Abstract
The utility model belongs to the field of automobile toughened glass manufacture and discloses a quenching air grid device for a continuous toughening furnace. The quenching air grid device comprises two air knives, an air nozzle and a framework; the two air knives are of a flat mouth form, are arranged on the framework and are also arranged on the upper surface and the lower surface at the front part of a forming and quenching section. The greater and uniform internal stress is formed by the toughened glass produced by the air grid, so that the impact resistant strength of the glass can be improved and further the effect that toughened glass fragments are uniform is achieved.
Description
Technical field
The invention belongs to tempered glass of automobile and make the field, relate in particular to a kind of continuous annealing furnace quenching air grid device.
Background technology
The ME of making toughened glass with continuous annealing furnace is: former, and--heating--quenching moulding---cooling, prior art are simple tuyere blowing moulding in the quenching moulding process, as shown in Figure 1.The shape of tuyere is prone to cause blast instability, air quantity maldistribution in actual use; Toughened glass local wind occurring presses widely different; Cause inhomogeneous, the middle fragment less than normal, limit portion of the whole fragment of toughened glass of production bigger than normal and the strip fragment arranged; Be easy to produce the self-destruction of toughened glass, also can occur sometimes fragment glass not up to standard (national standard of toughened glass is: the fragment of toughened glass in the square of 50mm * 50mm arbitrarily fragment sheet number at the 40-400 piece).
Summary of the invention
Not good for the quenching molding effect that solves prior art, there is the uneven problem of fragment in toughened glass, and the present invention provides a kind of continuous annealing furnace quenching air grid device, improves toughened glass fragment uniformity coefficient.
The object of the invention is achieved through following technical scheme:
Continuous annealing furnace quenching air grid device of the present invention comprises: air knife, tuyere and framework.
Said air knife is flat mouthful, totally two, be installed on the framework, and be arranged on the preceding upper and lower surface of moulding quenching section.
Said tuyere is set in parallel on the framework, totally 6 is listed as, and air knife framework and tuyere framework are arranged in parallel.
The invention has the beneficial effects as follows that get into the tempering forming area after being heated to softening temperature when former, glass gets into the temperature of forming area generally between 680-720 ℃.If the surface temperature of glass differs greatly, the particulate mass changes in distribution of corresponding fragment is big.After the annealing furnace profiled section is installed quenching air grid device of the present invention continuously; Earlier glass is carried out preparatory tempering at forming area by flat one's intention as revealed in what one says cutter; The glass surface temperature differs and diminishes, and makes glass behind tempering front surface temperature uniformity, get into tuyere blowing quenching again and carries out complete tempering.Toughened glass forms big and uniform internal stress, raising glass resistance to impact shock, thus reach toughened glass fragment effect of uniform.Before not adopting quenching air grid device of the present invention, the toughened glass fragment is generally in 50mm * 50mm scope between the 50-400 piece; Adopt behind the quenching air grid device of the present invention the toughened glass fragment in 50mm * 50mm scope all between the 100-300 piece.
