    摘要: The object of the present invention is to prevent the encroaching and the seizure between the bolt and the female screw caused by an oblique screwing of the bolt into the female screw when the bolt and the female screw are fastened together. Another object of the present invention is to manufacture the bolt in a low cost, by using said bolt, the encroaching and the seizure between the bolt and the female screw caused by a oblique screwing of the bolt into the female screw are certainly prevented. Said objects may be attained by a bolt consisting of a column part and a polygonal pillar part extending from an end of said column part wherein a complete thread is formed on said column part and a screw blade continuing to said complete thread is formed on said polygonal pillar part.

    摘要: A fastener sorting apparatus is configured to mount on a fastener forming machine and to shunt bent workpieces through a wastegate of the fastener forming machine when the bent workpieces contact a detection ring. The detection ring is electrically-conductive and is coaxially aligned with a part gripper of the forming machine. The ring has an inner diameter slightly larger than an outer diameter of a series of workpieces to be sorted. Either the ring or the gripper are moved so that a workpiece held in the gripper passes through the ring. If the workpiece is bent beyond acceptable limits it will contact the ring, closing an electrical circuit. Closing of the circuit causes a workpiece diverter to shunt the workpieces through the wastegate.

    摘要: The process is carried out using a press tool which has a plurality of dies which are arranged around a longitudinal axis and are radially displaceable with respect to this axis. The radially inner surfaces of the dies correspond to segments of the conical thread to be pressed. During pressing of a conical thread in cylindrical workpiece, the dies are first drawn apart in the radial direction and the workpiece is then pushed between the dies, along a length which corresponds to only a few thread turns. The dies are then pressed toward one another in order to press into the workpiece a short conical thread in which only the first thread turn may be formed to its full depth. After the dies have been drawn apart, the workpiece is displaced between the dies through a further length which once again corresponds to only a few thread turns. When the dies are pressed toward one another again, the previously pressed thread turns are pressed deep into the workpiece and additional thread turns are formed. This process is repeated several times until the conical thread has been pressed to the predetermined total length.

    摘要: A male conical thread of an elongated steel structure, e.g. a steel rod or wire of the type employed as reinforcement in pre-stressed concrete, for use in engagement with a matching female conical thread provided in a fixing sleeve or other nut means is formed by first shaping an end portion of the wire or rod, e.g. by grinding or hammering, into a cone that tapers down towards the end of the rod or wire and has a generally truncated smooth outer surface; then, the cone's surface is deformed by cold-pressing such that the thread is formed. Further, a press-die appartus is disclosed for use in such cold-pressing, e.g. at a construction site where steel reinforcements are mounted.

    摘要: A method of making a screw for forming internal threads in a hole in a work formed from a blank having a shank portion and a frusto-conical shaft portion. Three flat portions extending parallel with the axis of the blank are formed on the shank. A length of the end portion of the frusto-conical shaft portion is left as right circular. A delta formed region is formed on the head end of each flat portion, and has a peripherally arcular convex surface and tapers to the flat portion. By thread rolling all but the shaft end portion, spoon-like recesses are formed at the crest of the threads passing on the flat portion to form inducing male threads. The depth of the spoon-like recesses sequentially decrease on the delta formed region to produce transient torque increasing characteristics.

    摘要: A drill and thread forming threaded fastener having a roll threaded shank constructed at one end for selective engagement with a driving tool, a forged drill point at the other end of the shank comprising a generally cylindrical section adjacent to said threaded shank and terminating in a generally paraboloidal tip section, a pair of diametrically opposed flutes occupying substantially entire diametrically opposed quadrants and having longitudinally extending generally planar surfaces located substantially in a diametric plane containing the axis of the fastener, the radially outer margins of which form cutting edges. The flutes form diametrically opposed quadrants the surfaces of which for the generally cylindrical section of the drill point are partial sectors or approximately one-half segments of cylinders having axes offset from the aforesaid diametric plane containing the axis of the fastener in the direction towards the other partial sector to provide clearance for the cutting edges along the generally cylindrical section of the drill point. In the generally paraboloidal section of the drill point, the flutes form partial sectors of paraboloids, the axes of which coincide with the axes of the aforesaid cylinders which form the radially outer surfaces of the generally cylindrical section and the bases of which coincide with the ends of the aforementioned cylinders adjacent thereto, thus providing clearance for the cutting edges along the generally paraboloidal section of the drill point.
