一种孕镶金刚石绳索取芯地质钻头及其制作方法技术

本发明专利技术公开了分层分级内锥型,对称内八字前束,漩涡式定心导向的一种孕镶金刚石绳索取芯地质钻头的唇面、钢体连接面及其制作方式，包括金刚石钻头的工作层，钻头钢体，中间隔离水口料、连接层料。本设计钻头整套刀头的组装配置,以配对每对刀头为内八字成型方式,刀头配对配方阴阳分层对称平衡,定位排列入座构成内锥型,刀头分层分布预设同步递减的势态，构成软硬兼施的预设功能,唇面漩涡式保锥八字型(预设八字型是钻头动态着陆的瞬间平衡缓冲和同步补偿到位),持续获得漩涡式导向定心力,持续漩涡式导向定心力就是八字前束概念。关于前束,是把持前进中的有效约束,在钻探钻头的应用中,需要把持孔径垂直的有效纬度,以八字垫定前束而把持定心导向为首要关键。

Diamond impregnated rope core geological drill bit and manufacturing method thereof

The invention discloses a hierarchical cone type, symmetric character before the beam, labial surface, steel body connecting surface and making a diamond rope vortex centering guiding coring drill working layer including geology, diamond drill, drill steel body, nozzle material, intermediate isolation layer material connection. The whole assembly configuration design of drill cutter head, the cutter head is turned in each pair forming mode, the cutter head matching formula layered symmetrical balance of yin and Yang, the alignment seat consisting of a cone type situation knife head layered distribution of default synchronization decreasing, constitute the default function act tough and talk soft lip surface, vortex type cone type (default character the character type is instantaneous balance buffer bit dynamic landing and synchronous compensation in place), sustained vortex type guide centering force, continuous vortex type guide centering force is character before the concept of beam. About the front beam is the effective restraint in the advance, and in the drilling bit application, it is necessary to control the effective latitude of the vertical aperture.
