    The invention relates to a press brake for bending metal sheets.
    From EP 2 364 789 B1 a press brake is known, which has a tool manipulation device for taking out individual beer tools from a tool holder of the press brake. The tool manipulation device has a carriage, which is displaceably mounted on the press brake in a direction parallel to the bending edge. On the carriage three manipulation arms are arranged, which are designed to accommodate bending tools. By means of the manipulation arms, individual bending tools can be taken out of the tool holder of the upper press bar, thereby enabling a displacement of the individual bending tools in the tool holder of the upper press bar.
    The press brake described in EP 2 364 789 B1 has the tail, that the tool manipulation device is designed only for receiving three bending tools and thus the flexibility of the tool manipulating device is limited.
    The present invention is based on the object to provide a press brake, in which the tool setup times are as short as possible.
    This object of the invention is solved by the features according to claim 1.
    According to the invention, a press brake is designed for bending metal sheets. The press brake comprises a first fixed pressing beam, as well as a second pressing beam displaceable relative thereto; arranged on the press beam or trained tool holders for receiving Biegewerkzeu conditions; a tool storage for storing unused bending tools; a tool changing device, which is designed for insertion of the bending tools in the tool holder and comprises a gripping device for manipulating the bending tool. Furthermore, a tool supply device is formed, which is designed to accommodate a plurality of bending tools and which by means of a drive device between a tooling position, for loading the tool providing device with bending tools from the tool storage, and a tool change position in which the bending tools by means of the tool changing device from the tool providing device in the tool holder are transferable, is displaceable.
    An advantage of the inventive design of the press brake is that the bending tools can be changed in as short a time as possible, so that the set-up of the press brake can be as short as possible and thus the efficiency of the press brake can be as large as possible. In addition, can be achieved by the transport of the bending tools by means of the tool supply device, that the bending tools can be used with a simple as possible tool changing device in the tool holders of the pressing bars.
    Furthermore, it may be expedient if a tool carrier is formed which is designed to receive at least two bending tools simultaneously, wherein the tool carrier can be coupled to the tool providing device and can be accommodated thereon. The advantage here is that a plurality of bending tools can be used in the tooling position in the tool carrier and for this placement process, the tool delivery device need not be positioned in the tooling position. After the placement process of the tool carrier with bending tools, the tool carrier can be picked up by the tool providing device and transported by this position in the tool change.
    Furthermore, it can be provided, a first linear guide is formed, which is arranged on an inner side of the first pressing beam, and second linear guide is formed, which is arranged on an outer side of the first pressing beam, wherein the tool providing device has a portal which the tool holder of the first pressing beam spanned and on which portal a first guide unit of the first linear guide and a second guide unit of the second linear guide is arranged, whereby the tool providing device is displaceable parallel to a bending edge. By this measure, the advantageous effect can be achieved that the tool delivery device can be stably stored on the press brake and thereby can be moved with a high travel speed between the tooling position and tool change position.
    In addition, it may be provided that the drive device comprises a toothed rack, which is arranged on the first pressing beam, wherein a pinion which is coupled to a arranged on the tool providing device positioning motor engages in the rack, whereby the tool providing device is displaceable parallel to a bending edge. The advantage here is that by the drive means of the rack, the tool changing device can have high acceleration values and thus the efficiency of the tool changing device can be increased.
    Also advantageous is an embodiment according to which it can be provided that the toothed rack is arranged on the outside of the first pressing beam. This positioning of the rack can be selected in order to integrate them as well as possible in the bending press.
    According to a development, it is possible that a manipulation device is formed, which is arranged in the region of the tool storage and for manipulating the bending tools and / or the tool carrier between tool storage and tool supply device is used. The advantage here is that the bending tools can be transported in the tool storage by means of the manipulation device of the space provided for the bending tools storage space in the tool delivery device or in the tool carrier.
    Furthermore, it may be expedient for the manipulation device to have a first manipulation arm and a second manipulation arm, a first coupling device being formed on the first manipulation arm and a second coupling device for receiving the tool carrier or the bending tools on the second manipulation arm. By the two manipulation arms of the manipulation device, two of the tool carrier can be picked up by the manipulation device, whereby it is possible for the manipulation device to accommodate a tool carrier located in the tool change position on the first manipulation arm of the manipulation device and already engage on the second manipulation arm of the manipulation device second tool carrier is prepared with to be equipped bending tools in order to use it as quickly as possible in the tool change position can.
