Abstract
The invention belongs to the field of tempered glass plate producing methods, and particularly relates to a simple method for producing a tempered glass plate. The method is characterized in that flat glass with the thickness of 3mm to 4mm undergoes cutting, edge grinding, cleaning, decal, drying and other pretreatment, is placed into a plate-shaped mould, and is sent into an electric heating tunnel furnace through a transfer roller; uniform heating to the temperature of 720 DEG C to 760 DEG C at the speed of 0.04 meter to 0.07 meter per second is carried out, and then releasing is carried out; the released plate-shaped mould is directly transferred to a workbench of an air stamping machine through the transfer roller, and is formed by using glass in a stamping mould of the air stamping machine; convection air at the natural normal temperature of 0 DEG C to 28 DEG C carries out fast cooling for 13 seconds to 15 seconds; and finally the tempered plate is removed from the mould. Compared with a technology in the prior art, the method provided by the invention has the advantages of simple steps, fast production speed, high efficiency and good quality.
Description
Technical field
The invention belongs to glass toughening equipment technology field, be specifically related to a kind of method of easy production toughened glass dish.
Technical background
Toughened glass dish due to have intensity high, can resistance to shock heating quenching, the characteristic of smooth surface, glittering and translucent, Environmental Safety, be well received by consumers.But the price of toughened glass dish is too high, hinder the universal of toughened glass dish.The reason of toughened glass dish high cost is to have added some special trace elements in toughened glass dish, and these micro-prices are very high.For the too high problem of workout cost, those skilled in the art of the present technique have invented a kind of glass toughening equipment technique, utilize simple glass rapidly cooling forming make simple glass change toughened glass into, use the toughened glass dish of this technique making without adding expensive trace element, cost reduces relatively, but in above-mentioned technique, heating, tempering, the demoulding all step by step operation break-down separately carry out, temperature requirement for cooling air in technique is high, poor continuity between heating and tempering operation, cooling time is long, cause the difficult quality control of toughened glass dish, the scrap rate of product is high.
Summary of the invention
The object of the invention is to solve that the physical toughened processing step of prior art glass disc is many, high to processing parameter requirement, the defect of difficult quality control, provide a kind of cost, yield rate is high, quality good, processing step is few, the method for, the easy production toughened glass dish that can realize automatization, large-scale production low to processing parameter requirement.
The present invention is achieved by the following technical solution:
It is a kind of method of easy production toughened glass dish, it is characterized in that the sheet glass of thickness 3mm～4mm through cutting, edging, clean, decal paper, after the pre-treatment such as oven dry, put into dish type mould, send in electrically heated continuous tunnel furnace by transfer roller, come out of the stove with the constant-speed heating to 720 of 0.04 meter～0.07 meter per second °～760 °, dish type mould after coming out of the stove is directly delivered to the worktable of air stamping machine through transfer roller, use the glass in the press tool of air stamping machine to make its moulding, use again the natural normal temperature convection current air rapid cooling 13 seconds-15 seconds of 0 °～28 °, from mould, take out tempering dish.
As a preferred version of the present invention: the length of electrically heated continuous tunnel furnace is 2.6 meters-2.7 meters.
Under the conveying of transfer roller, whole heating of the present invention, moulding, toughening process complete, and only need 40 seconds～60 seconds, can realize automatization, large-scale production.
Compared with the technique of the present invention and prior art, have that step is easy, production rate is fast, efficiency is high, the measured advantage of matter.Simple glass form physical toughened after, directly from mould, take out, without blowing mould tool being carried out to the demoulding with normal temperature air-flow again, the tempering dish that uses explained hereafter of the present invention is through overtesting:
1), from 1.2 meters fall in the air cement flooring of height, tempering dish can be damaged;
2) with 100 grams of iron balls from 1.1 meters of freedom of the air shock of a fall tempering dish medium positions, tempering dish can be damaged;
3) tempering dish can resistance to shock heating quenching, can bear the temperature difference of 100 ℃;
4) the self-destruction rate of tempering dish is low, and≤5%, the tempering dish self-destruction rate that prior art processes is made is greater than 10%.
