Definitions
- the present invention relates to an apparatus and a method for forming a sheet, in particular a body or a
- shims which are attached to the support or clamping areas or points of the tools, to effect a discoursekorrektur.
- the invention is based on the object to provide an apparatus and a method for forming a sheet, which reliably enable a correction with little effort during production.
- the object underlying the invention is in an apparatus for forming a sheet according to the invention with the features of independent claim 1 and in a method for forming a sheet according to the invention with the features of independent claim 5 solved.
- Advantageous developments are the subject of the respective dependent claims.
- an apparatus for forming a sheet which is formed with one
- the actuators and consequently the individual support and clamping elements can be adjusted for manual adjustment via the control device as needed without manual intervention. This can be done in an automated manner, with any adjustment measures can be logged at the same time. This simplifies handling and avoids errors.
- control device is formed, a representative for an adjustment adjustment of the orientation and / or position of the support and clamping elements
- Sensor elements can be used as additional and separate means for detecting the state - ie, for example, position and / or orientation - of the respective actuators and / or the support and clamping elements.
- the inventive device for forming a sheet then designed, if according to an advantageous
- control device for interacting with the actuators and is adapted to detect a respective actual orientation and / or actual position of the support and clamping elements.
- the detection of the actual orientation and / or actual position can be effected in each case by sensors integrated in the actuators and / or by a control provided for each actuator, for example a stepping motor or a pneumatic cylinder.
- a particularly reliable form of readjustment results when the control device is operated in the manner of a control loop.
- a device for forming a sheet provided that the control device is arranged to compare a respective actual orientation and / or actual position of the support and clamping elements with a respective desired orientation and / or desired position of the support and clamping elements and on the basis of a result of the comparison for an adjustment adjustment of the orientation and / or position of the support and clamping elements
- the correction signal can consequently form the basis for a readjustment.
- the sheet is formed by clamping under mechanical contact of a plurality of support and clamping elements with the sheet by holding, orienting and / or positioning the support and clamping elements.
- the orientation and / or position of the support and clamping elements are controlled according to the invention for an adjustment adjustment.
- Correction signal is, in particular by actuation of actuators, an adjustment correction of the orientation and / or position of the support and
- Clamping elements with a respective desired orientation and / or desired position of the support and clamping elements is compared. On the basis of a
- Result of the comparison is representative of an adjustment adjustment of the orientation and / or position of the support and clamping elements
- This correction signal generated. This correction signal can then be used as the basis for the subsequent adjustment in the sense of a post-correction.
- Figures 1 to 4 show a schematic side view of an embodiment of the device according to the invention for forming a sheet in different operating states, which are different Phases of an embodiment of the invention
- FIG. 1 shows an embodiment of the device 100 according to the invention for the shape of a metal sheet 1 in a schematic side view in a first embodiment
- the invention of certain devices 100 to form a sheet according to Figure 1 consists of the core of a plurality of support and clamping elements 1 1, 12 and 13, which via actuators 21, 22 and 23 in their position and / or orientation with respect to a to be formed sheet 1 are adjustable and adjustable.
- the actuators 21, 22 and 23 are connected via a control line 20 with a
- the control line 20 can also be regarded as a detection and control line 20, because it can also be configured to from the individual actuators 20, 22 and 23 and the associated support and clamping elements 1 1, 12 and 13, a response to the Control device 10 of the device 100 for evaluation and evaluation of a state of the sheet 1 and / or the arrangement of actuators 21, 22 and 23 and support and clamping elements 1 1, 12 and 13 to deliver.
- the sheet 1 has a top 1 -1 and a bottom 1 -2 and is in the schematic representation of Figure 1 in a plane perpendicular to
- Plane layer arranged arranged.
- the externa ßeren actuators 21 are actuated, so that the first support and clamping elements 1 1 to the top 1 -1 and to the bottom 1 -2 of the sheet 1 are brought to touch this mechanically and between them to fix and fix.
- the arranged between the first support and clamping elements 1 1 section of the sheet 1 is fixed in the manner of a clamping frame, this is necessary for the subsequent shaping processes.
- second support and clamping elements 12 are brought to the top 1 -1 of the sheet 1 that they follow the manner of a base distribution in about a desired shape for the sheet 1 1 -3 '.
- This desired shape 1 -3 'for the sheet 1 to be obtained by the molding process by the apparatus 100 using the proper method is shown in phantom in FIG.
- a third support and clamping element 13 is brought from below to the bottom 1 -2 of the sheet 1 such that the third support and clamping element 13 the
- Bottom 1 -2 of the sheet 1 touched and moves from the rest position indicated in Figure 4 with 1 'up in the direction of the second support and clamping elements 12 to produce an actual shape 1-3 of the sheet 1, the course of the contact points the second and third support and clamping elements 12 and 13 follows or corresponds. Performs a comparison of the actual shape 1 -3 of the sheet 1 to determine a
- Deviation for example, compared to a desired shape 1-4 of the sheet 1, so during the production process, for example in the manufacture of subsequent parts, the control of the third actuator 23 by the
- Control device 10 via the control line 20 cause that by changing the actuation of the third actuator 23, the third support and clamping element 13 is moved to the position indicated in Figure 4 with 13 'position, so that the actual shape 1 -3 the desired shape 1 -4 of the sheet 1 approaches as closely as possible in the subsequent production process.
- Geometry adjustment is possible and a high effort in the determination and documentation of the tool tuning is necessary because both product and tool tolerances must be recorded and determined station-specific.