    In addition, it can be provided that both manipulation arms have a linear adjustment, by means of which the two coupling devices are independently displaceable in the vertical direction. The advantage here is that the tool holder can be used by this measure in the vertical direction in the tool change position or in the tooling position. In particular, a specific movement of the tool carrier can be achieved by the independent displacement of the coupling devices in order to use the tool carrier in the tool change position or in the tooling position even in tight conditions.
    Furthermore, it can be provided that the tool supply device has a first tool receiving area, which serves for receiving bending tools for the first stationary pressing beam and has a second tool receiving area, which serves for receiving bending tools for the displaceable second pressing beam. The advantage here is that at the same time Bie tools can be added in the tool delivery device both in the first tool receiving area and in the second tool receiving area. Thereby, the performance of the tool changing device can be increased.
    According to a particular embodiment, it is possible that a trained for the specification of Blecheinschubtiefe backgauge device serves as a tool changing device for inserting the bending tools in the tool holder. The advantage here is that the backgauge device which is present on the press brake anyway can be used simultaneously as a tool changing device and thereby the total cost of the press brake can be kept as low as possible.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:
    Fig. 1 is a side view of an embodiment of a processing plant;
    Fig. 2 is a front view of an embodiment of a processing plant;
    3 is a perspective view of an embodiment of a manipulation device;
    Fig. 4 is a perspective view of an embodiment of a tool providing device.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    Fig. 1 shows a schematic representation of the side view of a processing plant 1. The processing plant 1 comprises a press brake 2, which is provided for bending a sheet 3.
    The press brake 2 further comprises a first fixed pressing beam 4, in which a tool holder 5 is formed for receiving a bending tool 6. Furthermore, the press brake 2 comprises a second adjustable pressing beam 7 on which also a tool holder 5 for receiving one of the bending tools 6 is formed.
    The sheet 3 to be bent is inserted for the bending operation between the bending tools 6 of the first 4 and the second pressing beam 7. The bending tool 6, respectively the second pressing beam 7, fixed in the second pressing beam 7 is moved upwards or downwards in the vertical direction by a press drive unit 8. For controlling the press drive unit 8, a computer unit 9 is provided, which can be coupled to an input and / or display unit 10.
    Furthermore, as shown in FIG. 1, it can be provided that the processing installation 1 comprises a gripping device 11 which serves for manipulation of the bending tool 6.
    From Fig. 1 it is further seen that the bending tool 6 has a tool body 12 which deforms the bending sheet 3 to be bent during bending. The bending tool 6 can be positioned in the tool holder 5 in the horizontal displacement direction 13 along the clamping portion of the tool holder 5. For this purpose, the bending tool 6 can be moved laterally in the horizontal direction of displacement 13 in the tool holder 5 of the pressing bars 4 or 7.
    Furthermore, it is also possible that the bending tool 6 is introduced in a vertical direction 14 in the tool holder 5. For this possibility to introduce the bending tool 6 in the tool holder 5, it is necessary that the bending tool 6 has an insertion mechanism.
    In the tool holder 5, a plurality of bending tools 6, which are of similar construction, can be positioned next to one another and connected to one another. Thus, it can be achieved that bending edges 15 of individual bending tools 6 form a correspondingly long machining edge.
    Another possibility for the arrangement of bending tools 6 in the tool holder 5 is that a plurality of different bending tools 6 are positioned in the tool holder 5. These different bending tools 6 are then used for various bending operations and can also be replaced individually. If bending tools 6 of different types are used for different working steps, then it is usual for them to be arranged at a certain distance from each other.
    In order to provide the most flexible processing plant 1 available, it is necessary that the bending tools 6 can be easily and quickly clamped in the tool holder 5 and taken out of this again.
    As can be seen from Fig. 1 it can be provided that the gripping device 11 is arranged on a tool changing device 16. The tool changer 16 may be slidably mounted relative to the press brake 2 at this. In particular, it can be provided that the tool changing device 16 is displaceable in the longitudinal extension 17 of the tool holders 5, wherein the longitudinal extent 17 extends parallel to the horizontal displacement direction 13. Furthermore, it may be provided that the tool changing device 16 has different actuators and thereby the gripping device 11 is displaceable in a plurality of travel directions, for example in three linear directions. The tool changing device 16 can thus be designed as an independent manipulation device by means of which the gripping device 11 can be moved freely.
