Abstract

A workpiece manipulation device for a swivel bending machine includes a base rack; a manipulation device carrier arranged on the base rack so as to be displaceable by a manipulation device carrier guide in a Y-axis relative to the base rack; a manipulation arm arranged on the manipulation device carrier so as to be displaceable by a manipulation arm guide in a Z-axis relative to the manipulation device carrier; a first rotary punch arranged on the manipulation arm, and a second rotary punch arranged on the manipulation device carrier. The manipulation device carrier is configured in an L-shape and has a first limb, which extends along a Y-axis, and a second limb, which extends along the Z-axis. The manipulation arm guide is formed on the second limb, and a distance between the manipulation arm guide and the rotational axis of the first rotary punch is greater than 1000 mm.

First claim

2 . The workpiece manipulation device ( 3 ) according to claim 1 , wherein the distance ( 24 ) between the manipulation arm guide ( 16 ) and the rotational axis ( 20 ) of the first rotary punch ( 19 ) is between 130% and 70% of a length ( 46 ) of the first limb ( 22 ) of the manipulation device carrier ( 12 ).

3 . The workpiece manipulation device ( 3 ) according to claim 1 , wherein the distance ( 24 ) between the manipulation arm guide ( 16 ) and the rotational axis ( 20 ) of the first rotary punch ( 19 ) is between 1000 mm and 3000 mm.

4 . The workpiece manipulation device ( 3 ) according to claim 1 , wherein the manipulation device carrier ( 12 ) has a first cheek ( 25 ) and a second cheek ( 26 ), which has an L-shaped configuration, wherein the first cheek ( 25 ) and the second cheek ( 26 ) are arranged at a distance ( 27 ) from one another and are coupled to one another by means of webs ( 28 ).

5 . The workpiece manipulation device ( 3 ) according to claim 1 , wherein a further manipulation device carrier ( 29 ) is formed, which is arranged on the base rack ( 7 ) so as to be displaceable by a further manipulation device carrier guide ( 30 ) in a Y-axis ( 14 ) relative to the base rack ( 7 ), wherein the further manipulation device carrier ( 29 ) comprises multiple manipulation elements ( 31 ), which are arranged at a distance from one another in an X-axis ( 18 ), wherein the manipulation elements ( 31 ) are displaceable in a Z-axis ( 17 ) relative to the further manipulation device carrier ( 29 ).

6 . The workpiece manipulation device ( 3 ) according to claim 1 , wherein a first guide rail ( 40 ) and a second guide rail ( 41 ) are arranged on the second limb ( 23 ) of the manipulation device carrier ( 12 ), wherein the manipulation arm guide ( 16 ) comprises a first guide carriage ( 42 ) and a second guide carriage ( 43 ), which are guided in the first guide rail ( 40 ), and wherein the manipulation arm guide ( 16 ) comprises a third guide carriage ( 44 ) and a fourth guide carriage ( 45 ), which are guided in the second guide rail ( 41 ).

7 . The workpiece manipulation device ( 3 ) according to claim 1 , wherein a rotation motor ( 39 ) for rotating the first rotary punch ( 19 ) is formed on the manipulation device carrier ( 12 ).

8 . A processing system ( 1 ) for bending workpieces ( 4 ),
wherein the processing system ( 1 ) comprises: a swivel bending machine ( 2 ); and a workpiece manipulation device ( 3 ) for feeding workpieces ( 4 ) to the swivel bending machine ( 2 ), wherein the workpiece manipulation device ( 3 ) is formed according to claim 1 .

9 . The processing system ( 1 ) according to claim 8 , wherein the manipulation arm ( 15 ) has a clearance ( 37 ) in the region of the first rotary punch ( 19 ), which clearance ( 37 ) corresponds with the swivel bending machine ( 2 ).

10 . The processing system ( 1 ) according to claim 8 , wherein the swivel bending machine ( 2 ) has a lower machine table ( 5 ), wherein the base rack ( 7 ) is coupled with the lower machine table ( 5 ) at a first longitudinal end ( 8 ), and wherein, in a region distanced from the first longitudinal end ( 8 ), the base rack ( 7 ) has a support foot ( 11 ) for being supported on the floor.

11 .
