Abstract
Description
Technical Field
[0001] The present invention relates to an equipping device for equipping a tool for punching or forming plate-shaped material and a method for the equipping. Background Art
[0002] Tools used for forming or stamping consist of a punch and a die, preferably with a stripper arranged between them. These stamping and forming tools are used in machine tools for processing sheet materials, particularly sheet metal. Due to processing, these tools experience wear, meaning that at least one cutting edge of the punch and / or die no longer has the required sharpness. This can lead to inaccuracies or reduced quality during processing. Consequently, these tools need to be reground. This also has the advantage of extending the tool's service life.
[0003] After tool regrinding, the length of the punch and / or the height of the die change. Therefore, it is necessary to detect these tools with respect to their actual dimensions so that the machine tool can take these actual dimensions into account during the punching, forming and cutting processes being operated, at least with respect to the material thickness of the sheet material to be processed.
[0004] A tooling device is known in which a punch of a tool is inserted into a punch receptacle to measure the punch length. Subsequently, after removing the punch, a die is inserted into the tooling device to measure the die height. The punch is then reinserted to measure the depth of penetration of the punch into the die. These measured individual values are then associated with one another and transmitted to the machine tool. Summary of the Invention
[0005] The object of the present invention is to provide a setup device and a method for equipping a tool for punching and forming sheet metal materials, by means of which the setup time for the setup process can be reduced.
[0006] This object is achieved by a tooling apparatus for punching or forming sheet-like material, the tool comprising at least one punch or one die, wherein the punch is insertable into a punch receptacle and the die is insertable into a die receptacle, and the punch receptacle is movable at least along a guide toward the die receptacle, wherein the punch receptacle is movable along the guide into a measuring position, wherein the punch rests on a measuring surface of a measurement object and the measurement object rests with its underside on the die, wherein in this measuring position the distance between the punch receptacle and the zero point of the die receptacle and the distance between the measurement object and the zero point of the die receptacle can be measured, and an evaluation device outputs the punch length of the punch and the die height of the die or the die height of the die with a die carrier. The advantage of the tooling apparatus is that both the punch length and the die height of the die with or without a die carrier can be measured in a single working step or testing step. This reduces the time required for tooling.
[0007] Furthermore, the measurement object is preferably designed as a measuring plate, which preferably has a defined thickness. This simplifies the detection of the punch length and die height, since, starting from the zero point of the die height, both the die support area and the punch length can be detected in a simple manner. When determining the punch length, this is particularly due to the fact that the punch body or the punch calibration ring is positioned in a defined position in the punch receptacle, making it possible to detect a defined dimension for detecting the distance of the punch receptacle from the zero point of the die.
[0008] Furthermore, the measuring object is preferably transferred from the non-use position to a measuring position between the punch in the punch receiving portion and the die in the die receiving portion. This can be done manually. A drive can also be provided by which this displacement movement is controlled. Thus, a measuring object or a gauge block (Endmaβ) that is not connected to the equipment device can be transferred to the measuring position by a simple displacement movement, in particular a pivoting movement, so that the punch length and the die height can be detected subsequently by displacing the punch receiving portion onto the die receiving portion.
[0009] Preferably, after the punch length and die height have been measured, the measuring object can be moved to a non-use position, the punch receiving portion can be moved along the guide device toward the die, and the penetration of the punch into the die opening can be checked by the measuring device. This allows a penetration check to ensure the correct orientation of the punch relative to the die or die opening. Simultaneously, the presence of a die gap can be detected.
[0010] Another advantageous configuration of the equipment provides for the measurement object to be movable along a guide or a separate column. For example, the measurement object can be positioned at a distance from the die receptacle and the punch receptacle, allowing collision-free pivoting between the punch and the die. Subsequently, when the punch receptacle is lowered onto the die, the measurement position for determining the punch length and die height can be automatically assumed.
