    Description

    [0100] The invention is explained in more detail below with reference to an exemplary embodiment. In the drawings:

    [0101] FIG. 1 shows a schematic simulation system for selecting an alloy and a manufacturing method for a workpiece to be manufactured having amorphous properties;

    [0102] FIG. 2 shows a schematic illustration of a manufacturing unit, and

    [0103] FIG. 3 shows a schematic illustration of a tool.

    [0104] FIG. 1 shows a schematically illustrated simulation system 2. The simulation system 2 is designed to select an alloy and a manufacturing method for a workpiece 4 to be manufactured (cf. FIG. 4) having amorphous properties.

    [0105] For this purpose, the simulation system 2 according to FIG. 1 comprises an input unit 6 which is used to input a requirements profile A for the workpiece 4 to be manufactured. This makes it possible for a user to provide the required properties of the workpiece 4 to be manufactured in the form of the requirements profile A to the simulation system 2 or to feed the simulation system 2 with the requirements profile A.

    [0106] Furthermore, the simulation system 2 comprises at least one memory unit 8 which is designed to store information data I, wherein the information data I specify information concerning physical and/or chemical and/or mechanical properties of a plurality of alloys L for producing workpieces 4 and information concerning manufacturing methods V. For this purpose, the memory unit 8 can have, for example, a plurality of partitions and/or can be designed in multiple parts, i.e. composed of a plurality of sub-memory units. Furthermore, the memory unit 8 is communicatively and bidirectionally connected to an analysis unit 10.

    [0107] In this case, the analysis unit 10 is designed to simulate a plurality of workpieces 4 according to the requirements profile A and the information data I. This is used to create simulation data. Furthermore, the analysis unit 10 is configured to assess the simulated workpieces on the basis of the simulation data and the requirements profile A, before of an alloy L and a manufacturing method V which are particularly suitable with regard to the requirements profile A of the workpiece 4 to be manufactured are selected on the basis of the assessment.

    [0108] In order to realize the above method steps, the analysis unit 10 comprises a calculation unit 12, by means of which properties of the workpiece to be manufactured that are specified by the requirements profile A are calculated. Furthermore, the analysis unit 10 comprises a first simulation unit 14. By means of the first simulation unit 14, a simulation of a mechanical load on the workpiece 4 to be manufactured takes place on the basis of and according to the requirements profile A and the calculated properties. Subsequently, the information concerning the simulated mechanical load is added to the simulation data.

    [0109] Analogously, the analysis unit 10 also comprises a second simulation unit 16 and a third simulation unit 18. A simulation of chemical properties of the workpiece 4 to be manufactured is carried out by means of the second simulation unit 16 according to the requirements profile A and the information data I. By means of the third simulation unit 18, manufacturing of the workpiece 4 is simulated by means of the manufacturing methods V contained in the memory unit 8. Both the information concerning the chemical properties, which is provided by the second simulation unit 16, and the information concerning the simulated manufacturing, which is generated by the third simulation unit 18, are subsequently added to the simulation data and used for a selection of a suitable alloy L and of a suitable manufacturing method V as part of the assessment by the analysis unit 10. The selection and the assessment are carried out in such a way that the alloy L and the manufacturing method V which fulfill or at least substantially fulfill the properties of the workpiece 4 to be manufactured, defined by the requirements profile A, are selected. If a plurality of alloys L and/or a plurality of manufacturing methods V come into consideration, the analysis unit 10 selects the alloy L and the manufacturing method V which are most suitable with regard to higher-level preferences, for example with regard to cost efficiency.

    [0110] After the selection of the suitable alloy L and the suitable manufacturing method V by the analysis unit 10, the selected alloy L and the selected manufacturing method V are output by an output unit 20. The output unit 20 can, for example, be an optical output unit 10 in which the output is effected on a screen.

    [0111] According to one embodiment, the analysis unit 10 is designed to generate a data pair by associating the selected alloy L and the selected manufacturing method V with the requirements profile. In this case, the generated data pair is stored in the memory unit 8. If a requirements profile A stored in the memory unit 8 is now input, an alloy L associated with the requirements profile A and a manufacturing method V associated with the requirements profile A are specified, without a simulation taking place.

    [0112] In one embodiment, it is conceivable for the simulation system 2 to have an artificial neural network to optimize the selection of the suitable alloy L and/or the suitable manufacturing method V.

    [0113] FIG. 2 shows a schematic illustration of a manufacturing unit 38, which is designed as an AMM (amorphous metal) injection-molding plant. The manufacturing unit 38 comprises a mold in the tool 40 and a melting chamber 42. The melting chamber 42 is supplied with a solid alloy segment of an amorphously solidifying alloy (blank) 44 by a robot and is placed centrally in an induction coil 46. The blank 44 (“4” instead of “44” in the figure) is heated within the melting chamber 42 by means of a heating element, in particular an induction field which is generated by the induction coil 46. The blank 44 is a solid alloy segment of an amorphously solidifying alloy. The alloy segment 44 comprises, for example, a certain amount of palladium, platinum, zirconium, titanium, copper, aluminum, magnesium, niobium, silicon and/or yttrium.

    [0114] The blank 44 is melted by the heating element or the induction coil 46, so that it is present in molten form. Preferably, the blank 44 is heated to a temperature of 1050° C. The molten material is injected into the tool 40 by a plunger 48.

    [0115] FIG. 3 shows the schematic structure of an injection-molding tool 40. The molding chamber 52 is filled with a melt by means of one or a plurality of openings 50 leading into a molding chamber 52 of the tool 40. The molding chamber 52 is designed as a negative mold of the workpiece 4 to be produced. In the exemplary embodiment of FIG. 3, it is provided that an opening 50 can be used to guide liquid material into the molding chamber 52. It can be advantageous to use a plurality of sprues for filling the molding chamber 52 in order to achieve a uniform temperature distribution and to reduce turbulence of the melt. A uniform temperature distribution and a small number of turbulences lead to a better cooling operation, to homogeneous cooling and thus to uniform amorphous material properties.

    [0116] The liquid material must rapidly cool down within the molding chamber 52 in order to prevent crystallization. The cooling of the liquid material depends greatly on the geometry of the component or workpiece 4 to be produced.

    [0117] The invention is not limited to the exemplary embodiment described above. Rather, other variants of the invention can also be derived therefrom by a person skilled in the art without departing from the subject matter of the invention. In particular, all individual features described in connection with the exemplary embodiment can also be combined with one another in another way without departing from the subject matter of the invention.
