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

摘要： In one embodiment, a wear component for use in a manufacturing process includes at least one operating surface for absorbing a force generated during the manufacturing process and at least one wear indicator groove in the at least one operating surface and having a varying depth. In another embodiment, a wear component includes at least one operating surface for absorbing a force generated during the manufacturing process, a first wear indicator groove in the at least one operating surface and having a first depth, and a second wear indicator groove in the at least one operating surface and having a second depth that is different from the first depth.
