摘要： A preform (W') for a connecting rod (W) of an engine is manufactured with a good productivity. The preform (W') has a large-end mass portion (W'a) which corresponds to a large-end portion (Wa) of the connecting rod (W), a small-end mass portion (W'b) which corresponds to a small-end portion (Wb) thereof, and a shaft portion (W'c) which corresponds to a rod portion (Wc) thereof. There is manufactured a preform blank which has a shaft-shaped portion which is formed by extrusion. This shaft-shaped portion is made up of the shaft portion (W'c) and an extended portion (W'd) which extends axially forward from the shaft portion (W'c). The small-end mass portion (W'b) is formed by squeezing the extended portion (W'd) in the axial direction in a plurality of times starting with a portion near the shaft portion (W'c).

摘要： At the time of closing a die mold, an upper die (18) is rotated with respect to screws (44a-44d) while being brought into contact with a lower die (14) by means of drive gears (42a-42d) and a driven gear (40), wherein a closing force is applied to the material (W) by plate springs (60). Subsequently, at the time of opening the die, under an opposite operation, the upper die (18) is opened while being simultaneously rotated with respect to the screws (44a-44d) which are supported by coil springs (54a-54d), whereby a spiral bevel gear (72) is released from the mold. Accordingly, at the time of die closing, the closing force is kept stable, whereas when the die is opened, imposition of a large force to the gear teeth is prevented, so that bevel gears (72) of high quality and high yield rate can be produced.

摘要： At the time of die clamping, an upper die (18) abuts against a lower die (14) while being rotated by drive gears (42a to 42d) and a driven gear (40) with respect to screws (44a to 44d), and a belleville spring (60) applies a die clamping force on a stock (W). Subsequently, at the time of die opening, the upper die (18) is rotated with respect to the screws (44a to 44d) supported by coil spring (54a to 54d) simultaneously with the die opening in an action opposite to the above, so that the die is released from a spiral bevel type gear (72).
摘要翻译：在关闭模具时，通过驱动齿轮（42a-42d）与上模（14）接触，上模（18）相对于螺钉（44a-44d）旋转，并且从动齿轮（40），其中通过板簧（60）向所述材料（W）施加闭合力。随后，在打开模具时，在相反的操作下，上模18被打开，同时相对于由螺旋弹簧（54a-54d）支撑的螺钉（44a-44d）同时旋转，由此螺旋伞齿轮（72）从模具中释放出来。因此，在关闭时，闭合力保持稳定，而当打开模具时，可以防止对齿轮齿施加大的力，使得高质量和高产率的锥齿轮（72）可以生产。

摘要： PROBLEM TO BE SOLVED: To provide a forging method and a double-acting die apparatus for forging by which a locking force with a first die is not lowered when starting a second-step forging. SOLUTION: At the second-step forging time, first punches 2L, 2R are pressed in a work W under the state of closing a hydraulic chamber 32 in a second die holder 6 and a work compressed force with the punches 2L, 2R, is received with the hydraulic chamber 32 through second punches 5L, 5R and a piston 30. At the step when the compressed force to the work W with the first punches 2L, 2R reaches a predetermined value, the oil in the hydraulic chamber 32 is released and the second punches 5L, 5R are deeply inserted into a second die 4 to punch out the work W.
