| A material member blanked from metal sheet is subjected to upsetting to form an annular peripheral portion that is thinner than the center part of the material inside the annular portion, and the thicker inside portion is formed into a concavity. The first intermediate product thus formed is drawn to form a cup-shaped case with an internal boss and/or an external boss, and an outside flange. The intermediate product can also be used to make gears and the like. | ||||||

| 65 | Thin, forged magnesium alloy casing and method for producing same | US09834602 | 2001-04-16 | US06511560B2 | 2003-01-28 | Isao Seki; Shigeo Hama; Shigehiro Taniike; Fukashi Watanabe; Masahiko Kakizaki; Shinji Seki |
| A thin, forged magnesium alloy casing is integrally constituted by a thin plate with projections on either or both surfaces, and the thin plate is as thin as about 1.5 mm or less. The thin forged casing can be produced by (a) carrying out a first forging step for roughly forging a magnesium alloy plate to form an intermediate forged product under the conditions of a preheating temperature of the magnesium alloy plate of 350-500° C., a die temperature of 350-450° C., a compression pressure of 3-30 tons/cm2, a compressing speed of 10-500 mm/sec. and a compression ratio of 75% or less; and (b) carrying out a second forging step for precisely forging the intermediate forged product under the conditions of a preheating temperature of the intermediate forged product of 300-500° C., a die temperature of 300-400° C., a compression pressure of 1-20 tons/cm2, a compressing speed of 1-200 mm/sec., and a compression ratio of 30% or less. | ||||||
| 66 | Process for manufacturing a captive screw | US301005 | 1999-04-28 | US06086480A | 2000-07-11 | Thomas J. Ellis; Edward A. McCormack; Harry L. Dickerson |
| A method of making a knob and ferrule for a captive screw is disclosed, the knob integrally attached to the screw, the ferrule attachable to a panel. The method of making the knob includes providing an aluminum alloy base metal for the knob, pressing by cold-forming the base material into a generally cylindrical cup-shaped article using at least one pressing operation, the cup having a generally cylindrical side wall, removing any base material situated outside the perimeter of the cup-shaped cylindrical article, and providing a hole in the bottom of the cup, coaxial with the hollow cylindrical walls of the cup, thereby forming the knob. The method of making the ferrule includes providing a metal base material for the ferrule, pressing the base material, by cold-forming, into a cylindrical article using at least one pressing operation, the cylindrical article having a cylindrical side wall having an outer surface, cold-forming an attachment device an end of the ferrule; and removing any base material situated outside the perimeter of the cylindrical article, thereby forming the ferrule. All major parts of the captive screw, including the knob, ferrule and screw may be cold formed. | ||||||
| 67 | Twin-shelled artificial hip joint and its manufacture | US46375 | 1998-03-23 | US6045583A | 2000-04-04 | Walter Gross; Kurt Bider; Jurg Oehy |
| The invention shows a hip joint socket and its manufacture, with the hip joint socket including a thin walled metallic outer shell with anchoring pins which is firmly connected to an inner shell of plastic. Since the bearing surface of the inner shell is not produced until after the assembly, a high accuracy of shape of the bearing surface results together with a relatively elastic outer shell and with good anchoring aids for a primary anchoring. | ||||||
| 68 | Method and system for warm or hot high-velocity die forging | US931761 | 1997-09-16 | US5894752A | 1999-04-20 | Masakazu Yano; Katsuhiko Osaki; Tadatsugu Yoshida; Yoshio Kasahara |
| An axially symmetric ring work piece is formed by a warm or hot, forward and backward extruding, die forging system. In this system, a die having a rearwardly projecting portion, which projects in the opposite direction to a pressing direction, a heated work piece, and a punch having a forwardly projecting portion, are arranged, in that order, in a container. A withdrawal die is arranged between the container, and the heated work piece, the die and the punch. The die is fixed so that a die velocity V.sub.D is 0, and the punch is moved toward the die while a punch velocity V.sub.P is set to be twice as large as a withdrawal die velocity V.sub.WD and the strokes of slide of the withdrawal die are not less than one-half of a forward-extruded foot length of a product. Thus, the forward and backward simultaneous extrusion can be substantially performed in a single-action type, short-stroke, die forging system. In addition, it is possible to effectively and accurately form a ring part, which has good metal flow and no defects, and which has a stable quality, at higher than 80 strokes per minute. | ||||||
| 69 | Method of manufacturing a yoke for an elastic universal joint | US662527 | 1996-06-13 | US5845394A | 1998-12-08 | Shouichi Abe; Kiyoshi Okubo |
| In manufacturing a yoke for an elastic universal joint, the time required for each step is shortened and the automation of each step is made easy, and by the energy saving and high efficiency of the manufacturing work, a reduction in the cost is achieved. A metallic plate is subjected to working which can be done easily and within a short time by press work such as stamping work, deep drawing work and ironing work, to thereby make a yoke for an elastic universal joint. This can be accomplished because welding work and cutting work which require much working time and which are cumbersome to automate can be eliminated. Investment in facilities may be small. | ||||||
| 70 | Bush-like antifriction bearing element | US792309 | 1997-01-31 | US5758977A | 1998-06-02 | Wolfgang Bickle; Thomas Storch |
| In order to improve a bush-like antifriction bearing element for mounting a shaft, a pivot or other revolving component so that penetration of dirt into the bearing as well as out of the bearing, the antifriction bearing element is made pot-shaped so that the end of the antifriction bearing element remote from the end for insertion of the shaft, the pivot or the like, is defined by a bottom portion. | ||||||
| 71 | Method for producing a metal tip | US213013 | 1994-03-14 | US5502994A | 1996-04-02 | Akio Katoh; Kazuo Hamada |
| A cold forging apparatus for producing a metal tip for use, for example, in an electrode of a spark plug includes an intermediate die for receiving a metal blank, an upper die having a punch for forming a recess in the metal blank, and a lower die movable in a lateral direction. A press member is mounted on the lower die, and is retracted when a projection, extruded from the metal tip by the punch, is brought into pressing engagement with the press member. The punch is driven into the metal blank to form a recess and the projection respectively on upper and lower surfaces of the metal blank, and subsequently in a hydrostatic condition, the lower die is moved laterally to remove the projection from the metal blank. | ||||||

| A pierced metal blank having an annular cross-section with one end closed and the other end open for use in the manufacture of seamless tubes has a bore with portions of different diameters, the portion of larger diameter, which is adjacent the open end of the blank has a wall thickness which is less than that of the portion of smaller diameter which is adjacent the closed end of the blank. Preferably there is a conical transition between the two portions of different diameters. The blank is preferably made from a metal billet of square cross-section in a substantially cylindrical piercing mould by piercing the billet within the mould by means of a stepped mandrel which presses the material of the square billet outwards into contact with the cylindrical wall of the mould. | ||||||
