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...

Description

technical field [0001] The invention relates to a process method integrating hard alloy brazing and heat treatment of picks. Background technique [0002] The pick-shaped pick of coal mining machine and roadheader is a very important part of fully mechanized mining equipment in coal mines. Its performance directly affects the mining efficiency. The comprehensive stress conditions of extrusion, shearing and impact generated under light, medium and heavy working conditions make the working environment very harsh. Poor quality of hard alloy brazing, low weld shear strength, unstable heat treatment performance and other problems that have plagued my country's pick industry for a long time are an important factor causing high mining costs in my country. Contents of the invention [0003] In order to solve the above-mentioned existing shortcomings, the main purpose of the present invention is to provide a practical method for the integration of hard alloy brazing and heat treat...
