Description

The present invention relates to tool machines and methods for machining plate features, preferably sheet metal.

Such tool machines are known from European Patent No. 2527058. This publication discloses a tool machine in the form of a pressurizer for machining the feature, allowing the upper tool to move in and out of the stroke axis with respect to the feature to be machined. It is provided in a stroke device. A lower tool located in the stroke axis and on the lower side facing the upper tool is provided. The stroke drive device for the stroke movement of the upper tool is controlled by the wedge gear. A stroke drive with an upper tool placed on it is motor driven across the positioning shaft. The lower tool then moves synchronously with the upper tool.

From German Patent Application Publication No. 10200780698, an apparatus for performing a method for optical pre-adjustment of a tool, such as a punching tool having a warehouse for receiving the tool, is known. In addition, the spare device includes a receiving unit for detecting the shape of the tool for comparing the detected data with the planning data stored in the computer. It is envisioned that the tools to be inspected or adjusted then are removed from the spare equipment warehouse and fed to the tool receivers that are rotatable and assigned to the length measuring and positioning devices. After pre-adjusting the tool, it is necessary that the tool be removed from the warehouse of the spare device and supplied to the warehouse of the tool machine, from which the tool can be introduced for machining.

From European Patent Application Publication No. 2165784, devices and methods for automatic centering of upper and lower tool holders of punching machines are known. It is intended that the detection means be placed in the upper tool holder, which is subsequently assigned to the lower tool holder. Subsequently, rotation of the detecting means formed as a touch sensor for detecting the deviation of the lower tool holder in the X and / or Y directions occurs. After the detection for automatic centering of the tool receiver is complete, the detection means is returned to the punching machine warehouse again, followed by alignment of the upper tool receiver. Subsequently, the tools intended for the machining stage are removed from the warehouse for the next machining.

It is an object of the present invention to propose a tool machine and a method for processing a plate-shaped workpiece, which is a sheet metal, in which the preparation time is reduced by them.

This problem is solved by a tool machine for machining plate-shaped workpieces, which are preferably sheet metal. It is movable along the stroke axis in the direction of the workpiece to be machined by the upper tool by the stroke drive and vice versa, along the upper positioning axis extending perpendicular to the stroke axis by at least one motor drive. Includes top tools that can be positioned. It further includes a lower tool that is oriented to the upper tool and can be positioned along a lower positioning axis oriented perpendicular to the stroke axis of the upper tool by at least one motor drive. The upper and lower tools are movable within the frame of the machine frame. By control the motor drive can be controlled for the movement of the upper and / or lower tools. At that time, the movement of the upper tool along the upper positioning axis and the movement of the lower tool along the lower positioning axis can be controlled independently of each other. Further, the upper drive unit is provided with a measuring device oriented to at least one lower drive device, and / or the lower drive device is provided with a measuring device oriented to at least one upper drive device. Due to the placement and positioning of at least one measuring device in the lower and / or upper drive, the respective parameters of the upper and / or lower tool, eg tools, are used with at least one measuring device prior to the introduction of the tool for machining. It becomes possible to detect the length and / or the tool shape. Since these data can be transferred to the control of the tool machine and processed, it is realized by the current data of the tool directly followed by the machining of the workpiece. Traditional complex data transfer and subsequent refitting of the rear tool machine by individual measurements of tool length and / or tool type or shape performed in a spare unit separate from the tool machine is no longer necessary. ..

It is contemplated that preferably at least one measuring device is located in the upper and / or lower drive device in close proximity to the tool holder of the upper tool and / or the lower tool. This requires only a small amount of reverse movement of the upper and / or lower tools along the upper and / or lower positioning axis to position the upper and lower tools with respect to the facing measuring device. Make it possible. After the detection of at least one parameter of the upper tool and / or the lower tool, the machining of the workpiece may be started directly following it.

