Abstract
An air cushion method for curving and strengthening glass includes such steps as putting the heated glass over the hot airflow in shaping chamber to suspend it there, raising up it by the internal circulating hot airflow to make it adsorbed on the lower surface of upper mould, moving the shaping mould to the position under the glass, releasing the glass onto said shaping mould, shaping, moving it out of shaping chamber and cooling for strengthening. Its advantages are simple structure, high shaping precision and low energy consumption.
Description
Technical field
The present invention relates to a kind of method of producing curved tempered glass, particularly a kind of air cushion method for stregnthening and shaping glass elbow by internal circulation of hot airflow.
Background technology
Horizontal glass tempering method is the Technology that at present state-of-the-art in the world curved tempered glass is produced, and the core of this Technology to be glass after how will heating in forming room raise up, and then it is released on the forming mould exactly.
The method of U.S. glasstech company this kind technology is: with process furnace same level position ceramic roller is arranged in forming room, be used for carrying with the support heating after glass, below ceramic roller gap, many air nozzles are housed, after glass enters forming room, form air cushion between the nozzle jet-stream wind, it and glass, glass is held up from roller-way, this moment, patrix descended, make it form air cushion, glass is held up from roller-way, this moment, patrix descended, make its lower surface and glass gluing, because the top blower fan from the blowing of venting hole side direction, makes and produces negative pressure in the patrix, glass is also promoted together by the patrix adhesive, in the time of below the mould trolley that is loaded with curved mould arrives glass, last downstream is cut off, and glass is fallen moulding on the curved mould by deadweight, sends into the cooling of air grid tempering again.In order to make the glass in the forming room can keep suitable temperature when the bending, it is equipped with heating unit in the forming room bottom, the hot method glass of this gas be raised with moulding process in, not only a large amount of hot gas flows is discharged from outdoor in the forming room, it will keep having in the patrix bigger being enough to adsorb the negative pressure of glass simultaneously, just must be at the sizable blower fan of gas port one side allocating power, its result is exactly a high energy consumption, use this method processing curved tempered glass, more than 30 kilowatt-hour of the energy consumption of average unit output up to every square metre.
Summary of the invention
The purpose of this invention is to provide a kind of air cushion method for stregnthening and shaping glass elbow by internal circulation of hot airflow, the notable feature one of this method is that hot gas flow is under the effect of high-temperature axial flow fan, only at forming room's internal recycle, and not to outdoor discharging; The 2nd, expensive ceramic roller no longer is installed in the forming room, after glass entered forming room, the direct hot gas flow institute support that is blown out by the air cushion case was so it is good to use the curved tempered glass of this method processing to have the surface optical performance, brake forming commentaries on classics degree height, the characteristics that energy consumption is little.This method has also been simplified equipment, has reduced cost.
The objective of the invention is to be achieved through the following technical solutions: further comprising the steps of:
(1), the glass after will heating sends into the hot gas flow top in the forming room, in this suspension.
(2), utilize internal circulation hot gas stream from bottom to up that glass is steadily held up the lower surface that is adsorbed on patrix.
(3), forming mould is moved to the below of glass, and glass is released in moulding on this forming mould.
(4), glass and forming mould are shifted out forming room and carry out the tempering cooling.
The blast of the internal recycle air-flow in described step (1) and (2) is 4000-7000P
a
Temperature in described forming room is controlled at 500-750 ℃.
The device that is used for producing internal circulation hot gas stream in described step (1) and (2) comprises: air cushion case, blower fan, circulation tube, be covered with production well above the air cushion case, connect the outlet of blower fan in its lower section, the two ends of circulation tube are connected with the air outlet of described patrix and the inlet mouth of blower fan respectively, are covered with air inlet port below patrix.
The used device of this method also comprises the heating container that is positioned at below the described air cushion case, and heating unit is arranged within it, and this heating container is series between the inlet mouth of described circulation tube and blower fan.
What be used for delivering forming mould in described step (3) is particular manufacturing craft dolly and the track supporting with it, and this track cross level is through forming room and the cooling air grid that is adjacent, and mould trolley can back and forth move on this track.
Also comprise the heating steps between described step (3) and (4), temperature is 600-650 ℃, and the time is 5-120 second.
The present invention has following unusual effect: the one, do not use ceramic roller in the forming room, and this not only makes equipment manufacturing cost greatly reduce, and has reduced the friction of glass surface and solid matter simultaneously, has improved the surface optical quality of toughened glass; The 2nd, hot gas flow is only at forming room's internal recycle, and not initiatively to outdoor discharging, it has only used a high-temperature axial flow fan that power is little, just simultaneously can make bottom air cushion box-shaped become the air cushion of support glass, then form the negative pressure of adsorbable glass in the patrix, as long as be no more than permissible value, how the size of glass and shape change can not exert an influence with lifting glass to patrix absorption.

Fig. 2 is the apparatus structure synoptic diagram of use of the present invention.
The invention will be further described below in conjunction with accompanying drawing.
Embodiment
See also Fig. 1 and Fig. 2, when glass 1 after process furnace 2 internal heating are good, be transported to forming room 4 by roller-way 3, the hot gas flow support that glass 1 is blown out by air cushion case 5, the airflow acting force that inertia that roller rest road 3 is carried and air cushion case 5 tilt continues to move ahead, pin 6 stops spacing until being positioned, patrix 7 declines this moment, be adsorbed on its lower surface until contact glass 1 and with it, then patrix 7 is being with glass 1 to promote together, bending mould drives lower edge track 9 in the mould trolley (not shown), and to enter moulding 4 indoor, be positioned below glass 1, this moment, aerofoil fan 8 was out of service, and hot gas flow stops, lose negative pressure in the patrix 7, glass 1 is dropped by deadweight and be bent moulding on bending die.Temperature in the forming room 5 is controlled at 500-750 ℃, determines according to the glass of different size.If depend merely on the flexural deformation of dead load forming glass 1 when not yet in place, can also in forming room 4, continue heating for some time, can determine the length of this time according to the curvature of thickness, softening degree and the moulding of glass, generally at 5-120 between second, so that glass 1 and mould are fitted fully.After this mould trolley carries glass 1 after the bending and enters the cooling air grid (not shown) adjacent with forming room 4, makes its tempering cooling.
Lower surface at patrix 7 is covered with suction hole 71, and venting hole 72 is arranged in the above.Upper surface at air cushion case 5 is covered with gas orifice 51, has air inlet port to be connected with the air outlet of aerofoil fan 8 in its lower section.
To keep certain temperature in the forming room 4 in order making, a heating container 10 to be set below air cushion case 5, its outlet is connected with the inlet mouth of aerofoil fan 8, and heating unit 11 is arranged within it.Between the venting port 72 of the inlet mouth 12 of heating container 10 and patrix 7, be connected circulation tube 13, so that the high temperature gas flow in the forming room 4 greatly reduces energy consumption in internal recycling.The flow of the air-flow that produces on air cushion case 5 surfaces is 10000-20000m
3/ h, blast are 4000-7000P
