Abstract:
1. A press ( 1 ) including first components ( 16 , 17 ) consisting of an upper tool part ( 16 ) and a lower tool part ( 17 ), a press table ( 6 ) in supportive relationship with the lower tool part ( 17 ), a plunger ( 7 ) in supportive relationship with the upper tool part ( 16 ), means for adjusting during set-up of the press ( 1 ) the effective overall rigidity of the upper tool part ( 16 ) and the plunger ( 7 ) and/or the lower tool part ( 17 ) and press table ( 6 ) between at least two selectable rigidity values, the means for adjusting during set-up of the press ( 1 ) the effective overall rigidity of the upper tool part ( 16 ) and the plunger ( 7 ) and/or the lower tool part ( 17 ) and the press table ( 6 ) between at least two selectable rigidity values includes the press table ( 6 ) includes a slidable table ( 44 ) and at least one of a stiffening structure ( 47 ) for contact with the slidable table ( 44 ) for increasing the effective rigidity of the slidable table ( 44 ) and a reinforcing element ( 48 ) for increasing further the effective rigidity of the slidable table ( 44 ) and an additional component ( 23 ) removably positioned between the at least one stiffening structure ( 47 ) and the reinforcing element ( 48 ) for providing an adjustable rigidity of the reinforcing element ( 48 ).
