61 Tool for removing damaged fasteners and securing new fasteners and improved method for making such tool US10225727 2002-08-22 US20030056622A1 2003-03-27 Chalmer C. Jordan
A tool for removing damaged fasteners and a method for making such tool wherein the tool (10) includes a first end (12) and a second end (14) with an outside surface (32) and an inside surface (40) defined between ends (12) and (14). A portion (46) of inside surface (40) is in the shape of a hexagonal frustum (54) that has a major end (58) and that includes spiral splines (25). Splines (25) have constant depth between the major end (58) and the minor end (56) of frustum (54) and the relief angle (null) of splines (25) increases in the direction from minor end (56) toward major end (58). In the method for making the tool (10), a tubular section (118) is made from a tapered blank (91) by piercing one end of the tapered blank with a pierce punch (132). One end of the tubular section is then driven onto a splined punch (162) to provide a splined tubular section (165) having splines in one end. The splined tubular section is then stripped off of the punch (162) by a kick-out sleeve (166) and extruded through a round-to-hexagonal extrusion insert (182) to provide a splined polygonal section (173) having an inner surface with a tapered, hexagonal shape. A modified round-to-hexagonal extrusion insert (206) provides a tool with corners (202) on the polygonal surface. A modified tool (310) with splines (325) in a clockwise spiral is used to secure tamper-resistant fasteners. The modified tool (310) is made by substituting a clockwise splined punch (462) in the tool-making method.

The object of this invention is to propose a manufacturing method for manufacturing component part for the variable capacity turbine, and the structure of the nozzle driving member, which will simplify the structure of the component part for the adjustable nozzle mechanism, the manufacturing work which results in lowering the manufacturing count and cost, as well as the number of component part, and in lightening the weight of the variable capacity turbine. In order to manufacture the component part for a radial-flow variable capacity turbine, in which the actuating gas is forced to flow from a spiral scroll formed in the turbine casing to a turbine rotor in a radial direction, through multiple nozzle vanes of which the angle is adjustable by an adjustable nozzle mechanism, for rotating the turbine rotor, this manufacturing method according to this invention is distinguished by the configuration in which a column shaped connecting pin is formed as a single structure with a plate member by a pressing, or a precision molding by partially forcing the surface of the plate member to protrude in a column shape.
63 Method of forming a one-piece steering shaft member US09643416 2000-08-22 US06257041B1 2001-07-10 James A. Duggan
A method for forming a one-piece steering shaft member, such as an externally splined male steering shaft member (or yoke shaft) or an internally splined female steering shaft member (or slip yoke) is disclosed. A hollow cylindrical tube is initially provided which is preferably formed from a blank of a metallic material, such as aluminum, having an elongation factor of at least fifteen percent. It is desirable that the tube have a uniform wall thickness and define an outer diameter which is substantially uniform along the length thereof. The outer diameter of one end of the tube is reduced from its original diameter while the outer diameter of the opposite end is maintained at its original diameter. A splined surface is formed in the reduced diameter end portion of the tube. The splined surface is formed on the external surface of the yoke shaft and on the internal surface of the slip yoke. A yoke member is then formed in the opposite end of the tube. In one embodiment, the opposite end of the tube is first deformed so as to provide a generally hollow rectangular cross sectional shape. Generally U-shaped portions of material are removed from two of the opposed sides of the hollow rectangular end of the tube to form a pair of opposed yoke ears adapted for use in a universal joint. In a second embodiment, the opposite end is maintained in its original hollow cylindrical shape and is machined to form the opposed yoke arms. In both embodiments, a bore is formed through each of the yoke ears.

67 Base plate for suspension assembly in hard disk drive with tapered inner barrel US931804 1997-09-16 US6033755A 2000-03-07 Kevin Hanrahan; Ryan Schmidt
A base plate wherein the inner barrel of the base plate hub is comprised of two distinct zones. The first zone is an inner diameter sized for use with standard tooling pins in an assembly process as a metric for size control. The second zone is a taper for distributing tension swage force and plastic strain toward the rear part of the hub by making the hub stiffer as the swage ball proceeds downward through the barrel, and for distributing compression swage force and plastic strain toward the rear of the hub by relieving stiffness as the swage ball proceeds upward. A back side slope is provided to prevent washed metal from creating added swage force and plastic strain during swaging in the compression direction. The base plate has a minimal counter bore, a lead-in chamfer which is shallower than typical, a second lead-in chamfer which is very steep and upon which the ball begins to swage, a small inner diameter region to allow for tooling during assembly, and a tapered backside to reduce unneeded material.

70 Method for forming a lightweight flanged axle shaft US960015 1992-10-13 US5213250A 1993-05-25 Joseph A. Simon
A method for forming a lightweight flanged axle shaft particularly for use within automotive vehicles for transmitting power from a power source, such as the differential, to a driven wheel. The method includes extruding a tubular blank through a die throat by pushing the blank through the die throat and causing the blank to collapse inwardly around a mandrel-like member located within the die throat to thereby form an elongated, thin wall, hollow tube. A flange member, which is separately stamped out of metal, is formed with a disk-like flange and an integral central tubular-shaped hub whose free edge is of approximately the same diametrical size and thickness as the end of the shaft. The flange hub and the shaft end are welded together, face to face, by engaging the two and rapidly spinning one relative to the other to generate sufficient heat to fuse them together upon discontinuance of the rotation. This produces a one-piece, long, hollow, thin wall, lightweight, hollow shaft with a hollow flange having a hollow flange hub integrated with the shaft end. The opposite end of the shaft is configured, such as with spline teeth, for fastening that shaft end to a drive or driven member while the flange at the opposite end of the shaft is fastened to the opposite drive or driven member.
71 Method of making a tubular member US746177 1991-08-15 US5088311A 1992-02-18 Kiyoshi Inoue
In a method of making a metallic shell for a glow plug, a columnar blank is extruded to have an enlarged recess on the upper end surface of the blank so as to make an upper tubular portions, while extruded to have an enlarged recess on the lower end surface to make a first tubular end circular in section, an outer diameter of which is smaller than that of the upper tubular portion. The blank is transferred without inverting it, and the blank is reduced at its upper tubular portion to make a second tubular end hexagonal in section, an outer diameter of which is smaller than that of a middle portion of the blank, but greater than that of the first tubular end. Then, the blank is transferred without inverting it, and punched to communicate the first tubular end with the second tubular end by means of an axial bore. In other method, a mandrel is forced into the upper tubular portion to form a second tubular end hexagonal in section, an outer diameter of which is smaller than that of a middle portion of the blank, but greater than that of the first tubular end. In the forcing process, a cooling liquid oil is supplied between the upper tubular portion of the blank and the mandrel to alleviate friction heat, the cooling liquid oil flowing down between the upper tubular portion of the blank and the mandrel is led to the axial bore as an escape path of the liquid oil.