It is preferably contemplated that at least one measuring device will be oriented to the lower tool at the upper drive and / or at least one measuring device will be oriented to the upper tool at the lower drive. Relative movement of the upper and / or lower tool along the upper and / or lower positioning axis may be determined depending on the orientation of the measuring device to the upper and / or lower tool.

It is preferably contemplated that the measuring axis of the measuring device is oriented in the same direction as the positioning axis of the facing upper and / or lower tool. It may be possible, for example, to inspect the height of the machining tool of the upper tool or the counter tool of the lower tool by a simple method. Similarly, the height of the scraper or the presence of the scraper and the type of scraper can be inspected. It is also possible to check whether the length and / or contour of the machining tool of the upper tool or the counter tool of the lower tool is before or beyond the wear limit.

A further preferred embodiment of the tool machine is intended to form at least one measuring device as a touch member or by a non-contact sensor. In particular, non-contact sensors can improve flexibility in parameter detection. Further, no movement along at least one stroke axis is required, and it is sufficient to orient the upper and / or lower tools to the facing non-contact sensors.

Advantageously, the measuring device formed as a non-contact sensor is formed as an optical distance sensor, particularly a line laser or a camera device, particularly a CCD camera. The choice of measuring device may be made according to the available installation space. In addition, the measuring device may meet the required measurement task.

A further advantageous embodiment of the tool machine contemplates that the measuring device is provided on the bracket carriage of the lower drive. This allows for easy positioning close to the lower tool of the measuring device. Moreover, it can be freely oriented towards the top tool with respect to the measurement axis.

At least one measuring device of the upper drive is preferably provided on the double wedge of the wedge gear. This allows for a particularly protective arrangement against the corrugated sheet to be machined.

A further preferred embodiment of the tool machine is intended to assign a removable cover or shield for the measuring process to the outlet side of the measuring shaft near the measuring device. This may provide protection against contamination and / or damage, especially in optical measuring instruments. Such can be uncovered, removed or opened for each measurement task.

The subject of the present invention is more preferably solved by a method for machining a plate-like workpiece that is a sheet metal, in which case the orientation of the workpiece to be machined by the upper tool by the stroke drive along the stroke axis. The upper tool, which is movable in and in the opposite direction, is moved by at least one motor drive along the upper positioning axis extending perpendicular to the stroke axis, and the lower tool oriented to the upper tool is driven by at least one motor. The device moves along a lower positioning axis that is oriented perpendicular to the stroke axis of the upper tool. The upper and lower tools are then moved inside the frame of the machine frame. The motor drive for the movement of the upper and lower tools is controlled by control. The measuring device then oriented towards the lower drive provided in at least one upper drive is aligned with the upper positioning device and / or into at least one lower drive oriented towards the upper drive. It is contemplated that the provided measuring devices can be controlled independently of each other along the lower positioning axis. This allows for a short travel path for positioning the upper tool to the measuring device provided in the lower drive or the lower tool to the measuring device provided in the upper drive, followed by the upper and / / by the measuring method. Alternatively, each parameter of the lower tool can be detected. Since the detection of this parameter can be transferred directly to the control of the tool machine, the detected data of the upper and / or lower tools can be taken into account during subsequent machining steps. This simplifies the equipment process and saves time. This can ensure that the upper and / or lower tools required for subsequent machining steps are received in the upper and / or lower tool holder of the tool machine.

It is even more preferred that the movement of the upper and / or lower tools along the lower and / or upper positioning axis be controlled in duplicate with rotation around the stroke axis and / or stroke movement along the stroke axis. Will be done. This can improve flexibility in implementing the measurement method.

A preferred embodiment of the method contemplates that the height of the upper or lower tool is detected by crossing the measuring axes of the facing measuring devices by moving along the upper and / or lower positioning axes. Such movement allows, for example, the height of the tool body of the upper tool or the counter tool body of the lower tool. Further, the shape and, in some cases, the wear of the tool body or the counter tool body can be detected.

