Description
Technical field
The utility model is related to glass toughening technology field, more particularly, to a kind of glass tempered air grid.
Background technology
In recent years, Domestic Automotive Industry fast development, safety glass has also obtained automobile industry because of its security performance
Accreditation.Glass tempering is that a kind of technology strengthened to glass, i.e. glass are heated to close to after softening temperature in heating furnace,
Come out of the stove rapidly compressing, subsequently into cooling device cooling, to reach the purpose of reinforcing glass intensity.Because consumer is to vapour
The appearance requirement more and more higher of car, the outer forming technique of stove is also produced under this situation, is molded by outside stove, and glass can be entered
Row specially treated, reaches preferable shape, curvature and tempering intensity, and under normal circumstances, the mechanical strength of safety glass is general
4-6 times of logical glass.With the development of society, frivolous glass has become a kind of trend.
But in the prior art, when the glass plate of high temperature takes out from annealing furnace and is cooled down into air grid, its one end
Arrival end is introduced into, cooling zone is then passed through with certain speed, until being left from the port of export.Into the glass of cooling zone arrival end
That end of glass plate can first carry out ventilating and cooling, and other parts are still in the condition of high temperature, can so cause the first of glass plate to enter to hold
Can not be cooled down simultaneously with inside of glass plate, it will produce internal temperature stress, just enter end part also very likely occur it is larger
Deformation, influences glass appearance；And harm of the such case to frivolous glass and deep camber glass is more serious, surface can be caused to hold
Split, not only influence outward appearance, can also produce quality problems.And if after full wafer glass plate is put into air grid, it is then turned on cooling, and
After end, air grid is closed, and full wafer takes out glass plate, and restart again after next glass sheets are put into cooling zone completely, so
The blower fan of air grid is just frequently opened/closed, it will substantially reduce fan life, while needing that glass plate full wafer is put into and full wafer takes
Go out, will also be taken considerable time in this convergence process, substantially reduce cooling effectiveness.
Existing glass cooling device cannot but meet the production requirement of frivolous safety glass, especially when frivolous glass from
In annealing furnace out, just by cooling device when, due to being that one end is introduced into cooling so that inhomogeneous cooling is even, in frivolous glass
Local temperature difference is formed on glass, and causes deformation inconsistent, easily cause the moderate finite deformation of glass edge, or even due to internal temperature
Stress causes cracking, unfavorable to actual production.Therefore the cooling device for needing exploitation new, to meet actual production demand.

When glass plate 4 has just enter into cooling zone 3, the blast of its wind-engaging needs to be adjusted, will with the type face for meeting glass plate 4
Ask.But generally, a Fans can be only installed, the downward blast of blower fan is all fixed impartial on upper air grid 1, therefore
In order to control the blast in adjustment adjustable fan blade area 12, the utility model to connect a upper air knife in the upper end in the adjustable fan blade area 12
Control valve 17, to control the blast size into adjustable fan blade area 12.The upper air knife control valve 17 can be by artificial behaviour
Carry out folding, when standard-sized sheet if, and Semi-folding, Quan Heshi identical with the blast that fixed fan blade area 13 receives, then into adjustable
The blast in fan blade area 12 just corresponding reduction, specific opening degree can optionally be carried out according to the cooling situation of glass plate.
Wherein, the upper end of the upper air knife control valve 17 can connect air knife position control disk 16 by an actuator 18,
The upper end of the air knife position control disk 16 is fixed on air grid base 15, and the upper air grid base 15 is provided with windward
Machine.
It is that two sides cools down simultaneously during cooling glass plate.Due to the adjustable fan blade area 12 and fixed fan blade area 13 of upper air grid 1
Blast, and in order to synchronously realize this differentiation on lower air grid 2, the utility model is positioned at the side of the arrival end 31
The lower end of lower fan blade 21 be provided with lower air knife control valve 22, be aligned with the upper air knife control valve 17, the lower fan blade for being controlled
21 is suitable with the scope in adjustable fan blade area 12, and the lower air knife control valve 22 can be fixed on lower air grid base 23, institute
State lower air grid base 23 and lower blower fan is installed.
It should be noted that upper and lower air grid base described in the utility model can be as flange port with fixed entirely upper leeward
Grid, and as air inlet, obtained from blower fan and be blown into wind.
In actual production, the upper air knife control valve 17 can be first manually adjusted with the lower air knife control valve 22
Opening degree, is tentatively controlled with type face and the rebound amount of glass plate 4, and after glass plate 4 enters fixed fan blade area 13, is maintained
The blast up and down of the position of adjustable fan blade area 12 is constant, and the blast of the upper and lower air grid in delivery roll rear can be according to the curvature of glass plate, anti-
Elasticity is adjusted, it is therefore an objective to reduce glass plate caused bounce-back of cooling after compressing, improve the stability of product.
Preferably, upper and lower blower fan can be different blower fans, or same blower fan, or connect the blowing mouth of same blower fan simultaneously, only need
Regulation upper air knife control valve 17 and the opening degree of the lower air knife control valve 22, realize the change of blast, to adapt to respectively
The type face of glass plate 4 requires.
Wherein, it is the curvature of matched glass plate 4, in a specific embodiment, the song of convex described in the utility model
Rate radius is 9950mm, includes fan blade 11 in two panels on each in fan blade group, and centre-to-centre spacing is 54.5mm between group, upper fan blade in group
11 centre-to-centre spacing are 28mm, and the every upper center of fan blade 11 is provided with the air holes of diameter 8mm；In a specific embodiment, it is described adjustable
Fan blade area includes 3 upper fan blade groups, i.e., 6 upper fan blades.
Similarly, the radius of curvature of the concave panel is 9950mm, and fan blade 21 under two panels is included in each lower fan blade group, and
Centre-to-centre spacing is 54.5mm between group, and the lower centre-to-centre spacing of fan blade 21 is 28mm in group, and the every center of lower fan blade 21 is provided with the wind of diameter 8mm
Hole.
It should be noted that the air holes quantity of fan blade is than air grid general at present in upper and lower air grid described in the utility model
Air holes is less, general to lack 20% or so, when the blast of blower fan blowing is fixed, because air holes quantity is few, and its corresponding unit wind
The blast of hole air-out is just big, may be such that the cooling effectiveness in glass plate unit curvature (or unit area) is higher, a whole set of air grid
Refrigeration is more preferable.Such as in cooling procedure, blower fan aperture 80% of the present utility model can reach the blower fan of existing equipment 100%
The aperture refrigeration to be reached, greatly improves cooling effect, and (convex matches glass with concave panel due to arcuate structure
Glass plate), can more uniformly act on glass pane surface during cooling, improve the performance of glass after tempering, with produce it is more frivolous,
Curvature glass higher, and original air grid cannot just produce such glass.
