Description

Technical Field

[0001] The invention relates to a punching tool holder, a punching tool, a punching tool system, a punching machine and / or a method for producing a punched part and / or a method for setting a punching machine and / or a punching tool holder. Background Art

[0002] Punching tools and holding devices for said tools in punching machines are already known from the prior art. They are used to shape blanks by forming them by punching, in order to thereby produce components or semi-finished products. However, the problem with the systems or devices known from the prior art for holding punching tools is that their setting is very time-consuming and / or the preparation time is very high. Summary of the invention

[0003] It is therefore an object of the present invention to save time required by personnel for preparing or setting up a punching tool or a punching machine.

[0004] This object is achieved by means of a punching tool holder according to claim 1, by means of a punching tool according to claim 9, by means of a punching tool system according to claim 10, by means of a punching machine according to claim 11 and by means of a method for producing or for setting a punching machine according to claim 17. Further advantages, features and embodiments are found in the dependent claims, the description and the drawings.

[0005] According to the present invention, a punching tool holder is provided. The punching tool holder comprises a punching tool receiving portion and / or a primary tool adjustment device, in particular extending in the longitudinal direction, wherein the punching tool receiving portion is used for or can be used for receiving a punching tool, wherein the primary tool adjustment device has an X-direction adjustment device and a Y-direction adjustment device, wherein the X-direction adjustment device realizes or can realize a position change of the punching tool along the X-direction, wherein the Y-direction adjustment device realizes or can realize a position change of the punching tool along the Y-direction, wherein the X-direction adjustment device is independent of the Y-direction adjustment device, wherein the X-direction, the longitudinal direction and the Y-direction are respectively perpendicular to each other or can be respectively perpendicular to each other. The punching tool holder is used to accommodate the punching tool and support the punching tool relative to the substrate and / or the punching machine. The punching tool holder can be installed at the punching machine or constitute a part of the punching machine. Overall, the punching tool holder can therefore be or include a tool receiving portion. In order to reliably accommodate the punching tool, the punching tool holder has a punching tool receiving portion, and the punching tool receiving portion can in particular have a circular cross-section, in particular in a plane perpendicular to the longitudinal direction. The punching tool receiving portion is used to be able to introduce a punching tool or the punching tool into the punching tool receiving portion. Advantageously, here, the punching tool holder or the material of the punching tool holder completely surrounds the punching tool receiving portion in a plane perpendicular to the longitudinal direction. In other words, the punching tool receiving portion can be bounded by the punching tool holder or by the wrapping portion perpendicular to the longitudinal direction. The punching tool receiving portion extends in particular in the longitudinal direction. The longitudinal direction is in particular the direction in which the punching tool can be introduced into the punching tool receiving portion. Alternatively or additionally, preferably, in the end, the longitudinal direction can also be the direction in which the punching tool has its maximum main dimension along the direction and / or the workpiece is finally processed along the direction or the die moves relative to the female die in the final punching process along the direction. In addition to the punching tool receiving portion, the tool holder also has a primary tool adjustment device. The primary tool adjustment device has an X-direction adjustment device and a Y-direction adjustment device. The X-direction and the Y-direction can advantageously be perpendicular to each other and / or also perpendicular to the longitudinal direction respectively. In other words, the X-direction, the Y-direction and the longitudinal direction can form orthogonal coordinate systems to one another. The X-direction adjustment device is used or is configured such that, when there is a punching tool in a final or prescribed position within the punching tool holder, the X-direction adjustment device can achieve a position change of the punching tool along the X-direction. The prescribed position is in particular the position within the punching tool holder that the punching tool should and / or must occupy for the punching process. In the same way, the Y-direction adjustment device is configured such that it can achieve or can carry out a position change of the punching tool along the Y-direction.The position change should be understood in particular as that the tool or punching tool can be placed in a new position, which is different from the previous position or position of the tool in the punching tool holder, wherein the tool or punching tool can also be used for the punching process in the new position. In other words, the X-direction adjustment device and the Y-direction adjustment device can be used to change the position of the punching tool in the punching tool holder or in the punching tool holder, respectively. Thus, it can be finally achieved that the effects caused by the warping caused by wear, temperature and / or other undesirable position changes of the tool and / or other workpiece deviations from the desired production can be compensated and / or eliminated. The X-direction adjustment device and the Y-direction adjustment device are particularly independent of each other. Independence should be understood in particular as that when the position changes along the X direction, the required displacement along the Y direction and / or along the longitudinal direction or only due to the existing tolerance is performed. The same is true in the Y-direction adjustment device, which does not cause a position change along the X direction and / or along the longitudinal direction by its independence. In particular, the X-direction adjustment device may cause a change in the longitudinal direction, but does not cause a change in the Y direction. This can apply in the same way or alternatively to the Y-direction adjustment device. The independence of the X-direction adjustment device from the Y-direction adjustment device allows particularly fast and efficient setting, in particular after changing the punching tool.

