PCT No. PCT/EP87/00315 Sec. 371 Date Feb. 22, 1988 Sec. 102(e) Date Feb. 22, 1988 PCT Filed Jun. 17, 1987 PCT Pub. No. WO87/07870 PCT Pub. Date Dec. 30, 1987.The invention relates to an articulated lever press consisting of a press stand (1.1) and a frame-shaped press slide (2.1), the slide (2.1) possessing a hydraulic cylinder drive (2.12) which is arranged on it and is connected to the multi-articulated support (2.7) guided in the center of the press in the slide (2.1), and at least two connecting rods (2.8) are movably arranged on the said multi-articulated support, the other ends of the said connecting rods each engaging one of the two articulated levers (2.10) or (2.11) which are mounted on the slide (2.1) and on the press frame (1.1) so that their height can be adjusted. The object is essentially to keep the working range of the slide (2.1) adjustable, irrespective of the slide travel and while maintaining slide guidance. It is proposed that the press stand (1.1) be a twin-stand frame partially closed even at the front and end. The working range of the slide (2.1) in the stand (1.1) is supported and adjusted by synchronously driven shafts (2.2) which are coordinate with the stand (1.1) via guide beams (2.4) provided with shaft bearings (2.3). The guide beams (2.4) are provided on the lower surface with bearings (2.3.1) to permit the suspension of the pair of articulated levers (2.10/2.11) which are to be connected to the slides (2.1) and (2.9). (FIG. 2).
