Description

The invention relates to a machining tool according to the preamble of claim 1. Such a machining tool is eg in the DE-A-2719122 disclosed.

The invention further relates to a system of a punching machine and a machining tool according to the preamble of claim 12. Such a system is eg in the GB-A-2130132 disclosed.

With such a processing tool for a punching machine, in particular forming operations on sheets can be performed flexibly.

There are known processing tools for the forming of sheets, in particular for an introduction of beads, gills, Kneifkonturen and embossments, which have a rigid, or relatively inflexible structure. In particular, for different large-scale forming several individual tools are manufactured, which then occupy each one tool space in the tool magazine in the punching machine.

This requires either an enlargement of the tool magazine or an increased set-up effort, since the tools must be replaced again and again.

In addition, if a different forming operation is carried out, for example, another bead or gill is produced, another pattern is formed, or different pinching contours are produced, again and again a replacement of the tools is required, which causes an increase in non-productive times and thus slows down the workflow and uneconomical power. On the other hand, from the document FR 2,847,836 a press known in a machine frame two rotatable about a horizontal axis receiving body for receiving a plurality of tool elements having. The tool elements are attached to outer surfaces of the receiving body.

document US-A-2558616 discloses a striking marker having a marking wheel as a receiving body having outer surface portions to which symbols of atomic numbers are attached. The marking wheel is rotatably arranged in a carrier in a direction perpendicular to a direction of impact of the outer surface portions.

In the document WO 2004/080649 A1 a working head for a machining center is disclosed. The working head has on a circumference of a horizontally pivotable body tool holders for example drill or end mill.

document DE-A-27 19 122 shows a device for marking industrial products with embossed areas on the circumference of horizontally rotatably mounted embossing stamps. The dies are each driven via a linearly driven pawl which engage in a ratchet wheel on the respective stamp.

It is therefore an object of the invention to provide a machining tool with which the workflow can be optimized, whereby use of the tool magazine is improved and non-productive times are reduced.

The object is achieved by a machining tool according to claim 1 and a system according to claim 12. Further developments of the invention are the subject of the dependent claims.

By providing at least two tool elements on a receiving body, which is rotatable about a rotation axis, the direction of which is different from a vertical direction, in a receptacle, a plurality of different forming tool elements can be provided in only one tool. Due to the non-vertical rotatable mounting of the tool elements, the tool is not enlarged beyond its usual size. In addition, the Umformwerkzeugelemente can be changed by simply rotating the receiving body without the complete tool must be replaced.

The invention will now be explained by means of embodiments with the aid of the attached figures.

Further embodiments of the receiving body with different cross-sections.

Fig. 1 shows a punching machine 1 as an application example of a sheet metal working machine. Another application example is, for example, a combined punching / laser cutting machine.

The punching machine 1 has a C-frame 2 as an essential part. The C-frame 2 is formed by a torsionally rigid welded steel construction. At the rear end of the C-frame 2, a hydraulic unit 3 is arranged as an energy source for punching movements.

Furthermore, the punching machine 1 has a machine control device, not shown, which is connected to all the actuators of the punching machine 1 and controls the actuators.

On the lower inside of the C-frame 2, a workpiece support 4 in the form of a machine table for placing a workpiece is provided. The workpiece is here a plate-shaped Sheet 10, but may for example be a plate made of a plastic or other suitable material.

On the machine table is a workpiece moving device 5, the u.a. a guide and a cross rail with clamping claws for gripping and moving the sheet 10 on the workpiece support means 4, is provided.

At the front end of the upper leg of the C-frame 2, a plunger 6 is provided with a plunger control 7. By the plunger control 7, the plunger 6 is controlled so that it can be stopped in the region of its stroke in a Z-direction in any position, and thus any position in the Z-direction can be approached.

In the plunger 6 is an upper tool holder 8 for receiving an upper part of a punching tool and other tools, such as. of forming tools, provided.

At the front end of the lower leg of the C-frame 2 is a lower tool holder 9 for receiving a lower part of punching tools or other tools, such. B. of forming tools provided.

