    摘要： The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360°. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.

    摘要翻译： 本发明提供一种从连续原料形成多个零件，例如铲形钻头的方法和装置。 因此，本发明的成形方法的各个步骤可以在将连续坯料分离成离散部分之前，对连续原料的预定部分进行，从而提高成形过程的效率。 本发明还提供了一种用于将连续坯料的部分形成为具有预定形状的部件的改进的锻造。 锻造可被设计成提供靠近冲头的前端的间隙区域，以允许在锻造操作期间沿径向向外的方向使冲头的前端略微弯曲。 锻造还可以包括用于润滑其各种部件的润滑系统。 此外，锻造可以在锻造一个或多个零件之后逐渐地旋转压头。 通过重复冲压器的增量旋转，锻造将最终使压头旋转360度。 还提供了一种改进的锻造模具，其包括具有圆锥形中间部分的后表面和相对于中间部分凹陷的一对锥形横向部分，使得在锻造操作期间主要将力施加到中间部分。

    摘要： A tool includes first and second elongated members, each member having a handle portion at one end and a jaw portion at an opposite end. Intermediate portions of the members are movably coupled to one another. Movement of the handle portions opens and closes the jaw portions. Each jaw portion includes a gripping surface configured to grip a workpiece. A pair of blade members are rigidly secured to the jaw portions, each blade member having a cutting edge.

    摘要： A cutting tool (200, 202) has a longitudinally extending shaft portion (208) with a chucking part (204) and a cutting head (206). A cutting edge (220) is formed on the cutting head (206). The cutting edge (220) includes at least one cutting portion. A rake surface (224) is formed adjacent to at least one of the cutting portions (220) with the rake face being at a rake angle in the range from about −10° to about 10°. A clearance face (226) is formed adjacent to the at least one cutting portion opposite the rake face (224). The clearance face (226) is at a clearance angle in the range from about 10° to about 50°. An edge radius between the rake face and the clearance face is at a radius of from about 0.0003 to about 0.0040 inch.
