Abstract: A forging punch of the present invention includes: an outer punch of a cylindrical shape; and an inner punch disposed in the outer punch and protruding from an end surface of the outer punch; at least one of the punches having at least one groove for relieving oil formed either on an inner peripheral surface of the outer punch or on an outer peripheral surface of the inner punch. Therefore, an oil remaining between the end surface of the outer punch and the bottom surface of a workpiece is relieved to the outside of the forging punch by way of the groove, thereby enabling precise forging. Further, the forging punch has obviated additional processing, because no traces of the groove are marked on the workpiece after processing.

Abstract: A hand tool of the pliers-type configuration used for crimping electrical terminals is disclosed. The tool includes a pair of jaws movably with respect to one another by the actuation of a pair of handles. The jaws define a crimping nest which supports an electrical terminal. One die of the crimping nest includes a raised surface, and depending tapering side walls. The raised surface of the die has an hour-glass configuration. The particular shape of the die limits the pressure applied to the terminal during crimping, so as to reduce the tendency to overcrimp the terminal.

Abstract: A method and apparatus for the solid-state forming of a metallic feedstock into thin sheet or foil is disclosed that uses improved isothermal roll forging techniques. The improvements include the use of rotatable backup rolls for increasing hollow work roll stiffness, two independent work roll heating controllers, a reduced work roll diameter and other means for precise control of conditions within a feedstock "travelling hot zone" (THZ). The disclosed improvements allow the application of isothermal roll forging techniques to the rolling of thin sheets from difficult-to-work, high-strength metals such as aluminides, intermetallics, superalloys, titanium alloys, ODS composites, beryllium, and others in sheets having widths of 24-inches and more.

Abstract: A method and an apparatus for bending pipes by clamping one end of the pipe between a formed roll and a rotary base and by turning the rotary base so that the pipe may be bent along the outer periphery of the formed roll. A mandrel supported by a mandrel bar is arranged inside the pipe at a position corresponding to a position slightly behind where the pipe is clamped between the formed roll and the rotary base. The rear end of the mandrel bar is held in place by a pressurizing device so that the mandrel can be held fixed at said predetermined position inside the pipe. At the same time, a vibrating device attached to the mandrel bar causes the mandrel to continuously reciprocate in the axial direction of said mandrel bar, whereby flattening of the pipe which occurs when the pipe is bent along the outer periphery of the formed roll can be corrected by the reciprocation of the mandrel. As a result, the radius of curvature R of the pipe can be made smaller than R=3D, where D is the diameter of the pipe.

Abstract: A method and apparatus for draw forming a metal sheet over a male form to produce a three-dimensional shape. A sheet of metal is clamped between upper and lower draw plates positioned above the male form. The upper plate has an edge conforming to the male form shape. The plates and sheet are moved downwardly over the form with the edge of the upper plate firmly pressing the sheet against the form. The clamping pressure between the draw plates allows suitable slippage as drawing proceeds to produce a drawn shape of intended thickness. The drawn shape has a configuration conforming to the outer surface of the male form and has an outer surface of improved uniformity and appearance due to the wiping action of the upper plate edge.

Abstract: The installation comprises a press (2) having a press ram (22) which is driven by a drive electric motor (26), to drive an applicator ram (47) of an electrical terminal applicator (44). A control circuit arrangement (89) controls the drive motor (26) so that the press ram (22) is brought at least substantially to its top-dead-center, home position after each press cycle and also has sensors (140 and 142) for sensing the absence of a terminal (T) from a strip (S) and of terminals (T) fed to the applicator (44), to cause the press ram (22) to carry out an extra cycle to place the next following terminal (T) on the anvil (58) of the applicator (44). The control circuit arrangement (89) controls a lead making machine (114) which includes the applicator (44); and performs various other control functions.

Abstract: A press ram (6) is coupled to an applicator ram (20) to drive it, by means of a claw (54) which engages beneath an adaptor head (34) on the applicator ram (20). The claw (54) is formed on a slide (46) which is vertically shiftable in a guideway (42) in the press ram (6), the position of the slide (46) in its guideway (42) being adjustable by means of adjustment screw (62) from which projects eccentrically, a spigot (66) which engages in a slot (50) in the slide (46). The adjustment screw (62) can be rotated by means of a tool blade (B) to raise the slide (46) to take up slack between the press ram (6) and the applicator ram (20). A set screw (74) is provided for securing the slide (46) in its position of adjustment.

Abstract: A guide arrangement for a door element (14, 16), particularly a sliding door element for a shower enclosure, includes a guide element (10, 12) at the bottom edge of the door element including a rotatable member (34) engaged with a guide channel (8) of a lower guide rail (2). The guide element can be disengaged from the guide rail, when desired. The rotatable member (34) is at least partially mounted in a transverse hole (35) in a holding body so as to be at least partially rotatable about an axis of rotation extending substantially perpendicular to the plane of the door element (14, 16). The rotatable member is additionally provided with an actuator, preferably in the form of a grip (10). The rotatable member (34) carries a pintle (38) which, depending on its rotational position, either engages the guide rail (2) or is pivoted out of engagement with the guide rail.

Abstract: A method and system for nondestructively measuring surface compression layer depth including obtaining profile data of a peened workpiece surface and determining a total plastic upset depth for a selected dent, the plastic upset depth being approximately equal to the dent diameter. The peening operations may then be adjusted, if needed, so that subsequent peening more closely conforms to predetermined, desired peening results.
