Description

Technical Field

[0001] The utility model relates to the technical field of glass tempering equipment production jigs, in particular to a welding tool for wind grilles. Background Art

[0002] The cold air grille of the glass tempering equipment is composed of a plurality of wind grille bars, a wind shield is installed between two adjacent wind grille bars, and an exhaust gap is arranged between the wind shield and the wind grille bars.

[0003] After the cooling air blown out of the wind nozzle of the cold air grille hits the surface of the tempered glass, it turns back and blows toward the wind shield. The turned back cooling air is distributed through the wind shield and then evacuated to the surroundings from the exhaust gap. Therefore, the board surface of the wind shield between the same group of wind grille bars should be on the same horizontal plane so that the turned back cooling air can be evenly evacuated. If the board surfaces of multiple wind shields are not on the same horizontal plane, there will be a phenomenon of up and down misalignment, which will lead to different evacuation flow rates of the turned back cooling air, making the cooling air blown out of the wind nozzle have uneven wind pressure, thus affecting the quality of glass tempering.
