Abstract

A bending device for forming a product from a workpiece includes a shaft driven to rotate by a motor, an actuator including an extendable end configured to secure a portion of the workpiece, and a die coupled to the shaft and driven about an axis. The die includes a peripheral portion including a channel configured to receive the workpiece. The channel includes a first end and a second end offset from the first end in a direction parallel to the axis. Rotation of the die about the axis causes the workpiece to bend along the channel.

First claim

What is claimed is:

1. A method for forming a cable storage bracket from a workpiece including a first end and a second end, the method comprising:
positioning a first portion of the workpiece within a channel of a die, the first portion being positioned between the first end of the workpiece and the second end of the workpiece;
securing, by an actuator, a second portion of the workpiece against a block that is spaced apart from the channel of the die by a gap, the second portion being positioned between the first portion and the first end of the workpiece;
biasing the workpiece against a wall of the channel;
rotating the die about an axis to bend the workpiece to a configuration in which the first end of the workpiece is bent about the axis beyond the second end of the workpiece, the first end of the workpiece being offset from the second end of the workpiece in a direction parallel to the axis;
forming a first leg extending from the first end of the workpiece and a second leg extending from the second end of the workpiece; and
securing the first leg of the workpiece relative to the second leg of the workpiece to form the cable storage bracket.

2. The method of claim 1 , wherein forming the first leg extending from the first end of the workpiece and the second leg extending from the second end of the workpiece includes releasing the second portion to permit the first end of the workpiece to retract to a position adjacent the second end of the workpiece.

3. The method of claim 2 , wherein forming the first leg extending from the first end of the workpiece and the second leg extending from the second end of the workpiece includes moving the first end of the workpiece and the second end of the workpiece to be aligned in a common plane.

4. The method of claim 1 , wherein securing the first leg of the workpiece relative to the second leg of the workpiece includes securing at least one cross-member between the first leg and the second leg.

5. The method of claim 1 , wherein rotating the die further includes bending the workpiece along the channel in a helical shape.

6. The method of claim 1 , wherein securing, by the actuator, the second portion of the workpiece against the block further includes extending the actuator to clamp the second portion between the block and a distal end of the actuator.

7. A method for forming a cable storage bracket from a workpiece including a first end and a second end, the method comprising:
positioning a first portion of the workpiece against a wall of the die, the first portion being positioned between the first end of the workpiece and the second end of the workpiece;
securing, by an actuator, a second portion of the workpiece against movement a block that is spaced apart from the wall of the die by a gap, the second portion being positioned between the first portion and the first end of the workpiece;
biasing the first portion of the workpiece against the wall of the die;
rotating the die about an axis to bend the workpiece to a configuration in which the first end of the workpiece is bent about the axis beyond the second end of the workpiece, the first end of the workpiece being offset from the second end of the workpiece in a direction parallel to the axis,
forming a first leg extending from the first end of the workpiece and a second leg extending from the second end of the workpiece; and
securing the first leg of the workpiece relative to the second leg of the workpiece to form the cable storage bracket.

8. The method of claim 7 , wherein forming the first leg extending from the first end of the workpiece and the second leg extending from the second end of the workpiece includes releasing the second portion to permit the first end of the workpiece to retract to a position adjacent the second end of the workpiece.

9. The method of claim 8 , wherein forming the first leg extending from the first end of the workpiece and the second leg extending from the second end of the workpiece includes moving the first end of the workpiece and the second end of the workpiece to be aligned in a common plane.

10. The method of claim 7 , wherein securing the first leg of the workpiece relative to the second leg of the workpiece includes securing at least one cross-member between the first leg and the second leg.

11. The method of claim 7 , wherein rotating the die further includes bending the workpiece along the wall in a helical shape.

12. The method of claim 7 , further comprising positioning the first portion of the workpiece adjacent a flange extending from the wall of the die.

13. The method of claim 7 , further comprising positioning the first portion of the workpiece between a first flange and a second flange, the first flange and the second flange extending from the wall of the die.

14. The method of claim 7 , wherein securing, by the actuator, the second portion of the workpiece against the block further includes extending the actuator to clamp the second portion between the block and a distal end of the actuator.

15. The method of claim 7 , wherein rotating the die about the axis to the configuration in which the first end of the workpiece is bent about the axis beyond the second end of the workpiece includes guiding the workpiece along a circumference of the die such that the second portion of the workpiece is offset from the first portion.

16. A method for forming a cable storage bracket from a workpiece including a first end and a second end, the method comprising:
providing a die having an axis and a channel with a first end and a second end adjacent to the first end of the channel, the second end of the channel being offset from the first end of the channel along a direction parallel to the axis;
positioning a first portion of the workpiece within the channel at or adjacent to the first end of the channel, the first portion being positioned between the first end of the workpiece and the second end of the workpiece;
securing, by an actuator, a second portion of the workpiece against a block that is spaced apart from the channel of the die by a gap, the second portion being positioned between the first portion and the first end of the workpiece;
biasing the workpiece against a wall of the channel;
rotating the die about an axis to bend the workpiece to a configuration in which the first end of the workpiece is bent about the axis beyond the second end of the workpiece, the first end of the workpiece being offset from the second end of the workpiece in a direction parallel to the axis,
forming a first leg extending from the first end of the workpiece and a second leg extending from the second end of the workpiece; and
securing the first leg of the workpiece relative to the second leg of the workpiece to form the cable storage bracket.

17. The method of claim 16 , wherein rotating the die about the axis to a configuration in which the first end of the workpiece is bent about the axis beyond the second end of the workpiece includes guiding the workpiece along the channel such that the second end of the workpiece is positioned adjacent the second end of the channel.

18. The method of claim 16 , wherein forming the first leg extending from the first end of the workpiece and the second leg extending from the second end of the workpiece includes releasing the second portion to permit the first end of the workpiece to retract to a position adjacent the second end of the workpiece.

19. The method of claim 18 , wherein forming the first leg extending from the first end of the workpiece and the second leg e
