Heat insulating device for improving formation of hot bent glass

Abstract

The invention relates to a heat insulating device for improving the formation of hot bent glass. The device is arranged on one side of a glass mold and used for insulating heat for a glass workpiece to be processed on the glass mold; the device comprises an umbrella cover heat insulating plate, a base and a supporting mechanism arranged on the base; the umbrella cover heat insulating plate is arranged on the base by use of the supporting mechanism in such a manner of being lifted vertically; a positioning column and a fixing fastener arranged on the positioning column in such a manner of sliding up and down are further arranged on the base; and under a working position, the base is fixedly connected with the glass mold by use of the fixing fastener. Compared with the prior art, the heat insulating device is simple and compact in overall structure, small in volume, economic and practical, low in heat absorption, good in heat barrier effect, capable of effectively reducing the energy consumption, convenient to mount and low in fabrication cost.

Description

technical field [0001] The invention belongs to the technical field of glass forming technology, and relates to a heat insulation device, in particular to a heat insulation device for improving hot bending glass forming. Background technique [0002] The existing hot bending process for large-area glass such as buses and automobiles mainly controls the spherical surface of the glass through heating and adjustment. However, when the softened glass is molded by its own weight, due to the large area of ​​the glass, the conditions for adjustment by heating are limited, and the spherical surface at the edge of the glass will be too large locally, which cannot meet the technical requirements. [0003] In view of the above problems, the existing solution is: at the position where the spherical surface tends to be too large, a certain number of thicker iron plates, channel steel and other steel materials are arranged to absorb heat at this position. However, this method is greatly ...

AI Technical Summary

Problems solved by technology

However, this method is greatly affected by voltage fluctuation and hot bending operation technology. For example, when the heating speed is fast, the heat absorption effect of iron plate, channel steel and other steel materials is obvious, but when the heating speed is slow, the iron plate, channel steel, etc. The heat-absorbing effect of steel materials such as steel is reduced, resulting in heat-absorbing instability, which makes the dimensional stability of the glass spherical surface poor. Directly affect the cooling effect of the glass and cause waste of energy consumption
