SUMMARY OF THE INVENTION The object of the invention is to improve a machine tool of the type mentioned at the outset by means of which, in the starting state, a large-sized machine which is wider than the clamping table of the machine tool. The purpose is to be able to separate the plate sections to be machined from the plate.

[0006]

In order to solve the above-mentioned problems, in the configuration of the present invention, a support device at the same level as the tensioning table is arranged in front of the tensioning table on an extension of the Y axis, The support device is of the same length or shorter parallel to the X axis and is wider than the tensioning table in the Y direction, and a large plate in the X direction is disposed on the support device. Rollers or sliding devices are provided on the upper surface for the movement of the plate section to be cut along the cutting line onto the tensioning table and for the rest of the plate to be returned to the support device.

What is important for the invention is that the support device can be loaded with a large-sized plate, which is then manually or mechanically fed towards the tensioning table and divided by a milling and / or sawing device. A cutting is to be performed in each case to separate the plate sections to be machined in one working stroke of the machine tool. Cutting with a milling machine or with a milling device is selected when the respective cutting line does not extend linearly and consistently from one plate edge to the other. Conversely, saw cutting is selected for a consistent cutting line in the X direction of the machine tool. It is thus possible, with some machine tools according to the invention, to separate the corner sections from large-sized plates, in which case the turning of the plates in the plane of the plates, even in the intricate cutting pattern of the individual cutting pieces. Alternatively, the cutting line can be moved by a milling or sawing device by means of a suitable feed. For this purpose, the movement of the feed table for receiving the sawing device in the direction of the X-axis of the machine tool is used, and the plane of the saw blade of the sawing device is correspondingly oriented in the X-direction. The milling and sawing devices may be arranged directly on the respective feed slides, and in other cases the necessary milling or sawing devices may be

Can be moved in the direction of. Thus, the suction chuck can be positioned on either side of the cutting line either below the plate section to be cut off, or below the remaining adjacent section that is later returned to the support device again.

In order to precisely align the entire plate, in particular the plate section separated from the plate, in the working area of the machine tool, a stop device is provided on the side of the clamping table remote from the support device, In the working state, the device is arranged at a height on the side of the narrow surface where the plate abuts. The stopper device may be a stopper ruler (Anschlaglineal) that can be positioned in the Y-axis direction of the machine tool. It is particularly advantageous if the stop device is arranged on a slide of the machine tool, the slide being movable in the direction of the Y axis, in particular having a Y slide that is movable in the direction of the Y axis. ing. Since machine tools of this type are usually programmed, the required position of the stop device can be defined by program control. In an advantageous manner in this case, the cutting line extending in the X direction can always be located at the same Y coordinate when separating the plate sections, so that the suction chuck, which supports the plate on both sides of the cutting line, also has a cutting process. At this time, it may be always maintained at the same position.

In order to engage the stopper device of the Y-feed slide unhindered in the working area of the machine tool during the cutting process, the stopper device is configured to be adjustable in height,
That is, it is movable in the normal Z direction of the machine tool. In a preferred embodiment, the stop device comprises two liftable stop pins, which are arranged at a distance from one another.

This brings the plate section to be moved and cut off on the tensioning table at the exact position in the XY plane of the machine tool.

The adjustment of the suction chuck of the clamping table may be performed manually or mechanically. In an advantageous embodiment, at least the cross beam of the tension table is moved via the machine slide, for which the machine slide has a driving device, which can be engaged with the cross table of the tension table. It is.
It is particularly advantageous to use the existing stop device, in particular the stop pin of the stop device, at the same time as a driving device, so that the stop device or the stop pin has a dual function. Based on the mechanical adjustment of the cross beam of the tension table, the plate section fixed and separated on the tension table is further divided by separating and cutting in the Y direction.
The plate parts thus formed can be separated from one another in the X direction, so that small plate parts can also be machined around. For example, the plate portions separated from each other can be milled along the narrow surface extending in the Y direction.

In order to remove the separated plates or individual plate parts from the working area of the machine tool after machining, a lowering suction-fixing device is arranged on the feed table, via which the clamping device is tightened. After release from the table, the plate or plate part is conveyed in the direction of the X axis to the end of the tensioning table, where a receiving device is arranged, which receives the plate from the suction fixing device and conveys it. Deliver to device.

In a possible use case, a support device arranged in front of the tensioning table is not required or obstructed. For this purpose, the rolling elements or sliding devices of the support device are arranged on the support, which can be moved outward from the area in front of the tensioning table. One support guide required for the support can be arranged on the bed of the machine tool, whereby a particularly accurate mounting of the support device is achieved.
