<p>In the press working machine, a first working plate (10) is downwardly moved by a rod (9) of an air cylinder (8). At this time, the lower end of a lock pin (11a) is in contact with a horizontal plane (16a), whereby the first working plate (10) is rotated about a second rotation axis (B). Thus, a first rotation axis (A) is upwardly rotated about the second rotation axis (B), to further upwardly move a lower mold base (5). At this time, a lower mold (7) and an upper mold (4) are already in contact with each other, whereby a high thrust is caused between the molds (4, 7) to enable molding/joining of metal plates or the like. Consequently, it is possible to provide a press working machine which can embody both of a low-thrust/high-speed area and a high-thrust/low-speed area through only a single air cylinder. <IMAGE></p> |
