    The invention relates to a production device, in particular a press brake, for the conversion of workpieces and a method for AusrQsten such Fertigungsernrichturtg with bending tools according to the features in the preambles of claims 1 and 17.
    Manufacturing facilities such as press brakes for forming workpieces made of sheet metal have two parallel aligned pressing bars, which are usually equipped with a plurality of paired bending tools. For forming a workpiece, the two pressing beams are adjusted or guided in a direction perpendicular to their longitudinal direction. A case arranged between the bending tools workpiece is reshaped by the type of such successive pressing against each other of the bending tools. The press beams usually have a tool receiving device formed by a groove into which the bending tools can be inserted and fixed therein. Corresponding bending tools - also referred to as a die on the one hand and a male die on the other hand - are to be arranged at a certain position along the longitudinal extension of the pressing bars or aligned with each other. For the execution of a sequence of different forming processes, the type of bending tools and their position (position of a tool station) are defined in a so-called setup plan of a bending program. On the basis of the set-up plan, the preparation of the production device is then carried out by an operator, in which the bending tools are fastened at the corresponding positions on the pressing bars. It must also be ensured that mutually corresponding bending tools (female and male) are aligned as exactly as possible. This also called 25 14:32:05 12-01-2012 & / 31 • z -2- Preparing the production equipment is usually associated with a correspondingly high working wall.
    It is therefore an object of the invention to simplify the preparatory setup process of a production device of the type described or to reduce the time required for this purpose.
    The object of the invention is achieved by a manufacturing device for forming workpieces made of sheet metal with two parallel aligned pressing beams, which are adjustable by means of a drive device in a direction perpendicular to the longitudinal extent of the pressing beam direction relative to each other. The press beams can be bestickickbar with a variable number of bending tools, the bending tools are arranged in rows along the length of the press beams. The production device furthermore has a control device connected to the drive device for influencing the operating behavior of the production device and a positioning means for determining the position of the bending tools relative to the longitudinal extension of the pressing beam. The positioning means includes a rangefinder based on the use of acoustic or electromagnetic waves. This has the advantage of a particularly flexible feasibility of the setup process and also that the bending tools themselves need not have separate and specially designed facilities for their accurate positioning.
    The embodiment according to which the rangefinder has a beam direction which is equipped in parallel with respect to the longitudinal extension of the press beams, has the advantage that in this way the respective position can be determined directly by the value of the distance in the longitudinal extent of the press beams.
    The developments of the production device, according to which the positioning means comprises a holding device for the rangefinder, wherein the holding device with the rangefinder in a direction perpendicular to the longitudinal extent of the pressing beam direction and is vertically adjustable or after which the holding device with the rangefinder in a direction perpendicular to the Längserstre- 25 14:32:47 12-01-2012 7/31 -3 direction of the pressing beam direction and is horizontally adjustable, has the advantage of a secure adjustment for reliable position detection.
    The design, according to which the positioning means comprises a housing with an adapter and the adapter is designed for attachment to a groove-shaped tool receiving device of the pressing bars, allows application of the positioning means also in production facilities in which previously had to be made purely manual manual setup and positioning of the bending tools.
    The design of the manufacturing device, according to which the positioning means comprises a laser rangefinder, allows a high accuracy in the position detection.
    Due to the design of the production device, according to which the control device comprises an evaluation unit for an actual value of a distance of the bending tool measured by the rangefinder, or according to which the production device comprises a signal device for indicating a deviation of the actual value from a desired value of the distance, has the advantage that the operator is completely relieved of corresponding manually made measurements or evaluations
    The further development of the production device, according to which the signal device is formed by the screen, allows the display of the deviations to be able to output in the most diverse ways of representation.
    According to a further development of the production device, provision is made for the positioning means to comprise a camera which is arranged on the holding device in the region of the rangefinder, the optical axis of the camera being aligned parallel to the beam direction of the rangefinder.
    This has the advantage that the setting of the rangefinder can be simultaneously controlled to the operator terminal and observed on the screen of the operator terminal. -4. 25 -4. 25 B / Jl

    According to a development of the production device is also provided that the bending tools have on its end face a suitable for identification of the bending tool marking. This allows the use of additional automated controls and thus avoiding errors when loading or inserting the bending tools in the manufacturing facility.
    The object of the invention is also achieved independently by a method for equipping a production device with bending tools, wherein in a first step, a first bending tool is attached to a pressing beam and the rangefinder of the positioning means is aligned with the end face of the bending tool and wherein the beam direction of the rangefinder is aligned parallel to the longitudinal extent of the press beam. With the rangefinder an actual value of the distance of the bending tool is measured and determined by the evaluation unit, a deviation of the actual value of a desired value of the distance. The deviation is indicated by a signaling device and the position of the bending tool is changed until the reaching of the desired value of the distance from the signaling device is indicated.
