DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

First of all, it is to be noted that in the different embodiments described, equal parts are provided with equal reference numbers and/or equal component designations, where the disclosures contained in the entire description may be analogously transferred to equal parts with equal reference numbers and/or equal component designations. Moreover, the specifications of location, such as at the top, at the bottom, at the side, chosen in the description refer to the directly described and depicted figure and in case of a change of position, these specifications of location are to be analogously transferred to the new position.

FIG.1shows an exemplary embodiment of a workpiece processing machine1in the form of a bending machine2, in particular a press brake3. The press brake3is provided for processing, in particular for bending, a workpiece4. The press brake3has a fixed table beam6oriented perpendicularly to a standing surface5. For processing workpieces4, the shown press brake3comprises a press beam7, which is adjustable and/or displaceable relative to the table beam6in the vertical direction by means of driving means8, for example hydraulic cylinders9.

In the press brake3according to the exemplary embodiment shown inFIG.1, the processing and/or forming of a workpiece4is effected by means of a lower bending tool10and an upper bending tool11. In this process, the lower bending tool10, for example a so-called bending die, may be arranged in a lower tool holder12of the table beam6. An upper bending tool11and/or a so-called bending punch may be arranged in an upper tool holder13of the press beam7.

Usually, the bending tools10,11are arranged and/or held in the tool holders12,13so as to be replaceable, so that for a respective processing and/or forming of the workpiece4, correspondingly suitable bending tools10,11can be selected and/or used. Of course, it is also possible that in each case, multiple lower bending tools10and upper bending tools11are arranged in the tool holders during operation of the press brake3, for example in order to be able to carry out different bending operations on a workpiece4in successive forming and/or bending operations. For the sake of clarity, the exemplary embodiment according toFIG.1shows only one lower bending tool10and one upper bending tool11.

For controlling the displacing and/or adjusting movements of the press brake3, a control device14may be provided. As adumbrated inFIG.1, the control device14may comprise multiple components, for example processors and/or computer components, input means for inputting control commands, output means for displaying information, etc. Moreover, it is also possible that the control device14is connected to further control components, for example with mobile input and output means, via a network or via the internet.

As can further be seen inFIG.1, it is provided that one or multiple graphic displays15for displaying information are arranged on the displaceable press beam7of the press brake3. In this regard, the graphic display15is arranged on the displaceable press beam7such that it is displaceable together with the displacement of the press beam7in the vertical direction. In particular, it may be provided that the graphic display15is coupled to the control device14.

FIG.2shows a perspective view of a first exemplary embodiment of the press beam7of the press brake3, wherein again, equal reference numbers and/or component designations are used for equal parts as before inFIG.1. In order to avoid unnecessary repetitions, it is pointed to/reference is made to the detailed description inFIG.1preceding it.

As can be seen fromFIG.2, it may be provided for that two graphic displays15serving to display information are arranged in the press beam7.

In the representation according toFIG.2, only one of the two graphic displays, namely the graphic display15on the left of the image, is inserted and the right graphic display15is not shown for the sake of clarity. This makes a recess16in the press beam7visible, which serves to accommodate the graphic display15.

As can further be seen inFIG.2, it may be provided that the recess16has a tiered design and has a first recess tier17, a second recess tier18, and a third recess tier19. Moreover, it is of course also conceivable that particularly the second recess tier18has further tiers. The individual recess tiers17,18,19serve to accommodate different components of the graphic display15.

As can further be seen inFIG.2, it may be provided that the recess16, in particular one of the recess tiers17,18,19has a rounding20having a rounding radius21on one corner.

Moreover, it may be provided that a cover plate22, which serves to protect the graphic display15, is formed in front of graphic display15. The side of the press beam7facing the viewer ofFIG.2, in which side the graphic displays15are arranged, is referred to as the front side23. The side of the press beam7facing away from the viewer ofFIG.2is referred to as the rear side24. As can be seen inFIG.2, it may be provided that the front side23of the cover plate22forms an indentation relative to a surface25of the press beam7. In other words, the cover plate22is accommodated inside the recess16and thus does not project relative to the surface25of the press beam7.

FIG.3shows a first exemplary embodiment of a display module26in which the graphic display15is arranged. In the perspective view according toFIG.3, the display module26is shown with a view of the front side23.

FIG.4shows he display module26with a view from the rear side24.

InFIG.5, the display module26is shown in a sectional view according to line V-V fromFIG.4.

FIGS.3to5show further views of the display module26, wherein again, equal reference numbers and/or component designations are used for equal parts as in the respectively preceding figures. In order to avoid unnecessary repetitions, it is pointed to/reference is made to the detailed description in the respectively preceding figures.

The individual components of the display module26is described with the aid of a combination ofFIGS.3to5.

As can be seen fromFIGS.3to5, it may be provided that the display module26comprises a covering screen27, on which the cover plate22may be accommodated. On the rear side of the cover plate22, a touch sensor28may be arranged, which may serve for inputting commands. The touch sensor28may be attached directly on the cover plate22by means of a materially bonded connection, in particular be attached to the rear side24of the cover plate22.

