Abstract
The related manufacture method for an amorphous iron core comprises: directly, cutting the left/right side iron core feet of the outer core and left/right inner core respectively at one time to stack and form a left foot, a right foot and a central foot; placing the left and right feet on two sides of the central foot and joining with each other. Compared with the prior art, this invention can simplify the process and reduces cost indeed.
Description
Technical field
The invention relates to a kind of manufacture method of amorphous iron core, refer to a kind of manufacture method that is applicable to the amorphous iron core of transformer inside especially.
Background technology
Because the more traditional core material silicon steel sheet of amorphous iron core material processing procedure is more simplified, consume the lower energy, and it has the soft magnetic property of similar noncrystalline atomic structure and excellent low iron loss, therefore, amorphous iron core transformer with the manufacturing of amorphous iron core material, have environmental protection, economize the characteristic of the energy, be extensive use of with the transformer of silicon steel material made so replace tradition gradually.
Amorphous iron core structure in general transformer, be outside one, to put side by side in the iron core two inner iron cores to be arranged and form so-called three-phase tripod iron core, and traditional manufacturing process is the left side iron core of cutting at first respectively and two inner iron cores of stack, and then the right side iron core of two inner iron cores of cutting.After aforementioned activities is finished, the outer unshakable in one's determination left iron core of cutting, the outer right-hand iron core unshakable in one's determination of cutting then again.
After cutting is finished, make up earlier two inner iron cores respectively, be about to that the left side is unshakable in one's determination and dock after the right side iron core is bent into the U font respectively and to form two little loops of rectangle, and then combination is outer unshakable in one's determination, is about to that its left is unshakable in one's determination and dock after right-hand iron core is bent into the U font respectively and to form a big loop of rectangle.After joint is finished, earlier two inner iron cores are annealed, and then carry out outer annealing unshakable in one's determination.After annealing is finished, then earlier two inner iron cores are tested, and then carried out outer test unshakable in one's determination.At last, make up two inner iron cores earlier and make it side by side, and then put into outer iron core.
From the above, the cutting inside and outside unshakable in one's determination and the combination process of traditional three-phase tripod amorphous iron core are very complicated, for man-hour and cost, all produce certain expending, and too much because of manufacturing process, also can't be improved for the quality of amorphous iron core, real imperfect.
Summary of the invention
The object of the present invention is to provide a kind of manufacture method of amorphous iron core.Manufacture method of the present invention compared to tradition separate the many one-sided iron cores of group of cutting and stack and make up inner iron core, with the practice of outer iron core, can simplify its manufacturing process really, and can reduce its worker the time and cost.
For achieving the above object, the manufacture method of amorphous iron core provided by the invention comprises the following steps:
Steps A: cut out plural pieces amorphous iron core sheet, and will be wherein a part of stack become a left pin unshakable in one's determination, another closes a part stack and becomes left side pin unshakable in one's determination, wherein, this left side pin unshakable in one's determination is longer than this left side pin unshakable in one's determination, and pin should a left side unshakable in one's determination lies alongside one another with this left side pin unshakable in one's determination, and bend this left side iron core pin and this left side pin unshakable in one's determination make its towards this left side pin one lateral bending song unshakable in one's determination and form a left side pin;
Step B: cut out plural pieces amorphous iron core sheet, and wherein a part of stack becomes a right pin unshakable in one's determination, another part stack to become a right-hand pin unshakable in one's determination, wherein, this right side pin unshakable in one's determination is longer than this right-hand pin unshakable in one's determination, and pin should the right side unshakable in one's determination lies alongside one another with this right-hand pin unshakable in one's determination, and bends this right side pin unshakable in one's determination and make it form a right side pin towards this right-hand pin one lateral bending song unshakable in one's determination with this right-hand pin unshakable in one's determination;
Step C: cut out plural pieces amorphous iron core sheet, and wherein a part of stack becomes right side pin unshakable in one's determination, another part stack to become left pin unshakable in one's determination, and this right side pin unshakable in one's determination and this left pin unshakable in one's determination lain alongside one another, and bend this right side pin unshakable in one's determination respectively and make it form a crura intermedium towards opposite two lateral bendings song respectively with this left iron core pin;
Step D: put this left side pin, also dock mutually in two sides of this crura intermedium with this right side pin, and this left side of superimposed arrangement pin unshakable in one's determination, form with the amorphous iron core sheet of this right side pin unshakable in one's determination one outer unshakable in one's determination, and this left side of superimposed arrangement pin unshakable in one's determination, form a left inner iron core, and this left of superimposed arrangement pin unshakable in one's determination, form a right inner iron core with the amorphous iron core sheet of this right-hand pin unshakable in one's determination with the amorphous iron core sheet of this right side pin unshakable in one's determination; And
Step e: annealing should outer iron core, this left side inner iron core, with this right side inner iron core.
Wherein also include a step F: test should outer iron core, this left side inner iron core, with this right side inner iron core.
Wherein in this step F, be to test this outer iron core, this left side inner iron core, and this right side inner iron core respectively with an iron loss tester.
Wherein in this step e, be after joint is finished should outer iron core, this left side inner iron core, be positioned over one with this right side inner iron core and anneal and anneal on the chassis.
Wherein be somebody's turn to do outer iron core, this left side inner iron core, be placed in the transformer with this right side inner iron core.
By above-mentioned steps as can be known, the present invention directly cuts out plural pieces amorphous iron core sheet and is overlapped into left side pin, right side pin and crura intermedium, also can directly carry out left side pin, right side pin, with the cutting of crura intermedium and superimposed, afterwards and directly it is put and superimposed outer iron core, left inner iron core, and the right inner iron core of being organized into, so compared to tradition separately plant cut and make up inner iron core, with the practice of outer iron core, the present invention can simplify its manufacturing process really, and can reduce its worker the time and cost.That is from the above, the present invention is different with the mode that traditional inside and outside iron core separates cutting and combination, i.e. the present invention is divided into three part cuttings processing with iron core, and becomes left side pin, right side pin and crura intermedium, its combination is got final product at last again.
