- the tool holders 16, 17 accommodate stamping tools 19, 20 of a conventional type.
- the tool holder 18 is provided for a tool 21 which, in the illustrated phase of processing the sheet metal 10, is inserted with an upper tool part 22 into the upper tool holder 5 and with a lower tool part 23 into the lower tool holder 9.
- the tool 21 is used for deburring cut edges 24 on the underside of the sheet 10.
- the cut edges 24 have previously been created by punching the sheet 10 by means of the punching tools 19, 20.
- the punching tools 19, 20 were inserted one after the other with their punching dies into the upper tool holder 5 and with their punching dies into the lower tool holder 9 of the machine 1.
- a total of four slots were punched out on the sheet 10 with cut edges 24 adjoining one another in a rectangular manner on the underside of the sheet. Burrs were formed on all cut edges 24.
- the plunger 6 is raised on the upper frame leg 3 of the machine frame 2 with the upper tool holder 5 and the upper tool part 22 of the tool 21 fixed therein.
- workpiece supports 25 are aligned on their upper side with the free axial end of a pin-like rolling body 26 designed as a pressure roller.
- the sheet metal 10 is in the position shown in FIG. 1.
- the sheet metal 10 is first positioned relative to the tool 21 by means of the coordinate guide 11 such that one of the cut edges 24 of the slot arranged on the sheet metal 10 at the edge comes to lie above the roller body 26 of the tool 21. Then will the plunger 6 is lowered with the upper tool part 22 of the tool 21.
- the upper part 22 of the tool runs with its bottom side, in particular with counterpressure balls 27 shown in FIG. 2, which can be rotated on all sides and serve as counter bearings, on the upper side of the sheet 10 resting on the workpiece supports 25 of the lower part 23 of the tool.
- the sheet metal 10 is pressed downward with elastic deformation of the workpiece supports 25.
- the pressure surface 28 extends along both surfaces of the sheet 10 that form the cutting edge 24. It is therefore both the underside of the sheet 10 and which overall adjoining this sectional area of the sheet 10 'genüber. Overall, the relationships according to FIG. 2 result.
- the sheet 10 pressurized by the tool 21 is moved relative to the tool 21 by means of the coordinate guide 11 in such a way that the rolling body 26 with the pressure surface 28 completely travels the cut edges 24 of the slot in question on the sheet 10.
- the rolling body 26 rotates about a vertical feed axis of rotation 29 and rolls with its pressure surface 28 on the cut edges 24.
- the pin-like rolling body 26 is on a base body 30 of the lower tool part 23 a rotary bearing 31 is rotatably supported.
- Means. of the pin-like rolling body 26 can in particular also deburr cut edges with narrow radii.
- a rotary setting of the roller body 26 by a corresponding adjustment movement of the tool 21 in the direction of the double arrow 32 is not required when the direction of the machined cutting edge changes.
- the burr protruding from the cut edges 24 is removed by stamping.
- the cut edges 24 are chamfered slightly by means of the roller body 26.
- the shape of the chamfer formed is determined by the geometry of the pressure surface 28 on the rolling body 26.
- the chamfer shape could also be influenced by varying the orientation of the feed axis of rotation 29 of the rolling body 26.
- the plunger 6 is raised until the sheet metal 10 is released.
- the workpiece supports 25 are relieved of pressure and are in their initial state, in which they are aligned on their upper side with the free axial end of the rolling body 26.
- the rolling body 26 is again completely below the plate 10. This can therefore be positioned with the cutting edges 24 of the next slot in the above manner relative to the tool 21.
- the Rolling body 26 deburred and chamfered cut edges 24.
- the processed plate '10 is now moved away from the tool 21 and transferred to an unloading position. Starting from this unloading position, the sheet 10 is finally removed from the machine 1.

- a rolling body 46 designed as a pressure roller is rotatably mounted on the lower tool part 43 about a horizontal feed axis of rotation 49.
- a pressure surface 48 is formed by a bead-like radial expansion of the rolling body 46.
- the geometry of the pressure surface 48 is matched to the distance between opposing cut edges 24 of the sheet 10 and is selected such that both cut edges 24 can be pressurized at the same time. In this case, the pressure surface 48 encompasses both cut edges 24.
- the roller body 46 could, for example, with a corresponding cut edge distance also processed only a single cut edge and be encompassed by the pressure surface 48.
- a counter-pressure roller 47 is rotatably supported as an abutment about an axis running parallel to the feed axis of rotation 49 of the rolling body 46.

- the tool 41 basically corresponds to the tool 21. In particular, cutting edges that do not run in a straight line can also be processed with the tool 41.
- the tool 41 can be rotated in the direction of the double arrow 32 about the axis 1 of the relative stroke movement of the upper tool part 42 and the lower tool part 43, which axis forms an orientation axis of rotation. If necessary, the rotation is set by means of the numerically controlled rotary drive provided for the upper tool holder 5 and the lower tool holder 9 of the machine 1. Alternatively, the tool 41 can be freely rotated about the axis.
- Cutting edges which also run almost arbitrarily, can be deburred with a tool 61, as shown in FIG. 4.
- the tool 61 has a tool top part 62 soie a tool bottom part 63.

Rotary adjustment of the tool 61 in the case of non-linear cut edge profiles is used at most for the upper tool part 62.
- the tools 21, 41, 61 can all be replaced in the upper tool holder 5 or in the lower tool holder 9 of the machine 1. Different types of tools can be kept on the cross rail 15 of the coordinate guide 11 at the same time. It is possible to use tools 21 41, 61, in addition to the deburring and shaping of cut edges described above, also for workpiece shaping, for example for creating beads on the sheet metal 10. Conversely, it is conceivable to use shaping tools which have been customary to date for deburring and which are provided by corresponding rolling elements, in particular shaping rollers and / or use balls ..
- FIG. 5 shows in the upper partial representation the formation of a burr on the cutting edge 24 of the sheet 10.
- a punching punch and a punching die as are used in the case of the punching tools 19, 20, can be seen.