Moreover, it is conceivable that the cover plate22is attached to the covering screen27by means of a materially bonded connection, in particular an adhesive connection. The cover plate22may be formed of a shatterproof and transparent material, such as a glass. Moreover, it may be provided that the cover plate22is attached to the frame38by means of a double-sided adhesive tape53.

As can be seen fromFIG.3, the graphic display15has a display height29and a display width30. The cover plate22has a cover plate height31and a cover plate width32. The covering screen27has a screen height33and a screen width34. Moreover, a screen opening35is formed in the covering screen27, which screen opening35has an opening height36and an opening width37.

The cover plate22and/or the graphic display15underneath it is visible through the screen opening35of the covering screen27. For this purpose, it is necessary that the cover plate22is formed of a transparent material. The covering screen27may be formed of a metallic material. In particular, it may be provided that the covering screen27is formed from a sheet metal part.

As can be seen particularly well from a combination ofFIGS.3and5, it may be provided that the cover plate height31is less than the screen height33. Moreover, the cover plate width32may be less than the screen width34. This may help achieve that the covering screen27protrudes laterally relative to the cover plate22. This protrusion may serve the clean accommodation of the display module26in the recess16.

Moreover, it may be provided that the opening height36is less than the cover plate height31, and the opening width37is less than the cover plate width32. Due to this measure, the cover plate22may abut the covering screen27and thus be attached to the covering screen27in a materially bonded manner. In particular it may be provided that the dimension ratios of the opening height36and/or opening width37and the cover plate height31and/or cover plate width32are selected such that the screen opening35is covered by the cover plate22on all sides by between 1 mm and 30 mm, in particular between 5 mm and 25 mm, preferably between 10 mm and 15 mm.

Moreover, it may be provided that the opening height36is greater than the display height29, and the opening width37is greater than the display width30. This entails the advantage that the machine operator can utilize the full display dimensions in case a touch display is present. If the opening height36were to be of the same size or less than the display height29and/or the opening width37of the same size or less than the display width30, the edge region of the display could no longer be used, as the machine operator would not be able to carry out touch inputs here.

As can be seen from a combination ofFIGS.4and5, it may be provided that the display module26comprises a frame38, which laterally houses the graphic display15. The frame38may directly adjoin the covering screen27on its front side and be closed by the covering screen22. On the rear side of the frame38, a module rear wall39may be formed, which also closes the frame38. The graphic display15can thus be accommodated in a receiving space40, which is bounded on the front side by the cover plate22, on its side by the frame38, and on the rear side by the module rear wall39. By means of this design, the graphic display15can be protected from environmental influences and/or be safely accommodated in said receiving space40.

Moreover, it may be provided that the frame38comprises four frame elements41which form the rectangular frame. The individual frame elements41may be formed, for example, as a formed sheet metal part. Moreover, it may be provided that fastening supports42are arranged on the covering screen27, which fastening supports42serve to fasten the frame elements41and/or the frame38to the covering screen27. The fastening supports42may be designed in the form of threaded pins, which may be attached to the covering screen27. Moreover, it may be provided that the fastening supports42, in particular the threaded pins, are coated with a protective coat in order to avoid damage to the cover plate22. In this regard, the protective coat may be formed of a material that is soft compared to the fastening supports42, such as a plastic material or rubber.

Moreover, it may be provided that recesses are formed in the frame38and/or in the individual frame elements41, through which recesses the fastening supports42may protrude, and wherein the frame38and/or the frame elements41may be attached to the covering screen27by means of fastening elements43, such as nuts, which cooperate with the fastening support42. Moreover, it may be provided that the individual frame elements41have an L-shaped clamping limb44, by means of which the cover plate22can be pressed against the covering screen27and thus be clamped. This may serve the additional attachment of the cover plate22on the covering screen27.

The module rear wall39may also be attached to the frame38or the frame elements41by means of fastening means45.

Moreover, it may be provided that an attachment housing46is formed, which is arranged on the module rear wall39and serves to accommodate electronic components. Furthermore, a plug47may be arranged in the attachment housing46, which plug47serves the connection of a graphic display48. For the sake of simplicity, the attachment housing46may also be viewed as a part of the module rear wall39.

FIG.6shows the display module26in a sectional representation of the view inFIG.5, wherein, however, inFIG.6the display module26is shown in its state accommodated in the press beam7. In this regard, equal reference numbers and/or component designations are again used for equal parts as inFIGS.1to5. In order to avoid unnecessary repetitions, it is pointed to/reference is made to the detailed description inFIGS.1through5.

As can be seen inFIG.6, it may be provided that a first sealing element49is arranged between the covering screen27and a first recess base50of the first recess tier17. Moreover, it may be provided that a second sealing element51is arranged between the attachment housing46and/or the module rear wall39and a second recess base52of the second recess tier18. The sealing elements49,51may have a circumferential design, so that the display module26can be accommodated in the recess16so as to be protected against environmental influences.

As can further be seen fromFIG.6, it may be provided that the display module26can be fixed in the press beam7by means of fastening means54. In this regard, the fastening means54can be inserted into the press beam7from its rear side24.

Moreover, it may be provided that the two sealing elements49,51are flexible and have a certain thickness, so that a sufficient sealing can be achieved in both sealing planes when pressing the display module26against the press beam7.
