Description

Technical Field

[0001] The invention relates to the technical field of glass processing, in particular to a curved glass tempering furnace. Background Art

[0002] In contemporary people's lives, the use of tempered glass can be seen everywhere. Existing tempered glass is heated by high-temperature gas and then treated with rapid cooling technology to form compressive stress on the surface of the cooled glass and tensile stress inside the glass, thereby improving the strength of the glass.

[0003] Curved glass is a special glass product with a curved surface. However, the existing curved glass tempering method has the problem of low curved surface arc size accuracy. Even for the curved glass produced in the same batch, not only is the overlap of the curved glass poor, but also the stresses in different parts of the curved glass are different, the uniformity is poor, and it is easy to break and self-crack. After careful observation, analysis and research on the existing curved glass tempering processing method, the applicant found that after the hot pressing of the glass blank, the curved glass blank in a softened state is supported by two rods distributed at intervals. Since the hot pressing of the glass blank is still in a softened state, the two sides of the hot glass blank are supported by two rods distributed at intervals. The curved glass blank will naturally deform under the action of its own gravity, which makes the curved surface size accuracy of the curved glass blank after cooling and forming non-uniform, which inevitably leads to different stresses in different parts of the curved glass, poor uniformity, easy to break and self-crack.
