Description

Technical Field

[0001] The utility model relates to the technical field of pick production, in particular to brazing equipment for pick production and processing. Background Art

[0002] Pick teeth are a core component in the construction of infrastructure projects such as coal mining, tunneling, pile foundation rotary drilling, and road milling, and play a vital role in the field of national engineering infrastructure. The production process of pick teeth mainly includes machining of the pick body, brazing of carbide teeth, heat treatment of the pick as a whole, and shot blasting of the pick teeth. Among them, brazing the carbide teeth to the steel base of the pick is a crucial step in the processing of the pick body. The brazing quality greatly affects the service life of the pick.

[0003] Most of the existing brazing equipment directly brazes the pick teeth. The pick teeth are transferred from a relatively cold environment to a relatively hot brazing production line, and then directly enter a relatively cold environment after the processing is completed. This will cause cracks to appear on the outer surface of the pick teeth, reducing the yield rate of the pick teeth. In addition, when brazing, the existing equipment needs to take out the brazed pick teeth and then put them back in for brazing, which reduces production efficiency.
