Description
Technical field
The utility model belongs to liquid crystal substrate glass and manufactures field, is specifically related to the shaping warpage setting device of a kind of liquid crystal substrate glass.
Background technology
Produce in the manufacturing processed of liquid crystal substrate glass adopting overflow downdraw, glass is in the process flowing through forming furnace, if there is larger temperature head change or be subject to mechanical external force, sheet glass regional area larger area will be made to bend, namely cause sheet glass warpage bad.Sheet glass is in a two-dimentional temperature field in body of heater, the temperature variation of the existing flow direction, have again non-streaming to temperature variation, warpage adjustment must take into account the factor of these two aspects, should ensure that non-streaming is to direction temperature equalisation, regulate temperature lowering curve to reasonable temperature range state again.
Forming furnace technical cooling water pipe, mainly plays the quick cooling and shaping of sheet glass and the object increasing molding zone temperatures adjustment nargin.In the prior art, forming furnace technique water pipe patchhole is circular hole, only has the technique water pipe using different pore size, and the different patchhole height location in adjustment upper, middle and lower, to change the effect to glass cools sizing, and the heater power of formula distribution is arranged by adjustment shaping area levels, or automatically control by DCS the electric thermo-couple temperature instruction adjusting the installation of corresponding heater locations, the power that indirect change well heater applies, finally reach and control sheet glass in stove and flow to the temperature difference and non-streaming to the object of temperature equalisation, ensure the warpage grade of sheet glass.
Utility model content
The purpose of this utility model is to provide a kind of liquid crystal substrate glass shaping warpage setting device, to overcome the defect that above-mentioned prior art exists, the utility model is convenient to accurately control the falling temperature gradient of sheet glass on forming furnace current direction, effectively improves and improve shaping warpage quality taste.
For achieving the above object, the utility model adopts following technical scheme:
The shaping warpage setting device of a kind of liquid crystal substrate glass, the liquid glass liquid comprising overflow device and overflow device can be made to flow out is shaped to the molding device of sheet glass, molding device is provided with two upper holes, two meta holes and two the next holes, two described upper holes, two meta holes and two the next Kong Jun are symmetrical about sheet glass, and upper hole, meta hole and the next hole are waist shaped hole, in waist shaped hole, selectivity arranges the water-cooled tube that can move left and right wherein.
Further, the top of each waist shaped hole is equipped with graduated scale, and the end of water-cooled tube is equipped with the water-cooled tube mark line vertical with graduated scale.
Further, water-cooled tube mark line overlaps with the diameter of water-cooled tube end vertical direction.
Further, when arranging water-cooled tube in waist shaped hole, shutoff tampon is set in the gap between waist shaped hole and water-cooled tube.
Compared with prior art, the utility model has following useful technique effect:
The hole being used for inserting water-cooled tube is designed to waist shaped hole by the utility model, not only can use the water-cooled tube of different pore size, water-cooled tube inserts the hole, position, upper, middle and lower of different heights, and can need according to moulding process and the change of product warpage quality state, relative position in the horizontal direction between dynamic conditioning water-cooled tube and sheet glass, reach and different cooling and shaping effects is applied to sheet glass, the falling temperature gradient of sheet glass on forming furnace current direction is accurately controlled, is convenient to effectively improve and improve shaping warpage quality taste.
Further, in water-cooled tube position adjustment, the graduation position of the graduated scale that the water-cooled tube mark line of water-cooled tube end is corresponding changes thereupon, can the size of sheet glass distance change in the relative stove of accurate recording water-cooled tube.
Further, after adjusting to the right place in water-cooled tube position, utilize the gap between shutoff tampon shutoff water-cooled tube two ends and waist shaped hole, prevent body of heater from leaking out and leak red, to ensure the stable of molding device running status and quality product grade.
