Description

Technical Field

[0001] The utility model relates to the technical field of pick production and processing, in particular to a cooling and quenching device for pick production. Background Art

[0002] The pick is an important component of underground excavation and mining equipment. It is installed on a tunneling machine or coal mining machine using a tooth sleeve and a tooth seat for underground excavation, which greatly improves the efficiency of underground excavation and makes the mining process more convenient.

[0003] When the cutting teeth first come into contact with cooling water, the cooling water will vaporize quickly, and the steam will drive the impurities in the water tank into the water spray hood. Over time, it will clog the water spray hood and affect the quenching effect.

[0004] The current Chinese utility model patent with announcement number: CN214422696U discloses a cooling and quenching device for cutting tooth production, which is provided with a baffle, which is rotatably connected to the inner cavity through a pin shaft. The baffle is made of a thin sheet, and the size of the baffle is larger than the diameter of the through hole. When there is no water in the water inlet pipe, the baffle covers the through hole due to gravity, which can effectively prevent impurities in the water tank from entering the inner cavity through the through hole, thereby preventing the through hole of the water spray hood from being blocked, affecting the quenching and cooling effect, and ensuring the rigidity of the cutting tooth.

[0005] In view of the above problems, existing patents have provided solutions, but they cannot cool multiple heat-treated picks at the same time, and cannot ensure the uniformity of the cooling of the picks, thereby reducing the overall work efficiency.
