Abstract
In a forming process with a press having in a frame a ram closing through the force of a cylinder with a moveable piston against a press table in a straight-line movement, the piston initially acts upon at least one knuckle joint system during the closing of the press, and a hydraulic cushion of the ram concludes the closing process with extension of the knuckle joint system in movement direction of the piston and straight-line support thereof against the frame. In a press having in a frame a ram closing through the force of a cylinder with a moveable piston against a press table in a straight-line movement, the ram is connected so as to be fixed with respect to the frame via at least two identically constructed knuckle joint systems, and the ram has a hydraulic cushion.

A forming process using a press having, in a frame, a ram closing through a force of a cylinder with a moveable piston against a press table in a straight-line movement, comprising:
- initially the moveable piston acts upon at least one knuckle joint system during a closing of the press;
- and
- concluding a closing process by a hydraulic cushion of the ram with extension of the knuckle joint system in a movement direction of the piston and straight-line support thereof against the frame.
A press comprising:
- a frame;
- a cylinder with a moveable piston;
- a press table;
- a ram arranged in the frame and configured to close through a force of the cylinder against the press table in a straight-line movement and having a hydraulic cushion;
- and
- at least two identically constructed knuckle joint systems configured to connect the ram to be fixed with respect to the frame;
- and in that the ram has a hydraulic cushion.
