Description

The present invention generally relates to an improved punching apparatus in a stamping operation of a mechanical body, typically for punching a sheet.

• • eine erste, oben angeordnete Baugruppe
• • und eine zweite, der ersten Vorrichtung gegenüber angeordnete Baugruppe.

In the machine industry, the stamping or punching of a sheet usually uses a punching machine, typically a press or the like, which comprises:

• • a first, top-mounted assembly
• • and a second, the first device arranged opposite assembly.

• - eine obere Aufnahme,
• - eine den Stanzstempel tragende Vorrichtung, in der den Stanzstempel zum Lochen eines Bleches eingebracht wird
• - und einen Stanzstempel.

The first assembly includes:

• an upper receptacle,
• - A device carrying the punch, in which the punch is introduced for punching a sheet
• - and a punch.

These parts are typically mounted to the underside of an upper die of a punching and punching press for punching or punching a metal sheet, the upper die being moved into a vertical downwardly directed movement, i. in the direction of a fixed lower tool or the like., Is set.

The punch is attached to this upper receptacle and held in place by a mechanical lock.

This upper receptacle is in turn attached to the upper tool, so that the punch and the associated upper receptacle are firmly connected to the upper tool.

• - eine untere Aufnahme oder Matrizenträger,
• - eine „Matrize“, welche auf der oberen Seite mit einer Bohrung versehen ist, welche dazu geeignet ist, den unteren Teil des Stanzstempels aufzunehmen, nachdem der Stanzstempel abgesenkt worden ist und die Blechtafel gelocht hat.

The second assembly includes:

• a lower receptacle or die carrier,
• - A "die", which is provided on the upper side with a bore which is adapted to receive the lower part of the punch after the punch has been lowered and the sheet has punched.

These components are typically mounted on the top of a punch and punch press tool for punching or punching a metal sheet, this die being held firmly and forming the counterpart to which the die carrier to which the sheet to be punched is applied is applied.

When punching or punching the upper receptacle, which is connected to the upper tool, also lowered when lowering the upper tool and as a result, the punch carrier is moved with the corresponding punch in the direction of the metal plate to be punched and pressed against it.

The metal sheet is punched by printing the punch and after punching the path of the upper tool and thus the punch is continued until the end portion of the punch into this opening or bore, with which the lower die is provided introduced.

Since this is already known from the prior art, a further detailed description is omitted here.

In an industrial stamping, especially in the processing of metal sheets in the automotive industry, it has proven to be very advantageous and often necessary to perform punching operations with great accuracy but also with a certain flexibility in the choice of the correct position of the punch and the corresponding die, ie it becomes necessary to change accurately both the position of the punch and the position of the corresponding die.

• DE 102015006678 , DE 112007002925 , DE 102007037757A1 und DE 102005022757B3 .

In order to be able to change the position of the punch exactly while maintaining the position of the upper receptacle and the lower receptacle as well as the corresponding stamp carrier and the corresponding die carrier, various solutions have been proposed, for example published by the following patents:

• DE 102015006678 . DE 112007002925 . DE 102007037757A1 and DE 102005022757B3 ,

These solutions have been found to be effective in various dimensions to solve the problem of how to controllably and accurately adjust the position of a punch and the corresponding die.

However, these have in practice and further have a common drawback with respect to the prior art in that it becomes necessary to remove the punch carrier from the upper tool and the die carrier from the lower tool.

In order to carry out these expansion steps, it becomes necessary to intervene manually in the inner space between these devices. But if the gap is too small and difficult to access, as is usually the case, These handles are very difficult and especially time consuming.

Since such operations must be carried out in an action environment where competition is extremely strong, they often become very uneconomical and thus completely undesirable.

It would therefore be desirable and therefore object of the present invention to provide one or more devices which solve the above-mentioned problem by allowing a change in the position of the punch and the die while maintaining the punch and the corresponding die in alignment, and both are very inexpensive as well as simple, can be manufactured with existing technology and are subject to no further disadvantages.