In operation, the sheet 10 is positioned for a machining operation by the workpiece moving means 5, the gripped sheet 10 moves in an X-direction and a Y-direction. In this case, the sheet 10 slides in the X direction on the machine table and is moved in the Y direction together with the machine table. The machining process, eg a forming process, is triggered after the positioning of the sheet 10, so that the point of the sheet 10 to be machined is located at a defined position in the region of the forming tool. The plunger 6 moves down to a predetermined maximum or other defined stroke and shapes the sheet 10 in a desired manner. Then, the plunger 6 moves back up to an upper position and the sheet 10 is repositioned for the next machining operation. The punching machine 1 further has a drive 11 for the upper tool holder 8, with which the tool holder 8 can be rotated about a Z-axis 12 of the plunger 6. The upper tool holder 8 can be rotated at any angle about the Z-axis 12 and fixed in this position.

In the upper tool holder 8, a machining tool 13 can be received, with which the sheet 10 is machined from above. For special functions within the machining tool 13, a rotary drive 14 is provided for the tool 13.

Fig. 2 shows a non-inventive embodiment of the machining tool 13 for machining the sheet 10. The machining tool 13 has a tool shank 15 with which the tool 13 can be positively and play-free recorded in the upper tool holder 8.

Furthermore, the machining tool 13 has a receptacle 16 which is connected to the tool shaft 15. In the receptacle 16, a receiving body 17 is rotatably mounted about an axis of rotation 18. The rotation axis 18 is arranged horizontally in the punching machine 1 in the installed state of the machining tool 13 in the first embodiment. The receiving body 17 is rotatable about the axis of rotation 18 by means of a rotary wheel 19 as drive means. Optionally locking means are provided to detect the receiving body 17 in the desired positions and thereby prevent it from twisting.

The receiving body 17 is for receiving in Fig. 3a and Fig. 3b shown by way of example, in a first embodiment integrated therein, tool elements 20 are provided. The tool elements 20 are provided for processing the sheet 10 and are used primarily for forming the sheet 10, in particular for making beads or gills or as embossing and pinching tools.

Fig. 3a and Fig. 3b show the receiving body 17 in two different orientations. In Fig. 3a In the orientation of the receiving body 17 shown, the tool element 20.1 is shown on the underside. The tool element 20.1 is used for impressing knob-like depressions.

In Fig. 3b the receiving body 17 is shown rotated about the axis of rotation 18 by 180 °, so that the tool element 20.1 is now located at the top and the tool element 20.2 is arranged on the underside. The tool element 20.2 is used to memorize the term "MultiTool".

The receiving body 17 can be rotated by means of the rotary wheel 19 so that either the tool element 20.1 or the tool element 20.2 is located on the underside of the machining tool 13, which faces the sheet 10 to be processed.

The receiving body 17 has circumferentially at different locations, here at the top and at the bottom, outer surface portions on which the tool elements 20 are fixable. In alternative embodiments, however, the receiving body 17 may also be designed such that even more surfaces are provided for fastening the tool elements 20, so that a polygon results in the direction of the axis 18.

The tool elements 20 may, as in the first embodiment be integrated in the receiving body 17, or be attached to the receiving body 17 by alternative mounting options.

An attachment possibility is the provision of threads in the receiving body 17, wherein the tool elements 20 then have holes, via which they are fastened by means of screws to the receiving body 17. An alternative embodiment is the fastening of the tool elements 20 by means of a magnet on the receiving body 17. Also alternatively or additionally clamping devices are possible, with which the tool elements 20 are clamped to the receiving body 17.

In an in Fig. 4a and Fig. 4b In the embodiment shown, the receiving body 17 has a receiving contour 21 on one side. The receiving contour 21 is in Fig. 4a and 4b shown in cross-section perpendicular to the axis of rotation 18. The receiving contour 21 is not closed and forms an opening 22 which extends along the axis of rotation 18. The opening 22 is directed toward a radially outer surface of the receiving body 17. Laterally from the opening 22, webs directed toward the opening 22 are formed on the radially outer surface of the receiving body and form undercuts, resulting in a T-slot. The undercuts can alternatively be formed by other elements, so that, for example, results in a dovetail groove. In Fig. 4a the receiving contour 21 is formed so that it has the undercuts into which the tool elements 20, as in Fig. 4b shown, are insertable. An outer contour 23 of the tool element 20 is designed such that it is complementary to the receiving contour 21 of the receiving body 17. Through the opening 22, a region of the inserted tool element 20 is exposed. In the Fig. 4a and Fig. 4b shown Undercut 24 causes the outer contour 23 of the tool elements 20 and the receiving contour 21 of the receiving body 17 form a form fit, which fixes the tool element 20.

