Description

The invention relates to a device for machining at least one workpiece, which has at least one machining unit having a frame with a frame top and a frame base which are relatively movable to each other, wherein the upper frame part a module top and the lower frame part a module lower part of a processing module are arranged.

Such a device is known from DE 20 2014 004 374 U1 the applicant known. The processing unit for a punch press described in this publication has a frame top, to which a module top can be fastened is, and a frame base on which a module base is fastened, on. The frame top part and thus the module top part fastened to it and the frame bottom part together with the module bottom part attached to it are brought into relative motion by a drive device. For this purpose, the frame upper part is arranged on an upper receiving plate of the frame and the lower frame part on a lower receiving plate of this frame. The aforementioned drive mechanism of the device causes one or both receiving plates along their guide columns perform a lifting movement, whereby the relative movement between the frame top and the frame base and thus between the module top and the module base is achieved. As a rule, the upper receiving plate and thus the frame upper part connected thereto together with the upper module part are moved up and down with a stationary lower receiving plate. In order to align the frame upper part to the frame base, a guide column is provided in the known device and for aligning the module upper part or the module lower part, a further guide column is provided, which serves to guide these two module parts.

Efficient mass production of such stamped parts requires more and more frequently that in addition to the first punching step, which usually removes the stamped part from the stamped material, further processing steps, in particular stamping steps, are performed on a workpiece by means of such devices. The replacement of a processing unit of the known punching press against a differently configured module for carrying out the further processing operation is impossible since the module upper part and the module lower part of the processing module of the processing unit formed in this way must be precisely aligned with one another for precise production of such punched parts in order to achieve the required accuracy , In addition, the punching material and / or the stamped part and the machining module must be exactly aligned to each other in order to achieve the required precision in the machining process. In general, therefore, the punched parts manufactured in one device must be transported to another device to there the further processing operation to carry out. Even then, a positionally accurate alignment of the stamped part to the tools of the machining module is required.

In the frame upper part and in the frame lower part of the frame of the processing unit, devices such as pressure elements, holders, etc., which are module-specific, are respectively provided in a manner known per se. The replacement of a module upper part and / or a module lower part of the processing module against another such module part is therefore not practical, since for a precise function of the processing unit, the frame base and the module base and the frame top and the module base must be coordinated. If, therefore, a different processing operation is to be carried out with a processing device, the frame must therefore as a rule be adapted to the processing module.

It is therefore an object of the present invention, a processing device of the type mentioned in such a way that the implementation of at least two machining operations on a workpiece is made possible in a simple manner.

This object is achieved by a processing device having the features of claim 1.

Such a measure has the advantage that this simplifies the insertion and / or replacement of processing units.

A further advantageous development of the invention provides that in at least one processing unit of the processing device according to the invention, the processing module is arranged interchangeable in the frame. Such a measure has the advantage that an exchange of the machining module is made possible without the entire machining unit having to be removed from the machining device according to the invention.

A further advantageous development of the invention provides that the processing device has at least one centering adapter, by which the frame top and the frame base of the frame or one of the processing units are aligned to each other, preferably provided according to a further advantageous embodiment of the invention that in the frame base at least one processing unit, a first centering unit with a first centering and in the Gestelloberteil a third centering unit is arranged with a centering, and that the centering adapter has a second centering unit with two centering, wherein during the centering of the frame, the centering of the first centering with the first centering of the second Centering and the second centering this Centering unit cooperates with the centering of the third centering unit. This measure, which also has an independent patent-establishing character, causes, in a particularly simple manner, the frame top and the frame base are precisely aligned with each other.

A further advantageous development of the invention provides that at least one processing unit of the processing device has at least one module centering device for aligning the processing module with the frame of this processing unit, wherein it is preferably provided that a centering element is provided in the module top part of the processing module and / or in its module bottom part is, which cooperates with provided in the frame upper part and / or in the frame base of the processing unit centering of the centering device.

In the FIGS. 1 to 4 is a generally designated 1 embodiment of a processing device shown, which four of the below-described Processing units 10a-10d has. These are arranged between an upper base frame 2 a and a lower base frame 2 b of the processing device 1. It will be apparent to those skilled in the art from the following description that said number of four processing units 10a-10d is merely exemplary in nature. Depending on the processing operations to be performed by the processing apparatus 1, more or fewer processing units 10a-10d may be provided.

However, before the detailed structure and the function of the processing device 1 is described in more detail, an explanation of the basic structure and the function of one of the processing units 10a-10d, here the processing unit 10a, should be preceded for better understanding of this description. The further processing units 10b-10d are preferably identical in terms of their structure and function to the basic structure of the processing unit 10a, but this is not mandatory. As will be apparent from the following description, the "internal" structure of the individual processing units 10a-10d of the processing apparatus 1 is only of secondary importance. The individual processing units 10a-10d of the processing device 1 can thus be cutting or non-cutting processing units. The processing units 10a-10d may be, for example, cutting, stamping, embossing or bending processing units. It is also possible to form these processing units 10a-10d as forming units, for example for deep drawing. It is also possible to use one or more of the processing units 10a-10d of the processing device 1 for connecting workpieces or materials. A combination of the aforementioned processing units 10a-10d in the processing device 1 is possible. It is also possible that one or more processing units 10a-10d are designed as combination processing units such that more than one processing operation can be performed with them. In the FIG. 1 is assumed from the constellation that each of the processing units 10a-10d of the processing apparatus 1 - seen in the feed direction of a workpiece, the in FIG. 1 from left to right or from right to left - have the same extent. This too is not mandatory; the described processing device 1 allows advantageously also different lengths processing units 10a-10d between the upper base frame 2a and the lower base frame 2b, so in the processing device 1, to order. The above explanations show the high flexibility of the described processing device 1.

