  • Patent number: 10456828
    Abstract: A forged crankshaft production method includes a first preforming step, a second preforming step, and a final preforming step. The first pair of dies includes web processing parts to come into contact with portions to be formed into arms and portions to be formed into weights integrated with the arms. Each of the web processing parts includes an arm processing part and a weight processing part. The arm processing part and the weight processing part form a recessed portion, and the width of the open side of the weight processing part becomes greater with increasing distance from the bottom of the recessed portion. Accordingly, in the blank, volume can be distributed between a portion to be formed into an arm and a portion to be formed into a weight integrated with the arm, and the material yield rate can be improved.

  • Patent number: 10391546
    Abstract: A forged crankshaft production method includes a first preforming step, a second preforming step, and a final preforming step. In the first preforming step, sectional areas of portions to be formed into pins and sectional areas of portions to be formed into journals are decreased, whereby flat portions are formed, and the portion to be formed into the pin located at a second position is decentered. In the second preforming step, a portion to be formed into the pin located at a first position is decentered, and a portion to be formed into the pin located at a third position is decentered to a side opposite to the portion to be formed into the pin located at the first position. In a blank obtained thereby, portions to be formed into pins have been reduced and decentered, and the material yield rate can be improved.

  • Publication number: 20190224741
    Abstract: Provided is a production method, including a first preforming process, a second preforming process, a final preforming process, and a finish forging process. In the first preforming process, regions to be a pin and a journal are pressed respectively from a direction perpendicular to an axial direction of the billet, thus reducing cross sectional areas of each region and forming a plurality of flat parts. In the second preforming process, the first preform is pressed in the pressing direction, which is a direction perpendicular to decentering direction of a region to be a second pin. In the final preforming process, the second preform is pressed from a direction perpendicular to an axial direction of the second preform, and further a region to be a counterweight and a region to be a crank arm integrally including a counterweight are pressed in the axial direction of the second preform.

  • Patent number: 9404406
    Abstract: A catalyst for use in a process for purifying exhaust gas from a gasoline engine of the fuel-direct-injection type that varies, in response to changes in the air-fuel ratio, between a first exhaust-gas state featured by an air-fuel ratio in the vicinity of the stoichiometrical air-fuel ratio, and a second exhaust-gas state that forms a more oxidizing, low-temperature atmosphere and that is featured by an air-fuel ratio greater than the stoichiometrical air-fuel ratio, the catalyst being obtained by causing a noble metal and a rare-earth oxide and/or a transition metal to be carried by or to be mixed with a fire-resistant inorganic oxide.
