Glass tempering cools off the tuyere structure of flat air grid
Technical field
The utility model relates to a kind of glass tempering equipment part, specifically is the tuyere structure that a kind of glass tempering cools off flat air grid.
Background technology
Now the structure of the common both at home and abroad flat air grid section of horizontal roller formula glass tempering (tempering cooling section) is referring to Fig. 1 and Fig. 2, the independent pressure aerofoil 2 that is provided with is the structural carbon steel weldment, be installed between adjacent two tuyeres 1 of air grid, be connected by bolt 3 on the front and back end plate of air grid 4, stress equalization when its effect makes different thickness (4-25mm) reach tempering temperature (the about 720 ℃) glass that rigidity is very low to bear high blast chilling and operation (being the tempering cooling) on roller-way, purpose is to prevent that glass is floating in air grid, beat etc., produce planeness (sinuousness, the waveform degree), indexs such as granularity reach related standards, satisfy the toughened safety glass of customer requirements.This presses aerofoil 2 to make trouble is installed, and the manufacturing cost height is difficult for accurately location, and is uneven, influence attractive in appearance, the lower flexure strain that is heated in the use, finished glass quality instability.
Summary of the invention
The purpose of this utility model just provides the tuyere structure that a kind of glass tempering cools off flat air grid, to solve the pressure aerofoil manufacturing installation trouble that prior art exists, the manufacturing cost height, be difficult for accurately location, uneven, influence attractive in appearance, the lower flexure strain that is heated in the use, and finished glass instability quality problem.
The technical solution adopted in the utility model is: comprise and press aerofoil and tuyere, this tuyere is the U-shaped cross section, both sides are provided with open holes at an upper portion thereof, it is characterized in that: be equipped with described pressure aerofoil in the both sides, middle and lower part of described tuyere, this presses aerofoil to form to the both sides of tuyere unfolded flank shape.
Described tuyere and pressure aerofoil adopt 6063 aluminium alloys to make, and are the extrusion structure of one.
Surface at described tuyere and pressure aerofoil is provided with oxidation and processing layer.
The outer end of described pressure aerofoil is provided with towards the hypotenuse of described tuyere bottom inclination.
The utility model has the advantages that: press the tuyere of aerofoil and flat air grid to be designed to one, material adopts 6063 aluminium alloys, and the extruding once shaped is handled on the surface through oxidation and timeliness.It substitutes former pressure aerofoil, has not only overcome former pressure aerofoil manufacturing trouble is installed, and the cost height is difficult for accurately location, and the shortcoming that irregular influence is attractive in appearance has improved the equipment class; But also solved the difficult problem of being heated lower flexure strain in the former pressure aerofoil use and influencing the toughened glass quality.

Embodiment
Referring to Fig. 3~Fig. 5, the utility model comprises the pressure aerofoil 5 and the tuyere 1 of an extrusion molding of one, and this tuyere 1 is the U-shaped cross section, and both sides are provided with open holes 6 at an upper portion thereof.Be respectively equipped with pressure aerofoil 5 to the both sides of tuyere 1 unfolded flank shape in the both sides, middle and lower part of described tuyere.
Described tuyere 1 and pressure aerofoil 5 adopt 6063 aluminium alloys to make, and are provided with oxidation and processing layer (handle through oxidation and timeliness on the surface) on their surfaces.
The outer end of described pressure aerofoil 5 is provided with towards the hypotenuse 8 of described tuyere bottom inclination, helps the guiding and the uniform distribution of air-flow.
The utility model is installed in (referring to Fig. 4 and Fig. 5) on the flat air grid 4 with bolt 7 in use, has saved the pressure aerofoil 2 (referring to Fig. 1) and the relevant web member that are provided with separately in the prior art.Stress equalization when its effect makes different thickness (4-25mm) reach tempering temperature (the about 720 ℃) glass that rigidity is very low to bear high blast chilling and operation (being the tempering cooling) on roller-way, prevent that glass is floating in air grid, beat etc., produce indexs such as planeness (sinuousness, waveform degree), granularity and reach related standards, satisfy the toughened safety glass of customer requirements.
