摘要： A shank configuration for rotary drill bits is disclosed for positioning of the shank in relation to the bit body. A tapered surface or feature of the shank may be configured and sized to matingly engage a complementarily shaped surface or feature of the drill bit body and thereby become centered or positioned in relation thereto. A deformable element may be disposed between the shank and bit body. Also, the shank may comprise a material having a carbon equivalent of less than about 0.35%. A multi-pass weld procedure may be employed to affix the shank and bit body to one another wherein welds may be formed so that one weld originates at a circumferential position that differs from the origination circumferential position of its immediately preceding weld by at least about 90°. Further, a stress state may be developed within the multi-pass weld. A method of manufacture is also disclosed.

摘要： Earth-boring tools such as, for example, earth-boring rotary drill bits include erosion-resistant structures disposed proximate areas of intersection between faces of the tools and fluid nozzle recesses or fluid passageways extending through the tools to the face. In some embodiments, such an erosion-resistant structure may comprise a mass of hardfacing material. In additional embodiments, such an erosion-resistant structure comprises an erosion-resistant insert. Methods of forming such earth-boring tools include providing erosion-resistant structures proximate intersections between the faces of the tools and fluid nozzle recesses or fluid passageways extending through the tools. Methods of repairing earth-boring tools include providing an annular-shaped, erosion-resistant structure over an eroded surface of a body of a previously used earth-boring tool proximate an intersection between an outer face of the body and an inner surface of the body.

摘要： The present invention relates to a system and method for automated or “robotic” application of hardfacing to the surface of a steel-toothed cutter of a rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction. The control system, aided by data from the sensors, manipulates the robotically held cutter while controlling the operation and oscillation of the torch.
摘要翻译：本发明涉及一种用于自动或“机械地”将耐磨面施加到岩石钻头的钢齿刀具的表面的系统和方法。特别地，该系统包括安装到机器手臂的接地适配器板和卡盘，用于在电或光子能量焊接源（例如由定位器操纵的等离子体电弧焊炬）之下抓取和操纵岩屑钻头。在这种配置中，当切割器相对于目标路径被操纵以便分配表面硬化时，手电筒基本垂直地定位并且沿着水平轴线摆动。在割炬下方移动切割刀允许更多的牙齿区域被覆盖，并且允许优异的布置用于操作反馈，例如自动定位和参数校正。在优选实施例中，传感器向控制系统提供用于识别，定位，焊接程序选择和焊接程序校正的数据。控制系统由传感器的数据辅助，在控制手电筒的操作和振荡的同时，操纵机器手柄。