In alternative embodiments, the outer contour 23 of the tool elements 20 need not necessarily be complementary to the receiving contour 21, in particular if the tool elements 20 by fastening methods such as screwing, magnet, o.ä. are attached.

As in Fig. 5 shown, the tool elements 20 need not necessarily consist of a single part, but can also be composed of several tool elements 20.3 and 20.4. These tool elements 20.3 and 20.4 are inserted and secured in this embodiment in the receiving body 17, wherein here are the outer contours of the tool elements 20 and the receiving contours 21 are complementary.

In the FIGS. 6a and 6b a further embodiment of the machining tool 13 is shown. In addition to the first embodiment, according to the invention, the second embodiment of the machining tool 13 has a sprocket 25. The ring gear 25 is rotatably provided on the machining tool 13 so that it can rotate about a rotation axis 26 of the machining tool. The ring gear 25 has a first tooth profile 28 which is engaged with a bevel gear 27 which is attached to the receiving body 17. Turning the ring gear 25 about the axis of rotation 26 causes the receiving body 17 is rotated about its axis of rotation 18.

The sprocket 25 has a second tooth profile 38, with the in Fig. 1 shown rotary drive 14 is engaged. By turning the rotary drive 14, the ring gear 25 is rotated, whereby then the receiving body 17 is rotated (see Fig. 6b ). The desired orientation of the receiving body 17 about the Z-axis is thus achieved by a coordinated rotation of the drive 11, which rotates the upper tool holder 8 and thus the machining tool 13, and the rotary drive 14, which rotates the ring gear 25. The receiving body 17 is thereby rotated so that the desired tool element 20 is in a horizontal position on one side of the receiving body 17, which is opposite to the workpiece to be machined.

That in the Fig. 7a and Fig. 7b shown machining tool 13 according to the second embodiment is provided on the receiving body 17 with tool elements 20 which is provided for forming the sheet in the form of beads. Alternatively, the machining tool 13 may be provided according to the first embodiment. The machining tool 13 is here designed so that it is intended to be received in the upper tool holder 8.

Denoted by the reference numeral 39, a counter tool to the machining tool 13 is shown, wherein the counter tool 39 can be received in the lower tool holder 9. The counter tool 39 has a tool element 40 complementary to the tool element 20 of the machining tool 13. The receiving body 17 is rotatable about an axis 41 of the counter tool 39. A rotation mechanism corresponds in principle to that of the machining tool 13. The axis 41 is, like the axis of rotation 18, arranged horizontally in the installed state.

In Fig. 8a a third embodiment of the receiving body 17 is shown. In one embodiment of an axle pin 29, a first disc 30 and one or more second disc (s) 31 form the receiving body 17 here. These discs 30, 31 have in contrast to the embodiments of the receiving body 17 shown above in the direction of the axis 18 seen a hexagonal shape. The discs 30 and 31 are arranged coaxially with each other and each have a means by which the two discs 30, 31 are non-rotatably mounted to each other on the axle 29 can be attached. The axle pin 29 has in the present case a spring 34 and the discs 30, 31 have a central opening 37 which has a plurality of grooves 32. Thus, a kind of tongue and groove connection between the discs 30, 31 and the axle 29 is formed. The device may alternatively be formed by a pivot pin, wherein the cross section of the axle pin is not circular, and with a disc having a complementary to the cross section of the axle bolt opening.

