PURPOSE: To provide a hydraulic press by which a large working capacity can be displayed with a simple and inexpensive structure and by a small drive cylinder, and a slide can be driven at a high speed.
CONSTITUTION: In a hydraulic press, the bases of first links 3a and 3a' extending to the right and the left, are pivotaly mounted on the piston rod 2a of a hydraulic cylinder 2 for driving, which is mounted on the upper part of a press frame. On the other hand, a pair of second links 3b and 3b' with the bases pivotaly mounted, is provided on the press frame 1 to the right and the left. A pair of third links 3c with the bases pivotaly mounted, is provided on a slide 1e to the right and the left.
