Technical field
The present invention relates to glass bending tempering technology field, the production dress of specifically a kind of Two-dimensional Surfaces safety glass
Put and method.
Background technology
The production method of present level roller bed type Two-dimensional Surfaces safety glass, during glass transfers, molding tempering section
Interior molding roller-way group meets the glass after heating to rapidly enter with horizontality, until glass is completely in molding tempering section
Molding roller-way group.In BENDING PROCESS, the molding roller-way group in molding tempering section bends to set molding shape from flat shape
Shape.
Analyzed by above production method, it is known that：
1. transferring process needs the regular hour, and its temperature can decline.With the increase of glass arc length transfers the time can be increasingly
Long, the amplitude that glass temperature declines can be increasing.When glass arc length exceedes certain limit, temperature drop is excessive, especially
The front end of glass, glass are hardened, and fried mouth occurs or even burst after bending.
2. the brake forming process of glass, it is also desirable to regular hour, equally along with temperature drop.The brake forming time
As the increase of glass arc length can be increasingly longer, the amplitude that glass temperature declines also increases therewith.When glass arc length exceedes necessarily
Limit, when temperature drop is excessive, the especially front end of glass, the thermograde that cannot be set up required for glass tempering, just
Tempering cannot be completed.
3., in order to overcome temperatures above to decline the drawbacks of bringing, need to improve the temperature that bending steel process is required.This
Sample allows for the heating energy consumption increase of glass heating process and increases heat time heating time, and the glass after heating is excessively soft and product optics matter
Quantitative change is poor.
The problem of the production method presence of horizontal roller formula Two-dimensional Surfaces safety glass is at present：Need to improve bending tempering
The temperature of technological requirement, energy consumption is big, low production efficiency, product optical quality are poor；During the production larger bending safety glass of arc length,
If arc length is more than the Two-dimensional Surfaces safety glass of 4500mm, there is the defects such as fried mouth, molding be inaccurate, cannot even produce.
The content of the invention
The energy consumption that exists for the production method of above-mentioned existing horizontal roller formula Two-dimensional Surfaces safety glass is big, production effect
The problems such as rate is low, product optical quality is poor, the present invention provide a kind of process units and method of Two-dimensional Surfaces safety glass.

Cut；The forniciform degree of crook of the preforming is not more than the degree of crook of the set forming shape of glass to be bent；The pottery
The flexible set forming shape for glass to be bent of porcelain roller road group.
The bending section of the molding roller-way group be in circular arc, its crooked radian radius be r, the set molding of glass to be bent
The radius of shape is R, wherein r >=R.
If the horizontal segment of molding roller-way group is k, 0 k with the length ratio of bending section。
If the horizontal segment of molding roller-way group is k, k=1 with the length ratio of bending section.
The bending section of the molding roller-way group parabolically shape.
The bending section relative level of the molding roller-way group is bent upwards.
The bending section relative level of the molding roller-way group is bent downwardly.
A kind of method for producing safety glass using process units as above, including procedure below：
1）Heating process：Glass is heated to the temperature of bending steel process requirement in bringing-up section；
2）Transfer process：Glass bringing-up section ceramic roller group and molding tempering section molding roller-way group joint transmission under into into
Type roller-way group, the part that the molding roller-way group in molding tempering section is docked with bringing-up section ceramic roller group are in flat shape, remaining
In preforming bending, the horizontal segment of molding roller-way group is tangent at demarcation line with bending section for part；
3）BENDING PROCESS：Molding roller-way group in molding tempering section bends to set forming shape, and the glass for heating after-tack exists
It is close to roller-way molding therewith in the presence of gravity, remainder bends to set forming shape from pre-form shape；The preformation
The forniciform degree of crook of type is not more than the degree of crook of the set forming shape of glass to be bent；
4）Cold quenching process：Blowing cold quenching, until completing tempering.
Beneficial effects of the present invention：
Molding roller-way group is set to horizontal segment and bending section by the process units of the Two-dimensional Surfaces safety glass that the present invention is provided,
During glass transfers, near heating section mass in flat shape, remainder is in the molding roller-way group in molding tempering section
Pre-form shape.That is, the obvious glass front of temperature drop is preformed when the process of transferring is completed.Reduce
There is fried mouth or even the possibility for bursting, especially faceplate in glass；The less temperature drop of glass front, is production arc length
Larger bending safety glass provides condition, can such as produce bending safety glass of the arc length more than 4500mm；
Due to glass, during transferring, glass front is preformed, glass need not heat it is very soft just come out of the stove, so can
Reduce bending the temperature that steel process is required with appropriate, energy consumption when glass is heated in the heating furnace is reduced, the time shortens, and is reduced
Energy consumption, improve production efficiency；It is due to can suitably reduce bending the temperature of steel process requirement, harder when glass is come out of the stove, can make
The optical quality for obtaining glass is significantly improved；
The present invention solves the problems, such as the production method of present level roller bed type Two-dimensional Surfaces safety glass well.Production
Energy consumption drop bottom, production efficiency are improved；Product optical quality is significantly improved；The larger bending safety glass of arc length can be produced, such as
Two-dimensional Surfaces safety glass of the arc length more than 4500mm.