The FIG. 2 now shows a side view of the processing device 1 according to the arrow II of FIG. 1 , Between the upper base frame 2a and the lower base frame 2b of the processing device 1 - these two components will be described in more detail below - is a known per se and therefore only their basic structure explained after processing unit 10a. Their structure is in detail in the aforementioned DE 20 2014 004 374 U1 as well as the DE 10 2014 007 732 A1 The applicant described so that reference is made to avoid repetition of the two aforementioned publications and their disclosure by this reference to the subject of this application.

This processing unit 10a is in turn divided into a frame 11 which has a frame upper part 11a and a frame lower part 11b, and a processing module 12 with a module upper part 12a and a module lower part 12b. In the embodiment described here, the frame top part 11a has an upper clamping plate 11a 'and an upper frame plate 11a "and the lower frame part 11b has a lower clamping plate 11b', a lower frame plate 11b" and a lower pressure plate 11b "'. The detailed structure of such a frame upper part 11a and a frame lower part 11b are known; it is also not necessary for the understanding of the further description of the processing device 1, so that a detailed explanation of the structure and the operation of the Gestelloberteils 11a and the lower frame 11b of the frame 1 of the processing unit 10a can be dispensed with.

The processing module 12 is preferably arranged interchangeably in the frame 11 by the module upper part 12a on the frame top 11a and the module base 12b on the frame base 11b - preferably replaceable - are attached. The module upper part 12a has, in a known manner, a pressure plate 13a, which, preferably interchangeable, is fastened to the frame top part 11a. Under the pressure plate 13a, a holding plate 13b is arranged, which follows a cover plate 13c. At this a guide plate 13d is attached. The module lower part 12b is - also preferably replaceable - attached to the frame base 11b and has a cutting plate 14a, which is arranged on a lower pressure plate 14b.

The upper frame part 11a is in the embodiment described here via the upper platen 11a 'exchangeably connected to the upper base 2a of the processing device 1 and the lower frame 11b of the processing unit 10a on the lower platen 11b' to the lower second base 2b of the processing device 1 interchangeably connected. This can be done eg in FIG. 2 only schematically shown fastening means 11c and 11c ', for example, screw connections can be achieved, via which the frame top 11a on the upper first base frame 2a and the frame base 11b with the lower second base frame 2b of the processing device 1 are detachably connected. However, the use of a screw is not mandatory, but a plurality of fasteners 11c and 11c 'for the attachment of the Gestelloberteils 11a on the first base 2a and the frame base 11b are used on the second base frame 2b of the processing device.

How now from the FIG. 1 As can be seen, the upper base frame 2a and the lower base frame 2b of the processing apparatus 1 extend over all the processing units 10a-10d. The upper base frame 2a and the lower base frame 2b thus each form a continuous component of the processing device 1. However, it is not mandatory that both base frames 2 a and 2 b are designed in this way are. If, as discussed below, only one of the two base frames 2a and / or 2b moves during the machining process, it is sufficient that only the moved base frame 2a or 2b is designed to be continuous.

As can be seen from the figures, the two base frames 2 a, 2 b are connected to one another via guide columns 3 a and 3 b, so that the two base frames 2 a and 2 b are arranged relative to one another in the processing apparatus 1. To carry out this relative movement, the processing device 1 has a known per se and therefore not shown in the figures drive device such as a press with a press base and a press upper part, through which a lifting movement of the upper base frame 2a and / or the lower base frame 2b feasible is. As a rule, such processing devices 1 are operated in such a way that the upper base frame 2a and thus the module upper parts 12a connected to it via the frame upper part 11a of the processing units 10a-10d perform a lifting movement while the lower second base frame 2b and thus the module lower parts 12b of the processing units Resting 10a-10d. But it is also possible that the lower base frame 2 b performs a lifting movement, while the upper first base frame 2 a is stationary. A combination of these measures, namely that both the upper base frame 2a and the lower base frame 2b move, is possible.

By now providing that the upper base frame 2a and the lower base frame 2b receive all processing units 10a-10d of the processing apparatus 1 participating in the respective processing process, a synchronous lifting movement of the processing units 10a-10d is achieved. By a successive onward transport of or in the processing device 1 to be machined workpieces through these successively through the processing units 10a-10d, so that by means of the described processing device 1 in an advantageous manner to the same workpiece in a single Clamping several processing steps can be performed. The previously required in processing devices, each having only a single processing station, transport of the workpiece from one to the other processing device and a respective reorientation thus eliminated, so that the described processing device 1 is characterized not only by a high manufacturing precision, but also by high clock rates.

