Fig. 1 is a simplified schematic representation of a press brake 1 is shown, the from a machine frame 2, consisting of side uprights 3, 4, a fixed table bar 5 and a cross-dressing 6 is formed.
a press bar 8 in a plane formed by the table bar 5 level and relative to this adjustable, in the embodiment shown by the side posts 3, 4 immovably arranged drive means 9, 10 a Drive device 11, for example hydraulic cylinder 12 of a hydraulic system 13, is actuated, depending on a hydraulic cylinder 12 is attached to the side posts 3, 4 and hinged to opposite end portions 14 of the adjustable press bar 8 with piston rods 15 and thus two axis positions 16, 17 for the initiation of Forming adjusting forces on the press bar 8.
Such an arrangement is often customary if shorter bending tools 21, 22 deviating from the length 23 are used, which are then positioned eccentrically with respect to a center plane 27 running perpendicular to a contact surface 26 and parallel to the side cheeks 3, 4, For example, if two or more sets of tools consisting of the bending tools 21, 22, the alternation of the press brake 1 are provided for the alternate use.
the drive device 11 comprises the hydraulic system 13 and essentially has a container 28 for a pressure medium, for example hydraulic oil, a pump unit 29, a control unit 30 and corresponding connecting lines for acting on the hydraulic cylinders 12. Further, detection means 32 are provided for the control of the hydraulic system 13, wherein in particular on pressure sensors 33 in the connecting lines 31 is pointed, which are preferably arranged directly on the hydraulic cylinders 12.
the operation of the press brake 1 is controlled and regulated by a control and / or regulating device 34, which essentially comprises a computer 35 with data memory 36 and the correspondingly required switching and control elements 37.
the controller 34 is powered by a power source 38, e.g. a power grid 39, fed via lines 40 with energy and is connected via lines 41 with the controlled and to be supplied with power control, detection and securing means.
the control and / or regulating device 34 comprises a path measuring device 42, by means of which the respective setting position of the adjustable press bar 8 is measured and monitored with respect to a reference position during an adjustment process and used as a variable control parameter in a control program for Verstellweg horrung.
the Wegmessvorraum 42 is formed by an opto-electronic measuring devices which are arranged at the two opposite end portions 14 of the press bar 8 and determine the respective position of the bending beam on arranged on the fixed side walls 3, 4, known from the prior art linear scales 43 and their measurement results are transmitted to the control and / or regulating device 34 and evaluated.
this Wegmessvorraum 42 at the opposite end portions 14 of the press bar 8 thus also allows the determination of the parallelism of the adjustment of the press bar 8 with respect to the table bar 5 and thus the opposing bending tools 21, 22, as well as the determination or monitoring of an angular position, such as it occurs at different displacement of the drive means 9, 10 or to compensate for different springing of the side stand 3, 4 - caused by asymmetric load by eccentric position of the bending tools 21, 22, and connected by different in the axle positions 16, 17 to be introduced adjusting forces - according to Arrows 44,45 - in order to apply them as needed to these deformations.
a distance measuring device 42 can be used as a distance measuring device 42, another known from the prior art device, such as a distance laser.
Dehnmesssensoren 46 arranged on the side posts 3, 4 or piezo elements or laser beam measuring devices integrated in the side cheeks 3,4 are possible.
the load state is directly from the operating state of the drive means 9, 10 and thus from the measured values of the detection means 32, e.g. derive the pressure sensors 33 or in the case of electric drives determined by current measuring means drive power, e.g. to calculate according to predetermined formulas in the computer 35 or to determine by comparison with stored in the data memory 36 models or files.
a hydraulic drive system 50 for the press bar 8 by means of the hydraulic cylinder 12 is shown in a simplified representation, wherein the representation and description is limited to a drive side of a naturally symmetrical provided drive device 11 and independently thereof, of course, depending on the drive side, based on a center plane 27, a plurality of hydraulic cylinders 12, for example four may be provided for the operation of the press bar 8.
the hydraulic drive system 50 preferably forms a central reservoir 28 for the pressure medium and the controllable pump unit 29, from which a pressure line 31 leads to the control valve 30 formed by a proportional control valve 30 via which the hydraulic cylinder 12 via connecting lines 53, 54 depending on Regulation of the proportional control valve 52 in a piston pressure chamber 55 or rod pressure chamber 56 is applied to the medium.
a return line 57 for the return of the medium from the hydraulic cylinder 12, which according to the position of the proportional control valve 52 either with the connecting line 53 which acts on the piston pressure chamber 55, or with the connecting line 54, which acts on the rod pressure chamber 56, fluidly connected.
