Abstract (en)
[origin: EP0305566A1] In the press, there is provided in a press body a press frame 63 and a press table 62 which are interconnected so as to be engaged in terms of movement by means of a drive and form a main press ram. A hydraulic press part 64 having two additional press shafts is provided upstream of the main press ram between the press frame 63 and the press table 62. A hydraulic coupling device 74, 75, 76, which has a variable transmission ratio, makes it possible to actuate and/or control the second hydraulic press shaft of the hydraulic press part 64 by means of the first press shaft of the latter, whereas the first press shaft of the hydraulic press part can in turn be actuated by means of the press frame 63 of the main press ram. The movement ratios of the second press shaft of the hydraulic press part 64 can, as a result, be varied relative to the main press shaft. <IMAGE>
