PROBLEM TO BE SOLVED: To provide a press working apparatus capable of working a workpiece with high accuracy at a fast working speed and with a long metal mold life.SOLUTION: In a metal mold of a press working apparatus 1, a workpiece is placed between a lower die 30 and an upper die 10, the upper die 10 is pressed toward the lower die 30 in a first direction, and the workpiece is worked. The upper die 10 includes: an action end 13 which is brought into contact with the workpiece so as to perform mold push; a vibration end 14 which is provided on an opposite side of the action end 13 along the first direction and to which vibration is given; a pair of holding sections 15 which are separated in a second direction orthogonal to the first direction and are provided between the action end 13 and the vibration end 14, fix the upper die 10 and transmit driving force in the first direction to the upper die 10; a hole which passes through the upper die 10 in a third direction orthogonal to each of the first direction and the second direction and is provided between the pair of holding sections 15.SELECTED DRAWING: Figure 1 |
