Abstract

In order to improve a machine tool comprising a loading device, in particular a press device, and several processing stations, wherein the processing stations each include a tool device that can be equipped with a tool, and at least most of the tool devices are each coupled to the loading device, it is proposed that at a processing station or in the case of several processing stations, the respective tool device comprises an individual control.

Description

The invention relates to a machine tool which comprises an application device and several processing stations.

The processing stations each include a tool device that can be equipped with a tool, and at least most of the tool devices are each coupled to the loading device.

The object on which the invention is based is to improve a machine tool.

According to the invention, the object is achieved with a machine tool mentioned at the outset, in which the respective tool device comprises an individual control in one processing station or in several processing stations.

Thus, in a processing station, the tool device comprises an individual control or, in the case of several processing stations, their respective tool devices each include an individual control, which in particular enables more flexible and easier handling of the machine tool and processing of a workpiece through it, for example compared to punching tools, which are essentially only path-controlled are.

In particular, a tool of the corresponding tool device can be individually controlled in each case by means of the individual control. In this way, for example, the corresponding tool can be controlled individually and independently of the other tools, so that the machine tool can be used more flexibly. In particular, the individual tool devices, preferably their tools, can be aligned relative to one another by the individual controls, so that the handling of the machine tool is simplified. For example, there is no need for manual or mechanical coordination of the individual tool devices with one another, for example with the aid of support surfaces, for the provision of an essentially equally high support for the workpiece to be machined at the different machining stations.

This particularly facilitates the construction and modification of the machine tool.

This is particularly advantageous if the tool devices are to be coordinated very precisely with one another, for example supports for the workpiece are to be coordinated very precisely to the same height, for example in order to carry out a substantially uniform punching or forming process with the machine tool.

Preferably, supports at the different block stations for individual processing sections of the workpiece to be processed are essentially planar with respect to one another. For example, in such machine tools it is necessary to keep differences in the alignment between the block stations smaller than 10 mm, in particular smaller than 5 mm, preferably smaller than 1 mm. In particular, tolerances of a maximum of one tenth of a millimeter, preferably of a maximum of approximately one hundredth of a millimeter, must be observed for the tool devices.

These requirements must be met in particular if the workpiece is arranged with the respective processing sections in several processing stations during processing.

For example, the alignment is necessary in order to at least avoid tilting of the workpiece and the resulting inaccurate machining of the same. For example, tilts in the size range of 1 mm or larger, in particular of a tenth of a millimeter and larger, are to be avoided.

With regard to the ability to equip the tool devices with a tool, no further details have so far been given.

In particular, the tool devices comprise a receptacle for a tool.

For example, in the case of one processing station or in the case of several processing stations, the tool device has a tool head. In some embodiments, the tool devices at all machining stations comprise a tool head. In particular, the respective tool head comprises a receptacle for a tool.

In the case of at least one processing station, the tool device preferably has a tool head with a tool. For example, tools are included in the receptacles of the tool heads at several machining stations. In some embodiments it is provided that the receptacles of all tool heads are equipped with one tool. In other embodiments it is provided that although some tool devices of processing stations can be equipped with a tool, these, in particular their tool head, are not equipped with a tool.

In particular, the one tool or the multiple tools are provided for machining a workpiece. Thus, the corresponding tool of a tool device is preferably arranged in alignment with a machining area of the tool device, with a workpiece to be machined being arranged in the machining area in a conventional machining process sequence with a machining section to be machined.

In particular, the tool devices can be equipped with a tool in a structurally simple manner by means of the tool head, and the tool head, which is in particular aligned with the machining area, enables simple machining of the workpiece.

For example, in some embodiments, a processing station or a plurality of processing stations are an empty station which, although it can be equipped with a tool and has a coupling point to the loading device, does not include a tool.

For example, one advantage of this can be seen in the fact that the machine tool can be equipped with a different number of tools depending on the machining process to be carried out and can therefore be used flexibly.

For example, a tool head defines a geometric tool head plane, preferably several tool heads, for example all tool heads, define a respective geometric tool head plane.

