Patent ID: 8789402

Claim:
An apparatus for bending a workpiece, comprising: a backing surface that is operable to support the workpiece; a mounting structure that is operable to move linearly between a first position and a second position, wherein movement from the first position to the second position is in a direction toward the backing surface; a first bending surface that is fixedly connected to the mounting structure for movement in unison with the mounting structure, wherein the first bending surface is operable to engage and deform a first portion of the workpiece during linear motion of the mounting structure from the first position to the second position; and a second bending surface that is rotatably connected to the mounting structure such that a rotational axis of the second bending surface moves in unison with the mounting structure and the second bending surface rotates with respect to the first bending surface in response to movement of the mounting structure from the first position to the second position, wherein the second bending surface is operable to engage and deform a second portion of the workpiece during linear motion of the mounting structure from the first position to the second position, and the first bending surface is positioned with respect to the second bending surface such that the first bending surface and the second bending surface are operable to define a flange on the workpiece by deformation of the first portion of the workpiece and deformation of the second portion of the workpiece.
