摘要： A method of producing a press-formed product includes a steel plate heating step, a hot forging step and a hot stamping step. In the steel plate heating step, a steel plate is heated to 950° C. or more. In the hot forging step, the heated steel plate is forged to form a varying-thickness steel plate. In the hot stamping step, the heated varying-thickness steel plate is subjected to press-working by a press tooling to form a press-formed product, and the press-formed product that is formed is cooled inside the press tooling. Thus, a press-formed product that has high strength and for which a reduction in weight is possible can be produced.

摘要： An apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool are provided. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample or charge of metallic glass alloy to a predetermined “process temperature” between the glass transition temperature of the amorphous material and the equilibrium melting point of the alloy in a time scale of several milliseconds or less. Once the sample is uniformly heated such that the entire sample block has a sufficiently low process viscosity it may be shaped into high quality amorphous bulk articles via any number of techniques including, for example, injection molding, dynamic forging, stamp forging, and blow molding in a time frame of less than 1 second.

摘要： A hollow stepped article is formed from a solid blank to reduce the material cost, and cracking is prevented in a stepped portion of large diameter when a portion of the blank is deformed by its radial expansion. A hollow stepped shaft is formed by holding an upper and a lower part axially of a solid rod-like blank with an upper and a lower die, respectively, which have a stepped recess of large diameter in a region where they are opposed to each other; compressing the blank from both its axially opposite sides with an upper and a lower punch each of which is smaller in diameter than the blank, thereby extruding the blank so that an axial hollow is formed therein about its axis in each of its upper and lower parts and that a portion of the blank opposed to the stepped recess of large diameter expands in diameter and deforms into that recess while leaving a solid plug-like portion between the punches; and thereafter further compressively moving one of the punches to shear the solid plug-like portion and force it out of the blank, whereby the blank is formed with a stepped portion of large diameter by radially expanding deformation in a region intermediate between its opposed ends or at one of these ends and with a continuous axial hollow about its axis.

摘要： A forging system comprises a furnace with heating elements to heat a billet which is pressed against a die at a controlled rate and pressure. A signal processor controls the temperature, pressure and rate as a function of parameters entered on a keyboard the signal processor displays those parameters along with real time values of temperature pressure and distance for the billet in a graphical interface that includes a model of the billet and furnace with elements that change size during the forging processor. Forging pressure is displayed, in this interface, on an incremented bar.

摘要： An electrical upsetting method for upsetting a cylindrical metal material, which is durable against wear and tear due to high temperature as well as vigorous friction under heavy pressure during the upsetting work, wherein a space gap is provided between the outer peripheral surface of the workpiece and the inner peripheral surface of the shaping die to prevent the die from direct heat from the workpiece generated by electric conduction across the electrodes, or wherein a space gap is provided between the outer peripheral surface of the anvil electrode and the inner peripheral surface of the shaping die, and an inert gas is filled in the space gap to protect the die from oxidation due to its exposure to the external atmosphere, or air, as well as to maintain the die in a cooled condition by the inert gas.The present invention also proposes an improved electrical upsetting device provided with the inert gas feeding device which supplies such inert gas through the communicating grooves into the space gap defined between the anvil electrode and the shaping die to prevent the die from wear and tear due to its oxidation through exposure to the external atmosphere, thereby securing long service life of the shaping die.

摘要： First a metallic pipe is tapered, so that it is substantially closed at its end, and so that its cross-section is reduced. Then it is pressed hard against a mold electrode, and a large electric current is passed through it to the mold electrode, so that the end softens, but does not melt, and by the pressing (which may be of the order of 2.5 tons weight) the end is formed into a lump, with no trace remaining of the hole through the pipe within the lump. In certain embodiments, the mold electrode may be formed with a notch, and/or a depression, and may be inclined at an oblique angle to the axis of the pipe, and may be moved sideways or at an oblique angle to the axis of the pipe as the current is passed and the lump formed.
