Description

The invention relates to a device for embossing and / or punching a workpiece, in particular from cardboard according to the preamble of claim 1, and a method for attaching and / or adjusting a stamping and / or punching tool on a carrier in such a device according to the preamble of claim 6. Such a device and such a method are in US-A-5515749 disclosed

Devices of the type mentioned are used for example in punching and embossing machines, with which cardboard sheets, but also other materials such as paper or plastic, punched in one operation and / or provided with folding grooves and / or can be embossed.

Basically, such devices consist of a generally plate-shaped carrier and connected or connectable tools. For example, stamping or creasing elements, also called punching or creasing lines, are known for punching or grooving workpieces which are inserted into slots of the carrier.

Tools for embossing workpieces but also for punching are also known, which contain an embossing matrix and / or punching elements and are reversibly fastened to the carrier with screws via feedthroughs in the tool. Such embossing and / or punching tools require an exact positioning on the carrier, so that the embossing and / or punching takes place on the workpiece at the desired position.

In order to be able to precisely set the desired position of the embossing and / or punching to be produced by such embossing and / or punching tools, in particular in relation to further punched edges and rabbet grooves, a corresponding fine adjustment of the position of the stamping and / or punching tool on the carrier is required , This is known to be achieved by the diameter of the implementation in embossing and / or Punching tool is greater than the thread diameter of the mounting screws that attach the embossing and / or punching tool to the support via these feedthroughs. Before the non-positive attachment by tightening the screws, any position of the embossing and / or punching tool on the carrier is thereby adjustable within a specified by the diameters of screw thread and execution tolerance range. Such an arrangement also allows a readjustment of the tool on the carrier to compensate for tolerances in the workpieces to be machined.

In practice, it is often necessary to remove the embossing and / or punching tools from the carrier, for example, to arrange other tools at these locations. In a renewed attachment of the same embossing and / or punching tool, however, it is then necessary to determine the exact positioning of the tool on the support again in the context of a complex fine adjustment. It is therefore desirable to store a once found position of the tool on the support so that the tool can be immediately attached without re-adjustment in the same mounting position on the support.

For this purpose, a device of the aforementioned type is known in which the actual embossing matrix is connected to the carrier via a plate-shaped intermediate socket. This intermediate base is reversibly attached to the carrier with screws. The mounting position of the intermediate socket on the carrier is determined by dowel pins which are mounted on the carrier and engage in corresponding recesses of the intermediate socket. The embossing matrix, in turn, is fastened with screws to the intermediate base, in which case the desired fastening position can be determined in the context of a tolerance range predetermined by the diameters of the leadthrough and screw thread. By loosening the screw connections between the intermediate cam and the carrier, the intermediate socket with the embossing matrix still attached to it can be removed from the carrier. When re-fastening the position of the intermediate socket is predetermined by the dowel pins. The embossing matrix, which is still fastened on the intermediate base, therefore again assumes the same position without renewed adjustment.

The disadvantage of this solution is the complex structure of the embossing tool, since the embossing matrix is fastened to an intermediate base in order to determine its position. This intermediate socket must be made extremely accurate and therefore costly, so that the specified position of the tool on the carrier after a removal from the carrier is exactly taken again. In practice, many different embossing matrices are often used alternately at the same locations of a wearer. Each of these embossing matrices must be fixed to determine their position on one of these complex to produce intermediate socket.

In addition, the intermediate sockets can not be used flexibly for different fastening points. For each attachment point on a carrier or on different carriers each have their own, to the arrangement of the respective dowel pins exactly matched intermediate socket must be made. All in all, therefore, a large number of differently pronounced intermediate sockets must be produced, appropriately marked and kept ready.

Another disadvantage is the resulting due to the intermediate socket as an additional structural element high overall structure of the embossing and / or punching tool on the support. For standard dimensions, i. a total height of carrier and attached embossing tool of 23.8 mm and a support plate with a thickness of 18 mm, therefore, for the attachment of such a constructed tool on the support a cutout in the support with a depth of about 10 mm is required. For reasons of stability, a cutout of this order of magnitude must be spaced from the slots provided in the carrier for the punching or creasing lines. As a result, the positioning possibility for a stamping and / or punching tool with intermediate socket on the carrier plate is limited, in particular an attachment near the punching or creasing lines is not possible.