It is advantageous that at least one and preferably all processing units 10a-10d are exchangeably received in the processing device 1. Such a measure has the advantage that, as a result, the processing device 1 can be adapted to a wide variety of processing processes, by exchanging one or more processing units 10a-10d in each case.

In the embodiment shown, it is assumed that the length of the upper base frame 2 a and lower base frame 2 b of the processing device 1 is so large that all processing units 10 a - 10 d can be accommodated therein. Although it is also possible to choose the length of the base frames 2a, 2b, ie their extent in the transport direction of the processing device 1, larger and thus to make room for further processing units 10a-10d. Such a measure makes it possible in an advantageous manner that further processing units 10a-10d can be received in the processing device 1. This is advantageous, for example, if further machining units are required for a certain overall machining process apart from the machining units 10a-10d already present in the machining device 1. These can then simply be added to the already existing processing units 10a-10d.

As already mentioned, the production of precision parts requires a positionally accurate alignment of the module parts 12a, 12b of the processing module 12 as well as the frame parts 11a, 11b of the frame receiving these module parts 12a, 12b 11 of the processing units 10a-10d. In the DE 20 2014 004 374 U1 the applicant is an advantageous procedure for aligning two cooperating frame parts 11a, 11b and in the DE 10 2014 007 732 A1 the centering of two module parts 12a, 12b relative to each other described in detail, so that reference is again made to avoid repetition of the aforementioned publications.

The following description therefore deals primarily with how the individual processing units 10a-10d are aligned in the processing apparatus 1 and shows a particularly advantageous way of doing so:

The FIG. 3 now shows a top view and the FIG. 4 a side view of the lower portion of the processing apparatus 1 according to the line III-III of FIG. 1 , It can be seen the upper surfaces of the frame bases 11b of the individual processing units 10a-10d, in the embodiment described herein, the surfaces of the lower pressure plates 11b '''and the surfaces of the arranged underneath the lower frame plates 11b "of the frame bases 11b of the individual processing units 10a-10d Frame sub-parts 11b are - as already described above - replaceably arranged in the processing device 1. Die vorgenannte FIG. 3 also shows schematically the extending between the upper base frame 2a and the lower base frame 2b guide columns 3a, 3b.

Each frame lower part 11b has one or more centering devices 20 - in the case shown here two such centering devices 20 'and 20 "- each having a centering element 20a which cooperates with a complementary centering element 20b of the frame lower part 11b of the adjacent processing unit 10a-10d. In the exemplary embodiment described, the centering elements 20a of the centering devices 20 'and 20 "of the lower frame part 11b of the first processing unit 10a thus interact with the complementary centering elements 20b of the lower frame part 11b of the second processing unit 10b together. The centering elements 20a arranged opposite to the second centering elements 20b of the centering devices 20 'and 20 "in the frame lower part 11b of the second processing unit 10b cooperate with the corresponding centering elements 20b of the frame bottom part 11b of the third processing unit 11c. The same applies to the frame bottom part 11b of the third processing unit 10c Embodiments of centering elements 20a, 20b, which together form a centering device 20 for two adjacent frame lower parts 11b of adjacent processing units 10a-10d, are located in the frame members 11b of the fourth processing unit 10d Figures 5 and 6 and will be described below.

Preferably, each second frame lower part 11b of each processing unit 10a-10d has a fixing element 22a of a fixing device 22 which cooperates with a complementary fixing element 22b of the second frame lower part 11b of the adjacent processing unit 10b-10d and which respectively together hold the fixing device 22 for two adjacent processing units 10a, 10b and 10b, 10c and 10c, 10d form. Embodiments of such a fixing device 22 are also in the Figures 5 and 6 shown.

The FIGS. 5a and 5b show the detail A1 of the FIG. 1 That is to say, the centering device 20 'and the centering devices 20, 20', 20 "acting between the further frame lower parts 11b of the further processing units 10b-10d are correspondingly built up.

As can be seen from these figures, in the embodiment described here in the lower pressure plate 11b '''arranged first centering 20a of the centering device 20 "of the frame base 11b of the processing unit 10a, a semi-circular recess 21 and the complementary centering element 20b of the centering device 20 "acting between two adjacent frame lower parts 11b of two adjacent processing units 10a, 10b has a further semicircular recess 21 'The recesses 21, 21' of the two centering elements 20a, 20b arranged in the lower pressure plates 11b '" are used in each case Receiving a centering pin 20c, the in FIG. 5b is shown in section. The outer contour of the centering pin 20c is in this case matched to the contour of the recesses 21, 21 'of the centering elements 20a, 20b, that the centering pin 20c only in a positionally accurate alignment of adjacent frame bottoms 11b adjacent processing units 10a, 10b and 10b, 10c and 10c , 10d can be pushed into the centering elements 20a, 20b of a centering device 20, 20 ', 20 "The semicircular shape of the recesses 21, 21' of the two centering elements 20a, 20b of the centering device 20, 20 ', 20" not only has the advantage in that such contours are to be produced with high precision. Rather, such a shape causes the two centering elements 20a and 20b and thus the centering device 20, 20 ', 20 "to enable a two-dimensional alignment of the frame lower parts 11b of adjacent processing units 10a, 10b, 10b, 10c, etc. The centering process will be described in more detail below.

