| 133 | Method and tool for forming a tapered hole in a cylindrical work by punching extruding | US809682 | 1997-06-25 | US5816093A | 1998-10-06 | Hirosato Takeuchi; Shigeru Yasuda; Haruo Kubo |
| This invention provides a forming method capable of forming tapered through holes at once with a single pressing operation. A hole is formed in a work with a piercing punch 1 mounted on a press by using a small-diameter punching portion 1a formed on the distal end of the punch 1. A hole 11 formed at this time has a section with an open lower end portion by pressing. By using this hole 11 as a guide, a tapering portion 1b having a diameter slightly larger than the diameter of this hole and a tapered surface T forms a tapered surface on the inner surface of the hole 11 in accordance with plastic working. A "burr 3a" is formed on the edge of the hole 11 by this plastic working. Formation of this "burr 3a" is prevented with a pressure portion 1c formed on the piercing punch 1. When the above process is performed in a single pressing operation, a plurality of tapered through holes can be formed easily. | ||||||

| A method of fabricating a tube having enlarged ends and made of material which can be strengthened by cold working comprises fabricating a pre-form having the overall configuration of the tube but with increased outside diameters and a decreased length. The pre-formed tube is cold forged or cold rolled over its entire length to reduce its outside diameter while maintaining its inside diameter substantially fixed. This elongates the tube and reduces its cross-sectional area. Cold working is continued until the final desired dimensions for the tube are reached. This produces a strengthening effect by cold working over the entire length of the tube. | ||||||
| 138 | Axle spindle forming apparatus | US883776 | 1978-03-06 | US4208900A | 1980-06-24 | 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 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. | ||||||
| 139 | Method of cold forming | US864544 | 1977-12-27 | US4166373A | 1979-09-04 | Frederick W. Braun |
| The invention relates to the cold extrusion of a part having a polygonal interior and a cylindrical exterior. Instead of the usual process of forcing a polygonal punch into a billet in a single extrusion step, the new method employs a plurality of extrusion steps, first forming a lobed preparatory blank and then in a second extrusion step providing a punch and die combination whereby the external lobes of the intermediate part are forced radially inwardly. In the second extrusion step a polygonal punch is used to provide the proper polygonal interior surface. A cooperating die is provided with an upper lobed cavity for receiving the lobed preparatory blank and this die is oriented with respect to the polygonal punch so that the interior lobes of the die are exactly opposite the flats of the polygonal punch. Below the upper lobed cavity of the die is a cylindrical cavity of smaller diameter and between the two is a conical surface which directs the metal of the lobes inwardly into the die cavity opposite the flats of the polygon. The preferred polygon is a hexagon. | ||||||
