Embodiment Construction

[0023] Figure 1 to Figure 2 An example of a workpiece 10 is shown that can be bent using a bending die 100 ( image 3 , Figure 4 , Figure 6 and Figure 7 )Produce. The workpiece 10 may be a thin-walled part manufactured from sheet metal. The workpiece 10 includes a body portion 12 and a flange portion 14 . The main body portion 12 has a profiled shape including a first portion 16 , a second portion 18 and a radiused portion 20 . The first portion 16 and the second portion 18 are each generally planar, but extend at an angle relative to each other. The rounded portion 20 interconnects the first portion 16 and the second portion 18 by providing a rounded profile between the first portion 16 and the second portion 18 .

[0024] The body portion 12 intersects the flange portion 14 at a contoured bend line 22 . The contoured bend line 22 extends continuously along the main body portion 12 , including along the first portion 16 , the radiused portion 20 , and the second p...

Abstract

A method for bending a workpiece includes positioning a first bending surface adjacent to the workpiece; positioning a second bending surface adjacent to the workpiece; and moving the first bending surface and the second bending surface linearly toward the workpiece while the second bending surface rotates with respect to the first bending surface such that the first bending surface bends a first portion of the workpiece, the second bending bends a second portion of the workpiece, and the first portion of the workpiece, and the second portion of the workpiece are disposed on a first side of a bend line formed on the workpiece by the first bending surface and the second bending surface.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 418,939, filed December 2, 2010. technical field [0003] The present invention relates to the field of sheet metal bending and, more precisely, the invention relates to bending dies for bending sheet metal around fillet-like profiles. Background technique [0004] Sheet metal bending equipment is well known. Generally, sheet metal bending dies operate by supporting the workpiece between two relatively movable die sections. For example, the workpiece may be held in a fixed position relative to a non-moving backing portion of the die, while an anvil portion of the die is moved into contact with the workpiece, causing a portion of the workpiece to bend about a bend line. [0005] Although this type of bending operation is simple when applied to a flat workpiece, the complexity of the operation is greatly increased when the workpiece ha...
