Abstract
A cutting and shaping press comprises one or more drivers. The piston rod of the individual drive cylinder is connected to a hinged lever drive for a press ram. The drive cylinder is fixed on a bridge which connects two slide plates together. These slide plates are arranged inside the press ram and each have in the center a guide for a multiple pivot carrier. The press ram is open upwardly towards the drive cylinder and slide with its lateral surfaces, which are enclosed on all sides, along guides which are fitted in fixed positions on the inner sides of a press stand.
Claims16
A cutting and shaping press comprising a press ram, a press stand, at least one drive cylinder having a piston rod, and a hinged lever drive having at least two knee lever systems connected to the ram and symmetrically arranged with respect to a vertical center plane of the ram, the knee lever systems having fixed points and at least two threaded spindles adjustable in height in the press stand and positioning bearing blocks fitted on ends of the threaded spindles for pivoting one of the fixed points of each of the knee lever systems, the press further comprising a slide device within the press ram, a multiple pivot carrier connected to the piston rod of the drive cylinder, and a connecting rod connecting the multiple pivot carrier to a knee joint of each of the knee lever systems, characterized in that the multiple pivot carrier is guided by a structure in the press ram and that the slide device connected to said bearing blocks is supported in the press ram.
A cutting and shaping press comprising a press ram, a press stand, at least one drive cylinder having a piston rod, and a hinged lever drive having at least two knee lever systems connected to the ram and symmetrically arranged with respect to a vertical center plane of the ram, the knee lever systems having fixed points and at least two threaded spindles adjustable in height in the press stand and positioning bearing blocks fitted on ends of the threaded spindles for pivoting one of the fixed points of each of the knee lever systems, the press further comprising a slide device within the press ram, the slide device having a multiple pivot carrier connected to the piston rod of the drive cylinder, and a connecting rod connecting the multiple pivot carrier to a knee joint of each of the knee lever systems, characterized in that the multiple pivot carrier is guided in the press ram, the slide device is supported in the press ram, and the slide device is defined by a bridge for the drive cylinder as well as by slide plates connected with one another and guided in the press ram.
A cutting and shaping press comprising a press ram, a press stand, at least one drive cylinder having a piston rod, and a hinged lever drive having at least two knee lever systems connected to the ram and symmetrically arranged with respect to a vertical center plane of the ram, the knee lever systems having fixed points and at least two threaded spindles adjustable in height in the press stand and positioning bearing blocks fitted on ends of the threaded spindles for pivoting one of the fixed points of each of the knee lever systems, the press further comprising a slide device within the press ram, the slide device having a multiple pivot carrier connected to the piston rod of the drive cylinder, and a connecting rod connecting the multiple pivot carrier to a knee joint of each of the knee lever systems, characterized in that the multiple pivot carrier is guided in the press ram and the slide device is supported in the press ram, characterized in that the press ram has an upper edge and sides, all of the sides of the press ram consisting of closed surfaces extending up to the upper end of the press ram, the press stand has an inside and corners, and said press ram is open towards the drive cylinder and slides with its sides along guides fitted in fixed positions on the inside of and near the corners of the press stand.