A further preferred embodiment of the method is to position the upper or lower tool close to the measuring axis of the facing measuring device for performing the measurement of the upper or lower tool, or to subsequently perform the measurement strategy. Intended to be axially oriented. In this embodiment of the method, detection of detailed tool information can be performed.

It is further preferred that the data detected by the measuring device is processed in the evaluator and compared and evaluated with the tool data in the data memory of the control or evaluator. This has the advantage that an inspection can be performed to see if the tool is equipped. A simpler method can detect whether the tool is within or outside the wear limit.

After performing the upper and / or lower tool measurements, they are moved to each other in the working position by moving the upper and / or lower tools along the upper and / or lower positioning device for the next machining step. Is more preferably intended. No additional equipment time or transfer of upper and / or lower tool holders to the warehouse for tool holders may be made.

The present invention and further advantageous embodiments and developments thereof will be described and described in detail with reference to the examples shown in the figures below. The features obtained from the description and drawings can be applied individually or in any combination in accordance with the present invention.

FIG. 4 is a schematic table of further overlapping stroke movements of the tappet of FIG. 1 in the Y and Z directions. FIG. 5 is a schematic view of the tool machine having the geographic feature of FIG. 1 as viewed from above. FIG. 6 is a schematic side view of the upper and lower drive devices at the working position of the upper tool with respect to the lower tool. FIG. 7 is a schematic side view of the upper and lower drive devices at the measurement position for the upper tool. FIG. 8 is a schematic view of the tool body of the upper tool in the measuring method by the measuring device in the lower drive device.

The tool machine 1 is used for machining a plate-like workpiece 10 that may be placed within the frame interior 7 for machining purposes, which is not shown in FIG. 1 for simplification. The work piece 10 to be machined is placed on a work piece support 8 provided in the frame interior 7. The lower tool 9 is supported by the lower horizontal frame leg 4 of the machine frame 2 in the recess of the workpiece support 8, for example, in the form of a punching mold. The punching mold may be provided with a mold opening. At the time of punching, the upper tool 11 formed as a punching stamp sinks into the mold opening of the lower tool formed as a punching mold.

The upper tool 11 and the lower tool 9 can be used for the deformation of the workpiece 10 as a bending stamp and a bending mold instead of the punching stamp and the punching mold.

The upper tool 11 is fixed in the tool holder at the lower end of the tappet 12. The tappet 12 is a portion of the stroke drive device 13 that can be used by the upper tool 11 to move the upper tool 11 along the stroke axis 14 in the stroke direction. The stroke axis 14 extends in the direction of the Z axis of the coordinate system of the numerical control 15 of the tool machine 1 implied in FIG. The stroke drive device 13 may be moved across the positioning shaft 16 in the direction of the double arrow perpendicular to the stroke shaft 14. The positioning axis 16 extends in the direction of the Y axis of the coordinate system of the numerical control 15. The stroke drive device 13 that receives the upper tool 11 moves across the positioning shaft 16 using the motor drive device 17.

The movement of the tappet 12 along the stroke axis 14 and the positioning of the stroke drive device 13 along the positioning axis 16 extend in the form of the drive device 17, especially in the direction of the positioning axis 16, and are fixedly coupled to the machine frame 2. This is done using a motor drive 17 in the form of a spindle drive 17 with a spindle 18. The stroke drive device 13 is guided over the positioning shaft 16 on the three guide rails 19 of the upper frame legs 3 during exercise. Among them, the guide rail 19 can be identified in FIG. The remaining guide rail 19 extends in parallel with the illustrated guide rail 19 from which an interval is provided in the direction of the X-axis of the coordinate system of the numerical control device 15. The guide shoe 20 of the stroke drive device 13 moves on the guide rail 19. The mutual engagement of the guide rail 19 and the guide shoe 20 is formed so that this coupling between the guide rail 19 and the guide shoe 20 can also receive a load acting in the vertical direction. Correspondingly, the stroke drive device 13 is suspended by the machine frame 2 over the guide shoe 20 and the guide rail 19. Another component of the stroke drive 13 is the wedge gear 21, which allows the position of the upper tool 11 to be adjustable with respect to the lower tool 9.

