摘要： A rotary bending device (10) for bending workpiece includes a saddle (22), a rocker (24), and first and second alignment elements (66, 68). The saddle (22) includes a longitudinally extending cavity (42) in which the rocker (24) is received, and the rocker (24) rotates relative to the saddle (22) between a neutral position and a bending position for bending the workpiece. The first alignment element (68) is provided on the rocker (24), and the second alignment element (66) is positioned to engage the first alignment element to limit axial movement of the rocker (24) relative to the saddle (22) during rotation of the rocker (24) between the neutral position and the bending position. The rocker (24) may tangentially contact a bearing surface of the cavity (42) at no more than two lines of tangential contact during rotation. The rocker (24) may further include a longitudinally extending shoulder (58), and the device may further include a return element (28) positioned to contact the shoulder (60) for biasing the rocker (24) toward the neutral position.
