| 126 | Method for forming a lightweight flanged axle shaft | US811452 | 1991-12-19 | US5205464A | 1993-04-27 | Joseph 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 is separately forged out of metal with a disk-like flange and central cup-shaped hub whose free edge is of approximately the same 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 and to butt the adjacent faces to fuse them together upon discontinuance of the rotation. This produces a long, hollow, thin wall, lightweight shaft having one end closed by the flange extending laterally thereof. The flange hub and shaft end are integrated to form a one piece unit. The opposite end of the shaft is configured, such as with spline teeth, for fastening one end of the shaft to a drive or driven member while the flange at the opposite end of the shaft is secured to the opposite drive or driven member. | ||||||
| 127 | Method of producing a core for a fuel injector | US288217 | 1988-12-22 | US4932251A | 1990-06-12 | Setsuo Okada; Akashi Yamazaki |
| A bar-like workpiece is axially compressed to form a flange at the intermediate portion thereof. Then, the workpiece with the flange is held by dies and its one axial end surface is received by a receiver die. The receiver die has a recess formed at the central portion of its end surface for accommodating a slug flowing from the workpiece. The end surface of the receiver die around the recess forms a surface to receive the workpiece. From the side opposite to the receiver die a punch is continuously pressed into the workpiece beyond the flange position to form a sleeve insertion hole. Next, a residual material left at the bottom of the sleeve insertion hole is punched out by another punch, completing the fuel injector core. | ||||||
| 128 | Forging method for a hollow article | US364381 | 1989-06-09 | US4918969A | 1990-04-24 | Hirosato Takeuchi; Yutaka Tanaka; Osahiko Miyazaki; Noboru Saito; Haruo Kubo; Naoyuki Kotake; Makoto Nagumo |
| A forging method comprises the following four steps: a first step of disposing a columnar material into a first die and extruding one end portion of the material with a first punch in a direction opposite to the advancing direction of the first punch, a second step of deepending a first blind hole in a second stepped die with a cavity having large and small internal diameter portions, and extruding the other end portion of the material into the inside of the small internal diameter portion of the cavity with a second punch which has been previously extended thereinto, a third step of fitting the first and second blind holes to third punches while exposing the small outer diameter portion from a third die and pressurizing, by means of a sleeve, only an end face portion of the small outer diameter portion formed with the second blind hole to expand the small outer diameter portion of the material toward an outer periphery, and a fourth step of punching out a blind portion of the material. | ||||||
| 129 | Method of making a male resistance welding electrode | US351056 | 1982-02-22 | US4423617A | 1984-01-03 | Russell A. Nippert |
| A method of making a male resistance welding electrode includes a forward extrusion step in which the shank portion of the electrode is partially formed by extruding a cut-off billet of dispersion strengthened copper over a pin in a first die. Subsequently, the preform billet produced in the first die is inserted into a second die which defines a tapered shank cavity region around a central pin and a larger cavity region from which the head portion of the electrode is ultimately formed. The shank portion of the electrode is formed and the head portion worked substantially by the application of pressure to the preform billet by a first forming member. Final forming occurs when a second forming member applies pressure to the head of the electrode while the electrode remains in the second die. If desired, a small nose portion may be formed on the tip of the electrode by the second forming member and subsequently removed in a machining or cutting operation, eliminating surface irregularities in the electrode head portion surface. | ||||||
| 130 | Method of forming spark plug bodies | US241145 | 1981-03-06 | US4352283A | 1982-10-05 | Robert J. Bailey |
| A method of manufacturing a hollow spark plug body having a cylindrical central portion (28), a first end portion (10) of smaller circular radial cross-section and a second end portion of non-circular radial cross-section, e.g. hexagonal, and of smaller maximum diameter than the central portion by cold extruding the both end portions. The second end portion is extruded in two stages, the first involving the formation of a recess in one end of a cylindrical blank, the second involving extrusion the blank between a die (19) and a mandrel (21) which moves with the blank during extrusion. | ||||||
| 131 | Method of manufacturing an extruded steel component | US687209 | 1976-05-17 | US4068518A | 1978-01-17 | Ian Anthony Dockerill |
| A method of manufacturing an extruded steel component for use in a roller clutch assembly comprises initially providing a steel preform which defines a hollow shank part of the required component and which includes a hollow head portion tapering inwardly to the shank part, the external diameter of the head portion being substantially equal to the external diameter of a hollow head part of the required component, but the bore in the head portion having a diameter less than that required for the head part. Then with the preform positioned in a die cavity of the shape of the required component, an extrusion operation is performed on the head portion of the preform using a punch including inner and outer, relatively movable punch members, the inner punch member defining the shape of the bore required in the head part of the component. During the extrusion operation, the inner punch member is moved relative to the outer punch member and the die cavity so as to enter the head portion and produce the bore required in the head part of the component and a cam surface on the wall of the bore in the head part. The outer punch member defines the shape of the free end of the head part of the required component, and during the extrusion operation, is urged to apply a predetermined load to the head portion of the preform so as to restrict the flow of material extruded from the preform by the inner punch member, the material thereby being constrained to fill the region of the die cavity defining the head part of the component. | ||||||
| 132 | Method of manufacturing a steel component having a head part and a hollow shank part | US33894673 | 1973-03-07 | US3835686A | 1974-09-17 | LAWSON R; JABLONSKI Z |
| To manufacture a steel component having a head part and a hollow shank part, a steel slug is positioned in a die cavity having a narrow portion which defines the shape of the shank part of the required component. One end of the slug extends into the narrow portion of the die cavity and engages a first punch defining the shape of the bore in the hollow shank part, whereas the other end of the slug extends into a wide portion of the die cavity and engages a second punch. The first and second punches are then caused to undergo relative movement towards each other so that the first punch enters the one end of the slug. As the first punch enters the slug, it produces the required bore for the shank part of the component and the region of the slug surrounding the first punch moves relative thereto substantially without constraint. Also, in entering the slug, the first punch causes metal to flow towards the other end of the slug and into the wide portion of the die cavity, which is so dimensioned that the metal is not constrained to conform to the shape of the wide portion of the die cavity.