[0006] Preferably, the X-direction adjustment device and / or the Y-direction adjustment device and / or the punching tool holder are configured so that they hold or are capable of holding the punching tool in the X-direction or the Y-direction. In other words, the X-direction adjustment device can be configured so that it can ultimately prevent the displacement of the punching tool relative to the punching tool holder and / or the punching tool receiving portion in the X-direction, especially by form fit and / or force fit. In the same way, the Y-direction adjustment device can also be configured so that it can prevent the position change of the punching tool relative to the punching tool holder and / or the punching tool receiving portion in the Y-direction, especially by form fit and / or force fit. Thereby, reliable positioning of the punching tool within the punching tool receiving portion can be achieved.

[0007] Preferably, the punching tool holder has a secondary adjustment device, wherein the secondary adjustment device has a longitudinal direction adjustment device, wherein the longitudinal direction adjustment device has an L operating device, wherein the L operating device causes or can cause the displacement of the punching tool in the longitudinal direction by displacement and / or by rotation around the L operating axis. In other words, the punching tool holder can also have a secondary adjustment device, wherein the secondary adjustment device has at least one longitudinal direction adjustment device, through which the punching tool, especially the punching tool accommodated in the punching tool receiving portion, can be displaced in the longitudinal direction relative to the punching tool holder and / or relative to the punching tool receiving portion. It should be understood that relative to the punching tool holder, in particular, the center of gravity of the punching tool holder can be changed relative to the center of gravity of the punching tool. The longitudinal direction adjustment device has an L operating device. The L operating device or, in principle, the operating device of the direction adjustment device is here the possibility of engagement and / or the possibility of action or the possibility of operation of the corresponding direction adjustment device. For example, such an operating device can be a hand wheel, a tool action possibility, in particular a screw head or an information port. The L-actuation device can be actuated here by displacement and / or by rotation about the L-actuation axis or the L-actuation axis. Advantageously, the longitudinal direction adjustment device of the punching tool can hold or hold the punching tool in the longitudinal direction.

[0008] Alternatively or additionally, the L operating device can preferably also have a servomotor for the operation.

[0009] Advantageously, the X-direction adjustment device has an X-operating device, wherein the X-operating device causes or can cause the displacement of the punching tool in the X-direction by displacement and / or by rotation around the X-operating axis. In other words, the X-direction adjustment device can have an operating device, which can be referred to as an X-operating device. The X-operating device is, for example, also designed as a form-fitting and / or force-fitting and / or information-based operating device. Advantageously, the operating device can be a screw head, a hexagonal portion, a hand wheel and / or a friction wheel and / or an information input end. When the X-operating device is operated in the form of displacement and / or rotation around the X-operating axis, the punching tool in the punching tool receiving portion can be displaced in the X-direction. In other words, for example, by the movement of the X-operating device in the direction of the X-operating axis and / or by the rotation of the X-operating device around the X-operating axis, the punching tool or the punching tool in the tool receiving portion can be displaced or moved in the X-direction. Thus, a particularly simple and compact operation or adjustment possibility of the punching tool within the punching tool holder can be achieved.