The lower tool 9 is movably received along the lower positioning shaft 25. The lower positioning axis 25 extends in the direction of the Y axis of the coordinate system of the numerical control 15. Preferably the lower positioning shaft 25 is oriented parallel to the upper positioning shaft 16. The lower tool 9 may move directly along the positioning shaft 25 by the motor control device 26 at the lower positioning shaft 16. Alternatively or complementarily, the lower tool 9 is also provided in the stroke drive device 27, which is movable along the lower positioning shaft 25 using the motor control device 26. The control device 26 is preferably formed as a spindle drive device. The lower stroke drive device 27 may correspond to the structure of the upper stroke drive device 13. Similarly, the motor control device 26 may correspond to the motor control device 17.

The lower stroke drive device 27 is slidably supported by a guide rail 19 assigned to the lower horizontal frame leg 4. Since the guide shoe 20 of the stroke drive device 27 moves on the guide rail 19, the connection between the guide rail 19 and the guide shoe 20 can also receive a load acting horizontally by the lower tool 9. Correspondingly, the stroke drive device 27 is also suspended across the guide shoe 20 and the guide rail 19 by the mechanical frame 2 and at intervals with respect to the guide rail 19 and the guide shoe 20 of the upper stroke drive device 13. The stroke drive 27 can also include a wedge gear 21 that can adjust the position or height of the lower tool 9 along the Z axis.

Numerical control 15 allows both the motor drive 17 for movement along the upper positioning shaft 16 of the upper tool 11 and the single or multiple motor drives 26 for movement along the lower positioning shaft 25 of the lower tool 9 to each other. Can be controlled independently of. Thereby, the upper and lower tools 11 and 9 can be synchronously moved in the direction of the Y axis of the coordinate system. Similarly, the independent movements of the upper and lower tools 11 and 9 can be controlled in different directions. These independent movements of the upper and lower tools 11 and 9 can be controlled simultaneously. Improved machining flexibility of the workpiece 10 is achieved by releasing the interlocking movement between the upper tool 11 and the lower tool 9. The upper and lower tools 11 and 9 for machining the workpiece 10 can be formed in various ways.

The component of the stroke drive device 13 is the wedge gear 21 shown in FIG. The wedge gear 21 includes two input side wedge gear members 122 and 123, and two output side wedge gear members 124 and 125. The latter is constructively grouped into a structural unit in the form of a double wedge 126 on the output side. The tappet 12 is rotatably supported around the stroke shaft 14 on the double wedge 126 on the output side. The motor rotation drive device 128 is housed in the double wedge 126 on the output side and moves the tappet 12 along the stroke shaft 14 as needed. At that time, the tappet 12 can be rotated to the left or to the right by the double wedge shown in FIG. The tappet bearing 129 is schematically shown. On the one hand, the tappet bearing 129 allows a low friction rotational motion around the stroke shaft 14 of the tappet 12, while the tappet bearing 129 axially supports the tappet 12 and the stroke shaft 14 on the tappet 12 accordingly. The load acting in the direction of is carried out into the double wedge 126 on the output side.

The output-side double wedge 126 is defined by a wedge surface 130 and a wedge surface 131 of the output-side drive member 125. The wedge surfaces 130 and 131 of the wedge gear drive members 124 and 125 on the output side face the wedge surfaces 132 and 133 of the wedge drive members 122 and 123 on the input side. The vertical guides 134 and 135 move the input side wedge drive member 122 and the output side wedge drive member 124, and the input side wedge drive member 123 and the output side wedge drive member 125 in the Y-axis direction, that is, the stroke drive device 13. Are guided relatively movably with respect to each other in the direction of the positioning shaft 16.

The wedge drive member 122 on the input side has a motor drive unit 138, and the wedge drive member 123 on the input side has a motor drive unit 139. Both drive units 138 and 139 jointly form the spindle drive device 17.

