| Penetrators and methods of manufacturing penetrators are disclosed. One method of manufacturing a penetrator having arrowhead geometry and base geometry includes the steps: (a) cold heading a piece of material to form a blank; (b) machining the blank to create the arrowhead geometry; and (c) roll forming the blank to create the base geometry. Another method of manufacturing a penetrator having arrowhead geometry and base geometry includes the steps: (a) machining a piece of material to create the arrowhead geometry; and (b) roll forming the piece of material to create the base geometry. Yet another method of manufacturing a penetrator from a blank includes the steps: (a) machining the blank to create a first surface feature of the penetrator; and (b) roll forming the blank to create a second surface feature of the penetrator. | ||||||

| An automatic swaging machine including a conveyor system for moving tubes into position for swaging a clamping apparatus to secure the tubes adjacent a swaging station to receive a swaging tool releasing a clamping apparatus during the swaging operation, reclamping the tools after swaging to remove the swaging tool from the ends of the tubes and moving the tubes with the conveyor system into a receiving receptacle. | ||||||
| 64 | Method and apparatus for forming parts from a continuous stock material and associated forge | US09953746 | 2001-09-17 | US20020081169A1 | 2002-06-27 | Ronald R.

| 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. | ||||||

| A handling apparatus for forging machines, especially for advancing a wire intended for the manufacture of screws, rivets and the like includes a first cam, keyed on a first motor-driven rotary shaft, cooperating with a first angularly orientable lever, associated with a roller and formed by a branch having a rectilinear portion, oriented parallel with respect to a screw, guided by a support and caused to rotate alternatively clockwise and counter-clockwise either by an electric motor or by hand; a sliding carriage, associated with the screw, provided with a transversal tying pin for an oscillating bar having on its free end a needle that strikes the rectilinear portion of the first lever; a second angularly orientable lever, cooperating with a carriage that is movable in a direction parallel to the direction of advance of the wire; wire grasping means for grasping the wire; a second cam, alternatively mounted on a second shaft or a rotary side shaft of the forging machine, which cooperates with a needle fixed to the lower end of a third lever pivoted on a static support of the forging machine. | ||||||

| 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 a number of discrete parts. The efficiency of the forming process is enhanced since individual parts need not be individually transported and oriented during the forming operations. By not requiring that the individual parts be separately transported and oriented during the forming operations, the quality of the parts formed by the forming method and apparatus of the present invention will also be enhanced since such separate transportation and orientation of individual parts generally increases the opportunities for misalignment and contributes to poor tolerance control during the manufacturing process. | ||||||
| 67 | Apparatus for the continuous shearing off and cold swaging of metal workpieces | US726888 | 1985-04-24 | US4866970A | 1989-09-19 | Albino Castiglioni |
| Apparatus for the continuous shearing off and cold swaging of metal workpieces, particularly wire material, comprises a device (1') for feeding the material (5), a pivotable shearing device (2), a slide (1) for swaging the sheared-off part, and a die-studded chuck (31). These components are arranged so that they are distributed in the machine frame (11) along the sides of a U. These components can all be driven by a motor (4) via a conventional drive. Feeding of the material (5) in the direction of the chuck (31) takes place with intermittent motion and in synchronism with the movements of the described components of the machine. The production output of finished parts is greatly increased by the chosen arrangement, the intermittent feeding of the material, and the pivotability of the cutter. The slide has a holder (37) for a plurality of tools in sockets (43, 44, 45 or 43', 45'). These sockets, and the axis of the material, lie on an imaginary circle that is of the same diameter as and coaxial with an imaginary circle on which the dies (30) on the chuck lie. Each of those sockets, and the material, is aligned with a respective one of the dies in every stopped position of the chuck, so that a tool held by the slide will strike a shorn-off workpiece every stroke of the slide. | ||||||

| A device for feeding wire stock of fixed length to a cutoff tool in a linear and continuous manner by means of the reciprocating motion of a wire cutting mechanism driven by an eccentric shaft being utilized to sever and sequentially feed the cutoff wire stock one at a time to a die head. | ||||||
| 69 | Method and apparatus for feeding discrete parts to a cold heading machine | US3666160D | 1970-06-30 | US3666160A | 1972-05-30 | GWYN CHILDRESS B JR |
| The machine is described with reference to the production of cold bonded composite electrical contacts. A cold heading machine is altered to permit contact facing material to be fed into the coning punch assembly in discrete pieces such as balls, cylinders or the like. Ordinarily, pieces severed from a wire feed are delivered directly to the header die. In the present invention, the coning punch acts as a carrier of this material to the header die. The preferred apparatus is inherently self-timing, loading the contact facing material into the coning punch at its ''''rest'''' position. Optionally, individual body and facing components may be initially bonded as by brazing, and fed to the cold heading machine by the apparatus of the invention, eliminating wire feed and severing entirely. By virtue of the invention, facing and body components need not be of the same diameter, coning shapes are optimized, and a larger variety of heading diameters, facing thicknesses and heading ratios may be obtained. Stronger interfacial bonding is also achieved.

| For the advancing or feeding motion of bars, wires or the like up to now in most cases two hydraulic devices were used, one for gripping the rod and the other for moving it. According to the invention, to make the apparatus more simple, one single hydraulic cylinder is used for this purpose and according to one embodiment of the invention the piston moved in the hydraulic cylinder actuates at the beginning of its stroke the gripping means and thereafter it shifts this gripping means together with the rod or other workpiece; according to another embodiment the piston is used only for the moving or feeding but the gripping is produced by a series of rings actuated by the same hydraulic fluid which acts on the said piston.