In this hand punching device, a top plate (punching tool) is fitted over a bottom plate (support) with the aid of guide pins which are fastened to the bottom plate and which are made to fit corresponding holes in the top plate. This will an exact, fixed predetermined arrangement of the top plate above the bottom plate allows. In this hand punching device is a Einjustieren the plates to each other, ie an adjustment or adjustability of the exact positioning to each other, not provided. Accordingly, a reproducibility of a once set position is not provided.

Out DE 298 02 231 U1 a device for injection molding of plastic parts or for punching sheets is known. In this device, a plurality of plates are arranged one above the other and aligned exactly with each other. To ensure the positioning of the plates to each other guide rods are provided. These guide rods reach through slots in the plates. In this way, each guide bar is supported in a direction relative to the plates with play. This game serves to compensate for the temperature expansion of the plates and thereby prevent tilting. For this purpose, the slots are aligned so that the exact guidance of the plates by the guide rods and thus the exact positioning of the plates is maintained. A Einjustieren the plates to each other, ie an adjustment or adjustability of the exact positioning to each other, and a reproducibility of a once set position are not provided in this known device.

11. k) in which the second recesses of the carrier form the mounting locations for reversibly securing the embossing and / or punching tool to the carrier,
12. l) with first feedthroughs in the embossing and / or punching tool at the locations which lie in the fastening position of the embossing and / or punching tool on the carrier over the first depressions of the carrier,
13. m) with second passages in the embossing and / or punching tool at the locations which lie in the attachment position of the embossing and / or punching tool on the carrier over the second recesses of the carrier,
14. n) with first attachment means for fixing the positioning means to the first passages of the embossing and / or punching tool, and
15. o) with second attachment means for attaching the embossing and / or punching tool via the second passages of the embossing and / or punching tool and the second recesses of the carrier to the carrier,
16. p) in which on the carrier a plurality of embossing and / or punching tools are fastened or fastened and the respective attachment point of various embossing and / or punching tools on the support by different arrangement of the recesses in the carrier, in particular the first wells, and a corresponding arrangement of associated feedthroughs of the respective embossing and / or punching tool clearly specified and not confused.

The designation of the wells with "first" and "second" serves to distinguish two different types of wells. The same applies to the analogous notation for bushings and fasteners.

In this device, a plurality of stamping and / or punching tools are mounted or attached to a carrier. In this case, the device according to the invention provides that the exact position of the stamping and / or punching tool adjustable on the carrier and thus adjustable according to the respective requirements. By way of example, the punching and / or embossing to be carried out with the tool can be adapted exactly to the imprint of the cardboard sheet by trialing a printed cardboard sheet. This adjustability is achieved on the one hand by the positive and / or non-positive usability of the positioning in the first wells of the carrier and on the other by the connection or connectivity between positioning and stamping and / or punching tool in any lying within a predetermined tolerance range positions to each other , even if the positioning means are inserted in the carrier. In this way, the exact position of the tool on the carrier is adjustable and thus adjustable.

Further, the device according to the invention allows the reproducibility of the once occupied, i. adjusted or adjusted, position of the embossing and / or punching tool on the carrier. This is achieved by first removing the tool from the carrier during disassembly with the positioning means attached thereto, i. the positioning means are pulled out of the first recesses. In a storage / storage of tools then the positioning remain attached to the tool, i. the position of the positioning means on the tool is maintained. Finally, when the tool is re-mounted on the carrier, the positioning means are simply re-inserted into the first extensions of the carrier, whereby the previous positioning between tool and carrier is restored and thus reproduced. This reproducibility of a once-adjusted positioning is thus achieved in the device according to the invention in that the embossing and / or punching tool with the positioning means attached thereto is detachably mountable on the carrier and again in the same position determined by the positioning means.

The advantage achieved by the invention is, in particular, that the once fixed position of the embossing and / or punching tool on the carrier by appropriate attachment of positioning means on the tool is stored or reproducible. These positioning need not be made individually for a particular attachment point, they can be standardized and are therefore with appropriate standardization the first wells in the carriers flexible, ie for different attachment points used. By the features of claim 1, therefore, a device is provided which allows in a simple manner the storage and thus the restoration of a once taken within a predetermined tolerance mounting position of a stamping and / or punching tool on a support.

