Definitions
- a press or a punching machine with at least two eccentric shafts which are arranged in the head piece of the press and which drive at least one ram via several connecting rods.
- the at least two eccentric shafts are arranged perpendicular to one another. The two eccentric shafts are therefore in a normal position on one another.
- Each eccentric shaft can then, for example, drive two connecting rods.
- each eccentric shaft has its own drive. This can be a servo drive or a conventional drive that is connected to the eccentric shaft via a single-stage or two-stage planetary gear. It is advantageous if the intersection point of the two continuous eccentric shafts is located centrally above the tappet center. It is also advantageous if, in the case of split eccentric shafts, the intersection point of their axes of rotation is located centrally above the tappet center.
- FIG. 2 is a detailed view of the head of the press from Figure 1;
- Fig. 4 is a plan view of the headpiece of Fig. 3;
- Fig. 12 and 13 different drive concepts for a press according to the invention with two eccentric shafts;
- the eccentric shafts 5, 6, 7 can be driven by a simple planetary gear 21 or by two gear stages 29.
