    In Fig. 1 is a control and regulating device 1, which is communicatively connected to a control and monitoring device 2 of a bending press 3, shown.
    The bending press 3 is shown in simplified form and has a stationary press bar 4 with a bending tool 5 and a relative thereto with a drive means 6 of a drive assembly 7 adjustable press bar 8, which is also equipped with a bending tool 9 on. The drive means 6 for the adjustment of the press bar 8 is according to the embodiment shown, a hydraulic cylinder 10 which is acted upon via a hydraulic system 11 with a pressure medium. Of course, other drive arrangements 7, such as, for example, an electromotive spindle drive, eccentric drive, etc., are also possible for driving the press bar 8.
    The control of the hydraulic system 11, or an electric drive via the control and monitoring device 2 according to a proposed forming process for a workpiece 12 predetermined control program, which is manually started and called by an operator via the control and regulating device 1, wherein about the operation and by the formation of the control and regulating device 1, a manual influence on the control process is provided, as described later in detail.
    After the retrieval of an adjustment cycle for forming the inserted between the bending tools 5, 9 workpiece part 12, starting from an upper end position 13 of the press bar 8, the adjustment in a lower end position 14 in the Bregewerkzeug 9 of the adjustable press bar 8 in the bending tool 5 of the fixed press bar 4 dips to an intended immersion depth while the work piece 12 is formed angularly, after which a return stroke takes place in the upper end position 13. N2010 / 23400 -6-
    The lower end position 14 is dependent on the tool geometry of the bending tools 5, 9, an intended Abkantwinkel 15 and is controlled by the program for the workpiece 12 and for example via a connected to the control and monitoring device 2 Wegmesssystem 16.
    The adjustment of the press bar 8 with the tool 9 over its total stroke between the upper end position 13 and the lower end position 14 is divided into a control Eilhubbereich 17, with a tool tip 18 is set to a distance 19 to a top 20 of Werkstückst 12, an Anstellhub 21, after which the tool tip 18 impinges on the upper side 20 of the workpiece 12 and a Umformhub 22, in which the tool tip 18 is immersed by an immersion depth 23 in a V-shaped Matrizenöffnung 24, and thus the lower end position 14 is reached.
    Starting from the lower end position 14 is also a controlled return stroke of the press bar 8, possibly after a discharge stroke and subsequent return stroke to the upper end position 13, whereby a Verstelizyklus is completed.
    The adjustment cycle is started or triggered according to the embodiment shown on the connected to the control and monitoring device 2 and actuated by a foot 25 of an operator not shown control and regulating device 1, in the immediate operating area of the bending press 3 on a footprint 26 and ergonomically positioned for the operating force on a footprint 26 and is stored movable.
    Likewise, however, it is also possible to arrange the control and regulating device 1 directly on a front side of the stationary press bar 4 of the bending press 3, for example on a linearly adjustable slide, in order to position it ergonomically in its position to the respective working position of the operating force.
    The control and regulating device 1, according to the embodiment shown, a aufgehbares on the footprint 26 protective housing 27 with a bottom plate 28 and a housing upper part 29, in which an access opening 30 is provided for the foot 25 of the operating force.
    In the interior of the housing upper part 29, a pedal-like adjusting element 32 is pivotally mounted on the bottom plate 28 in a pivot bearing arrangement 31, which via the access opening 30 for the operation with the foot 25 in a tilted position by the N2010 / 23400-7- kung a spring arrangement 33 against a stop means 34, for example a web of the housing upper part 29, is positioned in the inclined position in a first end position 35.
    Starting from this end position 35, the actuator 32 by applying a force - as indicated by arrow 36 - by the foot 25 by an angle 37 against the action of the spring assembly 33, preferably with progressive spring characteristic, against another arranged in the upper housing 29 stop means 38, in a further end position 39 pivotable.
    In the protective housing 27, a movement profile detecting means 40, for example, on the bottom plate 28, attached, which is formed by a linear potentiometer 41 according to the embodiment shown. Via an actuator 42, the pivoting movement of the actuating element 32 is transmitted to the linear potentiometer 41 for outputting a control signal to the control and monitoring device.
    The control signal is, for example, a current signal at an inductive voltage signal or at a capacitive motion profile detection means 40.
