[0001] The invention relates to a method for constructing at least one tool assembly having at least two tools. The invention also relates to a device for data processing. Furthermore, the invention relates to a computer program and a computer-readable storage medium. Background Art

[0002] US 9 922 345 B2 discloses a method implemented by a computer. In addition, a method implemented by a computer is known from US 8560 366 B2. Summary of the invention

[0003] The object of the present invention is to create a method, a device for data processing, a computer program and a computer-readable storage medium, which can particularly advantageously construct and subsequently produce, for example, at least one tool set having at least two tools for processing, in particular for modifying, components.

[0004] According to the invention, this object is achieved by a method having the features of claim 1, by a device having the features of claim 11, by a computer program having the features of claim 12, and by a computer-readable storage medium having the features of claim 13. Advantageous embodiments of the invention are the subject of the dependent claims.

[0005] A first aspect of the invention relates to a method for constructing and, for example, subsequently manufacturing at least one first tool set, which comprises at least or exactly two first tools. The first tool, and thus the first tool set, is provided for, is designed for, or is constructed and, in particular, manufactured for, in, in particular, a single stroke of a press, simultaneously processing, in particular reshaping, in particular deep drawing and / or trimming, in particular punching out at least two first components. This means that, for example, a hydraulic or mechanical press comprises, in its fully manufactured state, a first tool set, and thus a first tool, wherein the first tool, and thus the first tool set, is constructed, in particular manufactured, in or by the method according to the invention. The construction of the first tool, and thus the construction of the first tool set, is also referred to as the design, in particular the structural design, of the first tool, and thus the first tool set. In particular, by means of the first tool, two first components can be processed simultaneously during the stroke of the press, so that during or during the stroke of the press, one of the first components can be processed or processed by means of one of the first tools, or the other of the first components can be processed or processed by means of the other of the first tools, wherein or at the same time, for example, the first components and thus in particular the first tools (in particular when viewed in or along a horizontal plane) are arranged side by side with each other. In particular, it is provided that during the stroke, processing of the one of the first components by the other of the first tools does not occur, and in particular, it is provided that during the stroke, processing of the other of the first components by the one of the first tools does not occur. For example, a plurality of tool groups in a press line or a punching line form a tool set. In other words, all tools of a press line or a punching line are also collectively referred to as a tool set and thus form a tool set.

[0006] In general, the components processed simultaneously or in parallel in one stroke of the press, in particular in the manner described above, form a combination, which is also referred to as a variant, a component variant or a component combination, so that, for example, with respect to the first tool and the first component, the first component forms a first combination, which is also referred to as a first variant, a first component variant or a first component combination. This will be explained in more detail based on the following example: In the large-scale or mass production of vehicles, for example, which are configured as motor vehicles, in particular automobiles, especially sedans, for example, both front hoods and rear hoods are manufactured for a vehicle series or for a vehicle derivative, so that a plurality of individual vehicles of the corresponding vehicle series or the corresponding derivative vehicles are manufactured from the manufactured front hoods and from the manufactured rear hoods. Therefore, in its completely manufactured state, the corresponding vehicle of the vehicle series, which is also referred to as the series for short, includes, in particular, exactly one of the manufactured front hoods and in particular, exactly one of the manufactured rear hoods. The corresponding front hood is manufactured, for example, from at least one corresponding front hood component, and the corresponding rear hood is manufactured, for example, from at least one corresponding rear hood component. For this purpose, for example, the corresponding front hood component and the corresponding rear hood component are processed, in particular reshaped and / or trimmed. In order to save time and cost to manufacture the front cover and the rear cover, and thus manufacture the vehicle, for example, in particular, just one of the front cover components and in particular, just one of the rear cover components form a processed, in particular, just one corresponding component combination. This should be understood as, in one stroke of a press (for example, the press mentioned above), the corresponding front cover component of the corresponding component combination and the corresponding rear cover component of the corresponding component combination are processed by means of corresponding tools at the same time, especially when, for example, the front cover component of the component combination and the rear cover component of the component combination (especially viewed along a horizontal plane) are arranged side by side with each other. In this example, the front cover component can be regarded as one of the first components, and the rear cover component can be regarded as another of the first components. Correspondingly, for example, the tool used to process the corresponding front cover component of the corresponding component combination and the corresponding rear cover component of the corresponding component combination can be regarded as the first tool. The processing of the components can also be simplified as the processing of the corresponding component combination, and vice versa. In other words, if it is mentioned below that one or a corresponding component combination is processed, processed or has been processed, it should be understood that the components of the component combination are processed, processed or have been processed.

