Embodiment Construction

[0019] see figure 1 and figure 2 The carcass 3 is sintered on the top of the steel body 4 by cold pressing and hot pressing. The carcass 3 is composed of hard-wearing layers 1 and easy-wearing layers 2 arranged coaxially and radially alternately. The wear layer 1 and the carcass 3 are evenly divided into a plurality of wing blocks 6 by water guide grooves 7 . The material of the wear-resistant layer 1 is diamond + the first metal powder, and the material of the easy-wear layer 2 is the second metal powder or diamond + the second metal powder.

[0020] see figure 1 , figure 2 and image 3 , during the entire drilling process, the tile-shaped hard-wear layer 1 of the matrix 3 cuts and drills the rock surface, while the tile-shaped easy-wear layer 2 is worn by the rock surface, and the lip surface of the drill bit will appear serrated 5, correspondingly Multiple rock ridges are formed on the surface of the drilled rock formation to form multiple free surfaces, which "fit" ...

Abstract

The present invention discloses one kind of geological bit. The geological bit has carcass, which is sintered onto the top of steel body via cold pressing and hot pressing process, is constituted with coaxial and radially alternately set hard-to-wear layers and easy-to-wear layers including the outmost and the inmost hard-to-wear layers, and is divided with the water channels into several winged blocks. The present invention also discloses the making process of the geological bit. The geological bit has high efficiency, high quality stability, simple structure, easy manufacture, and reliable performance.

Description

technical field [0001] The invention relates to a drill bit, in particular to a geological drill bit, and also relates to a manufacturing method of the geological drill bit. Background technique [0002] At present, the hot-pressed diamond-impregnated drill bit process is still mainly used in the production process in the 1980s, and there are certain limitations in quality stability. According to the shape of the end face of the carcass, it can be roughly divided into flat tooth drill bits and concentric tooth drill bits. The main disadvantages of flat-tooth drills are low drilling time and poor quality stability; concentric-tooth drills have poor quality stability and high aging at the initial stage of drilling, but after the concentric teeth are consumed, the aging is the same as that of flat-tooth drills. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a geological d...
