AbstractA cable bender includes two bending members rotatably joined together about a common pivot axis, one of the bending members having a hydraulic cylinder associated therewith such that force may be applied causing the piston shaft of the cylinder to extend and cooperate with a tie arm extending between the bending members to drive one of the bending members in a curved path about the pivot axis.
Field of SearchDeforming indeterminate-length work
With pivotal tool (e.g., sheet metal bender)
Curved die surface
With coacting movable tool
Clamp rotatable about fixed axis (e.g., bending brake)
Clamp structure constitutes sole initial metal-deforming force-reaction means (i.e., is passive tool)
With means to rotate clamp about fixed axis
Pivotal motion only
BY OR WITH WORK-CONSTRAINER AND/OR MANIPULATED WORK-FORCER
Comprising lever manipulated to force work