In the FIGS. 5c and 5d is now an embodiment of a between two adjacent in the processing device 1 frame lower parts 11b fixing 22 according to the detail of the B1 FIG. 1 shown. The first fixing element 22a has a recess 23 and the complementary fixing element 22b of the frame lower part 11b of the adjacent machining unit 10b has a recess 23 '. In these two recesses 23, 23 'is a retaining clip 23 "can be used, which causes the cohesion of adjacent frame bases 11b adjacent processing units 10a-10d.

The alignment of the frame bases 11b of the processing units 10a-10d in the processing device 1 is now as follows, it being noted that the procedure described has only exemplary character: First, the frame base 11b of the first processing unit 10a inserted into the processing device 1 and locked in this position precisely by the frame base 11b by means of corresponding fasteners 13c ', z. As screws, in a defined position on the lower base frame 2 b of the processing device 1 is determined. Then, the lower frame part 11b of the second processing unit 10b is placed on the lower base frame 2b of the processing apparatus 1 and displaced until cooperating centering elements 20a, 20b of the centering devices 20 'and 20 "are aligned such that the centering pin 20c is inserted respectively into the two semicircular recesses 21 , 21 'of the centering elements 20a, 20b of the centering devices 20' and 20 "can be inserted. As a result, an exact positional relationship between the frame base 11b of the first processing unit 10a and that of the second processing unit 10b is achieved. In order to fix the two lower frame parts 11b of the two adjacent processing units 10a, 10b, the retaining clip 23 "is then inserted into the recesses 23 and 23 'of the fixing device 22 and the two frame bases 11b are fixed relative to one another The frame base 11b of the second processing unit 10b is fastened to the lower base frame 2b. The alignment of the frame base 11b of the third processing unit 10c with the frame base 11b of the second processing unit 10b takes place as described above, as well as the alignment of the further frame bases 11b relative to the respectively adjacent frame base 11b.

It will be apparent to those skilled in the art from the above description that the use of the fixators 22 is not mandatory. Rather, it is also possible, after aligning adjacent frame bases 11b to each other to attach them to the lower base frame 2b of the processing device 1, without that they are previously fixed in position to each other by the centering devices 22. However, the use of centering devices 22 facilitates the positionally accurate fastening of the frame bases 11b to the lower base frame 2b of the processing device 1.

Thereafter, the frame top portions 11a of the processing units 10a-10d are inserted into the processing apparatus 1 and aligned with their rack base 11b, respectively. Preferably, for this purpose, a centering adapter is used and the orientation of the Gestelloberteils 11a and the lower frame part 11b of each processing unit 10a-10d is carried out as in the DE 20 2014 004 374 U1 the applicant described. Thereafter, the processing modules 12 are used in these processing units 10a-10d and the module upper parts 12a and module lower parts 12b aligned with each other, preferably as in the DE 10 2014 007 732 A1 the applicant described. The machining device 1 formed thereby allows a plurality of machining operations to be carried out by successive, preferably cyclically advancing the workpiece or workpieces in a single clamping operation on the respective workpieces.

The described processing device 1 is also characterized in that it is possible in a simple manner to exchange processing units 10a-10d. Should z. Example, the second processing unit 10 b are replaced by the fixation effected by the fixing device 22 Gestellunterteils 11 b of the second processing unit 10 b on the frame bases 11 b of the first processing unit 10 a and the third processing unit 10 c by the retaining clips 23 "from the recesses 23 and 23 'are moved out.

In the above description, it has been assumed that, for positional alignment of the racks 11 of the processing units 10a-10d, first, the rack bases 11b are aligned with each other, and then, as described above, the respective frame top portions 11a of the processing units 10a-10d are aligned relative to the position-fixed rack bases 11b become. However, it is also possible for the aforementioned centering operation of the individual processing units 10a-10d to be carried out by first aligning the frame top parts 11a with one another, just as was the case above has been described for the frame bottom parts 11b, and then the respective frame bases 11b are aligned with the position-fixed frame top parts 11a. A combination of these two measures is possible, although this is not preferred.

In connection with the release of the fixing devices 22, the centering pins 20c are also removed from the centering devices 20 'and 20 "acting between the first and second machining units 10a and 10b and between the second and third machining units 10b and 10c Frame bottom part 11b of the second processing unit 10b has been released, it can be removed from the lower base 2b of the processing apparatus 1. If necessary, the module top 12a of the second processing unit 10b and the frame top 11a of this processing unit 10b are also removed from the processing apparatus 1. Now, instead of the like the above-mentioned processing unit 10b, a differently configured processing unit are inserted into the processing apparatus 1, the insertion process being carried out as described above: the lower base 2b of the further processing unit to be loaded is placed on the lower base frame 2b of the processing apparatus 1 and positioned by means of the centering devices 20 'and 20 "and fixed by the fixing means 22. Thereafter, the frame base 11b of the other processing unit is fixed to the lower base frame 2b of the processing apparatus 1 as described above. The frame base 11b and the frame top 11a of the further processing unit are then centered on each other as described above and then the corresponding module units are used.