[0011] The tooling device preferably includes a stripper receptacle, which is arranged between the die receptacle and the punch receptacle and is preferably also movable along the guide. Many tools for stamping or forming include such strippers or hold-down devices. To check the necessary immersion depth of the punch into the die, a stripper should be included, provided that it is used in the tool.
[0012] In order to detect the immersion depth of the punch into the die, the punch receiver can preferably be transferred along a guide device to a measuring position for abutting against the measurement object, in which measuring position the stripper arranged in the stripper receiver abuts against the body of the punch or the calibration ring, and the measuring device detects the distance between the zero point of the die and the stripper receiver. The immersion depth of the punch can be detected by the difference between the distance between the stripper receiver and the zero point of the die receiver and the detected punch length. The immersion depth is the free length of the punch with which the punch can be immersed in the die opening, both in the presence and absence of the stripper. The immersion depth of the punch needs to be taken into account in the stamping tool, because the immersion depth required for processing plate-like materials should at least include the thickness of the plate-like material and the immersion of the punch into the die opening.
[0013] Furthermore, it is preferably provided that the measuring device generates a tool-specific data set for the machine tool from the acquired data. This data set is transmitted to the machine tool so that the actual dimensions of the machining tool are taken into account for the subsequent machining of the sheet material. The data set can also be transmitted to a database or cloud, making it accessible to the machine tool and / or the controller.
[0014] Advantageously, the punch receptacle can be moved into the measuring position against the resetting element and can preferably be returned autonomously to the initial position by the resetting element. This enables simple operation.
[0015] Advantageously, when an ejector element is present, a reset element is also provided, against which the ejector receptacle can be moved into the measuring position and, preferably, can be returned to the initial position autonomously by means of the reset element. Alternatively, at least the initial position and the measuring position of the punch receptacle and / or the ejector can be controlled by a drive.
[0016] The equipping device preferably has a base frame in which the die receptacle is arranged and on which at least one guide device for the punch receptacle and preferably for the stripper receptacle is arranged.
[0017] The punch receptacle and / or the stripper receptacle and / or the die receptacle preferably each have an insertion opening pointing toward the front face of the base frame, each of which has at least one releasable connecting element for securing the punch and / or the stripper and / or the die in the respective receptacle. This allows the punch and / or the stripper and / or the die to be positioned manually in the respective receptacle in a simple manner. The process-assisted insertion of the punch and / or the stripper and / or the die can also be accomplished using auxiliary tools.
[0018] The punch receiving portion and, if necessary, the ejector element can preferably be moved relative to the die receiving portion into a replacement position and locked in this replacement position preferably by a lever assembly or by an actuable locking device. The actuable locking device can be electrically, pneumatically, hydraulically, or magnetically actuated. This allows the tool to be subsequently easily removed from the equipment, for example, via the cassette, which also holds the tool in the tool magazine in the machine tool.
[0019] A drawer is preferably provided on the base frame of the tooling device for receiving a cassette for the tool, which cassette receives the punch, preferably the ejector, and the die or the die with the die carrier. After the measurement, when the entire tool is to be removed from the tooling device, the cassette can be inserted into the drawer so that the tool can then be removed by closing and reopening the drawer.
[0020] The housing for receiving the tool preferably has a clamping element for the punch and preferably for the stripper and the die, wherein after clamping the punch and preferably for the stripper and the die, the clamping force of the clamping element is greater than the holding force of the releasable connecting element in the insertion opening of the punch receptacle, preferably for the stripper receptacle and the die receptacle. This makes it possible to easily release the tool when withdrawing the housing from the receptacle.
[0021] Preferably, a calibration standard is provided for equipping the device, by means of which a defined distance from the zero point of the die receiving portion to the punch receiving portion, and preferably from the zero point of the die receiving portion to the stripper receiving portion, can be set. This calibration standard can be inserted into the die receiving portion. The punch receiving portion and preferably the stripper receiving portion can then be set on the calibration standard, so that the measuring device can then be calibrated with respect to the corresponding distances.
