A Heat Insulation Device for Improving the Forming of Hot Bending Glass

Abstract

The invention relates to a heat insulation device for improving the forming of hot-bending glass. The device is arranged on one side of the glass mold and insulates the glass workpiece to be processed on the glass mold. The device includes an umbrella surface heat insulation board , a base and a support mechanism arranged on the base, the umbrella surface heat insulation board can be vertically lifted on the base through the support mechanism, and the base is also provided with a positioning column and can be slid up and down on the positioning column In the working state, the base is fixedly connected with the glass mold through the fixing buckle. Compared with the prior art, the present invention has simple and compact overall structure, small volume, economical and practical, less heat absorption, good heat shielding effect, can effectively reduce energy consumption, is convenient to install, and has low production 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
