Processing method for better controlling spherical degree of irregular spherical glass

Abstract

The invention relates to the technical field of glass ball processing, in particular to a processing method for better controlling the spherical degree of irregular spherical glass, which solves the problem that large spherical special-shaped glass is not easy to form and reduces the control requirement on the internal temperature of a heating furnace. The method comprises (1) a step of manufacturing a mold, namely a step of cutting a hot-rolled steel plate with the thickness of 5 mm into battens, assembling and welding the battens, reinforcing a base with 5 cm * 10 cm channel steel, and welding the edges together through 8-10 mm cold-drawn steel rods or stainless steel rods; (2) a step of flatly laying high-temperature fiber cloth on the mold; (3) a step of laying flat glass on the high-temperature fiber cloth; (4) a step of heating and forming, namely a step of heating the mold in the step (1) and the plate glass in the step (3) to the softening temperature of the plate glass in the step (3) by using a heating furnace, and enabling the plate glass to be attached to the surface of a mold cavity of the mold to be shaped into a bent shape; and (5) a step of cooling and taking out a workpiece.

Description

technical field

[0001] The invention relates to the technical field of glass sphere processing, in particular to a processing method for better controlling the spherical degree of irregular spherical glass. Background technique

[0002] As we all know, the forming of curved glass is formed by hot bending of molds. Flat glass is placed on a prefabricated mold and heated in a bending furnace. After the glass reaches the softening temperature, it sags by its own weight to form a curved surface.

[0003] The curvature of the spherical surface of the glass is different at each point during the hot-bending firing process of the special-shaped glass based on the large spherical surface. During the firing process of the normal hollow mold, the curvature requirements of the glass cannot be met, and the curvature of the center is large, and the curvature of the edge is small. phenomenon (commonly known as "glass belly"). The temperature control of each part of the heating furnace is ...
