<p>The press has a working cam in an upper press tool to operate a passive cam (6) in a lower press tool (1), which has e.g. a punch die (5) fastened to it. The lower tool has a slide guide base (7) and guide supports (8) for the cam, and parts to apply a force to the passive cam towards a side opposite to the work piece. The passive cam is fitted into the base so that it can be raised and removed, when the guide supports are withdrawn.</p> |
