CN206174872U 盘刀上具有锥形齿的金刚石钻头 有权

盘刀上具有锥形齿的金刚石钻头
摘要：
本实用新型公开了一种盘刀上具有锥形齿的金刚石钻头，属于钻探技术领域，包括钻头体和盘刀，钻头体上至少设置有一个盘刀，盘刀与钻头体形成转动连接，盘刀的偏移角α的范围是20°≤|α|≤90°，盘刀上至少设置有一颗锥形齿。本实用新型解决现有钻头上的金刚石齿，如PDC切削齿的抗冲击能力较弱，特别是钻遇不均质地层或砾石层时，切削齿易发生齿面脆崩或断齿失效，限制了钻头的使用寿命的问题。本实用新型能够在提高切削齿抗冲击能力的同时，增强钻头的使用寿命和可持续钻进能力。
摘要（英）：

The utility model discloses a last diamond bit who has conical tooth of disc cutter belongs to the drilling technology field, including bit body and disc cutter, be provided with a disc cutter on the bit body at least, disc cutter forms the rotation with the bit body and is connected, and disc cutter's deviation angle alpha's scope is 20 <= | alpha | <= 90, disc cutter is last to be provided with a conical tooth at least. The utility model provides a diamond tooth on the current drill bit, like the shock resistance of PDC cutting teeth a little less than, especially bore when meeting heterogeneity stratum or gravel layer, cutting teeth population's face likely to suffer from is fragile, and collapses or the broken teeth became invalid, has restricted the life's of drill bit problem. The utility model discloses can be when improving cutting teeth shock resistance, the life and the sustainable ability of creeping into of reinforcing drill bit.
