- a machine tool is used to manufacture and process workpieces using tools.
- machine tools are here for example
- Sheet metal working machines in particular bending machines or presses such as
- Press brakes viewed. In the following, for reasons of clarity, reference is made to press brakes.
- Machine axes and the quality of the produced bent parts sinks. In addition, the value of the machine is reduced.
- Machine tables and stop fingers can not be corrected by readjusting - such components must be replaced. Also in this case will be before the
- the invention is based on the object to avoid the disadvantages of the prior art and to provide an improved component for a machine tool, an improved machine tool or an improved method for detecting wear.
- the component according to the invention for a machine tool includes a
- Component main body and at least two arranged on this layers for
- Wear region of a component of the machine tool are applied and wherein at least one of the two layers, a signal layer for identifying the
- the identification can be visual, for example by color
- the wear detection can be finely graded.
- the component according to the invention for a machine tool has the advantage that a predictive maintenance and a consistently high quality machining such as bending quality are possible.
- the at least two layers are layers which, for example, differ according to their composition from that of the component or its basic body. For example, after completion of the component, the layers may be in one or more additional steps
- the consumable layer in the initial state is arranged relative to the component main body in each case relatively outside and the signal layer in each case relatively between the consumption layer and the component main body and / or a layer pair of a further consumption layer and a signal layer.
- the component is a tool, a machine table and / or a stop element.
- all wear-prone parts can be equipped with the wear detection layers.
- the component is a wearing part of a bending machine, in particular a tool, a machine table and / or a stop element.
- all wear-prone parts can be equipped with the wear detection layers.
- the wear detection proposed here is particularly suitable for a bending machine or those components of a bending machine, which are in contact with the workpiece to be bent. Because these components are subject to wear and are also visible to the user or are handled by him, for example when a tool change.
- the signal layer is a material with low
- this mostly internal signal layer can also have wear-minimizing properties or sliding properties.
- the signal layer is color-coded and differs in color from the one or more consumption layers and / or the component base body. After the removal of the outer layer, or the consumption layer, the signal layer, ie the underlying layer visible and the operator clearly represented by the signal color. The operator is thus given a clear indication that the wear limit has been reached, the quality of the produced
- a possible color variant would be, for example, the use of the traffic light colors green, yellow, red.
- the currently translucent color can be transferred manually or automatically into the machine control in order to adjust the delivery of the machine axes according to the degree of wear.
- the user can directly, ie without a controller, detect the wear.
- one of the two layers (wear layer and
- Layers electrically insulating material for insulating the electrically conductive material are usually made of each function-optimized steel grades and are electrically conductive.
- An advantageous increase in the service life of these components can be achieved by applying various coatings which possibly influence the conductivity of the components but generally do not prevent them.
- a component coating with an insulating and optionally wear-minimizing coating allows the creation of a circuit with this insulating layer as a "switch.” The presence of the layer then meets the requirement of an intact reference surface and an open circuit.
- Damage to the insulation leads to a change in shape of the affected component and at the same time to a closed circuit. This change can be determined and used for corresponding reactions. It is understood that the electrically conductive layer is surrounded on both sides of the layer (ie inwardly and outwardly) by electrically insulating material, with the exception of possible contact points for closing the circuit or for electrical signal transmission.
- a transponder which is set up to output a signal if one of the two layers is damaged.
- the determined signs of wear can be clearly assigned to a removable component.
- Such components are for example on press brakes mainly bending tools, so punches and dies. These bending tools are freely combinable and product specific. A constant change of these components is typical. Therefore, it is advantageous to be able to differentiate between these components. It can also act as the outer layer already as a signal layer, the damage is signaled by the transponder.
- a machine tool according to the invention is set up for processing
- a circuit is applied to the component, wherein the electrically conductive material of the at least one layer functions as a switch.
- a voltage measurement can take place in the circuit via a load. Due to the wear of the current-carrying layer, the resistance and thus the voltage can change. Upon further wear or severing the circuit can be opened, which can also be detected.
- a control is provided, which is connected to the circuit, and that the control is set up, based on the
- Circuit determined wear in the control of the machine tool For example, corrections in the control of the machine axes and / or the feed can be made automatically.
- each of the electrically conductive layers is connected to electrically conductive material with a circuit.
- further lifetime predictions are possible, for example with an automatic and periodic insulation measurement or the described orders of several layers on the wear-stressed components.