[0007] Normally, a tool set and thus a tool are newly developed, configured and manufactured for a newly developed and thus newly manufactured vehicle of a vehicle series, which is usually a time-consuming and cost-intensive process. As will be explained in more detail below, the method according to the invention makes it possible to use production processes that have already been carried out and thus in the past, in which or by means of which component combinations are processed, in order to thereby manufacture, for example, vehicles of an earlier vehicle series.

[0008] That is, in order to be able to construct and, for example, subsequently manufacture the first tool and thus the first tool set particularly in a time-saving and cost-effective manner, it is provided in the method according to the invention that at least one corresponding performance characteristic value belonging to the respective manufacturing process is determined for a plurality of already executed manufacturing processes, in particular by means of an electronic computing device. This preferably means that the method is executed by the electronic computing device. The corresponding performance characteristic value belonging to the respective manufacturing process characterizes or describes the respective manufacturing process to which it belongs and thus to which the corresponding performance characteristic value belongs, in particular with regard to the successful execution of the respective manufacturing process and / or with regard to the productivity of the respective manufacturing process. In particular, the manufacturing process can be the previously mentioned production process used in the method. The feature that the manufacturing process is already executed or has been executed is to be understood as meaning that, in particular with regard to a first moment of execution, in particular of the start of the method according to the invention, the manufacturing process is in the past, i.e. before the first moment, and in particular ended or has been ended before the first moment, and is therefore completed or has been completed.

[0009] The corresponding manufacturing process that has been performed includes at least one corresponding process that belongs to the corresponding manufacturing process. In particular, when observed over a time period, in the corresponding manufacturing process, the corresponding process has been performed multiple times in succession. In the corresponding process of the corresponding manufacturing process, in the corresponding stroke of the aforementioned press or another press, at least two other components have been processed, in particular reshaped, in particular deep-drawn and / or trimmed, in particular punched out, by means of two other component tools of the corresponding other tool group at the same time. This should be explained according to the following example: For example, the corresponding two other components are or were corresponding semi-finished products, such as sheet blanks, in particular metal sheet blanks. For example, in the corresponding process, the corresponding two sheet blanks have been placed in the press or another press and processed by the corresponding stroke of the press or another press at the same time by means of two other tools, so that the corresponding two sheet blanks are simultaneously reshaped, in particular deep-drawn and / or trimmed, in particular punched out. Therefore, the corresponding two sheet blanks form a corresponding component combination in the corresponding process. Furthermore, the method according to the invention provides that the first tool set, and thus the first tool, is configured and in particular produced as a function of the determined performance characteristic value, in particular by means of an electronic computing device.

[0010] Typically, tool sets, and thus tools for tool sets, are constructed, in particular, based solely on human experience. This may result in the need to build multiple, possibly time-consuming and cost-intensive prototypes and / or to perform test sequences, in order to, for example, construct a first tool, and thus a first tool set, so that the first component can be processed as desired, i.e., in particular sufficiently time-saving and cost-effectively and with sufficient quality, with the aid of the first tool set. This may result in a time-consuming and cost-intensive process. In contrast, the present invention now enables the use of already executed processes, and thus of already executed manufacturing processes, or in other words, the use of already executed processes and manufacturing processes, in order to thereby, i.e., to create at least one advantageous starting point from the performance characteristic values, so that from this starting point the first tool, and thus the first tool set, can be manufactured in a time-saving and cost-effective manner and in particular subsequently, so that in particular after the manufacture of the first tool set, and thus the first tool, the first component can be processed advantageously, in particular in a time-saving and cost-effective manner.

[0011] The performance characteristic value may be or include a performance characteristic number, or may also be referred to as a performance characteristic number, wherein the corresponding performance characteristic number is also referred to as a KPI (key performance indicator). The performance characteristic number, for example, characterizes or describes whether and / or how often a stroke of the press or another press is executed without interference in a manufacturing process, in particular in its corresponding execution. Alternatively or additionally, the performance characteristic value describes or characterizes, for example, the output power per hour, that is, the number of strokes in the production per task time (Auftragszeit). Alternatively or additionally, the performance characteristic value describes or characterizes the stroke output per hour and / or a performance indicator in particular for each facility and time period. Alternatively or additionally, the performance characteristic value describes or characterizes, for example, a first inspection pass rate, which is obtained by dividing a difference by the actual amount, wherein the difference is obtained by subtracting the amount of scrap (thus the amount of scrap parts minus the amount of rework) from the actual amount, that is, the first inspection pass rate is the share of the parts delivered directly to the customer or buyer by each facility in the produced parts (especially taking into account rework). In particular, the performance characteristic value describes or characterizes, for example, the error-free execution or the degree of error-free execution of a manufacturing process. In particular, it is conceivable that the performance characteristic value describes or characterizes the scrap rate and / or the rework expenditure and / or the productivity of a manufacturing process.

