A Gradual Bending Tempered Glass Arc Changing Equipment

Abstract

The invention discloses a gradually shaped curved tempered glass arc changing device. The arc changing device includes several support beams extending longitudinally and arranged at intervals in the transverse direction. The support beams are provided with several cooling air grids and supporting rollers at intervals along the longitudinal direction. The two ends of the support beam are respectively connected to the two transverse arc-changing mechanisms through the universal ball pair; the two transverse arc-changing mechanisms can change the arc according to their respective arc-changing settings, and thus can transfer the The longitudinal ends of the glass plate are bent according to different curvatures; the longitudinal direction is the glass movement direction, and the transverse direction is the vertical glass movement direction. 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 all the glass to be 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 end and the end of the glass during bending Defects; independent control of the horizontal variable arc unit, it 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, no need to wait for the whole glass to be out of the furnace before bending, effectively avoiding the temperature drop when the glass is bent and deformed, resulting in glass bending crack defects. At the same time, the traditional large air grid is made into several small cooling air grids, and The cooling air grid is installed on the support beam, so that the air grid changes with the position of the support beam, ensuring that the glass is evenly winded after bending