In the Figures 6a and 6b In each case an alternative embodiment of a centering device 20 is shown. In the first embodiment according to FIG. 6a the centering element 20a of the centering device 20 is again formed by a recess 21. The complementary centering element 20b is not - as in the above with reference to the FIGS. 5a and 5b described centering device 20 - as a further recess 21 ', but as a projection 21 "is formed, which dips into the recess 21 of the centering element 20a. The projection 21" therefore also assumes the function of the centering pin 20c in the embodiment shown here.

This in FIG. 6b shown centering element 20 is similar to its basic structure after the centering element 20 of FIGS. 5a and 5b , It in turn has recesses 21 and 21 ', which, however, in the case shown here are triangular in shape, in particular have the shape of an equilateral triangle. The centering pin 20c then has a polygonal, in particular square cross-section. It will be apparent to those skilled in the art from the foregoing description that the embodiments of the centering device 20 described herein are merely exemplary in nature. The use of a semicircular recess is advantageous, but not mandatory. On the contrary, any curved or polygonal configuration of the recesses 21, 21 "is possible, as long as this enables a centering of two adjacent frame lower parts 11b of adjacent processing units 10a-10d.

In the FIGS. 6c and 6d Now further embodiments of the fixing device 22 are shown. In the embodiment of the FIG. 6c it is provided that the fixing device 22 is formed by a screw connection. The first fixing element 22a is thus a screw and the second fixing element 22b is designed as a bore provided with a corresponding thread.

The second embodiment of the fixing device 22 according to the FIG. 6d provides that the frame bases 11b adjacent processing units, for. As the processing units 10 a and 10 b, are held together by a clamping ring. The first fixing member 22a is formed as a recess 25a, as well as the second fixing member 22b as a recess 25b. In the recess formed by a clamping ring 25c can be used, which are the two adjacent Frame bottom parts 11b adjacent processing units 10a, 10b pulls each other and so fixed in position relative to each other.

The FIGS. 7 and the following show a second embodiment of a processing apparatus 1, which corresponds to its basic structure according to that of the first embodiment. Here, again by way of example, four processing units 10a-10d are provided (see in particular FIGS. 8 and 16 ), which - like the processing units 10a-10d of the first embodiment - a frame 11 with a frame top 11a and a frame base 11b and a processing module 12 with a module top 12a and a module base 12b (see FIGS. 15 to 19 ). Again, the Gestelloberteil 11a an upper platen 11a ", an upper frame plate 11a" and an upper pressure plate 11a '''and the frame base 11b a lower platen 11b', a lower frame plate 11b "and a lower pressure plate 11b '''on.

In the first embodiment, it is provided that the frame top parts 11a of the processing units 10a-10d are arranged on an upper base frame 2a and the frame bases 11b on a lower base frame 2b of the processing device 1, which are connected to one another via guide columns 3a and 3b and thus move relative to each other in the Processing device 1 are arranged, which in turn are each moved by a drive device such as a press with a press upper part and a press lower part. In the second embodiment, it is now provided that these base frames 2a and / or 2b are not formed as separate components, but are integrated into corresponding components of the drive device. This is especially true of the FIG. 7 seen. The processing device 1 shown there has, as a drive device, a press upper part 4a known per se and therefore not described any further, and a correspondingly formed press lower part 4b, which are relatively movable relative to one another. A press part, z. B. the press base 4b, may also be a stationary press table while the other press part, z. B. the press upper part 4a, is formed as a moving up and down press ram. The exact design of these two components 4a and 4b is not crucial here. As can be seen from the above figure, the frame top parts 11a of the processing units 10a-10d are arranged on the press top 4a and the bottom frames 11b on the press bottom 4b, wherein - as in the first embodiment - the module tops 12a on the frame tops 11a and the module bottoms 12b on the frame bottoms 11b - are preferably interchangeable - arranged. As a result, a synchronous lifting movement of the processing units 10a-10d is again achieved and, by a successive onward transport of the workpieces to be processed in the processing apparatus 1, they successively pass through the processing units 10a-10d. The integration of the upper base frame 2a in the press upper part 4a and / or the lower base frame 2b in the press base 4b a lower required installation height for the processing units 10a-10d is achieved because the upper base frame 2a and / or the lower base frame 2b due to this integration these two components in the press upper part 4a and / or the lower press part 4b as separate components of the processing device 1 accounts. The manufacturing accuracy of the processing device 1 is thereby increased in an advantageous manner, since shorter strokes are required.

Like from the FIGS. 7 and 8th It can also be seen that the individual processing units 10a-10d are fastened in their position as described below by means of clamping elements 30b on the press lower part 4b and by means of further clamping elements 30a on the upper press part 4a by the lower frame parts 11b being clamped by means of the clamping elements 30b formed on the claw here Press lower part 4b and the Gestelloberteile 11a are clamped by means of the here also - exemplary - pratzenförmig trained upper clamping elements 30a each on the press upper part 4a.

