    Description: The present invention relates to a holding device for receiving at least one tool for punching, cutting or punching, with at least one receiving opening for holding a tool. Further, the invention relates to a tool for this holding device and to a method for grinding and positioning of this tool.
    In particular, it is a Hafteeinrichtung for receiving a tool, that is, a punch or a die for a punching device or the like, as used for example in sheet metal processing. Generally, however, wherever material separation by shearing takes place. In the process, the material is ultimately torn by a cutting edge.
    The quality of the punching, or the cut, is essentially determined by the quality, namely by the state of wear of the tool, ie the punch and / or the die. For this reason, holding devices are used in which the punch or the die are releasably held. The respective tool can thus be either replaced or reground. The latter means, for example, in the case of an approximately cylindrical. Stamp, however, that this is shortened by material ablation in its longitudinal axis. It goes without saying that this is possible only to a very limited extent and is only very limited repeatable. As a result, the length of this punch and thus the position of its relevant for the punching cutting edge is changed. An adjustment of the position of the tool, in the present case of the punch, by appropriate locking devices is only time-consuming and / or inaccurate possible in the prior art.
    On the basis of these findings, the invention has the object to provide a holding device for receiving at least one tool for punching, cutting or punching, which allows both a regrinding and an accurate vertical positioning of this tool in a simple manner. Next, a suitable for this holding device tool and a new method for grinding and positioning of this tool should be specified. The tool should be held positionally variable but secured against unintentional vertical movements.
    The inventive holding device corresponds to the characterizing features of claim 1. The tool is apparent from claim 7 and the method for grinding and positioning of claim 10. Further advantageous embodiments of the inventive concept can be seen from the dependent claims.
    Hereinafter, preferred embodiments of the invention will be described in more detail with reference to the schematic drawing. Shown are only the essential components.
    Fig. 1 shows a holding device in section;
    Fig. 2 shows the same holding device in section along the line A-A in Fig. 1;
    Fig. 3-4 show the holding device according to Figures 1 and 2 with the tool in different positions.
    Fig. 5-9 show various components of a holding device according to the invention;
    Figs. 10-11 show two examples of tools for mounting in the holder.
    The holding device 1 is intended for releasably receiving a tool 2. In the present example, it is a stamp, as it is typically used in punching. The holding device 1 has an actual holder 3, which is provided with a receiving opening 4 for the tool 2. Usually, such receiving openings 4 are designed as a bore. At the pressing direction 5 opposite end 6, the tool 2 is locked by a cover 7.
    The receiving opening 4 of the holding device 1 is stepped according to FIG. 1. It has, in the drawing above, to the pressing direction 5 opposite end 6 out, a first section 8 with a larger cross section and the pressing direction 5 through a second section 9 with respect to the first section 8 of smaller cross-section. In the longitudinal section, that is, in the direction of the aligned in the pressing direction 5 axis B - B, stored in longitudinal section approximately T-shaped tool 2. That is, the tool 2 has a shaft 10 and a head 11 opposite this wider.
    The exact shape of the head 11 of the tool 2 is not relevant in itself. It is essential, however, that above the shaft 10 is a cross-sectional widening. And the head 11 of the tool 2 is dimensioned in each case so that its height 12 is smaller than the height 13 of the first section 8 wider cross section of the receiving opening 4 of the holding device 1. Or vice versa, the said section 8 is higher than the head 11. Consider both in the direction of the mentioned axis BB.
    The difference between these two heights 12 and 13, so the remaining height 14 of the first section 8 wider cross-section of the receiving opening 4, is filled with a plurality of spacers 15. The spacers 15 are formed in the present example as O-rings, as shown in particular in FIG. 2, which shows a section along the line A-A in Fig. 1. The spacers 15 thus have an inner opening. The outer diameter D of the spacers 15 is smaller than the inner cross section of the first portion 8 of the receiving opening 4. The inner diameter d, ie the cross section of the inner opening, is greater than the cross section of the shaft 10 of the male tool 2. The inner diameter d can approximately the cross section of second section 9 with a smaller cross section of the receiving opening 4 correspond. That is, the spacers 15 are dimensioned so that they fit on the one hand in the said first portion 8 of the receiving opening, on the other hand, at least partially engage around the shaft 10 of the tool 2.
