Abstract
The utility model discloses a to cool down cooling structure of tempering of high temperature glass, its characterized in that: including rollgang and the cooling module who carries glass, cooling module including cooling air knife soft breeze bars, cooling module be two sets of, the rollgang place in between two sets of cooling module, and the glass of how much axial direction that cool off the air knife and rollgang to transport the orientation perpendicular. Adopt the setting in top air inlet cooling air grid structure and a plurality of defeated wind gaps, can make the glass cooling more even. Through the perpendicular glass surface from top to bottom of using of aperture of air knife lower part, focusing on the position in the middle of the cooling air grid to the cooling air after the secondary equilibrium, reaching even refrigerated purpose, tempering glass's quality has still been improved greatly to the while.
Description
Technical field
This utility model relates to the cooling structure that high temp glass carries out in ultra-thin safety glass production process cooling tempering.
Background technology
The product of safety glass is widely used in various fields such as building, aviation, automobile, steamer, locomotive, electron display devices.Safety glass obtained Section 1 patent from 1870 in France to be begun, and obtains several patents in 19th-century, and was industrially applied in 1892.A series of products such as flat safety glass, curved tempered glass are developed afterwards, to the 1980s, increase along with glass new varieties, safety glass process industry has carried out the R and D of new product, at the low emissivity glass tempering of building energy conservation window, the large-scale and different in nature glass tempering etc. of vehicle glass has considerable progress.Physical toughened glass is to form compressive stress layer at glass surface, makes its one prestressing force of increase to improve strength of glass, and be widely used at present is quick air cooling tempering (being called for short air hardening steel) method.Air hardening steel is that glass is heated to more than glass tempering transition temperature (Tg) 80 DEG C, use air as cooling medium, quickly glass surface heat is taken away, glass outer cooling is very fast, and center of glass is to be cooled down by conduction of heat by glass outer, therefore center of glass is slower relative to what glass outer layer cooled down, then pass through this process and create internal stress at glass outer layer and core, and the comprcssive strength of glass is more than ten times of its tensile strength, by the introducing of internal stress, add the tensile strength of glass, make the intensity of glass be improved.And structure of its cooling is complicated in present air hardening steel, and air cooling is the most uniform, and then causes the situation that its glass bursts.
With reference to accompanying drawing 3, cooling air grid the most currently on the market is all from rear portion, side air inlet mode, there is bigger stress extreme difference in the glass surface completed after tempering, the bad control of glass flatness, the self-destruction rate of safety glass is the highest simultaneously, although rear portion air inlet mode simple in construction, but before and after there is air knife there is blast problem of non-uniform in two ends；Also can be greatly improved the self-destruction rate of safety glass, cause damage.
Utility model content
For the deficiency of prior art existence, the purpose of this utility model is to provide a kind of cooling uniformly, and the blast in cooling air knife carries out the cooling structure of cooling tempering uniformly to high temp glass.
For achieving the above object, this utility model provides following technical scheme: the cooling structure of a kind of tempering that carries out high temp glass lowering the temperature, rollgang (900) and cooling assembly including conveying glass, described cooling assembly includes cooling down air knife (600) and air grid (500), described cooling assembly is two groups, described rollgang (900) is placed between two groups of cooling assemblies, and the geometry axial direction of cooling air knife (600) is vertical with the glass carriage direction of rollgang (900).
This utility model is further arranged to: described air grid (500) is placed in the vertical direction of cooling air knife (600), the defeated air port of at least two it is provided with on air grid (500), defeated air port is that axis of symmetry is arranged symmetrically with the central shaft of cooling air knife (600), and cooling air knife (600) is carried out the conveying cooling airflow of Vertical Uniform by multiple defeated air ports.
This utility model is further arranged to: described cooling assembly is connected with point wind bellows (300) by ajutage, and described ajutage includes blast main (700) and the blowpipe (701) being connected respectively with defeated air port.
By using technique scheme, accessible beneficial effect: use top air intake cooling air grid structure and the setting in multiple defeated air port, glass cooling can be made more uniform.By the aperture perpendicular acting of air knife bottom to glass upper and lower surface after secondary equilibrium, cooling wind is focused on the position in the middle of cooling air grid, reaches the purpose uniformly cooled down, the most also substantially increase the quality of safety glass.
