<p>Press for manufacturing molded or pressed products, comprising a press tool (3) fixed at one end of a moving cylinder (2). Said moving cylinder (2) is coaxially mounted inside a fixed guiding cylinder (4) fixed and coaxially suspended inside a cylinder (5) forming the outer envelope of the press. The press has a moving wall (8) defining a first variable volume chamber, eight hydraulic jacks (11a-11h) with free differential pistons (12a-12h) arranged in crown about the central cylinder (2). The outer envelope (5) comprises a widening (23) provided with at least a bore (44) wherein are arranged explosion means to cause the displacement of the press tool (3) when the press is used as a combined pneumatic/explosion press. The press has reduced overall dimensions, and may be adapted to the manufacture of different articles at various working rates by simple and fast modifications. </p> |
