  • Patent number: 10906262
    Abstract: The invention relates to a method of controlling a ceramic and/or metal powder press (1) for pressing a compressible material (6), wherein at least one electromotive drive (15, 16; 20, 21), which adjusts at least one punch (5; 4) along a pressing direction, is controlled in such a manner that the drive (15, 16; 20, 21) moves the punch (5; 4) along a setpoint positioning path (as1) and the drive is readjusted if it deviates from the setpoint positioning path (as1), wherein a measured force (F11, F12) acting on the compressible material (6), the punch (4) or its supporting components (17-19), is used as at least one control variable for readjustment. The invention also relates to a ceramic and/or metal powder press (1) configured to carry out the method.

  • Publication number: 20040195715
    Abstract: A controlling method for parallel controlling of a plurality of controllable tool devices is based on a procedure plan for a press lifting with respect to a press cycle, according to which pre-determined values for tool device parameters are determined and according to which a test lifting for examination of the controlling method will be started. For rationalisation of the method and in order to minimise technical faults as well as press standstill times, the test lifting is simulated as a virtual lifting in a computer device. In addition, to facilitate a long-term monitoring and analysis of changes with respect to the press and/or the tool during the pressing operation, at least one operation parameter may be registered, in order to be compared with earlier registered operation parameters.
