Abstract:
1. A structure for presses, in particular for forming ceramic products, comprising: a resistant structure constituted by at least one resistance element ( 1 ) which in turn comprises a flat annular element ( 2 ) internally of which and in diametrically opposite positions two facing surfaces ( 20 ) are arranged, between which facing surfaces ( 20 ) at least one power tool ( 5 ) can be inserted, for exerting a pressing action and compressing between two bodies an object or a material to be pressed; the two facing surfaces ( 20 ) receiving equal and opposite reactions to forces developing during the pressing action; cuts being made at ends of the facing surfaces ( 20 ) which cuts involve a total thickness of the facing surfaces ( 20 ); each of the cuts comprising a first tract ( 22 ) which is parallel to a pressing direction and a second part ( 23 ) which is circular in shape; the cuts being arranged symmetrically with respect to a median axis of the annular element ( 2 ) which median axis is perpendicular to the annular element and the facing surfaces ( 20 ); the first tracts ( 22 ) of cut identifying first lateral surfaces ( 25 ) which laterally delimit two opposite central portions ( 26 ) of the annular element ( 2 ) bearing the surfaces ( 20 ); the circular second part ( 23 ) of cut constituting a snug seating for discs ( 24 ) and a centre of each central part ( 26 ) being located at a distance which is smaller than a distance between the first lateral surfaces ( 25 ); means for interpositioning being provided for being interpositioned between ends of the facing surfaces ( 20 ) so that two resultants, parallel to the pressing direction, of action exerted on each of the facing surfaces ( 20 ) are located externally to centres of corresponding circular second parts ( 23 ).
