Abstract

A bending machine with a bending information display apparatus has a machine frame, a longitudinally extended, fixed machine table, and a longitudinally extended press beam. The longitudinal expanse and the press beam movement direction define a working plane. An insertion plane essentially normal to the working plane is defined by an upper machine table flat side or a lower tool disposed thereon. The working plane establishes a front working and manipulation space and a closed rear machine space. A projector disposed above the insertion plane in the rear machine space has a light beam path directed away from the insertion plane. A reflector disposed in the working and manipulation space has a first reflective surface pivotable by an angle to the horizontal so that a light beam incident from the projector beam path leaves the first reflective surface as a departing light beam toward the insertion plane.

First claim

The invention claimed is:

1. A bending machine with a bending information display apparatus for display of bending information,
wherein the bending machine has a machine frame and a longitudinally extended machine table, fixed in place, and a longitudinally extended press beam, which press beam is guided in the machine frame and held by a first drive means, so as to be movable relative to the machine frame, and
wherein the longitudinal expanse and the movement direction of the press beam define a working plane, and furthermore, an insertion plane is defined essentially normal to the working plane and by an upper flat side of the machine table or of a lower tool disposed on the machine table, and
wherein the machine frame furthermore has two side parts, which are spaced apart from one another by a machine width in the direction of the longitudinal expanse of the machine table and of the press beam, and
wherein the working plane establishes a front working and manipulation space and a rear machine space, distinguished from the front working and manipulation space,

wherein
a projector is disposed in the rear machine space and above the insertion plane, which projector has a light beam directed away from the insertion plane, and
wherein a reflector having a first reflective surface is disposed in the working and manipulation space, which first reflective surface is disposed so as to be pivoted by an angle relative to the horizontal, so that the light beam impacting the first reflective surface departs from the first reflective surface as a departing light beam of the reflector in the direction of the insertion plane.

2. The bending machine according to claim 1 , wherein at least one of the projector and/or and the reflector is pivotally mounted on the machine frame to orient the light beam over a section along the longitudinal expanse.

3. The bending machine according to claim 1 , wherein at least one of the projector and the reflector is disposed on a region of the side parts or in the region of the side parts.

4. The bending machine according to claim 1 , wherein the machine table and/or a metal sheet to be formed, which is disposed in the insertion plane, and/or a floor surface in the front working and manipulation space and/or a surface of a bending tool disposed in the press beam form a first display surface.

5. The bending machine according to claim 4 , wherein the reflector has a second reflective surface, wherein the first and the second reflective surface are disposed within the light beam of the projector, and surface normal line vectors of the two surfaces enclose an angle relative to one another.

6. The bending machine according to claim 5 , wherein the press beam forms a second display surface.

7. The bending machine according to claim 6 , wherein at least one of the first display surface and the second display surface is configured at discrete positions along the longitudinal expanse.

8. The bending machine according to claim 1 , wherein at least one of the projector and the reflector is disposed, in movable manner, in a guide that is disposed oriented parallel to the longitudinal expanse.

9. The bending machine according to claim 8 , wherein at least one of the projector and the reflector is connected with the guide so as to move, by way of a second drive means.

10. The bending machine according to claim 1 , wherein the reflector is disposed in a holding apparatus comprising an axle, which holding apparatus is movable between a protection position and a work position.

11. The bending machine according to claim 10 , wherein the holding apparatus is disposed behind the working plane in the protection position.

12. The bending machine according to claim 10 , wherein the holding apparatus is disposed above the projector in the protection position.

13. The bending machine according to claim 10 , wherein the projector is formed by a laser having a deflection unit.

14. The bending machine according to claim 1 , wherein the projector is connected with a machine controller and/or a process guide system, and wherein a data-technology connection exists with a work preparation system or CAD system.

15. The bending machine according to claim 14 , wherein at least one of a position-locating apparatus and a command issuance apparatus is connected with the machine controller.

16. The bending machine according to claim 15 , wherein the connection is configured to be wireless.

17. The bending machine according to claim 15 , wherein the position-locating apparatus and/or a command issuance apparatus is formed by an article of clothing.

18. The bending machine according to claim 1 , wherein the bending information is formed by at least one of the group of workpiece contour, bending line, control panel, status data of the press beam, orientation information, reference angle, piece counter, and regions on the sheet metal to be formed that have an increased risk of injury during the bending process.

19. The bending machine according to claim 1 , wherein the bending information comprises animated orientation information.
