Method for adjusting bent air grid of parallel bent toughening furnace

Abstract

The invention relates to a method for adjusting a bent air grid of a parallel bent toughening furnace and belongs to the technical field of glass machining. The method comprises adjustment of a lower air grid and adjustment of an upper air grid. In the adjustment of the lower air grid, a template is arranged between the lower air grid and the upper air grid, and one side of the template is a plane and the opposite side of the template is a cambered surface the radius of which is same with the theoretical radius of bent toughened glass, the plane is fixed on a support plate, and the lower air grid is fixed on the cambered surface. In the invention, the template with the cambered surface the radius of which is same with the theoretical radius of the bent toughened glass is made, and the lower air grid is fixed on the curved surface of the template, so that the adjustment of the whole bent air grid becomes simple and can be easily controlled; and the bent toughened glass produced by the invention has radian same with the template with standard radius, quite attractive appearance and good absolute curvature tolerance among the bent toughened glass; for the bent toughened glass with different curvatures, users only needs to change different templates, which can be realized quite easily.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a method for adjusting a curved air grid of a parallel curved tempering furnace. Background technique [0002] In the parallel curved tempering furnace equipment at home and abroad, the two ends of the curved air grid are variable arc dragon structures. When producing curved tempered glass, firstly adjust the arc of the upper and lower air grids in the forming section according to the required theoretical radius, and set the parameters After the glass is heated, quickly enter the curved air grille according to the set parameters, land on the adjusted lower air grille, and then quickly change the arc. At this time, the formed upper air grille has been adjusted and directly falls to the set set height. The bending and tempering of the glass is achieved through the arc adjusted by the variable arc dragon structure of the lower and upper air grilles. figure 1 , figure 2 ...

AI Technical Summary

Problems solved by technology

The bending and tempering of the glass is achieved through the arc adjusted by the variable arc dragon structure of the lower and upper air grilles. figure 1 , figure 2 As shown, as shown in Chinese patent ZL200410062528.8, the variable arc dragon adjustable nut is used to form the required single curved surface, and the height of the nuts at each point can be adjusted to form a single curved surface with different radii. The theoretical radius of the tempered glass is consistent, but it is very difficult to calculate and adjust the height of the chameleon nut. If the adjustment is not in place, it is easy to make the curvature of the single side of the glass curved and tempered incomplete, and the appearance is poor. , especially for the bending and tempering of super-large-format glass and the curvature of large radius. In the center of the layout, because the adjustment of the dot matrix height is not much different, if the error control is not good, it is easy to form a flat center and curved sides. If you want to If several pieces of bent tempered glass are interlayered, the absolute matching degree of different bent tempered glass cannot be guaranteed. Therefore, in the process of bent tempered glass, the adjustment and setting of the bent air grille are very important.
