic line of force, improves the magnetic effect of transformer, ballast.
General at present employing mould punching one-tenth "
-" method of folded system is made ballast iron core behind type book silicon steel sheet and " " type book silicon steel sheet.See also shown in Figure 1, each "
-" width of type book silicon steel sheet 101 do not wait, when the width difference of an end parts of each " " type silicon steel sheet 102, folded system, with 40 "
-" alignment of type silicon steel sheet 101 1 ends, the other end builds up the silicon steel piece 103 of the prism of 45 degree, and the horizontal cross-section of this silicon steel piece 103 is a right-angled trapezium; With 40 end alignment that " " type silicon steel sheet 102 width are identical, folded system forms " " type silicon steel piece 104 that prism is 45 degree equally; 8 identical horizontal cross-sections silicon steel piece 103 that is right-angled trapezium is intersected phase spell shape across yokes, it is cross magnetic core that 8 identical " " type silicon steel pieces 104 are combined into whole horizontal cross-section by identical method, at last yoke is covered on magnetic core and also fixed, finish fabrication of iron core.Adopt this technology make different in width "
-" type and " " type book silicon steel sheet need open the secondary different moulds of system 80; number of molds that needs is too big; and the silicon steel sheet of punching out different in width can be wasted a lot of silicon steel materials; so cost of manufacture is very high; punching out and folded operation of piecing together are many and numerous and diverse in addition, cause make efficiency low, and are difficult to the smooth of assurance prism with the bloom of the different silicon steel plate packing of multi-disc width; and strengthened the difficulty that the silicon steel piece is pieced together mutually, reduced the quality of product.
Summary of the invention
At exist in the prior art above-mentionedly need that number of molds is big, waste silicon steel material, cost of manufacture height, efficient is low pieces together the high shortcoming of difficulty mutually with the silicon steel piece, the manufacture method that the purpose of this invention is to provide a kind of ballast iron core, this method is simple and convenient, not only silicon steel material can be saved, and make efficiency can also be improved.
For achieving the above object, the present invention adopts following technical scheme:
The step of the manufacture method of this ballast iron core is as follows,
A. with mould punching go out "
-" type thin silicon steel plates and " III " type thin silicon steel plates, with identical shaped thin silicon steel plates folded respectively make certain thickness "

B. to "
-" type silicon steel piece and " III " type silicon steel piece cut, and is cut into two a pieces and two b pieces of symmetry respectively;
C. to be combined into horizontal cross sectional geometry respectively be cross yoke and cross magnetic core with a piece after the cutting among the step B and b piece;
D. yoke is covered on magnetic core and also fixed, finish fabrication of iron core.
Among the described step B,
In when cutting, can with described "
-" type silicon steel piece and " III " type silicon steel piece advance cutting respectively.
Among the described step B,
In when cutting, can with described "
-" type silicon steel piece is arranged on " III " type silicon steel piece, carries out integral cutting.
Among the described step B,
In when cutting, can with a plurality of described "
-" type silicon steel piece and " III " type silicon steel piece discharge side by side, cut simultaneously.
Among the described step B,
When cutting, "
-" be miter angle cutting in the middle of the silicon steel piece and with a ' limit; B ' limit at " III " type thin silicon steel plates mid portion is miter angle cutting.
Among the described step B,
It is right-angled trapezium that described a piece is cut into the horizontal cross-section; It is " " type that described b piece is cut into vertical cross-section.
Among the described step B,
Can use the saponification liquor that adds machine oil to cool off flushing during cutting.
Among the described step C,
C1. eight a pieces after will cutting through step B carry out two two-phases to be pieced together, and forms four horizontal cross-sections and be a part and be right-angled triangle, a part ofly is the c piece of rectangle, and then the cut surface of four c pieces phase spell shape together being become the horizontal cross-section is criss-cross yoke;
C2. will carry out two two-phases through eight b pieces among the step B and piece together, and form four horizontal cross-sections and be a part and be right-angled triangle, a part ofly be the d piece of rectangle, then the cut surface of four d pieces phase spell shape together being become the horizontal cross-section is cross magnetic core.
In technique scheme of the present invention, this method adopt mould punching go out "
-" type thin silicon steel plates and " III " type thin silicon steel plates, with identical shaped thin silicon steel plates folded respectively make certain thickness "
-" type silicon steel piece and " III " type silicon steel piece; To "
-" type silicon steel piece and " III " type silicon steel piece cut, and is cut into two a pieces and two b pieces of symmetry respectively; To be combined into horizontal cross sectional geometry respectively be criss-cross yoke and magnetic core with a piece after the cutting among the step B and b piece; Yoke covered on magnetic core and fixing, finish fabrication of iron core.Adopt this method only to need two moulds, need not to open in addition other moulds of system, the method of cutting has reduced the waste of silicon steel sheet in the middle of adopting, and has saved raw material, reduced cost of manufacture, and band saw can be selected different length with the silicon steel piece that is cut quantity side by side, can cut a plurality of silicon steel pieces simultaneously, has not only improved make efficiency, and guaranteed product quality to have increased economic benefit.
