Abstract

The utility model discloses a type-I silicon steel sheet laminated riveting structure of an electromagnetic ballast. The type-I silicon steel sheet laminated riveting structure comprises silicon steel sheet bodies, and at least two protruded points protruded downwards are punched on each silicon steel sheet body. Grooves recessed towards the direction of the protruded points are arranged on the other sides of the protruded points, and the protruded points and the grooves are arranged at the same position of each silicon steel sheet body and enable the overlaid silicon steel sheet bodies to be stacked tidily. The type-I silicon steel sheet laminated riveting structure has the advantages that by enabling at least two protruded points protruded downwards to be punched at the same position of each silicon steel sheet body, when a plurality of silicon steel sheets are overlaid, the protruded points can be utilized to perform positioning, whole tilt is avoided. Simultaneously, the arranged grooves can reduce intervals between the silicon steel sheets, the integral shape of the stacked silicon steel sheets is improved, not only is attractiveness effect improved, but also riveted efficiency is also improved, and riveting quality is improved.

Description

Inductive ballast I type silicon steel sheet is folded the riveting knot structure

Technical field

The utility model relates to the folded riveting knot structure of a kind of Inductive ballast I type silicon steel sheet.

Background technology

The used silicon steel sheet of existing Inductive ballast is EI type silicon steel sheet, silicon steel sheet installation at ballast makes and the I matrix need to be embedded in the E matrix, and at least will be with assembling behind the silicon steel sheet closed assembly more than 100 in ballast, because ballast is with needing certain magnitude of interference between E type silicon steel sheet and the I type silicon steel sheet, although so assemble special tooling by existing technique, but 100 multi-disc I sheets to be put in the E sheet and still be had a lot of problems, relatively distinct issues have: efficient is low, between sheet and the sheet gap appears, the whole crooked phenomenon etc. that occurs.

Summary of the invention

The technical problems to be solved in the utility model provides and a kind ofly can improve riveted joint efficient, improves the folded riveting knot structure of Inductive ballast I type silicon steel sheet of riveting quality.

In order to solve the problems of the technologies described above, Inductive ballast I type silicon steel sheet of the present utility model is folded the riveting knot structure, comprise the silicon steel sheet body, there are two to the salient point of lower convexity to Shaochong on every a slice silicon steel sheet body, the another side of salient point is the groove to salient point direction depression, and salient point is arranged on the identical position of every a slice silicon steel sheet body with groove and the silicon steel sheet body of each sheet stack can neatly be stacked.

The utility model has the advantage of:

There are two to the salient point of lower convexity by identical position to Shaochong on every a slice silicon steel sheet body, when the multi-disc silicon steel sheet stacks, can utilize salient point to position, avoided thus the crooked situation of whole appearance, the groove that arranges simultaneously can reduce the gap between the every silicon steel sheet, make that the silicon steel sheet that stacks is moulded to be improved, not only improved aesthetic and also improved the efficient of riveted joint, improved riveting quality.

Embodiment

Below in conjunction with the drawings and specific embodiments, the folded riveting knot structure of Inductive ballast I type silicon steel sheet of the present utility model is described in further details.

As shown in the figure, Inductive ballast I type silicon steel sheet of the present utility model is folded the riveting knot structure, comprise silicon steel sheet body 1, there are two to the salient point 2 of lower convexity to Shaochong on every a slice silicon steel sheet body 1, the another side of salient point 2 is the groove 3 to salient point direction depression, and salient point 2 and groove 3 are arranged on the identical position of every a slice silicon steel sheet body 1 and the silicon steel sheet body 1 that each sheet is superposeed can neatly stack.

Claims

1. an Inductive ballast I type silicon steel sheet is folded the riveting knot structure, comprise silicon steel sheet body (1), it is characterized in that: described every a slice silicon steel sheet body (1) is upper to have two salient points to lower convexity (2) to Shaochong, the another side of salient point (2) is the groove (3) to salient point direction depression, and described salient point (2) is arranged on the identical position of every a slice silicon steel sheet body (1) with groove (3) and the silicon steel sheet body (1) of each sheet stack can neatly be stacked.
