    摘要： A method of producing a cam lobe piece (1) of an assembled camshaft in a valve operating system for an internal combustion engine. The method comprises (a) forming a profile of the cam lobe piece (1) by upsetting a material (W) under forging to obtain an intermediately formed body (W1); (b) piercing a central portion of the intermediately formed body (W1) to form a shaft bore (2); and (c) ironing an inner peripheral surface of the pierced intermediately formed body (W1) to form unevenness at the inner peripheral surface, all accomplished by cold working. The material at the forming the profile of the cam lobe piece (1) has a first section (5a) located on a side of a cam nose of the cam lobe piece (1), and a second section (5b) located longitudinally opposite to the first section. The material has a thickness which gradually increases in a direction from the second (5b) section to the first section (5a).

    摘要： A process is disclosed for manufacturing flat bearing shells. A strip of material (2) is cut into bearing shell sections (26), these sections are bent into a semicircular shape, and the outer and inner sides (88, 58), as well as the parting surfaces (52) of the thus obtained bearing shells are calibrated. An oil groove (14) is shaped on the inner side (58) from parting surface (52) to parting surface (52). For the oil groove to be more easily shaped with a less complex milling tool, the oil groove (14) is continuously shaped, in particular milled, broached or sandblasted in the strip of material (2) before the strip of material is cut into bearing shell sections (26), and a cutting die (6) which matches the cross-section profile of the strip of material (2) after the oil groove (14) is milled is used to cut the strip of material into bearing shell sections (26).

    摘要： A hole punching method capable of executing hole punching with high material yield at a low load and preventing occurrence of underfill is provided. The hole punching method includes a step of expanding a hole punching scheduled portion 2 of a raw material 1 disposed in a cavity 12 of a closed die 11 by pressing the hole punching scheduled portion 2 from opposite sides thereof across the hole punching scheduled portion 2 with a pair of large diameter punch and small diameter punch 13 and 15 different in diameter and arranged to as to face each other so that unfilled portions remain in the cavity, a step of penetrating the small diameter punch 13 into the hole punching scheduled portion 2 of the raw material 1 while releasing or after releasing pressurization by the large diameter punch 15 to the hole opening scheduled portion 2, and a step of penetrating the large diameter punch 15 into the hole punching scheduled portion 2 of the raw material 1 while pulling out or after pulling out the small diameter punch 13 penetrated in the hole punching scheduled portion 2 of the raw material 1 from the hole punching scheduled portion 2 of the raw material 1.

    摘要： An object is to provide a fine forging method for forming partitions of recesses precisely and forming recess shapes for pressure generation chambers etc. with high accuracy as well as a liquid ejection head etc. that is produced by using the fine forming method. A fine forging method for forming groove-shaped recesses 33 that are arranged at a prescribed pitch. After groove-shaped recesses 33 are formed tentatively in a material plate 55 by a first punch 51a in which tentative forming punches 51b are arranged, finish forming is performed on the tentatively formed groove-shaped recesses 33 by using a second punch 51c in which finish forming punches 51d are arranged. An end portion of a projection strip 53c or 53d is formed with slant faces 63 and 64 or a slant face 65, whereby an end portion of each groove-shaped recess 33 is formed precisely. A liquid ejection head 1 produced by the above method exhibits stable liquid ejection characteristics and its manufacturing cost can be reduced by virtue of simplified working of forging.
