Claim 14:
15. A forming method for multi-curved-surface tempered glass, wherein:
a forming apparatus used by the forming method comprises a frame, a gradual transition section, a forming system, and an air grid system;
the gradual transition section is arranged at an inlet side of the forming system, and comprises a plurality of transitional transverse arching mechanisms arranged in a glass pane conveying direction;
the forming system comprises a plurality of transverse forming and arching mechanisms arranged in the glass pane conveying direction and two groups of longitudinal forming and arching mechanisms;
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; and
the forming method comprises:
adjusting the transitional transverse arching mechanisms in the gradual transition section and the transverse forming and arching mechanisms in the forming system to desired positions according to a radian requirement for glass to be formed in a transverse direction, and adjusting upper air grid transverse arching mechanisms and upper air grid longitudinal arching mechanisms of the upper air grid group to desired positions according to radian requirements of a glass pane to be formed in the transverse direction and a longitudinal direction;
making the glass pane heated to a softened state leave a heating furnace and enter the gradual transition section to complete transverse gradual preforming of the glass pane;
making the glass pane enter the forming system from the gradual transition section for transverse curve forming under the gravity;
pulling two ends of the longitudinal forming and arching mechanisms to desired positions to make the glass pane complete longitudinal curve forming;
making the glass pane completing the transverse and longitudinal curve forming move in the forming system in a reciprocating manner, and making the upper air grid group and the lower air grid group blow air to cool the glass pane to complete tempering; and
pulling the two ends of the longitudinal forming and arching mechanisms to horizontal positions, lifting the upper air grid group to a set height through a lifting mechanism, and conveying the tempered glass pane out of the forming system, wherein:
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 an elastic piece, a plurality of height adjustment mechanisms and a glass conveying mechanism mounted on the elastic piece;
a center position or a middle section of the 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 plurality of height adjustment mechanisms;
the elastic piece is arched by adjusting the plurality of height adjustment mechanisms;
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 elastic piece; and
the lower air blowing boxes are mounted on the 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.
