    • The invention provides a servo press which can obtain a higher speed in a moving section of a slide, and a higher pressure in a pressurizing section near a bottom dead point without enlarging a capacity of a motor. The servo press is provided with a multi-toggle mechanism 10 moving up and down a slide 5 in which an upper die is to be fixed to a lower surface of the slide, and a toggle driving mechanism 20 provided on a crown 6 located to an upper side of the slide and driving the multi-toggle mechanism. The multi-toggle mechanism 20 is structured such as to include three or more toggles generating a force amplifying effect by a plurality of links 11, 12, 13, 14.

    • Die Erfindung bezieht sich auf schnellaufende mechanische Pressen, insbesondere Schnellschneidpressen. Gegenstand der Erfindung ist ein Pressenantrieb mit zwei Exzenterwellen (10), die über Pleuel (11) mit einem Stößel (39) verbunden sind. Für einen vollständigen dynamischen Massenausgleich sind Massenausgleichsgewichte (33, 34) vorgesehen, die über weitere Lenker angelenkt sind und gegenläufig zu dem Stößel (39) bewegt werden. Hiervon ausgehend besteht die Erfindung im wesentlichen darin, daß symmetrisch zu den Exzenterwellen (10) mindestens die doppelte Anordnung eines ersten, nahezu waagerecht angeordneten Kniegelenkes (19 bis 22), eines zweiten, nahezu senkrecht angeordneten Kniegelenkes (25 bis 28) und eines dritten, nahezu senkrecht angeordneten Kniegelenkes (42 bis 45), die einerseits mit dem Stößel (39) und andererseits mit den Massenausgleichsgewichten (33, 34) verbunden sind, vorgesehen sind.

    • A pressworking operation on a workpiece or material which enables pressworking energy to be transmitted to the workpiece or material in a plurality of steps with there being no sudden increase in the coefficient of friction between the working tool and the workpiece or material after release of accumulated potential energy from an elastically deformable energy carrier and in which the velocity of displacement of the working tool does not change sign until completion of working of the workpiece or material is made possible by use of a press apparatus comprising a power cam (2) contacting a roll (1) attached to a quaternary lever (3) at one connection point of the lever, the quaternary lever being connected at a second hinged connection point (6) to a rigid support at a third connection point (4) to the elastically deformable member (9) connected in turn to a second rigid support (21), with the quaternary lever being connected at its fourth connection point (7) through a hinged connecting rod (10, 13) to a unit (14,18) carrying a part (19) of a working tool and capable of reciprocating movement. The cam (2) includes sections for enabling energy to be accumulated in the elastically deformable member (9) and for release of the energy therefrom over a shorter time period than the energy accumulating time period through the medium of the quaternary lever (3) operating as a functional force-varying member. The apparatus includes provision for effecting powered variation of the angle between the semirods (10, 13) independently of displacement which may be imparted to the unit (14, 18).
