Technical Field

The invention relates to a glass corrugated plate hot bending device and application thereof, belonging to the field of glass deep processing.

Background

The hot bending glass is curved glass which is made by heating, bending and softening high-quality glass, forming in a mould and annealing in order to meet the high-quality requirements of modern buildings. The style is beautiful, and the lines are smooth. The glass breaks through the singleness of the plate glass, and is more flexible and diverse in use.

The hot bending glass can be classified into three categories, namely single bending, bending and composite bending, according to the shape. For single-bend architectural glass, the glass is relatively easy to heat bend. The common aquarium glass and counter glass exist in bent hot-bent glass, and the biggest technical difficulty of bent glass is that the straight line edge is bent, and the bent angle is easy to have the defects of mold marks and the like. Therefore, curved glass is also common, such as spherical glass, curved arch profile, glass washbasin, etc., and the glass requires a high technical level in hot bending operation, and the manufacturing of precise molds can be completed only by a professional hot bending furnace.

The glass corrugated plate is hot-bent glass with multiple bent surfaces, the distances of all the bent surfaces are short, the bending radius is small, and no professional hot-bending mold exists at present.