This object is achieved by several elements and devices which are manufactured and work according to the attached claims.

Therefore, in the following description, when using terms such as "top / top", "bottom / bottom", "top", "bottom", "side / side", etc., it is implicitly referenced solely to these figures but without any limitation on the content of the invention, which may be applied to any stamping machine of any spatial orientation.

Furthermore, it appears to make sense to specify, although such clarifications are completely superfluous for the expert, that the invention is applicable to any stamp type, especially on punches of the type "BALL-LOCK".

How out 1 As can be seen, the punching machine comprises an upper tool 1 which is a lower surface 2 on which it is mounted, and a punch carrier 3 , which points down, and of which the punch 4 extends downwards.

For the sake of simplicity, the representation of the scraper (or "stripper") is omitted in this and following figures, since this is immaterial to the content of the invention.

How out 1 can be seen, located below the punch carrier 3 and at some distance from this a Matrizenträger 5 which is an upwardly pointing and to the punch carrier 3 aligned die 6 contains.

The Matrizenträger 5 is in turn with its lower side on a lower tool 7 attached.

According to the prior art, the lower tool is usually firmly attached to the ground. The upper tool 1 is alternately operated with a vertical up and down movement, so that the punch 4 on the surface of between the punch 4 and the matrix 6 located sheet metal 9 can work. For the sake of clarity, the sheet is 9 as shown removed from the punching machine. The arrows "A1" and "A2" indicate the movement horizontally in the plane with which the sheet metal 9 between the punch 4 and the matrix 6 is introduced.

According to the invention with reference to the figures, the punch carrier 3 on its upper surface 10 a downwardly open, in cross-section substantially square recess 11 on, so the recess 11 is formed as a rectangular prism with square base, the edges are parallel to each other.

With reference to the 2 and 3 are three separate recesses 12 . 13 . 14 formed, which each both upwards, ie on the upper surface 10 , as well as to the upper section of this depression 11 are open.

As in 2 shown, these recesses 12 . 13 . 14 each with the recess 11 practically connected.

There are two of these recesses 13 and 14 arranged on opposite sides of the recess, the third recess 12 is on the third page of the recess 11 arranged.

In the figures as well as in the description, reference is made to a punch carrier with three ( 3 ) Recesses 12 . 13 . 14 Referenced. However, it is understood that the number of recesses can be varied. In this case, for example, two or four recesses may be provided, the possibility to provide four recesses, less preferred, since the recesses must be accommodated in a single punch carrier, the outer dimensions should be kept as low as possible advantageous.

Regarding 2 and 3 On the bottom side of these recesses in each case a corresponding downwardly facing through hole 12A . 13A and 14A formed, each through the entire material thickness of the tool carrier 3 parallel to the side walls of the recess formed as a rectangular prism 11 go through (see in particular the 2 . 3 and 4B ).

As shown in the figures, especially in the 2 and 3 , are three separate waves 20 . 30 . 40 each in the corresponding through holes 12A . 13A and 14A taken and these are constructive parallel to each other, the waves are also parallel to each other.

Every wave 20 . 30 . 40 each protrudes within a recess 12 . 13 . 14 into it.

At every wave 20 . 30 . 40 each becomes an arm 21 . 31 . 41 firmly attached, which extends orthogonal to the respective shaft.

The geometry, dimensions and positioning of the described elements with respect to each other are determined so that each arm is adapted to within the respective recess 12 . 13 . 14 to be received, and dimensioned so that the corresponding arm in turn rotating the shaft in the corresponding bore and thereby can move from a first position within the respective recess in a new position in which they are within the recess 11 protrudes.

As will be explained in more detail below, each shaft is provided at the respective lower end with corresponding rotary drive devices, preferably with hexagonal wrenches.

7 and 7A show a simple assembly, which consists of a cylindrical shaft 20 which stands in the direction of one of its ends with one arm 21 which is fixed to the shaft 20 is connected and a regular substantially flat surface 21A having.

