Structure for presses, in particular for forming ceramic products

摘要

A structure for presses, a resistant structure of which includes at least a resistant element which, in turn, includes an annular element or arch, internally of which are predisposed two facing surfaces, between which at least a power organ is insertable, which power organ is suitable for compressing an object or material to be pressed between two bodies. Full-thickness cuts are symmetrically arranged at ends of the facing surfaces, each cut, starting from the end of the relative facing surface, develops over an arc of a polycentric curve which exhibits at least a first tract, the most external surface of which connects with the lateral surface of the vertical portion of the annular element or arch, and at least a second tract which is connected to the first tract and extends over a portion of not less than a quarter of an arc of circumference.

主权项

1. 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).