[0012] By taking into account the manufacturing processes that have already been carried out, for example, at least or exactly one of the manufacturing processes that have already been carried out can be used as a reference process. In particular, it should be understood that the other tools used in the reference process can be used in particular as an initial basis, from which the first tool can be constructed and then manufactured in particular in a time-saving and cost-effective manner. Thus, for example, it can be avoided to start constructing the first tool part too much based on experience and / or based on chance. In particular, the manufacturing process and thus the component combination processed in the manufacturing process are evaluated (in particular relative to each other), for example, by performance characteristic values. This evaluation makes it possible to create a favorable initial basis, from which the first tool and then the first tool set can be constructed and then preferably manufactured in a time-saving and cost-effective manner. Therefore, the present invention makes it possible to use the evaluation of the manufacturing process and then the evaluation of the component combination in order to construct the first tool and then the first tool set, and then design another new manufacturing process, in which the first component is processed or can be processed by means of the first tool.

[0013] In order to be able to create a particularly advantageous initial basis for the construction of the first tool and thus the construction of the first tool set, so that the first tool and thus the first tool set can be constructed and in particular subsequently manufactured in a particularly time-saving and cost-effective manner, it is provided in one embodiment of the invention that an order of performance characteristic values ​​is created according to a predetermined or predeterminable rule, in particular by means of an electronic computing device, wherein the first tool set, i.e. the first tool, is constructed according to the order of the performance characteristic values. For example, the manufacturing process with the largest or smallest performance characteristic value is used as a reference process. In particular, for example, the first or last manufacturing process in the order of the performance characteristic values ​​is used as a reference process, so that the first tool and thus the first tool set can be constructed and in particular subsequently manufactured in a particularly time-saving and cost-effective manner. The order of the performance characteristic values ​​is also referred to as the performance characteristic value order.

[0014] For example, in the performance characteristic value sequence, the performance characteristic values ​​are sorted, in particular so that they are sorted in ascending or descending order. For example, if the largest performance characteristic value is optimal when sorting in ascending order, then for example the last performance characteristic value in the performance characteristic value sequence or the manufacturing process characterized by the last performance characteristic value in the performance characteristic value sequence is used as a reference process. This can be the case in particular when the respective performance characteristic value characterizes the respective quality of the respective associated manufacturing process. For example, if the largest performance characteristic value is optimal when sorting in descending order, then for example the first performance characteristic value in the performance characteristic value sequence or the manufacturing process characterized by the first performance characteristic value in the performance characteristic value sequence is used as a reference process. This can be the case in particular when the respective performance characteristic value characterizes the respective quality of the respective associated manufacturing process.

[0015] For example, if the smallest performance characteristic value is optimal when the performance characteristic values ​​are sorted in ascending order, then, for example, the first performance characteristic value in the performance characteristic value sequence or the manufacturing process characterized by the first performance characteristic value in the performance characteristic value sequence is used as the reference process. This can be the case in particular when the respective performance characteristic value characterizes the scrap rate or the cycle time of the respective associated manufacturing process. For example, if the smallest performance characteristic value is optimal when the performance characteristic values ​​are sorted in descending order, then, for example, the last performance characteristic value in the performance characteristic value sequence or the manufacturing process characterized by the last performance characteristic value in the performance characteristic value sequence is used as the reference process. This can be the case in particular when the respective performance characteristic value characterizes the scrap rate or the cycle time of the respective associated manufacturing process.

[0016] Another embodiment is distinguished in that, in particular by means of an electronic computing device, a first manufacturing process of the manufacturing process is assigned to a first manufacturing process type according to at least one first criterion. It is further provided that, in particular by means of an electronic computing device, a second manufacturing process of the manufacturing process is assigned to a second manufacturing process type according to at least one second criterion. The manufacturing processes are thus divided into different manufacturing process types according to the criterion. This makes it possible to achieve an advantageous comparability, in particular so that, for example, only those manufacturing processes are considered whose other components are identical or at least similar to each other and / or with respect to the first component to be manufactured. As a result, the first tool and thus the first tool set can be constructed in a particularly time-saving and cost-effective manner.

[0017] For example, the corresponding criterion includes the corresponding name or mark of the corresponding component. Therefore, if the name or mark of the other components processed in the process of the first manufacturing process is the same, the first criterion is met. Correspondingly, for example, if the name or mark of the other components processed in the process of the second manufacturing process is the same, the second criterion is met.