    The development of the method, according to which the alignment of the rangefinder on the end face of the bending tool is performed by a motorized adjustment of the positioning means and in response to inputs to a cooperating with the control terminal operator terminal, has the advantage of a simple and time-saving operation.
    By the further measures, according to which the desired values of the distances are loaded into the control device with the bending tools as an electronic data record before the start of the finishing, has the advantage that the corresponding desired values of the distances only have to be selected and an erroneous input, as can be done when entering individual numerical values, is largely avoided. 25 14:34:08 12-01-2012 s IS i

    According to a further development of the method, it is provided as an additional measure that a tolerance range for a permissible deviation of the actual value from the nominal value of the distance is entered for consideration in the evaluation unit on the operator terminal. This has the advantage that different requirements for manufacturing tolerances of products can be taken into account.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    Stand side walls 6,7 are acted upon by a pressure medium bare actuators 25, 26 of the drive assembly 27, formed of double-acting hydraulic cylinders 28, respectively. Actuators 29, e.g. Piston rods of the hydraulic cylinders 28, are connected to the in Fqhrungsanordnungen 30 of the machine frame 5 in a direction perpendicular to the working plane 14 perpendicularly mounted press beam 16 via pivot bearings 31 and e.g. Bolt 32 drivingly connected. The press beam 15 and the press beam 16 extend over the length 17 approximately symmetrically and in the direction perpendicular to the center plane 12, wherein the length 17 is slightly larger than the distance 11.
    On facing and parallel to the working plane 14 parallel end surfaces 33,34 have the press beams 15,16 tool receiving devices 35 for supporting and releasable attachment of bending tools 36,37.
    As known from the prior art, these bending tools 36, 37 generally form a bending die 39 designed as a die 38 and a bending punch 41 designed as a patri-ze 40. From the state of the art, it is also known to subdivide the bending tools 36, 37 into sections, which results in an easy variability for a tool length 42, in order to be able to adapt these to the respective requirements or also to the conversion of the production device 1 or the Exchange of bending tools 36, 37 easier to make.
    The tool receiving devices 35 in the press beams 15,16 are on the one hand designed for releasably securing the bending tools 36, 37, on the other hand, they form support surfaces 43 for transmitting the bending forces - as indicated by arrow 44 ~.
    As can also be seen from FIG. 1, the production device 1 has a positioning means 45 for determining a position of the bending tools 36, 37. The Positionierungsmittei 45 allows an accompanying measurement of the positions of the bending tools 36,37 during the setup of the production device 1 by an operator. That is, after arranging one of the bending tools 36 on the pressing beam 15 or after arranging one of the bending tools 25 14:36:11 12-01-2012 25 12 / J1
    On the pressing bar 16, the positioning means 45 measures its relative position with respect to a longitudinal extent 46 of the pressing bar 15 or a longitudinal extent 47 of the pressing bar 16.
    FIG. 2 shows a frontal view of the production device 1 according to FIG. 1 with the positioning means 45 arranged laterally on the machine frame 5. According to this exemplary embodiment, the positioning means 45 comprises a laser descent meter 48 with a radiation transmitter 49 and a radiation receiver 50. the beam transmitter 49 has a beam direction 51 which can be aligned with an end face 52 of a first bending tool 36 facing the laser removal meter 48. Preferably, the beam direction 51 of the Laserentfemungsmesser 48 is aligned parallel to the longitudinal extent 46 of the lower press beam 15 and parallel to the longitudinal extent 47 of the upper Blask 16. As can be seen more clearly from FIG. 3 described below, the radiation transmitter 49 and the radiation receiver 50 of the laser rangefinder 48 are fastened to a holding device 53. The holding device 53 is in turn adjustably mounted in a housing 54 of the positioning means 45, so that the Laserentfemungsmesser 48 can be transferred from a position in which the beam direction 51 is aligned with the end face 52 of the bending tool 36 in the lower pressing beam 15 in a position in which the beam direction 51 is aligned with an end face 55 of the bending tool 37 in the upper pressing beam 16. The last-mentioned position of the laser removing blade 48 is indicated by dashed lines.
    Fig. 3 shows a side view of the manufacturing device 1 according to FIG. 2 with the Pnsitinnipri ingsmittel 45 attached thereto for fixing a Pocitron of the bending tools 36, 37. The positioning means 45 is arranged by means of its housing 54 on the machine frame 5. The holding device 54 for the laser removal meter 53 is formed in the shape of a protruding arm, protruding out of the housing 54. Einein provided in the housing 54 mechanism (not shown) on which the holding device 53 is mounted, this can in the vertical direction - according to double arrow 56 25 14:36:54 12-01-2012 13/31
    -9-- adjusted and fixed in different positions. According to an alternative embodiment of the positioning means 45, the holding device 53 may be designed to be pivotable. The adjustment of the holding device 53 with the Laserentfemungsmesser 48 can be done by manual movement and fixation of the holding device 53. Preferably, in the housing 54 of the positioning means 45 for this purpose, a servomotor is provided (not shown), so that the movement and fixing can also be automated.
