Abstract

The invention describes a bending press, in particular a press brake, with a stationary bottom press beam or press table and a top press beam which can be displaced relative to the bottom press beam or press table by means of a displacement drive. The bottom press beam or press table or a machine table or machine frame supporting the bottom press beam has at least one recess affording foot room for an operator on a control side of the bending press.

Claims

1. A bending press comprising a stationary bottom press beam and a top press beam which can be displaced relative to the bottom press beam by a displacement drive, a bending stamp mounted on the top beam press and a cooperating bending die mounted on the bottom press beam, and at least one recess below or in the bottom press beam on a control side of the bending press affording room for an operator'"'"'s feet, wherein a foot rest higher than a standing surface of the bending press and height-adjustable is disposed in the recess, and a deposit with a deposit surface is disposed on the control side in front of the bottom press beam which can be positioned in different positions relative to the bottom press beam by a displacement system and a fixing device,

wherein the deposit can be displaced between an operating position and a non-operating position, and is mounted on the bottom press beam so that it can be pivoted about an essentially horizontal pivot axis.

2. The bending press according to claim 1, wherein the recess has a horizontal internal width of at least 750 mm.

3. The bending press according to claim 1, wherein two mutually spaced apart recesses are provided, each with a horizontal internal width of at least 200 mm, and a support element with a width of between 50 mm and 250 mm is disposed between the two recesses.

4. The bending press according to claim 1, wherein the recess has a horizontal depth of at least 450 mm as measured from the front face of the bending press.

5. The bending press according to claim 1, wherein the recess extends at least 200 mm behind a bending plane formed by the press beam.

6. The bending press according to claim 1, wherein the recess has a vertical internal height of at least 650 mm in the middle.

7. The bending press according to claim 1, wherein a top delimiting surface of the recess has a cambered rounded region.

8. The bending press according to claim 1, wherein a top delimiting surface of the recess is formed by the bottom face of the bottom press beam.

9. The bending press according to claim 1, comprising a machine frame having side panels wherein the bottom press beam is secured to the side panels of the machine frame.

10. The bending press according to claim 1, wherein the inclination of the foot rest can be adjusted.

11. The bending press according to claim 1, wherein a foot switch, which is connected to a control device of the bending press and can be operated by the feet, is disposed in the recess.

12. The bending press according to claim 1, wherein an illuminating foreground light system comprising a lamp means is disposed in front of the bending plane in the front workspace between the top press beam and bottom press beam.

13. The bending press according to claim 12, wherein an illuminating background light system comprising a lamp means is disposed behind the bending plane in the rear workspace behind the bottom press beam on a rear stop system.

14. The bending press according to claim 13, wherein the foreground light system or background light system is formed by a lamp crosshead disposed at least approximately parallel with the press beams.

15. The bending press according to claim 13, wherein the lamp means of the foreground light system or background light system is integrated in the interior of a stationary machine housing and has at least one light outlet orifice, in particular a light outlet slot.

21. The bending press according to claim 1, wherein the bending press has a lamp marker system by means of which a bending line marker lying in the bending plane formed by the press beam can be directed onto the top face of a workpiece positioned between a bending die secured to the bottom press beam and a bending stamp secured to the top press beam.

22. The bending press according to claim 1, characterized in that the deposit surface has a depth of at least 150 mm oriented transversely to the bottom press beam in an approximately horizontal operating position.

23. The bending press according to claim 1, wherein an elbow rest is disposed in front of the bottom press beam, on the deposit.

24. The bending press according to claim 1, wherein the deposit surface is disposed between 0 mm and 150 mm underneath the top edge of the bottom press beam in the operating position.

25. The bending press according to claim 1, wherein a control panel co-operating with a control device of the bending press is disposed on the control side on a stationary machine housing in front of and above the top press beam.

26. The bending press according to claim 25, wherein the control panel can be positioned in different positions relative to the machine housing by an adjusting device.

16. A bending press comprising a stationary bottom press beam and a top press beam which can be displaced relative to the bottom press beam, a bending stamp mounted on the top beam press and a cooperating bending die mounted on the bottom press beam, at least one recess below or in the bottom press beam on a control side of the bending press affording room for an operator'"'"'s feet, wherein a foot rest higher than a standing surface of the bending press and height-adjustable is disposed in the recess, and a deposit with a deposit surface is disposed on the control side in front of the bottom press beam which can be positioned in different positions relative to the bottom press beam,

wherein an illuminating foreground light system comprising a lamp means is disposed in front of the bending plane in the front workspace between the top press beam and bottom press beam,

wherein an illuminating background light system comprising a lamp means is disposed behind the bending plane in the rear workspace behind the bottom press beam on a rear stop system, and

wherein the background light system comprises a lamp marker system, which can direct a lamp marker caused by the lamp means by a displacement mechanism towards one stop element of a group of several stop elements.

17. The bending press according to claim 16, wherein the displacement mechanism of the lamp marker system is connected so as to communicate with the control device controlling the rear stop system and the lamp marker can be positioned by the displacement mechanism on whichever stop element should be used as determined by the control device.
