Abstract (en)
[origin: WO2011054485A1] The invention relates to a press (21) with at least one press frame (9), a platen mounted therein and a ram (5) driven by means of at least one crank drive (12), wherein an upper mould part (6) is arranged on the ram (5) and a lower mould part (7) is arranged on the press platen (8), wherein at least one crankshaft (1) with at least one crank pin (2) and at least one connecting rod (3) is arranged as the crank drive (12), and wherein at least one direct drive, driving the crankshaft (1) directly, is arranged as the motor (14) for driving the crankshaft (1). The object of the invention is to provide a press in which the input-side forces of the direct drive can be passed on on the output side with much less loading for the crankshaft, and at the same time the overall stiffness of the drive train is increased significantly and/or the overall length of the drive train is minimized. The invention consists in that, with at least one motor (14) arranged within a press (21) with at least two connecting rods (3) on at least one crankshaft (1), at least one motor (14) is arranged between the connecting rods (3).