    In a further embodiment, it can be provided that the gripping device 11 is arranged on a backgauge device 18. Such a backgauge device 18 is installed as standard in a press brake 2 in most cases and serves to the insertion depth of the plate 3 in the
    To limit press brake 2 and thus to determine the bending line on the plate 3. The fact that the backgauge device 18, which is installed as standard in the press brake 2, is used to move the gripping device 11, the overall structure of the press brake 2 can be kept as simple as possible and thus the costs are kept as low as possible.
    It is further provided that a tool providing device 19 is formed, which is mounted on a first linear guide 20. The first linear guide 20 is in this case arranged on the inner side 21 of the first pressing bar 4. Furthermore, a second linear guide 22, which is arranged on an outer side 23 of the first pressing beam 4, is formed on the tool delivery device 19. Characterized in that the first linear guide 20 and the second linear guide 22 are arranged at a distance from each other, the tool changing device 16 may have a high stability.
    Furthermore, it can be provided that the first linear guide 20 comprises a first guide unit 24, which is arranged on the tool supply device 19. In addition, the second linear guide 22 may include a second guide unit 25, which is also arranged on the tool providing device 19.
    The two guide units 24, 25 can be designed in the form of a guide carriage, wherein the first guide unit 24 can interact with a first guide rail 26 and the second guide unit 25 can interact with a second guide rail 27.
    The first guide rail 26 and the second guide rail 27 can each be arranged on one of the pressing beams 4, 7.
    As can further be seen from FIG. 1, it may be provided that a drive device 28 is provided which serves for positioning the tool delivery device 19 in the horizontal displacement direction 13. In particular, it can be provided that the drive device 28 comprises a positioning motor 29, which is accommodated on the tool supply device 19 and on which a pinion 30 is arranged on an output shaft. The pinion 30 may be engaged with a rack 31 fixed to the first pressing bar 4. Thus, the tool providing device 19 can be moved by means of the positioning motor 29 in the longitudinal extension 17 of the tool holders 5.
    Furthermore, it can be seen from FIG. 1 that it can be provided that the tool delivery device 19 has a portal 32 which spans the first press beam 4 between the first linear guide 20 and the second linear guide 22. In addition, it may be provided that the tool supply device 19 has a first tool receiving area 33 and a second tool receiving area 34. In the first tool receiving area 33, bending tools 6 can be accommodated which are provided for use in the first pressing beam 4. In the second tool receiving area 34, bending tools 6 can be accommodated, which are provided for use in the second pressing beam 7. In particular, it can be provided that the tool receiving areas 33, 34 are arranged in the region of the inner side 21 of the first pressing beam 4. The two tool receiving areas 33, 34 can be arranged directly above one another.
    When changing tools can be provided that the bending tools 6 are removed by means of the tool changing device 16, in particular the gripping device 11, from the tool supply device 19 and are inserted into the tool holders 5 of the pressing bars 4, 7. To be able to carry out this tool change process as quickly as possible, it is necessary that the tool delivery device 19 is positioned in the horizontal displacement direction 13 such that the travel paths for the tool changing device 16 are as short as possible. This can be achieved, in particular, by positioning the tool delivery device 19 as close as possible to the final location of the bending tool 6 in the tool holder 5.
    FIG. 2 shows a further and possibly independent embodiment of the processing installation 1 in a schematic view from the front, with the same reference numerals or component designations being used again for the same parts as in the preceding FIG. 1. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIG.
    In Fig. 2 is particularly well seen that it can be provided that the tool delivery device 19 can be moved by means of the drive device 28 in the longitudinal direction 17. The drive device 28 may be configured such that the tool changing device 16 can be displaced over at least the entire length 35 of the tool holder 5. In particular, the rack 31 or the guide rails 26, 27 can extend over the entire length 35 of the tool holder 5.
    In particular, it can also be provided that the rack 31 or the guide rails 26, 27 protrude laterally beyond the length 35 of the tool holders 5 and protrude, for example, into a tool store 36.
    As a result, the tool delivery device 19 can be moved into the region of the tool storage 36, whereby the bending tools 6 can be removed from the tool storage 36 by means of a manipulation device 37 and can be inserted into the tool delivery device 19 as short as possible.
    In a first embodiment, it may be provided that the bending tools 6 are received directly in the tool delivery device 19. In a further embodiment, it can be provided that bending tools 6 are positioned in a tool carrier 38, which can accommodate a plurality of bending tools 6. The tool carrier 38 can be designed in such a way that it can be received together with the bending tools 6 accommodated therein in the tool supply device 19 or alternatively can be removed therefrom.