    The mounting of the holding device 53 in the housing 54 of the positioning means 45 may additionally be designed such that an adjustment of the holding device 53 and the Laserentfemungsmessers 48 also in the horizontal direction - according to double arrow 57 - can be done. This allows an even more accurate adjustment of the Laserentfemungsmessers 48 and the beam direction 51 in an aligned with the bending tools 36,37 and mitderWerkzeugaufnahmevorrichtung 35 position.
    In addition to a drive device 58 and a control device 59, the production device 1 also has an operator terminal 60. In addition to an input device 61, the operating terminal 60 usually also has a screen 62 with which, for example, machining programs can be graphically displayed.
    According to the invention, it is provided that the positioning means 45 or its laser removal meter 48 can be operated via the control device 59 or the operating terminal 60. Like the operating terminal 60, the positioning means 45 is also conductively connected to the control device 59 for this purpose. The control device 59 is equipped with an evaluation unit 63 preferably formed by a software. A value of a distance 64 of the end face 52, 55 of the bending tool 36, 37 is measured by the laser removal meter 48 as an actual value and a comparison with a preselected desired value of the distance 64 can be carried out in the evaluation unit 63. The evaluation unit 63 is further configured to indicate a deviation of the actual value from the nominal value of the distance 64 with the aid of a signal device 65. The display device 1-2012 through the signaling device 65 may be formed by an optical or an acoustic but also by a combination of optical or acoustic display.
    With the thus formed manufacturing device 1, the insertion and positioning of the bending tools 36,37 can now be carried out in accordance with a Rüstplan or bending program by an operator in a simple manner. This will be explained in more detail with reference to FIG. 2. First, a first bending tool 36 is inserted into the lower pressing beam 15 by the operator, and the laser removing blade 48 is adjusted by moving the engagement device 53 so that its beam direction 51 is aligned with the end surface 52 of the bending tool 36. After entering the value of the distance 64 on the operating terminal 60 and starting the measuring process, the laser rangefinder detects an actual value of the distance 64, the evaluation unit 63 determines the presence of a possible deviation of the actual value from the desired value and the operator indicated by the signaling device 65. After starting the measuring operation, the actual value of the distance 64 is continuously recorded, as well as a corresponding evaluation with the evaluation unit 63. The operator can now change the position of the bending tool 36 until the signal device 65 matches it. Value with the preselected desired value of the distance 64 is signaled. Subsequently, a new value of the distance 64 corresponding to its position can be input to the operating terminal 60 for a second bending tool 36, and the second bending tool 36 (shown in dashed lines) can be positioned in the tool receiving device 35. An optionally existing deviation of the actual value of the new distance 64 from the desired value is displayed to the operator by the signal device 65 and the operator can
    Change the position of the second bending tool 36 until the desired value of the distance 64 is reached or is signaled by the signaling device 65. This procedure is repeated for all further bending tools 36 until the taut setup plan provided bending tools 36 are positioned according to the tool length 42 and fixed in the tool receiving device 35.
    25 14:38:21 12-UI-2UI2 13/3 I
    The insertion and fixing of the bending tools 37 on the upper pressing bar 16 can be carried out in the same way as for the bending tools 36 on the lower pressing bars 15. For this purpose, first the Laserentfemungsmesser 48 is aligned by raising the Haitevorrichtung 53 in an area in the Strahlhchtung 51 of the laser rangefinder 48 on the end face 55 of the bending tools 37 The insertion, positioning and fixing of the tools 37 on the upper beam 16 is carried out analogously as in the case of Bending tools 36 of the lower Pressbaikens 15 by the insertion and positioning of the bending tools 36 in the sequence starting with the largest value of the distance 64 to each next smaller value of the distance 64 is advanced.
    The respective values of the distance 64 for the individual bending tools 37 can be predefined by inputting the respective individual values with the aid of the input device 64 of the operating terminal 60. Preferably, the values of the distance 64 are loaded into the control device 59 as an electronic data record with the setup plan or bending program. In this case, when the production device 1 is being set up with the bending tools 36, 37, the operator can select the individual values of the distances 64 on the operating terminal 60, so that individual input of individual values is not required.