As in the first embodiment, a positional alignment of the Gestelloberteils 11b of each processing unit 10a-10d with respect to the associated frame base 11b of the respective processing unit 10a-10d is required.

In the first embodiment, it is provided for this purpose that a centering adapter is used to align the Gestelloberteile 11a of the processing units 10a-10d relative to the associated frame base 11b, as shown in the DE 20 2014 004 374 U1 the applicant is described. Such an approach is basically possible in the second embodiment. However, in the embodiment described below, another way of aligning the frame top 11a and the frame bottom 11b will be apparent to those skilled in the art from the description that also in the first embodiment, the manner of positional alignment explained below between two cooperating frame parts 11a, 11b can be used ,

In the second exemplary embodiment described here, it is provided that the alignment between the frame lower part 11b and the frame top 11a of the frame 11 of each machining unit 10a-10d takes place by means of a centering adapter 50a-50d, which is designed as described below, the design of these centering adapters 50a 50d represents a measure of independent patent-pending importance. The FIGS. 7 and 8th show the processing apparatus 1 with such Zentrieradaptern 50a-50d, which are arranged between the frame bases 11b and the frame top parts 11a of the processing units 10a-10d.

The FIG. 9 Now shows a plan view of the frame bases 11b of the adjacent processing units 10a-10d of the processing apparatus 1, the FIG. 10 shows a section through the first processing unit 10 a corresponding to the line AA of FIG. 9 , the FIG. 11 provides an enlarged view of part of the in FIG. 10 left portion of the processing unit 10a and the FIG. 12 is an exploded view of the processing unit 10a corresponding to the aforementioned section AA. The FIG. 13 shows two centering devices 60a and 60b, as used by the second embodiment for aligning the Gestelloberteile 11a relative to the corresponding frame bases 11b of the processing units 10a and 10b.

The simpler description of this alignment process should first be based on the above figure, the basic structure of in FIG. 13 illustrated centering devices 60a are described. The centering device 60a is divided into three centering units 61a, 61b and 61c, the first centering unit 61a having a centering element 62a, which cooperates with a complementary centering element 62b 'of the second centering unit 61b. In a corresponding manner, a second centering element 62b "of the second centering unit 62b cooperates with a centering element 62c of the third centering unit 61c of the centering device 60a. In the case described here, the centering elements 62a and 62c are designed as centering openings, while the complementary centering elements 62b and 62b ' are formed as Zentriervorsprünge.

Like from the FIGS. 9 to 12 As can be seen, the frame bases 11b of the processing units 10a and 10d, respectively, comprise a number of first centering units 61a of the above-described centering devices 60a. In the frame upper parts 11a, in turn, a corresponding number of third centering units 61c of the centering device 60a is provided. In the embodiment described here, it is provided that in the lower pressure plate 11b '''and in the upper pressure plate 11a''' a corresponding number of recesses 65 are present, in which the centering units 61a and 61c can be accommodated. But it is also possible that these centering units 61a, 61c are formed as integral parts of the corresponding components of the frame base 11b and the Gestelloberteils 11a.

For aligning the Gestelloberteils 11 a on the frame base 11 b of the first processing unit 10 a is - as in the FIGS. 7 . 8th . 10-12 shown - a centering adapter 50a used. Further centering adapters 50b-50d are used in a corresponding manner for aligning the upper frame parts 11a of the further processing units 10b-10d with respect to their frame bases 11b. The centering adapters 50a-50d have a main body 51 which has a number of recesses 52 corresponding to the number of centering devices 60a provided in a centering adapter 50a-50d, in each of which a second centering unit 61b of the centering devices 60a is inserted the centering elements 62b 'and 62b "of the second centering units 61b protrude beyond the main body 51 and thus interact with the corresponding centering elements 62a and 62c of the first centering unit 61a and the third centering unit 61c, respectively, as described below. The height of the centering adapter 50a corresponds to this preferably the height of the later to be mounted in the frame 11 processing module 12th

For positional alignment of the frame top 11a relative to the frame base 11b, the centering adapter 50a is placed on the frame base 11b of the processing unit 10a, in this case on the lower pressure plate 11b '' ', and moved until the first centering elements 62b of the centering devices 61b of the centering adapter 50a are in positional register the first centering elements 62a of the lower pressure plate 11b '' 'are aligned. The centering elements 62b 'of the centering adapter 50a, which are designed as centering projections, dip into the centering elements 62a designed as centering openings, so that a defined positional relationship is provided between the frame base 11b and the centering adapter 50a. In this then the centering adapter 50a is fixed by means of corresponding fastening means 32b on the lower frame plate 11b '' '.

In this case, it is preferred that the centering elements 62a in the form of a half-shell and the centering elements 62b 'cooperating therewith be in the form of half shafts projecting beyond the lower surface of the centering adapter 50a are formed. Such a measure has the advantage that in this way the position alignment of the centering adapter 50a to the frame base 11b and in particular to the lower pressure plate 11b '''is simplified, since by the coordinated shape cooperating centering 62a, 62b' the centering 62b 'of the centering adapter 50a itself to the centering elements 62a of the lower pressure plate 11b '''align. Each pair of cooperating centering 62a, 62b 'thus acts self-centering, since the half-wave projections of the centering 62b' slide in the half-shell-shaped centering of the centering 62a of the lower pressure plate 11b '''along until a corresponding centering position is reached. The centering elements 62a, 62b 'of the centering device 60a are thus preferably self-centering centering elements.