A cuboid, rectangular element or wreath 26 has inside a substantially cylindrical and to the end faces of the wreath 26 parallel housing 27 (please refer 3 ) and is to suitable, the punch 4 record in a conventional manner.

The wreath 26 has such external dimensions that it fits exactly but smoothly within the recess 11 ( 3 . 4A . 4B . 6A ), and is adapted to be displaced within it, so that it from below from the recess 11 can be taken out.

In particular, if the wreath 26 is not specially held above, this falls free from the depression 11 out.

Outside shows the wreath 26 four faces 26A ( 3 ) on. Here we mean the two in 3 not shown, by the body of the wreath 26 concealed faces. These non-visible end surfaces are denoted by the reference numerals 26B and 26C characterized.

Each face 26A , along with the two invisible (and thus in 3 not shown) end faces 26B and 26C , Has corresponding first individual openings: The end face 26A has an opening 28A on, the invisible face 26B has a corresponding opening 28B on and analog has the invisible face 26C a corresponding opening 28C on. As described above, the two openings can also be represented on the non-visible end faces, as these through the body of the garland 26 to be covered.

Note that the openings on the invisible faces of the garland 26 out 3 same as the opening explained in detail below 28 to be discribed.

Regarding 2 and 3 , are on the front surfaces 26A , ( 26B ...) of the wreath 26 corresponding thin flat elements 29A . 29B . 29C attached, which at the respective end faces 26A , ( 26B and 26C , not visible) of the wreath 26 in a manner known per se, eg as in 3 shown by corresponding easily removable clamping elements, such as bolts 35 , which are fixed by the respective flat elements 29A . 29B . 29C be pushed through and stop it at the respective end faces.

Note that here is also a fourth flat element 29D is shown. However, this is not designed and positioned to serve as a corresponding insertion opening, but to achieve the required thickness for proper positioning. Therefore, it has no through hole.

Furthermore, the flat elements 29A . 29B . 29C preferably on the (nearly) entire extent of the opposite corresponding end faces of the ring 26 arranged, and are so dimensioned that the wreath complete with the corresponding flat elements 29A . 29B . 29C , completely in the depression 11 can be inserted without clear empty spaces (see 5A and 6A ).

Every flat element 29A . 29B . 29C comes with a corresponding second opening 50 . 51 . 52 Mistake.

The first openings 28A , (and 28B, and 28C, the latter not being visible) and the second openings 50 . 51 . 52 are formed, designed and arranged with respect to each other so that they substantially coincide, so that they each form individual passages, which from the outside of the corresponding recesses partially in the garland 26 be introduced.

After the assembly, which from the wreath 26 , the corresponding flat elements 29A . 29B . 29C , and the stamp to be inserted inside the rim 4 exists, built together and from below into the depression 11 was plugged, resulting in a complete stamp-wreath stamp carrier existing assembly, the position of the punch of course from the position of the ring 26 depends, which in turn depends on the thickness of the corresponding flat elements.

The essence of the invention is namely to determine the thickness of the individual flat elements so that the garland 26 exactly the desired position occupies. So that the wreath 26 , and thus the stamp 4 , assuming a new position, it is sufficient to exchange the flat elements with other flat elements having different thicknesses.

• - der Arm 21 wird in den aus der zweifachen, zur Öffnung 28A des Kranzes 26 gewandten Öffnung 50 gebildeten Durchgang eingeführt,
• - der Arm 41 wird in den aus der Öffnung 52 und 28C (nicht sichtbar) gebildeten Durchgang eingeführt.

After installation of the complete, consisting of stamp wreath punch carrier assembly, the garland is suitably provided with these flat elements with the desired thickness, the previously in the corresponding through holes 12A . 13A and 14A introduced waves 20 . 30 e 40 turned so that the corresponding arms 21 . 31 and 41 in the corresponding flat elements 29A . 29B . 29C be inserted as follows:

• - the arm 21 gets in from the double, to the opening 28A of the wreath 26 skilful opening 50 introduced passage formed,
• - the arm 41 gets in from the opening 52 and 28C (not visible) formed passage.

