Abstract (en)
[origin: EP1762313A1] The second tool (W2) has rigid connections with the drive. The rigid connection comprises traverses joining them. These are in the form of flat links. The traverse overlaps a tool (W1) between the drive (A) and the other tool (W2). One tool (W1) is connected to the other (W2) through a synchronous lever arrangement (16.1, 16.2). The synchronous lever assembly includes a synchronous balance (18) with fixed rotation center (19) and two ends. These are pivoted to synchronous levers (16.1, 16.2), one connected to the first tool and the other to the second tool. The rotation center is at the height of the workpiece. The drive (A) includes a piston cylinder unit (3), the cylinder being arranged on a plate (5). The cylinder plate can be moved along tie bars (2.1, 2.2). A spindle (12) penetrates the drive, which is connected to the tool (W1). The spindle penetrates the piston with an external thread, which engages an internal thread in the piston. The tools can also be moved along the tie bars. Each tool is in a casing. One casing is a feed casing (8). The casing rigidly connected to the drive serves as a hollow casing (9). Tie bars extend between the outer plates (13, 14). The spindle (12) penetrates an adjustment collar (11) in an outer plate (13).