[0018] In another particularly advantageous embodiment of the invention, it is provided that the first manufacturing process is assigned to the first manufacturing process type if a first criterion is met. In this case, the first criterion is met if at least one difference between the first value and the second value is less than a predeterminable or predetermined threshold value. The first value characterizes or describes at least one of the other components that have been processed in the process of the first manufacturing process. Alternatively or additionally, the first value characterizes or describes at least one of the first manufacturing processes. The second value describes or characterizes another of the other components that have been processed in the process of the first manufacturing process. Alternatively or additionally, the second value characterizes or describes at least another of the first manufacturing processes.

[0019] Alternatively or additionally, the first criterion is met, for example, if at least one difference between the corresponding value (also referred to as the first comparison value) and at least one value (also referred to as the first component value) is less than a predeterminable or predetermined threshold value. For example, the first comparison value characterizes or describes the corresponding further component that is processed in a corresponding step of the first manufacturing process. Alternatively or additionally, the first comparison value characterizes or describes the corresponding first manufacturing process, for example. For example, the first component value describes or characterizes at least or exactly one of the first components to be manufactured and / or a planned manufacturing process to be performed by means of the first tool, which manufacturing process, for example, includes a planned step in which at least one of the first components is processed by means of the first tool.

[0020] Furthermore, it is provided that the second manufacturing process is assigned to the second manufacturing process type if the second criterion is met, wherein the second criterion is met if at least one difference between the third value and the fourth value is less than a predeterminable or predetermined threshold value. The third number describes or characterizes one of the other components that has been processed in the process of the second manufacturing process. Alternatively or additionally, the third value characterizes or describes at least one of the second manufacturing processes. The fourth value characterizes or describes another of the other components that has been processed in the process of the second manufacturing process. Alternatively or additionally, the fourth value describes or characterizes at least another of the second manufacturing processes.

[0021] Alternatively or additionally, the second criterion is met, for example, if at least one difference between the corresponding value (also referred to as the second comparison value) and at least one value (also referred to as the second component value) is less than a predeterminable or predetermined threshold value. For example, the second comparison value characterizes or describes the corresponding further component that is processed in a corresponding step of the second manufacturing process. Alternatively or additionally, the second comparison value characterizes or describes the corresponding second manufacturing process, for example. For example, the second component value describes or characterizes at least or exactly one and / or planned manufacturing process of the first component to be manufactured.

[0022] This ensures, for example, that for the construction of the first tool set only those manufacturing processes are considered in which other components are processed which are at least similar or identical to one another and / or with respect to the first component to be manufactured. This makes it possible to achieve a particularly advantageous initial basis in a particularly time-saving and cost-effective manner, starting from which the first tool and thus the first tool set can be constructed and in particular subsequently manufactured in a particularly time-saving and cost-effective manner.

[0023] Thus, for example, the difference value characterizes or describes the similarity of the further components to one another and / or the similarity of the already processed further components to the first component to be manufactured or processed. These similarities describe, for example, the similarity with respect to the respective wall thicknesses of the components, in particular in the form of sheet metal thicknesses, so that, for example, only those production processes are considered in which components are or have had similar or identical wall thicknesses, in particular sheet metal thicknesses, with respect to one another and / or with respect to the first component. Thus, in summary and in short, the corresponding criterion is met if the further components are at least similar or identical to one another and / or if the further components are at least similar or identical to the first component.

[0024] It has proven to be particularly advantageous if the values ​​characterize the same property of the respective component and / or the respective manufacturing process. This means, for example, that the first value and the second value relate to the same property of one of the further components and one of the first component, so that the construction and in particular the production of the first tool can be shown to be particularly time-saving and cost-effective. The property of the respective manufacturing process can be or include, for example, the number of presses in a press line used in the respective manufacturing process, the respective type of the respective press, etc.

[0025] Another embodiment is distinguished in that the property is or includes a wall thickness (in particular of the respective component) and / or a material forming the respective component and / or a degree of modification and / or in particular an outer dimension. This makes it possible to ensure in a particularly time-saving and cost-effective manner that only those manufacturing processes which have already been carried out and are therefore in the past are taken into account, the components of which were at least once or are similar to the first component to be manufactured or processed.

[0026] Another embodiment is distinguished in that at least one overall characteristic value characterizing the respective manufacturing process type is determined for the respective manufacturing process type from the performance characteristic values ​​of the manufacturing processes assigned to the respective manufacturing process type. The overall characteristic value thus describes or characterizes the respective associated process type, so that these process types can be compared with one another particularly easily, quickly and simply.

[0027] In order to be able to construct and subsequently, for example, manufacture the first tool set in a particularly time-saving and cost-effective manner, provision is made in a further embodiment of the invention for the first tool set to be constructed as a function of the overall characteristic value.

