The invention provides a steel bar pre-bending and shaping device for a steel bar cage, and belongs to the technical field of engineering. The steel bar pre-bending shaping device comprises a rack, a rotating base, a driving device, a winding device, a rotating piece and a pushing mechanism. The driving device is used for driving the rotating base to rotate around the rotating axis. The winding device comprises a driving mechanism and a plurality of winding pieces distributed on the rotating base at intervals in the circumferential direction. The driving mechanism is used for driving the winding pieces to move in the direction close to or away from the rotating axis. The plurality of winding pieces comprise a first winding piece. The rotating piece is axially locked and circumferentially and rotatably arranged on the first winding piece, the rotating piece is provided with a first end deviating from the rotating axis in the axial direction, and a clamping groove is formed in the first end. The pushing mechani
