The invention discloses stamping and overturning equipment for processing environment-friendly new energy building plates. The stamping and overturning equipment comprises a rack, the rack is providedwith an overturning device, and the overturning device comprises a horizontal sliding groove and a vertical sliding groove which are fixed to the rack; a guiding bracket is slidably arranged on the horizontal sliding groove, a first sliding block is arranged on the vertical sliding groove, a fourth shaft frame is arranged on the first sliding block, an overturning shaft is arranged on the fourthshaft frame in the horizontal direction, and the overturning shaft is perpendicular to the length direction of the horizontal sliding groove; an overturning frame is arranged at the end, facing the guiding bracket, of the overturning shaft and comprises an overturning head used for fixing or loosening the steel plates, and two guiding columns; and the guiding columns are rotatably arranged on theoverturning frame, and a isosceles triangle is formed by the connecting lines of the three points of the overturning head and the two guiding columns. The overturning device of the stamping and overturning equipment is reasonable in structural design, the overturning operation of the steel plates can be achieved during up-down reciprocating sliding of the first sliding block, the mechanical structure is high in reliability, the manufacturing cost is low, and maintenance is easy.