[0010] Alternatively or additionally, the X-direction adjustment device can preferably also have a servomotor for operation.

[0011] Advantageously, the Y-direction adjustment device has a Y-operating device, wherein the Y-operating device causes or can cause the displacement of the punching tool along the Y-direction by displacement and / or by rotation around the Y-operating axis. The Y-direction adjustment device can be configured in a similar manner to the X-direction adjustment device and / or the longitudinal direction adjustment device, wherein the X-direction adjustment device is configured in a similar manner to the longitudinal direction adjustment device and / or the Y-direction adjustment device. In other words, the features explained above with respect to the longitudinal direction adjustment device and / or the X-direction adjustment device can also be used in principle for the longitudinal direction adjustment device, the X-direction adjustment device and / or the Y-direction adjustment device. In other words, therefore, for example, the Y-direction adjustment device can have a Y-operating device that is also in the form of a friction wheel and / or a screw head or a hexagonal portion. Overall, therefore, the features described above can be arranged in the X-direction adjustment device, the Y-direction adjustment device and / or the longitudinal direction adjustment device, regardless of whether they have been disclosed for the X-direction adjustment device, the Y-direction adjustment device and / or the longitudinal direction adjustment device.

[0012] Preferably, the X operating axis and the Y operating axis are parallel to each other. Alternatively, preferably, the X operating axis and the Y operating axis can also be at least substantially parallel to each other. At least substantially parallel should be understood here as the angle enclosed between the two axes being a maximum of 10°, preferably a maximum of 5°, particularly preferably a maximum of 1° and particularly preferably a maximum of 0.5°. The X operating axis and the Y operating axis can be oriented in particular parallel to the X direction or the Y direction. It is particularly preferred that the longitudinal operating axis, which can also be referred to as the L operating axis, is also oriented parallel to the X operating axis and / or the Y operating axis. By means of the described orientation of the operating axes, in particular the X operating axis parallel to the Y operating axis, a particularly simple setting possibility of the operating axes can be achieved, in particular, for example, the robot head does not have to be reoriented, so that valuable time can be saved when setting the punching tool or the punching tool system.

[0013] Particularly preferably, the X-axis and the Y-axis are parallel to the L-axis. As a result, the setting of the robot system can also be further simplified and shortened or accelerated.

[0014] Preferably, the X-axis and the Y-axis are oriented perpendicular to the longitudinal direction, in particular, the direction is oriented parallel to a vertical or horizontal line. In other words, the X-axis and the Y-axis can be perpendicular to the longitudinal direction, respectively. Advantageously, the X-axis and / or the Y-axis can extend vertically and / or horizontally. As a result, the accessibility of the X-axis and / or the Y-axis can be improved. Therefore, by means of the measures described, the operation of the elements of the primary tool adjustment device can also be realized more simply, so that, in particular when used with the aid of a correspondent, setting time and thus also preparation time can be saved.

[0015] Advantageously, the primary tool adjustment device has a screw, wherein the screw can constitute or be part of the X-direction adjustment device and / or the Y-direction adjustment device. Particularly preferably, the X-direction adjustment device and the Y-direction adjustment device can each have a screw. By using a screw, in particular a self-fixing screw, a particularly precise setting of the X-direction adjustment device and / or the Y-direction adjustment device can be achieved. For example, the screw can be a ball screw and / or form a setting system together with a ball screw nut. In other words, the X-direction adjustment device and / or the Y-direction adjustment device also have a ball nut. Alternatively or additionally, preferably, the screw can also have a trapezoidal thread.