The first disc 30 and the second discs 31 are, as in FIG Fig. 8b shown mounted on a further embodiment of the axle 29. The difference between the two embodiments of the axle pin 29 is that the spring 34 is interrupted along the axle pin 29 in the further embodiment. A cutout 42 resulting from the interruption is so wide along the axle pin 29 that it corresponds at least to the width of one of the disks 30, 31. If the discs 30, 31 are displaced on the axle 29 so that they are located on the cutout 42, the discs 30, 31 can be rotated relative to the axle 29 without completely removing the discs 30, 31 from the axle pin 29. Alternatively, a plurality of recesses 42 may be present. These are then arranged so that the discs 30, 31 are not in their deferred working position on the recesses 42, so that they then do not twist.

Such an arrangement, in which the number of grooves 32 corresponds to the number of side surfaces 33, may also be so are that, as shown, six side surfaces 33 are present, but ten side surfaces 33 are present. In this case, a tool element 20 with a number from 0 to 9 can be attached to each of the side surfaces 33 of a disk 30, 31, so that a continuous number for marking a batch or the like. can be embossed. The grooves 32 are here complementary to a spring 34 on the axle pin 29 and the discs 30, 31 can each be so twisted plugged that each result in flat side surfaces along the axis 18.

A fourth and fifth embodiment of the receiving body is in Fig. 9 and the Figures 10a and 10b shown. This essentially corresponds to the one in Fig. 8a and 8b shown embodiment, in which a plurality of side surfaces 33 can be strung together in various combinations. In this embodiment, the first disc 30 is connected to the axle 29 so as to be non-rotatable thereto. The disc 30 and the disc 31 each have a device by which the two discs 30, 31 are non-rotatably attachable to each other. The disc 30 has a protruding molding 35, here in the form of a pin. As in Fig. 9 2, the second disc 31 has a plurality of through openings 36 complementary to the protruding molding 35 in a side surface (fourth embodiment). Alternatively, the disk 31, as in FIG 10a and 10b Shown indentations 43, which do not go completely through the discs 31, in one of the side surfaces of the disc 31 opposite to the protruding molding 35 (fifth embodiment).

At the in Fig. 9 shown embodiment, a plurality of discs 31 by a fitting 35 (pin) are non-rotatable to each other and to the disc 30. In an alternative to the in 10a and 10b In the embodiment shown, the shaped pieces and depressions 43 can also be arranged on the outer circumference.

The number of complementary openings 36 again corresponds to the number of side surfaces, and the projecting mold piece and the complementary openings 36 are each arranged so that the side surfaces 33 are plugged together to form a flat surface. The second and the further discs 31 are rotatable about the axle 29.

The advantage of this embodiment is that to rotate the discs 30, 31 relative to each other, the discs 31 need not be completely disassembled from the axle 29. Here, the disc 31 must be moved with the openings 36 only by the length of the protruding mold 35 until the mold 35 is no longer engaged with the opening 36. Then, the disc 31 can be rotated relative to the disc 30 and then the mold 35 are brought by moving the disc 31 back into engagement with one of the openings 36, whereby the side surfaces 33 then form a flat surface again. With too long fittings 35 (pins), however, eliminates the advantage that the discs do not need to be completely dismantled.

Fig. 11 shows a third embodiment of the machining tool 13 with a sixth embodiment of the receiving body 17th

The processing tool 13 here also has the punch shaft 15 for receiving the processing tool 13 in one of the tool holders 8, 9 and the punch holder 16. Other recording options are alternatively possible. In the punch holder 16 of this embodiment, in contrast to the foregoing embodiments of the machining tool 13, the receiving body 17 rotatably supported so that it is rotatable about the rotation axis 18, which is not horizontal, and whose direction does not correspond to a vertical direction. The direction of the axis of rotation thus encloses with a vertical direction an angle α which is greater than 0 ° and less than 90 °.

The dimensions of the diameter of the receiving body 17 and the dimension in the direction of the axis of rotation 18 are compared to the preceding embodiments of the receiving body 17, so that the diameter is relatively large here and the dimension in the direction of the axis of rotation 18 is relatively small. Thus, a disc-like receiving body 17 results.

Due to the relatively large diameter, a large number of tool elements 20 can be fixed on the circumference of the receiving body 17. However, a large diameter of the receiving body 17 means that when the axis of rotation is oriented, for example, horizontally or vertically, the dimensions of the machining tool 13 must also be increased in order to accommodate the receiving body 17. Thus, the orientation of the axis of rotation 18 at an angle of greater than 0 ° and less than 90 ° to the vertical direction results in the possibility of fixing a larger number of tool elements 20 on the receiving body 17, without significantly increasing the machining tool. In this embodiment, the angle is 45 °, although other angles are alternatively possible.

