Processing technology of glass piece

Abstract

The invention relates to a processing technology of a glass piece. The processing technology comprises the following steps of proportioning, specifically, weighing various raw materials according to a designed formula list, and uniformly mixing in a mixer; melting, specifically, heating the prepared raw materials at a high temperature to form uniform bubble-free glass liquid, which is a very complex physical and chemical reaction process, melting and forming the glass in a melting furnace, converting the molten glass liquid into a solid product with a fixed shape, and forming within a certain temperature range, and which is a cooling process, firstly converting the glass into a plastic state from a viscous liquid state and then converting the plastic state into a brittle solid state; annealing, specifically, the glass is subjected to intense temperature change and shape change in the forming process, the change leaves thermal stress in the glass, and the thermal stress can reduce the strength and the thermal stability of a glass product; and four-edge polishing, specifically, putting the annealed glass piece on a horizontal glass piece processing and producing device, and polishing the four edges of the glass piece.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a glass processing technology. Background technique [0002] With the increasing development of the glass decoration industry, there are many types of glass decorations, different shapes of processing, and various types of glass processing equipment. Among them, glass edging is an essential process for cut glass. [0003] In actual processing and production, it is often necessary to perform edge grinding on two or four sides of a rectangular glass at the same time, while the existing technology can only edge one side of the glass at a time, for two or four sides Edge grinding needs to be processed in two or four times. At the same time, due to the different sizes of glass, when processing glass of different sizes, it is necessary to re-adjust the processing device, which is time-consuming and laborious, and it is easy to correct during the grinding process.
