Description
Technical field
The present invention relates to glass working arts field, specifically a kind of spherical glass processing technology.
Background technique
Arc glass is very widely used in the present age and brings the visual appearance of beauty, such as decorative wall, building, balcony, family
Tool etc..It usually needs in a mold to form the heated softening of the plate glass made according to service condition, then annealed system
At forming.With the industrialized fast development of society, people are continuously increased the use demand amount of glass, to glass quality requirement
Be continuously improved, therefore, how in the case where guaranteeing quality improving production efficiency, at the competition direction of glass processing industry.
Currently, glass bending processing flow is loading-heating-brake forming-cooling-unloading, that is to say will first be put down
Glass sheet, which is placed on, to be loaded in section and is transmitted by loading roller into being heated and softened in bringing-up section, and the glass after softening enters bending
Modification is carried out according to curved roller-way group in profiled section, makes glass further to ideal arc after then moving back and forth；Most
Achieve the purpose that sizing by air grid blowing cold quenching, then exports discharging.
Production bend glass uses the equipment such as curved steel rod and flexible axle, but this glass fibre reinforced plastic equipment more now, is producing
When curved strengthened glass, a kind of single surface glass can only be produced, spherical glass can not be produced, or in the mistake of production
Spheric curvature is unable to accurately control in journey, so that warpage occurs in the bend glass of production, is caused in the actual use process,
Muti-piece spherical glass can not be spliced, thus cause economic loss, and during glass size is biggish.
Summary of the invention
The purpose of the present invention is to provide a kind of spherical glass processing technologys, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the invention provides the following technical scheme:
A kind of spherical glass processing technology, including glass loads, glass heating, glass bending forms and glass unloading, feature
It is,
Glass heating is by being set to the upper and lower heater strip of heated table group upper and lower in heating furnace to glass simultaneously
It is heated, heating temperature is higher than heating temperature below the glass above the glass, carries out subregion above the glass and adds
Heat, the glass top heating temperature are gradually successively decreased by outer rim to centre；
The glass bending molding is that the glass after heating is removed heating furnace and is transported to molding roller-way, and adjustment is upper and lower
Air grid and the radian for forming roller-way, open upper and lower air grid and adjust separately the wind pressure of upper and lower air grid, make after sufficiently softening
Glass gradually forms under self gravitation effect with molding roller-way, while the tempering that cools down under the forced ventilation of upper and lower air grid.
As a further solution of the present invention: the glass after the abundant softening is moved back and forth on molding roller-way,
Reciprocal distance is greater than glass arc length 5-10cm.
As a further solution of the present invention: heating temperature is 705 DEG C -725 DEG C above the glass, below the glass
Heating temperature is 680 DEG C -690 DEG C.
As a further solution of the present invention: the heating time is 330s-680s.
As a further solution of the present invention: the upper and lower air grid blowing time started lags behind the molding roller-way
Crooked radian adjustment time, the lag time are 20s-25s.
As a further solution of the present invention: the upper air grid wind pressure is less than lower air grid wind pressure, and the upper air grid wind pressure is
200-1200pa, the lower air grid wind pressure are 900-3000pa.
As a further solution of the present invention: the blow-time of the upper and lower air grid is 200s-300s.
As a further solution of the present invention: the air outlet of the upper air grid to the glass top surface being located on forming roller road
Distance be 40-50mm, the distance of air outlet to the lower glass surface of lower air grid is 20mm.
As a further solution of the present invention: the upper and lower air grid and the crooked radian and the glass for forming roller-way
Finished product radian it is identical.
As a further solution of the present invention: the roller-way wheel diameter on the molding roller-way is grading structure.
Compared with prior art, the beneficial effects of the present invention are:
1, this method moves back and forth to glass by heating ceramic roller-way during heating to glass, and then makes
It is more uniform to obtain glass heating, reducing ceramic roller influences glass heating bring, and is making heating temperature above glass
Degree is higher than lower section heating temperature, furthermore partition heating is used in the top of glass, so that the heating temperature of glass upper surface is by outer
It helps and is gradually decreased to centre, so that the process of glass foreign aid and middle part in cooling during molding of the glass after heating
In receive different internal stress, and then the effect in internal stress have four it is circumferentially intermediate form stable bending, and then can be with
Process spherical glass；
2 present invention molding roller-way after the molding roller-way that the glass after abundant softening all arrives just starts bending deformation, Er Qie
After molding roller-way bending deformation starts, the blow-time of upper and lower air grid lags behind the bending time started of molding roller-way, Jin Erke
At the beginning of postponing glass tempering, so that glass can persistently keep soft state after coming out of the stove in a longer period of time, into
And the molding rate of glass improved, while being also possible that the cooling of glass rear and front end can start simultaneously at, before reducing glass
The temperature difference of rear end increases the precision of glass radian control in forming process, allows the glass particle degree after tempering more preferable；
3, the present invention is during carrying out glass cooling tempering, so that the wind pressure of upper air grid is less than the wind pressure of lower air grid, thus
During carrying out cooling tempering to glass, the temperature decrease rate of glass upper end is less than the rate of temperature fall of glass lower end surface,
It is described during glass cools down tempering, since the difference of local temperature causes the internal stress of glass upper and lower end face different, into
One step accelerates the rate that glass is bent upwards, and accelerates the curved rate of glass, can effectively avoid in unformed preceding glass
The problem of glass is down to tempering temperature, thus improve the quality of production.
