Abstract
The utility model relates to a square tool used for producing transformer cores, in particular to a corner-knocking tool used for a core lamination. According to the technical scheme, a card slot is arranged at the end of a body, one side face of the card slot is a vertical face which is perpendicular to the bottom face of the card slot, and the other side face is provided with a section of inclined face close to a notch of the card slot so as to lead one section of the card slot close to the bottom face to be rectangular and lead one section close to the notch to be trumpet-shaped extending outward. The corner-knocking tool can improve the lamination precision of a silicon steel sheet.
Description
Technical field
The utility model relates to a kind of square utensil of producing transformer core, specifically a kind of be used for core lamination strike the hornwork tool.
Background technology
When producing transformer, iron core need be carried out closed assembly according to the requirement of setting, during operation, with the silicon steel sheet cut out piecewise stack to predetermined quantity.Because the quantity of stack is many, if in the stack process, silicon steel sheet is irregular, can have influence on the quality of transformer, and therefore, all fitly stack is together on request must to guarantee all silicon steel sheets.In the prior art, owing to do not strike the hornwork tool accordingly, often cause the bight of all silicon steel sheets uneven.
Summary of the invention
The purpose of this utility model be to design a kind of be used for core lamination strike the hornwork tool, to improve the lamination precision of silicon steel sheet.
The technical scheme that provides according to the utility model, end at body is provided with draw-in groove, a side of described draw-in groove is the facade vertical with the bottom surface of draw-in groove, there is one section inclined-plane at the position of the notch of close draw-in groove on another side, make described draw-in groove rectangular near a section of bottom surface, near one section one-tenth of notch expand outwardly tubaeform.
The inclination angle on described inclined-plane is 45 degree.
Because being centralized positioning laminated layer method and centralized positioning mould, the present invention determines that originally do not adopt positioning module, this positioning module is along with the invention of centralized positioning laminated layer method is invented.This invention can guarantee the evenness of each end face of lamination, and the angle of departure of stepping lamination is unified and uniform, effectively guarantees the dimensional accuracy of each section unshakable in one's determination, and outward appearance can reduce loss unshakable in one's determination simultaneously to guarantee to have preferably by lamination.
This utility model has the following advantages: simple to operate, easy to use; Volume is little, is convenient for carrying; Workable; Can not cause the secondary injury to iron core.
Description of drawings
Fig. 1 is the structural representation of utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure: draw-in groove 3 is set in the end of body 1, a side of described draw-in groove 3 is the facade vertical with the bottom surface of draw-in groove 3, there is one section inclined-plane 2 at the position of the notch of close draw-in groove 3 on another side, make described draw-in groove 3 rectangular near a section of bottom surfaces, near one section one-tenth of notch expand outwardly tubaeform.The inclination angle on described inclined-plane 2 is 45 degree.
The utility model is a frock a kind of simple in structure, easy to make, the equal-sized draw-in groove 3 of angle of departure of setting and silicon steel sheet on frock, and the effect of this draw-in groove 3 is to repair stepping angle of departure unshakable in one's determination and end face unshakable in one's determination.To improve the regularity of stepping angle of departure unshakable in one's determination, using angle error guarantees at ± 0.2mm, the cuboid that the utility model is made into by common iron, the end face of cuboid is smooth, have the draw-in groove 3 of a band angle in the cuboid upper end, the degree of depth of draw-in groove 3 is formulated according to the angle of departure size of iron core, existing six kinds of specifications.According to the size of angle of departure unshakable in one's determination, the degree of depth of draw-in groove 3 also has different size, and the inclination angle on inclined-plane 2 is a definite value 45 degree, matches with the sheet type angle of electrical steel sheet.Inclined-plane 2 is when utilizing this utensil to repair angle of departure unshakable in one's determination, and the angle and the drift angle of protection lamination type are injury-free.During use, the upper surface of this utensil is contacted and the maintenance level with the angle of departure place of iron core, the utensil that hits with a hammer again makes each sheet type unshakable in one's determination reach neat effect.
In the transformer core manufacture process, definite says in the lamination process, because the problem such as skilled of employee's technical ability, regular meeting produces the secondary injury to iron core.Compare with existing closed assembly technology unshakable in one's determination, absolute advantage is arranged on the evenness of angle of departure, remarkable result is arranged improving core loss.Also obviously can enhance productivity simultaneously.