[0016] Advantageously, the primary tool adjustment device has a form-fitting movement device, wherein the form-fitting movement device constitutes or can constitute a part of the X-direction adjustment device and / or the Y-direction adjustment device. A form-fitting movement device is to be understood here as a movement of the punching tool that can be caused by form fit. For example, such a form-fitting movement device can be an inclined plane. Advantageously, the inclined plane is in the XY plane with its inclination. For example, the inclined plane can be configured so that when the inclined plane is displaced in the X direction, a movement in the Y direction is caused.

[0017] Advantageously, the secondary tool adjustment device has a screw, preferably two screws, wherein one screw or the plurality of screws form part of the longitudinal direction adjustment device. Advantageously, in the case of two screws, the two screws are oriented parallel to one another. By providing a screw in the direction adjustment device, in particular in the longitudinal direction adjustment device, a particularly high adjustment possibility can be achieved, wherein at the same time, however, a high precision can be achieved. Advantageously, the screw of the secondary tool adjustment device can have the same features as the screw of the primary tool adjustment device and vice versa.

[0018] Advantageously, the punching tool holder has an ID, in particular an RFID chip, and / or the punching tool holder has an ID reading device, in particular an RFID reader. By providing an RFID chip and / or other IDs, in particular a barcode, a color code and / or an identification number at the punching tool holder, the punching tool holder can be identified one-to-one. Thus, for example, screw gaps or other setting possibilities that occur in the punching tool holder have been compensated by presetting when they are known. The situation ultimately also leads to a faster setting of the punching tool within the punching tool holder. In addition or alternatively, the punching tool holder can also have an RFID chip reader or an RFID reader, whereby the punching tool holder automatically provides information, which can be realized, for example, that the punching tool has been identified one-to-one when it is installed. The situation can also cause, for example, that the setting of the primary tool adjustment device and / or the secondary tool adjustment device can be carried out depending on the tool. Therefore, setting time can also be saved thereby.

[0019] Advantageously, the punching tool holder has a display system and / or an information providing unit, wherein the display system and / or the information providing unit is designed so that it (the display system and / or the information providing unit) displays or provides the following information: in which setting the primary tool adjustment device, in particular the X-direction adjustment device and / or the Y-direction adjustment device, and / or the secondary tool adjustment device is. The display system can be, for example, a digital display unit and / or a readout scale. The information providing unit can be, for example, a cable and / or wireless information processing unit, which provides information related to the setting of the primary tool adjustment device and / or the secondary tool adjustment device. By notifying the setting of the primary tool adjustment device and / or the secondary tool adjustment device by means of the display system and / or by means of the information providing unit, it is possible to read in a simple manner in which position and / or setting the primary tool adjustment device and / or the secondary tool adjustment device is in order to use the information, for example, to re-initiate the same setting at a later time. In particular, when the information displayed and / or provided is stored in association with the punching tool present in the punching tool holder, this setting can be reproduced in a simple manner later, so that when refitting and / or resetting the punching tool and / or the punching tool system, a new production readiness can be established in a rapid manner. Thus, the punching tool and / or the punching machine can be quickly refitted and / or set up by the display system and / or the information provision unit.

[0020] Another aspect of the present invention can relate to a punching tool. Advantageously, the punching tool has an ID, in particular an RFID chip. In principle, the ID allows the identification of an element on which or at which the ID is provided. The ID can be a barcode, a color code, an RFID chip, a one-to-one identification number, a serial code or other identification element. By providing the ID at the punching tool, the punching tool can be identified one-to-one. By identifying the punching tool, for example, by an RFID chip reading device or reader, the punching tool can be identified, and in particular, according to the stored settings for the primary tool adjustment device and / or the secondary tool adjustment device - according to the information read out for the one-to-one identified punching tool - and by the stored settings of the primary tool adjustment device and / or the secondary tool adjustment device, setting time can be saved. Advantageously, by means of the tool used, setting variables, in particular manufacturing deviations at the tool (which have been measured in advance) can be compensated by the primary tool adjustment device and / or the secondary tool adjustment device.