Another advantage of the invention is that the total height of the embossing and / or punching tool over the possibly milled carrier surface over the total assembly height of a stamping and / or punching tool with intermediate socket according to the prior art is significantly reduced, since the positioning means in the Attachment of the embossing and / or punching tool are used on the carrier in the first wells of the carrier and thus make no difference or at least only a small contribution to the height of construction, in contrast to the intermediate base. As a result, for mounting an embossing and / or punching tool according to the invention on the carrier with standard dimensions (total height 23.8 mm, support plate height 18 mm) compared to the prior art at most a small milling in the carrier, for example, with a depth of about 2.5 mm compared to 10 mm in the prior art required. Such cutouts can be brought up to the possibly introduced in the carrier slots for punching or creasing without significantly affecting the stability of punching or creasing lines used therein. Thus, the embossing and / or punching device according to the invention also allows a positioning of a punching and / or creasing element near the punching or creasing lines. In addition, the production of a milling with less depth is simplified compared to the production of a deeper milling.

The advantage of the first and second bushings as well as the first and second fastening means is the provision of easy-to-use fastening systems by suitable arrangement of passages in the stamping and punching tool and by the associated fastening means. As a result, both the positioning means on the embossing and / or punching tool and the embossing and / or punching tool can be fastened or fastened to the carrier in a simple manner.

Another advantage results from the fact that the respective attachment point of different embossing and / or punching tools on the carrier by different arrangement of the recesses in the carrier and a corresponding disorder of the associated feedthroughs of the respective embossing and / or punching tool is clearly specified and therefore not confused , As a result, the accidental attachment of a stamping and / or punching tool is prevented at a wrong attachment point.

In an advantageous embodiment of the invention, the first and / or second recesses in the carrier are designed such that they pass through the carrier.

It is expedient if the cross section of the passages of the first and / or second passages in the embossing and / or punching tool is circular. Preferably, the first and second passages are formed substantially the same.

In a preferred embodiment, the first and second attachment means are generic, i. it is a similar fastener. It is particularly expedient to form the first and second fastening means such that they are distinguishable from each other. This can be achieved for example by a different color. Thereby, even when the embossing and / or punching tool is attached to the carrier, it can be seen which fastening means attach the tool to the carrier and which fastening means fix the positioning means on the tool.

• dass die ersten Vertiefungen an der dem Präge- und/oder Stanzwerkzeug zugewandten Oberfläche des Trägers einen ersten Bereich mit im Wesentlichen rechteckigem Querschnitt und daran anschließend einen zweiten Bereich mit kreisförmigem Querschnitt aufweisen, der vollständig vom Querschnitt des ersten Bereichs überdeckt wird, und
• dass die Positioniermittel einen ersten Bereich mit im Wesentlichen rechteckigem Querschnitt und daran anschließend einen zweiten Bereich mit kreisförmigem Querschnitt aufweisen, der vollständig vom Querschnitt des ersten Bereichs überdeckt wird.

A further advantageous embodiment of the invention provides that the outer shape and the outer dimensions of the positioning means at least partially correspond to the shape and dimensions of the first wells of the carrier. In addition, it can be provided that the first recesses in the carrier and the positioning means each comprise regions of different cross section. A concrete embodiment for this provides

• in that the first depressions on the surface of the carrier facing the embossing and / or punching tool have a first region with a substantially rectangular cross section and subsequently a second region with a circular cross section which is completely covered by the cross section of the first region, and
• in that the positioning means have a first region of substantially rectangular cross-section and subsequently a second region of circular cross-section which is completely covered by the cross-section of the first region.

This refinement has the advantage that the positioning means can be inserted into the first depressions only up to a depth determined by the configuration of the first and second regions of the first depressions and of the positioning means. The positioning therefore take when inserting a stop in the first recesses a defined position. Furthermore, the region with a substantially rectangular cross section ensures the resistance to rotation of the positioning means introduced into the first recesses.

Preferably, in such an embodiment of the invention, the cross-sectional dimensions (length, width) of the region of substantially rectangular cross-section in the first recesses in at least one direction are greater than the corresponding dimensions of the region of substantially rectangular cross-section of the positioning means. This allows easy removal of the positioning means used in the first recess, for example with a gripping tool, as the larger dimensions of the first recess intervention in the recess even when inserted positioning and thereby lateral engagement of the positioning is possible.

