Description

Technical Field

[0001] The utility model relates to the technical field of air cooling tables, in particular to an air outlet mechanism of a uniform air type steel ball salt quenching air cooling table. Background Art

[0002] Salt quenching of steel balls is a processing method that uses salt bath heating and quenching. In the production and processing of steel balls, salt quenching is widely used. This quenching method can make the steel balls reach the ideal hardness and wear resistance, and improve their service life and performance. After quenching, the steel balls need to be cooled, and generally an air cooling table is used. The air cooling table is connected to a fan and the air flows evenly through the outside of the air-cooled workpiece, thereby taking away the heat of the workpiece itself to achieve the purpose of rapid cooling.

[0003] A common air cooling table generally consists of a cooling table and an air outlet mechanism. When working, steel balls are placed on the surface of the cooling table, and then the steel balls are cooled by the fan. However, since the table top of the air cooling table is mostly flat, the wind direction of the air outlet is mostly parallel. This wind direction can quickly cool the standard workpiece, but when cooling the steel balls, the parallel wind direction cannot cool the steel balls well, which will cause the cooling speed of the steel balls in the middle to be slower than that of the steel balls on the periphery. At the same time, due to the shape limitation of the steel balls, they need to be adjusted during cooling. However, since the surface temperature of the steel balls is too high and the number is large, it is inconvenient to adjust, which reduces the cooling speed of the air cooling table and cannot meet the working requirements of the air cooling table. Therefore, an air outlet mechanism of a uniform wind type steel ball salt quenching air cooling table is proposed. Utility Model Content