[0021] Another aspect of the invention can relate to a stamping tool system. Advantageously, the stamping tool system comprises a stamping tool holder, in particular as described above and / or hereinafter, and a stamping tool, in particular also as described above and / or hereinafter.

The present invention can therefore relate to a stamping tool system, wherein the stamping tool is a die or the stamping tool system can comprise a stamping tool, which is a die. The die is characterized in particular in that it performs a translational and / or rotational movement during the forming process. The die is characterized in particular in that it can be stationary during the stamping process, in particular stationary relative to a base of the punching machine.

[0022] Another aspect of the invention can relate to a punching machine. Advantageously, the punching machine can relate to a punching tool holder, in particular as described above and / or below, and / or a punching tool system, in particular as described above and / or below.

[0023] Advantageously, a stamping machine, in particular as described above and / or below, can include a robot system, wherein the robot system has an operating unit for a primary tool adjustment device and / or a secondary tool adjustment device for a stamping tool holder, in particular a stamping tool holder of a stamping machine, and / or wherein the robot system has a gripping unit for a stamping tool. In other words, the present invention can in principle relate to a stamping machine with a robot system. In the case where a stamping machine includes a robot system, it should be understood in particular that the robot system interacts and / or can interact with individual structural elements present at and / or in the stamping machine. Particularly preferably, however, the robot system is mounted on a base of the stamping machine, in particular a stamping machine. The robot system can have a primary tool adjustment device and / or a secondary tool adjustment device for a stamping tool holder of a stamping machine, in particular an operating unit for a primary or secondary adjustment device. The operating unit is used to cause the setting of the primary tool adjustment device and / or the secondary tool adjustment device, and thus in particular the setting of the X-direction adjustment device and / or the Y-direction adjustment device and / or the longitudinal direction adjustment device. It is thus particularly feasible that the setting of the primary tool adjustment device and / or the secondary tool adjustment device can be caused by automatic engagement. The operating unit can have an operating motor, by means of which the X-direction adjustment device and / or the Y-direction adjustment device and / or the longitudinal direction adjustment device can be operated respectively. Alternatively, preferably, the operating unit can be operated via operating motors for the X-direction adjustment device and / or the Y-direction adjustment device and / or the longitudinal direction adjustment device respectively. In other words, for example, a motor can be provided for the X-direction adjustment device and / or the Y-direction adjustment device, and another motor of the operating unit can be provided for the longitudinal direction adjustment device. The operating unit can in particular be a screw unit. Alternatively, preferably, the operating unit can also be and / or include a servo unit. In addition, alternatively or additionally, preferably, the robot system can also have a gripping unit for the punching tool. It is thus particularly feasible that the robot system can remove and / or introduce a punching tool from a punching machine. Advantageously, the punching machine and / or the robot system has a storage device for an operating unit and / or for a gripping unit and / or other robot system accessories. In other words, the robot system can therefore use the storage unit or storage system in order to temporarily store and / or store an operating unit of the robot system and / or a gripping unit of the robot system. The storage system can also be referred to as a reservoir. By providing a robot system, the setting of the primary tool adjustment device and / or the secondary tool adjustment device and the rapid replacement and / or removal or introduction of the punching tool into the punching machine, in particular the punching tool holding device of the punching machine, can be carried out in a particularly simple and fast manner.

[0024] A punching tool, in particular as described above or below, and / or a punching machine, in particular as described above or below, is set using a punching tool holder, in particular as described above or below, and / or a punching tool system, in particular as described above or below.

