PROBLEM TO BE SOLVED: To provide a press working device of which a size is miniaturized and a cost is reduced.SOLUTION: A press working device 200 comprises a base 201 and a ram 202, a first driving means 205 for driving vertical movement of the ram 202, a guide member 207 for guiding the vertical movement of the ram 202, an upper die 200b fixed to the ram 202, a lower die 200a which is so attached to the base 201 as to be vertically movable, a second driving means 206 for vertically moving the lower die 200a with respect to the base 201, and a lock mechanism 230 which can connect the base 201 and the ram 202 to each other. In the state such that the base 201 and the ram 202 are connected to each other by the lock mechanism 230 thereby limiting lifting of the ram 202, the lower die 200a is lifted by the second driving means 206 and press working of a work-piece is carried out. |
