Abstract (en)
[origin: WO2015107082A1] The invention relates to a device for the compacting, in particular the harmonic compacting, of mineral mixtures, in particular concrete mixtures in the production of all types of concrete products, or for deep drawing. The invention also relates to a machine frame (10) having a machine head (12), a machine table (14), and at least two side elements (16a, 16b) connecting the machine head (12) and the machine table (14). A first piston-cylinder assembly (39), which is connected to the machine table (14), is designed in such a way that lifting and lowering forces are exerted on a form element (42, 24) that can be filled with mineral mixture, in particular with concrete mixture, or a form element on which a sheet metal or plastic blank can be laid, said piston-cylinder assembly also being designed to lift and/or lower and/or vibrate the form element (42, 24). A second piston-cylinder assembly (44), which is connected to the machine head (12), is designed in such a way that a punch (58), which can enter into the form element (42, 24), is held using a holding force greater than or equal to the maximum lifting force of the first piston-cylinder assembly. The invention also relates to a method for compacting or deep drawing using the device.