[0028] In order to enable a particularly advantageous, simple and rapid comparison of the process types with one another, it is provided in another embodiment of the invention that an order of the overall characteristic values ​​(also referred to as the overall characteristic value order) is created according to a predetermined or predeterminable rule, in particular by means of an electronic computing device. The above and subsequent embodiments regarding the order of the performance characteristic values ​​can also be easily transferred to the order of the overall characteristic values ​​and vice versa.

[0029] It has been found to be particularly advantageous to construct the first tool set according to the sequence of the overall characteristic values. As a result, the first tool can be constructed and, for example, subsequently manufactured, in a particularly time-saving and cost-effective manner.

[0030] The manufacturing process and the process type will now be explained in more detail with reference to the following example: In a first manufacturing process, which is also referred to as a first turning process, for example, a hood outer part and a hood inner part for a first series of motor vehicles are manufactured. For this purpose, for example, two of the other components are processed simultaneously each time during the steps of the first turning process, so that one of the hood outer parts for the first series is manufactured from the first of the two other components each time, and one of the hood inner parts for the first series is manufactured from the second of the two other components each time. Since the steps of the first turning process are carried out multiple times in succession, a plurality of hood outer parts for the first series and a plurality of hood inner parts for the first series are manufactured in the first turning process or by means of the first turning process.

[0031] In the second manufacturing process, which is also referred to as the second flipping process, for example, a hood outer part and a hood inner part for a second structural series of motor vehicles are manufactured. For this purpose, for example, two of the other components are processed simultaneously each time during the steps of the second flipping process, so that one of the hood outer parts for the second structural series is manufactured from the first of the two other components each time, and one of the hood inner parts for the second structural series is manufactured from the second of the two other components each time. Since the steps of the second flipping process are performed multiple times in succession, a plurality of hood outer parts for the second structural series and a plurality of hood inner parts for the second structural series are manufactured in the second flipping process or by the second flipping process.

[0032] In a third manufacturing process, also referred to as the first wheel arch process, for example, a first wheel arch component and a second wheel arch component for a third series of motor vehicles are manufactured. For this purpose, for example, two of the other components are processed simultaneously in each step of the first wheel arch process, so that one of the first wheel arch components for the third series is manufactured from the first of the two other components each time, and one of the second wheel arch components for the third series is manufactured from the second of the two other components each time. Since the steps of the first wheel arch process are performed multiple times in succession, a plurality of first wheel arch components for the third series and a plurality of second wheel arch components for the third series are manufactured in or by the first wheel arch process.

[0033] In a fourth manufacturing process, also referred to as the second wheel arch process, for example, a third wheel arch component and a fourth wheel arch component of a fourth series of motor vehicles are manufactured. For this purpose, for example, two of the other components are processed simultaneously in each step of the second wheel arch process, so that one of the third wheel arch components for the fourth series is manufactured from the first of the two other components each time, and one of the fourth wheel arch components for the fourth series is manufactured from the second of the two other components each time. Since the steps of the second wheel arch process are performed multiple times in succession, a plurality of third wheel arch components for the fourth series and a plurality of fourth wheel arch components for the fourth series are manufactured in or by the second wheel arch process.

[0034] For example, the first flipping process and the second flipping process are first manufacturing processes assigned to a first process type. For example, the first wheel arch process and the second wheel arch process are second manufacturing processes assigned to a second process type.

[0035] For example, the first flipping process and the second flipping process are assigned to the first process type because, for example, the front cover outer part of the first flipping process and / or the front cover inner part of the first flipping process are similar or identical to the front cover outer part of the second flipping process and / or the front cover inner part of the second flipping process, and / or because the front cover outer part of the first flipping process and / or the front cover inner part of the first flipping process and / or the front cover outer part of the second flipping process and / or the front cover inner part of the second flipping process are identical or similar to the first component.

[0036] For example, the first wheel arch process and the second wheel arch process are assigned to the second process type because, for example, the first wheel arch component of the first wheel arch process and / or the second wheel arch component of the first wheel arch process are similar or identical to the third wheel arch component of the third wheel arch process and / or the fourth wheel arch component of the fourth wheel arch process, and / or because the first wheel arch component of the first wheel arch process and / or the third wheel arch component of the third wheel arch process and / or the fourth wheel arch component of the fourth wheel arch process are identical or similar to the first component.