For example, the respective tool head extends essentially in its tool head plane.

In particular, it is provided that a tool of the tool head is or can be arranged, at least essentially, in the tool head plane.

In particular, it is provided in one processing station, preferably in several, for example in all, processing stations that the respective geometric tool head plane of the tool head of this tool device runs at least approximately perpendicular to an impingement direction of the loading device.

With regard to the individual controls in the one processing station or in the several processing stations, no further details have been given so far.

For example, the individual controls are designed differently at different processing stations, which in particular makes it possible to design the respective tool device with regard to specific requirements. In the case of several processing stations, the individual controls preferably have at least one identical feature, preferably several identical features. In particular, the individual controls in the multiple processing stations are essentially designed in the same way, which in particular makes the production of the machine tool simpler and more cost-effective.

Thus, it is provided in particular that the individual control in one processing station, preferably the individual controls in several, for example all, processing stations has / have one or more of the features explained below.

In particular, the individual control at the processing station is provided in addition to a control of the loading device.

In particular, the tool head of the corresponding tool device can be controlled by means of the individual control. One of the advantages of this is, for example, that a tool arranged on this tool head can be controlled directly as a result.

In preferred embodiments it is provided that the individual control includes a position control in at least one processing station. For example, this is a position control for the tool head. This makes it possible, for example, to bring the tool device, in particular its tool head, specifically into a machining position by means of the individual control.

It is particularly favorable if a position of the corresponding tool head relative to at least one other tool device, in particular the tool head of this other tool device, can be set and determined in at least one processing station by means of the position control.

It is thus possible, for example, to set the tool heads of different tool devices in different positions relative to one another and to fix them in these positions. In particular, this ensures that the individual tools of these tool heads do not act on the workpiece at the same time, and a sequence of the tools that act can thus be set during an application process. also An advantage can be that only some or some of the tools from the multiple processing stations act simultaneously on the workpiece and thus a total force that must necessarily be exerted by the loading device is smaller, since the individual forces to be exerted for the tools of the multiple processing stations do not become large Add the total force to be applied at the same time. In addition, another advantage in particular is that the tool heads with the tools can be controlled in such a way that they do not act on the workpiece at the same time and thus greater tolerances are possible when aligning the tool devices with one another and thereby at least reduce time-consuming and costly alignments of the tool devices relative to one another can be.

It is particularly advantageous if, in at least one processing station, a position of the corresponding tool device, in particular its tool head, can be adjusted and locked relative to the loading device by means of the position control, this position in particular being adjustable and lockable relative to a loading element of the loading device. This enables in particular an alignment of the tool device and preferably the tool on its tool head relative to the application device applying the necessary force, so that the machining of the workpiece can be controlled in a targeted manner by the tool device with the tool controlled in this way.

In particularly advantageous embodiments, it is provided that, in at least one processing station, the position of the corresponding tool device, in particular of its tool head, can be set and determined in a loading direction of the loading device by means of the position control. thus, for example, the tool device, in particular its tool head with the tool, can be aligned with respect to the effective direction of the loading device, that is to say its loading direction. In addition, such a positioning relative to the direction of application makes it possible to set the point in time at which the tool acts during an application process.

In particular, the tool device has a plurality of machining positions in at least one machining station, which can be controlled and thus adjusted and fixed by means of the individual control. In the case of several processing stations, in particular in the case of all processing stations with an individual control, the respective tool device preferably has several processing positions. It is particularly advantageous that the tool devices can be set individually due to the multiple machining positions, and use of the machine tool is thus more flexible.

In particular, the different machining positions differ in a different positioning of the tool head of the corresponding tool device.

For example, the machining positions of a tool device, in particular of its tool head, are arranged one behind the other in the direction of application.

It is particularly favorable if the machining positions of different tool devices, in particular of their tool heads, differ relative to the direction of application. The advantages mentioned above are transferred in a particularly favorable manner.

In some embodiments, the different processing positions are individual separate positions, in other embodiments the processing positions are arranged essentially continuously and can be controlled at least in one area.