[0022] The mounting device preferably has a cassette receptacle on the base frame, which cassette receptacle has an unlocking element. This allows the cassette, which receives the punch, preferably the stripper element, and the die, to be positioned in the cassette receptacle. Subsequently, the cassette can be opened, in particular the clamping element can be opened or unlocked, using the unlocking element, so that the punch, preferably the stripper, and the die can be easily removed from the cassette in order to be inserted into the punch receptacle, preferably the stripper receptacle, and the die receptacle.
[0023] The object underlying the present invention is also achieved by a method for equipping a tool for punching or forming sheet-like material using an equipping device, the tool comprising at least one punch receptacle and one die receptacle, and at least one guide device, by which the punch receptacle can be moved toward the die receptacle, wherein the punch is inserted into the punch receptacle and the die is inserted into the die receptacle, and the punch receptacle is moved along the guide device toward the die receptacle to transfer the punch receptacle into a measuring position, in which the punch rests on a measuring surface of a measurement object, the measurement object being positioned with its underside against the die, and the distance between the punch receptacle and the zero point of the die receptacle, as well as the distance between the measurement object and the zero point of the die receptacle, is measured by a measuring device. An evaluation device then outputs the punch length and die height. The die height can include both a die without a die carrier and a die with a die carrier and preferably a spacer element arranged therebetween. By moving or advancing the punch receptacle toward the die at the measurement point, the punch length and die height can be measured simultaneously. This reduces equipping time.
[0024] An advantageous embodiment of the method provides that, before the punch receptacle is moved into the measuring position, the measurement object is moved from the non-use position into the measuring position between the punch in the punch receptacle and the die in the die receptacle. This allows for an improved readiness of the equipment for measuring punch length and die height.
[0025] After the punch length and die height have been measured, the measuring object is moved into the non-use position and the punch receiver is moved along the guide device toward the die so that the penetration of the punch into the die opening is detected by the measuring device. This allows a penetration check to ensure that the die and punch are also aligned or oriented relative to each other and together form a tool.
[0026] An advantageous configuration of the method provides that the equipment includes a stripper receptacle, into which the stripper is inserted, and a punch receptacle with an inserted punch is moved along a guide device to a measuring position, wherein, during the displacement movement, the stripper rests on the body of the punch or the calibration element, and the stripper receptacle is moved along the guide device via the punch receptacle. The measuring device can then detect the distance between the zero point of the die and the stripper receptacle and the distance between the zero point of the die and the punch receptacle. The thickness of the measurement object supported on the die is stored in the measuring device. Subsequently, not only the punch length, the die height and the immersion depth of the punch into the die (in the case of a tool with a stripper) can be detected.
[0027] Furthermore, the measurement values of the tools in the equipment, acquired by the measuring device, preferably form a tool-specific data set that is transferred to a database, the cloud, or the machine tool. This can be done wirelessly or wired. The machine tool can thus control the work steps using the precisely acquired geometric data of the tool.
[0028] Furthermore, preferably, after measuring the tool, the punch receptacle and preferably the stripper receptacle are moved relative to the die receptacle into a replacement position and locked. The die receptacle is preferably fixedly arranged in the equipment device, in particular in a base frame of the equipment device. This replacement position can be occupied, for example, by a locking device. For example, a pivoting lever of the lever assembly can lock the punch receptacle and preferably the stripper receptacle, which are moved along the guide device, in the replacement position.
[0029] Preferably, a drawer for receiving the cassette is provided in the base frame, which drawer is opened for removing the tool in order to insert the cassette so that the cassette can then be applied to the tool by closing the drawer. This has the advantage that after the drawer has been opened, the cassette, which holds and receives the tool, can be removed as a unit together with the tool and can be directly inserted into the tool magazine of the machine tool.

[0051] The die receiving portion 21 is provided on or in the base frame 14, in particular, on or in the base plate 15. The die receiving portion 21 is fixedly arranged on the base frame 14. A punch receiving portion 22 is provided above the die receiving portion 21. The punch receiving portion 22 is received on the guide device 17 and is movable along the guide column 19. Preferably, an ejector receiving portion 23 is provided between the punch receiving portion 22 and the die receiving portion 21. The ejector receiving portion 23 is guided on the guide device 17 and is movable up and down along the guide column 19.