    Further, in the protective housing 29, there is provided with the motion profile detecting means 40, e.g. the linear potentiometer 41 line-connected logic module 45 with a processor 46 and a detection and Auswerteschaitung 47 arranged. The logic module 45 is connected for example via a line 48 to the control and monitoring device 2 of the bending press 3. Of course, a wireless communication link, e.g. Radio, light, etc., be provided.
    The pivoting movement of the actuating element 32 about a pivot axis 49 is transmitted via the actuating drive 42, for example a joint connection as a mechanical coupling, to an actuator 50 of the linear potentiometer 41 to deliver a position-related control signal corresponding to the position of the actuating element 32.
    The end positions 35, 39 is in each case assigned a control signal for a stop position of the press bar 8, wherein the end position 35 corresponds to the starting position of the press bar, so the upper end position 13 and the end position 39 corresponds to an emergency stop for a safety stop in the the press bar 8 is set to either stand still in the current position or reversed to return to its upper end position 13. N2010 / 23400 -8-
    By the output from the movement profile detecting means 40 and the linear potentiometer 41 control signal at a deflection of the actuator 32 by applying an adjusting - according to arrow 36 - from its end position 35 in the direction of the other end position 39, the forming cycle via the logic module 45 to the processor 46 and the detection and evaluation circuit 47 passed to the control and monitoring device 2 and started the movement of the adjustable press bar 8 according to the stored program specifications for the corresponding forming process.
    Of course, instead of the described linear potentiometer 41, an incremental linear displacement measuring system 40 may also be used as motion profile detection means 40.
    The adjustment cycle for a forming stroke and return stroke of the adjustable press beam will now be explained in more detail with reference to the diagram shown in FIG.
    The diagram shows in full lines the displacement speed of the press bar, e.g. [mm / s], in the individual stroke ranges, e.g. [mm], again, as deposited, for example, for a specific forming process on a work piece in a data storage of the control and monitoring device of the press brake.
    The adjustment ranges are, as already described for Fig. 1, essentially starting from the upper end position 13 of the press bar 8 - the Eilhubbereich 17, in which the tool tip 18 of the bending tool 9 by adjusting the press bar 8 at a relatively high adjustment speed V1 [mm / s ] is moved to the distance 19 from the top 20 of the workpiece 12 to be formed, wherein the distance 19 represents a predetermined safety distance to be avoided by the injury of the operator in case of improper operation; - This is followed by a Anstellhub 52 of the tool tip 18 of the bending tool 9 with greatly reduced Verstellgeschwindigkeit V2 [mm {s] until placing the tool tip 18 on the upper side 20 of the workpiece 12; - After placing the tool tip 18 on the upper side 20 of the workpiece 12, the actual Umformhub 22 with optionally against the Anstellhub 52 again increased adjustment speed V3 [mm / s] until reaching the immersion depth 23, which of a tool geometry, workpiece thickness, the N2010 / 23400 -9- Φ * • ItM «• * • * • V • • • • k •« * 4 4 i > · · · · · · · · · «* * * * * Μ | * 4 • * * * * * * given bending angle and any material parameters is dependent, and what the end position 14, also called reversal point is reached; - From the so-called. Reversal, or the achievement of the lower end position 14, a return stroke 53 of the press bar 8 at a relatively high speed V4 [mm / s] until reaching the upper end position 13th
    The return stroke 53 may be a discharge stroke to a relaxation of the bending press and the workpiece, so-called. Return springs to achieve, this being essential for an angle control, and thus for a control of the forming quality with an angle measurement method.
    As shown in broken lines in FIG. 3 is a manual speed control of the adjustment of the press bar 8 for predetermined adjustment, in particular for the range of rapid stroke 17, the return stroke 53 and 22 Umformhubes on the position of the control element 32 make.
    In these areas, the predetermined adjustment speed "V" [mm / s] of the press bar 8 can be manually increased as a function of the position of the control element 32 in order to reduce the cycle time.
    This is implemented by means of the position-dependent control signals of the movement profiler 40 and of the detection and evaluation circuit 47 of the logic module 45. The control and regulating device 1 and the movement profile detection means 40 continue to receive a control signal when the end position 39 of the control element 32 is reached the control and monitoring device 2 generates the one, causes emergency stop.
    It is advantageously provided that in order to reach the end position 39 of the actuator 32, an increased resistance to resistance, e.g. is to be overcome by a pivoting movement of the actuating element counteracting braking means, whereby the operator is the end of the control range for the adjustment speed is displayed.
