A Gradual Bending Tempered Glass Arc Changing Equipment

Abstract

The invention discloses an arc-changing equipment for curved tempered glass with a gradual shape, which comprises several support beams extending longitudinally and arranged at intervals in the transverse direction. The support beams are provided with several cooling air grids and support rollers at intervals along the longitudinal direction. One end is connected to a transverse arc-changing mechanism through a universal ball pair, and the other end of the support beam is hinged to another transverse arc-changing mechanism through a pin shaft extending horizontally; the two transverse arc-changing mechanisms can be set according to their respective arc changes to change the arc. The invention can realize that the glass can be bent as soon as it comes out of the furnace, and there is no need to wait for the glass to be completely out of the furnace before starting to bend, which saves production time; when processing longer curved tempered glass, there will be no quality problems caused by the temperature difference between the head and the tail of the glass during bending Defects; independent control of the horizontal variable arc unit can also process special-shaped glass with non-uniform curvature.

Description

technical field [0001] The invention relates to a glass bending and arc changing equipment used in a bending tempered glass production line. Background technique [0002] Currently, if figure 1 As shown, the curved tempered glass production line mainly includes a loading table 1, a heating furnace 2, a cooling and tempering device 3 and an unloading table 4, and an air grid and an arc-changing mechanism are arranged in the cooling and tempering device 3. The traditional processing method is that the glass is loaded on the loading table 1, the heating furnace 2 heats the glass, and the heated glass is sent to the cooling and tempering device 3, and is first bent and deformed by the arc-changing mechanism, and then cooled by the air grid Tempered and cooled glass is unloaded on unloading table 4. When the glass is bent and deformed, it must wait for the glass to completely enter the cooling and tempering device before proceeding. The disadvantage of this traditional process...

Problems solved by technology

[0004] Aiming at the problems existing in the production of curved tempered glass in the prior art, especially in the production of large-sized curved tempered glass, the inventors of the present invention provide a feasible gradual shape according to the concept of pre-formed gradient bending The arc-changing equipment for curved tempered glass, the arc-changing mechanisms at both ends of the arc-changing equipment can operate independently, and can realize the arc-changing at one end of the arc-changing equipment and the straight end at the other end, so that the glass can be bent in advance at the end of the furnace, and the glass can be bent at the same time as it comes out of the furnace. Bending, there is no need to wait for the whole glass to be out of the furnace before bending, which effectively avoids the temperature drop when the glass is bent and deformed, which leads to the problem of glass bending crack defects