[0052] The punch receptacle 22 and the stripper receptacle 23 are arranged in an initial position 24 or basic position. A restoring element 26 acts on the punch receptacle 22 and holds the punch receptacle 22 in the initial position 24 by means of the restoring element.
[0053] Preferably, a restoring element 26 is also provided on the ejector element 23 in order to position it in the initial position 24. The punch receiving part 22 and the ejector element 23 are movable and displaceable towards the die receiving part 21 against the restoring force of the restoring element 26.
[0054] The punch receiving portion 22 includes an insertion opening 29 for receiving a punch 36 of a tool 35. Figure 4 and Figure 5 Preferably, a detachable connecting element 31 is provided associated with the insertion opening 29 so that after the punch 35 (in particular its retaining pin 41 ) has been inserted, the punch 36 is securely received.
[0055] The stripper receiving portion 23 includes an insertion opening 29, Figure 4 and Figure 5The stripper 37 of the tool 35 can be inserted into the insertion opening. The insertion opening 29 of the stripper receptacle 23 also has a detachable connecting element 31 in order to secure the stripper 37 after insertion into the stripper receptacle 23.
[0056] The die receiving portion 21 also comprises an insertion opening 29 for inserting a punch according to Figure 4 and Figure 5 The die 38 of the tool 35 is held firmly in the die receiving portion 21 by means of at least one releasable connecting element 31. Figure 4 and 5 Both the die 38 shown in the figure with the die carrier 39 and the die 38 without the die carrier can be inserted into the die receiving portion 21. Between the die carrier 39 and the die 38 a spacer element 40 can be arranged.
[0057] The punch receiving portion 22 and the ejector receiving portion 23 preferably act on and are movable along two guide columns 19. A sensor rod 43 of the measuring device 42 is arranged parallel to the guide columns 19, along which a sensor 44 of the punch receiving portion 22 and a sensor 45 of the ejector receiving portion 23 are movably guided.
[0058] Another column 47 is provided parallel to the guide device 17, on which a measurement object 48 is fixed. The measurement object 48 can be moved up and down along the guide column 47 or kept at a predetermined height. The measurement object 48 has, for example, a pivotable measurement plate 49 that can be pivoted horizontally (preferably parallel to the base plate 15). The measurement object 48 can also be moved from the base plate 15 according to the Figure 1 The non-use position 51 is pivoted into the measuring position 78, which will be referred to below. Figure 7 Discuss in more detail.
[0059] The displacement movement of the punch receiving portion 22 and / or the stripper receiving portion 23 toward the die receiving portion 21 can be manually controlled. A motor drive can also be provided, by which the feed movement is generated.
[0060] The equipment 11 includes an evaluation device 27 for analyzing the measurement data detected by the measuring device 42. The evaluation device is connected to the machine tool 28 wirelessly or by wire to transmit the data of the detected tool 35 to the machine tool or to the cloud or database. The data set can be retrieved or downloaded from the cloud or database at a later time.
[0061] exist Figure 4 A perspective view of a cassette 34 receiving a tool 35 is shown in FIG. Figure 5 Show the basis Figure 4Schematic cross-sectional view of a cassette 34 with a tool 35. This cassette 34 can be positioned interchangeably in the tool magazine of a machine tool 28, for example, by means of a cassette guide 56. The machine tool 28 can be a punching and / or bending machine or a laser cutting punching and / or bending machine. The cassette 34 receives the punch 36 via a clamping element 57. The clamping element 57 preferably acts on the body 58 of the punch 36 or on the calibration ring of the punch 36. The ejector 37 is received in the cassette 34 at a distance from the punch 36. The ejector is also held by the clamping element 57. The die 38 is held in the cassette 34 at a distance from the ejector 37 by the clamping element 57. In this embodiment, the die 38 is arranged in a die carrier 39. A spacer disk 40 is arranged between the die carrier 39 and the die 38.