As an alternative or in addition, it is particularly advantageous if the individual control includes a force control in at least one processing station. In particular, this is a force control for the tool head of the tool device of this processing station. Preferably, at each processing station which is provided with an individual force control, the force exerted by the tool head with a tool on the workpiece can be individually adjusted and determined at least in a range around the force provided by the application device.

In particular, it is provided that, in at least one processing station, its tool device has at least one state that is force-coupled to the loading device. In particular, in a force-coupled state, the tool head of the one processing station or the respective tool heads of the several processing stations are force-coupled with the loading device in a force-coupled state. In this way, at least in the force-coupled state, a force provided by the loading device is provided to the processing station, in particular its tool device, preferably the tool head of the same with the tool, for processing the workpiece.

In some advantageous embodiments, precisely one force-coupled state is provided, in which, for example, the force provided by the application device is simply passed on to the tool device and in particular to the tool head. A structurally simple implementation is thus preferably made possible.

In other preferred embodiments, several force-coupled states are provided, in particular in the several force-coupled states the force provided by the application device being amplified and / or reduced to different degrees. In this way, in particular, an expanded force control is provided and flexibility of the machine tool for various machining processes is increased. For example, in a force-coupled state, the force provided by the application device is passed on unchanged to the tool device, in particular to its tool head, and in at least one further force-coupled state, the provided force is amplified by the individual control and / or the provided force in at least one further force-coupled state reduced by the individual control.

It is particularly favorable in some embodiments if, in at least one processing station, its tool device has at least one state that is force-decoupled from the application device. In particular, it is provided that the corresponding tool device, in particular its tool head, is force-decoupled from the application device at the one processing station or at the multiple processing stations in the force-decoupled state. In this way, for example, machining of the workpiece by the corresponding tool of the machining station can be controlled in a more targeted manner. In particular, the corresponding tool device can be put into the at least one force-decoupled state during an application process after machining has been carried out by the tool, so that the machining of the workpiece in the corresponding machining station is ended even if the application process is continued. For example, when a necessary force to be exerted, for example a required pressing force, is reached, the tool device can be put into the force-decoupled state and thus this and also its tool head can be switched to a force-free state. In particular, machining with a set maximum force exerted is thus made possible.

In particular, it is provided that in one processing station, preferably in several, for example in all, processing stations with an individual control, the individual control is set up to put the tool device of the corresponding processing station in the at least one force-coupled state. With this processing station or with these processing stations it is preferably provided that their individual control is set up in order to also put the corresponding tool device into the at least one force-decoupled state.

Finally, it is particularly preferred if the respective individual control at this processing station or these processing stations is also set up in such a way that the corresponding tool device is also put into the further force-coupled and / or force-decoupled states, if any.

For example, an advantage of this is that by means of the respective individual control, the tool device can easily be put into a force-coupled and in particular also force-decoupled state and, for example, into other states, thereby enabling flexible use of the respective tool device.

At least one processing station preferably has a coupling device for coupling the tool device to the loading device. In particular, at the one processing station or at the several processing stations, the respective tool device thereof is coupled to the application device by means of the respective coupling device. The tool head of the corresponding tool device is preferably coupled to the loading device by means of the coupling device. In particular, the coupling takes place by means of the coupling device to the loading element of the loading device.

In particular, the coupling device provides a force-coupled coupling between the tool device and the loading device, which is particularly effective at least in the force-coupled states. Thus, force is advantageously transmitted from the application device to the tool device via the coupling device.

It is particularly advantageous if the coupling device is activated by the individual control in at least one processing station. In this way, it is achieved in a favorable manner at the one processing station or at the several processing stations that the tool device, in particular its tool head, can be controlled in a simple manner by the individual control by means of the coupling device and, for example, can be set and locked in different states and / or positions .

It is particularly advantageous if, in at least one processing station, the tool head of its tool device is coupled to the loading device, in particular its loading element, by means of a coupling device controlled by the individual controller. For example, simple and flexible control of the tool head, for example moving it into different positions and / or states, is thus made possible in a simple manner.