Common to the motor drive units 138 and 139 are the drive spindle 18 shown in FIG. 1 and the stroke drive devices 13 and 27 axially supported by the mechanical frame 2 and as a result, on the support structure side.

With respect to the motor drive units 138 and 139, the input side wedge drive members 122 and 123 move, for example, toward each other along the positioning shaft 16, thereby, on the one hand, between the input side wedge drive members 122 and 123. On the other hand, it is operated so that a relative motion occurs between the wedge drive members 124 and 125 on the output side. As a result of this relative motion, the double wedge 126 on the output side and the tappet 12 supported by the double wedge 126 move downward along the stroke axis 14. A punched stamp attached to the tappet 12, for example as an upper tool 11, performs a work stroke, at which time the workpiece 10 placed on the workpieces 28, 29 or the workpiece support 8 is machined. The opposition to each other of the wedge drive members 122, 123 causes the tappet 12 to be lifted or moved upward again along the stroke axis 14.

The stroke drive device 13 of FIG. 2 described above is preferably formed in the same manner as the lower stroke drive device 27 and receives the lower tool 9.

FIG. 3 shows a schematic table of possible stroke movements of the tappet 12. The table shows the course of strokes along the Y and Z axes. Overlapping control of the movement of the tappet 12 along the stroke axis 14 and the positioning axis 16 may be controlled, for example, a stroke motion extending diagonally below the tappet 12 to the workpiece 10 as shown by the first straight line A. .. Subsequently after performing the stroke, the tappet 12 can be lifted vertically, for example, as indicated by the straight line B. In order to position the tappet 12 in a new working position on the workpiece 10, only movement along the Y axis of a straight line C, for example, is subsequently performed. This can be followed, for example, by repeating the work sequence described above. As long as the workpiece 10 is moved on the workpiece bases 28, 29 for the subsequent machining step, the movement along the straight line C may also be omitted.

The possible stroke movement of the tappet 12 with the upper tool 11 shown in the table of FIG. 3 is preferably combined with the stationary lower tool 9. The lower tool 9 is then positioned within the machine frame 2 so that the upper and lower tools 11 and 9 occupy defined positions at the end of the working stroke of the upper tool 11.

This exemplary overlapping stroke process can be controlled for both the upper tool 11 and the lower tool 9. Overlapping stroke movements of the upper and / or lower tools 11 and 9 may be controlled depending on the machining of the workpiece 10 to be performed.

In FIG. 4, a schematic table showing the stroke motion of the tappet 12 is shown by the line D schematically shown along the Y-axis and the Z-axis. Deviating from FIG. 3, in this embodiment, the stroke movement of the tappet 12 can follow a curved or arcuate transition by appropriately controlling the overlap of movements in the Y and Z directions by the control 15. Is intended. Such flexible duplication of movement in the X and Z directions solves the problems inherent in machining. Control of such curvilinear transitions may be contemplated for the upper tool 11 and / or the lower tool 9.

FIG. 5 shows a schematic view of the tool machine 1 of FIG. One work table 28 and 29 extend to the side of the machine frame 2 of the tool machine 1, respectively. The work table 28 may be assigned, for example, to a loading station on which the raw work 10 is placed on the work table 28, which is not shown in detail. A feeding device 22 including a plurality of grips 23 is provided to grip the workpiece 10 defined on the workpieces 28 and 29 and mounted on the workpiece 28. The workpiece 10 is guided in the X direction through the machine frame 2 by using the feeding device 22. Preferably, the feeder 22 can be movably controlled in the Y direction as well. Thereby, free movement of the work 10 on the XY planes can be attempted. The workpiece 10 can move in the X direction and in the direction opposite to the X direction by the feeding device 22 according to the work task. This movement of the workpiece 10 can be adapted to the movement of the upper tool 11 and the lower tool 9 in the Y direction and vice versa for the respective machining tasks.