[0062] The equipment 11 is used to measure the geometric data of the tool 35. One measurement value is the punch length 61 ( Figure 5 ), the punch length is defined, for example, by the upper edge of the main body 58 of the punch 36 to the end face 62 of the punch 36 or the processing tool 63.
[0063] Another measurement is the die height 65 ( Figure 5 The die height 65 is determined from the underside of the die 38 or the die carrier 39 to the support surface 66 of the die 38 surrounding the opening 67. Since the support surface 66 of the die 38 is subject to wear, a spacer disk 40 can be provided to adjust the defined die height 65 between the die 38 and the die carrier 39.
[0064] Another measured value is the immersion depth. This immersion depth is the distance between the underside of the stripper 37 and the end face 62 of the processing tool 63 of the punch 36 protruding relative to the underside and is referred to Figure 11 Provide a description.
[0065] exist Figure 6 shows a schematic cross-sectional view of a box 34 with a tool 35 serving as a forming tool. This forming tool can be used, for example, to introduce a bowl-shaped recess into sheet-like material. This forming tool is merely an example. In this forming tool, one measured value is the punch length 61, which is defined, for example, from the upper edge of the body 58 of the punch 36 to the end face 62 of the punch 36.
[0066] Another measurement is based on Figure 6 The die height 65 is determined from the underside of the die 38 or the die carrier 39 to the supporting surface 66 of the die.
[0067] The detection of these measurements of tool 35 is described as follows:
[0068] The cassette receiving portion 71 is provided on the housing 12 of the equipment device 11. The cassette receiving portion 71 is provided with an unlocking element 72. The cassette 34 equipped with the tool 35 is inserted into the cassette receiving portion 71. By operating the unlocking element 72, the clamping force of the clamping element 57 of the cassette 34 can be released. Subsequently, the punch 36 and the stripper 37 are removed from the cassette 34. The punch 36 is inserted into the punch receiving portion 22, while the stripper 37 is inserted into the stripper receiving portion 61. In order to insert the die 38 into the die receiving portion 21, the drawer 74 on the housing 12 can preferably be opened ( Figure 7 ). Subsequently, the die 38 can be easily inserted preferably with the box body 34. The punch 36, the ejector 37 and the die 38 can also be taken out of the box body manually.
[0069] Figure 8 The equipment device 11 is shown in an initial position 24 for detecting measured values. The punch 36, the ejector 37 and the die 38 are inserted into the corresponding receiving parts 21, 22, 23. The measuring object 48, in particular the measuring plate 49, is pivoted into the measuring position 52. This initial position 24 for detecting measured values is in accordance with Figure 8 . This cross-sectional view shows that the punch 36 inserted in the punch receptacle 22 is spaced apart from the ejector 37 in the ejector receptacle 23. A distance is again provided between the ejector 37 and the object to be measured 48. The object to be measured 48 is arranged elevated or spaced apart from the die 38 in the die receptacle 21.
[0070] Starting from this initial position 24 of the equipment 11, the following Figures 10 to 12 , the individual steps leading to the assumption of the measuring position 52 for determining the punch length 61 , the die height 65 and the immersion depth 69 are shown.
[0071] The punch receptacle 22 is lowered until the body 58 of the punch 36 bears against the ejector 37 .
[0072] Subsequently, the punch receiving portion 22 is moved further downwards together with the ejector element 23 until the end face 62 of the punch 36 bears against the measuring plate 49. Figure 11 Shown in.
[0073] A further displacement movement then takes place, in which the punch receptacle 22, the stripper receptacle 23 and the measured object 48 are moved together relative to one another at a correspondingly defined distance until the measured object 48 rests on the support surface 66 of the punch 38. Figure 12 This position is the measurement position 52 .
