摘要： A rolled steel bar for hot forging consisting, by mass percent, of C: 0.25-0.50%, Si: 0.40-1.0%, Mn: 1.0-1.6%, S: 0.005-0.035%, Al: 0.005-0.050%, V: 0.10-0.30%, and N: 0.005-0.030%, and the balance of Fe and impurities, i.e., P: 0.035% or less and O: 0.0030% or less, wherein Fn1=C+Si/10+Mn/5+5Cr/22+1.65V−5S/7 is 0.90 to 1.20. The predicted maximum width of nonmetallic inclusions at the time when a cumulative distribution function obtained by extreme value statistical processing by taking the width of nonmetallic inclusion in an R1/2 part of a longitudinal cross section of the steel bar as W (μm) is 99.99% is 100 μm or narrower. The number density of sulfides each having a circle-equivalent diameter of 0.3 to 1.0 μm observed per unit area of the R1/2 part of a transverse cross section of the steel bar is 500 pieces/mm2 or higher.

摘要： A forging apparatus and method is disclosed in which an extrusion punch is held between an upper press and a lower press and propelled towards a billet by a ram to form an extruded shaped component. The extrusion punch has a striking face in which a recess is formed. During the extrusion process, material from the billet enters the recess so as to lock the extrusion punch and the shaped component together. Accordingly the shaped component is not lifted up with the upper press when it is separated from the lower press and so the position of the shaped component after the forging extrusion operation is known accurately and reliably.

摘要： A drive plate having a plate portion and a ring portion is shaped integrally by pressing using dies. The ring gear portion has inner recessed portions positioned on the inner side of a plurality of outer teeth. The inner peripheral surface of each of the inner recessed portions includes an inner bottom surface having a pair of curved corner surfaces, a pair of first side surfaces inclined so as to become closer to each other as the first side surfaces extend from the opening end of the inner recessed portion toward the inner bottom surface, and a pair of second side surfaces formed in a band shape between the corner surfaces and the first side surfaces. The degree of inclination of the second side surfaces with respect to a center line is smaller than the degree of inclination of the first side surfaces with respect to the center line.

摘要： A method for producing a camshaft module and a camshaft module are provided. The camshaft module includes a camshaft and a bearing frame having bearing devices with cut-outs. The camshaft includes a shaft and cams having cut-outs. The shaft has at least two different outside diameters. At least some of the cams and/or some of the bearing devices have cut-outs of differing diameters. The bearing frame is supported during shaft insertion to be movable along a movement axis during production of the camshaft module and to be substantially rigid along an insertion direction of the shaft. The shaft is inserted into the bearing frame in the insertion direction in such a way that interference fit is obtained in each case at least between the shaft and at least some of the cams. A predefined target distance between two elements such as a gear located outside of the bearing frame and a cam or bearing device located inside of the bearing frame adjacent to the element outside of the bearing frame may be obtained by partially inserting the shaft, determining a distance between the two elements, and applying an insertion force to the shaft based on the determined distance to advance the shaft to result in setting the distance between the two elements to the target distance.

摘要： A hybrid induction welded piston including an upper piston part welded to a lower piston part is provided. The piston is produced by induction heating the upper piston part and the lower piston part, and bringing the parts together to a part growth compensated position. The method then includes rotating the upper piston part 17 to 34 degrees clockwise and then 17 to 34 degrees counterclockwise. In addition to controlling the axial position and degree of rotation, the force applied to the piston parts is controlled so that preferably no flash is formed in a narrow cooling chamber of the piston. During the rotating steps, the pressure gradually increases to a maximum level which occurs while the upper piston part is rotating in the second direction. The piston includes a homogenous metallurgical bond across the weld and no indentation on the outer surface at the weld prior to machining.

摘要： A motor rotor and a method for manufacturing a motor rotor, enabling crimping of the resolver rotor at low cost with less influence on the detection accuracy. A motor rotor includes a resolver rotor and a rotor shaft to which the resolver rotor is affixed by crimping. The rotor shaft includes a first stepped section with which a crimping punch makes contact to deform the first stepped section, a second stepped section with which an end surface of the resolver rotor makes contact, and a cutout groove formed in a surface which is located near the first stepped section and with which an inner peripheral hole section of the resolver rotor makes contact. In the crimping operation, the first stepped section of the rotor shaft is bent within the cutout groove to form a crimping protrusion which presses the end surface of the resolver rotor.
