Abstract
The invention belongs to glass working arts field, and in particular to a kind of safety glass stress pattern improves equipment；The present invention is changed to 4*6 in original live-roller bottom design and installation deep bead, while by the size of original aramid fiber rope by 4*12, by installing deep bead additional and reducing contact surface, so as to reduce the stress pattern of safety glass.
Description
Technical field
The invention belongs to glass working arts field, and in particular to a kind of safety glass stress pattern improves equipment.
Background technology
High-quality float glass is isotropic material, and the glass after glass tempering is due to bearing stress and interior being present
Portion's tensile stress, safety glass is set to be changed into anisotropic material, when light passes through safety glass, due to existing inside safety glass
Stress, light is set to be decomposed into the different polarised light of two beam spread speeds, when observing safety glass, due to the original of light interference phenomenon
Cause, when various light amplitude directions are identical, light intensity is strengthened and produces bright field, both speck.When amplitude direction is opposite, light intensity
It is smaller and produce dark field, both blackenings.
When people are under certain lighting condition, observe safety glass with angle at a certain distance, in safety glass table
Face can be appreciated that some distributions not coloured speckle of very regular band, and this colored speckle is " stress pattern ", and it is
The optical characteristics that all safety glass all have, the performance of safety glass is not influenceed.But safety glass is as safety glass
Using more and more extensive, appearance requirement more and more higher of the people to glass.The presence of safety glass stress pattern can be to glass
Outward appearance bring detrimental effect, or even have influence on the overall appearance effect of building.
It is mainly relevant with heating factors, cooling factor, thickness of glass, glass kind that safety glass produces stress pattern.It is existing
Tempering apparatus processing mode be horizontal roller formula tempering form, after glass is heated to tempering temperature, into cooling section carry out
Tempering processing, the live-roller gear of tempering section is using steel shaft winding aramid fiber rope, and aramid fiber rope specification is 4*12, the winding spacing of aramid fiber rope
For 45mm, because glass is driven on aramid fiber rope, the roller-way capacity of heat transmission is excessive, and the part contacted with roller-way is rapidly cooled, first
Cooled place can form larger compression, and the heat for the safety glass walked by aramid fiber rope band is greater than cooling wind and taken away
Heat, safety glass surface temperature has differences, so as to cause safety glass stress difference to be present.
Safety glass is more and more extensive as safety glass applications, and people require more and more higher to the appearance of glass.
The presence of safety glass stress pattern can bring detrimental effect to the outward appearance of glass, or even have influence on the overall appearance effect of building
Fruit.
The content of the invention
In order to solve the above problems, it can reduce the improvement of stress pattern glass tempering it is an object of the invention to provide one kind and set
It is standby.
The present invention is achieved through the following technical solutions：
A kind of safety glass stress pattern improves equipment, including upper air grid, lower air grid and located at upper air grid and lower air grid it
Between live-roller, the live-roller bottom is additionally provided with deep bead.
It is preferred that the live-roller outer surface is wound with aramid fiber rope.
It is preferred that the size of the aramid fiber rope is 4*6mm.
It is preferred that the winding spacing of the aramid fiber rope aramid fiber rope is 45mm.
The present invention is in original live-roller bottom design and installation deep bead, when glass tempering, the air-flow of air grid nozzle ejection
Because that can not be flowed away under live-roller, an air cushion can be formed under whole safety glass plate face, air-flow is merely able to the side of slave unit
Portion flows out, and reduces the contact area of safety glass and roller-way, reduces the heat taken away by roller-way conduction.By original aramid fiber rope
Size is changed to 4*6 by 4*12, reduces the contact area of safety glass and roller-way, reduces the heat taken away by roller-way conduction.
Original tempering section is made up of air grid and transmission, causes the factor of tempering stress spot mainly to be walked by aramid fiber rope band
Safety glass amount of localized heat, have differences safety glass surface temperature, so as to cause safety glass stress difference to be present.
The present invention is mainly reduced because of glass and roller-way contact and with not in contact with temperature difference caused by roller-way part, being kept out the wind by installing additional
Plate, make to form a space between the lower surface of glass, live-roller, lower air grid, make that a gas can be formed under safety glass plate face
Pad, while the aramid fiber rope on live-roller is heated, so as to reduce the stress pattern of safety glass.
Brief description of the drawings
Fig. 1 the structural representation of present invention.
Specific embodiment
With reference to embodiment, the present invention is described in further detail, is managed to help those skilled in the art
The solution present invention.
See Fig. 1, a kind of safety glass stress pattern improves equipment, including upper air grid 1, lower air grid 2 and located at the upper and of air grid 1
Live-roller 3 between lower air grid 2, the bottom of live-roller 3 are additionally provided with deep bead 4.The outer surface of live-roller 3 is wound with aramid fiber rope, aramid fiber
The size of rope is 4*6mm, and winding spacing is 45mm.Carrying out tempering processing is, the lower surface of glass to be toughened 5, live-roller 3, under
A space is formed between air grid 2, makes that an air cushion can be formed under safety glass plate face, while heated the aramid fiber on live-roller
Rope, so as to reduce the stress pattern of safety glass.
Above-described embodiment, simply presently preferred embodiments of the present invention, is not used for limiting the scope of the present invention, therefore all with this
The equivalent change or modification that feature and principle described in invention claim are done, all should be included in scope of the invention as claimed
Within.