[0074] The die 38 is supported in the die receptacle 21. This contact surface forms the zero point 81 for the measuring device 42. The object 48 to be measured is supported on the die 38. A distance A1 is detected by the sensor 46, which is arranged on the object 48, via the sensor rod 43. The distance between the measuring plate 48 or the underside of the object 48 to the sensor 46 is known and defined. Therefore, the die height 65 can be determined from this measured distance A1.
[0075] Furthermore, the distance A2 between the zero point 81 and the sensor 44 of the punch receptacle 22 is detected. Since the sensor 44 is at a defined distance from the underside of the punch receptacle 22 or the insertion opening 29, the punch length 61 of the punch 36 can be determined by the difference between the distances A2 and A1.
[0076] In addition, the distance to the zero point 81 is detected by the sensor 45 of the ejector receptacle 23. The difference between the distances A3 and A1 yields the immersion depth of the processing tool 63 of the punch 36.
[0077] exist Figure 13 Shown in the Figure 9 An alternative to the initial position of the measuring object 48. In this alternative embodiment, the measuring plate 49 is already supported on the support surface 66 of the punch 38. However, the displacement movement of the punch receiving part 22 and the stripper receiving part 23 is as follows Figures 9 to 11 Proceed in the same manner as described in .
[0078] exist Figure 14 Another arrangement of the punch receiving portion 22 and the stripper receiving portion 23 relative to the die 38 is shown in FIG. Figure 12 Starting from the measuring position 52, the measuring object 48 can be pivoted into the non-use position 51. Subsequently, the punch receiving part 22 and the stripper receiving part 23 are moved further toward the die 38. The processing tool 63 of the punch 36 is sunk into the opening 67 of the die 38. This sunken position 82 can also be detected by the sensors 44 and 45. This sunken position check means that the punch 36 and the die 38 are properly associated and, as long as the processing tool 63 is sunk into the opening 67 of the die 38, a collision during use of the machine tool is prevented.
[0079] exist Figure 15 The equipment device 11 is shown in the replacement position 84. Figure 14 Starting from the position of the punch receiving portion 22 and the stripper receiving portion 23, the punch receiving portion 22 and the stripper receiving portion 23 may be moved to the position of the punch receiving portion 22 and the stripper receiving portion 23 according to the Figure 1 and then moves downwards to the replacement position 84. Alternatively, from the Figure 14Starting from the sunken position 82, the upward movement of the punch receiving part 22 and the stripper receiving part 23 can be realized by the reset element 26 until the set locking device is adopted, by which the replacement position 84 is adopted. Preferably, the locking device includes an operating lever assembly 86, which adopts the position according to the rotation movement. Figure 14 The rear position of the punch receiving portion 22 and the stripper receiving portion 23 is limited to limit the upward movement. Figure 16 The spacing of the punch receiving portion 22, the stripper receiving portion 23 and the die receiving portion 21 corresponds to the distance of the clamping element 57 from their receiving portion in the box body.
[0080] In order to remove the tool 35 from the equipment device 11, the drawer 74 is first opened. Subsequently, the empty box 34 is inserted into the drawer 74. Figure 17 . To remove the tool 35, the drawer 74 is closed. The clamping element 57 acts on the punch 36, the ejector 37, and the die 38 or the die carrier 39. The clamping force of the clamping element 57 is greater than the holding force of the releasable connecting element 31 in the receptacles 21, 22, 23. Subsequently, the drawer 74 is opened again and the cassette 34 with the clamped tool 35 is removed. The cassette 34 is now ready for operation and can be transferred to the tool magazine of the machine tool.
[0081] Figure 19 Show the basis Figure 1 A perspective view of the equipment 11 is shown, in which the machining tool 63 is being calibrated relative to the calibration ring of the punch 36. A holding device 88 is provided on the housing 12, in particular on the base plate 15, in which the clamping pin 41 of the punch 36 can be fixed. The machining tool 63 is oriented with the aid of an orientation aid 89 and can then be securely held on the punch 36 with the aid of the calibration ring.
