A double-chamber four-station glass bending tempering device and control method

Abstract

A dual-chamber four-station glass bending tempering device and control method, comprising: a preheating furnace, a heating zone at one station, a heating zone at two stations, a heating furnace, a heating zone at three stations, a heating zone at four stations, a bending Steel forming section, arc changing mechanism, upper segment, segment extraction, matrix temperature control module, porcelain tube, heating furnace wire, furnace wire lead-out rod, thermocouple, conveying roller, glass, motor; according to different parts of the glass, the matrix is ​​fuzzy The control program automatically controls different heating temperatures and holding times. After the temperature of the whole piece of glass is consistent, it continues to heat up and keep warm. The temperature can be fixed to make the glass evenly heated step by step, to ensure the overall temperature of the glass is consistent, and to avoid the different heating temperatures of various parts from affecting the quality of the glass.

Description

technical field [0001] The invention relates to the technical field of tempered glass heating, in particular to a double-chamber four-station glass bending tempering device and a control method. Background technique [0002] The ordinary tempered glass process is to heat the glass to a tempering temperature range of 650-730 degrees, and then cool it rapidly. Because the cooling speed of the glass surface and the interior is different, a higher stress is formed on the glass surface. , since the softening temperature of glass is above 550 degrees, and the heating of the object is that the four sides and the outer layer are heated faster, and the center is heated more slowly, so that if the glass enters the heating section, the given heating temperature is about 700 degrees, it will The surrounding of the glass has been overheated and distorted, but the center has not been heated enough. However, the surface quality of glass used in automobiles is getting higher and higher. Th...

[0003] After searching, the publication number is CN1224406A, and the name is "Heating Furnace for Heat Treatment of Glass Plates", which includes a longitudinally elongated chamber, which accommodates a roller conveyor device for glass plates. The heating furnace is characterized in that , which comprises radiation heating means combined with first and second means for heating by forced convection of air in which the temperature of the air is controlled by regulating its circulation rate, said means being arranged respectively in said The top and bottom of the conveyor device, and therefore are respectively set above and below the glass plate being processed. During the heating process, the four sides and the outer layer of the glass plate are heated at a high temperature, while the center temperature is low, and the overall temperature of the glass plate is difficult to achieve uniformity. , the quality of the glass plate is not ideal