The same is true for the rest of the arm 31 and the corresponding openings 51 and 28B (not visible) on the respective flat element and on the respective end face of the ring 26 ,

• - nicht nur eine genaue Position innerhalb der Vertiefung 11 des Stempelträgers 3 einnimmt, da diese Position direkt von der Dicke der flachen Elemente 29A, 29B, 29C abhängt,
• - sondern auch stabil innerhalb der Vertiefung 11 gehalten wird.

In summary, when the waves 20 . 30 . 40 after the installation of the wreath 26 and the belonging to this, just described elements existing assembly are rotated so that the corresponding arms 21 . 31 and 41 are introduced into the corresponding double openings, and the assembly is released, it is clear that the garland 26 through the flat elements 29A . 29B . 29C

• - not just an exact position within the pit 11 the stamp carrier 3 occupies that position directly from the thickness of the flat elements 29A . 29B . 29C depends
• - but also stable within the depression 11 is held.

Regarding 2 and 2A in doing so comes the outer wall of the respective flat elements 29A . 29B . 29C with the corresponding vertical inner wall (see 3A and 2 ) of the depression 11 in Appendix. Of course, then determines the mutual effect of the elements, the position of the wreath 26 and thus of the associated stamp 4 ,

For better clarity, here ( 2 ) only two vertical walls 11A . 11B the depression 11 represented as the rest, in abutment with the flat elements 29A and 29B coming walls are not visible.

5B shows a symbolic projection overall view from above with the stamp carrier 3 the wreath 26 , the waves 20 . 30 and 40 , and the corresponding flat arms 21 . 31 . 41 , as well as the flat on the corresponding vertical walls of the wreath 26 attached elements 29A . 29B . 29C , wherein the arms are not introduced in the respective passage openings. 5A shows the same arrangement, however, in a central, vertical cross-sectional view, wherein the punch 4 and the corresponding wreath 26 and the corresponding flat elements 29A and 29C from the wreath 26 are pulled out, as these by bolts 35 on the wreath 26 are connected, which is pulled out of the punch carrier here.

6B and 6A show corresponding representations 5B and 5A but where are the arms 21 . 31 and 41 are completely inserted in the respective passage openings.

The exact position of the arms is indicated by corresponding dotted lines.

• - in der simulierten Draufsicht aus 3 folgt die Nummerierung der Wellen und der entsprechenden flachen Elementen einer im Uhrzeigersinn umlaufenden Reihenfolge,
• - in 3A folgt die Nummerierung dieser Elemente, Wellen, flachen Elemente etc. einer Reihenfolge gegen den Uhrzeigersinn. Im letzten Fall wird die Öffnung 52, welche dazu geeignet ist, sich an der Öffnung 28C ebenfalls anzuschließen, in einer Darstellung an der entsprechenden äußeren Wand des Kranzes 26 gezeigt.

Since it was considered useful, a slightly different overall presentation 2 and 3 in which two pairs of corresponding openings are also shown, is also the 3A enclosed, which is an analogue view 3 but with the following difference:

• - in the simulated plan view 3 follows the numbering of the waves and the corresponding flat elements of a clockwise circulating order,
• - in 3A follows the numbering of these elements, waves, flat elements, etc. of a counterclockwise order. In the latter case, the opening 52 which is adapted to the opening 28C also connect, in a representation on the corresponding outer wall of the wreath 26 shown.

For the rotation of the waves it is sufficient to connect the corresponding lower end to corresponding devices, e.g. preferably inner terminals which are adapted to be operated with hex keys, which are adapted to control their rotation.

As the figures show, the one with the stamp 4 and the corresponding flat elements 29A . 29B . 29C completed wreath 26 attached by lifting from below, without any removal of the stamp carrier 3 from the tool 1 within the recess 11 the stamp carrier 3 becomes necessary.