    The emergency stop can on the one hand lead to a stoppage of the further movement sequence, wherein the position reached when the signal of the press bar 9 is either maintained or reversed to return 53 and the press bar 9 is returned to its upper end position 13, N2010 / 23400 -10 -
    As a further function of the control and regulating device 1 with the movement profile detecting means 40 and the detection and evaluation circuit 47 of the logic module 45 is provided that caused by a startle reaction of the operator in a dangerous condition, in the intuitively loaded the actuator 32 in the direction of the end position is, from the position-dependent control signal of the motion profile detection means 40 change the Steuerungssigna !, eg Amperage, voltage, etc, relative to a unit of time, e.g. [ms], so a control curve to detect the acceleration of the adjustment of the control element 32 in the detection and evaluation circuit 40 as an actual value and to compare with a predetermined acceleration threshold and at a predetermined acceleration threshold value exceeded by the actual value to generate a signal for an emergency stop regardless of the instantaneous position of the actuating element and thus to stop the adjustment movement of the press bar 3.
    The operation of the emergency stop is immediately, regardless of the instantaneous position of the actuator 32, upon detection of exceeding the threshold, activated - wherein the Stelibereich assigned position or displacement-dependent speed control for the adjustment movement of the press bar is disabled. This leads to a momentary stoppage of the press bar without significant lag.
    FIG. 4 shows a simplified illustration of the control and regulating device 1 and, on the basis of the diagram shown in FIG. 5, a possible control process for a manual speed control in the predetermined stroke ranges, as previously defined, is explained.
    According to this embodiment, in the end positions (35, 39) of the pedal-like adjusting element 32, switching means 55, e.g. Limit switch 56, proximity switch etc. arranged at the contact by the actuator 32, a stop signal for the adjustment of the press bar not shown is delivered.
    In an adjustment range 57 in the angle 37 between the end positions (35, 39) by actuation of the actuating element via the movement profile detecting means 40, e.g. the linear potentiometer 41, with progressive angular position - according to arrow 58 - control signals for the manual speed control in the predetermined stroke ranges, which are detected by the not shown displacement measuring system, with increasing signal strength, eg. as current "I", or voltage at capacitive N2010 / 23400 - 11 - · · ί * ·· φ · * * • · * · ι »· · ι * * * * φ * φ · Ι · + • · ·· · «· * ·
    Detection means, to the logic module 45 with the detection and evaluation circuit 47 and as control signals to the communicatively connected to the logic module 45 control and monitoring! Direction 2 of the bending press 3 delivered.
    In the diagram - Fig. 5 - is a possible sequence of movements of an adjusting movement of the adjusting element wherein the curve of a control curve 59 of a signal strength of the movement profile detecting means 40 with increasing angular position of the actuating element 32 reproduces.
    As a control parameter further in the detection and evaluation circuit 47, a threshold value for a specified maximum acceleration - as a curve slope line 60 with the pitch angle 61 in the diagram - Fig. 5 - refer, deposited.
    When the threshold is exceeded, e.g. in a shock reaction of the operator - point 62 - in the event of a dangerous situation in which intuitively the actuator 32 is abruptly moved by applying an actuation force - as indicated by arrow 36 - and thus the predetermined threshold is exceeded, as shown by the corresponding to the changed in broken lines Curve - according to 63 - for the acceleration "B"; and a resulting pitch line 64 having a pitch angle 65 shown in the diagram, an emergency stop control signal is generated in the detection and evaluation circuit 47 and sent to the control and controi leinrichtung 2 of the press brake and stopped the adjustment of the press bar immediately ,
    FIG. 6 shows a further embodiment of the control and regulating device 1 in a plan view of a partial area with the protective housing 27 open.
    In the protective housing 27, the pedal-like actuator 32 is pivotally mounted about the pivot axis 49 of a pivot bearing assembly 66 and the spring assembly 33 in an angularly inclined position, as already described above, aligned and pivotable against the force of the spring assembly 33 in the direction of the bottom plate 28.
    In alignment with the pivot axis 49, the motion profile detecting means 40, a rotary potentiometer 68 is disposed in the protective housing 27, which is bewegungsgekuppelt with a Achssiummel 67 of the pivot bearing assembly 66.
    By means of the rotary potentiometer 68, which via a line 69 with the logic module 45 to the processor 46 and the detection and evaluation circuit 47 according to the N2010 / 23400 - 12-
