Silicon-steel sheet longitudinal-shearing guiding device used for transformer

The utility model provides a silicon-steel sheet longitudinal-shearing guiding device used for a transformer. The guiding device is used for guiding the feeding of a silicon-steel sheet of a longitudinal shear and comprises a guide rail group and a bakelite plate, wherein the guide rail group is arranged on the bakelite plate; the guide rail group comprises a first guide rail and a second guide rail which are symmetric; the first guide rail is arranged in parallel to the second guide rail; a slideway used for conveying the silicon-steel sheet is arranged between the first guide rail and the second guide rail; at least three pairs of roller bearings are arranged on the first guide rail and the second guide rail; and the peripheries of the roller bearings extend in the slideway. In the utility model, as a plurality of roller bearings are arranged in the slideway that is formed between the first guide rail and the second guide rail, the curving degree of an S curve of the silicon-steel sheet can be conveniently