• die ersten Vertiefungen im Bereich mit im Wesentlichen rechteckigem Querschnitt eine Länge zwischen 9 mm und 13 mm, insbesondere von 11 mm, und eine Breite zwischen 4 mm und 8 mm, insbesondere von 6 mm, und eine Tiefe zwischen 0,5 mm und 2 mm, insbesondere von 1 mm, aufweisen, und/oder
• die Positioniermittel im Bereich mit im Wesentlichen rechteckigem Querschnitt eine Länge, die zwischen 0,5 mm und 2 mm, insbesondere 1 mm, kleiner ist als die Länge des Bereichs mit im Wesentlichen rechteckigem Querschnitt der ersten Vertiefungen, und eine Breite, die im Wesentlichen der Breite des Bereichs mit im Wesentlichen rechteckigem Querschnitt der ersten Vertiefungen entspricht, und eine Höhe, die im Wesentlichen der Tiefe des Bereichs mit im Wesentlichen rechteckigem Querschnitt der ersten Vertiefungen entspricht, aufweisen.

An advantage of this embodiment of the invention is when

• the first recesses in the region of substantially rectangular cross-section have a length between 9 mm and 13 mm, in particular 11 mm, and a width between 4 mm and 8 mm, in particular 6 mm, and a depth between 0.5 mm and 2 mm , in particular of 1 mm, and / or
• the positioning means in the area of substantially rectangular cross section has a length which is between 0.5 mm and 2 mm, in particular 1 mm, smaller than the length of the area of substantially rectangular cross section of the first recesses, and a width substantially equal to that of FIG Width of the region having a substantially rectangular cross-section of the first wells corresponds, and a height substantially corresponds to the depth of the region of substantially rectangular cross-section of the first recesses.

In the region of substantially rectangular cross-section of the first depressions, the larger side length of the cross section parallel to the surface of the carrier is designated by "length", and the "width" to the corresponding smaller side length. "Depth" here refers to the extent of this area in the carrier inside.

The terms "length" and "width" of the region of substantially rectangular cross-section of the positioning means are to be understood in analogy to the designations of the dimension of the first depressions. The term "height" in the positioning means corresponds to the term "depth" in the first recess.

The height of the circular region of the positioning means is in principle arbitrary. However, it should be at least 3 mm, preferably 5 mm, in order to ensure a stable form and / or adhesion to the first wells. However, it must not be so large that it protrudes when inserting the positioning in the first recess to the stop on the opposite side of the carrier.

The depth of the circular region of the first depression in the carrier must correspond at least to the length of the circular region of the positioning means. Advantageously, the circular region of the first recesses extends through the carrier.

The above-described embodiments of the invention may further be designed such that, when the positioning means are used until they stop in the first recesses, ie until the underside of the substantially rectangular area of the positioning means, which faces in the direction of the carrier, contacts the carrier, the surface of the carrier on the form the side facing the embossing and / or punching tool and the outwardly facing surface of the positioning means form a substantially planar overall surface. Advantage of this development is that the embossing and / or punching tool is applied directly to the surface of the wearer or can be applied.

The embodiments may expediently be designed in such a way that the positioning means used as far as the stop in the first depressions of the carrier are fixed in the carrier by positive and / or non-positive engagement of the regions with a round cross section in the direction parallel to the surface of the carrier. This means that the horizontal position of the positioning means and thus of the embossing and / or punching tool attached to them is exactly defined.

It is advantageous for fastening the positioning means that they are provided in a development of the invention with at least one internal thread. This is arranged so that it is accessible when using the positioning means in the first recesses of the embossing and / or punching tool facing side of the carrier. Preferably, these internal threads pass through the positioning means.

Furthermore, it is expedient if threaded screws are used as the first fastening means whose threads correspond to the internal thread in the positioning means. In a further embodiment of the invention, the second recesses of the carrier are provided with internal threads. These can be produced, for example, by inserting metal inserts with a corresponding internal thread into the second recesses.

Appropriately, here is the use of threaded screws as a second fastening means whose threads correspond to the internal thread of the second wells.

In a specific embodiment, the internal threads have the same diameter in the positioning means and in the second recesses. In particular, the nominal diameter of both internal threads can be between 1 mm and 8 mm, in particular 3 mm.

