Gradually-moulding bended tempered glass radian-changing device

Abstract

The invention discloses a gradually-moulding bended tempered glass radian-changing device, which includes a plurality of supporting beams which are extended longitudinally and are arranged transversally at intervals. A plurality of cooling air grates and a plurality of support roller wheels are arranged on the supporting beams longitudinally at intervals. The two ends of the supporting beams are connected to two transversal radian-changing mechanisms respectively through universal ball pairs. The two transversally radian-changing mechanisms can change the radian according to the radian-changing settings respectively, so that the two longitudinal ends of a glass plate, which is conveyed to the support roller wheels, are bended according to different curvatures, wherein the longitudinal direction is the movement direction of the glass while the transversal direction is vertical to the movement direction of the glass. By means of the device, glass can be bended when the glass is discharged from a furnace, so that it is unnecessary to wait the glass to be discharged completely, thereby saving production time. When long bended tempered glass needs to be processed, the device can avoid the quality defect caused by different temperature at the head and the tail of the glass during bending. By means of independent control on the transversally radian-changing mechanisms, special-shaped glass of which the bending radian is not constant can be processed on the device.

Description

[0001] technical field [0002] The invention relates to a glass bending and arc changing equipment used in a bending tempered glass production line. [0003] Background technique [0004] 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 ...

Problems solved by technology

[0007] 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 act 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 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