[0037] In particular, it is conceivable that the corresponding previously mentioned sequence, and thus the sequence of the performance characteristic values ​​and / or the sequence of the overall characteristic values, is formed according to the similarities described between the other components and / or with respect to the first component. For this purpose, for example, the corresponding similarities, i.e., the corresponding similarity values, which describe the corresponding similarities, are used as weights, and thus as weighting factors, wherein, for example, the corresponding performance characteristic values ​​and / or the corresponding overall characteristic values ​​are multiplied by the corresponding weighting factors. Therefore, the corresponding similarities or the corresponding similarity values ​​can be components of the corresponding rules, according to which the corresponding sequence is formed. In particular, it is conceivable that each individual performance characteristic value and / or the overall value is weighted individually, so that, for example, the corresponding overall characteristic value is calculated from the individual weighted performance characteristic values, and / or the overall value of the upper level is calculated from the individual weighted overall characteristic values. For this purpose, for example, the weighted performance characteristic values ​​or the overall characteristic values, i.e., multiplied by the corresponding weighting factors, are added.

[0038] Of course, it is possible to determine multiple performance characteristic values ​​characterizing the corresponding manufacturing process for the corresponding manufacturing process, wherein the aforementioned and subsequent implementation plans regarding the corresponding performance characteristic values ​​of the corresponding manufacturing process can also be easily transferred to the multiple performance characteristic values ​​of the corresponding manufacturing process, and vice versa.

[0039] A second aspect of the present invention relates to a device for data processing, wherein the device for data processing comprises means for implementing the method according to the first aspect of the present invention. The advantages and advantageous embodiments of the first aspect of the present invention should be regarded as advantages and advantageous embodiments of the second aspect of the present invention, and vice versa.

[0040] A third aspect of the invention relates to a computer program, also referred to as a computer program product, which is also referred to as a program for short. The computer program according to the third aspect of the invention comprises instructions which, when implemented by a computer, cause the computer to perform the method according to the first aspect of the invention. The advantages and advantageous embodiments of the first and second aspects of the invention should be regarded as advantages and advantageous embodiments of the third aspect of the invention, and vice versa.

[0041] Finally, a fourth aspect of the present invention relates to a computer-readable storage medium, which includes instructions, which, when the computer-readable storage medium or the instructions are implemented by a computer, cause the computer to perform the method according to the first aspect of the present invention. The advantages and advantageous designs of the first, second and third aspects of the present invention should be regarded as the advantages and advantageous designs of the fourth aspect of the present invention, and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Further details of the invention are obtained from the following description of preferred embodiments together with the associated drawings. Here, it is shown:

[0043] Figure 1 A schematic side view of a press with a tool set comprising at least two tools, with the aid of which at least two components can be processed simultaneously in one stroke of the press; and

[0044] Figure 2 A block diagram is shown for illustrating a method for constructing a tool set for a press. DETAILED DESCRIPTION

[0045] In the figures, identical or functionally identical elements are provided with the same reference symbols.

[0046] Figure 1 A press 1 is shown in a schematic side view, which can be, for example, part of a press line. In particular, the press 1 can be designed as a mechanical press or a hydraulic press. The press 1 has two punching parts 2 and 3, which are also called die halves or are designed as die halves, which in particular are arranged in a manner similar to the embodiment of the present invention. Figure 1 In the initial position shown, the punches 2 and 3 are opposite each other. The press 1 can perform a stroke in which or during which the punches 2 and 3 are moved along the Figure 1 The movement directions indicated by the double arrows in the figure are moved relative to each other so that the punching parts 2 and 3 are moved towards each other.

[0047] exist Figure 1 In the embodiment shown, the punch 3 comprises a tool set 5, which is also referred to as a first tool set. The tool set 5 comprises two tools 6 and 7, which are referred to as first tools. With the aid of tools 6 and 7, two components 8 and 9, which are also referred to as first components, can be processed simultaneously, i.e. in parallel, during or in the stroke of the press 1. For this purpose, components 8 and 9 are arranged between the punches 2 and 3, in particular when the punches 2 and 3 are in their initial position, as viewed in the direction of movement. The press 1 then performs a stroke, whereby components 8 and 9 are processed simultaneously with the aid of tools 6 and 7. Figure 1It can be seen that the tools 6 and 7 and the components 8 and 9 are arranged next to each other, in particular during the stroke. Therefore, no processing of the component 8 by the tool 7 takes place during the stroke, and no processing of the component 9 by the tool 6 takes place during the stroke. In other words, with regard to the tools 6 and 7, the component 8 is processed only by means of the tool 6 during the stroke, and with regard to the tools 6 and 7, the component 9 is processed only by means of the tool 7 during the stroke. The processing of the respective components 8, 9 can, for example, include a reshaping, in particular a deep drawing, of the respective components 8, 9. Alternatively or additionally, the respective processing of the respective components 8, 9 can include a respective trimming, in particular a respective blanking, of the respective components 8, 9 and / or a respective profiling of the respective components 8, 9.