Another workpiece 29 is provided on the machine frame 2 facing the workpiece 28. This can be assigned, for example, to an unloading station. Alternatively, loading and unloading of the processed workpiece 10 having the raw workpiece 10 and the workpiece 81 may also be assigned to the same workpieces 28, 29.

The tool machine 1 can further include a laser processing device 201, particularly the laser cutting machine shown in the top view of FIG. 5 only schematically. This laser processing device 201 can be formed as, for example, a CO ₂ laser cutting machine. The laser machining apparatus 201 includes a laser source 202 that produces a laser beam 203 that is guided and focused in a laser machining head, particularly a laser cutting head 206, using a generally shown light beam guide 204. The laser beam 204 is then oriented perpendicular to the surface of the workpiece 10 by a cutting nozzle to machine the workpiece 10. The laser beam 203 acts on the workpiece 10 at the machining site, especially at the cutting site, preferably with the process gas flow. The cutting position where the laser beam 203 is generated on the workpiece 10 is adjacent to the machining position of the upper tool 11 and the lower tool 9.

The laser cutting head 206 is movable at least in the Y direction, preferably in the Y and Z directions, by a linear drive 207 having a linear axis system. This linear axis system that receives the laser cutting head 206 may be assigned to the machine frame 2 and fixed or integrated therein. A light path opening may be provided in the workpiece 28 under the working space of the laser cutting head 206. Preferably, a ray capture device for the laser beam 21 may be provided beneath the ray path opening. The ray passage opening and optionally the ray capture device can also be formed as a structural unit.

Alternatively, the laser processing apparatus 201 can also include a solid-state laser whose light beam is guided to the laser cutting head 206 with the help of optical wiring as the laser source 202.

The work bases 28, 29 may extend directly to the work support 8, which is at least partially surrounded by the lower tool 9. In the space created between them, the lower tool 9 can move in the Y direction and vice versa along the lower positioning shaft 25.

For example, the machined work piece 10 is placed on the work table 28, and the work part 81 is cut out from the cut 83 except for the residual connection 82 by, for example, punching or laser beam processing. This residual connection keeps the workpiece 81 in the workpiece 10 or the rest of the residual grid. To separate the geographic part 81 from the geographic 10 the geographic part 10 is positioned on the upper and lower tools 11 and 9 for punching and ejection steps using the feeder 22. At that time, the residual connection 82 is separated by the punching stroke of the upper tool 11 to the lower tool 9. The work part 81 can be ejected downward, for example, by a partial tilt of the work support 8. Alternatively, in the case of a relatively large work part 81, the cut out work part 81 is returned to the work table 28 or the work table 29 again to carry out the work part 81 and the residual grid. The small workpiece part 81 may also optionally be ejected through an opening in the lower tool 9.

FIG. 6 shows the upper drive device 17 in a schematic simplification with respect to the device shown in FIG. The lower drive device 26 is provided facing the upper drive device 17. In the embodiment, the upper stroke shaft 14 of the upper drive device 17 is in the stroke shaft 30 of the lower drive device 26. The upper stroke shaft 14 and the upper position shaft 35 of the upper tool 11 completely overlap. Similarly, the lower stroke shaft 14 and the lower position shaft 48 of the lower tool 9 completely overlap. The positions of the upper and lower drive devices 17 and 26 shown in FIG. 6 may indicate the machining positions of the upper tool 11 and the lower tool 9.

The upper drive device 17 includes an upper measuring device 601. The upper measuring device 601 is provided on, for example, a double wedge 126. The upper measuring device 601 is arranged close to the tappet 12 that receives the upper tool. The measuring device 601 is oriented to the lower driving device 26 by the measuring shaft 602. Preferably, the measuring axis 602 of the measuring device 601 can be oriented parallel to the position axis 35. The orientation of the measuring axis 602 is also related to the selection of the measuring device 601.

