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 standard earth-boring rock bit or a hybrid-type 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. These systems and methods can be applied to hardfacing steel teeth of the rolling cutters of both standard tri-cone or di-cone type rolling cone bits, as well as to hybrid-type earth boring drill bits.
摘要翻译：本发明涉及一种用于自动化或“机械地”施加表面硬化到标准钻地岩石钻头或混合型岩石钻头的钢齿切削表面的系统和方法。具体地说，该系统包括安装在机器人手臂上的接地的适配器板和卡盘，用于抓住和操纵位于电子或光子能量焊接源下方的岩石切割器，例如由定位器操纵的等离子弧焊炬。在这种配置中，当切割器沿着用于分布堆焊的目标路径相对地操纵时，焊炬基本上竖直定位并且沿着水平轴线摆动。将切割器移动到割炬下方可以覆盖更多区域的更多牙齿，并且可以实现卓越的操作反馈位置，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。控制系统在传感器数据的帮助下操纵机器人手持切割器，同时控制割炬的操作和振荡。这些系统和方法可以应用于表面标准三锥或双锥型滚锥钻头的滚刀的硬齿面以及混合型地钻钻头。

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： Hardfacing (31) is applied on the gage surface (20) of bit blades (19), the leading and trailing edges of bit blades, and on carbide inserts (25). The gage surface contains natural diamonds, synthetic diamonds, thermal stable polycrystalline (TSP) diamonds and carbide inserts, and the hardfacing is applied over at least a portion of them. As the primary cutters on the bit blades are worn down during drilling, the gage surface of the bit is also worn down. A hardfacing is applied to the worn gage surfaces of the bit, thereby allowing the bit to drill deeper and longer without requiring replacement.
摘要翻译：表面（31）施加在钻头刀片（19）的刀表面（20）上，刀刃的前缘和后缘以及硬质合金刀片（25）上。表面含有天然金刚石，人造金刚石，热稳定多晶（TSP）金刚石和硬质合金刀片，并且其表面硬化应用于其至少一部分。由于钻头上的刀片上的主要刀具磨损，钻头的表面也磨损。表面硬度应用于钻头的磨损表面，从而允许钻头钻更深更长而不需要更换。

摘要： An earth-boring bit has rotatable cones with rows of carbide elements installed thereon. A nose is symmetrically arranged on a cone axis of one of the cones. The nose has a central core that protrudes outward. A base joins supporting metal of the cone. A free end is opposite the base. Teeth are formed on the cone between the base and the free end, the teeth extending radially outward. A hardfacing layer is located on the teeth. Intermediate hardfacings extend outward from the core between each of the teeth. The intermediate hardfacings may be lugs and preferably extend the same distance from the core as the teeth.
