Patent ID: 8857327

Claim:
A structure for presses for forming ceramic products, comprising: a resistant structure constituted by at least one resistant element ( 1 ) which, in turn, comprises a flat annular element or arch ( 2 ), internally of which are predisposed two facing surfaces ( 20 ), diametrically opposite one another, between which at least a power organ ( 5 ) is inserted, which power organ ( 5 ) is destined to exert a pressing action by compressing an object or material to be pressed between two bodies to unload on the facing surfaces ( 20 ) equal and opposite reactions of the pressing action; full-thickness cuts ( 3 ) being provided at the ends of the facing surfaces ( 20 ), wherein each full-thickness cut ( 3 ) exhibits a predetermined width and starting from the end of the relative facing surface ( 20 ) develops over a curved portion which exhibits at least a first tract ( 22 ) a most external surface of which connects with a lateral surface ( 24 ) of a vertical or nearly-vertical portion of the annular element ( 2 ) or arch which laterally delimits a space internally of which the power organ ( 5 ) is housed, and at least a second tract ( 23 ) which is connected to the first tract ( 22 ) and exhibits a concavity which has the same direction as the first tract ( 22 ); the full-thickness cuts ( 3 ) being arranged symmetrically at least with respect to a median vertical axis of the annular element ( 2 ) or arch which is perpendicular to the facing surfaces ( 20 ); at least a plate ( 4 ) being housed in each full-thickness cut ( 3 ) which plate ( 4 ) is provided with opposite surfaces that are destined to contact reciprocally-facing surfaces which delimit each full-thickness cut ( 3 ).
