摘要： PROBLEM TO BE SOLVED: To provide a production method with which a nut having strength equivalent to that of the A2-70 standards specified in JIS can be produced. SOLUTION: When a high strength nut made of an austenitic stainless steel is produced by hot forging, the stock of the austenitic stainless steel is worked into a nut blank by hot forging, the nut blank is subjected to working of a female screw with a diameter smaller by 200 to 400 μm than the effective size of the nut blank on it, and thereafter, the surface of a screw thread is plastically deformed by cold thread rolling tap so as to work the female screw with an effective diameter.

摘要： PROBLEM TO BE SOLVED: To repeatedly form parts having larger cross-sections than raw material and a round penetrated hole at the central part from a long linear material without generating any scrap.
SOLUTION: In the first pressure forming process S1, the tip part of a long linear material A is protruded by a predetermined length from the penetrated hole 3a of a die 3 to the front side, and while the state of protrusion of the tip part is held, a punch 7 having a center pin 7 which is identical to the material A in a cross section is advanced to the die side and also the center pin 7 is advanced near the die side from the inner side of a center hole of a shaping recessed part 4a, so that the protruded tip part of the material A is pushed back to the die side and a hexagonal blank B is integrally formed at the tip part. Thereafter, the hexagonal blank B and the material A are punched out by releasing the holding of the material A and advancing the center pin 7. In the second pressure forming process, a hexagonal nut N is formed by modifying and heading the shape of the hexagonal penetrated hole B1 of the hexagonal blank B to a requested shape of a round penetrated hole N1.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a nut, by which the nut can be manufactured from a metallic material having a thickness thinner than the length of a female screw, and can suppress an unnecessary waste of a material. SOLUTION: The method for manufacturing the nut comprises thickness increasing steps (a) to (c) for increasing the thickness of a metallic material 10 around a through-hole 11 formed therein by enlarging the diameter of the through-hole 11 by press work, and a female screw forming step for forming a female screw on the inside peripheral surface of the through-hole 11 enlarged in the thickness increasing steps. In the thickness increasing steps, the outside peripheral surface of the metallic material 10 is bound by means of a press die so as not to deform the outside peripheral shape of the metallic material 10. Further, in the thickness increasing steps, the portion around the through-hole 11 in one surface (a punch side surface 13) of the metallic material 10 is heaved by press work, and the other surface (a die side surface 12) of the metallic material 10 is restrained by means of the press die so as to become a flat surface.

摘要： PURPOSE:To facilitate working and to improve reinforcing effect by press-fitting an upper and a lower die into the tapered hole of a reinforcing case and making the cone angle of the outer circumferential tapered surface of the lower die smaller than the cone angle of the corresponding surface of the upper die. CONSTITUTION:The dies are so constituted that the upper die 2 and the lower die 3 in which cavities 22 are formed are press-fitted into the tapered holes 11, 12 of the reinforcing case 1, and that a tightening screw 5 is screwed onto the reinforcing case 1. The cone angle of the outer circumferential tapered surface 36 of the lower die is smaller than that of the corresponding surface 21 of the upper die 2. The tapered hole of the reinforcing case 1 is constituted of a first tapered hole 11 corresponding to the tapered surface 21 of the upper die 2 and a second tapered hole 12 which is on the same axis as the first tapered hole and corresponding to the tapered surface 36 of the lower die 3. When the same pressurizing force is applied on the lower and the upper dies, a force for giving an elastic deformation to the reinforcing case 1 and the quantity of elastic deformation for the reduced diameter of the die itself are larger in the lower die having a smaller cone angle of the outer circumferential tapered surface than in the upper die. Consequently, the reinforcing effect is enhanced by the reinforcing case.
