The invention relates to solid coil iron core electric transformer silicon steel sheet machining equipment. The equipment comprises a base plate; a winding device is mounted on the base plate; an adjusting cutting device is mounted at the middle part of the upper end of the base plate; a cutting auxiliary device is mounted on the base plate; the cutting auxiliary device is mounted rightly above the adjusting cutting device; and the winding device comprises a winding roller, a first tensioning mechanism, a second tensioning mechanism and a winding roller mounted on the base plate in sequence from front to back. The equipment solves the difficulties of weak manual cutting precision of silicon steel sheets by dint of cutting tools in the silicon steel sheet cutting process of a traditional solid coil iron core transformer, influence on the conveying stability of the silicon steel sheets by easy deformation of the wound silicon steel sheets in the cutting and feeding process, need of manual adjustment of the positions of the cutting tools in cutting of the silicon steel sheets with different specifications, influence on the service life of the solid coil iron core transformer by weak precision of manual adjustment of the cutting tools, and the like.
