Air grid used for toughening of curved glass

Abstract

The invention discloses an air grid used for toughening of curved glass. The air grid comprises an upper air grid and a lower air grid which are arranged up and down, the upper air grid is provided with an upper air cavity for installing upper air boxes, the lower air grid is provided with a lower air cavity for installing lower air boxes, a plurality of upper air boxes are arranged on the lower surface of the upper air cavity at intervals in the glass conveying direction, each upper air box is provided with an air blowing face with a shape matched with that of the upper surface of curved glass to be formed, and upper air holes are arranged in each air blowing face; a plurality of lower air boxes are arranged on the upper surface of the lower air cavity at intervals in the glass conveyingdirection, each lower air box is provided with an air blowing face with a shape matched with that of the lower surface of the curved glass to be formed, and lower air holes are distributed in each airblowing face; and the upper air boxes and the lower air boxes are correspondingly arranged up and down. The curved glass can be uniformly subjected to wind in the air grid provided by the invention,and the surface quality of the glass is improved.

Description

technical field [0001] The invention belongs to curved glass tempering forming equipment in the field of glass deep processing, and in particular relates to an air grid for tempering curved glass. Background technique [0002] During the tempering process of glass, air grid cooling also has a great influence on the quality of tempered glass. This is especially true for curved tempered glass. For curved tempered glass, because the glass is bent and deformed, in order to ensure that each air grille and the glass surface can maintain the same distance when the air grill blows, the air grilles also need to be connected to the corresponding arc-changing mechanism, which will increase the tempered glass forming equipment. Structural complexity, and in the actual control process, it is also more complicated. [0003] According to the definition of a curved surface, a curved surface can be regarded as a trajectory formed by a moving line (straight line or curve) moving continuousl...

Problems solved by technology

For this kind of curved glass, it is difficult for the variable arc air grille of conventional tempering equipment to completely surround the glass, and it is also difficult to adjust the air grille to a position equal to the distance from the glass surface. etc., and in the wind grille, some positions on the glass surface are always blown by wind, while some positions are never blown by wind, which makes the glass surface cooled unevenly by the wind, thus easily causing wind spots and affecting the quality of the glass