[0025] Another aspect of the present invention can relate to a punching machine, in particular as described above and / or below. Advantageously, the punching machine has a screw, in which the ID of the punching tool and / or the punching tool holder and / or the settings for the primary tool adjustment device, in particular for the X-direction adjustment device and / or the Y-direction adjustment device and / or for the secondary tool adjustment device are stored or can be stored in a memory. In other words, the punching machine can have a memory or alternatively the punching machine can access a memory, in which specific settings for the primary tool adjustment device and / or for the secondary tool adjustment device are stored for the punching tool respectively. In other words, in the memory, the association between the settings of the primary tool adjustment device or the secondary tool adjustment device and the punching tool and / or the punching tool holder can be stored. In particular, the information provided by the display system and / or the information providing unit of the punching tool holder can be saved in the memory. By setting a one-to-one association with the punching tool and / or the punching tool holder, the setting of the primary tool setting and / or the secondary tool setting can be achieved in a particularly efficient manner. The setting can in turn be carried out efficiently by the robot system, in particular by an operating unit of the robot system, advantageously automatically, and therefore in particular without the intervention of an operator.

[0026] On the other hand, it can also involve a stamping machine, in particular as described above and / or below, in which the stamping machine, in particular the robot system, has an ID reading device, in particular an RFID chip reader. Alternatively, preferably, the stamping tool holder can also have an ID reading device. Thereby, a particularly fast and efficient possibility of determining an ID, in particular an ID of a stamping tool, is achieved. The ID reading device can be a visual reading device, in particular a barcode reader and / or a camera, for example. Advantageously, the ID reading device can be connected to a memory, in particular to a memory / memory as described above for the machine tool. The relationship between the found ID and the settings for the primary tool adjustment device and / or for the secondary tool adjustment device can be saved in the memory.

[0027] Advantageously, the present invention can relate to a punching machine as described above and / or below, wherein the punching machine has a measuring device and / or an input device, in particular for measuring data of the manufactured workpiece. The punching machine can therefore have a device, in particular a measuring device and / or an input device for measuring data, wherein the measuring device can in particular measure the manufactured workpiece with respect to a predefined size or a determinable size. In particular, the measuring device can be arranged in the ejection area or ejection portion of the punching machine, which can also be referred to as a machine tool in the scope of this application. Alternatively or additionally, preferably, the measuring device can also be supplied by a robot system. In other words, the robot system can also convey the workpiece to be measured to the measuring device. The measuring device can be a contactless measuring device, in particular a laser, a capacitive and / or inductive proximity switch and / or a grating and / or a camera. And the input device can be, for example, a key or a numeric keypad. By transmitting measured values ​​or measurement data that can be read in by the measuring device and / or by inputting the measurement data into the machine tool, in particular of the workpiece being manufactured, it can ultimately be determined how settings, in particular settings of the primary tool adjustment device and / or the secondary tool adjustment device, should be made in relation to the ascertained measurement data. In particular, the input device can be part of the robot system. In particular, however, the robot system is connected (informatically) to the measuring device and / or to the input device, wherein in the end (informatically) a control unit can be placed between the robot system and the measuring device or the input device. The control unit can in particular determine deviations from expected values ​​and transmit setting information to the robot system as a function of the deviation and / or determine setting information for the primary tool adjustment device and / or for the secondary tool adjustment device.

[0028] Another aspect of the present invention can relate to a stamping machine, in particular as described above and / or below, in which the robot system is designed to set the primary tool adjustment device and / or the secondary tool adjustment device according to data input into the input device and / or based on data detected by the measuring device. Alternatively, preferably, the robot system can also or additionally be configured to set the primary tool adjustment device and / or the secondary tool adjustment device according to deviations of the data input into the input device and / or based on deviations of the data detected by the measuring device (from the expected data set). In other words, the robot system can be used to perform the setting of the primary tool adjustment device and / or the secondary tool adjustment device based on the detected data and / or the input data and / or based on the deviation of the input data from the expected data set and / or based on the deviation of the data detected by the measuring device from the expected data set. In particular, for this purpose, the robot system and / or the stamping machine can have a control device, wherein the control device can be the control unit detailed above or can include the control unit. In other words, it is thereby possible, in particular, that the primary tool adjustment, in particular the X-direction adjustment and / or the Y-direction adjustment and / or the secondary tool adjustment, can be set due to manufacturing deviations and / or due to specifically input values. It is thereby possible, in particular, to establish a closed control loop and / or to enable control of the setting system by specifically inputting data. With these two possibilities, in particular with a “closed” control loop, a particularly time-saving setting and / or preparation of the punching machine can thus be achieved.