Finally, the thickness of the flat elements determines 28A . 29B . 29C ... the exact position of the punch 4 to the wreath 26 and thus to the stamp carrier 3 ,

Of course, if the thin flat elements 29A . 29B . 29C ... replaced by similar thin flat but different thickness elements, the position of the punch 4 Changed accordingly, as the distance of each wall of the wreath 26 to the respective opposite end face of the recess 11 exactly depends on the thickness of the corresponding flat element.

1. a) Mit einem Schraubendreher oder (Sechskant-)Schlüssel innerhalb der Bohrungen 12A, 13A, 14A eingreifen und die Wellen 20, 30, 40 und die entsprechenden Arme 21, 31, 41 so zu drehen, dass diese aus folgenden Öffnungspaaren ausgebracht werden;
2. b) -- 50 mit 28A -- (3) dann: - 51 mit der entsprechenden Öffnung 28B (3A) an der entsprechenden Stirnfläche des Kranzes 26; dann: -- 52 mit der entsprechenden Öffnung 28C an der entsprechenden Stirnfläche des Kranzes 26.
3. c) Da der Kranz nicht mehr oben durch das Zusammenwirken zwischen der oberen Seite der Arme und der oberen, jedoch nach unten zeigenden Seite der Öffnungen 50, 51 und 52 gehalten wird, fällt dieser frei durch die Schwerkraft heraus und somit sich aus der Stanzmaschine befreit.
4. d) Nun kann man am Kranz sehr leicht arbeiten, da dieser einfach mit den Händen gehalten werden kann.
5. e) Die Bolzen 35 werden gelöst und die dünnen flachen Elemente 29A, 29B, 29C werden befreit.
6. f) Diese werden dann durch andere dünne flache Elemente ausgetauscht, welche eine solche Dicke ausweisen, dass es dem Kranz 26 und somit dem entsprechenden Stempel ermöglichen, eine neue gewünschte Position einzunehmen.

This implies that it is sufficient according to the present invention, if, for some reason, a change in the position of the stamp, for example, even slightly, is desired to perform the following simple operations:

1. a) Using a screwdriver or (hexagon) wrench inside the holes 12A . 13A . 14A intervene and the waves 20 . 30 . 40 and the corresponding arms 21 . 31 . 41 to turn so that they are applied from the following pairs of openings;
2. b) - 50 with 28A - ( 3 ) then: - 51 with the corresponding opening 28B ( 3A ) on the corresponding end face of the ring 26 ; then: - 52 with the corresponding opening 28C at the corresponding end face of the wreath 26 ,
3. c) Since the garland is no longer up by the interaction between the upper side of the arms and the upper, but downwardly facing side of the openings 50 . 51 and 52 is held, this falls free by gravity and thus freed from the punching machine.
4. d) Now you can work on the wreath very easily, as this can be easily held with your hands.
5. e) The bolts 35 are solved and the thin flat elements 29A . 29B . 29C will be released.
6. f) These are then replaced by other thin flat elements, which have such a thickness that it is the wreath 26 and thus allow the corresponding stamp to assume a new desired position.

• -- 50 mit 28A --,
• -- 51 mit der entsprechenden Öffnung 28B an der entsprechenden Stirnfläche des Kranzes 26 -, und
• -- 52 mit der entsprechenden Öffnung 28C an der entsprechenden Stirnfläche des Kranzes 26.

If the wreath and the corresponding stamp 4 inside the stamp carrier 3 reinstalled, ie in the recess 11 be brought back, then takes the wreath 26 a new position, which is due to the different thickness of the thin flat elements 29A . 29B . 29C , which adhere to the side walls of the wreath 26 connect, is conditional. The waves 20 . 30 and 40 are then screwed back so that the corresponding arms 21 . 22 . 23 in the passages of the corresponding openings on the flat elements and in the corresponding openings on the end faces of the ring 26 be brought back. Practically after the appropriate upper arms 21 . 31 and 41 the stamp carrier 3 leave, these are re-introduced into the corresponding following pairs of openings:

• - 50 with 28A -,
• - 51 with the corresponding opening 28B at the corresponding end face of the wreath 26 -, and
• - 52 with the corresponding opening 28C at the corresponding end face of the wreath 26 ,

By a simple rotation of the waves 20 . 30 and 40 From the respective recordings, this device thus makes it possible to expose the assembly ring-shaped punch as well as the stamp itself and to gain direct access to these in order to be able to attach other intermediate pieces and thus change the end position of the stamp exactly as desired, in particular without that the entire stamp carrier, as in the known solutions from the prior art, must be removed from below.

