ABSTRACT:
The invention relates to a cutting and reshaping press with hydro-mechanical articulated lever drive in which a drive cylinder (3) for a ram (2) is supported by a bridge structure (5) located in a stanchion (1) between lateral guides (12). The bridge structure (5) is connected to the stanchion (1) by means of threaded spindles (4) capable of being adjusted in height. The bridge structure (5) constitutes the connection between two support axles (6) installed on either side symmetrically in relation to the middle of the press and a central guide (7) in which the piston rod (3.1) travels. At the end of piston rod (3.1) is an articulation point (10.4). The two support axles (6), together with additional connected articulation points (8 and 9) constitute rigid triangles (10) which are pivotable about support axles (6). The articulation point (9) oriented towards the center of the ram (2) is connected by two coupled drive lever elements ( 10.2 and 10.2) to articulation point (10.3) located in curves (7.1) and articulation points (10.4) in the central guide (7).
