1. A forming apparatus for curved tempered glass, comprising a frame, a gradual transition section, an air grid system, and a forming system, wherein:
the air grid system comprises an upper air grid group comprising a plurality of upper air grids, and a lower air grid group comprising a plurality of lower air grids;
the upper air grid group is mounted at an upper half of the frame, and the lower air grid group is mounted at a lower half of the frame;
the gradual transition section is arranged at an inlet side of the forming system;
the gradual transition section comprises a plurality of transitional transverse arching mechanisms arranged in a glass pane conveying direction to enable a glass pane to be gradually arched in a transverse direction, and the gradually arched glass pane is conveyed into the forming system;
the forming system comprises two groups of longitudinal forming and arching mechanisms and a plurality of transverse forming and arching mechanisms arranged in the glass pane conveying direction;
the longitudinal forming and arching mechanisms are controlled by a lower arching mechanism to perform longitudinal curve forming on the glass pane in the forming system; the transverse forming and arching mechanisms are connected to the longitudinal forming and arching mechanisms through a lower support cross beam to perform transverse curve forming on the glass pane in the forming system;
the transverse forming and arching mechanism comprises a first elastic piece, a first plurality of height adjustment mechanisms and a first glass conveying mechanism mounted on the first elastic piece; a center position or a middle section of the first elastic piece in a lengthwise direction is fixed on the lower support cross beam; two sides of the center position or the middle section are connected to the lower support cross beam through the first plurality of height adjustment mechanisms; the first elastic piece is arched by adjusting the first plurality of height adjustment mechanisms; and
the lower air grid is composed of a plurality of lower air blowing boxes; the plurality of lower air blowing boxes are arranged between adjacent transverse forming and arching mechanisms in the lengthwise direction of the first elastic piece; the lower air blowing boxes are mounted on the first elastic piece, so that the lower air blowing boxes act with arching actions of the transverse forming and arching mechanisms and the longitudinal forming and arching mechanisms.
