    摘要： A process for producing an elongate semifinished product (30) having at least two differently profiled portions (37; 38) of predefined lengths uses the following steps. A continuously fed wire (31) is rolled by means of a rotating roller (39; 40). The circumference of the roller (39; 40) has a first segment (44) with a rolling profile (45; 46), which rolls a profile in first portions (37) of the wire (31), and a second segment (49) without a rolling profile, which is rotated with respect to the wire without making contact therewith. During rolling of the profile, a rotational speed of the roller (39; 40) is adapted in such a manner that a speed of the rolling profile (45; 46) is equal to the speed of the wire. During contact-free rotation, the rotational speed of the roller (39; 40) is adapted in such a manner that a length of the wire corresponding to a predefined length of the second portion (38) is guided past the roller without making contact therewith. A semifinished product (30) having the first portion (37) and the second portion (38) is separated from the reshaped wire.

    摘要： The distribution of load stresses on the engaged threads of a standard screw or nut is not even. Indeed, the first engaged threads bear a large majority of the load. Consequently, if the load is too great, the threads break and the function is not provided anymore by the screw or nut. The prior art describes threads having a depth or a pitch that vary substantially in order to induce self-tightening. The aim of the invention is to optimise the mechanical resistance and fatigue resistance of the screws via a better distribution of the load on the threads thereof and without inducing said self-tightening. It has been demonstrated that the control of the pitch variation, within a predetermined pitch range, makes it possible to control the distribution of the stresses on the threads. It is possible to determine a different variation corresponding to each load case encountered.

    摘要： The object of the present invention is to provide a bolt that effectively prevents gouging, seizure and racing between the bolt and nut without the aid of a guide boss and is effective when combined with the case nut.
    Said object can be attained by providing a bolt having a threaded shank portion (103) wherein a plural number of notched faces (104,105) slanting toward the end of said threaded shank portion (103) at an angle ranging from ±15° to ±80° toward the axis of said threaded shank portion (103), are formed at the beginning of the thread part (103A) of said threaded shank portion (103).

    摘要： A method and apparatus (12) for cold sizing a round workpiece (14) having round surfaces of cylindrical shapes that are coaxial about a central axis A of the workpiece and have different diameters. A support (54,55) rotatably mounts the workpiece (14) about its central axis A between a pair of die assemblies (24a, 24b) which are spaced from each other. Each die assembly (24a,24b) includes a plurality of dies (56,58,60,62) that are respectively aligned with the round surfaces (46,48,50,52) of the workpiece (14). Movement of the die assemblies in opposite directions as each other engages sizing surfaces (66,68,70,72) of the dies with the aligned round surfaces of the workpiece to pressure size the workpiece surfaces. In one embodiment of the sizing apparatus (12), the dies assemblies (24a, 24b) have elongated shapes and are moved rectilinearly in a parallel relationship to each other to perform the sizing. Another rotary embodiment of the sizing apparatus (12ʹ) includes rotary die assemblies (24aʹ,24bʹ) mounted by associated spindles (85) whose rotation likewise pressure sizes the round workpiece surfaces. Both embodiments of the sizing apparatus are disclosed as including forming projections for forming projections for forming projections such as splines (82) and/or a helical thread (84) on the sized surfaces of the workpiece.
