Embodiment Construction
[0014] In order to further illustrate the present invention, further illustrate below in conjunction with embodiment:
[0015] A process method for the integration of pick carbide brazing and heat treatment of the present invention is characterized in that it comprises the following method steps: A: blanking; B: die forging; C: machining; D: cemented carbide brazing welding; E: heat treatment; F: surface treatment.
[0016] The process method of the present invention integrates hard alloy brazing and heat treatment of picks, first of all, the brazing quality is greatly improved, and the technical index of heat treatment meets the requirements of working conditions. Technically, the inherent defects of the traditional process are eliminated, and various technical indicators of the brazing quality of the pick products in the industrial production are guaranteed to be greatly improved. Taking the shear strength as an example, according to the national pick standard, the qualifie...
