| 41 | Method of producing bushing | US10612160 | 2003-07-02 | US06842982B2 | 2005-01-18 | Yusuke Haga; Toru Okabe; Nobuaki Haga |
| By press-fitting a cylindrical blank into a die with one of a pair of punches, and at the same time press-fitting small diameter end portions and tapered portions of the pair of punches into both ends of the cylindrical blank while restraining both end surfaces of the blank with cylindrical members movable on the outsides of the punches, the external circumferential surface of the blank is finish molded to the required diameter by the internal circumferential surface of the die and, at the same time, tapered surfaces are formed on the inner circumferential surface in both ends of the blank. The process produces a bushing with its internal surfaces accurately coaxial, and with the external surface accurately formed to the required diameter. | ||||||
| 42 | Apparatus and method for restricting fluid flow in a planar manifold | US09873390 | 2001-06-05 | US06457236B1 | 2002-10-01 | Richard P. White; Michael Q. Thompson |
| The present invention refers to a novel apparatus and method to restrict pneumatic flow in a planar manifold. A forming tool of specific geometry is pressed into a planar manifold causing the pneumatic channel inside to collapse onto itself in a predictable and controllable way, therefore restricting the fluid flow in the pneumatic channel. The geometry of the forming tool is provided with angles and radii so that the planar manifold is not ripped during the pressing operation. Further, the geometry limits the deformed area so that distortion of adjacent pneumatic channels, and the potential for springing leaks between layers is minimized. In a preferred embodiment, the tooling also provides flow measurement while the forming tool is pressed into the planar manifold at a specific orientation. | ||||||
| 43 | Radial extrusion process combined with inside tune ironing | US937265 | 1997-09-15 | US5765425A | 1998-06-16 | Janez Pipan |
| A subject of the invention is the radial extrusion process combined with inside tube ironing, which is in essence a cold extrusion process and can be reckoned among bulk metal forming processes. It enables tube shaped metal semiproducts to be formed into different final shaped parts or parts that are intended for additional working, for example by machining. The process is grounded on insertion of a tube, which may be on one end previously expanded, into a proper shaped die, where on one side there is a punch which is retained with a determined force and inside which lies a free movable mandrel, while from the other side in working stroke the counter-punch extrude the difference of tube volume which results from ironing of the tube, in the direction of counter-punch travel so, that the material fills up the starting clearance between the mandrel and the tube, the space between the tube and the punch and arbitrary shaped space in the punch or in the die. | ||||||
| 44 | Apparatus having shaping jaws for manufacturing bodies of spindle-type shapes | US299586 | 1981-09-04 | US4379397A | 1983-04-12 | Oldrich Langr |
| Apparatus for making a spindle-type body with at least one eccentric zone from a semi-product of circular cross-section by gradually radially displacing the eccentric zone of the semi-product to bring its eccentricity from zero to the desired value. The apparatus includes a multi-part die with shaping jaws providing a semi-product shaping passage therein, the semi-product being thrust axially into the die while the semi-product and the die rotate relatively to each other. | ||||||
| 45 | Axle spindle forming method | US773456 | 1977-03-02 | US4100781A | 1978-07-18 | Joseph H. Zawacki; John P. Dutton |
| Apparatus and a method disclosed for forming an axle spindle from a hollow axle blank incorporate a hollow punch having a metallic body with an inner work surface defining a work opening and a mandrel fixed within the work opening projecting toward an open end thereof from a closed end of the opening. During forming, the punch is moved relative to the axle blank in the direction of the mandrel projects so that the mandrel is received within the hollow axle blank as the work surface of the punch body forms the blank about the mandrel to provide a spindle. Preferably, several punches of this type are utilized to complete the spindle forming process on the axle blank. Each punch preferably has an elongated annular shape with a round inner work surface and a round outer surface on the mandrel so that the formed spindle is of a round shape. One of the punches which causes outward material movement has an undercut on its mandrel to facilitate punch withdrawal. The forming is best performed by a hot forging operation on a heated axle blank end and the hollow punch body has a sufficient length so it extends past the heated portion of the blank end before deformation begins. A pair of cooperable gripper dies include gripping portions for locating the axle blank during the forging and define an elongated opening with a round cross section for slidably receiving and guiding the punch body during the movement that forges the axle spindle. A lubrication passage in the punch supplies a lubricant between the punch body work surface and the mandrel. | ||||||

| 47 | Internal extrusion device and method of internal forming | US43779974 | 1974-01-30 | US3884066A | 1975-05-20 | WILLMON LD |
| The formation of non-circular bores in metal parts achieved by drilling a circular bore and ramming a mandrel (or punch) of the desired cross sectional configuration through the circular bore to cause a displacement of metal, primarily radial in character to complete the bore. The invention is particularly useful in working on steel, and the mandrel for this purpose should be of very hard, preferably tungsten carbide steel, whereby a fine micro smooth finish in the bore is produced. The pieces are worked on cold and may be heat treated thereafter for hardening. A typical example of the finished bore is one of hexagon shape.

| A round tubular work-piece of substantially uniform diameter and wall-thickness is forged from within, by a particularly shaped spud or mandrel, to obtain a nozzle or connector element having therewithin a substantially uniform cross-sectional area which changes in shape from round to oblong whereby it may uniformly supply fluid to a larger number of tubes or the like which are arranged in spaced parallelism with respect to each other.
