一种含有高锰钢锥的金刚石钻头

Diamond bit who contains potassium steel awl

Abstract

The utility model discloses a diamond bit who contains potassium steel awl, including the steel body, matrix, mole, the steel body coupling the matrix, the matrix is the loop configuration, the mole spacer ring to set up being in the matrix on, the mole include that diamond base member and a plurality of wear to locate the potassium steel cone in the diamond base member, the setting of potassium steel cone circular cone head protrusion be in mole surface. In this way, the utility model discloses a when diamond bit creeps into, potassium steel cone evagination, thereby the area of contact of diamond bit lip face with the rock has been reduced, the pressure that makes the lip face apply for rock unit area increases, diamond bit is to the pressure increase of rock, and simultaneously, when potassium steel receives impact load, plastic deformation takes place and forms the work hardening phenomenon for the surface, make surface hardness increase substantially, its abrasion resistance reinforcing, change the fractured rock, drill bit drilling speed improves, the problem of medium hard to hard rock stratum diamond drilling speed slow is solved.
本实用新型公开了一种含有高锰钢锥的金刚石钻头,包括钢体、胎体、胎块,所述的钢体连接所述的胎体,胎体为环形结构,所述的胎块间隔环向设置在所述的胎体上,所述的胎块包括金刚石基体和若干个穿设于金刚石基体中的高锰钢锥体,所述的高锰钢锥体圆锥头部凸出设置在所述的胎块表面。通过上述方式,本实用新型的金刚石钻头钻进时,高锰钢锥体外凸,从而减小了金刚石钻头唇面与岩石的接触面积,使得唇面施加给岩石单位面积的压力增加,金刚石钻头对岩石的压强增大,同时,高锰钢受到冲击载荷时,表面发生塑性变形而形成加工硬化现象,使得表层硬度大幅度提高,其抗磨性能增强,更易破碎岩石,钻头钻进速度提高,解决了中硬至坚硬岩石地层金刚石钻进速度慢的问题。
