摘要： An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed. The cap can be used with the belted mold assembly or with a casting assembly known in the prior art.
摘要翻译：一种用于制造井下工具的装置和方法，其降低制造成本并提高工具的性能。带式模具组件包括铸造组件，带组件和中间带。带式模具组件用于制造允许使用更大直径坯料的铸件，其移动更昂贵的铸造材料和使用更小的外径薄壁模具。铸造组件设置在带组件内，并且中间带被装载在铸造组件的外表面和带组件的内表面之间产生的体积中。中间带在铸造过程中为铸造组件提供支撑。任选地，盖可以设置在坯料的顶部上，以防止在粘合剂材料和坯料的上部之间形成冶金结合。这允许多余的粘合剂材料保持高纯度，使得其可以被再加工。盖可以与带状模具组件或现有技术中已知的铸造组件一起使用。

摘要： A down hole tool casting assembly, a gauge ring, and a method for preparing the gauge ring for use within the assembly. The gauge ring includes a bit diameter mold and one or more junk slot displacements extending inwardly from the interior surface of the bit diameter mold. The junk slot displacement includes a first end, a second end, and a junk slot displacement face extending from the first end to the second end. At least one groove is formed within the interior surface of the gauge ring, which alleviates stresses formed within the casting during the casting process. According to some embodiments, at least one groove is formed within the junk slot displacement face. According to some embodiments, at least one groove is formed within the interior surface of the bit diameter mold. Optionally, a pressure absorbing material is inserted into one or more grooves.

摘要： A casing end tool has a mandrel and a body that is defined by a wall having an outer surface and an inner surface opposite of the outer surface. The body is fabricated from crystalline tungsten powder and a binder material. The inner surface includes a set of raised bosses or land structures. The body includes a plurality of blades on the outer surface. Each blade has a plurality of cutters. Blade channels and cutter channels on the blades enhance fragmentation of the body during drill out of the casing end tool.

摘要： A bit mold is milled using a turning stage which forms a base mold component and a base gagering component. Next, a blade milling stage is performed in which the base mold component and base gagering component are milled to define integral junkslot formers separated by blade regions. Lastly, a pocket milling stage is performed in which the blade regions and integral junkslot formers of the base mold component are milled to define a plurality of cutter pockets in primary and perhaps secondary rows. Each cutter pocket includes a seat portion and a face portion. The milling of the pocket milling stage provides, at one or more of the cutter pockets, a facet. This facet is provided in an area about the junkslot former associated with the face portion of the cutter pocket, the face portion having, due to the presence of the facet, a surface for matching a cutter core displacement end surface without voids of a size which would require the use of fill material. The facet is also provided on either side of the pocket associated with the seat portion to avoid the need to clay the sides of the displacement for providing top-loading clearances. The milling process at the pocket milling stage further supports definition of relief and erosion resistance features in the mold.
摘要翻译：使用形成基础模具部件和基部成型部件的转动台铣削一个模具。接下来，进行刀片铣削阶段，其中铣削基础模具部件和基础加工部件，以限定由刀片区域分离的整体型碎石成型机。最后，进行凹槽铣削阶段，其中基础模具部件的刀片区域和整体的小刀形成器被铣削以在主要和可能的第二排中限定多个刀具凹口。每个切割器袋包括座部和面部。凹槽铣削台的铣削在一个或多个切割器凹槽处提供一个刻面。该小面设置在与切割器凹槽的表面部分相关联的碎石形成形体的区域中，面部部分由于小面的存在而具有用于匹配切割器芯位移端面的表面，而没有空隙的大小将需要使用填充材料。小面还设置在与座椅部分相关联的口袋的任一侧上，以避免粘附移位侧面以提供顶部加载间隙的需要。在镗铣阶段的铣削工艺进一步支持了模具中浮雕和耐腐蚀特性的定义。