In some advantageous embodiments it is provided that the respective tool device has an individual control at all processing stations. This provides a machine tool that can be used very flexibly, for example, since the respective tool device at each of the processing stations can be controlled by the individual control, in particular as explained above, and can be aligned and / or placed in different positions and / or states, for example.

In other preferred embodiments, however, it is provided that, in the case of a processing station or a plurality of processing stations, the respective tool device does not include an individual control. For example, one advantage of these embodiments is that not every tool device is equipped with an individual control and thus the machine tool can be manufactured more cost-effectively.

In some advantageous embodiments it is provided that, in at least one processing station, the tool head is rigidly coupled to the loading device, in particular to its loading element. In particular, such a rigid coupling is provided in machining stations without individual control and through the rigid coupling the force provided by the loading device is transmitted in a structurally simple manner to the tool head for machining the workpiece.

For example, in some favorable embodiments it is provided that the tool devices of at least two processing stations are coupled to one another in a blocked manner. In the case of these several processing stations, their tool heads are preferably coupled to one another in a blocked manner. In particular, the tool devices that are coupled to one another in a blocked manner are precisely aligned with one another and, through their blocked coupling, this precise alignment with one another is at least substantially maintained over a large number of loading operations and customary machining process sequences. In particular, a realignment of these tool devices, which are coupled to one another in a blocked manner, is usually only possible by converting the machine tool. For example, the blocked coupling is provided by a rigid connection to one another. An advantage of the mutually blocked coupling of at least two tool devices can be seen in the fact that they are aligned with one another and, due to the blocked coupling, this alignment is maintained over a number of loading operations and machining process sequences. It is thus provided in particular that at least most, preferably all, processing stations are coupled to one another in a blocked manner without individual control.

In contrast to known machine tools, in which all tool devices are coupled to one another in a blocked manner, it is provided in machine tools according to the invention that at least one tool device comprises an individual control as explained above and below.

In particular, it is provided that an individual control is provided for machining stations whose tool device includes a tool that requires precision, and no individual control is provided for machining stations whose tool device includes a tool for machining with larger permitted tolerances. In this way, the advantages of individual control are achieved, for example, as explained above, in the case of tool devices with tools that require precision and, on the other hand, a cost-effective solution is provided since individual control is dispensed with in tool devices for which larger tolerances are permitted. For example, the forming tools, in particular the embossing tools and / or pressing tools, are to be regarded as tools that require precision and, for example, greater tolerances are permitted in the case of cutting tools, in particular in the case of a cutting tool and / or punching tool.

In some favorable embodiments it is provided that in at least two processing stations the tool head plane of their tool heads coincide at least approximately. This is provided in particular in the case of the tool devices which are coupled to one another in a blocked manner, because with these it is typically important that their tools at least substantially simultaneously process the workpiece and are in engagement with it. For this it is typically necessary that the tool devices of these processing stations are completely closing, that is to say blocking, coordinated and aligned and coupled to one another.

With regard to the design of the individual control, no further details have been given so far.

In some preferred embodiments, the individual controls are designed differently at different processing stations. For example, this offers the advantage of adapting the individual control to specific requirements at the respective processing station. In other particularly preferred embodiments, it is provided that the individual controls have a common feature or a plurality of common features in several processing stations, for example in all processing stations, and in particular are designed essentially the same. In particular, an advantage of this is that essentially the same individual controls are used, and thus the design and manufacturing costs for the machine tool are lower and the machine tool can thus be manufactured more cost-effectively.

It is therefore advantageous if the individual control of a processing station, preferably the individual controls of several processing stations, for example the individual controls of all processing stations, has / have one or more of the features explained below.

In some favorable embodiments, the individual control comprises an electrical control. For example, an electrical control allows a variety of control options.

In some preferred embodiments, the individual control is at least partially designed mechanically and thus comprises, for example, a mechanical control element or a plurality of mechanical control elements. For example, the advantages of this are that the mechanical control is structurally simple and inexpensive to manufacture.

In addition, the mechanical control elements, in particular, can be designed to be stable and resilient, so that a reliable and large control that can withstand the effects of forces can be provided.

