TECHNICAL FIELD OF THE INVENTION
The present invention relates to a glass sheet cooling device and a glass sheet quenching and strengthening method for supplying cooling air for quenching and strengthening a glass sheet.
本発明は上記従来技術を考慮したものであって、ノズル孔部分の圧力損失を低く抑えて冷却効率の向上を図り急冷強化作用を高めたガラス板の冷却装置およびガラス板の急冷強化方法の提供を目的とする。 The present invention has been made in consideration of the above-described conventional technology, and provides a glass sheet cooling apparatus and a glass sheet quenching and strengthening method which improve the cooling efficiency by suppressing the pressure loss in the nozzle hole portion to be low and improve the quenching and strengthening action. With the goal.
この構成によれば、鋸歯状のブロック部材の歯の側面で構成されるほぼＶ形状の案内面に沿ってその底部のノズル孔に向かって冷却風がガイドされ、冷却風の流れが円滑になって圧力損失が小さくなる。
また本発明では、ガラス板を曲げ成形温度まで加熱する工程と、前記ガラス板を請求項１〜３のいずれかに記載のガラス板の冷却装置に搬送する工程と、前記ガラス板の冷却装置に設けられたノズル孔から前記ガラス板に向けて冷却風を噴出する工程とを含むガラス板の急冷強化方法を提供する。この構成によれば、急冷強化作用を高めたガラス板の急冷強化が可能となる。
According to this configuration, the cooling air is guided toward the nozzle hole at the bottom along the substantially V-shaped guide surface formed by the side surfaces of the teeth of the sawtooth-shaped block member, so that the flow of the cooling air is smooth. Pressure loss is reduced.
Further, in the present invention, a step of heating the glass sheet to a bending temperature, a step of transporting the glass sheet to the glass sheet cooling device according to any one of claims 1 to 3, and the glass sheet cooling device. A step of injecting cooling air from the provided nozzle hole toward the glass sheet. According to this configuration, rapid cooling and strengthening of the glass sheet with enhanced rapid cooling effect can be achieved.
