Abstract: Large, heavy-duty, seamless high-pressure resistant ferrous-metal welding necks and other substantially thick-walled cylindrical articles are forged in such manner as to obtain greatly improved quality, dimensionally, metallurgically and otherwise, by the use in sequence of a certain combination of metal-forging elements; which includes a vertically disposed cylindrical female forging die member provided at its bottom with a removable disc and a surrounding circular forging kinfe; an annular metal-working and metal-displacing ring having an external diameter which is slightly less than the bore of the cylindrical female forging die member; a metal-working and metal-displacing disc which interfits with the annular metal-working and metal-displacing ring; a first round forging press follower of a diameter which is adequate to entirely cover the metal-working and metal-displacing disc and a substantial portion of the annular metal-working and metal-displacing ring; a second round forging press follower of a diam

Abstract: An improved method of forming forged socket wrenches in a manner vitiating the need of further machining operation. Steel having a predetermined composition is received in coil form and treated with a lubricating coating. The coiled steel is then straightened and an initial billet of steel is cut to an appropriate size. The billet is then squared to establish opposing longitudinal surfaces in parallel relation with respect to each other and further to provide a working metal billet with a predetermined volume. The metal billet is then positionally located adjacent to a female die in order to provide a bearing surface to form a taper on at least a portion of the external surface of the metal billet.

Abstract: A method of making a disc having integral blades wherein (1) a billet is preformed with the disc being formed close to final shape except that material needed to complete the outer portion including the blades is placed adjacent the outer edge of the preform; (2) the preform dies are changed and the preform is pressed into its final form. The outer die is formed as a two part die having an inner section and outer section, said outer section placing a holding force on the inner formed section and a forming force on the material needed to complete the disc and blades. The blade dies are formed to have a blade cavity longer than the length of the blade desired so that the ends of the blades can be machined to a desired length.

Abstract: A welding electrode made of dispersion strengthened metal wherein the electrode tip is pressure formed or forged to reorientate and/or destroy the coaxial fiber structure and form a non-axial grain structure in the electrode tip portion. The electrode is produced in a method for pressure flowing a blank by applying axial pressure to pressure flow the blank transverse to the axially applied pressure whereby the overall strength of workpieces such as welding electrode rods is substantially increased.

Abstract: A plastic molding process for metal disclosed comprises the steps of: placing a blank within a first female die in contact with the teeth thereof, said female teeth being adaped to define the outer peripheral configuration of said blank, and said blank being supported on top of the female teeth of a second female die placed under said first female die; and then pressing the male teeth of a male die into said blank in a manner that the difference between the radius of a die cushion and the radius (l) of the male die as measured from the center of the male die to the bottom of a tooth groove thereof is equal to or larger than the plastic deformation .delta. of the blank in the radial direction, whereby the blank is molded into a desired shape, without exerting a force on the bottom or the male teeth groove.BACKGROUND OF THE INVENTIONThis invention relates to a plastic molding process for a metal suited for molding a number of teeth at least internally of a blank at a time.

Abstract: The present drop-forging die includes an upper and a lower die member which re pressed together in the forging operation to form a closed cavity of the shape of the finished workpiece without a flash gutter at the interface of the die members. The die is constructed in a manner to force the heated material of the blank to follow a predetermined flow pattern whereby to completely fill the different spaces within the die cavity in a fixed sequence before the material is cooled off enough to cause fabrication defects. More specifically, the material is forced to first flow downwardly to fill a recess in the bottom of the lower die member. Thereafter the cavity elements of the upper die member are filled by a material flow in the opposite direction. For this purpose the blank rests on a narrow annular surface around its bottom edge portion and is mostly unsupported in its center portion above said recess.

Abstract: A die with bevel gear-forming cavity, a punch and a sleeve-like counter punch are constructed for press-forming cylindrical blanks. The punch has a diameter about equal to the circle defined by the intersection of the pitch cone with the low diameter bottom of the die cavity. The counter punch has a frusto-conical projection reaching in the cavity and is held until the die cavity is filled underneath, whereafter the counter punch retracts at a declining speed to fill the remainder of the cavity by radial flow.

Abstract: A method and apparatus are provided for use in converting readily- available steel tubing blanks into components having enhanced mechanical properties suitable for use in pressure vessels and the like, and more particularly the invention provides further apparatus and a method to convert such components into pressure vessel bodies.

Abstract: A cup-shaped blank is extruded through a die onto a cylindrical non-collable mandrel having an external surface pattern counter to a desired internal embossment. Subsequently, the embossed portion of the blank is hydrostatically expanded away from the mandrel to permit removal of the embossed part from the mandrel. The application of hydrostatic pressure to the exterior of the blank during the extruding operation is disclosed.