- alternating insulating and electrically conductive hard coatings are applied to the components. The progressive wear of the components opens or closes the applied circuit. A count of this process, the shift, or
- Machine tool as described above comprises the steps:
- Machine components can lead to automatic calibrations and the
- Stop fingers are repositioned by the backgauge and continue to be used.
- Progressively worn tools may be classified and appropriately assigned using appropriate means (eg, data matrix codes, or the like): Similarly worn tools are recognized by the machine and used together for a product - the machine axis (in this case, the upper jaw) can correct relative value and produce a constant bending angle. Otherwise, the same advantages and modifications apply as previously described.
- the detection of an interruption is carried out continuously, wherein an electrically conductive workpiece closes the circuit.
- the layer thicknesses can then be determined continuously throughout the entire machining process.
- the detection of an interruption is carried out by bringing the component for closing the circuit into contact with an electrically conductive part of the machine tool.
- An initialization phase requires reconnecting to a conductive, stationary material on the machine.
- the component to be tested for wear is then connected to the machine axis
- This intermediate element may be, for example, an electrically conductive brush.

- FIG. 1 shows a schematic front view and a plan view of a component 100 having a component core or component base body 110 and optical components mounted thereon
- the component 100 may be a wearing part of a
- Bending machine in particular a tool, a machine table and / or a
- Stop element be like a stop finger. Accordingly, the wearing part of a bending machine can have a basic body 110 with optical equipment mounted thereon
- Wear detection 120, 130 include.
- the component 100 is provided with an outer hard material layer or consumption layer 130 in accordance with the intended use.
- the material used here is, for example, PVD and / or CVD Hard material layers or materials such as titanium nitride in question.
- the layer thickness is selected with regard to the application and the expected component wear.
- the layer thickness is advantageously 1 to 10 micrometers and more preferably 1 to 20 micrometers. In addition, larger layer thicknesses can be used.
- the layer thickness depends on the application method and the subsequent adhesion to the component 100 or the underlying layer.
- a signal layer 120 was applied below the outer consumption layer 130. This signal layer 120 is distinctly different in color from the consumption layer 130 and is advantageously applied in a signal color.
- the color is due to the applied material, e.g. TiN is golden yellow, and / or due to variations in application technology.
- the entire layer is accordingly made of a colored material, that is as long as there are still parts of the layer, the color is still clearly visible.
- this inner signal layer 120 as well as the consumption layer 130
- the signal layer 120 is applied to a component base body 10 of the component 100.
- the signal layer 120 and also the consumption layer 130 can be applied selectively in a wear region of the component 100, such as a surface, edge, three-dimensional region, etc. Likewise, as shown, layers 120 and 130 may completely cover component 100.
- FIG. 2 shows a schematic front view and top view of a worn-out component 100 with optical wear detection.
- the outer consumption layer 130 is continuously removed by the contact with the workpiece. This results in a region 130a in which the outer consumption layer 130 is partially removed, ie worn. As already described, this changes the geometry of the component 100, which wears component 100. After the complete removal of the outer consumption layer 130, the inner, ie the underlying signal layer 120 visible (which is different from the color of the
- Abrasion can be used different layers with correspondingly assigned colors. The user can thus be shown the degree of wear and further steps can be taken. A possible color variant would be, for example, the use of the traffic light colors green, yellow, red.
- the consumable layer 130 may have the color green, the signal layer 120 the color yellow, and the component main body 110 the color red.
- the signal layer 120 may have a color, for example, red.
- Figure 3 shows a perspective view of a bending machine 300 with a component with wear detection as a stop finger 310.
- Stop fingers 310 of bending machines 300 allow correct leg lengths of the bending parts by stops and positioning of the sheet relative to the bending line.
- the optimized finger contours are subject to plate wear and pivoting during the bending process a high wear and wear off. Consequently, the bent parts can then no longer be positioned correctly.
- Methods of heat treatment of the abutment fingers 310 are already known for minimizing wear.
- the components are subsequently coated, for example, with physical and / or chemical vapor depositions.
- FIG. 4 shows a schematic illustration of a component 400, for example a
- the component 400 is connected to an electrical circuit 410 or part of the electrical circuit 410.
- the electrical circuit 410 includes a supplier such as a voltage source and a load 430, at which electrical parameters such as voltage or current can be measured.
- the component 400 then functions as a switch. In other words, that is Component 400 once a conductor and once an insulator. Whether the circuit 410 is closed or not is monitored and displayed via a suitable load 430.