In particularly advantageous embodiments, it is provided that, in at least one processing station, the individual control is at least partially a hydraulic control. In particular, the individual control includes a hydraulic control element or a plurality of hydraulic control elements. For example, the individual control is designed as a hydraulic control.

One advantage of the hydraulic control is, for example, that it can be designed to be stable and reliable even for large impact forces.

In particular, a hydraulic control also enables a wide variety of control options and thus offers flexible control options for individual control, for example in order to move the tool device into different positions and / or states.

For example, the hydraulic control includes a hydraulic cylinder, which is controlled in particular via a hydraulic unit as part of the individual control. In particular, the hydraulic cylinder is part of the coupling device between the tool device and the Beaufsch lagu ngsvorrichtu ng.

A force control via the hydraulic control can be enabled particularly favorably. In particular, a hydraulic cylinder filled with hydraulic medium provides a force coupling, this being effective in particular in a force-coupled state. By activating the hydraulic cylinder, the coupling can easily be put into a force-decoupled state. Variable force control is also possible by means of the hydraulic control, for example by controlling the hydraulic pressure, in particular in the hydraulic cylinder. In addition, a position control can alternatively or additionally be implemented by means of a hydraulic control, for example by setting a stroke of the hydraulic cylinder accordingly.

In particularly advantageous embodiments, it is provided that the individual control is a combination of, for example, the control types mentioned above. For example, the individual control is an electro-hydraulic control. In other favorable embodiments, the individual control comprises mechanical and / or electrical and / or hydraulic control elements.

In particular, it is provided that the individual control is provided in the one processing station or in the several processing stations in addition to a control of the loading device.

With regard to the further configuration of the processing stations, in particular of their tool devices, no further details have so far been given.

In particular, it is provided that a respective processing area is defined for several processing stations, in particular for all processing stations. For example, the machining area is defined by the respective tool device. In a conventional machining process sequence, a machining section of the workpiece to be machined is arranged in the machining area and can be machined by the tool in this machining area. In particular, the tool is arranged in the tool device in such a way that it is aligned with the machining area.

In favorable embodiments it is provided that the processing areas of at least several processing stations, for example all processing stations, essentially define a common geometric processing plane. This makes it possible, for example, that a larger workpiece can be arranged in a simple manner for processing individual processing sections with these in the respective processing areas of different processing stations. In particular, the common geometric processing plane runs through the processing areas of the at least several processing stations. For example, the processing areas of the at least several processing stations are essentially located in the common geometric processing plane and / or are defined adjacent to the geometric processing plane.

It is advantageous if the common geometric processing plane is aligned at least approximately perpendicular to the direction of application of the application device. Thus, in particular, a workpiece can be arranged in the machining areas and is acted upon and machined by the tools by means of the application device at least approximately perpendicular to the alignment in the machining regions along the machining plane.

In particularly favorable embodiments, it is provided that in one processing station, preferably in the case of several processing stations, in particular in all processing stations, the tool device of the respective processing station comprises a support, the support being provided for a workpiece to be processed. In particular, the support comprises a support surface for the workpiece to be processed, in particular its processing section to be processed. This enables, for example, a reliable and stable arrangement of the machining section on the support in the tool device.

In particular, it is provided that the machining area of a tool device is defined between the support and the tool head of this tool device. It is thus ensured, for example, that the machining section arranged on the support can be machined in a simple manner by the tool head with its tool. In particular, it is provided that the machining area of the tool device is defined adjacent to the support surface.

Provision is preferably made for the support surfaces to run at least substantially in a common geometric support plane in the case of a plurality of processing stations, for example in all processing stations. This enables and preferably ensures, for example, that a workpiece to be processed, in particular with a flat support side, can be arranged precisely on the multiple support surfaces in the multiple processing areas. In particular, the risk of the workpiece tilting can thus at least be reduced and the workpiece can thus be machined more precisely. It is advantageously provided that the common geometric support plane runs at least approximately perpendicular to the direction of application.

