A kind of processing method of cemented carbide tooth of mining drill bit

Abstract

The invention relates to a method for processing cemented carbide teeth of a mining drill bit, comprising a bottom plate, a placing device, a grinding device and a polishing device. device. The present invention can solve the problem that the existing equipment can only perform grinding and polishing on a specific arc surface when polishing and grinding the cemented carbide teeth of the drill bit, and cannot perform corresponding polishing according to the radian of the arc surface of the alloy tooth of the drill bit and the inclination angle of the arc surface. Adjustment, there is a gap between the equipment and the arc surface, which reduces the applicability of the equipment. At the same time, usually only the surface or arc surface of the drill bit can be polished separately, and the surface and arc surface of the drill bit cannot be polished at the same time. , and cannot quickly change sides after one side of the drill bit is ground and polished, thereby reducing the rate of grinding and polishing of the drill bit surface.

Description

technical field [0001] The invention relates to the technical field of mine drilling, in particular to a method for processing cemented carbide teeth of a mine drill bit. Background technique [0002] In the coal mine drilling process, the drill bit is the main tool for breaking rocks. The wellbore is formed by the drill bit breaking the rock. The carbide teeth of the drill bit are the key to drilling. The drill bit is the main component of the drilling equipment. Depending on the environment, the specifications and shapes of the drill bit should also be different. When performing coal drilling work, the drill bit should be selected reasonably and scientifically based on the specific needs and specific design schemes. The carbide teeth of the drill bit should be selected before use Grinding and polishing are required. [0003] At present, the existing equipment usually has the following deficiencies when polishing and grinding the cemented carbide teeth of the drill bit: 1....

[0005] The present invention can solve the problem that the existing equipment can only perform grinding and polishing on a specific arc surface when polishing and grinding the cemented carbide teeth of the drill bit, and cannot perform corresponding polishing according to the radian of the arc surface of the alloy tooth of the drill bit and the inclination angle of the arc surface. Adjustment, there is a gap between the equipment and the arc surface, which reduces the applicability of the equipment. At the same time, usually only the surface or arc surface of the drill bit can be polished separately, and the surface and arc surface of the drill bit cannot be polished at the same time. , and it is not possible to quickly change the side after the grinding and polishing of the drill bit, thereby reducing the rate of grinding and polishing of the drill bit surface and other problems