Now that the centering adapter 50a of the first processing unit 10a has been aligned with the frame lower part 11b and fastened there, the press upper part 4a together with the frame top part 11a is lowered. At this time, the frame top 11a is indeed attached to the press top 4a, but still changeable in its position. Upon further advancement of the frame top 11a, the centering elements 62b "of the centering adapter 50a engage with the centering elements 62c of the frame top 11a, causing the frame top 11a to be aligned in a defined position with the centering adapter 50a and thus with the frame bottom 11b The upper part of the frame 11a is fastened to the centering adapter 50a by means of further fastening elements 32a, whereby subsequent fixing of the upper frame part 11a is facilitated by means of the clamping elements 30a on the press upper part 4a. 32b and a moving apart of press upper part 4a and press base 4b and thus of the frame top 11a and frame base 11b of the centering adapter 50a is removed from the processing unit 10a.

In the described embodiment, it is preferably provided that, in addition to the centering devices 60a, further centering devices 60b are provided. The other centering devices 60b are - as in particular from FIG. 13 is apparent - formed according to the centering devices 60a. But it is envisaged that - as in particular from the FIGS. 9 to 12 it can be seen - preferably each pairs of centering devices 60a, 60b are used, wherein preferably each one pair of centering devices 60a, 60b are arranged in a common recess 52 and 65, respectively. But it is also possible to arrange the centering devices 60a and 60b in their own recesses 52 and 65, wherein preferably the further centering device 60b - as shown in the aforementioned figures - is offset by a defined angle to the first centering device 60a, preferably by 90 Degree, as shown in the figures. Such a measure has the advantage that this advantageously allows a two-dimensional alignment of the centering adapter 50a on the lower pressure plate 11b '''or the upper pressure plate 11a''' on the centering adapter 50a.

It can be seen from the above description that the described special design of the centering elements 62a, 62c or 62b ', 62b "as half-shells or half-shafts is not mandatory, but it is also possible to use a hemispherical shape of the centering elements 62b' instead of the half-waves. 62b "or a half-shell-shaped form of the centering elements 62a, 62c. This also makes it possible to achieve a two-dimensional alignment of the centering adapter 50a on the frame lower part 11b in a simple manner. But even this way of designing the centering 62a-62c is not mandatory. Rather, any form that allows a self-centering operation of the centering elements, conceivable. Of course, it is also possible to combine within one embodiment, half-wave and hemispherical centering, to name just one example. Furthermore, it is possible to access the self-centering function of the centering elements 62a-62c renounce by z. B. the centering 62b, 62b 'are formed as circular rods. The embodiment of cooperating centering elements described above is not mandatory.

Thereafter, as in the first exemplary embodiment, the second processing unit 10b adjoining the first processing unit 10a is aligned in a positionally accurate manner with respect to this. It will be on the FIG. 14 The lower frame part 11b in turn has one or more centering devices 20 - again two centering devices 20 'and 20 "in the case shown here - each having a centering element 20a, as with the first embodiment, which has a complementary centering element 20b of the lower frame part 11b of the second processing unit 10b adjacent to the first processing unit 10a The design and operation of the centering devices 20, 20 'and 20 "and the fixing devices 22, 22' and the alignment process have been described above in the first embodiment, so that reference may be made thereto.

After the lower frame part 11b of the second processing unit 10b has been aligned relative to the lower frame part 11b of the first processing unit 10a, this lower frame part 11b is fixed to the lower press part 4b by means of the clamping elements 30b. Then, as described above with reference to the first processing unit 10a, the frame top 11a of the second processing unit 10b is aligned relative to the rack base 11b by means of the centering adapter 50b, respectively, with the centering adapters 50c and 50b respectively, the rack top portions 11a of the third and fourth processing units 10c and 10d relative be aligned with the respective frame base 11b. In a corresponding manner, the frame bases 11b of the third and fourth processing units 10c and 10d are then aligned with respect to each other and fixed to the frame base 11b.

It will be apparent to those skilled in the art that the above-described procedure - aligning the frame top 11a relative to the frame bottom 11b of the first processing unit 10a, aligning the rack bottom 11b of the processing unit 10b adjacent to the first processing unit 10a, aligning the rack top 11a of the second processing unit 10b relative to its rack bottom 11b, aligning the lower frame part 11b of the third processing unit 10c adjacent to the second processing unit 10b, aligning the upper frame part 11a of the third processing unit 10c relative to its lower frame part 11b, etc. - not mandatory. Rather, the described alignment process can be varied within wide limits. Thus, it is possible to first align some or all of the frame bases 11b of the processing units 10a-10d with each other, and then successively align the frame top portions 11a with the respective shelf-aligned frame bases 11b or combine the above-described operations.