control components are, for example, connected to the connecting line 53 for the piston pressure chamber 55
Further controls are in the control circuit to the connecting line 54 for the rod pressure chamber 56th provided hold-up valve 60 and a counter-valve 61st
the pressure sensor 33 is provided on the hydraulic cylinder 12.
the movement control of the press bar 8 is effected by the corresponding control of the control arrangement 62 described from the aforementioned valves via the control and regulating device 34.
the valves are preferably provided with electric drives 63, which are connected via lines 64 to the control and / or regulating device 34 are and often a one-sided admission of the valves against the measures provided for in the valve spring assemblies 65, which cause a basic position takes place.
the working stroke - according to arrow 44 - is carried out to minimize the duty cycle in accordance with the specified safety guidelines with different speeds for express, approach and Umformzu ein, the Um Kunststoffen for the speed change by the control program depending on the assembly of the press brake 1, according to the used Bending tools and to be carried out on the workpiece forming part and be indexed via the path measuring device 42.
FIG. 3 the engagement position of the bending tools 21, 22 for forming the circuit board 25 in order to obtain a bending angle 67 predetermined for the work piece 24 is shown in full lines. Due to a material-dependent springback behavior of the board 25 and a real thickness 68 of the board 25, and other factors such as bending radius, tool training, etc., an immersion depth 69 is to be specified, which is greater than a theoretical insertion depth 70 to achieve the bending angle 67.
the adjustment force to be applied during the working stroke - as indicated by arrow 44 - causes a reaction force 71 on the press brake 1 and thus springing of the side cheeks 3, 4 and bending of the press bar 8 - as shown in broken lines on the press bar 8.
This, as well as the springback of the board 24 require a correction of the travel of the press bar 8, a differential path 72 in an effective lower reversing position relative to a theoretically lower reversing position.
This differential path 71 is equal to the dependent of the required forming force springing of the side cheeks 3, 4, the bending or deformation of the table beam 5, press bar 8, bending tools 21, 22 and springing of the board and is thus a correction of the stroke and is preferably stored in a load / deformation matrix in the data memory of the control and / or regulating device and via the parameter of the pressure of the pressure medium, as determined by the pressure sensor 33 during the forming process, the control of the movement of the Press bar 8 basis.
the control of the hydraulic cylinder 12 for pressurizing the rod pressure chamber 56 is carried out to minimize a reaction time after reaching the predetermined target value corresponding to a control ramp of the control function automatically by the permanent detection of the physical parameter by the pressure sensor 33. If this target value is reached, the reversal takes place the hydraulic cylinder 12 on Eilgurhub.
a control process is also possible which is initiated by increasing the pressure in the rod pressure chamber 56 to system pressure, which corresponds to the maximum pressure of the hydraulic drive system 50, in order to generate the largest possible pressure in the piston pressure chamber 55.
This pressure is necessary to obtain a correspondingly large pressure difference at the proportional control valve 63 and thereby to achieve a high but controlled decompression speed.
This process It lasts until the system pressure, which is reduced by the area ratio of the rod-side annular piston surface to the piston surface, has formed in the piston pressure chamber 55. Now, the pressure in the piston pressure chamber 55 along the control ramp of the control function is lowered by means of the proportional control valve 63.
This process is ended when the ambient pressure, preferably approximately 1 to 3 bar, above atmospheric pressure is applied to the pressure sensor 33 as a set value.
the restoring forces arising from the deformations on the machine elements as well as on the bending part on the controlled and controlled pressure reduction in the piston pressure chamber 55 are reduced to a degree to the application of the hydraulic cylinder 12 for a rapid return stroke with simultaneous opening of the Nachsaugventils 58 via the control and / or To make control device 34 without occurrence of shock loads.
the control ramp determined in the control function can be linear, stepped or exponential, wherein preferably an exponential curve of the control ramp is provided.
the method according to the invention also makes it possible to monitor or determine the unloading state by determining the load-dependent unloading stroke via the parameter of the adjusting force to be applied to the drive means 9, 10 for forming the plate 25.
the machine-related deformation files stored in the data memory 36 are used , Bar models, etc., or determined by calculations in the computer 35 according to stored equations of the deformation, consisting of springing of the side stand 3,4, deflection of the press bar 8 and remindfederweg the board 25.
the result thus determined is equal to the discharge stroke for reducing the reaction force and is controllable by means of the path measuring device 45 and can additionally or as a comparison value for the determination of the switching point for the Eil Weghub application.