A further advantageous embodiment of the invention is that the cross-sectional dimensions of the first and second passages in the embossing and / or punching tool are substantially greater than the cross-sectional dimensions of the guided through the respective passages areas of the respectively associated first and second fastening means.

As a result, the tolerance range of the fastening position of the embossing and / or punching tool on the carrier is determined essentially by these cross-sectional dimensions. This has the advantage that the tolerance range is thereby predefined or predefinable in a simple manner.

In one embodiment of the invention, the diameter of the first and / or the second passages through the embossing and / or punching tool between 1 and 5 mm, in particular between 2 to 3 mm, preferably 2.5 mm, greater than the thread diameter of the respectively associated fasteners.

An embodiment of the invention provides that the positioning means made of metal, in particular aluminum or steel, or made of plastic.

Preferably, the bushings are produced by the embossing and / or punching tool with laser beam or drill or cutter. Furthermore, the production of the depressions in the carrier can be carried out with a laser beam or drill or milling cutter.

This unambiguous assignment of attachment points of a carrier to the tools also lets you use them for unambiguous assignment on multiple carriers. This prevents a tool from being placed on a wrong carrier.

To determine the orientation of the embossing and / or punching tool at the respective attachment point to the carrier, it is advantageous to make the arrangement of the wells in the carrier and according to the arrangement of the associated feedthroughs of the embossing and / or punching tool and thereby securing the tool only in one orientation.

In a further advantageous embodiment of the invention, the carrier is designed as a carrier plate. Conveniently, it consists essentially of a pressure-resistant plastic or composite material, in particular hard paper or glass braided fiber composite material (eg Pertinax ®) or composite of synthetic resin and glass fabric (eg Vetronit®), or of metal, in particular aluminum or steel.

Preferably, the carrier or the carrier plate and thus also the entire device for embossing and / or punching is provided to carry out a substantially linear movement in an embossing and / or punching machine, i. with the side of the carrier to which the punching and / or creasing and / or embossing tools are attached and / or effective, fed substantially straight to the workpiece to be machined and - after the bear newspaper - to be moved back again.

In a further embodiment, the embossing and / or punching tool is in one piece, it may consist essentially of metal, in particular brass or magnesium or aluminum or steel, or of pressure-resistant plastic.

In an alternative embodiment, the embossing and / or punching tool comprises a base plate and an embossing and / or stamping means mounted thereon. The base plate can essentially be made of a pressure-resistant plastic or a composite material, in particular multi-layered, in particular hard paper or glass braided fiber composite material (eg Pertinax®) or composite of synthetic resin and glass fabric (eg Vetronit®), or of metal, in particular aluminum or steel, or made of wood. The embossing and / or punching means may be made of metal, in particular brass or magnesium or aluminum or steel, or pressure-resistant plastic or one, in particular multilayer, composite material, in particular hard paper or glass braided fiber composite material (eg Pertinax®) or composite material of synthetic resin and glass fabric ( eg Vetronit®).

In an expedient embodiment of the invention, punching and / or creasing elements for punching and / or creasing a workpiece, in particular cardboard, are used or can be used on the carrier to which one or more embossing and / or punching tools are fastened or fastened , This creates a device that - used in a punching and embossing machine - allows the stamping, grooving and embossing of a workpiece in a single operation.

The described positioning means can be designed as separate parts. But they can also be designed as components of the embossing and / or punching tool.

Overall, these embodiments provide a device for embossing and / or punching a workpiece with a variable, yet easily reproducible attachment position of a stamping and / or punching tool on a carrier. The positioning means used for this purpose can be used flexibly, i. independent of a concrete embossing and / or punching tool and independent of a particular mounting position. They are therefore standardizable and therefore easy to manufacture.

Corresponding parts are provided in the Figures 1 to 8 with the same reference numerals.

