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 become through the processing punching out by the thin silicon steel plates of 0.3-0.5 millimeter
, the folded system of different shape such as " Ш " 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 the face that silicon steel sheet absorbs the magnetic line of force is 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 the magnetic effect of transformer, 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.
The general at present mould punching that adopts becomes "-" type book silicon steel sheet and falls
The method of folded system is made ballast iron core behind the type book silicon steel sheet.See also shown in Figure 1ly, the width of each "-" type book silicon steel sheet 101 does not wait, and each falls
The width difference of one end parts of type silicon steel sheet 102, during folded the system, with 40 "-" type silicon steel sheet 101 1 ends alignment, the other end builds up the silicon steel piece 103 of the prisms of 45 degree, and the horizontal cross-section of this silicon steel piece 103 is a right-angled trapezium; Equally 40 are fallen
It is falling of 45 degree that the end alignment that type silicon steel sheet 102 width are identical, folded system form prism
Type silicon steel piece 104; 8 identical horizontal cross-sections silicon steel piece 103 that is right-angled trapezium is intersected phase spell shape across yokes, with 8 identical falling
It is cross magnetic core that type silicon steel piece 104 is combined into whole horizontal cross-section by identical method, at last yoke is covered on magnetic core also to fix, and finishes fabrication of iron core."-" type and the type that adopt this technology to make different in width fall
Type book silicon steel sheet need be opened the different mould of system 80 pairs, the 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, therefore 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 guarantee the smooth of 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. go out "-" type thin silicon steel plates and " Ш " type thin silicon steel plates with mould punching, with folded respectively certain thickness "-" type silicon steel piece and " Ш " type silicon steel piece made of identical shaped thin silicon steel plates;
B. "-" type silicon steel piece and " Ш " type silicon steel piece are cut, be cut into two a pieces and two b pieces of symmetry respectively;
C. to be combined into horizontal cross sectional geometry respectively be criss-cross yoke and criss-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,
When cutting, described "-" type silicon steel piece and " Ш " type silicon steel piece can be cut respectively.
Among the described step B,
When cutting, described "-" type silicon steel piece can be arranged on " Ш " type silicon steel piece, carry out integral cutting.
Among the described step B,
When cutting, a plurality of described "-" type silicon steel piece and " Ш " type silicon steel piece can be discharged side by side, cut simultaneously.
Among the described step B,
When cutting, in the middle of the long limit of "-" silicon steel piece, be miter angle cutting; In the middle of the long limit of " Ш " type thin silicon steel plates mid portion, be miter angle cutting.
Among the described step B,
It is right-angled trapezium that described a piece is cut into the horizontal cross-section; Described b piece is cut into vertical cross-section for falling
Type.
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 adopts mould punching to go out "-" type thin silicon steel plates and " Ш " type thin silicon steel plates, with folded respectively certain thickness "-" type silicon steel piece and " Ш " type silicon steel piece made of identical shaped thin silicon steel plates; "-" type silicon steel piece and " Ш " type silicon steel piece are cut, be 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.