[0029] Another aspect of the invention can relate to a punching machine, in particular as described above and / or below, wherein the punching machine is a multi-stage press. In particular, the multiple stages of the press can be arranged in the X direction and / or in the Y direction. By configuring the punching machine as a multi-stage press, a large degree of forming can be achieved in particular quickly and efficiently.

[0030] Another aspect of the present invention can likewise relate to a stamping machine, in particular as described above and / or below, wherein each stamping level of the stamping machine, in particular a multi-stage stamping machine, has a stamping tool holder, in particular as described above and / or below, and / or wherein each stamping level, in particular each stamping level of a multi-stage press, can be set by a robot system. As a result, particularly high savings in setting time can be achieved. The settability of the robot system relates in particular to a primary tool adjustment device and / or a secondary tool adjustment device for each stamping tool holder. In particular, here, a stamping tool holder having a stamping tool in the form of a die and / or a stamping tool holder having a stamping tool in the form of a die can be set by a robot system.

[0031] Another aspect of the invention can relate to a method for producing a stamped part and / or a method for setting a stamping machine, in particular using a stamping tool holder as described above and / or below and / or a stamping machine as described above and / or below and / or a stamping tool system as described above and / or below. Alternatively, the invention can also relate to a method for setting a stamping tool holder and / or a stamping tool system. All these methods comprise in particular the following steps:

[0032] a) providing a shaped blank;

[0033] b) forming the shaped blank into a shaped part, in particular by means of a punching tool, advantageously such as the punching tool described above and below;

[0034] c) measuring the molded part, in particular by means of a measuring device for a punching machine;

[0035] d) Setting the punching machine, in particular by means of a primary tool adjustment, in particular an X-direction adjustment and / or a Y-direction adjustment, and / or a secondary tool adjustment, in particular to minimize deviations of the future molded part from a desired geometry.

[0036] The method is therefore used to define the deviation produced by the forming of the shaped blank to a desired amount, in particular by measuring the shaped part, wherein the stamping machine and / or the stamping tool holder are set according to the measurement, in particular according to the deviation of the measurement from the desired geometry. The setting is particularly carried out so that the deviation from the desired geometry is reduced. The setting can be carried out by a robot system and / or manually, for example. Finally, during the setting, the primary tool adjustment device and / or the secondary tool adjustment device can be operated so that the position of the stamping tool can be changed relative to the stamping tool holder or relative to the stamping machine in the Y direction, in the X direction and / or in the longitudinal direction. Thereby, in particular, an open control loop can be realized and / or the beginning of a closed control loop can be constructed.

[0037] A refinement of the method can in particular comprise the step of repeating steps b) to d or a) to d) until the deviation from the desired geometry of the molded part or of the molded part re-manufactured by undergoing steps b) to d) or a) to d) respectively, falls below a defined threshold value. The deviation from the desired geometry can in particular relate to the deviation of the individual values ​​and / or the average value of the different values. By continuously continuing steps b) to d) or even steps a) to d), a closed control loop can in particular be realized, so that the final setting is thus finally reached automatically and / or semi-automatically, and therefore only with a small amount of operation or operator intervention. In particular, the method can also be realized here in such a way that the method is used during a mass production cycle, so that the deviation from the desired amount occurring during the mass production of molded parts can be reduced by setting the punching machine or by setting one or more punching tool holders. Advantageously, the setting is performed by a robot system, as already explained, so that a particularly high degree of injury protection can thereby be provided. BRIEF DESCRIPTION OF THE DRAWINGS
