Embodiment Construction

[0017] Such as figure 1 As shown, a kind of hot-bending shaped glass disclosed by the present invention has a hypotenuse 1 on any surface of the arc edge of the glass, such as figure 2 As shown, a hypotenuse 1 can be formed on the upper and lower surfaces respectively, and as image 3 As shown, it can be only a hypotenuse 1 formed on the upper surface, or as Figure 4 As shown, only one hypotenuse 1 may be formed on the lower surface.

[0018] The glass used for hot bending can be single glass, insulating glass or laminated composite glass, with a thickness of 5mm-25mm and a width of 5mm-100mm corresponding to the hypotenuse. The thicker the glass, the wider the width of the hypotenuse 1.

[0019] Since any surface of the arc edge of the glass has a hypotenuse 1, it can overcome the defects of excessive stress concentration caused by extrusion of the edge during the forming process, thereby causing cracks and breakage of the glass. Therefore, it can be applied to thicker h...

Abstract

The invention discloses hot bending reinforced glass. Any surface (an upper surface, a lower surface or both the upper surface and the lower surface) at the arc edge of the glass is provided with a bevel edge. The thickness of the glass is 5 mm to 25 mm and the width of the bevel edge is 5 mm to 100 mm. The glass can be single-pane glass, hollow glass or laminated composite glass. A processing method of the hot bending glass comprises the following steps: firstly, preprocessing the edge to be bended into an arc edge; processing any surface (the upper surface, the lower surface or both the upper surface and the lower surface) at the arc edge of the glass to form a bevel edge; and finally conducting hot treatment processing. The invention solves the problem that the arc edge of the prior artis easily cracked and even damaged during the hot treatment forming of the glass.

Description

technical field [0001] The invention relates to the field of glass processing, in particular to a heat-bending reinforced glass and a processing method of the heat-bending formed glass. Background technique [0002] The purpose of ordinary glass processing is mainly to prevent cuts, achieve beautiful appearance, and meet heat treatment requirements. Reinforced glass formed by hot bending generally includes semi-tempered glass, tempered glass and super-strengthened glass. The heat treatment mainly considers the expansion of micro-cracks at the edge of the glass to cause cracks to spread. When the glass enters a high-temperature environment, these micro-cracks will be rapidly accelerated Expansion leads to breakage, so currently heat-treated safety glass is mainly tempered glass. [0003] Through long-term and large-scale production experience and experimental data, the present inventors have found that during the bending process of glass after heat treatment, if the designed...