    For the sake of simplicity, five spacers 15 are shown in the drawings. In fact, there may be fewer or, more meaningfully, more than five spacers 15, for example eight. Finally, the number is also dependent on the selected thickness of the spacers 15.
    The meaning of the inventive construction will be apparent, if one considers the respective arrangement of the spacers 15 in Figs.
    In Fig. 1, all spacers 15 are arranged below the head 11 of the tool 2 about its shaft 10. This is the starting position when a new tool 2, here a stamp, is inserted and put into use. In this arrangement, the spacers 15 cause the tool 2 to be set back the furthest relative to the pressing direction 5, with the head 11 resting on the cover 7 of the holding device 1 in this illustration.
    During the work process, the tool 2 will be dull at its lying in the pressing direction 5 end 16 with currently by wear. In particular along the punching, cutting or punching edges. Once this wear has progressed so far that a regrinding of the tool 2 is required, this can be done in a technically known manner. The shaft 10 is thereby shortened shallow and move the end 16 closer to the head 11.
    The previous problem to find the resulting from this reduction, new position of the tool 2 in the holding device 1, is achieved in a simple manner by repositioning individual spacers 15. Specifically, the shaft 10 is ground to a measure corresponding to the thickness of a spacer 15 and compensated for a spacer 15 from its original position below the head 11 and instead inserted above the head 11, ie in the space between the head 11 and the lid. 7 After renewed placement of the cover 7, the tool 2 is again held vertically immovably in the holding device 1. And that in exactly the required, new position along the aligned in the pressing direction 5 axis B-B. Any time-consuming and error-prone measuring and adjusting the position of the tool 2 is eliminated.
    In the position shown in FIG. 3, in this example, five spacers 15, the shaft 10 has already been shortened by a Mass 17, or ground, which corresponds to the thickness of three spacers 15. Consequently, there are now three spacers 15 above the head 11 of the tool 2, while two are still below, around the shaft 10. This tool 2 can therefore be sanded twice again accordingly.
    In contrast to the starting position shown in FIG. 1, the tool 2 is in the representation of FIG. 4 in the last possible position. All spacers 15 are now inserted above the head 11. The shank 10 of the tool 2 has been shortened by the maximum possible dimension 17. For renewed signs of wear, the tool 2 must be replaced. However, this is very easy after removing the lid 7. All spacers 15 are placed below the head 11 of the new tool 2 and the lid 7 is replaced. Also, the new tool 2 is now, without special considerations and in particular without measurement and adjustment work exactly positioned in its initial position along the aligned in the pressing direction 5 axis B-B. If necessary, it can then be looped or shortened as often as required, in accordance with the number of spacers 15 provided.
    However, the grinding or shortening of the shank 10 of the tool 2 could, if necessary, also take place by more than the thickness of a single spacer 15, for example by an amount equal to the thickness of two or more spacers 15 ,
    From the other drawing figures 5 to 9, the various components he inventive holding device 1 can be seen, with Figs. 5 to 7 show the actual holder 3 and Figs. 8 to 9 the lid 7. According to this solution, the holder. 3 and the cover 7 can be connected by means of two screws, the corresponding screw holes being visible. Of course, the holding device 1 may also comprise connecting means for its attachment to a processing machine. For example, a punching machine or the like. These connecting means may in turn be screw holes and screws.
    The inventive holding device 1 can, if appropriate, with a corresponding change in mass and proportions, are designed to accommodate tools 2 for punching, cutting or punching of any kind. As can be seen, for example, from FIGS. 10 and 11, the respective tool 2 can have different lengths and geometries.
    In general, it is within the scope of the invention according to claim 1, the holding device 1 in detail form differently than shown in the purely schematic drawing.
