Problems solved by technology
If the process parameters are not set properly, it will cause cracks in the glass, uneven surface and other problems, which will affect the product quality.
In the prior art, the process parameters of glass tempering are mostly set by technicians based on experience, which greatly increases the production cost, and has high requirements for technicians, which cannot meet the needs of modern production scale

Embodiment Construction
[0040] The present invention will be described in detail below in conjunction with specific embodiments.
[0041] A method for setting process parameters of a glass tempering process, comprising:
[0042] (1) Divide tempered glass into several categories according to the type of tempered glass, glass thickness, number of glass pieces in one batch and total area of glass, set the optimal process parameters for each category, and calculate the optimal process parameters for each category The optimal process parameters are scored, and the process database is constructed according to the optimal process parameters and scores of each category.
[0043] In this embodiment, the quality of the tempered glass obtained when a corresponding type of glass is tempered by using the process parameters is used as the basis for scoring the best process parameters corresponding to this type.
[0044] In this embodiment, it can be divided into three categories according to the types of glass,...

The invention discloses a technological parameter setting method of a glass toughening technology. The method converts the artificial experience into technology database. The data is automatically matched according to the kinds of the toughened glass, and corresponding optimal technological parameters can be obtained from the technology database. The obtained optimal technological parameters can be used to guide the corresponding toughening process. The provided method reduces the dependence on artificial experience. Moreover, during the toughening process, the temperature and wind pressure of the toughening furnace is monitored in real time, and the obtained node data is outputted and stored. Because data of temperature and pressure of a toughening furnace in each node during the toughening process is output and stored, when the produced toughened glass is not qualified, people can find the reasons according to the outputted node temperature and wind pressure.
Description
technical field [0001] The invention relates to the technical field of glass tempering, in particular to a method for setting process parameters of the glass tempering process. Background technique [0002] With the development of economic globalization, our country puts forward the requirements for the production demand and quality standards of industrial and civil glass products to be in line with the world's advanced level. As a safety glass, tempered glass is obtained from the original glass after tempering. Its impact strength is four times or more higher than that of ordinary glass. When it is broken by external factors, it will not form a sharp "knife surface", but It becomes almost uniform small granular glass slag, which has the advantage of not being easy to hurt people. Therefore, in the use of safety glass in the global automotive industry, construction industry, instrument and furniture industries, tempered glass accounts for more than 60%. Continuously expandi...