    When deviations of the actual values from the respective nominal values of the distance 64 by the signaling device 65 are displayed, it is provided that different signals are used for exceeding, exceeding and the match of the actual value and the required nominal value. This can be realized for example by light signals of different color or acoustic signals of different pitch or signal sequence. Alternatively, however, it is also possible that the deviation of the actual value from the target value of the distance 64 is output to the screen 62 by displaying a corresponding numerical value.
    By using corresponding values for the distances 64 of the end face 52, 55 of mutually associated bending tools 36, 37 during their positioning, it is possible to ensure that the bending tools 36, 37 are aligned exactly with one another. 25 14:39:05 12-01-2012 25 10/31 -12-
    FIG. 4 shows a further embodiment of the production device 1, which is possibly independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 3. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 3 or reference.
    Pie Fig. 4 shows a detail of the manufacturing device 1 with the positioning means 45 according to a further embodiment. The positioning means 45 has, in addition to the Laserentfemungsmesser48 additionally a camera 66 which is also arranged on the holding device 53 in the region of the Laserentfemungsmessers 48 An optical axis 67 of the camera 66 is preferably aligned parallel to the beam direction 52 of the laser rangefinder 48. According to this embodiment, the adjustment of the holding device 53 with the Laserentfemungsmesser 48 is motor-driven and can be controlled by the operating terminal 60 from. An image recorded by the camera 66 can be displayed on the screen 62 of the operating terminal 60 and it is thus possible for an operator, by appropriate control on the control terminal 60, the readjustment of the laser rangefinder 48 on the end face 52 of the bending tool 36 on the one hand or on the end face On the other hand, it is particularly easy to carry out 55 of the bending tool 37.
    According to a preferred embodiment variant, the bending tools 36, 37 have at their end faces 52, 55 individual markings by which they are identified. These markings may also be detected by the camera 66 and displayed on the screen 62 of the operator terminal 60. This allows an additional control of the correct placement of the manufacturing device 1 with the bending tools 36, 37th
    According to a further preferred embodiment variant of the production device 1, the markings on the end faces 52, 55 of the bending tools 36, 37 are displayed by an evaluation software provided in the control device 59. 14: 39: 4 / U-üwu i / 13 l * * · · * * ι * * * * ι · · * - * * «· ··· I» · * -13-automatically detected. For this purpose, the markings may be formed, for example, by barcodes.
    5 shows a further embodiment of the manufacturing device 1 with an alternative embodiment of the positioning means 45. According to this embodiment, the housing 54 of the positioning means 45 has an adapter 68 which is designed such that it on the Werkzeugaufnahmevorrich-device 35 of the press beam 15th or of the press bar 16 can be attached. The positioning means 45 formed in this way can thus also be positioned or fixed to the production device 1 on the pressing beam 15, 16 only as needed, that is, only for the duration of the actual setting-up process. With the adjustable holding device 53 of the Laserentfemungsmessers 48 this in turn between a position in which the beam direction 51 is aligned with the end face 52 of the bending tool 36 and a position in which the beam direction 51 is aligned with the end face 55 of the bending tool 37 be moved back and forth. As in the case of the embodiment according to FIGS. 1 to 4, the positioning means 45 according to the exemplary embodiment according to FIG. 5 can also be controlled centrally by an operator from the operating terminal 60. The positioning means 45 is connected to its power supply to the drive device 58 and for data exchange with the control device 59 via corresponding lines. The measurement of the positions of the bending tools 36, 37 that accompanies the setup process of the production device 1 can again take place in the same way as described above with reference to FIGS. 1 to 4.
    As described above, the distance measurement or the measurement of the distances 64 is carried out with the positioning means 45 using electromagnetic radiation, that is in this case using the laser rangefinder 48. Instead of electromagnetic radiation but also other suitable for non-contact distance measurement physical phenomena , such as ultrasound, find use. In particular, the distance measurement can be carried out according to the principle of transit time measurement of the electromagnetic or acoustic waves. 25 14:40:31 delete 13 i

    Since, for practical reasons, an exact match of an actual value with a desired value can never be achieved, a tolerance range of a maximum permissible deviation for the actual value of the distance 64 is taken into account in the evaluation by the evaluation unit 63. For example, a uniform tolerance level of +/- 1 mm could be specified for all values of the distance 64. As well as the determination of the desired values of the distances 64 in the setup plan, the specification of tolerance ranges in the setup plan can also be provided. Depending on the requirement for the accuracy of the relative alignment of mutually associated bending tools 36, 37, the respective tool stations can individually be given different tolerance ranges. For example, a tolerance range of +/- 1 mm can be set for a first tool station and a tolerance range of +/- 0.5 mm for another tool station, etc. Alternatively, however, it is also possible for the operator to set tolerance ranges for permissible deviations entered at the loading terminal 60 and these are taken into account by the evaluation unit 63.
