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 360null. 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的方法和装置，例如铲形钻头。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。
