Patent ID: 11045855

Abstract:
The bending machine (100) has an upper beam (211) and a lower beam (212), each of the beams (211, 212) having a clamping element extending therefrom adapted for clamping an elongated flat sheet metal workpiece (218) with a portion extending from the machine in cantilever fashion. Bending tool carriers (221, 222) having a bending tool (223, 224) extending therefrom are movable relative to the beams so that the bending tool (223, 224) can extend and pivot to form an elongated bend in the workpiece (218). A plurality of wedges (251, 252) are selectively extendable between the beams (211, 212) and the carriers (221, 222) to provide uniform depth of the bend in the workpiece (218) along the length of the bend, the depth of extension being adjustable with ball screws (261, 262) attached to synchro or servomotors (265, 266).