[0048] Components 8 and 9 form a combination 10, which is also referred to as a first combination. This combination is also referred to as a component combination, a first component combination, a variant, a first variant, a first component variant or a component variant. In short, the processing of components 8 and 9 in a stroke is also referred to as processing of the combination, and vice versa.

[0049] Now, in order to be able to construct and subsequently manufacture in particular the tools 6 and 7 and thus the tool set 5 in a particularly time-saving and cost-effective manner, a method for constructing and in particular for manufacturing the tool set 5 and thus the tools 6 and 7 is performed. In this regard, Figure 2 A block diagram is shown, based on which the method is explained below. In a first step S1 of the method, for a plurality of manufacturing processes that have been carried out and are therefore in the past with respect to the time point at which the method starts, at least one respective performance characteristic value belonging to the respective manufacturing process is determined, which performance characteristic value characterizes the respective associated manufacturing process. The method is carried out, for example, by means of an electronic computing device, by means of which, for example, the performance characteristic value is determined.

[0050] The respective manufacturing process that has been carried out and is thus in the past comprises at least respective steps, which have been carried out several times in succession in the respective manufacturing process, in particular when viewed over a period of time. In the respective steps of the respective manufacturing process, in the respective stroke of the press 1 or of another press, at least two further components are processed simultaneously by means of two further tools of the respective further tool set, so that, for example, the two further components form another combination in the same way as the components 8 and 9 form the combination 10.

[0051] In a second step S2 of the method, the first tools 6 and 7 and thus the first tool set 5 are configured and in particular subsequently produced as a function of the determined performance characteristic values, in particular by means of an electronic computing device.

[0052] The method described is based in particular on the following recognition and consideration: For example, the production of a component that is designed as a sheet metal component, for example, includes a plurality of process steps along or in a punching line, which is also referred to as a press line, for example, the component is for a vehicle and in particular for a body that is designed as a self-supporting body, for example, for a vehicle. For example, the original sheet metal blank is converted into the desired shape by reshaping and / or trimming the sheet metal blank. For this purpose, for example, the sheet metal blank is reshaped, in particular deep-drawn, profiled and / or trimmed and / or punched and / or perforated. Usually, component-specific tools, such as corresponding tools 6, 7, are used for each of these processes. A press line with a larger punching table, for example, provides the possibility of combining the production of multiple components in one tool set, as has been explained in the example of the press 1.

[0053] This combination of tools, such as tools 6 and 7, and then the combination of components, such as combination 10, may lead to a particularly favorable, especially high productivity of the press line, so this aspect should be carefully considered in the planning stage of new products. The combination of components, such as the combination 10 of components 8 and 9 or the combination of tools 6 and 7 is not a task that is easy to do. Therefore, for example, the mixing or combination of unfavorable materials, such as the combination of aluminum and steel, should be avoided, which may be particularly significant for reuse, and thus for the recycling of residues. The mixing of materials or raw materials or types of raw materials, with respect to residues caused by trimming operations (such as punching operations) and correspondingly remaining, may lead to a significant reduction in their value. In addition, the number of workflows of the combined components should be similar. In this regard, the content of the workflow should also be considered. If multiple slides are required, the available space on the punching table may be insufficient. On the other hand, it can be stacks of different heights (also referred to as blank stacks), which are used to manufacture various components and are formed, for example, by stacking blanks one above the other. Here, component 8 is, for example, one of the slabs of a slab stack, and component 9 is, for example, a slab of another slab stack. The robot arm that moves the corresponding slab or corresponding component 8, 9 to the press 1, in particular transports and in particular moves it, in particular transports it to the press 1, can usually pick up multiple slabs only when the current height difference between the heights of the stack is lower than a threshold value that depends on the machine. For the deep drawing process, additional aspects can be considered. Due to the contact of the clamp (Binder) (sheet clamp) of the affiliated stretching process with the unique stretching pad (also referred to as pad), the force (also referred to as sheet clamping force or clamping force) required for the sheet clamp (also referred to as clamp) of the clamping component (for example, component 8 and 9) during the stroke or in the stroke should be the same or similar. It is also advantageous to design the same stretching depth for all slabs to be stretched or components, such as components 8 and 9. In order to circumvent these restrictions or boundary conditions, a spring can be installed. In addition, the force application point of the pressure also plays an important role to avoid the tilting of the press slide. Advantageously, the generated force application point of the corresponding tool should be located at least in the vicinity of the intersection of the symmetry lines of the punching table of the press 1. The corresponding size of the corresponding blank (also referred to as blank) or the corresponding size of the corresponding components 8, 9 can influence the selection of the corresponding combination if necessary, because the available space on the punching table may be limited and machine-dependent, which may limit the maximum expansion of the corresponding tool (for example, configured as a drawing tool) and therefore also the expansion of the blank. The performance of the component combination (for example, combination 10) can be studied and / or evaluated based on performance characteristic numbers, such as the previously mentioned performance characteristic values, which are detected during production, thus during the execution of the corresponding manufacturing process. Such variables such as scrap volume, rework or productivity may be available in the database.When interpreting such characteristic numbers and in particular when comparing production processes, such as manufacturing processes, the similarity of the components should also be taken into account. Criteria for assessing the similarity of the components can be their size, material or raw material, the type of press line used for production, and the respective vehicle type for which the components 8 and 9 are manufactured or processed. The data for the similarity can be found, for example, in a database of the planning process.