It will be apparent to one skilled in the art that as the punch position changes as described above, it will be necessary to change the position of the corresponding die equally as well.

For this purpose, a description of a solution is explained below, which essentially follows the same principle and uses the same, associated devices as in the above description to change the stamp position.

It should be understood, however, that in the following description, two alternatives are given to the embodiment, namely: A) In a first case, since the punch is no longer present, the die becomes the centering and adjustment function of the positioning take over (which in the presence of the punch by the wreath 26 is taken over). In this case, the solution is that, the template is easily removed, the corresponding flat elements are set and the die is then reinstalled within the corresponding recess in the die carrier. Therefore, in the following description, no element corresponding to "ring 26" (which is located between the punch carrier and the stamp itself) is mentioned because the adjusting function, as just said, concerns only the die.

In this first case, where only worked on the die and a function of the rim used in the stamp 26 is omitted, the solution corresponds essentially to the one that concerns the stamp. Therefore, only a brief but detailed description of this is given here, since the skilled person is certainly also able, with the help of the corresponding figures, to understand the solution proposed below.

Thus, an element carrying the die becomes 5 shown at the top of a lower tool 7 ( 8A ) and is suitable, in its interior a corresponding die 6 which is adapted to be adjusted in the Matrizenträger so that these from above can be pulled out without the Matrizenträger must be removed.

For this purpose, the Matrizenträger 5 on its lower surface 610 a second recess 611 ( 8B ), which is open at the bottom and formed as a rectangular, preferably a quadrangular base having prism.

• - mehrere einzelne separate zweite Aussparungen 612, 613, 614, die am Matrizenträger angeordnet sind, wobei jede Aussparung sowohl an der unteren Fläche 610, d.h. nach unten, als auch in Richtung auf den unteren Abschnitt der zweiten Vertiefung 611 geöffnet ist, sodass diese angrenzend und offen und kommunizierend mit jeder zweiten Aussparung 612, 613, 614 ist.

According to the present solution, the die carrier also remains in this case 5 at the lower tool 7 firmly. Second adjustment means are arranged to adjust the die position, comprising:

• - Several individual separate second recesses 612 . 613 . 614 which are arranged on the die carrier, wherein each recess on both the lower surface 610 that is, down, as well as toward the lower portion of the second recess 611 open so that it is contiguous and open and communicating with every other recess 612 . 613 . 614 is.

Also in this case, in the figures as well as in the description on a punch carrier with three ( 3 ) Recesses 612 . 613 . 614 Referenced. However, it is understood that the number of recesses can be varied. In this case, for example, two or four recesses can be provided.

Preferably, the recesses 612 . 613 . 614 the surface of the lower tool fitting, because the matrix itself is thereby contained with higher accuracy within the die carrier.

Analogous to the stamp are two of these recesses 612 and 614 arranged on opposite sides of the second recess, the third recess 613 is on the third page of the second recess 611 arranged. (Please refer 8B )

Also in the present case are several second flat elements 629A . 629B . 629c arranged, which at corresponding end faces of the die 6 attached and at the bottom of this are arranged so that these with the corresponding second recesses 612 . 613 . 614 which are arranged inside the matrix itself.

• - sowie mehrere zweite Wellen 620, 630, 640 (8B), welche in den zweiten Durchgangsbohrungen 612A, 613A und 614A parallel zueinander aufgenommen sind,
• - sowie mehrere zweite Arme 621,631, 641, welche in den entsprechenden zweiten Aussparungen 612, 613, 614 enthalten und außen an den entsprechenden zweiten Wellen 620, 630, 640 angebracht sind.

