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径向向外的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 “snap-in” bit chuck assembly for a rotary hand or powered tool, includes an elongated body having a hex shank at its rearward end, an elongated retraction collar slidably disposed on the body, and an outer retaining collar fixed to the forward end of the body. The body has a coaxial hex socket formed therein to allow a reversible tool to be inserted thereinto. A slot is formed in the body, between the outer surface of the body and the internal hex socket. A coil spring surrounds the body, inside the retraction collar, and normally biases the retraction collar forwardly and biases a retaining clip toward the bottom of the angular slot. The retaining clip slides outwardly in the angular slot, against the bias of the coil spring, as the reversible tool is inserted, where a recess on the reversible tool is engaged and retained by the clip. The tool is removed by sliding the retraction collar rearwardly, to compress the coil spring and allow the retaining clip to retract back up the slot. The clip is directly engaged by the coil spring and has two legs extending about the body so that the clip is self-retaining. The clip legs extend around the body such that the retraction force on the coil spring is directed through the center of the coil spring to keep it coaxially aligned with the body.

摘要： A tool holder for releasably coupling a bit with a non-circular outer connector surface to a rotary driver. The tool holder includes a socket and a retaining mechanism coupled to the socket and operable in a retaining mode and a released mode. The socket includes a forward end with an opening extending rearwardly from the forward end. The opening also includes a non-circular cross-section adapted to receive the outer connector surface of the bit to couple the bit for rotation with the socket. The retaining mechanism is adapted to permit disposable of the bit into an operative position within the opening and to prevent axial movement of the bit out of its operative position when the retaining mechanism is in its retaining mode. The retaining mechanism is further adapted to permit axial displacement of the bit out of its operative position when the retaining mechanism is in its released mode. The retaining mechanism includes a sleeve coupled to the socket for displacement toward the forward end of the socket from a locked position to an unlocked position thereby moving the retaining mechanism from its retaining mode into its released mode. The retaining mechanism also includes a spring biasing the sleeve into its locked position.

摘要： A "snap-in" bit chuck assembly for a rotary hand or powered tool, includes a body having a hex shank at its rearward end, a retraction collar slidably disposed on the body, and an outer retaining collar fixed to the forward end of the body. The body has a coaxial hex socket formed therein to allow a tool bit to be inserted thereinto. A slot is formed in the body, between the outer surface of the body and the internal hex socket. A coil spring surrounds the body, inside the retraction collar, and normally biases the retraction collar forwardly and biases a retaining clip toward the bottom of the angular slot. The retaining clip slides outwardly in the angular slot, against the bias of the coil spring, as the tool bit is inserted, where recess on the shank of the bit is engaged and retained by the clip. The bit is removed by sliding the retraction collar rearwardly, to compress the coil spring and allow the retaining clip to retract back up the slot. The clip is directly engaged by the coil spring and has two legs extending about the body so that the clip is self-retaining. The clip legs extend around the body such that the retraction force on the coil spring is directed through the center of the coil spring to keep it coaxially aligned with the body. Corners of the clip serve as "stops" for the retraction collar to prevent over-retraction and consequent jamming. The coil spring can be provided with "dead coils" at its ends so it flatly abuts the clip, thus keeping the coil spring and the retraction collar properly aligned. A polymeric cover, preferably formed by a two-step process, is retained on the periphery of the retraction collar.
