摘要： For forming a tubular work into a shaped hollow product by using hydroforming process, a method and a device are described. In the method, female and male dies are prepared. The female die has a longitudinally extending cavity which has a polygonal cross section when receiving the male die. The tubular work is placed into the cavity of the female die. The interior of the tubular work is then fed with a hydraulic fluid, and the pressure of the fluid is increased to a given level. The given level is smaller than a critical level that causes a bulging of the tubular work. The male die is then pressed against the tubular work to deform the same while keeping the hydraulic fluid at the given level, thereby forming a shaped hollow product that has a polygonal cross section that conforms to that of the cavity. The pressing work is continued until a circumferential length of the shaped hollow product becomes shorter than that of the tubular work.

摘要： A nozzle to be used for hydrostatic forming, through which pressurized fluid is supplied into a tube located inside a die. The nozzle comprising a fitting section integrally connected to a base section and insertable into an end section of the tube so as to be fitted in the tube. The fitting section has an opening through which the pressurized fluid is ejected to be supplied into the tube. The fitting section has a generally rectangular cross-section in a place perpendicular to an axis of the nozzle.

摘要： A rotor to be used in combination with a wheel speed sensor forming part of an anti-lock brake system. The rotor comprises an annular axial central section formed of a magnetic material. First and second annular axial end sections are coaxial and integral with the central section. The first and second annular axial end sections are formed of the magnetic material and arranged such that the annular axial central section is located between the first and second annular axial end sections. A plurality of holes are formed in the annular axial central section. The holes are arranged at equal intervals in the peripheral direction of the annular axial central section. A plurality of first and second depressions are respectively formed in the first and second axial end sections. A pair of the first and each second depressions are respectively located opposite to each other and connected with each hole.

摘要： At a time of manufacturing a clutch drum formed in a cup shape, having a peripheral wall formed in a tooth profile, and having a circumferential groove for mounting a snap ring in a portion close to an open end of an inside projecting portion, in a stage of forming a peripheral wall of a base material formed in a cup shape into a predetermined tooth profile, after forming in such a manner that a minimum outer diameter of the open end portion of the inside projecting portion is larger than a maximum diameter of the circumferential groove for the snap ring, a cutting process is given to the open end portion of the inside projecting portion 3, so that the circumferential groove is formed. Accordingly, a tooth profile having an uneven amount necessary for transmitting a rotation is secured and no extending portion is produced in the open end portion of the inside projecting portion.