The receiving body 17, as in a previous embodiment, the bevel gear (gear) 27 as a drive device which is in engagement with the tooth profile 28 of the ring gear 25. Alternatively, a rotary knob 19 is possible to rotate the receiving body 17.

The sprocket 25 also has here the second tooth profile 38, with the in Fig. 1 shown rotary drive 14 is engaged. By turning the rotary drive 14 of the ring gear 25 is set in rotation, whereby then the receiving body 17 is rotated here. The desired orientation of the receiving body 17 about the Z-axis is thus achieved by a coordinated rotation of the drive 11, which rotates the upper tool holder 8 and thus the machining tool 13, and the rotary drive 14, which rotates the ring gear 25. The receiving body 17 is thereby rotated so that the desired tool element 20 is in a horizontal position on a portion of the receiving body 17, which is opposite to the workpiece to be machined.

Optionally, there is also the possibility that the receiving body, comparable to the in FIGS. 8 to 10 shown embodiments, consists of a plurality of discs which are coupled to each other.

The two tool elements 20 are integrated in the receiving body 17. Alternatively, the tool elements 20 can be received in a receiving contour described above. The tool elements 20 then also have along the axis of rotation 18 an exposed area. The entire circumference of the receiving body 17 may alternatively be provided with a plurality of tool elements 20. Optionally, the tool elements 20 have an outer contour that is complementary to the receiving contour, wherein, if necessary, an undercut of the receiving contour in the direction of the radial outer surface of the receiving body 17 forms a positive connection with the tool elements 20. The tool elements 20 can, as described above, be attached to the receiving body 17 in various ways. The tool elements 20 are also in this embodiment shown forming tools. Alternatively, it is also possible to provide pinching tools. In the tool holder 8, 9, the tool holder 8, 9, in which the machining tool 13 is received, opposite, then a counter tool is received, which optionally also has rotatable counter tool elements.

In Fig. 12 Further embodiments of the receiving body 17 are shown. Alternatively, triangular cross-sections (a), square cross sections with tool elements 20 on all side surfaces (b) (in contrast to those in FIGS FIGS. 3 to 6 shown embodiments, which have only two opposite tool elements 20) or rectangular (not square) cross sections are used. The tool members 20 are provided on the wide side surfaces (or alternatively on the narrow side surfaces).

In operation, the machining tool 13 is received in a known manner from a tool magazine of the punching machine 1 in the upper tool holder 8. In alternative embodiments, the tool can also be received in the lower tool holder 9, but this must be provided according to the upper tool holder 8 described here with the corresponding drives 11, 14.

The metal sheet 10 is subsequently moved under the upper tool holder 8 in such a way that the desired region of the metal sheet 10 to be formed is arranged below the tool 13. The upper tool holder 8 with the machining tool 13 is then rotated by means of the drive 11 so that the machining tool 13 has the desired orientation with respect to the sheet 10. At the same time or offset in time, the rotary drive 14 rotates the ring gear 25 by a predetermined angle, so that, tuned with the rotation of the machining tool 13, the desired tool element 20 is arranged on the underside of the receiving body 17, that is opposite to the workpiece to be machined. Subsequently, a triggered by the plunger control 7 stroke of the plunger 6 is carried out, so that the desired forming process of the sheet 10 is performed. Thereafter, the plunger 6 moves with the machining tool 13 back up and the plate 10 is moved accordingly, so that the next area can be edited. The relationship, ie the coordination, between the angle of rotation of the machining tool 13 about the Z-axis 12 of the plunger 6, and a twisting angle that must be performed by the rotary drive 14 to arrange the desired tool element 20 on the underside of the tool 17 is stored in the engine control device or is calculated by the engine control device.

In the first non-inventive embodiment of the machining tool 13, the orientation of the receiving body 17 is made by manually rotating the rotary wheel 19. In order to prevent unwanted twisting, a locking device may be provided.