The lower driving device 26 is provided with a lower measuring device 604 in which the measuring shaft 605 is directed in the direction of the upper driving device 17. The measurement axis 605 can preferably be oriented parallel to the position axis 48. The lower measuring device 604 is preferably located on the bracket carriage 606, which is part of the motor drive device 26. The bracket carriage 606 is preferably guided movably along a lower position axis 25, which is particularly a spindle.

In the embodiment of FIG. 6, only one measuring device 601 is provided in the driving device 17, and the measuring device 604 is provided in the driving device 26. Alternatively, a plurality of measuring devices may be provided in one or both of the two drives 17, 26.

According to the first embodiment of the measuring devices 601 and 604, a non-contact sensor, particularly a distance sensor, is provided. With such a distance sensor, the front surface of the tool body 39 of the upper tool 11 (FIG. 8) facing each other or the counter tool body of the lower tool 9 can be detected. Advantageously, the measuring devices 601 and 604 are formed as a line laser. Alternatively, a camera system such as a CCD camera or other imaging device may be introduced in which corresponding data can be detected from the facing upper tool 11 or lower tool 9 and processed by the evaluator and supplied to the control 15.

FIG. 7 shows the positioning of the upper tool 11 in the lower drive device 26 above the measuring device 604. Here the upper drive 17 may be moved along the upper positioning shaft 16 and / or the lower drive 26 may be moved along the lower positioning shaft 25. The distance between the position axis 48 and the measurement axis 605 of the lower measuring device 604 is, for example, the distance A. Due to the positioning of the upper drive 17 it is also moved to the lower drive 26 by a distance A with respect to the stroke axis 14 or the position axis 35 of the upper tool 11 so that measurements can be performed. At such a position, for example, the distance between the measuring device 604 and the lower surface of the cutting edge 38 and / or the stamp surface 43 or the tool body 39 of the upper tool 11 can be calculated. Thereby, on the other hand, it is detected whether or not the upper tool 11 is received by the upper drive device 17. Therefore, the height of the tool body 39 in the upper tool 11 and, in some cases, wear can be detected. The data is transferred to control 15 for further machining. The same is true for the lower tool as long as the upper measuring device 601 is directed at the lower tool 9 by its measuring shaft 602.

The above-mentioned parameters for the tool body 39 of the upper tool 11 can also be detected when the movement of the upper tool 11 across the lower measuring device 604 is controlled.

In the orientation of the upper drive 17 to the lower drive 26 shown in FIG. 7, further detection of the shape of the stamped surface 43 of the machining tool 37 can be detected and / or wear can be confirmed. For example, the position of the upper drive device 17 with respect to the lower drive device 26 in the interval A is performed. Subsequently, the upper tool 11 and the stroke shaft 14 are driven by rotation. The shape of the stamp surface 43 can be detected by scanning the stamp surface 43 of the tool body 39 through, for example, the measurement point 607 of the distance sensor 604. For example, each inversion can increase the spacing R of the measurement _points 607 in the Y axis (tool axis) shown in FIG. In this way, for example, the tool type can be determined. Alternatively, a spiral scan operation on the underside of the tool body 39 of the upper tool 11 can also be performed by a linear increase of the spacing R of the measurement _points 607 to the Y1 axis shown in FIG. As a result, the shape of the connecting edge 38 of the tool body 39 of the upper tool 11 determined on the stamp surface 43 and the wear that may occur can be detected. This is done, for example, by detecting polar coordinates. The same procedure can be done by measuring device 601 for the lower tool 9.

Damage to the connecting edge 38 of the tool 39 or the counter-cutting edge of the counter-tool is also detected by the measuring devices 601 and 604, especially after machining the workpiece 10 and before the tool is replaced.

Since the data detected by the measuring devices 601 and 604 are transferred to the control 15, these are considered for the next machining of the workpiece 10 by the tool measured as correction data. This involves inspection or detection of the tool body of the upper tool and the counter tool body of the lower tool prior to the start of the feature machining, which is followed immediately by the machining of the feature 10 without further equipment steps. There is an advantage to get.
