Summary of the invention
The purpose of the utility model provides a kind of silicon sheet core of riveted joint certainly that assembles the iron core good electrical property quick, that the assembling back forms.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of from riveting silicon sheet core; Form by the some overlapping riveted joints of silicon steel sheet; Described silicon steel sheet is for rivet silicon steel sheet certainly; Described have opposite first and second surface from riveting silicon steel sheet; Described have the riveted joint button from riveting on the silicon steel sheet to dash, described riveted joint button comprise be formed on the described first surface and indent in the first riveted joint face of described first surface, be formed on the described second surface and evagination in the second riveted joint face of described second surface, the described first riveted joint face surrounds the groove of indent in described first surface; The described second riveted joint face surrounds the convexity of evagination in described second surface, and the described first riveted joint face is identical with the shape of the described second riveted joint face;
When two described from riveting silicon steel sheet when riveting mutually; First described from the convexity of riveting silicon steel sheet snap in second described from riveting in the groove of silicon steel sheet, first described first riveted joint face from the riveted joint silicon steel sheet is adjacent to mutually with second described second riveted joint face from the riveted joint silicon steel sheet and two describedly engaged from riveting silicon steel sheets.
Preferably, described groove is arc column, its string plane and the described first plane flush.
Preferably, the arc column of described convexity for matching with described groove.
Preferably, described have a plurality of described riveted joint buttons from rivet to dash on the silicon steel sheet symmetrically.
Preferably, the described riveted joint certainly also offers a plurality of riveted holes on the silicon steel sheet.
Preferably, describedly be " day " font from riveting silicon steel sheet, it comprises first connecting portion and second connecting portion at both ends of two side column sheets that are arranged at described center pillar sheet both sides, the described center pillar sheet of connection and the described side column sheet of center pillar sheet, symmetry; On described center pillar sheet, described side column sheet, described first connecting portion, described second connecting portion all towards described riveted joint button is arranged.
Because the technique scheme utilization, the utility model compared with prior art has advantage: because the iron core of the utility model adopts the silicon steel sheet riveted joint with riveted joint button to form, convenient and swift when assembling; And iron core surfacing, electrical property consistency after the assembling are good.