[0054] The method enables the determination of suitable combinations for specific component types with other component types. In this regard, component types should be considered as a category, which includes components that are similar in terms of geometry and function from various products (e.g., automotive projects). In order to find possible combinations, for example, the content of a database can be used, which can contain solutions currently or in the future used in a stamping shop. In this regard, a favorable step is the definition of component categories. A category can be all the side bodies or side walls of vehicles (or the bodies of vehicles) that are currently produced or have been produced in the past. A possible solution is to derive categories based on component names. In general, it cannot be taken as a starting point that component names are standardized. This means that components or components with similar geometry and function may differ in their names. In order to circumvent or overcome this challenge, component name standardization can be achieved through rules and / or artificial intelligence (KI). Based on this standardization, categories of component names can be derived. Finally, for example, each unique component name represents a class of components. In particular, "component" should be understood as a component or the component. Based on a list that may contain standardized component names and component identification numbers, the content of the category can be calculated, that is, a list of component identification numbers for multiple vehicle items. The component identification number is the name of a component for a product such as a car, and is usually unique for all products of a company. In this regard, the term "combination type" is introduced, which describes a combination consisting of a type of components (also called components), such as combination 10. In addition, the term "manufactured combination" is defined, for example, which represents an instance of a combination type, which includes a list of component identification numbers. In addition, for example, for each combination of a specific component type that is made or manufactured, information from all available data sources in the process chain from planning to production is additionally queried in order to obtain hints for designing a new production process. Naturally, the information content is higher in the case of a production process with lower performance during production. Typically, a plurality of performance indicators are provided for the production process, such as scrap rate, rework share and / or productivity. All suitable indicators can be combined with the corresponding production combination, for example. In this way, for example, the production combination with the highest information content can be determined. By analyzing the distribution of the combined performance with respect to the available production combinations, the situation with the highest information content can be determined. For example, if only one of the combinations made has low performance, then that combination should contain the highest information content.

[0055] A process with good performance characteristics also has a high information content. This process can be used as a reference. An analysis of the combination types shows which combinations have been used so far. This allows for a more targeted study of the combination of components.

[0056] For example, if a company's products or components differ greatly from each other in their geometry and / or function, the constructor may be more inclined to focus on information about products similar to the manufactured combination. This introduced similarity can be extended to the conditions of the production process, such as the type of press line or stamping line or the individual characteristics of the component (such as raw materials and / or geometry). Therefore, a parameter indicating the order of the degree of consistency can be calculated to help the constructor find a reference combination. According to the performance indicators (performance characteristic values) introduced above, the manufactured combination with the highest similarity and the best performance obtains the highest grade. These combinations can be used as a reference for the conception of a new production process or the conception of a new tool (such as tools 6 and 7), and then the conception of tool set 5. In addition, other information can be added to the manufactured or processed combination, but this information has no effect on the order. An example may be the complexity of the combination. The so-called simple case can be a combination of two parts (components) that are geometrically connected by a symmetry plane. When multiple parts are combined without a geometric relationship between each other, the complexity increases. Multiple performance characteristic values ​​of a manufacturing process can be combined into a grade or grade value. Furthermore, it is conceivable to combine the performance characteristic value and the grade to form another grade or another grade value. Against this background, at least the following advantages can be achieved by the method:

[0057] An overview of all combinations of a component type that have been used or produced to date, in order to quickly and easily gain insights into the design of new production processes for the same component type.

[0058] -Enrich the overview by automatically providing statistics on different performance metrics and similarities from different data sources to recommend reference designs.

[0059] The method allows the identification of component combinations with the highest information content and, moreover, allows further analyses based on the determined component identifications in addition to the statistical data provided.

[0060] The method does not require excessive data analysis skills from personnel in the manufacturing process, such as planners and constructors.
