Pressing at least one molding compound by means of several stamps

摘要

Method for pressing at least one pressing compound (11), in particular a friction lining compound for a brake lining (100), by means of a pressing tool (200) with at least one pressing chamber and several pressing dies (211a, 211b) assigned to this pressing chamber (210), and applying the pressing compound ( 11) on a carrier plate (10), the individual press punches (211a, 211b) being individually controllable, characterized in that the individual press punches (211a, 211b) are acted upon at different temperatures, the plurality of press punches (211a, 211b) several pressing compounds (11, 11a) with different chemical compositions are pressed and arranged on the carrier plate (10), the method comprising the following steps: a) placing a first pressing die (211a) in such a way that a first receiving area (13) within the Press chamber for receiving the molding compound (11) is formed; andb) introducing the molding compound (11) into the first receiving area (13); andc) applying a pressure plate (212) or the carrier plate (10) to an opening of the pressing chamber and / or immersing the pressure plate (212) or the carrier plate (10) in the pressing chamber, and pressing the pressing compound (11) together in the first receiving area (13 ) by lifting movement of the pressure plate (212), the carrier plate (10) and / or the first press ram (211a), the press compound (11) being pre-compressed; andd) placing a second press ram (211b) in such a way that a second receiving region (14) is formed within the press chamber for receiving a further press compound (11a); ande) introducing the further molding compound (11a) into the second receiving area (14); andf) applying the pressure plate (212), a further pressure plate (212a) or the carrier plate (10) to the opening of the pressing chamber and / or immersing the pressure plate (212), the further pressure plate (212a) or the carrier plate (10) in the Pressing chamber, and pressing together the further pressing compound (11a) in the second receiving area (14) by lifting movement of the pressure plate (212), the further pressing plate (212a), the carrier plate (10) and / or the second pressing die (211b), the further pressing compound (11a) is pre-compressed; and wherein at least during steps b) and c) the second press ram (211b) is arranged as a placeholder for the second receiving area (14) within the press chamber.