After the upper frame part 11a and the lower frame part 11b of at least one processing unit 10a-10d have been aligned on each other as described above, in the next step, the processing module 12 is aligned in the correct position to the frame 11 of the respective processing unit 10a-10d. This process is in the FIGS. 15 to 19 explained. The FIGS. 15 16 again shows an isometric view of the processing apparatus 1 according to FIG FIG. 7 or the processing units 10a-10d of FIG. 8 the difference between these two representations is that-as described above-in the representations of FIGS. 7 and 8th between the respective frame upper parts 11a and frame bases 11b of the individual processing units 10a-10d centering adapters 50a-50d are present, as also described above, the Gestelloberteil 11a and the frame base 11b of a respective processing unit 10a-10d align each other while the FIGS. 15 and 16 now show processing modules 12 recorded between the frame top 11a and the frame base 11b of each processing unit 10a-10d. Such processing modules 12 are known and can be designed as cutting, punching, bending, embossing or joining modules - to name but a few examples. The person skilled in the basic structure of such a processing module 12 is known, so that it need not be further described. Each processing module 12 has - as in the first embodiment - a module top 12a and a module base 12b.

The training and function of the processing modules 12 used in the described embodiment is from the FIGS. 17 to 19 seen. This can be characterized in that the procedure used in the centering adapters 50a-50d, namely to use centering devices 60a, 60b, also applies to the orientation of the module top 12a to the frame top 11a of each processing unit 10a-10d and / or to aligning the module bottom parts 12b the frame bases 11b is used. This measure also has patent-pending character. The centering devices 70a used for this purpose are basically constructed like the centering devices 60a, 60b described above, so that reference can be made to the above description of the same and corresponding components can be designated by the same reference numerals. The centering units 61a are recesses 75 corresponding to the recesses 75 of the lower frame part 11b of the processing unit 10a-10d used (see FIG. 9 ). In a corresponding manner, recesses 75 for the centering units 60c are provided in the frame upper part 11a of the processing units 10a-10d (see FIG FIGS. 17 to 19 ). The number of recesses 75 again corresponds to the number of centering devices 70a used in a processing module 12. The module upper part 12a and the lower module part 12b have the recesses 52 of the centering adapter 50a-50d corresponding recesses 52a and 52b, in which the centering units 71b described below are arranged. Again, it is again preferred that pairs of cooperating centering devices 70a be used such that, as with the centering adapter 50a-50d, the centering units 61a preferably couple a pair of cooperating centering devices 70a Recess 65 of the frame base, the centering units 61c of a pair of cooperating centering devices 70a preferably in a corresponding recess 65 of the Gestelloberteils 11a and the centering units 71b of a pair of cooperating centering devices 70a preferably in a common recess 52a, 52b are arranged. In that regard, reference may be made to the description of the corresponding components of the centering adapter 50a-50d. Furthermore, the German utility model DE 20 2018 002 245 referenced, in which a corresponding centering device for module centering is described. The disclosure of this utility model application is made subject of this application by this reference.

The essential difference between the centering devices 70a for centering the processing modules 12 in the racks 11 of the processing units 10a-10d and the centering devices 60a, 60b for centering the frame top parts 11a and / or the frame bottom parts 11b in the processing device 1 now results from the fact that each Machining module 12 is divided into two, that is a module upper part 12a and a lower module part 12b has, while the centering adapters 50a-50d are integrally formed. Accordingly, it is provided in the centering devices 70a, that the second centering units 71b - which correspond to their basic structure according to the centering units 61b of the centering devices 60a, 60b - are formed in two parts, such that the centering element 72b 'corresponding to the centering element 62b' from the bottom of the module lower part 12b and that the centering element 62b "corresponding centering element 72b" protrudes from the top of the module top 12a. The dividing line between the centering elements 72b 'and 72b "extends in the region of the upper surface of the module lower part 12b or the lower surface of the module top part 12. In these figures, the centering elements 62c of the upper frame part 11a and the centering elements 62a of the lower frame part 11b are again shown previously described for the positional alignment of these two frame parts 11a, 11b by means of the centering adapters 50a-50d as well as the module lower part 12b have the complementary centering elements 72b ', 72b "cooperating with the aforementioned centering elements 62a or 62c of the upper frame part 11a or lower frame part 11b, which in turn are preferably self-centering 11a and the lower frame part 11b of the processing units 10a-10d are moved and the complementary centering elements 72b 'of the lower module part 12b are moved over the centering elements 62a of the lower frame part 11. By a corresponding centering movement, the lower module part 12b aligns with the lower frame part 11b Module lower part 12b by means of fixing means 32b aligned on the frame base 11b set in a corresponding manner then the alignment process of the module upper part 12a relative to the frame top 11a carried out by - as described above with reference to the Modulunt Part 12b described - the module upper part 12a by the cooperating pairs of centering elements 62c, 72b "centered. After the alignment of the module upper part 12a, this is fastened by means of the fastening means 32a on the frame top 11a. In the first processing unit 10a, therefore, the frame 11 and the processing module 12 are aligned with each other. In a corresponding manner, the orientation of the processing modules 12 of the further processing units 10b-10d then takes place on the respective racks 11.
