Horizontal roller-free making process of toughened glass with double curved surface

Abstract

The present invention belongs to the field of glass forming and toughening technology. The making process of toughened glass with double curved surface includes: setting plate glass into the double-curve forming mold in L-shaped bogie, lifting with a lifting mechanism from the loading and unloading area A to pushing area B and pushing into hot bending area C, hot bending to form in C, pushing the L-shaped bogie to pass through upper turnover area D to wind cooling area E, wind cooling to toughen in area E between the upper and lower wind grates, backing to area D and descending to lower turnover area F, and backing to area A for unloading via the passage G under area C. Then, the next circulation begins. The said process is reasonable, power saving, high in finished product rate and suitable for continuous production, and the toughened glass has good optical performance.

Description

technical field [0001] The invention relates to the technical field of glass forming and tempering, in particular to a method for manufacturing a horizontal non-roller table hyperboloid tempered glass. Background technique [0002] There are roughly two types of existing methods for making hyperboloid tempered glass: one is the hanging tempering method. The glass runs along the track through a special spreader in a production line equipped with a channel-type heating chamber and a press-formed air grille. Its main disadvantage is that the heating chamber cannot be well sealed, resulting in a serious waste of energy, and there are hanging marks on both sides of the upper edge of the glass, so it is not suitable for high-quality production, large format or heavy. Glass. The second is the horizontal roller type hyperboloid glass tempering method commonly used at home and abroad. The main production method is to send the flat glass to the ceramic roller table in the heating zon...

AI Technical Summary

Problems solved by technology

The main disadvantages are strict requirements on the precision of molds and related mechanisms, high equipment manufacturing costs, and the ceramic roller table is expensive and easily damaged, and the maintenance cost of the roller table and the heat preservation of the heating section are high. Reciprocating operation on the road, the glass surface is easily damaged, and affects the optical performance of the tempered glass, and the yield is not high