    Furthermore, it can be provided that the bending tools 6 are prepared and arranged in the tool carrier 38 in the intended order in the area of the tool store 36. This allows the actual setup time at a
    Tool change can be shortened and thus the efficiency of the processing system 1 can be improved. In the tool holder 38, a receiving recess 39 may be provided, in which the bending tools 6 can be added or used.
    In particular, it can be provided that the bending tools 6 can be inserted into or removed from the tool holder 38 by means of the tool changing device 16 or by means of the manipulation device 37 in a prepared tool carrier 38. The tool carrier 38 can be transported between the tool storage 36 and the press brake 2 by means of the tool supply device 19.
    Auserdem can be provided that in the processing plant 1 more tool carrier 38 are present, which can be optionally equipped with bending tools 6. The prepared tool carriers 38, together with the bending tools 6 accommodated therein, can be received in the tool delivery device 19.
    Furthermore, it can be provided that an intermediate storage position for tool carrier 38 is formed in the tool storage 36.
    As can further be seen in FIG. 2, the tool delivery device 19 can be moved between a tool change position 40 and a tool load position 41.
    The tool change position 40 is that position of the tool providing device 19, in which it is in the area of the tool holder 5. If the tool carrier 38 is in its tool change position 40, then the bending tools 6 can be displaced by means of the tool changing device 16 either from the tool supply device 19 or tool carrier 38 into the tool holder 5 or from the tool holder 5 into the tool delivery device 19 or the tool carrier 38.
    The tooling position 41 is the position of the tool supply device 19 in which this or the tool carrier 38 is located in the area of the tool store 36. When the tool providing device 19 is in its tooling position 41, bending tools 6 can be inserted from the tool memory 36 into the tool supply device 19 or the tool carrier 38 by means of the manipulation device 37 or bending tools 6 can be inserted from the tool supply device 19 or the tool carrier 38 into the tool store 36 become. Furthermore, it is also conceivable that as tooling position 41 that position is designated in which the tool holder 38 is stored in the tool memory 36.
    FIG. 3 shows a perspective illustration of a further embodiment of a manipulation device 37, which may be independent of itself, again using the same reference numerals or component designations as in FIG. 1 for the same parts. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding figure 1 or reference.
    As can be seen from FIG. 3, it can be provided that the manipulation device 37 has a base frame 42 on which a manipulation arm receptacle 43 with a first manipulation arm 44 and a second manipulation arm 45 are arranged, the two manipulation arms 44, 45 being designed to receive the tool carriers 38 , In particular, it can be provided that the first manipulation arm 44 has a first coupling device 46, by means of which the tool carrier 38 can be removably received on the first manipulation arm 44. Analogously, it can be provided that the second manipulation arm 45 has a second coupling device 47, by means of which the tool carrier 38 can be removably received on the second manipulation arm 45.
    The two manipulation arms 44, 45 can each have a linear adjustment 48, by means of which the two coupling devices 46, 47 and thereby the tool carriers 38 accommodated on the manipulation arms 44, 45 are displaceable independently of one another in the vertical direction 14. This allows the tool carrier 38 by means of the manipulation arms 44, 45 in the factory
    Stuff delivery device 19 or used in the tool memory 36 and removed from these again.

In particular, bending tools 6, which are provided for the first pressing beam 4, are inserted into the first tool receiving area 33, and bending tools 6, which are provided for the second pressing beam 7, are inserted into the second tool receiving area 34.
    Subsequently, the tool supply device 19 is moved from the tooling position 41 to the tool change position 40.
    In a further method step, the bending tools 6 are then taken out of the tool supply device 19 by means of the tool changing device 16 and inserted into the tool holder 5 of the press brake 2.
    In addition, it is possible for the bending tools 6 located in the tool holders 5 to be taken out of the tool holder 5 by means of the tool changer 16 before and / or after or parallel to this method step and to be deposited in the tool delivery device 19.
    Now, if all old bending tools 6 are removed from the press brake 2 and all new bending tools 6 are inserted into the press brake 2, the tool providing device 19 can be moved from the tool changing position 40 in the tooling position 41.
    There, the bending tools 6 can be removed by means of the manipulation device 37 from the tool supply device 19 and stored in the tool memory 36. Subsequently, the tool-making device 19 can be prepared with new bending tools 6 from the tool memory 36.
    In a further exemplary embodiment, the bending tools 6 are not received directly in the tool supply device 19, but the bending tools 6 are accommodated in a tool carrier 38, which can be received in the tool supply device 19. The tool carrier 38 can be stored together with the bending tools 6 received therein in the tool store 36.