1 shows an embodiment of a device for embossing and punching 2 is shown. In the slots of a carrier, which is designed here as a support plate 3, a plurality of punching elements 4 are used for punching a workpiece and creasing elements 5 for the grooves of a workpiece. Furthermore, a stamping and / or punching tool can be seen here as a pure embossing tool 6 is executed and is mounted on the support plate 3. In addition, several first depressions 7, second depressions 8 and positioning means 9 inserted into the carrier plate 3 can be seen. In the affixing of the first depressions 7 and second depressions 8, no regularity can be discerned. As a result, the passages of the embossing and / or punching tools which can be attached over the respective depressions should be arranged individually corresponding to the respective depressions and thus ensure a non-interchangeable mounting of various embossing and / or punching tools on the carrier plate. In Figure 1 it can also be seen that the points of the support plate 3, where there is the possibility of attaching embossing and / or stamping tools are formed as a reduction 22, ie they are lowered by milling relative to the support plate surface 21, for example about 2.5 mm.

1 shows the embossing tool 6 mounted on the carrier plate 3 as an enlarged detail of FIG. The embossing tool 6 is surrounded in the illustrated example by creasing elements 5 inserted in the carrier plate 3. The embossing tool 6 is composed of a base plate 10 and an embossing means 11 mounted thereon. The embossing tool 6 is connected via first feedthroughs (not shown) and via first fastening means, here first screws 12, with positioning means 9 (not shown in FIG. 2, see FIG 7 and FIG. 8). The first screws 12 are provided with first shims 13. Furthermore, the embossing tool 6 is fastened to the carrier plate 3 via second fastening means, here second screws 14. The second screws 14 differ in their color (shown in black in FIG. 2) from the first screws 12 (shown in white in FIG. 2). The second screws 14 are provided with second washers 15.

3 shows another embossing tool 16 in the unassembled state, without attached positioning means. This embossing tool 16 corresponds in its structure to the embossing tool 6 of FIG 1 and FIG 2, it is composed of a base plate 17 and an embossing means 18 mounted thereon. The first passages 19 and the second passages 20, which are identical here, can be seen here. The first passages are used to attach the positioning means on the embossing tool, the second Bushings of the attachment of the positioning tool to the support plate (both not shown in FIG 3). The first passages 19 and the second passages 20 in the embossing tool 16 are mounted at different locations of the embossing tool than the passages in the embossing tool 6 of FIG. 1 and FIG. 2. The embossing tool 6 contains the first and second passages at the points at which the first Screws 12 and the second screws 14 can be seen. Due to this different arrangement of the implementation, the embossing tools 6 and 16 can be attached to the support plate 3 only at the specific locations for them, a swap is not possible. In addition, the arrangement of the bushings allows for both embossing tools 6 and 16 mounting on the support plate 3 only in one orientation. As a result, a twisted attachment of the embossing tool, for example, by 180 °, prevented.

1 shows first recesses 7, second recesses 8 and positioning means 9 inserted in first recesses 7. FIG. 4 shows the countersink 22 of the region of the carrier plate 3 milled into the carrier plate surface 21, on the embossing and / or punching tools can be attached. Furthermore, the concrete embodiment of the first recesses 7 can be seen with a region having a substantially rectangular cross section 23, wherein the corners 25 of the rectangle 24 are rounded. A region of circular cross-section 26 which extends through the carrier plate (not shown) adjoins the region of rectangular cross-section 23. It can be seen that the cross section parallel to the support plate surface 21 of the region of substantially rectangular cross section 23 covers the cross section parallel to the support plate surface 21 of the region of circular cross section 26.

It can also be seen in FIG. 4 that the second recesses 8 are formed in the exemplary embodiment shown here with a circular cross section. In the second recesses 8 thread 27 are introduced by pressed into the second recesses 8 metal inserts 28. These threads 27 serve to receive the second screws 14 and thus the attachment of a stamping and / or punching tool 6, 16, 34 on the support plate. 3

Furthermore, it is shown in FIG. 4 that the positioning means 9 are inserted into the first recesses 7 of the carrier plate 3. This results in a positive connection and / or adhesion (not shown) between the positioning means 9 and the first recesses 7, so that the positioning means 9 in the horizontal direction, i. parallel to the carrier plate surface 21, are fixed. It can also be seen in FIG. 4 that internal threads 29 are introduced into the positioning means 9 and pass through the positioning means 9 (see FIG. 5). This internal thread 29 serve to receive the first screws 14 and thus the attachment of the positioning means 9 on a stamping and / or punching tool 6, 16, 34. In the illustrated embodiment, the internal thread 29 in the positioning means 9 correspond to the threads 27 in the second recesses eighth ,