It is preferably provided that in one processing station, advantageously in several, for example all, processing stations, the support surface runs at least approximately parallel to the common geometric processing plane. It is particularly advantageous if the common support plane and the common processing plane are oriented at least approximately parallel to one another. For example, this is also beneficial for the secure arrangement of the workpiece to be machined and the precise machining of the same.

With regard to the tools in the tool devices, no further details have been given so far.

In particular, the tools of the tool devices are tools for linear machining of the workpiece. In particular, a linear coupling between the loading device and the tool heads with these tools is sufficient. For example, an advantage can be seen in the fact that the tools can machine the workpiece essentially in the linear direction of application of the application device and can machine them in a conventional machining process sequence.

In preferred embodiments, it is provided that, in the case of a processing station or a plurality of processing stations, the respective tool device comprises a forming tool and / or a separating tool and / or a joining tool. For example, in the case of one processing station or in the case of several processing stations, the tool is an embossing tool and / or a leveling tool and / or pressing tool and / or a cutting tool and / or a punching tool.

In particular, the tools include a processing part, for example a cutting edge and / or an embossing die and / or a punch. The machining part is preferably arranged in the tool head plane of the corresponding tool head, in particular in such a way that the linear machining direction of the tool runs at least approximately perpendicular to the tool head plane.

In particular, the machine tool, which is preferably equipped with one or more of the above-mentioned tools in the corresponding tool devices, is a forming machine for forming a workpiece. As an alternative or in addition, it is provided that the machine tool is a manufacturing machine for machining a workpiece through to manufacturing a component.

With regard to the loading device, no further details have been given so far.

In particular, the loading device is provided and designed to provide the tool devices with a force necessary for machining the workpiece.

Provision is preferably made here for the application device to act on the tool devices coupled to it, specifically in particular in the direction of application. In particular, the direction of application is a linear direction of application and is preferably aligned at least approximately parallel to the linear machining direction of the tools. For example, this enables a structurally simple structure of the machine tool with the loading device and the tool devices and precise machining of the workpiece by them.

The loading device preferably comprises at least one loading element to which the tool device of a processing station, preferably the tool devices of several processing stations, for example all processing stations, are coupled for loading and, for example, are arranged. It is particularly preferred if a common loading element of the loading device is provided and each of the tool devices coupled to the loading device are coupled to this common loading element. One advantage of this is, for example, that a simple force transmission is made possible by means of the at least one loading element and, in particular, the necessary force is provided to all coupled tool devices by means of the common loading element.

In particular, it is provided that during an application process the at least one and / or the common application element is transferred from an initial position to an end position and the coupled tool devices are applied during the transfer.

It is particularly favorable if the at least one and / or the common loading element can be moved linearly in the loading direction. It is particularly favorable if the loading element is movable relative to the supports of the tool devices and / or is movably arranged in the loading device. For example, this enables precise application of the tools and thus precise machining of the workpiece arranged on the supports.

In some preferred embodiments it is provided that the application device is a press device which comprises a press. The press provides the necessary power. For example, the at least one and / or the common loading element is a ram of the press.

For example, the invention makes it possible to use a loading device in the machine tool that provides a smaller overall force, i.e. in particular a press with lower power, through the use of one or more individual controls, as explained above, than in essentially the same machine tool , in which no processing station has an individual control.

Above and below, the indication that at least most of the elements of a multiplicity of elements have a feature is to be understood in particular that at least more than half of the elements of this multiplicity of elements, preferably at least 75%, for example more than 85% of the elements , have the corresponding characteristic. It is preferred if at least most of a large number of Elements should have a feature that at most 3 of the elements, in particular at most one element, for example none of the elements, of this multiplicity of elements do not have this characteristic and all other elements of this multiplicity have the corresponding characteristic.

Above and below, the indication that a value should be realized at least approximately is to be understood, in particular, that technically conditioned and / or technically irrelevant deviations from the indication are also included. For example, deviations of up to 15%, preferably of up to 10%, in particular of up to 5%, from the specified value are also included. In particular, two directions and / or two planes are at least approximately parallel to one another if an angle between them is at most 20 °, in particular at most 15 °, preferably at most 10 °, for example at most 5 °.