Also in this case, several second through holes 612A . 613A and 614A ( 8th . 9 ) on the ceiling of the second recesses 612 . 613 . 614 and oriented upwards ( 9 ), each through hole through the entire material thickness of the die carrier being parallel to the side walls of the second recess formed as a rectangular prism 611 so go through that these ( 8A . 9 ) on the upper surface of the die 6 opens and is accessible from the outside, ie from above,

• - as well as several second waves 620 . 630 . 640 ( 8B ), which in the second through-holes 612A . 613A and 614A are recorded parallel to each other,
• - And a plurality of second arms 621, 621, 641, which in the corresponding second recesses 612 . 613 . 614 included and outside on the corresponding second waves 620 . 630 . 640 are attached.

Analogous to the description for the punch carrier, the die carrier 5 at the lower portion similar openings, which are referred to here for differentiation from the openings on the punch carrier here as "holes". That means that the corresponding first holes 628 . 629 . 630 advantageous down and thus substantially at the level of the second recesses 612 . 613 . 614 are positioned.

Analogously, the second flat elements 629A . 629B . 629c corresponding second holes 650 . 651 . 652 on which are so dimensioned and arranged that the first holes 628 . 629 . 630 and the second holes 650 . 651 . 652 coincide with each other, with corresponding passages are formed in the corresponding second arms 621, 621, 641 introduced in similar, even constructive and functional as described for the punch carrier same manner and pulled out.

So in this case are the second arms 621 . 631 . 641 arranged and dimensioned so that they can be introduced or pulled out by rotating the corresponding shafts in the corresponding, between the first holes and the second, with the first matching holes located passages.

Preferably, in this case too, the second arms 621, 631, 641 are in each case corresponding to the corresponding second shafts 620 . 630 . 640 orthogonal.

• B) Im zweiten Fall (siehe 8C) wird eine Baugruppe ausgeführt, die ähnlich zur Baugruppe aus 8A ist, jedoch sich davon dadurch unterscheidet, dass ein unterer Kranz 66 vorgesehen wird. Dieser Kranz 66 (der im zuvor beschriebenen Fall A) als Matrize direkt diente) übernimmt hier nur die einzige und eigene, gerade definierte Funktion eines unteren Kranzes 66.

The person skilled in the art will certainly have understood that the function of this die is identical to the description of the wreath 26 is because the matrix 6 structurally equal to the wreath 26 is trained and works in the same way.

• B) In the second case (see 8C ) performs an assembly similar to the assembly 8A is, however, different from that in that a lower wreath 66 is provided. This wreath 66 (which in the above-described case A) served as a die directly) takes over here only the only and own, just defined function of a lower ring 66 ,

Another difference is that the lower wreath 66 is provided that this in its interior a specific template 67 picks up which with an inner bore 68 is provided, which is adapted to the overlying stamp 4 as known from the prior art record.

To summarize and briefly describe: with reference to 8C the assembly shown here is exactly the same as in 8A shown assembly, except that in 8A the matrix 67 will be added. Furthermore, the Matrizenträger 6 out 8A equal to the lower wreath 66 out 8C , To make it clear again, we repeat that both devices 6 and 66 work in different ways, although these may be the same as the device 6 serves as a template while these are in 8A the function of a lower rim 66 takes over, since the function of the matrix already from the element 67 is taken over.

Because these elements 6 e 66 geometric and constructive are the same to the component of the assembly 8C clear and easy to illustrate, below are the components of the assembly 8C with the same numbering, for the virtually same component 8A and 8B is used, marked, with the only difference being that in 8C the numbering for the component 8A a "1" is presented.

Thus, an assembly was executed, the ideal but also partly constructive the same, but symmetrical to the description of the stamp 4 is.

For the sake of brevity, unnecessary explanations of the other remaining parts will be made 8A and waives the corresponding function, since these parts and the corresponding function to those skilled in the art due to the description of in 8th illustrated devices are traceable.
