Japanese Patent JP6676652
Kind Code:
B2
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.
