The invention discloses a feeding and finishing device before stamping and stacking stator sheets, which comprises a feeding bracket, a loading device and a finishing device. The stator blanking pieceis annular and has several superposed limiting grooves circumferentially and uniformly distributed and formed in the outer cylinder surface. The feeding bracket comprises a feeding tank body arrangedobliquely downward; a rotary support groove is formed in the lower end outlet of the feeding tank body; a load device is detachably arranged on the lower end surface of the rotary support groove; theload device comprises a loading support plate; a plurality of fixed support blocks uniformly distributed around the circumference are formed on the downloading material support plate; a plurality ofinsertion support blocks uniformly distributed in the circumference are vertically inserted from the top to the bottom in the downloading material support plate. The fixed limit block and the insertion limit block fitting with the overlapping limit grooves are respectively formed on the fixed support block and the insertion support block; the finishing device is used for driving the stator punching sheet to rotate. The invention has the advantages of automatic feeding and finishing after the stator punched sheet is formed and convenient transportation after the finishing, greatly reducing thehuman expenditure and improving the working efficiency.