A specific embodiment of the positioning means 9 is shown in FIG. 5 from two different viewing directions. It can be seen that the positioning means 9 are composed of a region with a substantially rectangular cross-section 30 and a region of circular cross-section 31. The rectangle 32 of the positioning means 9 is curved on its narrow sides 33 to the outside. The dimensions of the positioning means 9 are chosen so that they can be used in the first recesses 7 and when fully used to the stop with the lowering 22 form a flat surface (see FIG 4). It can be seen in FIG. 4 that the length a of the region of essentially rectangular cross-section 30 of the positioning means 9 is smaller than the length b of the region of essentially rectangular cross-section 23 of the first depressions 7. This results in a simple removal of the positioning means 9 made possible from the first recesses 7. The width c of the region of substantially rectangular section 30 of the positioning means 9 and the width d of the region of substantially rectangular cross section 23 of the first recesses 7 are substantially equal.

6 shows the top view of a further embossing tool 34, which is designed in one piece, that is not two-part consists of a base plate with embossing means mounted thereon. The attachment of this embossing tool 34 on the support plate 3 is shown with reference to the sectional drawings 7 and FIG 8 along the sectional lines AA and BB.

It can be seen a lowering 22 of the support plate 3 in the area in which embossing and / or punching tools can be mounted on the support plate, with respect to the support plate surface 21. It can also be seen how the positioning means 9 is inserted into the first recess 7. The region of circular cross-section 31 of the positioning means 9 is positively and / or non-positively connected to the region of circular cross-section 26 of the first recess 27. The region of substantially rectangular cross-section 30 of the positioning means 9 is up to the stop, i. until its underside 36 contacts the support plate 3 in the first recess 7, it is introduced into the region of substantially rectangular cross-section 23 of the first recesses 7. The positioning means 9 forms with the lowering 22 a flat surface on which the integral embossing tool 34 rests.

The positioning means 9 is attached via the first passage 19 of the embossing tool 34 with a first screw 12 on the embossing tool 34. On the first screw 12, a first washer 13 is attached. The embossing tool 34 is attached via the second passage 20 with the second screw 14 to the second recess 8 of the support plate 3. At the second screw 14, a second washer 15 is attached. The first washer 13 and the second washer 15 are formed identical.

The first screw 12 and the second screw 14 sink completely into the recesses 35 of the embossing tool 34 when they are screwed into the respective thread as far as possible. This ensures that the screw heads do not impede the embossing process.

FIG. 7 shows that the first recesses 7 and the second recesses 8 pass through the carrier plate 3.

It can also be seen in FIG. 7 that the diameter of the first feedthrough 19 in the stamping tool 34 is significantly greater than the thread diameter of the first screw 12. The same applies - in the concrete exemplary embodiment even with identical dimensions - for the diameter of the second feedthrough 20 in the stamping tool 34 and the thread diameter of the second screw 14. As a result, the screws 12 and 14 in relation to the bushings 19 and 20 are horizontal, ie parallel to the carrier plate surface 21, mobile. This results in the variability of the exact mounting position of the embossing tool 34 on the support plate. 3

The once adjusted position of the embossing and / or punching tool 6, 16, 34 on the support plate 3 can be stored in that this position is initially determined by tightening the second screw 14. As a result, the embossing and / or punching tool 34 is fixedly mounted on the second recesses 8 of the carrier 3 via the second passages 20. The actual storage of the position, which allows the exact restoration of this position after a decrease of the tool 34 from the carrier 3, is carried out by subsequent tightening of the first screws 12. As a result, the positioning means 9 inserted into the first recesses 7 on the embossing and / or Punching tool 6, 16, 34 attached. The embossing and / or punching tool 6, 16, 34 can now be removed from the carrier 3 by loosening the second screw 14. Since the positioning means 9 continue firmly over the first screws 12 with the embossing and / or punching tool 6, 16, 34 are connected, they are taken out of the first recesses 7. When re-mounting the embossing and / or punching tool 6, 16, 34 on the support plate 3, the original position by inserting the embossing and / or punching tool 6, 16, 34 fixed positioning means 9 in the first recesses 7 of the support plate 3 reproduced. The re-attachment of the embossing and / or punching tool 6, 16, 34 on the support 3 is again by tightening the second screw 14th
