A method of forming a housing which includes roll forming a steel tube radially inwardly with a plurality of rollers each having a rolling axis parallel to the longitudinal axis of the tube, the rollers compressing the tube and forming reduced diameter portions and enlarged diameter portions. The method then includes cutting the tube perpendicular to the longitudinal axis generally midway through an enlarged diameter portion and a reduced diameter portion, forming a plurality of minor image preforms. Finally, the method includes cold working the preforms into the desired shape of the housing and increasing the strength of the steel at least 15% and forming a housing member having enlarged diameter open end and a reduced diameter open end. |

A ball screw is provided in which an outer circumferential formation is formed at a portion facing a ball circulating passage out of outer circumferential surface of a nut. The ball screw includes: a screw shaft having on its outer circumferential surface a screw groove; a nut having on its inner circumferential surface a screw groove facing the screw groove; a plurality of balls rollably loaded in a spiral ball rolling passage formed by both screw grooves; and a ball circulating passage to return the balls from a start point to an end point of the ball rolling passage for recirculation. The ball circulating passage is a concaved groove formed by concaving a groove on a part of the cylindrical inner circumferential surface of the nut by plastic working. Then, a flange is integrally provided at a portion facing the ball circulating passage and the screw groove. |

A method for processing a steel tube includes the following steps: a softening step, in which a tube-to-be-processed is heated so that material property of the tube-to-be-processed is softened; a cooling step, in which the heated tube-to-be-processed is cooled down to a normal temperature; a wall cutting step, in which the cooled tube-to-be-processed is subjected to cutting by lathing an end section thereof so as to reduce wall thickness of the tube-to-be-processed at the end section; and a shrinking step, in which the thickness reduced section of the wall lathed tube-to-be-processed is subjected to compression to have an inner bore thereof shrunk and thus reduced, whereby occupation of the inner bore of the shrunk tube-to-be-processed by the wall thickness of the tube-to-be-processed is reduced so as to obtain a possible maximum inside diameter of the inner bore and prevent the tube-to-be-processed from undesired deformation and breaking. |

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. |

A clutch drum made of a metallic plate having on its peripheral wall portion spline teeth for engaging with clutch plates is formed by pressing with a die which has formed tooth grooves on its periphery and tooth-shaped punches which are disposed around the die so as to move radially back and forth. The force of pressurizing the toothed punches against the tooth flank portions of the spline teeth is made smaller at an open end thereof than at an ordinary portion of the clutch drum such that the thickness of the flank portions of the spline teeth becomes thicker at the open end than at the ordinary portion. |

A shatterproof pressure vessel for storing pressurized gas used in a hybrid-type air bag inflator until the gas is expanded for inflating an air bag, is formed of a thin wall, metal tube made by extruding a metal ring axially through a constricted die orifice to provide an elongated tube. The extrusion generally aligns the metal grain structure into a generally elongated, axially oriented fiber-like configuration. End closures are secured to the opposite ends of the tube to form the sealed pressure vessel. One end closure is openable to receive an ejection from a solid propellant means which is actuated for heating and expanding the gas within the vessel. The opposite end closure is openable to release the expanding gas into a vehicle occupant restraining air bag for inflation of the bag. In the event that the gas pressure within the tube exceed the burst strength of the tube wall, the wall will split along its axial longitudinal direction to provide an opening for relieving the excess pressure, rather than shattering into fragments. |

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. |

Forming die for manufacturing screw workpieces of a tube semi-product, e.g. rotors of single-spindle pumps. The function cavity of the forming dies consists of a guide part, a forming part, and a calibrating part. The guide part of the function cavity is formed by the intersection of a cylindrical surface and a helix, the forming part is formed by the intersection of a conical surface and a helix, and the calibrating part is of the shape of the helix of the final product. A minimum length of the guide part of the function cavity is equal to the diameter of the cylindrical surface, but the minimum length of the forming part as well as the length of the calibrating part of the function cavity is equal to one lead of the helix. The ratio of the diameter of the cylindrical surface of the guide part to the diameter of the helix is at least 1.1:1. |

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. |