- the component 400 is provided with a plurality of alternating respectively insulating layers 440 and electrically conductive layers 450 during manufacture.
- the electrically conductive layers 450 comprise electrically conductive material or consist entirely of this material. These layers 440, 450 are executed application-related and can be provided in addition to the wear minimization also with sliding properties. Most DLC coatings (diamond-like-carbon, diamond-like carbon) achieve good sliding properties, but physical vapor deposition (PVD) coatings are also advantageous compared to untreated or heat-treated materials.
- the layer thickness is determined precisely by the manufacturing process of the component 400. In this case, at least one electrically conductive layer and an insulating layer must be present. It does not matter in which order the layers 440, 450 are applied.
- the thicknesses of the applied layers 440, 450 may vary here, advantageously a thickness in the absolute value of the tolerated wear.
- the respective thicknesses must be known and stored in a controller, for example in the machine control.
- the finger is - a connection point except 460 - insulated on all sides and is thus no longer electrically conductive.
- an electrical voltage is applied to the machine, with e.g. the anode at the conductive point of the finger and the cathode at the machine table, or the die.
- the positioning of bending parts in the bending process which consists predominantly of conductive materials, does not lead to a closed circuit, since the insulating hard material layer of the finger is still completely intact.
- Increasing wear on the finger removes the insulating layer 440 until the circuit 410 is closed.
- suitable evaluation mechanisms normally the machine control - the contact is established and measures are taken. Ideally, the tolerated deviation is now reached and the finger would have to be exchanged.
- a wearing component 400 will alternately open and close the circuit 410.
- the number of these processes and the layer thickness value allow an accurate conclusion on the degree of wear of the component 400 and are in the
- Machine control stored and processed.
- the continuously changing geometry of the component 400 can be included in the production process and the affected Machine axis to be adjusted in the feed.
- the affected machine axis is then always adjusted by the amount of the worn layer.
- the inspection of the components 400 can take place continuously in the bending process or as an initialization.
- the electrically conductive workpiece 400 is used as part of the circuit 410 and included in the test.
- the layer thicknesses can then be determined throughout the bending process.
- This intermediate element is an electrically conductive brush.
- the advantage here is the avoidance of an unwanted collision (touch area), as well as the coverage of a large inspection area (no line contact). Wherein a line contact or sometimes a point contact may be desired.
- the brush allows the scanning of a 3D contour, but this can complicate the detection as the wear of the component progresses. To simplify this process, it may be advantageous - exclusively or additionally - to monitor a point or a line.
- the principle of wear detection by conductivity is not limited in principle to an electrical conductivity.
- a conductivity for electromagnetic waves e.g. Light, or magnetic flux can be exploited.
- the circuit 410 is closed. If the outer insulation layer 440 is still intact there is no signal at the load 430. There is no message to the machine control.
- the circuit 410 is closed. Now the outer one Isolation layer 440 is no longer intact, the conductive layer 450 is outside, it is a signal at the load 430. There is therefore a message to the machine control. There is a clearing of the new component geometry in the form of a subtraction of the amount of the outermost layer 440 and a recalibration of the relevant
- Machine axis or machine axes are Machine axis or machine axes.
- the circuit 410 is closed. Now, the conductive layer 450 is no longer intact, the next insulation layer is outside, it is therefore no signal at the load 430. There is therefore a message to the machine control.
- the new component geometry is calculated in the form of a subtraction of the amount of the conductive layer 450 and a recalibration of the relevant component
- Machine axis or machine axes are Machine axis or machine axes.
- the absolute frequency of the measurements depends on various factors and varies.
- the conductive layers 450 can each be checked with their own circuit, then a more accurate localization of the interruption (damaged area) and thus a differentiated wear statement is possible. A further improvement results from a two- or three-dimensional layer structure. Complex geometries can be monitored.
- the component 400 is further equipped with a transponder 470 configured to output a signal when one of the two layers 440, 450 is damaged.
- the RFID transponder 470 is attached to the tool 400 and marks it.
- the transponder 470 is coupled to the described layer structure and in each case sends a signal if a layer has been damaged.
- Machine control can thus also correct the feed in accordance with the changed geometry. Also conceivable are proposals for an advantageous denomination of the components: evenly worn components are preferably combined.
- the unambiguous assignment of the tools can equally be done by means of a code (QR code, bar code, 2D code, numerical input, etc.). The code is read out appropriately and the data is transmitted to the machine control or entered by the operator.
